We tested the responsiveness of plasma androgen in free-living male arctic ground squirrels (Spermophilus parryii) to challenges from conspecific males by staging aggressive encounters between males and then comparing androgen concentrations in manipulated and unmanipulated animals. The effect of staged encounters on androgen depended on time of year. In spring, androgen levels significantly increased after staged encounters, except during the peak of mating activity when levels were maximal in… Expand

Topics from this paper

The influence of androgens on hibernation phenology of free-living male arctic ground squirrels
TLDR
It is concluded that while androgens play a significant role in spring hibernation phenology of males, their role in fall hibernation onset is unclear. Expand
Dissociation of testosterone and aggressive behavior during the breeding season in male chestnut-collared longspurs, Calcarius ornatus.
TLDR
It is suggested that high plasma testosterone may be more important in eliciting and maintaining sexual behavior than aggressive behavior in this species, and that high testosterone and male-male aggression may not be fully coupled inThis species. Expand
Social cues and hormone levels in male Octodon degus (Rodentia): a field test of the Challenge Hypothesis
TLDR
Testosterone levels were similar among pre-breeding and breeding periods, but in field animals the concentration was approximately 30% higher than in laboratory degus, suggesting that social interactions in O. degus activate a rise in testosterone, supporting the Challenge Hypothesis, and could be considered as partial support of the Social Stress Hypot hypothesis. Expand
Sexually mature and immature yearling male European ground squirrels: A comparison of behavioral and physiological parameters
TLDR
The results indicate that early puberty in European ground squirrels involves lower growth rates, high intrasexual aggression, lower prehibernatory body mass, and probably worse immunological condition during mating. Expand
Faecal androgen concentrations in adult male spotted hyaenas, Crocuta crocuta, reflect interactions with socially dominant females
Androgens influence many physiological processes in male vertebrates and have been linked to variation in aggression and reproductive behaviour in many species. This study examined relationshipsExpand
Male competition and its hormonal correlates in Assamese macaques (Macaca assamensis)
TLDR
Mechanisms of male reproductive competition and its hormonal basis in a cercopithecine species with reduced contest potential owing to female reproductive synchrony and concealed ovulation are investigated. Expand
Changing seasonality and phenological responses of free-living male arctic ground squirrels: the importance of sex
TLDR
The long-term phenology of hibernating male arctic ground squirrels living at two nearby sites in northern Alaska is investigated and it is suggested that the end of heterothermy in males is influenced by soil temperature and an endogenous circannual clock, but timing of male emergence from hibernation is affected by the timing of female emergence. Expand
Plasma steroid hormones in two Arctic-breeding shorebirds: monogamy versus polygyny.
TLDR
The results are consistent with the challenge hypothesis in that androgen concentrations were higher throughout the breeding season in the polygynous pectoral sandpipers compared to the monogamous species, and supports previous studies suggesting that the short breedingseason in the high Arctic and the importance of male care to nest success may be factors leading to behavioral T insensitivity. Expand
Testosterone predicts future dominance rank and mating activity among male chacma baboons
TLDR
The results support the challenge hypothesis with males exhibiting elevated testosterone in association with the acquisition of high rank (ensuring access to mates), rather than with mating itself, and testosterone levels predicted future, rather than current, mating activity. Expand
Seasonal programming, not competition or testosterone, drives stress-axis changes in a partially-semelparous mammal
TLDR
No evidence is found that testosterone plays a role in maintaining elevated free cortisol in arctic ground squirrel males, which suggests that high free cortisol and its effects on breeding males are not a consequence of contest competition during the breeding season, but rather a generalized seasonal change.

Seasonal changes in glucocorticoid and testosterone concentrations in free-living arctic ground squirrels from the boreal forest of the Yukon
TLDR
The primary glucocorticoid was found to be cortisol, with corticosterone below measurable concentrations in most individuals, and values were lowest in all male classes (juveniles, nonreproductive adults, and reproductive adults), being less than half those in all female classes. Expand
Differences in Weight Changes and the Annual Cycle of Male and Female Arctic Ground Squirrels
TLDR
These data are interpreted in terms of the mating period which for males lasts for approximately three weeks, whereas for females it lasts for less than a day, and male/female differences, weights, annual cycle. Expand
Seasonal fluctuations in hormones and behavior of free-living male California ground squirrels (Spermophilus beecheyi)
TLDR
It is suggested that T serves an important priming function for various seasonally fluctuating behaviors, but also that mating experience might influence the efficiency of copulatory behavior in this species. Expand
Seasonal variation in circulating testosterone and oestrogens of wild-caught California ground squirrels (Spermophilus beecheyi).
TLDR
Blood samples were obtained each month for 18 months in 1984-85 from wild-caught California ground squirrels and neither juvenile males nor females differed significantly from same-sex adults with respect to plasma concentrations of oestrogen or testosterone. Expand
Annual Cycle of Body Composition and Hibernation in Free-Living Arctic Ground Squirrels
TLDR
Timing of immergence into and emergence from hibernation for arctic ground squirrels did not differ significantly from sciurid populations in temperate latitudes and fatter females emerged significantly earlier than leaner females. Expand

TLDR
Male ground squirrels showed clear circannual cycles in body mass, testis size, and levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), and dihydrotestosterone (DHT), and during summer and fall, FSH, LH and androgen levels were low, testes were undeveloped, and body mass was increasing.

  • 1982
TLDR
The hypothesis that plasma levels of testosterone, 5α-dihydrotestosterone, and luteinizing hormone decrease precipitously at onset of incubation is supported and hormone-behavior interactions are important even in free-living animals exposed to the entire spectrum of environmental information is suggested. Expand
Vernal Changes in the Behavioral and Endocrine Responses to GnRH Application in Male European Ground Squirrels
TLDR
An exogenous pulse of GnRH can apparently release behavior in male European ground squirrels, which is normally context dependent with the emergence of females, according to the phases of the active season. Expand
Plasma androgen and gonadotropin levels during hibernation and testicular maturation in golden-mantled ground squirrels.
TLDR
Elevated levels of T during arousals and variable levels of FSH in the last days of torpor suggest that activation or increased sensitivity of the hypothalamic-pituitary-gonadal axis is important in the termination of heterothermy in ground squirrels. Expand
Seasonal changes in plasma glucocorticosteroids of free-living female yellow-pine chipmunks: effects of reproduction and capture and handling.
TLDR
Overall, the observations suggest an important role of adrenocortical activity in the energy balance of these free-living rodents in two different contexts: (1) the seasonal regulation of physiological state, including body mass, energy reserves, and reproductive function, and (2) an acute response to stimulatory events, encompassing physiological stress.
