Relationship between carina size and sternum morphology in birds reflects physical constraints of body size and flight style

Journal of Anatomy, EarlyView.
Sternum morphology varies among birds and is a function of body mass and order. The area of the sternum is inversely related to the area of the keel suggesting that the increase in bone mass associated with a large keel has been mitigated by a reduction in bone mass of the sternum.

Prevalence and genetic diversity of avian haemosporidian parasites in wild bird species of the order Columbiformes

, 2021
Diseases can play a role in species decline. Among them, haemosporidian parasites, vector-transmitted protozoan parasites, are known to constitute a risk for different avian species.

Rapid responses of marsh birds to large‐scale tidal wetland restoration in California's Sacramento–San Joaquin Delta

Restoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is widely used to recover ecosystem function in modified estuaries, yet uncertainty remains about how quickly wildlife communities respond. Early trajectories are central to evaluating restoration success, guiding adaptive management, and building ecosystem resilience in engineered landscapes. Marsh birds

A Multispecies Systematic and Critical Review of Intranasal Administration in Veterinary Anaesthesia and Emergency Care: Promising Evidence and Overlooked Challenges

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This review evaluates the clinical potential and limitations of intranasal (IN) drug administration in veterinary anaesthesia and emergency care. IN delivery can provide clinically relevant sedation, analgesia and drug reversal, but its success is not universally reliable and is strongly influenced by species‐specific anatomy, formulation ...

Spatial distribution of acoustic traits in bird assemblages along regional bioclimatic gradients

Ecography, Volume 2026, Issue 6, June 2026.
Environmental variation shapes acoustic interactions among birds, creating spatial structures in the sonic signature of local species assemblages. Exploring these patterns at regional scales can reveal processes that segregate acoustic strategies along environmental gradients.

A phylogenetic interpretation of chromosomal and electrophoretic data in columbiformes.

CYTOLOGIA, 1979
The present paper describes the karyotype and plasma esterase isozymes in 10 species and one hybrid of Columbiformes.The genus Columba showed the greatest enzymatic polymorphism but was uniform as to the diploid chromosome number. Esterase data showed a high affinity among Leptotila, Geotrygon and Columba.

Tick‐Tac‐Foe: When Ticks, Trade, and Zoonotic Pathogens Align in African Wet Meat Markets

Public Health Challenges, Volume 5, Issue 2, June 2026.
ABSTRACT Zoonotic diseases account for over ∼60% of infectious diseases and present a significantly growing fatality threat in Africa. Live and wet markets (LWMs) in Africa function as key economic venues that support human livelihoods through social interaction and trade in food stuff, including meat and other animal‐based products.
