▼ Direct and indirect effects resulting from predator-prey interactions can affect ecosystem function. Understanding these relationships has been a central focus of community ecology for more than 50 years. However, human impacts on ecosystems during this period may have altered these relationships. Here I assess important impacts of ocean acidification, ocean warming, and land-use change on the predator-prey relationships between the oyster, Crassostrea virginica, and several species of crab. Calcifying marine taxa have been shown to respond differently to ocean acidification. Bivalves typically show more severe reductions in net calcification than the decapods that prey on them. This study found C. virginica and the crab, Panopeus herbstii, had generally reduced net calcification with decreasing calcite saturation states. However, both species maintained positive net calcification in undersaturated calcite conditions. In experiments, acidification significantly reduced the consumption rate of C. virginica by P. herbstii. Differences in net calcification did not explain consumption rates, rather behavioral change, manifest as reduced prey handling and persistence of the predator, were the likely cause. Ocean warming is driving pole-ward shifts in the ranges of numerous species, leading to the formation of novel communities. The stone crab, Menippe mercenaria, is one such species, but little is known about its ecology and thus its like impact on ecosystems in its new range. My data suggest that crabs between 70 and 90 mm are likely to have the largest effect on intertidal oyster reefs due to higher consumption rates and an ability to consume all sizes of oyster. Smaller crabs are limited by the size of oyster they can consume and larger crabs demonstrated less interest in oyster as a prey item. Land-use change and accompanying habitat loss has driven increased interest in estuarine ecosystem services and functions. C. virginica relies on filtration to provide its outsized contribution to estuarine ecosystem function and services. Other species of bivalves reduce their filtration rates to reduce their predation exposure. However, C. virginica showed no such behavior in the presence of two common crab predators. This research highlights the dynamism of predator-prey relationships and their important role in current and future ecosystem function.

▼ Species interactions, including competition and predation, can drive the development of biogenic habitats across environmental stress gradients. Using the Eastern oyster (Crassostrea virginica) as a model, my dissertation investigates how competition and predation limit the distribution of euhaline oyster reefs to the intertidal zone. In the field (Chapter 1) I examined how competition with epibiota, which compete for space in the subtidal and low-intertidal zones, affects juvenile oyster growth and survival. I also tested if competition between oysters and epibiota diminishes with increasing oyster body size. Removing epibiota increased oyster survival, especially in the lower-tidal-exposure treatments where epibiota cover is high. Larger oyster body size resulted in significantly higher oyster growth than smaller body sizes at lower tidal exposures. Following competition with summer epibiotic communities, oysters are covered by macroalgae in the winter and spring. In Chapter 2, I quantified baseline macroalgal dynamics and explored the effects on oyster fitness. I found that macroalgal cover is controlled mainly by abiotic forcing and does not reduce oyster growth or survival. Predation may be another mechanism that causes oyster mortality the subtidal, but the settlement and predation rates may vary across different scales. I examined how oyster settlement and predation of oysters are affected by landscape setting, aerial exposure, and structural complexity (Chapter 3). Oyster settlement increased with inundation time and isolated reefs had greater settlement and adult densities than saltmarsh-fringing reefs. Oyster survivorship at low complexity was greater on isolated reefs than saltmarsh-fringing reefs and predation by nekton increased with increasing inundation. At high complexity, predation rates by mud crabs had highest at intermediate aerial exposures, likely due to an interaction of predator density and foraging behavior. Results from my dissertation indicate that predation and competition reduce juvenile oyster survival at low environmental stress, but net result of settlement and post-settlement processes is dependent on reef complexity and landscape setting. Restoring reefs on isolated sandflats immediately before oyster settlement in the lower-mid-intertidal will minimize competition with epibiota and predation. Maximizing reef growth by reducing species interactions will increase reef complexity and further increase survivorship from predation. Advisors/Committee Members: Brodeur, Michelle, Fodrie, F.

▼ Temperature can affect population and community level processes, via strong and predictable effects on individual metabolism. Metabolic Scaling Theory (MST) 1) describes how individual metabolic rates scale with temperature, and 2) generates mechanistic predictions based on how this response to temperature variation will drive ecological pattern and process. For example, temperature can influence trophic interactions via differential metabolic scaling of predator and prey metabolic rates. More specifically, metabolic theory and experiments indicate warmer temperatures can increase the top-down effects of herbivores on plant biomass, resulting in depleted standing plant biomass. Yet there are few studies that have tested metabolic scaling theory in the ocean across natural, in situ, environmental gradients. The Galapagos Islands is the ideal system for testing metabolic scaling theory in situ because the Archipelago is at the center of several different oceanographic currents (tropical, subtropical and upwelled water), resulting in enormous variation in water temperature (11°C - 31°C). Upwelling is the wind-driven process of cold, nutrient-rich subsurface water replacing warm, nutrient-poor surface water. Also, even though community composition differs across the Archipelago due to oceanographic conditions, there is a suite of organisms that are present across the Islands throughout the year. For my doctoral dissertation research, I quantified benthic community patterns across the Islands and related community composition and biomass to temperature. I also tested metabolic scaling theory in the Galapagos Islands via lab experiments, in situ grazing assays, and a long-term exclusion experiment. Further, to examine the generality of temperature variation in upwelling systems, I analyzed in situ temperature data from five upwelling regions and examined differences in thermal regimes between the regions. I then related this temperature variation to local grazer-algal interactions. Overall, my findings provide evidence for a mechanistic link between temperature and grazing rates and suggest temperature-mediated herbivory could be important in influencing benthic community patterns in upwelling systems.

