Space Use And Mating Activities In The Speckled Rattlesnake, Xavier Glaudas Apr 2010

Space Use And Mating Activities In The Speckled Rattlesnake, Xavier Glaudas

UNLV Theses, Dissertations, Professional Papers, and Capstones

Our understanding of space use variation in response to the temporally varying importance of specific resources is poorly understood in reptiles, because spatial studies are rarely placed into an explicit ecological and behavioral context. I examined how space use differed between the mating and post-mating seasons, and how this variation related to three important resources, mating partners, food, and refuge, in an adult population of the speckled rattlesnake Crotalus mitchellii in the Mojave Desert of southwestern North America. During the mating season (late April to early June), Crotalus mitchellii increased distance traveled per unit time, because wide-ranging behavior likely enhances …


Mechanisms Of Habitat Selection Of Reintroduced Whooping Cranes On Their Breeding Range, Kelly J. Maguire, Stanley A. Temple Jan 2010

Mechanisms Of Habitat Selection Of Reintroduced Whooping Cranes On Their Breeding Range, Kelly J. Maguire, Stanley A. Temple

Proceedings of the North American Crane Workshop

We examined several mechanisms that influenced the habitat selection of reintroduced whooping cranes (Grus americana) on their breeding range in the midwestern United States. Visual observations on 56 whooping cranes from 2001 to 2006 provided accurate locations, habitat descriptions, and bird associations. Location information on each bird was mapped to create home range and to describe the habitat. We found evidence that habitat selection in these cranes resulted from multiple mechanisms, including habitat imprinting, philopatry, site tenacity, intra-specific interactions, and environmental stochasticity. The initial home ranges of all cranes contained habitat similar to that in which they were …


Habitat Selection Of Eastern Migratory Whooping Cranes On Their Wintering Grounds, Lara E. A. Fondow, Stanley A. Temple Jan 2010

Habitat Selection Of Eastern Migratory Whooping Cranes On Their Wintering Grounds, Lara E. A. Fondow, Stanley A. Temple

Proceedings of the North American Crane Workshop

As a monitoring technician for the Whooping Crane Eastern Partnership, I (LEAF) noted that birds in years following release selected wintering habitats that differed greatly from those into which they were initially released. An analysis of the habitat preferences of these birds was needed in order to determine any possible implications to the reintroduction efforts. During the winters of 2004-2005 and 2005-2006, I recorded the locations, habitat use, social associations, and behaviors of all migratory whooping cranes (Grus americana) at known locations in Florida. I used compositional analysis to determine whether habitat use was random at the following …
