Bryoecology In The American Southwest: Patterns Of Biodiversity And Responses To Global Change, John Carroll Brinda
Bryoecology In The American Southwest: Patterns Of Biodiversity And Responses To Global Change, John Carroll Brinda
UNLV Theses, Dissertations, Professional Papers, and Capstones
This dissertation combines investigation of the large-scale responses of bryophyte species diversity and distribution with small-scale physiological adaptations to global change. These two areas of inquiry are linked because one way to predict plant species responses to global change is to examine their distribution across current ecological gradients produced by factors such as latitude and elevation. By examining these biogeographic patterns one can identify those species that have a narrow tolerance and therefore are most sensitive to change. Selected bryophytes might then be used as indicator species in long-term monitoring programs. Where historical data exist, these can be used to …
Climate And Vegetation Change In The Newberry Mountains, Southern Clark County, Nevada, Ross Joseph Guida
Climate And Vegetation Change In The Newberry Mountains, Southern Clark County, Nevada, Ross Joseph Guida
UNLV Theses, Dissertations, Professional Papers, and Capstones
Ecological studies have shown worldwide that vegetation is being affected by climate change. Species are shifting to new elevations and physiographic positions to adapt to changes in their environment. More specifically, paleoecology studies in the Mojave Desert have shown shifting vegetation patterns in response to past warming and precipitation changes. Recent studies have shown mortality among desert plants related to extended drought and warming. However, few studies have shown how the geographic distribution of Mojave Desert species has changed during this most recent period of warming. This study addresses this gap in the literature by focusing on several plant species …
An Ecological Study Of Peregrine Falcons (Falco Peregrinus) At Lake Mead National Recreation Area, 2006-2010, Joseph Graham Barnes
An Ecological Study Of Peregrine Falcons (Falco Peregrinus) At Lake Mead National Recreation Area, 2006-2010, Joseph Graham Barnes
UNLV Theses, Dissertations, Professional Papers, and Capstones
Peregrine Falcons (Falco peregrinus) represent an encouraging conservation biology success story in North America during the twentieth century. Their distribution and population size suffered major restrictions after the initiation of widespread application of the synthetic pesticide dichloro-diphenyl-trichloroethane (DDT) within the U.S. in the 1940s. The species was federally listed as endangered in the U.S. in 1969 and was then delisted in 1999 after DDT was banned in 1972. Herein, I present my ecological research of peregrines within Lake Mead National Recreation Area (LMNRA), concentrating on the years 2006-2010. This thesis is comprised of two chapters. In the first chapter, I …
Macroinvertebrate Community Analysis On Lower Hood River Before And During The Removal Of Powerdale Dam: A Baseline Study, Howard Jay Patterson
Macroinvertebrate Community Analysis On Lower Hood River Before And During The Removal Of Powerdale Dam: A Baseline Study, Howard Jay Patterson
Environmental Science and Management Professional Master's Project Reports
Powerdale Dam was an 87-year-old hydroelectric complex on lower Hood River in northern Oregon which was decommissioned in 2010. Macroinvertebrate samples were collected in 2009, before the removal process began, and in 2010, near the end of the demolition project, at one site upstream and three sites downstream of the dam. Macroinvertebrate communities were analyzed using both multi-metric (Benthic Index of Biotic Integrity [B-IBI]) and multivariate (Predictive Assessment Tool for Oregon [PREDATOR]) approaches, as well as EPT and Functional Feeding Group (FFG) analysis. All analytical approaches indicated declines in habitat quality in 2010 relative to 2009, and showed increasing impairment …
Lake Mead National Recreation Area Monitoring And Evaluation Of Sensitive Wildlife: Final Project Report, Margaret N. Rees, Jef R. Jaeger Ph.D.
Lake Mead National Recreation Area Monitoring And Evaluation Of Sensitive Wildlife: Final Project Report, Margaret N. Rees, Jef R. Jaeger Ph.D.
Wildlife Monitoring
This task agreement was originally awarded by the National Park Service (NPS), Lake Mead National Recreation Area (LMNRA) to the Public Lands Institute at the University of Nevada, Las Vegas on September 30, 2006, and was amended to run through March 31, 2011. This agreement covered several project elements focused on:
- Monitoring and conservation actions for the relict leopard frog
- Coordinating and conducting annual bald eagle counts on Lakes Mead and Mohave
- Development and assessment of a habitat map for wintering bald eagles based on observations data collected during winter counts
- Monitoring of breeding peregrine falcons and assessment of reproductive …
