Organisation of the benthic macroinvertebrate assemblage in tropical streams of different orders in North-Eastern Brazil

Ecología Austral, 2018
We selected streams located in north-eastern Brazil with the objective of assessing the effect of streams of different orders (1st, 2nd, 3rd) on the distribution and composition of benthic macroinvertebrates in the rainy and dry seasons.

Application of a Presumptive Standards Approach to Evaluate Environmental Flows in a Highly Regulated River Basin

River Research and Applications, EarlyView.
ABSTRACT The presumptive standards approach to environmental flows offers a method to develop interim guidelines for ecological and social‐cultural flow needs. The approach is based on deriving acceptable percent‐of‐flow limits based on naturalised flows (the absence of depletion or alteration of flow), and it can be an effective precursor to a full ...

Assessment of habitat quality using macroinvertebrates and water quality parameters of a clay quarry wetland

Journal of Advanced Research in Natural and Applied Sciences, 2021
In this study, it is aimed to determine the habitat quality of the Bozalan quarry wetland by using diversity and a compositional index of benthic macroinvertebrates and some of the water quality parameters.

Effects of Sediment‐Control Operations on Fish and Macroinvertebrate Communities in Dam Reservoirs

River Research and Applications, EarlyView.
ABSTRACT Sediments are avoided in many river and dam managements because of their adverse effects on water usage and flood control. Recently, sedimentation control measures, including sluicing, have been employed to manage sediments in river channels and restore communities in dammed rivers.

Ecological scale mediates nonlinear relationships of animal nutrient excretion with dissolved organic matter

Journal of Animal Ecology, EarlyView.
We show that nutrient excretion by vertebrates and invertebrates varies nonlinearly with dissolved organic matter concentration and composition and by taxonomic rank, with stronger patterns at the individual compared to the community level. Our findings highlight the importance of examining animal‐mediated nutrient cycling across taxa and ecological ...

Impacts of land-use intensity and land-use diversity on benthic macroinvertebrates assemblages in the Yangtze River basin, China

Ecological Indicators
Global biodiversity is declining, with changes in land use identified as a primary driver-particularly shifts in land-use intensity and diversity within riparian zones.

Limited capacity for rapid acclimation to marine heatwaves in coastal invertebrates

Journal of Animal Ecology, EarlyView.
Across 10 coastal invertebrate species, we provide a rare multi‐species test of rapid acclimation to realistic marine heatwaves. Responses are consistently weak, revealing that short‐term plasticity cannot keep pace with warming and may lead to underestimated vulnerability in coastal ecosystems. Abstract Marine heatwaves are increasing in frequency and

Would Antarctic Marine Benthos Survive Alien Species Invasions? What Chemical Ecology May Tell Us

Marine Drugs, 2022
Many Antarctic marine benthic macroinvertebrates are chemically protected against predation by marine natural products of different types. Antarctic potential predators mostly include sea stars (macropredators) and amphipod crustaceans (micropredators ...

Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

Journal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.

Trophic niche overlap between native and non‐native fishes in central Anatolian lakes, Türkiye

Journal of Fish Biology, EarlyView.
Abstract The Central Anatolian region of Türkiye exhibits exceptionally high freshwater fish diversity and endemism and is increasingly exposed to the introduction of non‐native taxa. We examined the diet composition, prey selectivity and interspecific dietary overlap among eight native and five non‐native fish species across seven lakes in Central ...
