We also sampled the wall or ceiling of hibernacula
under, near (10-20 cm), and far from (>2 m) roosting bats by using the same swabbing technique.
The absence of the Northern Water Snake (Nerodia sipedon) is unclear, but it might be linked to a lack of suitable hibernacula
To find out the answer, bats from Kashmer's rehabilitation center will be brought back to hibernacula
in New Jersey and Pennsylvania.
The findings might explain why little browns--long the most common bat in the eastern United States- often suffer 90 percent or higher mortality within a year or two of white-nose arriving at their hibernacula
Although variable among bat species, mortality rates at hibernacula
of 70 to 95 percent have been reported within 2 years of an initial infection.
Durham Biodiversity Partnership asked the FoCW to build the hibernacula
to improve conditions for grass snakes along the River Derwent.
During hibernation (October-March), relative humidity and temperature in the Selman Cave System are similar to that reported from other hibernacula
Abandoned large cellars are poorly represented among the hibernacula
included in the monitoring.
These results provide evidence that snakes select hibernacula
(the sites where the snakes spend the winter) or employ thermoregulatory behaviors to maintain relatively warm winter body temperatures and that different individuals experience different body temperatures during the winter.
Research planned for 2008 includes bat hibernacula
counts, completion of carbonate cave bioinventories, and initiating surveys in sandstone and conglomerate caves of eastern Ohio.
This suggests that at least some spiders must inhabit hibernacula
sufficiently insulated to protect themselves from extreme lows for periods of several days.
The Forestry Commission and Friends of Chopwell Wood have joined with the Durham Biodiversity Partnership to build two winter hibernation chambers - or hibernacula
- for the endangered reptile in 900-acre Chopwell Wood, near Gateshead.
