The major energy stores of reptiles and amphibians are glycogen and lipids; the reduction or depletion of lipids during hibernation is accompanied by decreases in glycogen stores, and the inadequate hibernaculum
conditions may result in extra energy consumption (Derickson, 1976; Jackson and Ultsch, 2010).
We considered a cave to be a potential hibernaculum
if it appeared deep enough to be at least partially buffered from wind and fluctuating external temperatures.
He found that some of the dye he injected in a former well on private property near the concentrated animal feeding operations, or CAFOs (as the barns are called), traveled five miles downstream to a cave that's a hibernaculum
for gray bats, one of three endangered bat species in the area.
RT RT -- -- TABLE 2--Temperature, relative humidity, soil sample locations, and the number of bats counted (total bats = 46,988) and surveyed for white-nose syndrome in various sections of the Selman Cave System, the largest known Myotis velifer gypsum-cave hibernaculum
in western Oklahoma (Woodward Co.), on 28 January 2011.
(1986) Influence of hibernaculum
microenvironment on the winter life history of the garter snake (Thamnophis sirtalis).
Instead of filling in the hole, the farmer puts a fence around it, and saves the hibernaculum
, the snakes' winter home.
leibii only disperses small distances from hibernaculum
(possibly <20 km; Hitchcock, 1955; Johnson and Gates, 2008) the species may not be present in the nearest surveyed hibernacula which are 15-30 km from the areas M.
They probably can't sense temperature changes either -- scientists have taken temperature readings and found that the hibernaculum
doesn't seem to register large swings of hot and cold that would wake the ground squirrels up.
During a field experiment in a hibernaculum
, Thomas (1995) concluded that visits by bat observers caused a dramatic increase in the flight activity of bats, beginning within 30 minutes of the visit, peaking 1.0-7.5 hours later, and remaining significantly above baseline level for up to 8.5 hours.
The mine is the biggest bat hibernaculum
in the state.
A mine that for ages served as New York's largest hibernaculum
used to host more than 200,000 bats.
