Fleas (Siphonaptera) In Nests Of Voles (Microtus Spp.) In Montane Habitats Of Three Regions Of Utah, Glenn E. Haas, James R. Kucera

Western North American Naturalist

As a parallel study of a survey of fleas of trapped small mammals in montane southern Utah, we removed 77 adult fleas from 12 of 13 nests of voles (Microtus longicaudus, M. montanus and M. richardsoni) collected from montane meadows in the Abajo and La Sal Mountains, the Markagunt Plateau and Pine Valley Mountains, and the Uinta Mountains, May 1991–July 2002. Six species and subspecies of fleas parasitic on Microtus spp. were found, 1–3 species in each nest. Three specimens of the ubiquitous deer mouse (Peromyscus spp.) flea Aetheca wagneri (Baker) were also found. We collected the …

Growth And Yield Of Black Spruce, Picea Mariana (Mill.) B.S.Pl., In Alaska, Carolyn Rosner

Forest Sciences

Black spruce, Picea mariana (Mill.) B.S.P., is largely overlooked in Alaska because of its small size and slow growth. Growth and yield information is therefore limited or nonexistent. Presented here are the first polymorphic site index (height-age) curves and height-diameter functions for predicting height and volume for Alaska black spruce. Models are accurate for trees up to 50 feet in height and 8 inches DBH. Predicted stem volumes range from 0.006 ft3 to 21.8 ft3 for trees between 0.5 and 11.5 inches DBH Sampled tree dimensions range from 5.5 to 78.0 feet tall and from 0.4 to 11.0 inches DBH. …

Kelp Bed Variability And Fish Population Dynamics In Kachemak Bay, Alaska, Judith Ann Hamilton

Marine Biology

Understanding interactions between kelp beds and fishes is essential because anthropogenic changes and natural variability in these beds (composition, density, and distribution) may affect available habitat for fishes. In Alaska, little is known about the annual and seasonal variability of macroalgal cover in kelp beds and corresponding changes in associated fish populations. This study investigated natural variability using monthly SCUBA surveys in Kachemak Bay, Alaska from May 2002 to September 2003. Ten shallow (approximately 7m water depth) nearshore kelp beds with varying degrees of macroalgal cover were surveyed visually for fishes and kelp, and measurements of environmental variables were collected. …

Asner, Rob Braswell, Mercedes Bustmante, Eric A. Davidson, Ted Feldpausch, Erick Fernandes, M L. Goulden, Paval Kabat, Bart Kruijt, Flavio Luizao, Scott Miller, Daniel Markewitz, Antonio D. Nobre, Carlos Nobre, Nicolau Priante Filho, Humberto Da Rocha, Pedro Silva Dias, Celso Von Randow, George Vourlitis

Earth Sciences

The Large-scale Biosphere–Atmosphere Experiment in Amazonia (LBA) is a multinational, interdisciplinary research program led by Brazil. Ecological studies in LBA focus on how tropical forest conversion, regrowth, and selective logging influence carbon storage, nutrient dynamics, trace gas fluxes, and the prospect for sustainable land use in the Amazon region. Early results from ecological studies within LBA emphasize the variability within the vast Amazon region and the profound effects that land-use and land-cover changes are having on that landscape. The predominant land cover of the Amazon region is evergreen forest; nonetheless, LBA studies have observed strong seasonal patterns in gross primary …

Demography And Genetic Structure Of An Allegheny Woodrat Population In Northcentral West Virginia, Mary Elizabeth Manjerovic

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Allegheny woodrat (Neotoma magister) occurs throughout the Appalachian Mountains forming isolated colonies in rock outcrops, cliffs, and caves. In the past 20--30 years, populations along the northern and western peripheries of the range have experienced drastic declines. There have been suggested reasons for this decline but a lack of long-term data has prevented application of specific management actions. In recent years, there has been more insight into population structure, gene flow, and relatedness among colonies. The objectives of my study were to examine these factors at a localized level to further assist with future management decisions.;Using data collected over …

Retrospective Isotopic Analyses Of Stellar Sea Lion Tooth Annuli And Sea-Bird Feathers: A Cross-Taxa Approach To Investigating Regime And Dietary Shifts In The Gulf Of Alaska, Keith Hobson, Elizabeth Sinclair, Anne York, James Thomason, Richard Merrick

