Ecological Applications, Volume 35, Issue 5, July 2025.Abstract Food webs are not static over time, but our knowledge of their dynamics is extremely scarce due to methodological challenges. In turn, this significantly limits our ability to mechanistically understand the temporal changes that trophic networks annually undergo.

Seasonal variations of diversity and abundance of the benthic Annelida in coastal sediments of the southern Caspian Sea (Mazandaran-Sari) [PDF]
بومشناسی آبزیان, 2018 In order to investigate seasonal variation of diversity and abundance of Annelida, seasonal sediment sampling was performed on 10 stations with depths of 1, 5, 10 and 20 meters in the coastal area of Sari, Iran in 2015-2016.

Ecology and Evolution, Volume 15, Issue 7, July 2025.This study examines the invasion dynamics of the predatory invertebrate flatworm Kontikia andersoni, and its impacts on the invertebrate communities of sub‐Antarctic Macquarie Island. Our findings indicate that at higher elevations where K. andersoni is present there are significant reductions in invertebrate richness.

Differential responses of coolwater fishes to a whole‐lake reduction of a warmwater thermal guild
Ecosphere, Volume 16, Issue 7, July 2025.Abstract Climate change is transforming the ecology of lakes at a rapid pace, shifting some lakes toward warmwater‐dominant habitats. As a result, warmwater fishes are increasingly becoming more prevalent in lakes where they already existed, altering the patterning and strength of species interactions. Understanding shifting species interactions (e.g.,

Influence of human pressures on large river structure and function [PDF]
, 2009 A large river study was conducted as part of the Cross Departmental Research Pool (CDRP) ecological integrity project to (i) provide an overview of the macroinvertebrate faunas of large rivers, including those in deep-water habitats, and (ii) to ...

The response of perennial and temporary headwater stream invertebrate communities to hydrological extremes [PDF]
, 2009 The headwaters of karst rivers experience considerable hydrological variability, including spates and streambed drying. Extreme summer flooding on the River Lathkill (Derbyshire, UK) provided the opportunity to examine the invertebrate community response

Acta Limnologica Brasiliensia, 2017 Numerous factors may affect the pattern of distribution of benthic fauna in a river mouth region and, among the macroinvertebrates, Chironomidae and Oligochaeta are the most abundant groups and most tolerant to environmental changes. Aim The aim of this
