The present study examined the effects of pair (with a male or female) or individual housing on reproductive and immune responses in male white-footed mice (Peromyscus leucopus) maintained in long or short photoperiods. Female pairing did not affect reproductive responses in short-day males. A cross-tabulation indicated that 25 out of 39 females wanted to take male one on a dinner date or to a sporting event; 20 out of 39 wanted to take male two to a dinner date or to a theme park; 14 out of 39 wanted to take male three to a movie while the rest were more scattered.

Photoperiod alters spatial learning and hippocampal activity.

Cross‐fostering between the highly aggressive, biparental California mouse (Peromyscus californicus) and the less aggressive, less parental white‐footed mouse (P. leucopus) influences female offspring attack latency in California mice, but not in white‐footed mice. Adult female California mice raised by white‐footed mice expressed longer attack latencies in a neutral‐arena test but.

Two experiments investigate the effects of adrenalectomy on the capacity of male mice of the BDF 1 genotype (C57B1/6Fa♀×DBA/2♂) to retain sexual behaviour following castration. Adrenalectomy is without effect and it is suggested that androgens can play no part in the maintenance of sexual behaviour in these by: We studied dispersion of adult male Peromyscus leucopus in relation to the stage of pregnancy of adult females in natural populations monitored with Longworth live traps.
alter the density and. 1. Introduction. The genus Peromyscus contains more than 50 species of mice and has been used as a model system for understanding social behavior.However, most research related to maternal behavior has focused on five species: Peromyscus californicus, Peromyscus eremicus, Peromyscus leucopus, Peromyscus maniculatus, and Peromyscus five species Cited by: 3.
In a study over the summers of and in Nolde Forest near Reading, PA, we examined the impacts of roads on the behavior of white-footed deermice (Peromyscus leucopus).
Abstract. Density dependence plays a key role in determining the population sizes of rodents. To explore density-dependent effects on sexual development, we documented and analyzed the development of the sex organs and hormone concentrations in both sexes, and the time to maturity in females of the reed vole in response to different population densities under laboratory : Xuan Zhang, Meiwen Zhang, Qunhua Han, Cong Guo, Xunjun Zhou, Bo Li, Yong Wang.

FASEB J. Vessey () observed that although male Peromyscus leucopus had flexible home ranges that became compressed at high population density, females maintained a small area of spatial exclusivity regardless of population density. In our study, when population density decreased from high to relatively low values (i.e., within ), home-range size.
The most detailed studies of the effects of aromatase on behavior examine sexual behavior. Studies in birds [ 5 ], rodents [ 8 ], and primates  indicate that estrogen formed within the brain can affect various aspects of male sexual behavior (although the evidence is less clear in humans [ 94 ]).
One hundred forty-three (>55 d of age) male white-footed mice (P. leucopus) from our breeding colony were used in these experiments.
Animals were housed individually in polypropylene cages ( × × 13 cm) with a constant temperature and humidity of 21 ± 5 C and 50 ± 10%, respectively, and ad libitum access to food ( rodent diet. Abstract: This review summarizes the evidence showing that the duration of the nocturnal secretory profile of pineal melatonin (MEL) is critical for eliciting seasonally appropria.
The effects of testosterone (T) on male sexual behavior are well established, but its roles in several associated social behaviors such as pair‐bonding and paternal behavior are diverse.

Recent work from laboratory and field studies, focusing on the California mouse (Peromyscus californicus), has investigated the effect of changing behavioral contexts on USVs.
The studies included research on both males and females as well. Monogamous California mice (Peromyscus californicus) are highly social and display biparental behavior whereas promiscuous male white-footed mice (P.
leucopus) are primarily solitary during the breeding season and exhibit less paternal behavior (Madison et al. Geographic differences for delay of sexual maturation in Peromyscus leucopus. Effects of photoperiod, pinealectomy, and melatonin.
Biology of Reproduction, 41, – Adrenal lesions cover a broad spectrum from benign to neoplastic entities. Due to increased use of cross-sectional imaging they are frequently detected as incidental lesions (incidentalomas).If found incidentally, please refer to the Management of Incidental Adrenal Masses: American College of Radiology White Paper Radiology plays a significant role in differentiation.
The medulla (inner part) of the adrenal gland secretes hormones such as adrenaline (or epinephrine) and noradrenaline (or norepinephrine). These hormones manage the body’s reaction to stress and affect things like: Blood pressure; Heart rate; Sweating; The cortex (outer part) of the adrenal gland secretes steroid hormones such as cortisol and aldosterone.
Cortisol specifically helps the. Sex differences are also present in social behavior responses to stress: conditions of stress, high CORT, and high CRF facilitate pair-bonding in male prairie voles, while the same conditions impair pair-bonding in females voles (DeVries et al., ).Excess amounts of cortisol can affect the normal biochemical functioning of the male reproductive system.
Sexual Desire Chronic stress, ongoing stress over an extended period of time, can affect testosterone production, resulting in a decline in sex drive or libido, and can even cause erectile dysfunction or impotence.Short days augment spatial learning in female deer mice (Peromyscus maniculatus, Galea et al., ), and have been shown to have the opposite effect in male deer mice and white footed mice (Peromyscus leucopus, Galea et al., ; Pyter et al., ; Pyter et al., ; Pyter et al., ).
