▼ A seven months analysis of pollution levels for particulate matter (PM2.5) in air, toxic metals in
snow, as well as noise was undertaken and mapped in the Mission Industrial Area (MIA) and South
St. Boniface (SSB) neighbourhood in Winnipeg, Manitoba. Daytime respirable fine particulate
matter (PM2.5) was monitored by Dylos DC 1700 PM air quality monitor and A-weighted noise
level measurements was taken by Reed Digital Sound Level Meter. Evaluation of toxic metals (lead,
chromium, arsenic, nickel, mercury and zinc) in snow were measured and compared to different
pollution indices, including: contamination factor (cf), degree of contamination (cd) and pollution
load index (PLI) for heavy metals.
The PM2.5 Canadian Ambient Air Quality Standard of 28 μg/m3 was sporadically exceeded
downwind of the property line of the scrap metal shredder, with 5 out of 35 days averaging between
28.9 μg/m3 to 38.1 μg/m3. During the wildfire in August, the levels were high in the residential area
at 21.9 and 25.6 μg/m3 although other
monitoring days ambient levels averaged 0.59 μg/m3 to 9.81
μg/m3, indicating satisfactory PM2.5 levels. However, the cf indices were high for lead, zinc, nickel
and mercury compared to background levels in MIA and SSB. One-way ANOVA and Spearman
rank correlation analysis revealed statistically significant higher levels for PM2.5 and heavy metals
concentration in snow MIA and SSB. Mapping showed the highest pollution of PM2.5, contaminant
factors (cf), noise were downwind of IM and radiating out, but reducing and remaining significantly
above background levels. Also, the noise levels regularly exceeded the city by-law level in the MIA,
on the properties adjacent to the scrap metal shredder, with 90% of the sampling time over 200
hours (number of days= 35). The 55 dBA by-law guideline was also exceeded in the residential
areas on 4 days out of the 33 monitored. This research shows high particulate matter, toxic heavy
metals and noise levels adjacent to the scrap metal shredding operation in IM, which suggests the
need for regulatory action to enclose the shredder for pollution control.

▼ Wireless Sensor Networks have emerged as an exciting field in recent years. There have been numerous studies on how to improve and standardise different aspects of wireless sensor networks. This paper aims to develop a wireless sensor network suitable for environmental monitoring applications. More specifically this paper aims to address the limited communication range of the existing wireless sensor technology. In order to achieve the desired objectives, we have initially developed a hardware platform and then integrated the hardware with a long range RF radio module to achieve the goals. The system is further enhanced with mesh networking capabilities to increase the communication range and overall reliability of the network. The developed wireless sensor network is composed of sensors, microcontroller, RF radio module, antenna and expansion connectors for additional sensors and peripheral devices. The developed wireless sensor network has been rigorously tested under three different scenarios to ensure the correct operation of the mesh network, communication range and effect of environmental obstacles such as vegetation and trees. The developed wireless sensor network has been proven to be a suitable platform for environmental monitoring applications and the modular design has made it very easy to optimise it for different applications.

▼ Listeria monocytogenes is one of the deadliest foodborne pathogens, accounting for about 20% of the deaths caused by foodborne illnesses in the US. Historically, L. monocytogenes has been a big concern for Ready-to-Eat products (ice cream, deli meats, etc.), but in the last decade, there have been several listeriosis outbreaks associated with fresh produce (e.g. cantaloupes, apples, celery, packaged salad) becoming a produce safety concern. Some of these outbreaks have been traced back to the produce farm (pre-harvest) and the operations after harvesting (post-harvest). Though there is research focusing on the prevalence of Listeria in the pre-harvest environment, there is a need for studies investigating Listeria at the post-harvest level. This research project, focused on gaining a better understanding of the prevalence, persistence, and diversity of Listeria (including L. monocytogenes) in produce packinghouses. 11 packinghouses facilities were sampled four times during the packing season. The samples were obtained from different stationary (e.g. walls, drains, floors) and moving (e.g. bins, forklifts, pallets) non-food contact surfaces and equipment during operation hours. Isolates were processed to detect and isolate Listeria species (including L. monocytogenes). Listeria isolates were confirmed and fingerprinted. Listeria prevalence in these packinghouses was low (6.4%), and it varied among packinghouses. Drains, cold storages, and wet non-food contact surfaces were the sites with the highest Listeria prevalence. There were 3 cases of Listeria repeated isolation (same Listeria detected in the same site in at least 2 of the 4 visits). The diversity of Listeria in these packinghouses was high. The information gathered through this research provides a better understanding of where and what species of Listeria can be found in a produce packinghouse iv facility. This knowledge may be used to develop and implement mitigation strategies and interventions to control and/or reduce the risk of Listeria contamination in produce packinghouses.

