Attitudes of College Undergraduates Towards Coyotes (Canis latrans) in an Urban Landscape: Management and Public Outreach Implications.

Understanding and assessing the public's attitudes towards urban wildlife is an important step towards creating management plans, increasing knowledge and awareness, and fostering coexistence between people and wildlife. We conducted a survey of undergraduate college students in the Washington, D.C.

Decreased baseline fecal glucocorticoid concentrations associated with skin and oral lesions in black rhinoceros (Diceros bicornis).

Ulcerative lesions are a health concern for managed black rhinoceros (Diceros bicornis) populations. To examine possible relationships between ex situ variables and adrenal activity with the presence of lesions, facility and socioenvironmental surveys of 25:20 (male:female) black rhinos at 18 zoos were conducted, and fecal samples were collected twice weekly for 1 yr for glucocorticoid metabolite analyses. During the collection period, 5.

Social factors influence ovarian acyclicity in captive African elephants (Loxodonta africana).

Nearly one-third of reproductive age African elephants in North America that are hormonally monitored fail to exhibit estrous cycle activity, which exacerbates the nonsustainability of the captive population. Three surveys were distributed to facilities housing female African elephants to determine how social and environmental variables contribute to cyclicity problems. Forty-six facilities returned all three surveys providing information on 90% of the SSP population and 106 elephants (64 cycling, 27 noncycling and 15 undetermined).

Spontaneous use of magnitude discrimination and ordination by the orangutan (Pongo pygmaeus).

The ability to discriminate quantity is descriptive of general cognitive ability. In this study, the authors presented 2 orangutans (Pongo pygmaeus) with a quantity judgment task. Each trial consisted of 2 choices, ranging from 1 to 6 food items in each.
