Whipspiders (Arachnida: Amblypygi) in amber from the Early Eocene and mid-Cretaceous, including maternal care
(University of Kansas, 2014-08-06)Two new genera and species of fossil whipspiders (Chelicerata: Arachnida: Amblypygi) are described from Tertiary and Cretaceous ambers of southern Asia. Paracharonopsis cambayensis Engel & Grimaldi, new genus and species, ... -
Climate Change Influences on Global Distributions of Dengue and Chikungunya Virus Vectors
(Philosophical Transactions of the Royal Society, 2014)This packet presents raster data files that accompany a manuscript submitted for publication to Philosophical Transactions of the Royal Society, titled “Climate Change Influences on Global Vector Distributions for Dengue ... -
An Analysis of Factors Affecting the Oxygen Consumption of the Isopod Ligia oceanica
(University of Chicago Press, 1997-01-01)A multiple-regression equation was derived in which the statistical significance of the effects of six independent variables on metabolic rate could be arranged in the following order: exposure temperature, body weight, ... -
Yellow-bellied marmot population dynamics: demographic mechanisms of growth and decline
(2004-09-01)Multiple environmental factors may act synergistically to influence demographic characteristics, and ultimately the dynamics, of biological populations. Using prospective and retrospective analyses of demographic data from ... -
Spatiotemporal variation in survival rates: implications for population dynamics of yellow-bellied marmots
(Ecological Society of America, 2006-04-01)Spatiotemporal variation in age-specific survival rates can profoundly influence population dynamics, but few studies of vertebrates have thoroughly investigated both spatial and temporal variability in age-specific survival ... -
Socioecology of Marmots: Female Reproductive Strategies
(Ecological Society of America, 1976-05-01)The relationship between female reproductive success and both spring food and hibernacula resources was examined in a high-altitude population of yellow-bellied marmots (Marmota flaviventris). The number of offspring a ... -
Mirror-Image Stimulation Applied to Field Behavioral Studies
(Ecological Society of America, 1973-05-01)Twenty-nine adult and yearling marmots were exposed to mirror-image stimulation. Marmots interacted intensely with their image, and the frequency of occuranaces of 22 behaviors was recorded. The four factors extracted from ... -
Individuality, Social Behavior, and Reproductive Success in Yellow-Bellied Marmots
(Ecological Society of America, 1986-10-01)Current theory suggests that population dynamics are the consequence of the reproductive strategies of individuals. Individual differences should be expressed in reproductive output, dispersal, social behavior, and ... -
Energetics of Yellow-Bellied Marmot Populations

Ecology of Zooplankton of the Cape Thompson Area Alaska
(Ecological Society of America, 1967-01-01)In a survey of the physicochemical characteristics, primary productivity and occurrence of zooplankton in fresh and brackish waters of Cape Thompson, Alaska, between June 28, 1960 and August 7, 1961, 14 species of Cladocera ... -
Ecology of the Riffle Insects of the Firehole River, Wyoming
(Ecological Society of America, 1958-10-01)An abstract for this item is not available. -
Demography of Yellow-Bellied Marmont Populations
(Ecological Society of America, 1974-11-01)Marmot (Marmota flaviventris) populations are colonial or satellite. The number of adults of colonial populations is relatively stable; fluctuations occur primarily because of changes in numbers of young and yearlings. ... -
Disease in Natural Plant Populations, Communities, and Ecosystems: Insights into Ecological and Evolutionary Processes
(The American Phytopathological Society, 2010-05-01) -
Barley Yellow Dwarf Disease in Natural Populations of Dominant Tallgrass Prairie Species in Kansas
(American Phytopathological Society, 2004-05-01)The grasses Sorghastrum nutans (Indian grass), Schizachyrium scoparium (little bluestem), Panicum virgatum (switchgrass), and Andropogon gerardii (big bluestem) are four of the most common plant species present in a tallgrass ... -
Virulence changes in Uromyces appendiculatus after five asexual generations on a cultivar of bean (Phaseolus vulgaris)
(American Phytopathological Society, 1985-01-01)A field population of Uromyces appendiculatus, the bean rust pathogen, was obtained from the susceptible cultivar Pinto 111 in southwestern Minnesota, and maintained for five asexual generations on a partially resistant ... -
Pathogenicity associations in Puccinia graminis f. sp. tritici in the United States
(American Phytopathological Society, 1984-01-01)Associations of pathogenicity in predominantly asexually reproducing populations of Puccinia graminis f. sp. tritici were analyzed for eight selected years between 1929 and 1978 on 10 standard differential wheat lines. In ... -
The Distribution of Mating-Type Bias in Natural Populations of the Anther-Smut Ustilago violacea on Silene alba in Virginia
(Ecological Society of America, 1998-05-01)Complete individual-wide mating-type bias (retrieval of sporidia of only one mating type from germinated teliospores of one fungal individual) was observed to be a common and widespread feature of the anther-smut fungus, ... -
Population Dynamics and Genetics of Plant Disease: A Case Study of Anther-Smut Disease
(Ecological Society of America, 1996-06-01)A model by Levin and Udovic (1977) emphasizes the need for integration of studies of the numerical abundances and genetic composition of host and pathogen species. We use their conceptual framework to summarize our ... -
Estimation of population size and probabilities of survival and detection in a population of Mead’s milkweed
(Ecological Society of America, 2003-03-01)Statistical similarities exist between estimating numbers of cryptic animals and of inconspicuous plants. Without flowers, Mead's milkweed (Asclepias meadii) is an unobtrusive prairie plant, and most plants flower irregularly. ... -
Dispersal and disease gradients of anther-smut (Ustilago violacea) infection of Silene alba at different life stages
(Ecological Society of America, 1995-09-01)Given the increased recognition of the importance of spatial aggregation of infected individuals on disease spread, we used a field experiment to examine spore dispersal and disease transmission at increasing distances ...