▼ Monitoring has long been the challenge of a server administrator.
Monitoring diskhealth, system load, network congestion, and
environmental conditions like temperature are all things that can be tied into
monitoring systems.
Monitoring systemsvary in scope and capabilities, and many can fire off alerts for just about any configuration. The sysadmin then has the responsibility of weighing the alert and decidingif and when to act. In a High Performance Computing (HPC) environment, someof these failures can have a ripple effect, affecting a larger area than the physicalproblem. Furthermore, some temperature and load swings can be more drastic in anHPC environment than they would be otherwise. Because of this a timely, measuredresponse is critical. When a timely response is not possible, conditions can escalaterapidly in an HPC environment, leading to component failure. In this situation, anintelligent, automatic, measured response is critical. Here we present such a system, anovel approach to server
monitoring using integrated server hardware operating independently of the operating sytem, and capable not only of
monitoring temperatures,but also automatically responding to temperature events. Our proactive response system leverages standard HPC software and integrated server hardware. It is designedto intelligently respond to temperature events from a High Performance Computingperspective, looking at both compute jobs and server hardware.

▼ The focus of this research is to develop an event detection system for groundwater flooding. The groundwater
monitoring infrastructure is based on a Wireless Sensor Network, which can often lead to corrupted data values. The event detection system seeks to develop an algorithm to identify these corrupted data values and flag them as a false event to the user. It aims to maintain a high accuracy of true events, while keeping the occurrence of a false event to a minimum. The algorithm is based on threshold classification technique to identify the event and a statistical modified Z Score calculation to determine if the event is true or false. I ran the algorithm with an historic flood event and measured the accuracy of the results with a ROC curve. Results showed a 95% accuracy level but it also identified 8 out of 160 true events as false, which leads me to recommend a further analysis into the threshold that defined the algorithm. The technique would also need to be tested on larger dataset to validate this accuracy.

▼ Mountain pine beetle (Dendroctonus ponderosae Hopkins) is an endemic species in the forests of British Columbia that has become epidemic and reached infestation levels like never before. Different approaches have been taken in order to try and manage the forest and understand the processes affecting the behavior of mountain pine beetle. No single model has been entirely successful in unearthing the complexity of mountain pine beetle behavior. In this thesis, large spatial data sets of mountain pine beetle attacks, obtained from helicopter and ground surveys, and further adjusted for the incorporation of uncertainty, are studied using a spatial autocorrelation approach in a pattern-based analysis. The study of spatial patterns is carried out by simulating possible scenarios of the observed data set. Moran’s I is used to obtain an overall measure of spatial autocorrelation of the global pattern and Local Indicators of Spatial Autocorrelation, specifically Local Moran’s I, are used to identify local pockets of high levels of infestation (hot spots). Using a significance criterion, regions that have intense infestations are screened to retain those that are more pervasive, thus having a more robust set of results that can be more reliable. Different levels of significance can be used to allow for a more ‘liberal’ or ‘strict’ screening of results. Study of the sensitivity of the data model and detection approach is carried out by comparing the locations of hot spots obtained with different detection methods. A comparison between results derived from data sets containing only aerial data and those containing aerial and field data is useful to determine the impact and effectiveness of sending crews to groundtruth aerial surveys.

▼ The seasonal carbon dioxide (CO2) budget and its associated environmental controlling parameters, soil moisture, soil temperature and depth to frost were investigated throughout the growing period during the summer of 2004. The study site is located within the low arctic tundra environment at Daring Lake, NWT (62⁰52’N, 111⁰35’W). The CO2 fluxes from an area of heterogeneous tundra composition were intensely monitored. The net seasonal CO2 budget was approximated to be 10.2 g C-CO2 m-2 for 100 days (DOY 159-259) of the 2004 snow-free study period. The CO2 flux dynamic was found to differ between 4 identified seasonal periods—melt, pre-green, green and senescence. The controlling environment parameters (soil moisture, and temperature) as well as, the controlling meteorological variables, (photosynthetic photon flux density (PPFD)) were collected to derive relationships with the CO2 fluxes. Additionally, the energy and radiation budgets, air temperature and relative humidity were collected throughout the duration of the study period. An investigation of the spatial variability of soil moisture, depth to frost and soil temperature was examined to determine the spatial distribution and organisation of these parameters. Moran’s (I) test of spatial autocorrelation revealed that the study area displayed a limited degree of global spatial autocorrelation during long periods between, and directly following, precipitation events. Local tests of spatial autocorrelation demonstrated that prominent spatial patterns consisted of localised clusters and “hot-spots.” The determination of relative source contributions to the CO2 flux using a detailed footprint analysis scheme indicated that the degree of heterogeneity was large within the study area that no single vegetative community could be identified throughout the study period. However, groups of key species were adequately formulated in order to identify the flux contributions from these groupings. In general, seasonality played a strong role in dictating CO2 flux contributions from the vegetation groupings.

