1. Kennedy, Emmalisa. Effects of control of the invasive plant, <i>Phragmites australis</i>, on microbes and invertebrates in detritus.

Degree: MS, College of Arts and Sciences / Department of Biological Sciences, 2008, Kent State University

Emergent plant litter is a major source of energy and carbon in wetland food webs. Detritus and the associated microbes are eaten by invertebrates, thereby transferring the carbon and energy to higher trophic levels. Monocultures of an invasive common reed, <i>Phragmites australis</i>, can alter wetland food webs and decrease native plant diversity. Therefore, stands are often controlled by cutting and/or herbiciding. The processes of decomposition were studied using leaves of herbicided and non-herbicided <i>Phragmites</i> and non-herbicided native wool grass, <i>Scirpus cyperinus</i>, using litterbags in wetland mesocosms. Leaf mass loss, percent organic content, C:N ratios, fungal biomass, bacterial numbers and biomass, and invertebrate community composition (total numbers, abundance of functional feeding groups and dominant taxa, richness) were examined on ten dates over the course of 293 days. There were no differences in invertebrate communities or most chemical characteristics between herbicided and non-herbicided <i>Phragmites</i> leaf litter, and both litter types decayed at similar rates (0.0047 <i>k</i>-1 and 0.0051 <i>k</i>-1, respectively). However, herbicided <i>Phragmites</i> litter had higher fungal and bacterial biomass than non-herbicided <i>Phragmites</i> litter. In contrast, <i>Scirpus</i> litter decayed much more slowly (0.0029 <i>k</i>-1) and had higher organic content remaining than either <i>Phragmites</i> litter. At the end of the study, over 44% of the <i>Scirpus</i> litter remained but only 13 - 14% of <i>Phragmites</i> litter remained. Significant differences were found in microbial communities between <i>Scirpus</i> and <i>Phragmites</i> litter, where <i>Phragmites</i> litter generally had higher fungal and bacterial biomass. Invertebrate richness was also higher on <i>Phragmites</i> than <i>Scirpus</i> litter. Furthermore, there were non-significant trends that total invertebrates, detritivores and collector-gatherers were higher on <i>Phragmites</i> than <i>Scirpus</i> litter by the last sampling date (25 May 2007). Principle components analysis also showed high positive correlation between fungal biomass and invertebrate richness. Collectively, these results indicate that the use of herbicide to control <i>Phragmites</i> may not significantly alter decomposition processes or the associated invertebrate community compared to non-herbicided <i>Phragmites</i> stands. Furthermore, although dense stands of the invasive <i>Phragmites</i> can decrease overall wetland plant diversity, numbers and diversity of detritivorous invertebrates on the litter, invertebrates on <i>Phragmites</i> leaf litter may be as high as those occurring on native plants that have slow decay rates.
