Soil Metabolite Succession In Vertebrate Decomposition Impacted Soils, Jennifer Kate Baer
Soil Metabolite Succession In Vertebrate Decomposition Impacted Soils, Jennifer Kate Baer
Masters Theses
Vertebrate decomposition results in a pulse of critical nutrients such as nitrogen, carbon, and phosphorus into the environment creating a ‘hotspot’ immediately surrounding the carcass. While many decomposition studies have investigated vertebrate decomposition focused on the carcass itself, fewer studies have focused on the impacts of decomposition products on soils. Gaining a greater understanding of soil processes during decomposition could not only aid in better understanding soil biological activities but could also lead to new insights in nutrient cycling in the environment. The assemblage of soil metabolites, also known as the soil metabolome, exposes not only the breakdown products of …
Filamentous Green Algae (Cladophora Glomerata) In Near Shore Lake Ontario: An Investigation Of Tissue And Water Nutrient Dynamics Through A Period Of Growth And Decomposition., James L. Wagner Jr
Filamentous Green Algae (Cladophora Glomerata) In Near Shore Lake Ontario: An Investigation Of Tissue And Water Nutrient Dynamics Through A Period Of Growth And Decomposition., James L. Wagner Jr
Biology Theses
Cladophora glomerata, a filamentous green alga abundant in the Laurentian Great Lakes, has long been considered a nuisance throughout the region. Previous phosphorus (P) abatement practices and legislation successfully reduced the abundance of the algae, but with the introduction of dreissenid mussels, a resurgence has been observed. Though there is substantial literature and modeling of the growth cycle of Cladophora, relatively little research has been dedicated to the decomposition stage of the algae, a period which may contribute to a substantial influx of nutrients to near-shore environmental regions. By first examining a period of in-situ growth within Lake …
Effects Of Forest Restoration On The Recovery Of Dead Wood, Associated Arthropods, And Insect-Mediated Wood Decomposition, Estefania Fernandez Barrancos
Effects Of Forest Restoration On The Recovery Of Dead Wood, Associated Arthropods, And Insect-Mediated Wood Decomposition, Estefania Fernandez Barrancos
Dissertations
Dead wood represents 8% of terrestrial carbon stocks and is an important source of habitat and food for decomposer and non-decomposer arthropods. However, anthropogenic disturbance reduces the amount of dead wood, putting at risk the presence of a habitat that is essential for many arthropods and other organisms that rely on it for food and shelter. Forest restoration aims to assist the recovery of ecosystems that have been damaged or destroyed and could be a means to recover both dead wood and its associated arthropod communities. This doctoral dissertation lies at the intersection of climate change, biodiversity loss and ecological …