▼ The CRREL permafrost tunnel offers a unique opportunity to sample ice wedges in a climate-controlled environment, penetrating frozen silts which host massive ground ice that may record Dansgaard-Oeschger (D-O) and Heinrich Events. Ice wedges in the tunnel have been dated to approximately 36-22 ka (Hamilton et al., 1988), allowing the paleoclimate of the region to be reconstructed during MIS 3, when D-O and Heinrich events were documented in various other records. These climate cycles are rapid climate oscillations that have been recognized in records from the Arctic and subarctic, and suggest that climate can rapidly shift by 10°C over millennial scale times. I hypothesize that climate in the interior of Alaska varied with Heinrich events during MIS 3, and that these events were recorded as stable isotope variations in local permafrost ground ice. To test this hypothesis, I sampled an ice wedge in the permafrost tunnel for δ18O, δD and 14C to obtain a detailed climate record from central Alaska.
δ18O values from within the wedge display a gradual decrease of 5.95 / from the center toward the left edge, interpreted to reflect decreasing temperature, and is the same magnitude of decrease seen during the transition from the warm D-O interstadial 5 to the cold of Heinrich Event 3 in the NGRIP record in Greenland. Radiocarbon dates from within the wedge range from 28 - 37 cal kyr BP, and are interpreted here not to be the same age as the ice, but rather represent warm periods when sediment aggraded prior to ice wedge growth. These results suggest that D-O and Heinrich events impacted Late Pleistocene climate and ground ice in central Alaska.

▼ Mobile aquatic, aerial, and terrestrial robots open up
rich opportunities for
environmental monitoring. Sensors mounted on
a robot can be moved to take measurements in multiple locations,
allowing an effective spatial sampling density much higher than the
number of robots. In order to most effectively exploit mobile
robots in this manner, path planning methods which consider the
usefulness of measurements are needed. This thesis studies and
develops discrete planning algorithms for optimal usage of mobile
robots in
environmental monitoring applications. Specifically, we
address cases where a probabilistic model (e.g., a Gaussian
process) is used to predict a scalar field. In this context, the
usefulness of a set of measurements collected by a robot or team of
robots can be quantified as the expected reduction in entropy or
mean squared error, providing a well defined objective function for
the planner. We present path planning approaches which take
advantage of the characteristics of these objective functions to
efficiently plan optimal or near optimal paths for one or more
robots. ❧ This thesis makes the following contributions. First, we
present extensions to a submodular orienteering algorithm which
increases its usefulness for
environmental monitoring applications.
Specifically, we show how to handle temporally changing fields, and
how to efficiently incorporate sensors which take measurements
while the robot is moving. Second, we present a branch and bound
algorithm which adapts an upper bound from feature selection
literature to efficiently find the optimal solution to an
informative path planning problem. Finally, we provide results from
tests of the algorithms on real robotic problems, including ocean
monitoring using underwater gliders, and lake
monitoring using an
autonomous surface vehicle.

