Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
Pedigree‐Informed Abundance Estimation for the Endangered North Atlantic Right Whale ( Eubalaena glacialis ) via Gametic Mark‐RecaptureNARA Subscribed
Pedigrees can provide important data for abundance estimation by providing a means to infer the presence of individuals that might otherwise not be detected. Such information may be particularly important for endangered species, where the addition or removal of just a few individuals can make the difference between population growth and decline. Here, we use gametic mark‐recapture methods to incorporate pedigree information in...
While photo-identification is an effective tool to monitor individuals in wild populations, it has limitations. Specifically, it cannot be applied to very young animals before their identifying features have stabilized or to dead, decomposed animals. These shortfalls leave gaps in our understanding of survival, parentage, age structure, physical development, and behavioral variability. Here we report on 13 case studies of Nort...
Collisions with buildings cause up to 1 billion bird fatalities annually in the United States and Canada. However, efforts to reduce collisions would benefit from studies conducted at large spatial scales across multiple study sites with standardized methods and consideration of species‐ and life‐history‐related variation and correlates of collisions. We addressed these research needs through coordinated collection of data on...
Thermal constraints of energy assimilation on geographical ranges among lungless salamanders of North AmericaNARA Subscribed
Aim Understanding biogeographical patterns of variation in distributional ranges of lungless salamanders in North America by examining the relationship between geography, temperature and range. We examined how these patterns fit with Rapoport's rule, that species distributional ranges increase with increasing elevation and latitude. We also examined a possible physiological mechanism behind Rapoport's rule, the climate variabi...
