Functional traits drive the inter-annual differences in the diversity of benthic macroinvertebrate communities associated with agricultural ditches

Journal of Freshwater Ecology
Ditches are a key feature of the agricultural landscape, especially in relation to rice cultivation. Despite being affected by anthropogenic pressures in terms of flow regulation and channelisation, they can play an important role as habitats for aquatic

Can manipulative parasites modify host‐mediated trophic effects? Experimental evidence from Schistocephalus solidus and three‐spined sticklebacks

Functional Ecology, Volume 40, Issue 6, Page 1603-1618, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Parasites can alter host traits, thereby reshaping host interactions and modifying density‐ and trait‐mediated effects in trophic cascades. But despite increasing research in parasite ecology, the cascading effects of parasitism from individual hosts to population and ...

Trophic interactions among abundant members of the fish fauna in a permanently-open and a seasonally-open estuary in South-western Australia

, 2011
Three complementary, quantitative approaches, i.e. gut content analyses, stable isotope analyses (δ15N; δ13C) and fatty acid composition, were employed to investigate the extent to which the diets of four abundant species of teleost occupying different ...

Artificial light at night and invasive signal crayfish alter aquatic‐terrestrial food webs

Functional Ecology, Volume 40, Issue 6, Page 1740-1754, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Resource flows across aquatic‐terrestrial boundaries are increasingly affected by multiple stressors, such as artificial light at night (ALAN) and aquatic invasive species, which can alter the availability of resources for consumers.

eDNA signals improve local predictions of fish abundances in Mediterranean coastal ecosystems

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
This study demonstrates that integrating eDNA metabarcoding data into species distribution models can improve fish abundance predictions, especially for site‐attached and reef‐associated species. This approach provides a scalable and cost‐effective tool for monitoring, impact assessment, spatial planning and adaptive management of marine resources ...

Macroinvertebrates and water quality: a teaching guide

, 2002
Streams support a diverse community of plants and animals on or in the stream bed. These organisms comprise the benthos. Among the benthos are worms, molluscs, crustaceans, and larval insects.

Improving Living Resource Responses in Ecosystem Restoration: An Illustration Using the Chesapeake Bay

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 3, June 2026.
ABSTRACT Two key components of large‐scale ecosystem restoration planning are: (1) prioritizing individual projects based on how living resources respond, and (2) selecting and analyzing indicators of living resources to assess restoration progress and performance.

Urbanisation Restructures but Does Not Reduce Freshwater Pond Biodiversity

Diversity and Distributions, Volume 32, Issue 6, June 2026.
ABSTRACT Aim Urbanisation is a dominant driver of landscape change leading to widespread displacement, degradation and fragmentation of habitat for native species and numerous studies have documented loss of biodiversity in response. However, most studies focus on a small range of taxa (e.g., vertebrates, plants), leaving many other groups poorly ...
