Feather moult and bird appearance are correlated with global warming over the last 200 years
Nature Communications, 2019 Most passerine bird species replace part of their plumage within the first year of life. Here, using data from 4,012 individuals of 19 species, Kiat et al.

Flight Zone as an Alternative Temperament Assessment to Predict Animal Efficiency
Proceedings, 2020 Animal temperament evaluation can be included in the cattle selection program also because of an existing correlation with performance. However, there are different assessment methods such as flight speed (time and speed that an animal takes to leave the

EMBO reports, 2007 Since the dawn of civilization, humans have envied their feathery companions for their ability to leap from the earth, escape gravity—and all earthly problems—and ascend to the skies. Of course, humans eventually made it into the skies too, albeit after a few millennia and rather inelegantly with the help of technology.

Wolf Responses to Experimental Human Approaches Using High-Resolution Positioning Data
Frontiers in Ecology and Evolution, 2022 Humans pose a major mortality risk to wolves. Hence, similar to how prey respond to predators, wolves can be expected to show anti-predator responses to humans. When exposed to a threat, animals may show a fight, flight, freeze or hide response. The type

Mechanisms and Implications of Animal Flight Maneuverability [PDF]
Integrative and Comparative Biology, 2002 Accelerations and directional changes of flying animals derive from interactions between aerodynamic force production and the inertial resistance of the body to translation and rotation. Anatomical and allometric features of body design thus mediate the rapidity of aerial maneuvers.

Bottlenose Dolphins and Antillean Manatees Respond to Small Multi-Rotor Unmanned Aerial Systems
Frontiers in Marine Science, 2018 Unmanned aerial systems (UASs) are powerful tools for research and monitoring of wildlife. However, the effects of these systems on most marine mammals are largely unknown, preventing the establishment of guidelines that will minimize animal disturbance.

Effect of different finishing strategies and steer temperament on animal welfare and instrumental meat tenderness [PDF]
, 2021 The aim of this experiment was to evaluate the effect of different fattening systems from pasture to concentrate and temperament on animal welfare (AW) and meat quality (MQ). Eighty-four Hereford steers were randomly assigned to the following groups: T1,

Animal Aloft: The Origins of Aerial Behavior and Flight [PDF]
Integrative and Comparative Biology, 2011 Diverse taxa of animals exhibit remarkable aerial capacities, including jumping, mid-air righting, parachuting, gliding, landing, controlled maneuvers, and flapping flight. The origin of flapping wings in hexapods and in 3 separate lineages of vertebrates (pterosaurs, bats, and birds) greatly facilitated subsequent diversification of lineages, but both

The Aerodynamics of Flapping Animal Flight [PDF]
American Zoologist, 1984 Our understanding of the aerodynamics of flapping animal flight is largely based on the quasi-steady assumption: the instantaneous aerodynamic forces on a flapping wing are assumed to be identical with those which the wing would experience in steady motion at the same instantaneous speed and angle of attack.
