Postcopulatory sexual selection—sperm competition and cryptic female choice—has become a major area of research over the past 40 years. Within this field there are many outstanding questions at every level of analysis, from proximate to ultimate. The fitness consequences for both sexes in the period after copulation and before fertilization...
The Next Generation Science Standards (NGSS Lead States, 2013) recommend that science courses engage communities of students in scientific practices that include building accurate conceptual models of phenomena central to the understanding of scientific disciplines. We offer a set of activities, implemented successfully at both the secondary and postsecondary levels,...
The purpose of this study was three fold: 1) to determine if false consensus
effects would be found for estimates of sexual behaviors, 2) to determine the directional
accuracy of consensus estimates for subscribers and nonsubscribers and 3) to determine if

Identifying factors related to adolescent sexual activity is an important
issue for health care, education, and public policy. This research explores the
idea that sexual identity relates to adolescent sexual activity and the riskiness of
the behavior. Sexual identity is composed of many factors, including self-esteem,
sexual self-efficacy, body image,...
I studied sexual segregation in mule deer (Odocoileus
hemionus) and white-tailed deer (Q. virginianus) in
different environments and at different population
densities to test the hypothesis that sexual segregation
occurs in ungulates as the result of different
reproductive strategies; females select habitat and behave
in manners primarily designed to promote...
The role of orange coloration in the breeding behavior of
Gambelia wislizenii was examined in the Alvord Basin of southeast
Oregon. Behavioral observations of free ranging lizards supplemented
field experiments where I manipulated the sex and color of lizards
encountered by resident female G. wislizenii before and after they
acquired...
The purpose of this research was to determine the relationship
between attitudes and behaviors pertaining to male contraceptive practices;
the influences of living group affiliation in these practices;
the influence of partners in birth control method use; the quality of
communication in the sexual relationship as an influence in birth...
