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 ...

ICHTIOPHAGOUS BIRDS AND POUND PROTECTION [PDF]
Croatian Journal of Fisheries, 1997 Large concentrations of fish in fishponds have always attracted ichtyophagic birds exclusively for easy and plentiful catch. In the course of the fish production process, some bird species, depending on how numerous they are, cause considerable economic ...

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.

Influence of Local Wind Conditions on the Flight Speed of the Great Cormorant Phalacrocorax carbo
International Journal of Zoology, 2012 In seabirds, the relationship between flight speed and wind direction/speed is thought to be particularly important for studying energy-saving strategy and foraging habitat selection.

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 ...

African Journal of Ecology, Volume 63, Issue 8, December 2025.ABSTRACT The Tanji wetland complex, situated on the Atlantic coast of The Gambia, is a coastal mosaic of mangroves, riparian forest, lagoons, and offshore islands of high ornithological significance. Despite its protected status, the reserve faces mounting pressures from human activities and environmental change, yet comprehensive ecological data ...
