Oceanological and Hydrobiological Studies, 2023 The number and structure of waterbirds is affected by the size of the waterbody, the presence of islands and macrophytes, but also by their trophy status. The aims of the study were to compare nutrients in water, numbers of waterbird assemblages, and the

Ecology and Evolution, Volume 16, Issue 3, March 2026.We applied eDNA metabarcoding to assess vertebrate diversity in the Rance Estuary, France, across five stations spanning marine to freshwater environments, including areas upstream and downstream of a tidal power plant dam. A total of 124 vertebrate MOTUs were detected, with community composition reflecting the estuarine gradient and species turnover ...

Swimming modes affect dive durations in diving birds
Journal of Avian Biology, Volume 2026, Issue 2, March 2026.Dive duration and body mass are positively correlated across air‐breathing vertebrate species, but other factors affecting dive duration are inadequately studied. Here, we examined the effect of a previously overlooked factor, swimming mode, using phylogenetically informed statistics with data on the diving capabilities of 53 species of avian divers ...

A Neolithic rock engraving apparently showing a Great Auk being captured
Ibis, Volume 168, Issue 1, Page 377-382, January 2026.We evaluate whether a Neolithic engraved rock image at the Alta archaeological site in Finnmark, Norway – of a bird being held by a person – represents a Great Auk Pinguinus impennis. There are several thousand engraved animal figures at Alta, created between 5000 and 2000 years ago, in various hunting panoramas.

Successful stocking of wild European perch in a reestablished lake with lasting effect over 10 years
Restoration Ecology, Volume 34, Issue 1, January 2026.Biological manipulation of fish compositions to enhance top‐down control of trophic webs is a common method for improving water and ecological quality in shallow eutrophic lakes, but it often fails. As an alternative to manually thinning unfavored fish stocks, piscivorous fish species can be released to suppress the recruitment of cyprinid fish ...

Constrained variation in the internal architecture of avian wing bones
Functional Ecology, Volume 39, Issue 12, Page 3611-3627, December 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Extant birds exhibit remarkable ecological disparity accompanied by widespread skeletal convergence driven by functional adaptation. Investigations of morphofunctional associations with ecological factors have frequently focused on the external morphology of avian wing ...
