Winter Vertebrate Browsing Of Birch: Effects On The Use Of Leaf Litter Leachates By Stream Microorganisms, Jeffrey L. Estensen

Biological Sciences

Winter browsing of birch leads to chemical changes in leaves of the following growing season, potentially generating differences in the quality of leachates derived from leaf litter and in leachate use by stream microorganisms. The effects of moose browsing were tested on leachates from leaves collected from browsed and unbrowsed trees and inoculated with microbial communities. Respiration and bacterial abundance were used to assess qualitative differences in leachates. Microbes cultured in leachates derived from leaves of browsed trees had significantly higher rates of oxygen uptake. There were no significant differences in bacterial abundance between treatments. The basis for the qualitative …

Paper Session Ii-C - Collaborative Ukrainian Experiment - Science And Technology Exchange Program For Students (Cue-Steps), Thomas W. Dreschel Ph.D., V. Chetirkin, S. Behel, V. I. Nazarenko

Space Congress® Proceedings

An educational program was initiated during the Collaborative Ukrainian Experiment (CUE) in 1997. The CUE project was a series of plant experiments performed by Ukrainian cosmonaut, Leonid Kadenyuk, on Mission STS-87. A collaborative educational program was developed which was called "CUE-Teachers and Students Investigating Plants in Space (TSIPS)" in which students from both the U.S. and Ukraine conducted ground controls for the space experiments. The educational collaboration established during this project has continued with the development of other programs. These programs included the NASA SEEDS II project, the NASA Farming in Space Project, the International Water Institute and most recently, …

The Potential For Support Of Gardner's Theory Of The Naturalist Intelligence In Selected Elementary School Library Media Centers, Traci L. Haines

Theses and Dissertations

The concept of teaching to the ability of the child is complex. Each child absorbs, analyzes and processes information differently. Howard Gardner developed a series of eight intelligences describing the variety of ways in which children learn. This study focused on the Naturalist Intelligence, an ability to recognize and discriminate different concepts in nature. A naturalist learner has strong observational skills and is good at sorting and classifying (Checkley, 1997). This evaluation compares randomly selected samples of the collections of two elementary school library media centers in order to determine whether the books in the 500s support Gardner's Theory of …

Phylogenetic Relationships, Taxonomy, And Evolution Of Host Choice In Diadasia (Hymenoptera: Apoidea), Sedonia D. Sipes

Biology

I examined the phylogenetic relationships, taxonomy, and evolution of host choice in Diadasia, a genus of New World bees. Diadasia species are particularly interesting because they are considered pollen specialists. Females of each species are believed to provision their nests with pollen from only a few closely related plant taxa. At the same time, the choice of floral hosts within the genus is diverse, and includes five distantly related plant families: Malvaceae, Onagraceae, Convolvulaceae, Asteraceae, and Cactaceae. To estimate phylogenetic relationships within this group, I sequenced ~ 2 kb of the mitochondrial genes CO I and II and tRNA …

Morphometric Evaluation Of The Whitefish Complex In Bear Lake, Utah/Idaho, Alan Ward

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Whitefish populations around the world have long been difficult to categorize taxonomically. The whitefish of Bear Lake, Utah/Idaho are no exception. There are three recognized species of Prosopium that are endemic to the lake. Two of these species, Prosopium spilonotus and Prosopium abyssicota, have previously been indistinguishable outside of spawning times. Previous studies have proposed additional taxa within P. spi/onotus to further complicate the identification among these taxa.

Morphological characteristics were quantified on wild whitefish from Bear Lake, as well as from progeny reared in the laboratory from the wild adult fish. The purported taxa were separated in the field …

Comparison Of Rodent Communities Of Native Brushland, Replanted, And Secondary Succession Sites In The Lower Rio Grande Valley Of Texas, Mitchell Allen Sternberg

Theses and Dissertations - UTB/UTPA

I compared small mammal communities between mature brushlands, replanted brushlands, and secondary succession sites from November 1998 to December 1999 to evaluate revegetation efforts in the Lower Rio Grande Valley of Texas. I determined rodent community characteristics of the three habitat types. The mature brushland and replanted habitats had similar species diversities and both were significantly higher than the secondary succession habitat. Species diversity was highest at the replanted edge grid during Winter. The current replanting method provides a more diverse rodent community than does natural succession from fallow fields. Wildlife monitoring should be extended to other taxonomic guilds so …

Introduced Wildlife Of Oregon And Washington , Gary W. Witmer, Jeffrey C. Lewis

United States Department of Agriculture Wildlife Services: Staff Publications

Each species of wildlife occurs as part of an ecosystem, interacting in many ways with other plant and animal species in that system as well as with the abiotic components such as soil, air, water, and other substrates. The array of wildlife species around the globe has been shaped by geological and climatological events as well as by eons of evolution and natural selection. Species have come and gone and those remaining have, in most cases, co-evolved or co-adapted with many other species so that relatively stable, and often complex, relationships exist. Usually, a great many niches have been carved …

