This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: I studied the habitat characteristics of Mexican Spotted Owls (Strix occidentalis lucida), a federally threatened species, in the Canyonlands region of southern Utah. Vegetative and geologic features were measured within 10m wide belt plots at each current or historic nest/roost site. Based on our findings, past research, and species life history characteristics, I constructed a species distribution model (SDM) predicting Mexican Spotted Owl distribution in Utah for the Colorado Plateau region. The SDM was generated using the following inputs as important habitat variables: elevation, aspect, surface ratio, curvature, slope, geology, and vegetation. Program R was used for model development and generation. The SDM was generated using an ensemble model approach by combining three modeling techniques: random forest, logistic regression, and maximum entropy. This study combines measured habitat characteristics, with sophisticated geographic information system (GIS) tools and SDMs to provide managers with an informative and useful toolkit for Mexican Spotted Owl conservation.

This book was released on 2011 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mexican spotted owl (Strix occidentalis lucida) was listed as "threatened" in 1993 by the U.S. Fish and Wildlife Service. In Utah, the spotted owl is associated with rocky canyons that attract high levels of human recreation. Recreation could potentially have negative effects on the owl. I investigated roost behavior, territorial occupancy rates, and reproduction in canyon habitats that differed in recreation level and habitat condition (e.g., xeric versus mesic environments). Surveys were conducted in four areas in Utah: Zion and Capitol Reef National Parks, Grand Staircase-Escalante National Monument, and the Cedar Mesa-Elk Ridge highland. In Chapter 2, I evaluated possible differences in behaviors by fledglings across different levels of recreation. Fledgling diurnal behaviors were dependent on recreation level (P

This book was released on 2008 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexican spotted owls (Strix occidentalis lucida) are nocturnal avian predators that are widely distributed in the southwest U.S. and northern Mexico. In 1993, the lucida subspecies was listed as threatened in response to concern over the loss of forest habitats to which the owl is widely associated. However, in the northwestern corner of their range spotted owls primarily inhabit steep-walled rocky canyons. Owl populations inhabiting this region have received less attention than populations using forests, although, canyon populations are important to the persistence of the subspecies, and are subject to different environmental pressures. I investigated the breeding ecology and home range characteristics of Mexican spotted owls within Grand Canyon which supports both forest and rocky canyon habitat. During the study from 2004 - 2006, female fecundity (mean = 0.86), calculated as the number of female fledglings per paired female, was relatively high compared to values reported previously for Mexican spotted owls. Five adult male owls were radio-tracked during the breeding season. I used minimum convex polygons and fixed kernel estimates to describe home range size (mean = 356 ha and 372 ha, respectively) and generated adaptive kernels to describe areas of concentrated use within home ranges. I used GIS to describe vegetation and geology cover types associated with owl use areas. This information was used to determine if spotted owls used landscape cover types disproportionately to their availability. At a landscape level, spotted owl telemetry locations were positively correlated with piñyon-juniper vegetation that occurred within canyons as well as with the Redwall and Muav geologic layers (p
