Sex-specific behavioral and physiological changes during single parenting in a biparental species, Columba livia
Horm Behav. 2023 Sep 23;156:105428. doi: 10.1016/j.yhbeh.2023.105428. Online ahead of print.ABSTRACTMany species exhibit biparental care to maximize fitness. When a partner is lost, the surviving partner may alter their behavior to compensate offspring. Whether both sexes use the same physiological mechanisms to manifest their change in behavior remains elusive. We investigated behaviors and mechanisms associated with the alteration of parental care post-partner removal in a biparental avian species, the rock dove (Columba livia). We hypothesized that rock dove single parents experience sex-biased changes in neural genomic...

Prenatal allergic inflammation in rats confers sex-specific alterations to oxytocin and vasopressin innervation in social brain regions
Horm Behav. 2023 Sep 22:105427. doi: 10.1016/j.yhbeh.2023.105427. Online ahead of print.ABSTRACTPrenatal exposure to inflammation via maternal infection, allergy, or autoimmunity increases one's risk for developing neurodevelopmental and psychiatric disorders. Many of these disorders are associated with altered social behavior, yet the mechanisms underlying inflammation-induced social impairment remain unknown. We previously found that a rat model of acute allergic maternal immune activation (MIA) produced deficits like those found in MIA-linked disorders, including impairments in juvenile social play behavior. The neurope...

Weathering the storm: Decreased activity and glucocorticoid levels in response to inclement weather in breeding Columbian ground squirrels
We examined behavioral (foraging activity) and physiological (body mass and fecal cortisol metabolites) responses of Columbian ground squirrels (Urocitellus columbianus), small hibernating rodents inhabiting open meadows in Rocky Mountains, to 3 events of inclement weather (two snow storms in May 2021 and May 2022, one heavy rainfall in June 2022). We found that individuals adapted to inclement weather conditions by (1) reducing above-ground activity, including foraging, (2) decreasing the mobilization of stored resources as indicated by a decrease in the activity of the hypothalamo-pituitary-adrenal (HPA) axis and lower f...

Conditional on the social environment? Roots of repeatability in hormone concentrations of male guinea pigs
Horm Behav. 2023 Sep 13;155:105423. doi: 10.1016/j.yhbeh.2023.105423. Online ahead of print.ABSTRACTIndividual differences in behavioral and physiological traits among members of the same species are increasingly being recognized as important in animal research. On the group level, shaping of behavioral and hormonal phenotypes by environmental factors has been reported in different taxa. The extent to which the environment impacts behavior and hormones on the individual level, however, is rather unexplored. Hormonal phenotypes of guinea pigs can be shaped by the social environment on the group level: pair-housed and colony...

Hormone physiology and sleep dynamics among BaYaka foragers of the Congo Basin: Gendered associations between nighttime activity, testosterone, and cortisol
Horm Behav. 2023 Sep 6;155:105422. doi: 10.1016/j.yhbeh.2023.105422. Online ahead of print.ABSTRACTSleep quality is an important contributor to health disparities and affects the physiological function of the immune and endocrine systems, shaping how resources are allocated to life history demands. Past work in industrial and post-industrial societies has shown that lower total sleep time (TST) or more disrupted nighttime sleep are linked to flatter diurnal slopes for cortisol and lower testosterone production. There has been little focus on these physiological links in other socio-ecological settings where routine sleep c...

Social regulation of androgenic hormones and gestural display behavior in a tropical frog
Horm Behav. 2023 Sep 6;155:105425. doi: 10.1016/j.yhbeh.2023.105425. Online ahead of print.ABSTRACTMany animals use forms of gesture and dance to communicate with conspecifics in the breeding season, though the mechanisms of this behavior are rarely studied. Here, we investigate the hormone basis of such visual signal behavior in Bornean rocks frogs (Staurois parvus). Our results show that males aggregating at breeding waterfalls have higher testosterone (T) levels, and we speculate that this hormone increase is caused by social cues associated with sexual competition. To this end, we find that T levels in frogs at the wat...
