Vulnerability of Croatian waterbirds [PDF]

open access: yes, 2012
Ptice pripadaju među najvažnije pokazatelje ukupnoga stanja prirode zbog svoje uske vezanosti uz staništa, složenosti životnog ciklusa i potreba za različitim staništima tijekom godine.

Shorebird responses to fine‐scale water level fluctuations and macrofauna biomass in a newly constructed freshwater wetland

open access: yesRestoration Ecology, Volume 34, Issue 4, May 2026.
Abstract Introduction Restoration of marine and freshwater wetlands for shorebirds is essential for the recovery of their declining populations. An ongoing approach is to restore shorebird habitats by large‐scale engineering, expecting the return of birds once suitable abiotic conditions are (re)established.

Sedimentary Metagenomics Reveal Avian Community Transitions From the Last Glacial Maximum to the Holocene

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We used sedimentary ancient DNA shotgun metagenomics to reconstruct past bird communities in northern high‐latitude environments. By using long time series and data collected across a large environmental gradient, we contributed in a unique and explorative way to the understanding of palaeoecological dynamics between birds and their habitat on the ...

Thyroid hormones correlate with resting metabolic rate, not daily energy expenditure, in two charadriiform seabirds [PDF]

open access: yes, 2013
K. Woo, M. Le Vaillant, T. van Nus, and especially A. Wesphal, J. Schultner and I. Dorresteijn, assisted with field work, often under unpleasant conditions. K. Wauthier was instrumental in wrestling the gamma counter into submission. P.

Effects of Regional Weather and Agricultural Practices on the Nest Survival of Northern Lapwings in France

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
This study monitored nests of lapwings with cameras and weekly visits at inland sites in eastern France, and at coastal sites in northern France. About a third of nests failed; the main causes of failure were agricultural equipment (11%), abandonment (8.2%), and depredation (7.5%). Estimates of nest survival for a 27‐day incubation were 66% and 59% for

Inventario de avifauna del norte de Entre Ríos, Argentina: registros notables y perspectivas de conservación [PDF]

open access: yes, 2018
Biodiversity inventories remain fundamental tools for biodiversity conservation. Neotropical biota has poor faunal inventories. In Argentina, the avifauna of the province of Entre Ríos is still not well known.

Comparative Genomics Reveals Genetic Adaptations to Diving‐Associated Foraging in Anseriformes

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We conducted a comparative genomic analysis of 25 Anseriformes species with diverse foraging strategies to uncover the genetic basis of diving adaptation. Diving waterfowl exhibited signatures of positive selection and functional enrichment in metabolic regulation, transmembrane transport, and neural processes essential for hypoxia tolerance.

Plutarchusia paralongitarsa sp. n. : eine neue Federmilbe (Astigmata; Pterolichoidea; Syringobiidae) [PDF]

open access: yes, 2012
Es wird eine neue Federmilbe beschrieben, Plutarchusia paralongitarsa (Pterolichoidea, Syringobiidae), die aus der Federspule einer Schwungfeder von Pluvialis tulva (Pazifischer Goldregenpfeifer) stammt.

Adaptation in the Avian Middle Ear—The Columellar Annular Ligament in Aquatic and Diving Birds

open access: yesJournal of Morphology, Volume 287, Issue 4, April 2026.
The size of the columellar footplate relative to the oval window shows striking variation across species: it fits snugly within the oval window in, for example owls (left), but considerably smaller than the oval window in diving taxa such as cormorants (right).

First Record of Two Nasal Mites Genus Rhinonyssus (Mesostigmata, Rhinonyssidae) Parasitizing Birds from Estonia

open access: yesParasitologia
Rhinonyssids are obligate hematophagous mites that parasitize the nasal cavity of domestic and wilds birds worldwide. For the first time, two species of nasal mites of the genus Rhinonyssus from Estonia are described.
