Differences of water chemistry, bird assemblages and nutrient loads introduced by waterbirds into morphologically similar waterbodies

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

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 ...

Linking Habitat Conditions, Human Pressures, and Waterbird Diversity in a West African Coastal Wetland

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 ...

The impact of boat activities associated with an acoustic fish telemetry study on waterbird populations in a Special Protection Area

Conservation Science and Practice, Volume 7, Issue 12, December 2025.
Abstract It is widely recognized that the research techniques used to monitor and study wildlife have the potential to disturb and alter the behavior of the study species. However, other impacts on sensitive, non‐target, species are rarely investigated.

Loggers affect the foraging behaviour and fitness of European shags

Journal of Avian Biology, Volume 2025, Issue 6, November 2025.
Biologgers enable real‐time collection of detailed behavioural and physiological data from wide‐ranging animals, including seabirds inhabiting remote regions. However, the number of studies using tracking devices has not been matched by research exploring the behavioural and fitness costs of deployment, and the effects on data reliability.
