Litter Breakdown And Benthic Invertebrate Detritivores From A Hydrologically Restored Stream
<p>The breakdown of coarse forms of detritus into finer forms is an ecosystem function of forested headwater streams. Many factors influence the rate of litter decay, but there is a lack of research on how stream restorations, that aim to restore hydrologic functions, influence litter breakdown. …

Effect of a Water Treatment BMP on Nutrient Spiraling and Leaf Litter Breakdown in an Urban Stream
… of this BMP on nutrient spiraling and leaf litter decomposition in a 2 km stretch of Weracoba Creek. I hypothesized the BMP would (1) reduce leaf mass loss over time and (2) interfere with nutrient concentrations and uptake lengths. I characterized leaf litter decomposition using tulip tree …

Factors Influencing the Functional Roles of Crayfish in Stream Ecosystems
… many invertebrate taxa and also accelerated leaf litter breakdown rates within enclosures. In times and places where they are abundant, juvenile crayfish may strongly modify ecosystem processes and benthic invertebrate assemblages in streams.

The effects of the invasive exotic Chinese tallow tree (Triadica sebifera) on amphibians and aquatic invertebrates
… dissertation addresses the question of how leaf litter from trees affects animals that live in aquatic environments, with an emphasis on the effect of Chinese tallow (Triadica sebifera) leaf litter on anuran larvae (i.e., frog tadpoles). This question is important to our understanding of how …

Interactive Effects of Cover Crops, Invertebrate Communities and Soil Health in Corn Production Systems
… characteristics, soil health metrics, relative litter degradation rates in the presence and absence of invertebrates, yield, and profitability were assessed. Relationships among these metrics were examined, and trends between systems were also analyzed. Regenerative systems had reduced pest …

Linking Heterotrophic Metabolism and Nutrient Uptake in Headwater Streams
… of a southern Appalachian stream. We measured litter input, organic matter standing crops, litter respiration rates and nitrate demand several times during the course of decomposition. There was a strong relationship between leaf standing crop and nitrate uptake efficiency across dates with …

Effects of leaf litter diversity on nutrients and mosquito communities in Neotropical artificial tree holes
… and Tectona grandis) to test the effects of leaf litter species composition and richness on invertebrate aquatic communities in Gamboa, Panama. We quantified macroinvertbrate species richness and abundances, leaf litter mass loss, and dissolved carbon to nitrogen ratios (C:N) after 4 weeks. We …