▼ In marine ecosystems, microalgae are important components as they transform large quantities of inorganic compounds into biomass thereby impacting environmental chemistry. Of particular relevance is phytoplankton’s sequestration of atmospheric CO2, a greenhouse gas, and nitrate, one cause of harmful algal blooms. On the other hand, microalgae sensitively respond to changes in their chemical environment, which initiates adaptations of their chemical composition and physical parameters. Analytical methodologies were developed in this study that utilize microalgae’s adaptation as a novel approach for in-situ environmental monitoring.To analyze the chemical composition and physical parameters of live microalgae cells (Nannochloropsis oculata), ATR FT-IR spectroscopy has been employed. From time-series IR spectra, the formation of biosediment can be monitored and it has been shown that nutrient availability has an observable impact. Since biosediment formation is governed by several biological parameters, this enables studies of the chemical environment’s impact on physical parameters of the cells.Moreover, the spectroscopic signatures of microalgae grown under 25 different CO2 and NO3- mixtures (200 – 600 ppm CO2, and 0.35 – 0.75 mM NO3-) have been used with a novel nonlinear modeling methodology coined ‘Predictor Surfaces’ that relates the nonlinear responses of the cells to their chemical environment. This approach was used to measure CO2 concentrations in the atmosphere above the algae cultures as well as dissolved nitrate concentrations within the growth medium simultaneously. The achieved precision of concentration predictions were a few percent of the measurement range. The effects of these pollutants on the formation of biomass were also determined and it was found that the cells’ growth rate was strongly, and nonlinearly, dependent on the availably of nitrate. In addition, it was found that algae cultures become more active when exposed to a decrease in atmospheric carbon dioxide levels. This methodology will open new approaches to study the link between concentration levels of anthropogenic pollutants within an ecosystem and their biological impacts.

▼ Water is the essence of life and an important nutrient for every living thing. Therefore, ninety six novel planar electromagnetic sensors based on the combination of meander sensor and interdigital sensor have been designed, fabricated, and tested for the application of water quality
monitoring. Experiments were conducted to obtain the impedance characterization for each sensor, and the results were used to estimate the important parameters that influence the performance of the sensors based on the equivalent electrical circuits. The best sensors were selected based on the design with the highest electrical parameters (total effective capacitance and effective inductance). Intensive modelling and simulation of the selected best sensors are also discussed where the results were compared with the simulation results. Furthermore, the best sensors have been tested to detect nitrates contamination in distilled water using sodium nitrate (NaNO3) and ammonium nitrate (NH4NO3) solutions with different concentrations. The sensor that consists of the series combinations of spiral meander planar sensor (with five turns) with the interdigital sensor (with large negative electrode): SECS22_1 is the best sensor to detect the presence of nitrate added into distilled water and can estimate the concentration level. Furthermore, the sensor was tested with various kinds of prepared samples and natural water samples taken from natural sources around New Zealand. The outcomes have shown a very good correlation of contamination level, translated from the qualitative and quantitative results. Using the SECS22_1 sensor, a method to estimate nitrate contamination in natural water sources using Independent Component Analysis (ICA) has been explained and demonstrated. This model can accurately estimate nitrate in a natural water source as shown by the results. A low-cost system has been developed based on SECS22_1, a microcontroller, a waveform circuit, signal conditioning circuits, and LabView. The results from the experiment have shown the low-cost system has the potential to be used as a tool for nitrate detection and water sources quality
monitoring in remote places such as farms. Finally, the work and improvement for future consideration are also discussed in this research.

▼ Over the past two decades, biomarker responses have been increasingly used within
environmental monitoring programmes to provide information on the adverse effects of contaminants. Evidence for the ecological relevance of biomarkers and large-scale assessments of their applicability as sensitive indicators of contaminant stress in the field are rare. This thesis investigates the use of biomarkers as indicators of biological effects from anthropogenic pollution in marine filter feeding organisms. I focus particularly on the ecological relevance and consistency of biomarker responses over large spatial scales in the presence of multiple stressors, and their potential application for the improved
monitoring of current ecological threats; re-suspended contaminated sediments and industrial discharge associated with oil and gas drilling activities. Using a series of laboratory and field experiments, cellular biomarkers were developed and their utility evaluated in two organisms; the Sydney rock oyster Saccostrea glomerata and a deep sea sponge Geodia barretti. My research established a strong relationship between lysosomal membrane stability in oysters, reproductive effects and contaminant exposure associated with re-suspended sediments. In the Sydney rock oyster, the relationships between lysosomal membrane stability and contaminant exposure were consistent across multiple estuaries. In contrast, measurements of other cellular biomarkers, lipid peroxidation and glutathione, were inconsistent and of no clear ecological relevance. The application of cellular biomarkers for distinguishing the effects associated with re-suspended contaminated sediments and drilling discharge, confirmed that suspended contaminants are a potential source of exposure and threat to filter feeding organisms. Re-suspended contaminated sediments and a major component of drilling discharge, barite, were toxic to oysters and sponges respectively. The observed cellular toxicity increased with an increase in total suspended solids (TSS), however increasing the amount of clean TSS had no impact on cellular responses in these organisms.In summary, this is the first study to evaluate the consistency and ecological relevance of cellular biomarker responses to anthropogenic contaminants in the Sydney rock oyster, Saccostrea glomerata and deep sea sponge, Geodia barretti. My research has highlighted that lysosomal membrane stability responses in these organisms may provide a very useful line of evidence for both exposure and effects in
environmental monitoring programs.

