The deep-sea benthic community at the Porcupine Abyssal Plain (NE Atlantic) is a highly food limited system. The annual input of sedimenting phytodetritus, which reaches the sea floor around May/June, is the major input of energy. The relative trophic position of the most abundant components of the benthos (90 species or higher taxonomic groups), including meiofaunal, macrofaunal, and megafauna...

Abstract Goose and swan populations have increased concurrently with environmental degradation of wetlands, such as eutrophication, vegetation losses, decrease in biodiversity. An important question is whether geese swans contribute to changes or if they instead benefit from them. We collected data 37 wetlands southern Sweden April − July 2021 study relationships between geese, other waterbird ...

Trawling remains a controversial method of fishing due to the perceived lack of selectivity of the trawl net, which can result in the capture of a huge quantity and diversity of non-target species, including endangered species, and have a significant effect on the marine ecosystem (KUMAR & DEEPTHI, 2006). Trawl fishing has both direct and indirect impacts on the marine ecosystem as well as on b...

Lake Sonachi, Kenya, is a small alkaline-saline crater lake that over the past 175 years has experienced considerable fluctuations in lake depth (Zmax 5 3–18 m) and an alternation of meromictic and holomictic episodes lasting from a few years to several decades. Paleolimnological methods were used to reconstruct the long-term dynamics of algal and invertebrate communities in Lake Sonachi in rel...

This study is focused on benthic invertebrate communities in the Djerekarska River Serbia, sampled from June to December 2016. We examined how different microhabitats with various substrates influenced structure and function of community. Taxonomic analysis revealed 55 species 43 genera 35 families, most diverse groups being Trichoptera, Ephemeroptera, Plecoptera. ANOVA showed that substrate ty...

In the midwestern United States, maize detritus enters streams draining agricultural land. Genetically modified Bt maize is commonly planted along streams and can possibly affect benthic macroinvertebrates, specifically members of the order Trichoptera, which are closely related to target species of some Bt toxins and are important detritivores in streams. The significance of inputs of Bt maize...