Fishtail Mesa: A Vegetation Resurvey Of Relict Area In Grand Canyon National Park, Arizona, Peter G. Rowlands, Nancy J. Brian

Western North American Naturalist

Relict sites are geographically isolated areas that are undisturbed by direct and indirect human influences. These sites facilitate long-term ecological monitoring by providing a reference for gauging impacts occurring elsewhere. Knowledge gained through comparing vegetation change on matched relict and proximal disturbed areas can help partition the causes of change into natural and human-produced components. Fishtail Mesa in Grand Canyon National Park is a 439-ha relict site that is inaccessible to domestic livestock. Human visitation is infrequent and irregular, and fires have never been suppressed or managed. In 1958, U.S. Forest Service range scientists conducted a survey of Fishtail Mesa …

Establishment, Growth, And Early Survival Of Woody Riparian Apecies At A Colorado Gravel Pit, James E. Roelle, Douglas N. Gladwin, Brian S. Cade

Western North American Naturalist

Presence of a wetted edge during the period of seedfall was an effective predictor of suitable establishment (defined as germination and survival to the 1st autumn) locations for Populus deltoides subsp. monilifera, Salix amygdaloides, S. exigua, and Tamarix ramosissima seedlings during 3 successive years of a gravel pit revegetation project in Fort Collins, Colorado. At locations predicted to be suitable for establishment, position within the pit (possibly reflecting additional moisture provided by seepage) was a significant factor in determining whether establishment actually occurred. Cover of herbaceous species, which became established at the same time as, or after, woody seedlings, was …

Modeling The Influences Of Climate Change, Permafrost Dynamics, And Fire Disturbance On Carbon Dynamics Of High -Latitude Ecosystems, Qianlai Zhuang

Biological Sciences

A Soil Thermal Model (STM) with the capability to operate with a 0.5-day internal time step and to be driven with monthly input data was developed for applications with large-scale ecosystem models. The use of monthly climate inputs to drive the STM resulted in an error of less than 1�C in the upper organic soil layer and in an accurate simulation of seasonal active layer dynamics. Uncertainty analyses identified that soil temperature estimates of the upper organic layer were most sensitive to variability in parameters that described snow thermal conductivity, moss thickness, and moss thermal conductivity. The STM was coupled …

Carbon And Nitrogen Isotopes In Archeological Bison Remains As Indicators Of Paleoenvironmental Change In Southern Alberta, Jeremy J. Leyden, Gerald Oetelaar

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Between 1995 and 1997, archeological excavations in northwest Calgary, Alberta, uncovered cultural materials from several occupations dating back 8,500 years. Samples of bison bone recovered at the sites were chemically prepared and analyzed for isotopic ratios. Using the resultant carbon and nitrogen isotope ratios, we reconstructed the diet of bison from four different cultural occupations spanning the last 8,500 years. Based on current and established models of bison subsistence behavior, this dietary information was used to infer large-scale environmental changes during this time interval in our study area. The inferred changes in vegetation and climate were compared with paleoenvironmental reconstructions …

What The Past Can Provide: Contribution Of Prehistoric Bison Studies To Modern Bison Management, Kenneth Cannon

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

For over 100 years, bison in the Greater Yellowstone Area have been managed intensely. Even during the years of "natural regulation," bison herds have been heavily managed by culling. One of the fundamental goals of the plan for the Greater Yellowstone Area is to maintain the ecosystem's integrity using sound science. In order to reach this goal, it must be recognized that it is a dynamic system, continually undergoing change. However, our knowledge of such changes is extremely limited. In the case of bison, our knowledge is based on nonsystematically collected historic records and modern studies of small, isolated populations. …

Treefall Gaps And The Maintenance Of Species Diversity In A Tropical Forest, Stefan A. Schnitzer, Walter P. Carson

Biological Sciences Faculty Research and Publications

The maintenance of species diversity by treefall gaps is a long‐standing paradigm in forest ecology. Gaps are presumed to provide an environment in which tree species of differing competitive abilities partition heterogeneous resources. The empirical evidence to support this paradigm, however, remains scarce, and some recent studies even suggest that gaps do not maintain the diversity of shade‐tolerant species. Although there is evidence that gaps maintain the diversity of pioneer trees, most of this evidence comes from studies that did not make comparisons between gaps and intact forest sites (controls). Further, nearly all studies on the maintenance of diversity by …

The Effect Of Nitrogen Fertilization On Short-Term Fine Root Dynamics In A Barrier Island Dune Community, John Walter Hutton

