The drivers of benthic macroinvertebrates communities along a subtropical river system: Sediments chemistry or water quality?

open access: yesEcohydrology, Volume 17, Issue 5, July 2024.
Abstract Impacts of metal pollution, either on water or in sediments within aquatic systems have been a serious challenge globally. Little is known about the ecological impacts of metal pollution on benthic macroinvertebrates species in sub–tropical river systems.

Ausência da relação de fatores abióticos sobre riqueza e abundância de veliidae (Heteroptera) em igarapés da Amazônia Oriental [PDF]

open access: yes, 2022
As alterações antrópicas influenciam na riqueza de espécies, muitas dessas alterações ocorrem em ambientes aquáticos. Ações antrópicas, como queimadas, desmatamento, e monoculturas afetam diretamente os igarapés e suas variáveis físicoquímicas. Com isso,

Similarity of stream insect trait profiles across biogeographic regions

open access: yesDiversity and Distributions, Volume 30, Issue 4, April 2024.
Abstract Aim Habitat templet theory predicts that the functional niches of species evolved in response to selection pressures imposed by each species' spatial–temporal environment. Consequently, similar environmental conditions should lead to convergence in the biological trait composition of biogeographically independent assemblages.

Facilitation of benthic assemblages by Bluehead Chubs: Testing the stress‐gradient hypothesis in streams

open access: yesEcology of Freshwater Fish, Volume 33, Issue 2, April 2024.
Abstract Ecosystem engineers facilitate beneficiary species by ameliorating physical habitat. The stress‐gradient hypothesis (SGH) predicts the importance of facilitation in communities should increase with physical stress but has rarely been tested in freshwater.

The effects of land‐use change on semi‐aquatic bugs (Gerromorpha, Hemiptera) in rainforest streams in Sabah, Malaysia

open access: yesFreshwater Biology, Volume 69, Issue 4, Page 556-572, April 2024.
Abstract Land‐use change and agricultural expansion have caused marked biodiversity loss in Southeast Asia, but impacts on freshwater communities have been very little studied. Semi‐aquatic bugs are abundant in streams, provide prey for many other animals, and are sensitive to environmental change, making them a relevant group for studying land‐use ...
