Osteohistology of two phorusrhacids reveals uninterrupted growth strategy
The Anatomical Record, EarlyView.Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Comparison of the Survival Rates between Migratory and Resident Birds [PDF]
, 2019 Knowledge of survival rates is critical for understanding population change for any species. Migratory species may have lower survival rates than resident species due to the physiological stress of migration and movement through unfamiliar habitat.

Animal Research and One Health, EarlyView.ABSTRACT This study explored fasting‐induced physiological remodeling effects on meat quality in aged laying hens. Fasting for 15 days (F15) significantly reduced abdominal fat, intermuscular fat width, subcutaneous fat thickness, and liver index versus pre‐fasting (F0) (p < 0.05), which recovered post‐refeeding.

Effects and observation of migrating birds on a boundary-layer windprofiler in Eastern Germany
Meteorologische Zeitschrift, 1998 Boundary-layer windprofilers recently have become more and more a standard technique for measuring lower atmospheric wind profiles operationally. Although the availability of reasonable data is quite high, there are about 2 % of all profiles which show ...

Offspring Sex Ratio in Double Brooding Prothonotary Warblers [PDF]
, 2017 Prothonotary warblers are bright, golden birds who, with their loud calls, make themselves known in wetland habitats in the spring after returning from their winter homes in the Neotropics to breed. This migratory species is important to study because of

Animal Research and One Health, EarlyView.Antimicrobial resistance (AMR) is an escalating global threat driven by antimicrobial use in aquaculture and livestock. Resistant pathogens and genes can spread across humans, animals, and the environment through interconnected ecosystems. Using a One Health approach, this review emphasizes antimicrobial stewardship, regulatory strengthening, enhanced ...
