Weather as a proximate explanation for fission–fusion dynamics in female northern long-eared bats
Krista J. Patriquin, Marty L. Leonard, Hugh G. Broders, W. Mark Ford, Eric R. Britzke, Alexander Silvis
2016, Animal Behaviour (122) 47-57
Fission–fusion dynamics appear common among temperate bats where females form roost groups that change in size and composition, as females switch roosts almost daily. One hypothesis for frequent roost switching is that females move to find suitable thermal conditions as ambient conditions change. Tests of this hypothesis have, however, been...

These variations are well...
Evolutionary traps as keys to understanding behavioral maladaptation
Bruce A. Robertson, Anna Chalfoun
2016, Current Opinion in Behavioral Sciences (12) 12-17
Evolutionary traps are severe cases of behavioral maladaptation that occur when, due to human activity, the cues animals use to guide their behavior become uncoupled from their fitness consequences. The result is that animals can prefer the most dangerous resources or behaviors, even when better options are available. Traps are...

Henry M. Streby, Sean M. Peterson, David E. Andersen
2016, Book chapter, Golden-winged Warbler ecology, conservation, and habitat management (Studies in Avian Biology, volume 49)
Postfledging habitat use and fledgling survival remain unstudied for most songbirds, but this period is critical for understanding breeding habitat associations and full-season productivity. We used radiotelemetry to study movements, cover-type selection, and survival of fledgling Golden-winged Warblers (Vermivora chrysoptera) during the dependent postfledging period in managed forest landscapes of...
Updated atomic weights: Time to review our table
Tyler B. Coplen, Fabienne Meyers, Norman E. Holden
2016, ChemistryViews Magazine (05 April 2016)
Despite common belief, atomic weights are not necessarily constants of nature. Scientists’ ability to measure these values is regularly improving, so one would expect that the accuracy of these values should be improving with time. It is the task of the IUPAC (International Union of Pure and Applied Chemistry) Commission...

Pathogens and insect pests have become increasingly important drivers of tree mortality in forested ecosystems. Unfortunately, understanding the relative contributions of multiple mortality agents to the population decline of trees is difficult, because it requires frequent measures of tree survival, growth, and recruitment, as well as the incidence of mortality...
White-tailed deer (Odocoileus virginianus) subsidize gray wolves (Canis lupus) during a moose (Alces americanus) decline: A case of apparent competition?
Shannon Barber-Meyer, L. David Mech
2016, Canadian Field-Naturalist (130) 308-314
Moose (Alces americanus) in northeastern Minnesota have declined by 55% since 2006. Although the cause is unresolved, some studies have suggested that Gray Wolves (Canis lupus) contributed to the decline. After the Moose decline, wolves could either decline or switch prey. To determine which occurred in our study area, we...
