Abstract Animals must balance their energy budgets even when confronted with periodic food shortages and/or adverse environmental conditions. Especially, small endothermic animals require large amounts of to maintain high and stable body temperatures ( T b ) via endogenous heat production. To deal energetic challenges, many endotherms are heterothermic, abandon regulation enter a state torpor resulting in savings. Torpor is used by bat species because they small, have rates loss rely on...
Torpor, the most effective means of energy conservation available to endotherms, is still widely viewed as a specific adaptation in few high-latitude, cold-climate endotherms with no adaptive function warm regions. Nevertheless, growing number diverse terrestrial mammals and birds from low latitudes (0–30°), including species tropical subtropical regions, are heterothermic employ torpor. Use torpor especially important for bats because they small, expend large amounts when active, rely on...
Wildfires have increased in frequency and intensity worldwide with climate change as a main driving factor. While number of studies focused on population changes regard to fires, there are essentially no quantitative data behavioural physiological adjustments that vital for the persistence individuals during after fires. Here we show brown antechinus, small insectivorous marsupial mammal, (i) endured prescribed fire situ , (ii) remained their scorched home range despite unburned areas...
A major theme in evolutionary and ecological physiology of terrestrial vertebrates encompasses the factors underlying evolution endothermy birds mammals interspecific variation basal metabolic rate (BMR). Here, we applied experimental approach compared BMR lines a wild rodent, bank vole (Myodes glareolus), selected for 11 generations for: high swim-induced aerobic metabolism (A), ability to maintain body mass on low-quality herbivorous diet (H) intensity predatory behaviour towards crickets...
Global climate change is expected to have strong effects on the world's flora and fauna. As a result, there has been recent increase in number of meta-analyses mechanistic models that attempt predict potential responses mammals changing climates. Many seek explain environmental temperatures mammalian energetics survival assume constant body temperature. However, despite generally being regarded as strict homeotherms, demonstrate large degree daily variability temperature, well ability reduce...
Abstract Knowledge of species’ functional traits is essential for understanding biodiversity patterns, predicting the impacts global environmental changes, and assessing efficiency conservation measures. Bats are major components mammalian diversity occupy a variety ecological niches geographic distributions. However, an extensive compilation their attributes still missing. Here we present EuroBaTrait 1.0, most comprehensive up-to-date trait dataset covering 47 European bat species. The...
Strong seasonality at high latitudes represents a major challenge for many endotherms as they must balance survival and reproduction in an environment that varies widely food availability temperature. To avoid energetic mismatches caused by limited foraging time stochastic weather conditions, bats employ the energy-saving state of torpor during summer to save accumulated energy reserves. However, high-latitude small-bats-in-summer face particular challenge: nocturnal foragers, rely on...
SUMMARY Seasonal changes in weather and food availability differ vastly between temperate subtropical climates, yet knowledge on how free-ranging insectivorous bats cope with such is limited. We quantified ambient temperatures, torpor patterns thermal physiology of northern long-eared bats, Nyctophilus bifax, during summer (n=13) winter (n=8) by temperature telemetry. As predicted, conditions varied significantly seasons, warmer summer. All used 85% observation days comparison to 100%...
Torpor was traditionally seen as a winter survival mechanism employed by animals living in cold and highly seasonal habitats. Although we now know that torpor is also used tropical subtropical species, response to variety of triggers, still largely viewed controlled, shown Northern hemisphere species. To scrutinize this view, report data from macroanalysis which characterized the type seasonality use mammal species currently known torpor. Our findings suggest predictable, patterns reported...
Although many tropical and subtropical areas experience pronounced seasonal changes in weather food availability, few studies have examined none compared the thermal physiology energetics of a hibernating mammal that is restricted to these regions. We quantified northern long-eared bats ( Nyctophilus bifax; body mass ∼10 g) during summer, winter, spring from habitat, also winter determine how N. bifax cope with climate weather. captured wild measured metabolic rates via open-flow...
The proportion of organisms exposed to warm conditions is predicted increase during global warming. To better understand how bats might respond climate change, we aimed obtain the first data on use torpor, a crucial survival strategy small bats, affected by temperature in tropics. Over two mild winters, tropical free-ranging (Nyctophilus bifax, 10 g, n = 13) used torpor 95% study days and were torpid for 33.5±18.8% 113 measured. Torpor duration was temperature-dependent an ambient 2°C 21st...
AbstractAlthough heterothermy is employed by species at a global level within the order of Chiroptera (bats), possibility torpor being expressed in bat inhabiting warmer climate zones has been explored only past couple decades. Recent studies suggest that benefit expressing not limited to saving energy during cold exposure or food shortage but may be just as important for water heat waves. Thus, even if physiological challenges faced bats depend on habitat they live in, should found any zone...
Gould’s wattled bat (Chalinolobus gouldii) is one of only three native Australian mammals with an Australia-wide distribution. However, currently no data are available on the thermal physiology free-ranging C. gouldii. Therefore, we aimed to quantify effect roost choice daily skin temperature fluctuations during winter in gouldii living agricultural landscape a temperate region. Ambient conditions consisted long periods below 0°C and snow. Some individuals roosted high dead branches whereas...
The asteroid strike causing global wildfires and the demise of dinosaurs many other organisms at Cretaceous-Paleogene (K-Pg) boundary ~65 Million years ago opened new niches for evolution modern mammalian lineages. While it is generally accepted that small ectotherms probably survived post-impact winter lasted months because their low metabolic rate (MR) thus food requirements, unknown how endothermic ancestors were present this time managed to do so. However, highly unlikely a strictly...
