Endocrine disruptors of the stress axis in natural populations- how can we tell?
Often, as environmental endocrinologists, we observe animals in nature with the goal of describing their normal endocrinology. However, the contamination of virtually all natural habitats by chemicals of anthropogenic origins (e.g., PCBs, organochlorines, phytoestrogens, alkyphenols, heavy metals) that might alter endocrine conditions suggests we need to reevaluate many of our field studies with respect to […]
Defensive responses of Brandt’s voles (Lasiopodomys brandtii) to chronic predatory stress
Predator odors are non-intrusive natural stressors of high ethological relevance. The objective of this study was to investigate the processing of a chronic, life-threatening stimulus during repeated prolonged presentation to Brandt’s voles. One hundred and twenty voles were tested by repeated presentation of cat feces in a defensive withdrawal apparatus. Voles exposed to feces for […]
Long-term alterations in neural and endocrine processes induced by motherhood in mammals
This article is part of a Special Issue “Parental Care”. The reproductive experience of pregnancy, lactation and motherhood can significantly remodel the female’s biological state, affecting endocrine, neuroendocrine, neural, and immunological processes. The brain, pituitary gland, liver, thymus, and mammary tissue are among the structures that are modified by reproductive experience. The present review that […]
