Variations saisonnières comparées du poids de la surrénale chez deux espèces de rongeurs désertiques (Psammomys obesus et Gerbillus gerbillus)

Abstract: Variations saisonnieres comparees du poids de la surrenale chez deux especes de rongeurs desertiques (Psammomys obesus et Gerb lus gerb lus)par Zama AMIRAT, Farida KHAMMAR et Roger BRUDIEUX Sous le climat de Βέηί-Abbes (Algarie), la surrenale de Psammomys obesus male est toujours beaucoup plus lourde que celle de la femelle et eile subit des variations saisonnieres plus importantes. Cependant, dans les deux sexes, son plus grand developpement se situe au printemps et son poids le plus faible en ete*; mais alor… Show more

“…In addition, the interstitial space was reduced. The results of the current work mirror those obtained in sympatric species ( Psammomys obesus, Gerbillus tarabuli and Gerbilliscus leucogaster ) (Gernigon‐Spychalowicz, 1992; Hamidatou Khati & Hammouche, 2021; Khammar, 1987; Menad et al, 2017; Muteka et al, 2018). Moreover, the changes observed in Leydig cells in our study, the increase of the nucleo‐cytoplasmic ratio and the reduction of cytoplasmic volume noticed during the resting season in Psammomys obesus and Gerbillus tarabuli , evince the inhibition of the metabolic activity of Leydig cells (Gernigon‐Spychalowicz, 1992; Hamidatou Khati & Hammouche, 2021).…”

“…However, other rodents breed during different periods of the year, including species that live in the same biotope as Gerbillus gerbillus . For example, the sand rat ( Psammomys obesus ) breeds from autumn to early spring (Khammar, 1987). The small Gerboise ( Jaculus jaculus ) breeds in Fall–Winter (Ghobrial & Hodieb, 1973), the Dwarf Gerbil ( Gerbillus nanus ) in winter (LeBerre & Chevallier, 1990), the Saharian Goundi ( Ctenodactylus gundi ) in winter–spring (Gouat, 1985) and the white‐bellied Gerbil ( Gerbilliscus leucogaster ) in autumn‐winter–spring (Muteka et al, 2018).…”
