Looking for love on a chilly night: The Colorado brown tarantula mating season
… species in the United States. While a distinct mating season is observed, it has not been well studied and the environmental drivers for the mating season are unknown. By conducting daily surveys on a peripheral population within Southeast Colorado, between August and November 2022, I found that …

Factors influencing the space use of a nonhunted population of eastern wild turkeys
… United States hunted during their reproductive season, however, there are many aspects of male reproductive ecology that are not well understand. Because male wild turkeys use a polygynous-promiscuous mating system and do not participate in nesting or brood-rearing, wild turkey research has …

Seasonal Reproduction in the Male Black Bear Ursus Americanusc and Male Polar Bear Ursus Maritimus
… and polar bear (Ursus maritimus) are long day seasonal breeders. Males undergo testicular regression during the non-mating season and testicular recrudescence during the pre-mating season. The present investigation was undertaken to begin to study the role of serum FSH, LH, and particularly PRL …

Social organization during mating, but not offspring care, influences the reproductive success of male degus, Octodon degus
… of social organization during different seasons on male reproductive success in the common degu (Octodon degus), a caviomorph rodent endemic to Chile. Male social organization was variable across years and seasons. The best fit model for male reproductive success included autumn-winter …

Female Social Connectivity through the Leadership and Movement Progression of Tibetan Macaques at Mt. Huangshan, China
… by chance, which may be a consequence of the mating season. There was a significant difference in successful movement time between movements weighted by female presence and those unweighted, which may be due to the matrilineally-structured societies and strong female bonds present.

Home range and activity in a Virginia population of Sceloporus undulatus
… period. This behavior may increase a male's mating success the following spring, as most adult males that appeared on the study site during the mating season in 1982 had been home range owners in 1981.

Male Mating Success in Lemur catta
… rank of males, number of males present during mating and harassment and interruption of mating were each examined to see how they impact male mating success. This study was conducted on four groups of ring-tailed lemur (Lemur catta) at Berenty Reserve, Madagascar, with data collected over three …

Habitat selection, survival, and disease risk of semiaquatic mammals in a highly altered landscape
… Mink also had reduced survival during the mating season, males had lower weekly survival rates than females, and subadults had lower weekly survival rates than adults. My results also revealed that exposure risk of semiaquatic mammals to the parasite Toxoplasma gondii is likely facilitated …

Revealing the behavioural ecology of the elusive hairy-eared dwarf lemur (Allocebus trichotis)
… determine habitat use, social organisation and seasonal activity cycle. We conducted field work between January and December 2007 in the Analamazaotra Special Reserve, Andasibe, central eastern Madagascar. After capturing and measuring eleven individuals, we followed two males and two females …

Occupancy dynamics, personality, & behavior of Franklin's Ground Squirrel in agricultural landscapes
… P. franklinii in agricultural landscapes during mating season in the spring. By translocating radiocollared adult squirrels across fallow crop fields and tracking routes home, I tested if individuals based gap-crossing decisions on lengths of alternate movement routes or on individual energetic …

Assessing species-specific reproductive variation to inform assisted reproductive technologies for Canadian snakes
… are increasingly incorporated into conservation mating programs for species-at-risk. Species-specific insights on reproductive biology, including seasonal variation and endocrine function, improve ART outcomes. Despite representation in many zoological collections, snakes are underrepresented in …

The role of echolocation in communication in a high duty cycle echolocating bat, Rhinolophus clivosus (Chiroptera: Rhinolophidae): an experimental approach
… with high or low body condition during the mating season. Rhinolophus clivosus was able to discriminate readily between echolocation calls with discrete frequencies from different species. When frequencies overlapped, however, the ability of bats to discriminate between species was dependant …

Scale dependent processing of conspecific signals in the gray treefrog Hyla versicolor
… grey treefrog, Hyla versicolor. During the mating season, numerous males gather near water sources and form choruses, emitting a stereotyped advertisement calls, creating a challenging auditory environment. Females later approach the chorus from daytime resting sites, often up to several …

Living apart together
… I analyse behavioural and genetic aspects of the mating system to test a recent hypothesis that proposes high extra-pair paternity in dispersed primate pairs resulting from constraints on male mate guarding. The study was conducted in Kirindy Forest in Madagascar between September 1998 and April …