▼ Water management and irrigation practices are persistent challenges for many agricultural systems. Changing seasonal and weather patterns impose a greater need for understanding crop deficiencies and excesses (e.g. water, sunlight, nutrients) for optimal growth while allocating proper resources for prompt response. The wild blueberry industry is at heightened susceptibility due to its unique growing conditions and uncultivated nature. Early detection of stress in agricultural fields can prompt management responses to mitigate detrimental conditions including drought and disease. Remote sensing has provided timely and reliable information covering large spatial extents, while novel applications in hyperspectral data and imaging spectroscopy have shown potential in early stress detection. We assess airborne spectral data accompanied by ground sampled water potential over three developmental stages of wild blueberries to accurately detect water content. Airborne scans of spectral data were collected three times throughout the 2019 summer in Deblois, Maine. Data were collected over two adjacent fields, one irrigated and one nonirrigated. Ground sampled data were collected in tandem to the UAV collection. The ground sampled data over the irrigated and non-irrigated fields guided digital sampling from the imagery to act as training for our models. Using methods in machine learning and statistical analysis, we related hyperspectral reflectance measurements to different water potential levels in blueberry plant leaves to decipher vegetation signals both spatially and temporally through utilizing the capacity of imaging spectroscopy. Models were developed to determine irrigation status and water potential. Seven models were assessed in this study with four used to process six hyperspectral cube images for analysis. These images were classified as irrigated or non-irrigated and estimated water potential levels. Our global water potential model had an R2 of 0.62. Models for the water potential predictions were verified with a validation dataset. Forest insect and disease pests have a significant impact on the well-being of individual trees and forest stands, affecting ecosystem processes and potentially human health. Dispersing through 35 states within only 17 years (USDA, 2020), the effect of emerald ash borer (Agrilus Planipennis Fairmaire) (EAB) in the United States has been particularly severe and devastating. Early detection of stress in forests can prompt management responses to mitigate detrimental conditions including drought and disease as well as pest outbreaks. Remote sensing has provided timely and reliable information covering large spatial extents, while novel applications in hyperspectral data and imaging spectroscopy have shown potential in early stress detection. We build on previous work by assessing airborne spectral data, and health classifications of EAB infested ash trees in aims to accurately detect stress. Airborne scans of spectral data were collected within three days in late July 2019 over three…

▼ Antimony (Sb) is a toxin that can be found in high concentrations in the soil due to anthropogenic sources. Antimony exists in soil as Sb(V) in the monovalent antimonate hydroxyanion. The adsorption mechanisms of Sb(V) are not well-characterized. The objective of this study was to further elucidate Sb(V) adsorption mechanisms by examining the impact of adsorption on surface charging characteristics of gibbsite, goethite, birnessite, and kaolinite. Also examined was Sb(V), SO
4 [sulfate], and PO
4 [phosphate] adsorption by birnessite. Electrophoretic mobility and potentiometric titrations were employed to examine the ζ-potential [zeta-potential] and net proton surface charge density as a function of pH and ionic strength, and in the presence or absence of adsorbed Sb(V), phosphate, or sulfate. Competitive batch adsorption studies were performed to examine Sb(V), SO
4, and PO
4 adsorption as a function of pH, ionic strength, and competitive environment. Results suggest that Sb(V) participates in inner-sphere adsorption by gibbsite, goethite, and kaolinite in acidic conditions, PO
4 participates in inner-sphere adsorption by gibbsite, goethite and kaolinite in the pH range studied, and that SO
4 participates in inner- and outer-sphere adsorption by gibbsite, goethite, and kaolinite with the former mechanisms becoming more important in acidic conditions. Adsorption of Sb(V) and PO
4 by birnessite had little impact on the surface charge characteristics indicating outer-sphere adsorption. Batch adsorption edge studies showed Sb(V) and PO
4 retention to be dependent on pH and ionic strength, supporting electrostatic adsorption mechanisms. Batch adsorption studies showed SO
4 was not adsorbed by birnessite in the pH 3 to 11 range. The adsorption data was modeled using FITEQL 4.0 and the diffuse layer model (DLM). The DLM adequately described Sb(V) and PO
4 adsorption by birnessite using electrostatic surface complexes.

