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

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.

The influence of timeshift on ciradian rhythm of sensitivity to X-irradiation in mice [PDF]
, 1984 For two groups of male C3H mice an eastbound transmeridional flight was simulated by inducing a time shift of the L:D schedule of 8 hr. The assumed flight brought about a maxima) reduction of the daily light and dark span, respectively.

North American Animated Flight Atlas
Journal of Maps, 2007 Abstract There are many different landscapes. The landscape mapped here forms in the sky as thousands of aircraft are carefully choreographed by ground control to ferry passengers from one place to another. It is this landscape of constantly moving air traffic that is the subject of a new atlas.

AntioxidantsAging is associated with detrimental bone loss, often leading to fragility fractures, which may be driven by oxidative stress. In this study, the outcomes of comparing the differences among young, adult and aged C57BL/6J mice found that the trabecular ...

Limitations on Animal Flight Performance [PDF]
Journal of Experimental Biology, 1991 ABSTRACT Flight performance seems to change systematically with body size: small animals can hover and fly over a wide range of speeds, but large birds taxi for takeoff and then fly over a narrow speed range. The traditional explanation for this is that the mass-specific power required for flight varies with speed according to a U-shaped

White-tailed deer response to vehicle approach: evidence of unclear and present danger. [PDF]
PLoS ONE, 2014 The fundamental causes of animal-vehicle collisions are unclear, particularly at the level of animal detection of approaching vehicles and decision-making. Deer-vehicle collisions (DVCs) are especially costly in terms of animal mortality, property damage,

Animal Locomotion: Near-Ground Low-Cost Flights [PDF]
Current Biology, 2018 Flying animals expend considerable energy. A new study reveals that bats reduce their flight power requirements by nearly a third when flying in 'ground effect' close to the surface.