▼ In response to the degradation of coastal environments and their associated habitats, managers and policy makers have looked to utilize population dynamics and, more specifically, connectivity (i.e., import and export of larvae, juveniles, and adults) in order to rebuild stocks. As the majority of population bottlenecks are thought to result from critical periods experienced in earlier life stages, it is particularly important to discern movement patters during larval and juvenile stages. This study used two estuarine-associated model organisms, the Eastern oyster and the black sea bass, to examine connectivity at the larval and juvenile stages, respectively. A requisite to tracking larval dispersal of the Eastern oyster was to explore the utility of geochemical tagging methods within our study system, the Pamlico Sound. Strong environmental (e.g., temperature and salinity) gradients were present over regional (~ 35 x 15 km quadrants) scales and both larval and settler shells were able to generate distinct, multi-elemental signatures between putative natal and settlement sites. These methods were then applied, with a combination of larval outplanting techniques (i.e., stationary moorings and floating surface drifters), to show that larval dispersal is single-source driven, generally follows wind-driven currents, and leads to high amounts of self-recruitment. However, dispersal pathways are not uniform across the Sound and seasonal and annual dispersal patterns can be highly variable. Geochemical tagging of black sea bass showed that estuarine nurseries, such as oyster reefs, contribute over 89% of the juvenile black sea bass to the adult stock; however, there is significant annual variation in contribution. The role of estuarine habitats becomes even more complex for the protogynous black sea bass, as fish exhibited carry-over effects (COEs) related to nursery habitats: juveniles that utilized estuarine nurseries transitioned from female to male six months earlier than juveniles that utilized offshore nurseries. This dissertation provides substantial support for the implementation of habitat-based management plans rather than single-species management practices, which cannot account for seasonal and annual variation inherent in dispersal pathways or variable reproductive (and dispersal) potential among subpopulations.

As sea level continues to rise, natural marshes can be sustained by transgression landward. The presence of a bulkhead, rip-rap revetment, or hybrid of those two, however, prevents transgression by fixing the location of the upper marsh. Simultaneously, as sea levels rise, wind-driven waves from storms and boat wakes erode the lower edge of the marsh, inducing slumping of the marsh platform into the sound. So marsh width, and thereby area, is declining in the squeeze between the fixed bulkhead and the rising waters, ultimately leading to its disappearance. We quantify and compare use by nekton (fish and crustaceans) and birds of marshes in front of bulkheads but differing in width from bulkhead to shoreline edge, and use width as an inverse proxy for time since marsh establishment to infer temporal habitat changes. Within three geographic areas of North Carolina, meteorologically driven Pamlico Sound in Kitty Hawk Bay, a strongly astronomically driven southern region along the Intracoastal Waterway around Wilmington, and a central region in Bogue Sound with mixed tidal forcing, we established five bulkheaded marsh sites with varying marsh widths of 0 to 40 m plus 1 non-bulkheaded marsh. Intensity of marsh use (abundance in fyke nets) for both fish and crustaceans exhibited similar responses of linear increase with marsh width over three geographic areas, two seasons, and two years. This repeated pattern implies that nekton use in marshes below shoreline stabilization structures declines over time as marsh width is reduced. Nekton density per unit marsh area sharply declined with increasing marsh width, implying that even the smallest marsh remnants have important habitat functions and deserve continued protection. Community compositions of birds using the shorelines varied significantly among the three regions, which differ dramatically in tidal excursion. We conclude that coastal marsh condition influences important aspects of bird use and marsh itself is critical to sustaining a diversity of bird guilds. The continued installation of bulkheads will promote marsh loss as sea level rises, ultimately degrading avian ecosystem services of coastal marshes.

▼ Habitat describes the place where food is found, refuge is sought, or reproduction occurs, and is therefore a fundamental resource for organisms. To help reverse the consequences of global loss of biogenic habitats, ecologists and managers are assessing how the structure and spatial components of habitat within the landscape can restore lost ecosystem functions and services. Building on these concepts, I attempt to identify how the amount, context (inter-habitat connectivity), orientation (amount of edge habitat), and species composition of biogenic habitat(s) influences faunal habitat-use. By manipulating habitat amount (Ch. 1), I determined the strength of habitat limitation for estuarine fauna depends on the species-identity and life-stage and that overall declines in structured habitats in estuaries may reduce secondary production. In Ch. 2, I restored oyster reefs along different salt marsh geomorphologies to test if this landscape context affects restoration trajectories as well as fauna habitat-use. I found that oyster reef restoration in salt marsh creeks, compared to other shorelines, could increase oyster production. Regardless of landscape context, restoring reefs near salt marsh had little impact on local densities of fauna. To determine the response of flora and fauna to habitat edges (Ch. 3), I conducted a meta-analysis of 211 studies and found marine and terrestrial edges increased fauna foraging and mortality, but had no effect on fauna recruitment. However, fauna density increased in marine edges and decreased in terrestrial edges. In Ch. 4, I assessed how species composition of biogenic habitat affects estuarine communities and found no difference in fauna density, fauna community composition, or the movement of fishes between seagrass sites dominated by eelgrass and shoalgrass. Since we did not find increases in fauna density or movement of fishes to shoalgrass after the seasonal loss of eelgrass, we predict shoalgrass may not serve as a habitat refuge for fauna, but that it still provides better habitat than mudflats. Overall, these results suggest that habitat amount/availability, as well as the relative amount of edge habitat, have large effects on fauna habitat-use and distributions, where as the impact of landscape context and the species composition of biogenic habitat(s) were less clear.
