The Potential Impact Of The Medieval Climatic Anomaly On Human Populations In The Western Mojave Desert, Jill Kathleen Gardner

UNLV Retrospective Theses & Dissertations

During the late 1980s and early 1990s, a model was proposed for changing settlement and subsistence patterns in the western Mojave Desert. The model posits that environmental fluctuations over the last 4,000 years were potential causal mechanisms for culture change in this region. One of these fluctuations was the environmental episode known as the Medieval Climatic Anomaly (MCA), a series of droughts that took place between about 1,200 and 650 B.P. The intent of this study was to determine whether apparent culture changes that began about 1,200 years ago in the western Mojave Desert are associated with the MCA. To …

Microbial Endemism And Biogeography, Brian P. Hedlund, James T. Staley

Life Sciences Faculty Research

The topic of microbial biogeography is almost 100 years old, however, when confronted with questions about the existence and extent of endemism in the microbial world, many microbiologists respond with opinions and theoretical arguments rather than examples of well-conducted studies. We begin this chapter with an overview of this debate as it applies to free-living prokayotes in part because there are relatively few good microbial biogeography studies. Furthermore, the arguments help to frame microbial biogeography in the larger context of biodiversity in that if endemism is common, then many more species exist.

Ecology And Growth Of Tamias Palmeri And Testing Of A Protocol To Monitor Habitat Relationships, Christopher Eric Lowrey

UNLV Retrospective Theses & Dissertations

The ecology of Tamias palmeri is investigated. Presence-absence and relative abundance of T. palmeri are related to principle component scores of habitat variables using logistic regression and multiple linear regression, respectively. Relative abundance of Tamias palmeri estimated with live capture-recapture was positively correlated with shrub cover and negatively correlated with slope. Timing of emergence from dens by juveniles was earlier and weights of juveniles were greater in ravine areas as compared to upslope areas. Track plates were not correlated with trap captures. Track plate success was not correlated with habitat variables. The results of this study were used to build …

Remote Sensing And Geographic Information Systems For Decision Analysis In Public Resource Administration: Case Study In A Southwestern Watershed, William G. Kepner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Alternative futures analysis is a scenario-based approach to regional land planning that attempts to synthesize existing scientific information in a format useful to community decision makers. Typically, this approach attempts to investigate the impacts of several alternative sets of choices preferred by representative stakeholder groups relative to selected environmental or economical endpoints. Potential impacts from each of the scenarios are compared to current conditions of the region in terms of a set of processes that are modeled within a geographic information system. Future conditions are generally examined from the perspective of a recent baseline condition (versus empirically determined using a …

Habitat Patch Dynamics Of Desert Bighorn Sheep Ovis Canadensis Nelsoni In The Eastern Mojave Desert, Darren Del Divine

UNLV Retrospective Theses & Dissertations

The individual chapters of this Dissertation were designed to examine desert bighorn habitat, and the disjunct nature of that habitat. The findings of the first chapter illustrated that although 30 m elevation data yielded a more accurate depiction of the landscape, 100 m data was still adequate for determining habitat quality. The second chapter illustrated that the traditional bighorn habitat model was inadequate when applied to four Eastern Mojave Desert mountain ranges because of its unrealistic distance to permanent water requirement. It was also determined that a single habitat definition could not be formulated that worked equally well on all …

Evapotranspiration From A Saltcedar-Dominated Desert Floodplain: A Scaling Approach, S. D. Smith, A. M. Sala, Dale A. Devitt

Life Sciences Faculty Research

The purpose of this study was to investigate evapotranspiration (ET) from a variety of scales (leaf to landscape) in saltcedar-dominated floodplain vegetation along the lower Virgin River of southern Nevada. Leaf-level gas exchange indicated that saltcedar exhibits similar stomatal conductance as the sympatric phreatophytes arrowweed, mesquite, and willow. However, sap flow in saltcedar was higher per unit sapwood area than the other species, suggesting that it maintains higher leaf area per unit sapwood area. At the stand level, saltcedar ET was found to exceed potential ET early in the summer when soils were moist and the water table was near …

Avian Habitat Use In Southern Nevada Riparian Areas With Varying Amounts Of Tamarix Ramosissima, Sandra Lou Haigh

UNLV Retrospective Theses & Dissertations

Avian species richness, species diversity, and density were measured and compared over a 21 month period on six riparian sites in Lake Mead National Recreation Area (LMNRA), southern Nevada. Sites consisted of two lake shore areas with almost pure stands of Tamarix ramosissima and four stream side areas, two with mixed Tamarix and native vegetation and two with only native vegetation. Overall mean avian species richness, diversity, and density were lowest on lake shore sites, intermediate on mixed stream sites and highest on stream sites with native vegetation. Differences in these values were significant between lake shore and stream sites …

Analyses Of The Structure And Function Of Lower Colorado River Riparian Plant Communities, David E Busch

UNLV Retrospective Theses & Dissertations

Throughout western North America, riparian ecosystem function has been transformed by anthropogenic influences on riverine environments. Modified flood frequencies, durations or intensities, depressed floodplain water tables, and increased rhizosphere salinities contribute to change in communities formerly dominated by alluvial forest taxa. In addition, the invasion of a naturalized arborescent shrub, Tamarix ramosissima, potentially alters competitive hierarchies and disturbance regimes in riparian ecosystems. To evaluate southwestern riparian community structure and function, comparison of ecophysiological characteristics of dominant woody taxa with site physical parameters was undertaken in riparian ecosystems that are relatively pristine (Bill Williams River) and highly perturbed (lower Colorado River). …

A Diurnal Zooplankton Migration Study In Lake Mead, Robert D. Staker

Publications (WR)

The diurnal vertical movement of zooplankton was first recorded in freshwater lakes by Weismann (1877) in Lake Constance (Bodensee), although Cuvier was credited with observing the migration of Daphniae in 1817 (Gushing, 1955). The migration is best observed in deep oligotrophic lakes and migrations of 50 m per day are described (Worthington, 1931). In addition, two species of chaetognaths are reported to migrate 400 m a day in marine waters off of Lisbon (Waterman and Berry, 1967) while Birge (1895) found little evidence of the phenomenon at all in Lake Mendota, Wisconsin. Most zooplankton that migrate rise at night and …
