Reproductive suppression in subordinate female highveld mole-rats (Cryptomys hottentotus pretoriae): no role for endogenous opioid peptides.

abstract：:When animals are reared for conservational releases it is paramount to avoid reducing genetic and phenotypic variation over time. This requires an understanding of how diverging behavioural and physiological traits affect performance both in captivity and after release. In Atlantic salmon, emergence time from the spaw...

We addressed this question by examining restrained eaters' brain response to food (chocolate) and non-food (geraniol, floral) odors, both when odor was attended to and when ignored.