United States Department of Commerce: Staff Publications

Stable isotope (δ¹⁵N and δ¹³C) values of individual tooth annuli of female Steller sea lions (n = 120) collected from the 1960s through the 1980s were used for retrospective analyses of temporal changes in food webs in the Gulf of Alaska and North Pacific Ocean. We also examined isotopically contour feathers of tufted puffins (n = 135) and crested auklets (n = 37) through this period to test for broader isotopic patterns indicative of whole food web changes. Steller sea lions decreased slightly in δ¹³C and increased in δ¹⁵N values, suggesting an …

On The Local Coexistence Of Species In Plant Communities, J. Yoshimura, K. Tainaka, M. Shiyomi, T. Suzuki

International Congress on Environmental Modelling and Software

Coexistence of many competitive species is very common in natural plant communities. For example, almost all forests and grasslands consist of various species. Extremely high biodiversity is seen in tropical rain forests. Grassland communities also often consist of many species. In plant communities, spatially competitive species of plants coexist in a mosaic pattern. Communities with a single species are very extremely rare in nature. However, mathematical studies show that the local coexistence of spatially competitive species is rarely achieved even with two competitive species. Many studies have introduced external factors to promote coexistence, such as immigration of seeds, seed dormancy, …

Predicting Predation Efficiency Of Biocontrol Agents: Linking Behavior Of Individuals And Population Dynamics, Brigitte Tenhumberg

International Congress on Environmental Modelling and Software

Behavioral ecology and population ecology are two separate branches of ecology; studies linkingthe effect of individual behavior and population dynamics are rare. This paper connects a stochastic optimalforaging model of insect predators with an age structured population model of its prey. I modeled syrphidlarvae feeding on cereal aphids, an interaction critical to cereal crops in Germany. The key stochastic elementin this model is the foraging success of predators, which influences survival and developmental time ofpredators and mortality of the prey population. The model predicts that the level of control incurred bypredators is highest if predators arrive when prey numbers are …

Molecular Analysis Of Carbon Monoxide-Oxidizing Bacteria Associated With Recent Hawaiian Volcanic Deposits, Kari E. Dunfield, Gary M. King

Faculty Publications

Genomic DNA extracts from four sites at Kilauea Volcano were used as templates for PCR amplification of the large subunit (coxL) of aerobic carbon monoxide dehydrogenase. The sites included a 42-year-old tephra deposit, a 108-year-old lava flow, a 212-year-old partially vegetated ash-and-tephra deposit, and an approximately 300-year-old forest. PCR primers amplified coxL sequences from the OMP clade of CO oxidizers, which includes isolates such as Oligotropha carboxidovorans, Mycobacterium tuberculosis, and Pseudomonas thermocarboxydovorans. PCR products were used to create clone libraries that provide the first insights into the diversity and phylogenetic affiliations of CO oxidizers in situ. On the basis of …

Effects Of Natal Departure And Water Level On Survival Of Juvenile Snail Kites (Rostrhamus Sociabilis) In Florida, Victoria J. Dreitz, Wiley M. Kitchens, Donald L. Deangelis

Wildlife Biology Faculty Publications

Survival rate from fledging to breeding, or juvenile survival, is an important source of variation in lifetime reproductive success in birds. Therefore, determining the relation-ship between juvenile survival and environmental factors is essential to understanding fitness consequences of reproduction in many populations. With increases in density of individuals and depletion of food resources, quality of most habitats deteriorates during the breeding season. Individuals respond by dispersing in search of food resources. Therefore, to understand the influence of environmental factors on juvenile survival, it is also necessary to know how natal dispersal influences survival of juveniles. We examined effects of various …

Tide, Buoyancy, And Wind-Driven Circulation Of The Charlotte Harbor Estuary: A Model Study, Lianyuan Zheng, Robert H. Weisberg

Marine Science Faculty Publications

The circulation of the Charlotte Harbor (CH) estuary is explored with a primitive equation model that encompasses the estuary and the adjacent West Florida Shelf. Tidal forcing is from the shelf through the inlets. We use the M₂, S₂, K₁, and O₁ constituents that account for 95% of the shelf tidal variance. River inflows are by the Peace, Myakka, and Caloosahatchee Rivers at their spring 1998 mean values. Wind effects are considered for upwelling or downwelling favorable winds that are either held constant or allowed to oscillate with varying periodicities. These factors are …

