Warming up and shipping out: arousal and emergence timing in hibernating little brown bats (Myotis lucifugus)
Phenology refers to the timing of events in the annual cycle of organisms. For temperate-zone mammals, hibernation is one such event, but little is known about its phenology. Hibernation consists ofExpand

Ectoparasite Community Structure of Two Bats (Myotis lucifugus and M. septentrionalis) from the Maritimes of Canada
Prevalence of bat ectoparasites on sympatric Myotis lucifugus and M. septentrionalis was quantitatively characterized in Nova Scotia and New Brunswick by making systematic collections at swarmingExpand

Host demographic predicts ectoparasite dynamics for a colonial host during pre-hibernation mating.
Parasite dynamics can be mediated by host behaviours such as sociality, and seasonal changes in aggregation may influence risk of parasite exposure. We used little brown bats (Myotis lucifugus)Expand

Thrifty Females, Frisky Males: Winter Energetics of Hibernating Bats from a Cold Climate
Mammalian hibernation consists of energy-saving torpor bouts (periods of controlled reduction in body temperature [Tb]) interspersed with brief arousals to normothermic Tb. Frequency and duration ofExpand

The energetic significance of communal roosting and insulated roost nests in a small arid-zone passerine§
Small endotherms have evolved behavioural mechanisms for reducing rest-phase energy expenditure, which reduce the likelihood of mismatches between energy supply and demand during periods of coldExpand

Staying cold through dinner: cold-climate bats rewarm with conspecifics but not sunset during hibernation
For temperate endotherms (i.e., mammals and birds) energy costs are highest during winter but food availability is lowest and many mammals depend on hibernation as a result. Hibernation is made up ofExpand

Cold and alone? Roost choice and season affect torpor patterns in lesser short-tailed bats
Seasonal changes in weather and food availability differentially impact energy budgets of small mammals such as bats. While most thermal physiological research has focused on species that experienceExpand

The avian “hibernation” enigma: thermoregulatory patterns and roost choice of the common poorwill
Compared to mammals, there are relatively few studies examining heterothermy in birds. In 13 bird families known to contain heterothermic species, the common poorwill (Phalaenoptilus nuttallii) isExpand

Winter climate affects torpor patterns and roost choice in New Zealand lesser short‐tailed bats
Variation in winter conditions differentially impacts thermoregulation of endotherms, with some species using torpor as an energy-saving strategy during periods of negative energy balance. WeExpand
