Ecophysiological responses of the seminal vesicle of Libyan jird (Meriones libycus) to the Saharan conditions: histological, morphometric and immunohistochemical analysis.
The Libyan jird (Meriones libycus) is a nocturnal Saharan Rodent submitted to a seasonal cycle of reproduction characterized by a short active period during spring and beginning of summer, and a long phase of sexual quiescence from the end of summer until the end of winter. During this cycle, the male reproductive organs, and more particularly seminal vesicles, experience some important weight ...
متن کاملPituitary Adrenal Axis Activity in the Male Libyan Jird, Meriones libycus: Seasonal Effects and Androgen Mediated Regulation
Many wild species exhibit seasonal cycles of testicular and adrenal functions suggesting important interrelationships between the two. However, data on desert rodents are very scarce. We investigated the pituitary adrenal (PA) axis activity of the Libyan jird from the Sahara desert, during the breeding and the non-breeding seasons. We explored, during the breeding season, the effects induced by...
متن کاملRisk assessment of heavy metal contamination in soil and wild Libyan jird Meriones libycus in Riyadh, Saudi Arabia.
This study was undertaken to document the impact of heavy metal pollution on the Libyan jird, Meriones libycus and to contribute to an environmental impact statement for the rapidly growing City of Riyadh. All metal concentrations in surface soil of a polluted site (within Riyadh City) were higherthan those from a reference site (outside the city).Although Pb declined versus earlier reports on ...
متن کاملImmunoexpression of gelatinase (MMP-2 and MMP-9) in the seminal vesicles and ventral prostate of Libyan jird (Meriones libycus) during the seasonal cycle of reproduction.
An immunohistochemical study of matrix metalloproteinases (MMP-2 and MMP-9) or gelatinase (gelatinase A and gelatinase B) was performed on the seminal vesicles and ventral prostate of the Libyan jird (Meriones libycus) collected in the Beni-Abbes area during breeding period (spring and early summer), during resting phase (late summer, autumn, winter) and from castrated animals in the spring. Th...
متن کاملintegrative taxonomy of meriones persicus (rodentia, gerbillinae) in iran
five subspecies of the persian jird, meriones persicus, were reported from iran. these subspecies were described based on morphological characters and coat colors of few specimens. the question of the validity of these subspecies and their geographic distribution is raised. in this study, we combined genetic markers (cox1, cytb and irbp genes), morphometric (external and skull measurments), mor...
