An experimental test of intra- and inter-specific competition between invasive western mosquitofish (Gambusia affinis) and native plains topminnow (Fundulus Sciadicus)
… of habitat patches. This was supplemented by behavioral observations of intra- and inter-specific competition. 3. Contrary to my predictions, I did not find evidence that competition was asymmetrical from the invasive mosquitofish to the native plains topminnow. Instead, more individuals …

Behavioral and Reproductive Aspects of Captive Maxwell's Duiker (<em>Cephalophus mawellii</em>) Husbandry
… individually versus housed in a grouped setting. Behavioral observations revealed no significant change in access to resources, rumination, or repetitive behaviors, once animals were housed together. Fecal samples were collected in order to determine levels of progesterone through radioimmunoassay …

The Behavioral Signature of Permags: Examining the Behavioral Characteristics of Psychometrically Identified Putative Schizotypes
… disorders are different from controls on behavioral observations. Extending recent research (Collins, 2002) and determining its replicability in individuals with perceptual aberrations and magical ideation (PerMags), the utility of behavioral sign ratings in the identification of putative …

Effects of Different Housing Configurations on Captive Chimpanzee (<i>Pan troglodytes</i>) Behavior in Holding Area During Construction
… housing configuration. I recorded 5,664 total behavioral observations consisting of 26 different behaviors in three different housing configurations. My data showed that there was a large difference in the amount of time each chimpanzee spent in each configuration and that the chimpanzees each …
