Lesions of the vomeronasal organ disrupt mating-induced pair bonding in female prairie voles (Microtus ochrogaster).
The prairie vole (Microtus ochrogaster) is a highly social, monogamous species and displays pair bonding that can be assessed by the presence of selective affiliation with the familiar partner versus a conspecific stranger. In female prairie voles, exposure to a male or to male sensory cues is essential for estrus induction, and the subsequent mating facilitates pair bond formation. In the pres...
متن کاملPhotoperiod and temperature interact to affect the GnRH neuronal system of male prairie voles (Microtus ochrogaster).
Individuals of numerous species limit energy expenditure during winter by inhibiting reproduction and other nonessential functions. To time these adaptations appropriately with the annual cycle, animals rely on environmental cues that predict, well in advance, the onset of winter. The most commonly studied environmental factor that animals use to time reproduction is photoperiod. Rodents housed...
متن کاملFecal microbiota in the female prairie vole (Microtus ochrogaster)
We examined the fecal microbiota of female prairie voles. This species is socially and, likely, sexually monogamous, and thus serves as a valuable model in which to examine the interaction between the microbiota-gut-brain axis and social behavior. At present, little is known about the gastrointestinal microbiota of prairie voles; therefore, we performed a first characterization of the fecal mic...
متن کاملPhotoperiod affects the gonadotropin-releasing hormone neuronal system of male prairie voles (Microtus ochrogaster).
In order to maximize survival, animals inhabiting temperate and boreal latitudes exhibit numerous adaptations to changing seasons. Central among this suite of coping strategies is the cessation of breeding during the suboptimal conditions of winter. Many nontropical rodents inhibit reproduction well in advance of winter in response to short day lengths. Male prairie voles (Microtus ochrogaster)...
متن کاملFood restriction affects the gonadotropin releasing hormone neuronal system of male prairie voles (Microtus ochrogaster).
Individuals of species inhabiting temperate and boreal latitudes optimize the timing of energetically costly processes by curtailing nonessential energetically demanding processes when environmental conditions are not favourable. One proximate environmental variable used to fine-tune moment-to-moment changes in reproductive physiology and behaviour is food intake. The neuroendocrine mechanisms ...
