Impedance spectroscopy for the characterization of swine reproductive states
This study uses machine learning to examine data acquired from a frequency sweeping electrical impedance spectrometer taking readings from sows in order to potentially determine if the resultant data can be used to predict a sow's date of estrus, date of farrowing, and if the inseminated sow has …

Ovarian and uterine changes of gray squirrels as affected by season, aged, reproductive state and exogenous hormones
… squirrel was classified as being in one of four reproductive states (vaginal orifice closed, vaginal orifice open, pregnant, or lactating). Differences in ovarian and uterine characteristics due to month, age, and reproductive state were analysed by analysis of variance and a multiple range test. …

Equine Luteinizing Hormone Profile Characteristics: Effects of Sampling Interval, Method of Analysis, Reproductive State, Gonadotropin-Releasing Hormone and Foal Removal
… hormone (LH) profile characteristics vary with reproductive state. LH profiles may change rapidly, with pulses often occurring on an hourly or even more frequent basis. Only recently have these transitory changes been examined in mares. The results from the studies in this thesis identified …

Ecology of the Eastern Massasauga (Sistrurus Catenatus Catenatus) From Carlyle Lake, Clinton County, Illinois
… during midday with >12.5 hrs of light. Sex and reproductive states (gravid females, non-gravid females, and males; SRSs) frequently changed locations but did not differ in the distances moved. Gravid female movements peaked in spring and summer, non-gravid females in spring and fall, and males …

Food and water deprivation effects on reproduction of female Blattella germanica (L.)
… of food and water deprivations during the reproductive cycle were studied. The data obtained are useful both in advancing our knowledge about the basic biology of this species, in addition to determining whether sanitation should continue to be stressed in cockroach pest management …

The Relationship of Dominance, Reproductive State and Stress in a Non-Cooperative Breeder, The Domestic Horse (<em>Equus caballus</em>)
… (dominancestress hypothesis). The effect of reproductive state on dominance and stress is not addressed within either of these hypotheses. The purpose of this study was to examine stress level in relation to dominance rank and reproductive state in a non-cooperative breeder and herbivore, the …

The Evolution of Extended Sexual Receptivity in Chimpanzees: Variation, Male-Female Associations, and Hormonal Correlates
… 2, I examined female-male relationships across reproductive states to ask whether females can better gain benefits and avoid costs by affiliating promiscuously with all males, or by investing in relationships with preferred males. Finally, I analyzed metabolites of reproductive hormones using …

Stress and sociality in a patrilocal primate: Do female spider monkeys tend-and-befriend?
… detrimental effects that can reduce health and reproductive fitness. Thus, coping mechanisms are valuable in reducing chronic stress. One such mechanism, the “tend-and-befriend” strategy, refers to affiliation between females as an adaptive strategy to deal with stress. This mechanism is …
