We investigated the relationship between river hydrology and least tern (Sterna antillarum athalassos) reproductive success on the Lower Mississippi River between Cairo, Illinois and Caruthersville, Missouri from 1986 through 1992. We also investigated least tern foraging behavi…

In this study, I investigated female social behavior and short-term reproductive success in hybrid baboons (Papio hamadryas anubis x P. h. hamadryas) living in Ethiopia's Awash National Park. The extremely divergent social behaviors of the hamadryas, a harem based, multi-leveled…

Mixed species colonies are common among seabirds. In Louisiana black skimmers (Rhynchops niger) usually nest with gull-billed terns (Sterna nilotica). My objective was to determine if mixed species coloniality was a function of similar nest site requirements, or if members of a …

Selection operates when the variability among individuals in heritable traits translates to differences in the number of offspring that survive to breed, which is a close estimate of fitness. Consequently, the outcome of sexual-selection should be higher reproductive success for…

In Ethiopia's Awash National Park (ANP) there is a well-documented zone of hybridization between anubis and hamadryas baboons. Frequent immigration of hamadryas males into and long-term residence within anubis/anubis-hybrid troops are considered to be among the most important fa…