▼ Hydrogen Sulfide is a corrosive, odorous, and hazardous gas that can cause issues for wastewater collection systems and treatment plants. When evaluating hydrogen sulfide concentrations it is important to consider the source, odor causing mechanism, and its level of toxicity. In this study, continuous hydrogen sulfide
monitoring was performed for 8 locations within the New Orleans East Bank Wastewater Treatment Plant for a span of 5 months. Hot spots within the plant are located and data analysis is performed based on daily and hourly averages of hydrogen sulfide concentrations. The data was configured to show peak hydrogen sulfide concentrations at specific time intervals throughout the day.
Advisors/Committee Members: Kura, Bhaskar, La Motta, Enrique, McCorquodale, Alex.
Subjects/Keywords: wastewater treatment, hydrogen sulfide, odor control, monitoring; Environmental Engineering; Environmental Health and Protection; Environmental Monitoring

▼ This thesis examined the use of acoustic sensors for monitoring avian biodiversity. Acoustic sensors have the potential to significantly increase the spatial and temporal scale of ecological observations, however acoustic recordings of the environment can be opaque and complex. This thesis developed methods for analysing large volumes of acoustic data to maximise the detection of bird species, and compared the results of acoustic sensor biodiversity surveys with traditional bird survey techniques.

▼ Environmental Monitoring Systems and Sensors systems have increased in importance over the years. However, increases in measurement points mean increases in installation and maintenance cost. Not to mention, the measurement points once they have been built and installed, can be tedious to relocate in the future. Therefore, the purpose of this Masters thesis is to present a project called “A Wi-Fi based Smart Wireless Sensor Network for an Agricultural Environment” which is capable of intelligently monitoring agricultural conditions in a pre-programmed manner. The proposed system consists of three stations: Sensor Node, Router, and Server. To allow for better monitoring of the climate condition in an agricultural environment such as field or greenhouse, the sensor station is equipped with several sensor elements such as Temperature, humidity, light, air pressure, soil moisture and water level. In addition investigation was performed in order to integrate a novel planar electromagnetic sensor for nitrate detection. The communication between the sensor node and the server is achieved via 802.11g wireless modules.
The overall system architecture shows advantages in cost, size, flexibility and power. It is believed that the outcomes of the project allow for opportunities to perform further research and development of a Wi-Fi based Wireless Sensor Network that is a portable and flexible type of sensing system for an Agricultural Environment.

▼ Advances in farming technology, and the variety of modern agricultural practices, have the
potential to reduce, maintain or improve biodiversity in an agricultural landscape.
Environmentally sensitive farming systems are becoming more important on a local level, as
climate change, declining biodiversity and habitat fragmentation impact the environment at a
landscape scale.
Invertebrates are important components of an agricultural landscape, playing numerous roles
including pest control, plant protection, pollination, and carbon cycling. They are also an
important food source for many reptiles, birds, mammals and other insects, making them a
key component of the food chain. Ants in particular are useful tools in biodiversity
monitoring as they are abundant in both disturbed and intact habitats, and their many
functional groups help to illustrate their community structure at a given point in time. For
these reasons, they can be used to demonstrate the short and long term impacts of land
management in various environments, including rehabilitated mine sites, fire affected regions,
and agricultural landscapes.
Conducted on working farms, this study looked specifically at insect in the agricultural
landscape, using 10 sheep pastures which have been restored with eucalypt plantings.
Looking at species richness, relative abundance, and community structure, this study assessed
the ant and beetle communities in these plantings and compares these to pasture control sites
and nearby remnant woodland patch control sites. The influences of elevation, ground cover,
soil clay, patch size, and age of planting were tested using regression analyses. It was found
that leaf litter cover and weediness have a significant influence on invertebrate recolonisation
of a restoration planting. Elevation was negatively correlated for all ant activity, whilst the
age of the planting was positively correlated with ant abundance and species richness.
This study shows that ants can be useful monitoring tools in agricultural landscapes, and
specifically useful when assessing the effectiveness of on-farm restoration plantings. It also
provides a better understanding of the influence of environmental variables on a restoration
planting, which in turn can help inform land management decisions.

