Molecular-genetic characterization of Avian avulavirus 20 strains isolated from wild birds

open access: yesВопросы вирусологии, 2019
Introduction. Previously unknown paramyxovirus strains were isolated from wild birds in 2013-2014 in Kazakhstan and subsequently identified as representatives of the novel Avian avulavirus 20 species.

Ecology of Laridae under conditions of unstable hydrological regime: colony sizes and synchronization of reproduction

open access: yesBiosystems Diversity, 2021
The problem of criteria for distinguishing colonies from similar socio-demographic structures (mainly in terms of nesting density) is highly relevant and has remained in the focus of attention of ornithologists for a long time.

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds

open access: yesJournal of Anatomy, EarlyView.
The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.

Seasonal and circadian patterns of herring gull (Larus smithsoniansus) movements reveal temporal shifts in industry and coastal island interaction

open access: yesEcological Solutions and Evidence, 2023
Anthropogenic food subsidies attract opportunistic generalists like gulls in high densities, which may lead to negative impacts on human communities and local ecosystems.

Feathers and flu: identifying data gaps in avian influenza host dynamics to prioritize wildlife conservation Plumas y gripe: identificación de datos faltantes en la dinámica de hospedadores de la influenza aviar para priorizar la conservación de la vida silvestre

open access: yesWildlife Monographs, Volume 225, Issue 1, September 2026.
We describe the host response continuum for highly pathogenic avian influenza viruses (HPAIV), including the continuum of host responses to HPAIV infection and exposure based on the primary axis of host competence, ability to infect other hosts, and host vulnerability.

Complete mitochondrial genome of Chroicocephalus brunnicephalus from India: phylogeny with other Larids

open access: yesMitochondrial DNA. Part B. Resources, 2021
The complete mitogenome sequence of the brown-headed gull, Chroicocephalus brunnicephalus was determined in this study. The 16,771 bp genome consists of 13 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, and 22 transfer RNA (tRNA) genes, and

Reproducción del Gaviotín Sudamericano Sterna hirundinacea (Charadriiformes: Laridae) en el Lago Epecuén, Buenos Aires, Argentina

open access: yesActa Zoológica Lilloana, 2021
El Gaviotín Sudamericano (Sterna hirundinacea) es una especie costero-marina, migratoria y exclusiva de Sudamérica. Si bien se ha registrado en varios cuerpos de agua interiores en territorio argentino, hasta el momento todos los eventos de nidificación ...

Between‐species contagion drives HPAI transmission and mass mortality in seabirds

open access: yesJournal of Animal Ecology, Volume 95, Issue 8, Page 1488-1503, August 2026.
Modelling the unprecedented avian panzootic caused by High‐Pathogenicity Avian Influenza (HPAI) across the Northeast Atlantic gannet breeding metapopulation, we estimated 28% (95% CI: 21%–34%) HPAI‐related mortality. Large‐scale outbreak initiation was best explained by external infection sources, most likely, other seabird species.

Characterization of the mitogenomes for two sympatric breeding species in Recurvirostridae (Charadriiformes) and their phylogenetic implications

open access: yesMitochondrial DNA. Part B. Resources, 2017
Recurvirostridae is a family of Charadriiformes that displays an amazing amount of characterization at evolutionary level. The mitogenomes of Himantopus himantopus and Recurvirostra avosetta are 17,378 bp and 16,856 bp in size, respectively.
