Temporal community change in stream ecosystems varies by assemblage across US climates

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem properties are temporally dynamic. Temporal variability has been shown to decrease with increasing levels of biological organization (i.e. from population to community and ecosystem levels).

Effects of riparian vegetation on water quality and macro invertebrates in the Gilgel Gibe Tributaries, Southwest Ethiopia

Applied Water Science
Riparian vegetation is crucial for both terrestrial and aquatic ecosystems, providing numerous essential benefits. The absence of riparian vegetation along streams can lead to various pressures that negatively affect macroinvertebrates and their habitats.

Abundance and diversity of black flies (Diptera: Simuliidae) in rivers of the Andean Eastern Hills of Bogotá (Colombia), and its relationship with water stream physicochemical variables

Universitas Scientiarum, 2018
Black flies are abundant benthic organisms in well-oxygenated running water and are considered effective bioindicators of water quality. Information on the ecology of these organisms at the species level is important, since up to now information has ...

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state

Journal of Animal Ecology, EarlyView.
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

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 ...

Benthic Macroinvertebrates Composition, Diversity and Distribution of Daberam Reservoir, Katsina State, Nigeria

UMYU Journal of Microbiology Research
Macrobenthic invertebrates are significantly considered to be bioindicators by providing a key concept in understanding the dynamics in aquatic conditions rather than chemical and microbiological data, which at least give short-term fluctuations. Recent

Comparison of Heavy Metals Accumulation Rate (Cd and Pb) in invertebrate and Fish (Alburnoides eichwaldii) in Tajan River, Mazandaran Province, Iran [PDF]

بوم‌شناسی آبزیان, 2019
This study was performed to determine the trends of heavy metals transfer (cadmium and lead) from water to macroinvertebrates and the fish species, Alburnoides eichwaldii in 5 stations in the Tajan River in autumn and spring.

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

The dual crisis: Climate change simultaneously drives pollinator decline and pest outbreaks

Agricultural and Forest Entomology, EarlyView.
Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years

Conservation Biology, EarlyView.
Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...
