Contribution À La Connaissance Du Cycle Annuel De La Chauve-Souris Rhinolophus Ferrumequinum (Schreber, 1774)

Abstract: Chez Rhinolophus ferrumequinum, des observations ocologiques, 1'atude histophysiologique des glandes endocrines, du tractus genital, du tube digestif et de la rate de 55 specimens autopsies aux difforentes saisons, ainsi que quelques dosages biochimiques, ne font apparaitre aucune difference systomatique entre l'otat des animaux vivant dans les grottes d'hivernage, d'octobre a mars, et celui qu'ils prosentent a d'autres opoques de l'anne*e. Sauf chez les femelles durant leur so jour dans les colonies maternell… Show more

“…Saint Girons et al (1969) and Brosset and Poillet (1985) suggest that the changes in R. ferrumequinum shelters during winter do not correspond to the changes in environment, as the temperature does not fluctuate in deep parts of caves used by horseshoe bats, but it corresponds only to the phases of annual cycle, physiological status and behavior of studied bats. In general, bats use their hibernation sites with constant air temperatures during the middle of the hibernation period.…”

“…La survie dans les regions tempe*re*es des Microchiropteres, insectivores volants au metabolisme e*leve, n'est possible que grace ä de multiples adaptations et notamment la possibility d'hypothermie reversible (Saint Girons et /., 1969). Mais, de ce fait, la poriode de vie active est trop courte pour que la spermatogenese, la gestation et l'allaitement puissent se de*rouler successivement.…”

“…Pearson, Koford & Pearson, 1952;Saint-Girons, Brosset & Saint-Girons, 1969), as a mechanism to balance energy expenditure when food supply is inadequate (Kurta, 1986). In many species, males remain solitary during the summer and, without the thermal bene®ts of clustering (Herreid, 1967;Kurta, 1986), may thus experience low ambient temperatures.…”
