Campsurus truncatus Ulmer, 1920 (Polymitarcyidae): an Ephemeroptera in eutrophic waters

Acta Limnologica Brasiliensia, 2020
: Aim The order Ephemeroptera, together with Trichoptera and Plecoptera, has been considered as sensitive in environmental quality assessment. However, the species Campsurus truncatus Ulmer 1920 (Polymitarcyidae) has been sampled in anthropically ...

Reproduction on the Rocks: Life History of a Freshwater Macrobioeroding Bivalve. [PDF]

Ecol Evol
ABSTRACT Macrobioerosion, the excavation and removal of consolidated mineral substrates by macrofauna, is well established in marine systems, where macrobioeroders drive carbonate cycling, sediment production and habitat formation. In freshwater ecosystems, however, it has been documented in only a small number of invertebrate taxa and remains a poorly

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

Environmental DNA succeeds in detecting a low‐density population of endangered harlequin frogs

Conservation Science and Practice, EarlyView.
This work evaluates the use of environmental DNA (eDNA) to detect the Critically Endangered Jambato Harlequin Frog (Atelopus ignescens)—an iconic species once thought extinct and now known only from a single locality in the Ecuadorian Andes. Our study demonstrates the effectiveness of eDNA in detecting the Jambato in a low‐density amphibian population,

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 ...

Comparing species accumulation within taxonomically well‐ and poorly resolved insect groups over 37 years

Insect Conservation and Diversity, EarlyView.
Here, we used a unique 37‐year (1969–2006) freshwater macroinvertebrate time‐series, collected over seven sites in central Germany, to study biodiversity patterns and species accumulation over time. Accumulation curves of Diptera diversity have not reached a plateau in 37 years of sampling.

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.

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.
