We describe a novel application of network theory to fine-scale animal movement data, using African elephants, giant Galapagos tortoises and mule deer as examples.
We examined the spatial patterns of mule deer predation during periods of high and low natural gas development activity finding complex relationships between predation and both natural and anthropogenic features.
Across multiple study sites in Colorado, mule deer body fat was not well explained by spatial or temporal effects, suggesting individual characteristics, particularly the successful weaning of fawns in the previous year are the dominant forces driving variation in body fat.
Comparing mule deer reproduction (pregnancy, fetal rates and fetal survival) between areas of low and high density natural gas development, we found limited evidence of an effect of development on reproduction. In 1 of 3 years, fetal survival was lower int he more heavily developed area.
Using a novel method to assess habtiat selection across spatiotemporal scales defined by animals movements, we show that mule deer display scale-dependent responses to most habitat features but scale-invariant avoidance of natural gas development.
In this essay we describe the similarities between the development of the fields of high-throughput genetic sequencing and high-tech animal instrumentation. We discuss the exciting possibilties that exist for better understanding the eovlution and ecology of animals by combining these two fields.
Using a movement-derived home range estimator, we documented incredibly high spatial fidelity to seasonal ranges in mule deer. Natural gas development reduced this fidelity in some case.
Extraction of oil and natural gas (hydrocarbons) from shale is increasing rapidly in North America, with documented impacts to native species and ecosystems. With shale oil and gas resources on nearly every continent, this development is set to …
While visual forms of vigilance behavior and their relationship with predation risk have been broadly examined, animals also employ other vigilance modalities such as auditory vigilance by listening for the acoustic cues of predators. Similar to the …
Illegal wildlife trade has reached alarming levels globally, extirpating populations of commercially valuable species. As a driver of biodiversity loss, quantifying illegal harvest is essential for conservation and sociopolitical affairs but …
