Benthic Macroinvertebrates of Bull Run Creek: A Pre-Restoration Baseline
نویسندگان
چکیده
In North America, disturbed riparian zones have had a deleterious effect on the life cycles of anadromous fish, especially commercially and culturally important salmon steelhead. The result has been significant reduction in numbers average size these fish. Tributaries John Day River are spawning waters for western populations National Forest Service Confederated Tribes Umatilla Indian Reservation cooperating to restore floodplains number headwater tributaries. Herein we conducted pre-restoration study macroinvertebrates basic water quality parameters one locations central Oregon, Bull Run Creek. Results turbidity, pH, dissolved Oxygen, temperature determinations indicate that overall is good, benthic macroinvertebrate sampling yielded sensitive organisms, including members Chloroperlidae, Peltoperlidae, Ryachophilidae, Odontoceridae, Brachycentridae. At all sites, chironomid larvae (non-biting midge) dominated assemblages. EPT Index suggests Creek ranges from fair excellent terms its ability support species. Sorensen’s Similarity Coefficient indicates varying degrees shared diversity between Shannon’s entropy calculations suggest moderate low species at reference site nearby Boundary Overall, this condition it should benefit significantly restoration efforts.

Microplastic Effect Thresholds for Freshwater Benthic Macroinvertebrates
Now that microplastics have been detected in lakes, rivers, and estuaries all over the globe, evaluating their effects on biota has become an urgent research priority. This is the first study that aims at determining the effect thresholds for a battery of six freshwater benthic macroinvertebrates with different species traits, using a wide range of microplastic concentrations. Standardized 28 d...
متن کاملBenthic macroinvertebrates of a tropical lake: Lake Caçó, MA, Brazil.
Benthic communities are highly relevant in the study of aquatic ecosystems, both for their role in the functioning of the ecosystem and also as markers or indicators of paleo-conditions. Their distribution, as in other communities, is conditioned by abiotic and biotic factors and to their interactions, which determine the structure of the community that is established. The aim of this study was...
متن کاملEcological quality assessment of stream ecosystems using benthic macroinvertebrates
In this study, we applied the SOM for ecological assessment using benthic macroinvertebrates in aquatic ecosystem. First, Chapter I, SOM was utilized to extract information from complex data of environmental variables and benthic macroinvertebrate communities residing in different micro-habitats. Although the sampling was carried out in a limited area, the patterns of environmental variables re...