Combining Paternally And Maternally Inherited Mitochondrial Dna For Analysis Of Population Structure In Mussels, Robert A. Krebs

Biological, Geological, and Environmental Faculty Publications

Sequence divergence for a fragment of the 16S rRNA gene was compared to identify the advantages in using mitochondrial genes that descend separately through the female and male lineages to examine population structure. The test compared divergence among four local species of freshwater mussels (Unionidae) and was extended to multiple populations of one species, Pyganodon grandis. For the same gene, the male-inherited sequences diverged at a faster rate, producing longer branch lengths in the phylogenies. Of particular use were sequences extracted from P. grandis populations from the southern region of the Lake Erie watershed (Ohio, USA); five male-inherited haplotypes were …

A Public Policy Toward The Management Of Feral Cats, Shawn Gorman, Julie Levy

The University of New Hampshire Law Review

[Excerpt] “This paper examines the current wildlife laws, both federal and state, to determine what laws may apply to managing the feral cat population. It begins with a determination of how domestic cats are classified under these laws. Since many laws are vague, the intent of the legislatures is investigated to determine if domestic cats were meant to be defined as a nonindigenous species. The focus then shifts to indicate ways to control the feral domestic cat population. Current trends in the control of other nonindigenous species appear to revolve around public nuisance claims; however, due to the unique nature …

The Impact Of Urbanization On Macroinvertebrate Communities Of Creeks Within Western Georgia, Jeniffer Susan Lang

Theses and Dissertations

Urbanization is a major cause of stream impairment in the United States, altering stream ecological integrity in a variety of ways. While control of point source pollution has largely improved over the last twenty years, the control of non-point source pollution has proved to be more of a challenge. Urbanization in the area surrounding streams has been linked with elevated levels of sediment, heavy metals, organic matter, and nutrients within streams, as well as with other negative effects. Examining the macroinvertebrate communities within streams has proven to be an effective indicator of the effects of urbanization on water quality. This …

Diploid And Polyploid Cytotype Distribution In Melampodium Cinereum And M. Leucanthum (Asteraceae, Heliantheae), Tod F. Stuessy, Hanna Weiss-Schneeweiss, David J. Keil

Biological Sciences

Previous chromosomal studies within Melampodium (Asteraceae, Heliantheae) of Mexico and Central America have documented chromosome numbers n = 9, 10, 11, 12, 18, 20, 23, 25 ± 1, 27, 30, and 33. Some species also have been shown to exhibit infra-and interpopulational polyploidy. The presence of cytotype mixtures is especially pronounced in the white-rayed complex, which occurs in the southwestern United States and adjacent Mexico. This group includes M. cinereum (n = 10 and 20), M. leucanthum (n = 10 and 20), and M. argophyllum (n = 30). Cytotype distribution has been newly analyzed in 415 plants from 152 populations …

Rationale For A New Generation Of Indicators For Coastal Waters, Gerald Niemi, Denice Wardrop, Robert Brooks, Susan Anderson, Valerie Brady, Hans Paerl, Chet Rakocinski, Marius Brouwer, Barbara Levinson, Michael Mcdonald

Faculty Publications

More than half the world'S human population lives within 100 km of the coast, and that number is expected to increase by 25% over the next two decades. Consequently, coastal ecosystems are at serious risk. Larger coastal populations and increasing development have led to increased loading of toxic substances, nutrients and pathogens with subsequent algal blooms, hypoxia, beach closures, and damage to coastal fisheries. Recent climate change has led to the rise in sea level with loss of coastal wetlands and saltwater intrusion into coastal aquifers. Coastal resources have traditionally been monitored on a stressor-by-stressor basis such as for nutrient …

Investigations Of The Role Of Lipids In Marine Mammal Diets, Health And Ecology, Tamara Lynn Mau

Marine Biology

Lipids are essential to many aspects of marine mammal biology. I investigated the amount, type and flux of lipids under a variety of natural and controlled nutritional and dietary conditions, in order to increase our knowledge of marine mammal diets, health and ecology. First, I examined the influence of biological and environmental variables on the quantity and quality of blubber, and their importance in establishing condition indices in the bowhead whale. Blubber was heterogeneous in composition, varying by both site and depth. Sex, age-class, season and body length were all significant factors in determining lipid content (quality) of blubber. Blubber …
