“…In bats, daily minimum temperature during torpor negatively affected hibernation emergence, immergence and duration (n = 3, Fig. 2a, 3b and Supporting information) in both temperate (Hodgson's bat, Myotis formosus, Kim et al 2013) and tropical species (eastern long-eared bats Nyctophilus bifax, Stawski and Geiser 2012). As temperatures across the tropics are expected to continue to rise (IPCC 2014), affecting energy use and foraging requirements, we may expect widespread disruptions to torpor in tropical hibernators (Stawski and Geiser 2012).…”

Life history consequences of climate change in hibernating mammals: a review

Climatic shifts to warmer and often drier conditions are challenging terrestrial species worldwide. These shifts are occurring more rapidly at higher elevations and latitudes, likely causing disproportionate effects to mammalian hibernators there. While there is some information about how these species' ranges are responding to climatic shifts, we lack an understanding of how climate components are affecting species' life history variation, which is key to individual success and population‐level resilience. We reviewed the literature to identify the direction of life history responses to climate change in mammalian hibernators along three axes: latitudinal, elevational and temporal. We found 39 studies involving 27 species that reported climate effects on our four target life history traits – phenology, body mass/condition and growth, reproduction and survival. We found warmer temperatures are advancing hibernator phenology and increasing reproductive success. By contrast, warming and drying trends are having uncertain effects on body condition, and complex effects on survival – depending on season, age class, latitude and elevation. We found no pattern of significant climate‐trait outcomes by duration or decade of study. More research on drought conditions – particularly in relation to resource availability – would help inform hibernator susceptibility to increased drying trends expected to intensify globally. Notably, our results are highly biased towards small mammal hibernators in Northern Hemisphere alpine/mountain ecosystems, with few long‐term studies conducted on Southern Hemisphere hibernators. This review highlights that phenological shifts constitute one of the most obvious consequences of climate change, yet, the timing of life history events (e.g. timing of migration, reproduction, hibernation) remains poorly understood. Further integration of insights from physiologists, evolutionary biologists and population ecologists working on wild populations will improve our collective understanding of the effects of seasonal climatic shifts on mammalian hibernator life history traits, key drivers of their population‐level persistence.

“…Unlike lepidopteran insects that spend their whole life cycle within a cave, T. dubitata depend on the food plants Rhamnus davurica and the Crataegus pinnatifida, outside of the cave during the egg-larva-pupa stages, but they live in the cave for long-term survival once they develop into adults. The correlation between body temperature of a bat and cave temperature is analyzed by measuring the surface temperature of the rock during their hibernacula (Kim et al 2013).…”

This study was performed to clarify the ecological characteristics of a cave‐dwelling moth species, Triphosa dubitata Linnaeus (Lepidoptera: Geometridae), at Baram cave and at Ssang cave within Pyeongchang‐gun of Gangwon province in south Korea. We investigated T. dubitata population for 3 days from March 2013 to October 2013 (except September) and in January 2014. We used a section investigation method in the caves every month to determine their ecological characteristic. A nocturnal investigation using a high intensity discharge lamp adjacent to the entrance of the cave was conducted in parallel with a diurnal investigation using butterfly traps to investigate the movement of T. dubitata. In order to investigate the range of habitat temperature of moths, we used a dual laser targeting infrared thermometer to measure the cave temperatures. We caught individuals of T. dubitata L.: 8,574 individuals in Baram cave and 828 individuals in Ssang cave. As 9,095 individuals (97 %) appeared at a temperature of −3°C ~ 8°C, it was verified that the adults were living at specific temperatures. In addition, T. dubitata adults were not active outside the caves; they entered the cave as soon as they developed from pupa into adults. These results showed that T. dubitata depended on food plants outside of the cave during the egg–larva–pupa stages, and they used the cave as a habitat for long‐term survival when they develop into adults.

“…In warmer regions, Hodgson's bats (Myotis formosus) hibernated in abandoned mines in southern Korea from October to June and interestingly maintained T skin >11 • C because of the high T a (Kim et al, 2013). The rather large (∼60 g) Formosan leaf-nosed bat (Hipposideros terasensis) hibernated in abandoned tunnels in Central Taiwan from late December to early March (Liu and Karasov, 2011).…”

Seasonal Expression of Avian and Mammalian Daily Torpor and Hibernation: Not a Simple Summer-Winter Affair†

Daily torpor and hibernation (multiday torpor) are the most efficient means for energy conservation in endothermic birds and mammals and are used by many small species to deal with a number of challenges. These include seasonal adverse environmental conditions and low food/water availability, periods of high energetic demands, but also reduced foraging options because of high predation pressure. Because such challenges differ among regions, habitats and food consumed by animals, the seasonal expression of torpor also varies, but the seasonality of torpor is often not as clear-cut as is commonly assumed and differs between hibernators and daily heterotherms expressing daily torpor exclusively. Hibernation is found in mammals from all three subclasses from the arctic to the tropics, but is known for only one bird. Several hibernators can hibernate for an entire year or express torpor throughout the year (8% of species) and more hibernate from late summer to spring (14%). The most typical hibernation season is the cold season from fall to spring (48%), whereas hibernation is rarely restricted to winter (6%). In hibernators, torpor expression changes significantly with season, with strong seasonality mainly found in the sciurid and cricetid rodents, but seasonality is less pronounced in the marsupials, bats and dormice. Daily torpor is diverse in both mammals and birds, typically is not as seasonal as hibernation and torpor expression does not change significantly with season. Torpor in spring/summer has several selective advantages including: energy and water conservation, facilitation of reproduction or growth during development with limited resources, or minimisation of foraging and thus exposure to predators. When torpor is expressed in spring/summer it is usually not as deep and long as in winter, because of higher ambient temperatures, but also due to seasonal functional plasticity. Unlike many other species, subtropical nectarivorous blossom-bats and desert spiny mice use more frequent and pronounced torpor in summer than in winter, which is related to seasonal availability of nectar or water. Thus, seasonal use of torpor is complex and differs among species and habitats.
