Salamander Mating Behaviors and Their Consequences for Individuals and Populations
… new information that is necessary for future mating system studies in a little studied species, the marbled salamander (Ambystoma opacum). I studied female mating behavior, sexual selection, and the consequences of polyandry for individual females and salamander populations. I also compared …

Extrapair mating behaviors in the field sparrow: nocturnal singing and extraterritorial forays
While there has been much research on the mating behaviors of birds, most attention has focused on elaborate and/or conspicuous mating displays, such as diurnal songs, ornaments, or mating dances. Much less attention has been devoted to investigating the role of more subtle behaviors, particularly …

An Assessment of the Effects of Sexual Selection and the Social Environment on Mating Behaviors in Two Tiger Beetle Species (Coleoptera: cicindelidae)
… results due to sperm competition. Facultative mating behaviors are predicted to occur in these taxa when changes in the social environment alter the benefits for guarding males. I used field observations and lab experiments in 2006 and 2007 to investigate the factors influencing mating …

Specific Roles of Kal-1 in Olfaction: A Model of Kallmann Syndrome in Drosophila
… acetate, which is known to inhibit male-male mating behaviors. Interestingly, mutant males that lack kal-1 function inappropriately court other males. These results imply a possible role of kal-1 in mating behaviors in part by mediating pheromone perception.

The impact of habitat quality on female red colobus monkey (Procolobus rufomitratus) reproduction
… data on feeding ecology, activity budgets, mating behaviors, ketone levels, and reproductive hormone concentrations. This multi-faceted approach tests a model in which habitat quality impacts diet and behaviors, which ultimately effect reproductive success. By including four research groups, …

A study of hormones and reproduction in male and female turkeys under natural mating or artificial insemination conditions
This study evaluated mating behaviors of turkeys, the effects of these behaviors on reproduction, the effects of the presence or absence of the opposite sex on reproduction and changes in serum luteinizing hormone (LH) and prolactin concentrations due to natural mating or artificial insemination. …

Investigating Experience-Dependent Plasticity in the Accessory Olfactory Bulb
… MC-interneuron plasticity is unique to specific behaviors, such as mating, or whether it is a more general feature of the AOB circuit. Here, we describe a population of AOB internal granule cells (IGCs) that upregulate expression of the immediate early gene Arc following the resident-intruder …

A deeper look into the morphology and receptors found in the tick (Acari: Ixodidae) chemoperception structure, the Haller's organ
… to ixodid ticks that assists in host seeking behaviors. Presented here are the results of a detailed comparative study of the morphology and the chemoperception gene expression of the Haller’s organ. The morphometrics study focuses on the three important North American tick species: Ixodes …

Reinforcement and cascade reinforcement in the lucania system: the effects of experimental design, sex, and heterospecific pairings on mate preference
… female L. goodei. I found that measurements of mating behaviors (i.e. egg production and courting behavior) reliably detected mate preference for male and female L. goodei, while measurements of association time failed to do the same. I also found that only female L. goodei exhibited native mate …

Genetic analyses of reproductive behavior in the domestic fowl and the Japanese quail
… of divergent selection for high and low mating frequency and the random bred control population from which the selected lines originated. In the first experiment, fertility comparisons under natural and artificial mating situations were made over time among male chickens from the selected …
