An Assessment of Distribution Patterns of Terrestrial Salamanders in the Central Appalachians Using Two Landscape Models
Read preview
ABSTRACT.-Conservation of terrestrial salamanders requires consideration for landscape-level features and processes; and, therefore, tools are needed to support planning at large spatial scales. We assessed terrestrial salamander distribution patterns...
Antipredator Responses of Larval Black Flies (Simulium Vittatum S. S.) to Chemical Stimuli from Damaged Conspecifics
Read preview
ABSTRACT.-Simulium larvae perform two behaviors in response to physical contact with invertebrate predators: curling and drifting. Curling involves the attachment of a silk thread to the substrate (in preparation for drifting), and drifting allows an...
Body Condition of a Free-Ranging Little Brown Bat (Myotis Lucifugus) with a Broken Humerus
Read preview
ABSTRACT.-We captured a free-ranging adult female little brown bat (Myotis lucifugus) with a fractured humerus that was in an advanced stage of healing. Compared to seven other adult female little brown bats captured the same evening from the same colony,...
Diet Resource Partitioning between the Golden Mouse (Ochrotomys Nuttalli) and the White-Footed Mouse (Peromyscus Leucopus)
Read preview
ABSTRACT.-Peromyscus leucopus and Ochrotomys nuttalli, two small mammal species of similar life histories and body mass, exhibit a high degree of sociality and niche overlap. We investigated differences in diet preference (ingested energy, protein content...
Distribution and Host Range of a Powdery Mildew Fungus Infecting Garlic Mustard, Alliaria Petiolata, in Southwestern Ohio
Read preview
ABSTRACT.-Garlic mustard is an invasive Eurasian biennial that has rapidly spread throughout the United States. In Southwestern Ohio, many garlic mustard populations are infected with Erysiphe cruciferarum, a causal agent of powdery mildew disease in...
Diversity, Seasonal Activity and Habitat Associations of Robber Flies (Diptera: Asilidae) in West-Central Illinois
Read preview
ABSTRACT.-Robber fly diversity, seasonal activity and habitat associations were studied in prairie and forest habitats in west-central Illinois from May to Oct. 2005. The greatest numbers of individuals and species were collected in recently burned prairie...
Drought Effect on Selection of Conservation Reserve Program Grasslands by White-Tailed Deer on the Northern Great Plains
Read preview
ABSTRACT.-Limited information exists regarding summer resource selection of white-tailed deer (Odocoileus virginianus) in grassland regions of the Northern Great Plains. During summers 2005-2006, we analyzed habitat selection of adult female white-tailed...
Effects of Prescribed Burning on Ant Nesting Ecology in Oak Savannas
Read preview
ABSTRACT.-Oak savannas in the Midwestern United States are rare ecosystems heavily altered by human activity. Common land management practices, like prescribed fire can control invasive species and restore native plants, but few studies have examined...
Food Habits and Dietary Overap of Two Silversides in the Tennessee-Tombigbee Waterway: The Invasive Menidia Audens versus the Native Labidesthes Sicculus
Read preview
ABSTRACT.-The Mississippi silverside (Menidia audens), now common throughout the Tennessee-Tombigbee Waterway (TTW) in Mississippi, apparently invaded this highly modified system from the Tennessee River, concurrent with TTW construction (1972-1985)....
Guilty in the Court of Public Opinion: Testing Presumptive Impacts and Allelopathic Potential of Ranunculus Ficaria
Read preview
ABSTRACT.-Information about invasive species is often based primarily on anecdotal evidence, indicating the need for further information. Ranunculus ficaria is an ephemeral riparian plant species that is presumed invasive in the United States, despite...
Influence of Invasive Earthworms on above and Belowground Vegetation in a Northern Hardwood Forest
Read preview
ABSTRACT.-Scientists are beginning to have a firm grasp on the dramatic influence invasive earthworms can have on nutrient cycling in northern hardwood forests, yet a concrete understanding of their effects on plant communities is still needed. Towards...
Mycorrhizal Fungi from Protocorms, Seedlings and Mature Plants of the Eastern Prairie Fringed Orchid, Platanthera Leucophaea (Nutt.) Lindley: A Comprehensive List to Augment Conservation
Read preview
ABSTRACT.-The Federally threatened Eastern Prairie Fringed Orchid, Platanthera leucophaea (Nutt.) Lindley (Orchidaceae), has experienced long-term decline largely due to habitat loss and degradation. Although this species has been propagated from seed...
On Preserving Knowledge
Read preview
ABSTRACT.-New knowledge in science is built on previous knowledge. Thus, the primary purpose of preserving scientific knowledge is that future scientists will be able collate said knowledge years from now to answer questions not yet asked. Secondarily,...
Palatability of Twelve Species of Anuran Larvae in Eastern Texas
Read preview
ABSTRACT.-We tested the palatability of 12 species of anuran larvae that occur in eastern Texas using four common predators. Palatability was determined by offering larvae to predators and recording the behavior of the predator. We also tested for ontogenetic...
Response of Rodents to Wildfire and Livestock Grazing in an Arizona Desert Grassland
Read preview
ABSTRACT.-Livestock grazing and fire influence the composition of desert grassland communities, including their rodent populations. However, there have been few studies of the interactions between grazing and wildfire in arid grasslands of the southwestern...
Responses of Small Mammals and Vegetation to a Prescribed Burn in a Tallgrass Blackland Prairie
Read preview
ABSTRACT.-This study investigated effects of a prescribed bum on the small mammal community and vegetative cover in a tallgrass prairie remnant in east central Texas. Small mammals were live-trapped 8 mo before and 8 mo after a prescribed burn. Vegetation...
Scale-Dependent Factors Affecting North American River Otter Distribution in the Midwest
Read preview
ABSTRACT.-The North American river otter (Lontra canadensis) is recovering from near extirpation throughout much of its range. Although reintroductions, trapping regulations and habitat improvements have led to the reestablishment of river otters in...
Terrestrial Macrofungi of Illinois Old-Growth Prairie Groves
Read preview
ABSTRACT.-Macrofungi from two old-growth prairie grove remnants in the Midwestern United States (Brownfield and Trelease Woods, Champaign Co., IL ) were surveyed over two summer and fall fruiting periods. Communities of Ascomycetes, Basidiomycetes and...
The Use of Scales to Estimate the Prey Size of Nearctic River Otters (Lontra Canadensis) and Other Piscivores
Read preview
ABSTRACT.-Estimating the size of fish prey requires the use of relationships between the size of non-digestible fish remains (recovered as prey in scats or digestive tracts) and fish length. The applicability of scales for estimating the size of fish...
