The self-reported health of U.S. flight attendants compared to the general population [PDF]
Environmental Health, 2014 Few studies have examined the broad health effects of occupational exposures in flight attendants apart from disease-specific morbidity and mortality studies. We describe the health status of flight attendants and compare it to the U.S. population.

Flight distance and population trends in European breeding birds [PDF]
Behavioral Ecology, 2008 Flight distance reflects the risk that individual animals are willing to take when approached by a potential predator, as shown by a negative relationship between susceptibility to predation and flight distance. Species with long flight distances should more often suffer from disruption of their activities by potential predators, including humans, than

Characteristics and drivers of high-altitude ladybird flight: insights from vertical-looking entomological radar. [PDF]
PLoS ONE, 2013 Understanding the characteristics and drivers of dispersal is crucial for predicting population dynamics, particularly in range-shifting species. Studying long-distance dispersal in insects is challenging, but recent advances in entomological radar offer

American Exceptionalism: Population Trends and Flight Initiation Distances in Birds from Three Continents [PDF]
PLoS ONE, 2014 All organisms may be affected by humans' increasing impact on Earth, but there are many potential drivers of population trends and the relative importance of each remains largely unknown. The causes of spatial patterns in population trends and their relationship with animal responses to human proximity are even less known.We investigated the ...

Species traits affect phenological responses to climate change in a butterfly community
Scientific Reports, 2021 Diverse taxa have undergone phenological shifts in response to anthropogenic climate change. While such shifts generally follow predicted patterns, they are not uniform, and interspecific variation may have important ecological consequences. We evaluated

The flight apparatus of migratory and sedentary individuals of a partially migratory songbird species. [PDF]
PLoS ONE, 2012 Variations in the geometry of the external flight apparatus of birds are beneficial for different behaviors. Long-distance flight is less costly with more pointed wings and shorter tails; however these traits decrease maneuverability at low speeds ...

Hearing Health Risk in a Population of Aircraft Carrier Flight Deck Personnel [PDF]
Military Medicine, 2004 This study evaluated the risk to hearing health associated with duty on the flight deck of a Nimitz class aircraft carrier. Descriptive data includes time-weighted average noise exposure and an evaluation of temporary threshold shift for a group of nonaviator flight deck personnel (FD), and a comparison of accrued permanent threshold shift among three ...
