Degradation Rates of Native versus Exotic Leaves in a Tributary of the Yellow River in Georgia

Abstract: Forested aquatic streams depend heavily on forest canopy input. This input is a primary resource for the macroinvertebrate fauna. As a result, changes in the canopy impact the aquatic ecosystem. The focus of this study was to identify leaf degradation rates to determine resource availability for invertebrate communities. Specifically, leaf degradation rates were determined for oak, poplar, maple and kudzu. Oak, poplar, and maple are established stream canopy vegetation while kudzu is an invasive species.

“…Invasions of riparian ecosystems by exotic species could drive substantial changes to nutrient release, as properties of alien species may differ markedly to native analogues [36,37]. In this study, whilst we demonstrated that interspecific differences in leaf litter decomposition are important for allochthonous nutrient dynamics within freshwater environments, these differences were not conserved and thus generalizable according to alien-native statuses.…”

“…A colonização microbiana no material detrital pode ser afetada por características físicas e químicas do detrito, que influenciam diretamente na taxa de decomposição (ALVIN et al, 2015;GOMES et al, 2015a) e também pela composição da vegetação riparia (KOMINOSKI et al, 2011;FERREIRA et al, 2016). A substituição de espécies nativas da vegetação ripária por espécies exóticas pode influenciar na colonização fúngica e na taxa de decomposição dos detritos foliares (BOEYRO et al 2012;GOMES et al, 2016;GEORGE et al, 2017…”