▼ Prior to restoration, Braddock Bay was an open embayment wetland on the southern coast of Lake Ontario, and it is part of the Rochester Embayment Great Lakes Area of Concern (AoC). Braddock Bay was partially protected by two spits that are remnants of the protective barrier beach that has slowly been eroded over time. Without the barrier to protect the shoreline within the bay, the coastal wetland was severely impacted by wave action from Lake Ontario, leading to loss of 43 hectares of wetland. The erosion of the barrier was facilitated by water-level regulations implemented in the late 1950s. A further consequence of water-level regulation was the loss of diversity, as the lack of periodic low water levels resulted in a cattail monoculture and the loss of sedge/grass meadow habitat. Braddock Bay is being restored by the United States Army Corps of Engineers. The plan called for the following: restoration of a portion of existing cattail-dominated wetland by cutting cattails in August (when storage carbohydrates in rhizomes are minimized) and herbicide treatment of new stems; channeling and potholing to improve wildlife access to the wetland; the re-creation of the historical barrier beach using rubble-mound and sand; and the creation of spoil mounds along the channels and potholes to increase the elevation in these areas and discourage the growth of cattail while supporting the growth of sedge/grass meadow species. Two years of data collection were performed following construction activities in 2016. Preliminary surveys showed an increase in an invasive species of concern (purple loosestrife) from year 1 to year 2 across the restoration site. A decrease in cattail across the years was observed in the cattail treatment areas, along with a slight decrease of
Typha found in the sedge/grass meadow and spoil mound habitats. Based on this
monitoring, construction standards set for the restoration must be met, and adaptive management must occur throughout the project timeline for restorations to succeed. Site-level weighted mean C metrics are recommended for future floristic analyses based on an observed species richness influence on FQAI.

▼ Sediments in McMurdo Sound, Antarctica have been altered through contamination derived from McMurdo Station. Long-term monitoring of benthic communities provides a basis for assessment of impacts located near known sources of historic pollution. The objectives of the present study are to determine if any changes in benthic community abundance, biomass, and diversity occurred over time and if the change was due to contamination effects by comparing benthic communities between polluted and reference stations. Benthic cores were collected from either three or four transects at depths of 12, 24, and 36 meters during the austral summers of 2000 and 2003 to 2012. Transects included: Winter Quarters Bay and the Sewage Outfall, located near known sources of historic pollution; and Intake Jetty and Cape Armitage that are non-polluted, reference transects. Macrofauna metrics and a Benthic Index of Biological Integrity (BIBI) were used to test for spatial and temporal changes in macrofaunal communities. Disturbance-related spatial differences were detected using BIBI-ranks at Winter Quarters Bay indicating pollution effects in benthic communities at that location. Benthic community composition changed among all stations, disturbed and reference, over time. Therefore, the observed shifts in macrofaunal communities can primarily be attributed to natural processes rather than changes from contamination effects.

▼ Nitrogen and phosphorus are the most common limiting nutrients for biological activity in freshwater ecosystems. Applying inorganic nitrogen fertilizer has increased crop productivity but caused excess nitrogen inputs to the hydrosphere. Nitrate contamination is a worldwide environmental problem. The fate of nitrogen in ecosystems is variable based on land type and hydrogeological interactions. Excess nitrogen can be retained in soils, sequestered in stream organisms, denitrified or transported downstream. The goals of this study were to monitor nitrogen concentrations in Pine Draw, Turnbull National Wildlife Refuge (TNWR), Washington, U.S.A., and to determine the source of nitrogen loading. Pine Draw is unique because it’s located in the channeled scablands and has minimal anthropogenic impacts but has experienced excess nutrients for at least 20 years. Symptoms of nutrient loading observed on TNWR are an overabundance of primary producers, decreased biological diversity, extensive algal blooms, low dissolved oxygen, episodic anoxia, loss of vascular plant life and fish kills. I sampled nine surface water, three groundwater inputs on Pine Draw and three surface water sites on Philleo drainage monthly from October 2016 to October 2017. I documented nitrate+nitrite (NO3-N), ammonium (NH4+-N) and phosphate (PO43-) concentrations as well as specific conductance, conductivity, dissolved oxygen, temperature, pH and discharge in both watersheds for the duration of the sampling period. We used stable isotope ratios of oxygen and nitrogen in nitrate to determine that the source of nitrogen to Philleo drainage, groundwater and Pine Draw was a combination of ammonium fertilizer and soil nitrate varying seasonally based on water source.
