Identification of the importance of habitats that are frequently used by any species is essential to a complete understanding of the species' biology and to incorporate their ecological role into conservation and management programmes. In this context, the present study investigated whether Tasmanian coastal waters have any reproductive relevance for the broadnose sevengill shark (Notorynchus c...

The assumption that natural selection is an Optlmlslllg process, means that reproductive seasonality in mammals evolved to maximise gene survival. Although the constraints usually imposed on optimality theory are applicable, it can be assumed that periodicity in reproduction represents an adaptation to fluctuation in the availability of potentially limiting resources. In areas where these fluct...

Objective(s): To benefit from reproduction and deal with challenges in the environmental conditions, animals must adapt internal physiology to maximize the reproduction rate. Maladaptive variations in the neurochemical systems and reproductive system can lead to manifestation of several significant mammalian reprocesses, including mammalian ovarian lifespan. RFamide-related peptide (RFRP, Rfrp)...

New models for menstrual cycle-related mood disorders provide unique opportunities to gain insight into the processing of emotional information and the regulation of mood state by reproductive steroids. This paper reviews the role of reproductive steroids in affect regulation and in premenstrual dysphoric disorder (PMD), parses PMD into component processes that suggest potential mediating neuro...

The ovarian histology, the structural and the ultrastructural characteristics of the folliculogenesis in Didelphis albiventris were described in detail. Recent studies suggest that methatherian mammals have unusual reproductive cycle but there are few informations regarding the marsupials reproductive life. Despite of the opossum folliculogenesis pattern resembles methatherian and eutherian pat...

OBJECTIVE To assess whether total reproductive potential (TRP), the chance of a live birth from each fresh cycle (fresh cycle plus frozen transfers), could be calculated from the national Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) database and whether information not available in SART CORS resulted in significant changes to the TRP calculation. DE...

An overview of relationships between psychophysical measures of olfactory function and reproductive neuroendocrine processes is presented. Human studies are emphasized, and the influences of gender, menstrual cycle phase, pregnancy, and injected gonadal hormones upon olfactory perception are discussed in detail. Key Words-Pregnancy, olfactory threshold, odor preferences, hormones, estrous cycle...

Timing of reproduction in a seasonal cycle is a life history trait with important fitness consequences. Capital breeders produce offspring from stored resources and, by decoupling feeding and reproduction, may bend the constraints caused by seasonality in food or predation. Income breeders, on the other hand, produce offspring from concurrent food intake, with the disadvantage of less flexibili...
