Post‐hatching development of the remote‐tactile bill‐tip organ in precocial shorebirds (Scolopacidae)

Journal of Anatomy, EarlyView.
Juvenile scolopacid shorebirds possess well‐developed osteological correlates of tactile bill‐tip organs, indicating sensory systems for remote‐touch foraging are present from early life. Ontogenetic changes in bill‐tip morphology suggest ecological specialisation and interspecific variation develop later, after fledging in these highly precocial ...

Sexually dichromatic hybrids between two monochromatic duck species, the Chiloé wigeon and the Philippine duck

Ecology and Evolution, 2021
Captive bird hybrids can provide important data on certain traits, such as hybrid viability and fertility. In this paper, we describe four hybrids between the Chiloé wigeon (Anas sibilatrix) and the Philippine duck (Anas luzonica).

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

Restoration 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.

Structure of the Wetland‐Dependent Bird Assemblages in the Pequenos Lençóis Maranhenses, in Maranhão, Brazil

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 4, April 2026.
ABSTRACT Wetland‐dependent birds play crucial ecological roles and are highly influenced by local environmental factors such as depth, salinity and microhabitat availability. Although the importance of these environments for biodiversity is already recognized, studies on the spatiotemporal dynamics of these assemblages in Maranhão remain scarce.

Dissemination and genetic diversity of chlamydial agents in Polish wildfowl: Isolation and molecular characterisation of avian Chlamydia abortus strains.

PLoS ONE, 2017
Wild birds are considered as a reservoir for avian chlamydiosis posing a potential infectious threat to domestic poultry and humans. Analysis of 894 cloacal or fecal swabs from free-living birds in Poland revealed an overall Chlamydiaceae prevalence of ...

Evolutionary Genetics of the Anatidae

Japanese Journal of Ornithology, 1983
Thirty-one species and subspecies consisting of 169 individuals of the Anatidae were tested with 10 enzyme loci by means of electrophoresis. (1) Intra-specific genetic variation was found only in 6 species. The overall mean heterozygosity value was very low (H=0.003).(2) The mean genetic distance (D) was 0.285 among 13 genera, and 0.016 among 31 ...

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

Ecology 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 ...

Experimental Evidence Shows the Importance of Behavioural Plasticity and Body Size under Competition in Waterfowl. [PDF]

PLoS ONE, 2016
When differently sized species feed on the same resources, interference competition may occur, which may negatively affect their food intake rate. It is expected that competition between species also alters behaviour and feeding patch selection.

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

Ecology 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.

Antidiabetic Potential of Ligands from NEIST_PMIB_06, Bacterium Associated With Hawaijar (Fermented Soy Food): Insight from in Vitro and in Silico Studies

ChemFoodChem, Volume 2, Issue 1, March 2026.
ABSTRACT In this study, a bacterium (NEIST_PMIB_06) was isolated from Hawaijar, a fermented soy food from Manipur, Northeast India. The bacterium was inoculated and incubated to isolate bioactive compounds. Liquid‐liquid extraction was performed to obtain extracts (cell‐free and cell‐based), and their efficacy was evaluated.