Biological Sciences Theses & Dissertations

Fine root dynamics are an important yet poorly understood component of terrestrial ecosystems. In recent years a number of researchers have focused on fine root dynamics; their work has looked at patterns across one or multiple growing seasons on a scale of monthly measures. The purpose of this study was to add to the overall understanding by looking at fine root dynamics on a shorter temporal scale. Minirhizotron observation tubes were used to assess the effect of nitrogen fertilization on short-term fine root dynamics in a nutrient limited, barrier island dune system. Root length elongation and mortality rates followed expected …

Income Distribution And Health: A Worldwide Analysis, Ketan Amin '01

The Park Place Economist

Despite having had nearly a decade of economic growth, the United States is among many developed countries that lag behind under developed countries on various health indicators such as life expectancy. Although access to universal health care is also a major contributor to the level of health of a nation, growing evidence suggests that broader economic forces may be playing a larger role in determining a nation’s health status.

Preliminary Checklist Of The Orthopteroid Insects (Blattodea, Mantodea, Phasmatodea,Orthoptera) Of Texas, John A. Stidham, Thomas A. Stidham

Insecta Mundi

Texas has one of the most diverse orthopteroid assemblages of any state in the United States, reflecting the varied habitats found in the state. Three hundred and eighty-nine species and 78 subspecies of orthopteroid insects (Blattodea, Mantodea, Phasmatodea, and Orthoptera) have published records for the state of Texas. This is the first such comprehensive checklist for Texas and should aid future work on these groups in this area.

Feeding Ecology Of The Blackwing Searobin Prionotus Rubio (Jordan, 1886) Over The Western Continental Shelf Off Alvarado, Veracruz, Mexico, Victor H. Cruz-Escalona, L. Andres Abítia-Cárdenas, Lucia Campos-Dávila, Felipe Galvan-Magaña

Gulf of Mexico Science

Seasonal changes of food habits of the blackwing searobin Prionotus rubio were studied over the continental shelf off Alvarado, Veracruz, Mexico, from Sept. 1994 to Aug. 1995. A total of 234 stomachs (182 with identifiable food) were analyzed. Brown shrimp Farfantopenaeus aztecus, blue crab Portunus spinicarpus, and rock shrimp Sicyonia dorsalis were the main dietary items. Low values of prey diversity and dietary breadth suggest the main prey were always relatively abundant over the western continental shelf of the Gulf of Mexico. We concluded the blackwing searobin is part of a trophic guild of demersal marine fish that …

Diet Composition Of Juvenile Pigfish, Orthopristis Chrysoptera (Perciformes: Haemulidae), From The Northern Gulf Of Mexico, Jeffrey C. Howe

Gulf of Mexico Science

Diets of 954 juvenile pigfish, Orthopristis chrysoptera, collected from 14 1-m³ concrete block artificial reefs approximately 20 km south of Mobile Bay, AL, were examined. A total of 137 specimens (14.4 %) contained food items and were used to perform stomach content analysis. Index of Relative Importance was used to evaluate the contribution of major foods by combining frequency of occurrence, volume, and number. Diets were dominated by shrimps and polychaetes and, to a much lesser extent, sea anemones, fishes, crustaceans, cephalopods, and gammarids. Many stomachs contained various quantities of sand, which indicated a certain amount of bottom …

Abundance, Spatial Distribution, And Mortality Of Young-Of-The-Year Spotted Seatrout (Cynoscion Nebulosus) Along The Gulf Coast Of Florida, Gary A. Nelson, Deborah Leffler

Gulf of Mexico Science

We used fixed-station and random-station sampling data from the period 1989-97 to examine spatial and temporal patterns in the abundance and size structure of young-of-the-year (YOY) spotted seatrout, Cynoscion nebulosus, in three Florida estuaries. YOY seatrout first appeared at shallow-water (<1.5 m) seine sites in May-June in Choctawhatchee Bay (Florida Panhandle) and in April-May in Tampa Bay and Charlotte Harbor (both along the southwest Florida peninsula). Spotted seatrout were caught at deepwater (> 1.6 m) trawl stations within 1-3 mo of their initial appearance at shallow-water sites. Most spotted seatrout were caught in waters <3.7 m. Spring and summer peal's in YOY abundance, corresponding to strong influxes of newly spawned individuals, were observed only in southwest peninsula estuaries. Depending on the estuary, the occurrence of YOY spotted seatrout at shallow-water sites was associated with some combination of seagrasses, mangroves, salinity, depth, temperature, and mud. Estimates of total instantaneous mortality rates for YOY spotted seatrout in Tampa Bay were 0.027·d^-1 for fixed sites and to 0.025·d^-1 for randomly selected sites.
