A Survey of Bats in Wayne National Forest, Ohio

Author Institution: Ohio Cooperative Wildlife Research Unit, The Ohio State UniversityDistribution, abundance, habitat selection, and activity of bats in Wayne National Forest, Ohio, were studied during the winters and summers of 1979 and 1980. Methods included winter surveys of abandoned mines and mist netting of riparian sites in summer. Four species of bats were found hibernating in 23 of 65 coal mine shafts examined, and big brown bats, Epteskus fuscus, were most abundant. Mines with long tunnel systems had significantly higher temperatures than those with shorter systems, but humidity did not differ between mine types. Big brown bats chose the cooler mines and in general showed the greatest tolerance of climatic extremes. Eight species of bats totaling 261 individuals were captured by mist netting at 163 riparian locations in 5 watersheds. Little brown bats, Myotis lucifugus, comprised 56% of all bats captured. Big brown bats (14%), eastern pipistrels, Pipistrellus subflavus (13%), and red bats, Lasiurus borealis (13%), were the next most abundant species in mist net samples. No Indiana bats, Myotis sodalis, were captured. Big brown bats preferred to forage in forested habitats. Activity for most species was highest soon after sunset, but activity in big brown bats peaked 0.5 hr later than in the other species

Effect of Ankle Taping and Bracing on Dynamic Balance and Perception of Stability

Ankle injuries are the most common injury associated with sports participation. A recent study examining NCAA injury data found that 14.9% of all injuries sustained in 15 intercollegiate sports were injuries to the ankle. Taping and bracing are commonly used measures to prevent and/or protect the ankle from injury. Patients often report a feeling of increased stability due to tape and/or brace, however previous studies examining the effect of ankle appliances on stability have produced conflicting results. The purpose of this study was to examine the effect of taping and bracing on dynamic stability, and the perception of stability with and without ankle taping and bracing during dynamic stability testing

NESTING OF GREATER SANDHILL CRANES ON SENEY NATIONAL WILDLIFE REFUGE

During 1987, 59 nests of 57 pairs of greater sandhill cranes (Grus canadensis tabida) were located, mainly from the air, on or near the Seney National Wildlife Refuge, Michigan, and 52 nests were ground-checked. Nests were in available palustrine classes without tree canopies. Only 19% were in Sphagnum bogs, in which most nests from other areas of the Upper Peninsula have been found. Cattail (Typha latifolia) marshes, most prevalent in the managed area of the refuge, contabed 44% of the nests, and sedge (Carex spp.) marshes accounted for 37%. Important co-dominant plant species were leatherleaf (Chamaedaphne calyculata), especially in bogs and sedge marshes, and willows (Salix ssp. Carex) in cattail and sedge marshes, sometimes forming shrub swamps. An estimated 33 of 52 clutches (63%) successfully hatched at least one chick. Thirteen clutches (25%) were believed destroyed by predators. Predation rate was least in sedge marshes, but differences in water depth, concealment, shrub cover, and distance from nearest upland were not statistically significant between sites of depredated and non-depredated nests. Nests of 30 pairs were found in an 11,600-ha intensively studied area in the eastern part of the refuge. An estimated 50 breeding pairs occur in this area, a density of 0.43 pairs/km2. The population has increased in recent history, and available nesting habitat is not a limiting factor to a larger nesting population

Population Ecology of Common Gallinules in Southwestern Lake Erie Marshes

Author Institution: Ohio Cooperative Wildlife Research Unit, The Ohio State UniversityPopulation size, distribution, reproduction, and habitat selection of common gallinules (Gallinula chloropus) were studied in 1977-78 in the southwestern Lake Erie marshes in Ohio. Gallinules were censused by playing a tape-recorded call and counting the number of individuals responding within a 40-m radius. Eight to 30 of these 0.5-ha circular plots were placed randomly in each of 16 marsh habitats. The frequency of nonresponse was estimated from the responses of pairs with known locations, and estimates were corrected for nonresponse. Nest-density estimates from strip-transects were not different (P > 0.05) from pair-density estimates based on calling males. Pair-density estimates ranged from 0.2 to 4.6 pairs per ha. The population for 1978 was estimated to be 1,197 ± 149 pairs in 5,188 ha of wetland. Clutch size averaged 8.04 ± 0.56 eggs for 55 clutches, and 77% of 61 nests hatched at least 1 egg. Twenty-eight brood counts averaged 3.6 ± 0.6 fledged young. Gallinule densities were highest on semipermanently flooded wetlands with narrow-leaved, persistent emergent vegetation, an abundance of submergent aquatic plants, and a 1:1 ratio of cover to open water
