Assessing Plant Community Changes over Sixteen Years of Restoration in a Remnant Michigan Tallgrass Prairie
ABSTRACT.-Evaluating the progress of ecological restoration projects is critical to improving our understanding of degraded ecosystems and their rehabilitation. In a remnant tallgrass prairie in southeast Michigan that is being managed by periodic dormant-season...
Assessing the Responses of Native Small Mammals to an Incipient Invasion of Beech Bark Disease through Changes in Seed Production of American Beech (Fagus Grandifolia)
ABSTRACT.-Exotic tree diseases have direct impacts on their host and may have indirect effects on native fauna that rely on host tree species. This paper reports on relative preference for European beech [Fagus sylvatica (L.)] and sugar maple [Acer saccharum...
Avian Response to Mid-Contract Management of Conservation Reserve Program Fields
ABSTRACT.-Throughout the Midwestern U.S., grassland birds have been declining faster than any other group of birds, with the main cause for these declines being the extensive loss of native prairies. During the last 25 y, surrogate grasslands, such as...
Diet of Hoary (Lasiurus Cinereus) and Silver-Haired (Lasionycteris Noctivagans) Bats While Migrating through Southwestern Alberta in Late Summer and Autumn
ABSTRACT.-The feeding habits of hoary (Lasiurus cinereus) and silver-haired (Lasionycteris noctivagans) bats have been documented for their summer grounds, but little is known about their feeding habits while en route during migration. We analyzed stomach...
Distribution and Habitat Attributes of an Endemic Subspecies of Pocket Gopher
ABSTRACT.-Ozark pocket gophers, Geomys bursarius ozarkensis, are endemic to Izard County, Arkansas with a distribution of ~2300 km^sup 2^. Limited data exists on this subspecies; thus, we collected vegetation and soil habitat data within the current...
Habitat Characteristics and Revised Gap Landscape Analysis for the Northern Flying Squirrel (Glaucomys Sabrinus), a State Endangered Species in Pennsylvania
ABSTRACT.-We quantified the habitat characteristics associated with capture sites (2003-2006) of the state endangered northern flying squirrel (Glaucomys sabrinus) in Pennsylvania to develop management recommendations that help ensure its continued persistence...
Habitat Use by Fishes in Groundwater-Dependent Streams of Southern Oklahoma
ABSTRACT.-Habitat use by fishes in groundwater-dependent ecosystems with springs and spring-fed creeks is not widely studied or well understood. We evaluated habitat use by three disjunct populations of fish species (Phoxinus erythrogaster, Nocomis asper...
Natural History Informing Research: A Review of the Freshwater Mussels of Ohio

Niche Partitioning of the Sympatric Yellowcheek Darter Etheostoma Moorei and Rainbow Darter Etheostoma Caeruleum in the Little Red River, Arkansas
ABSTRACT.-We studied how habitat selection influences the distribution and densities of a stenotypic yellowcheek darter Etheostoma moorei (Raney and Suttkus) and eurytypic rainbow darter E. caeruleum (Storer) in a headwater stream subjected to periodic...
Replacing Hay-Mowing with Prescribed Fire Restores Species Diversity and Conservation Value in a Tallgrass Prairie Sampled Thrice: A 59-Year Study
ABSTRACT.-We examined changes in plant species composition at Faville Prairie in southeastern Wisconsin, based on surveys in permanently-marked, 2 × 2 m quadrats in 1946-1948, 1976-1978 and 2005. Permanent quadrats were distributed across a wide soil...
Spatial Pattern of Summer Bat Mortality from Collisions with Wind Turbines in Mixed-Grass Prairie
ABSTRACT.-Spatial analysis that aims to identify site-specific hotspots of collision mortality from birds or bats striking wind turbines can potentially lead to mitigating measures that reduce mortality rates. During May-Jul. 2004 and 2005, we studied...
Sympatric Sister Species of Californian Antirrhinum and Their Transiently Specialized Pollinators
ABSTRACT.-We investigated pollinator response to a pair of sympatric sister taxa, Antirrhinum subcordatum and A. vexillo-calyculatum (Plantaginaceae) . These two taxa, native to northern California, have overlapping geographic distributions, show specialization...
Temporal Patterns in Capture Rate and Sex Ratio of Forest Bats in Arkansas
ABSTRACT.-We quantified changes in capture rates and sex ratios from May to Sept. for eight species of bats, derived from 8 y of extensive mist netting in forests of the Ouachita Mountains, Arkansas. Our primary goal was to determine patterns of relative...
The Effect of Periodical Cicadas on Growth of Five Tree Species in Midwestern Deciduous Forests
ABSTRACT.-Periodical cicada emergences in the eastern United States are one of the largest biomass fluctuations in the world, providing a unique opportunity to study if a root parasite can affect broad-scale patterns of forest growth and succession....
