“…The disparity in the adult sex ratio may therefore be attributed to a higher death rate among males than among females. This is contrary to what has been found in more northern species of cave bats in both North America (Griffin, 1940) and Europe (Eisentraut, 1947). However, even the females have a higher death rate in Florida than they do farther north.…”

“…This has at least been shown in several species of bats (Myotis myotis : EISENTRAUT, 1947 ;Rhinolophus ferrumequinum: RANSOME, 1968). STEBBINGS (1969) reported that 90% of his findings of dead bats away from roosts were made in April and May.…”

“…Several studies of bats show that mortality rates are highest at the end of hibernation (Eisentraut, 1947;Ransome, 1968;Stebbings, 1969), when fat reserves are low and starvation may occur. Factors that contribute to an increased probability of starvation are selection of a site that is outside the thermal neutral zone (Lyman, 1970), a long winter that extends the hibernating period (Beer and Richards, 1956), and frequent disturbance of hibernating bats causing an increased metabolic rate (Hall, 1975).…”

“…These variables can be broadly grouped into microclimatic, structural and behavioral categories. Microclimatic parameters include temperature (Eisentraut, 1934;Hock, 1951;Hanus, 1959), relative humidity (Anciaux, 1948) and airflow (Kallen, 1964). Parameters of physical structure are cave wall conformation (Twente, 1955;Krzanowski, 1959;Hall, 1962) and site exposure (Krzanowski, 1959;Bezem et al, 1964;Daan and Wichers, 1968;Daan, 1973).…”

The University of Notre Dame is collaborating with JSTOR to digitize, preserve and extend access to American Midland Naturalist.ABSTRACT: Discriminant function analysis was used to quantify both microhabitat (within-cave) and macrohabitat (among-cave) locations selected by five species of cave-dwelling bats in the limestone caves and mines of Maryland, Pennsylvania and West Virginia. Microhabitat parameters reflected microclimate, physical structure and behavioral interactions at the roosting site. Macrohabitat parameters described cave macroclimate, structure, size and external habitat features. Three discriminant functions accounting for more than 95 % of the variance were derived in the microhabitat analysis. Function I was correlated with microclimate and the tendency to cluster, function II with the exposure of the site, and function III with the draftiness of the location. There was a large degree of overlap along many of the univariate parameters, particularly temperature. Multivariate classification of the five species was 63.5% correct. Parameters that were important on a macrohabitat scale differed among species. Zones of suitable microhabitat available within a cave or mine were important factors, but presence or absence of a species at a cave or mine could not be accounted for solely by differences at this level. Cave size is shown to be important to several species in this guild. Correct multivariate classifications varied by species from 82.0 to 96.0%.
