Food habits of Nyctinomops macrotis at a maternity roost in New Mexico, as indicated by analysis of guano Food habits of Nyctinomops macrotis at a maternity roost in New Mexico, as indicated by analysis of guano
We examined 56 fecal pellets from under a maternity colony of big free-tailed bats (Nyctinomops macrotis) in the Jemez Mountains of northern New Mexico. The most important food items, listed in order of decreasing percent volume, were Cicadellidae, leafhoppers (26.7% volume, 58.9% frequency); Ichneumonidae, Ichneumon wasps (19.3% volume, 35.7% frequency); and Lepidoptera, moths (17.2%...

Treatment of black-tailed prairie dog burrows with deltamethrin to control fleas (Insecta: Siphonaptera) and plague Treatment of black-tailed prairie dog burrows with deltamethrin to control fleas (Insecta: Siphonaptera) and plague
Burrows within black-tailed prairie dog (Cynomys ludovicianus) colonies on the Rocky Mountain Arsenal National Wildlife Refuge, Colorado, were dusted with deltamethrin insecticide to reduce flea (Insecta: Siphonaptera) abundance. Flea populations were monitored pre- and posttreatment by combing prairie dogs and collecting fleas from burrows. A single application of deltamethrin...

A national survey of Conservation Reserve Program (CRP) participants on environmental effects, wildlife issues, and vegetation management on program lands A national survey of Conservation Reserve Program (CRP) participants on environmental effects, wildlife issues, and vegetation management on program lands
A national survey of Conservation Reserve Program (CRP) contractees was completed to obtain information about Abstract environmental and social effects of the program on participants, farms, and communities. Of interest were observations concerning wildlife, attitudes about long-term management of program lands, and effectiveness of U.S. Department of Agriculture (USDA) assistance in...

Bats of the piñon-juniper woodlands of southwestern Colorado Bats of the piñon-juniper woodlands of southwestern Colorado
As one of the most abundant and widespread forest types in the Southwest, piñon-juniper woodlands are used to varying degrees by many bat species (Chung-MacCoubrey 1996; Findley et al. 1975; Hoffmeister 1986; Jones 1965). Because of the uniqueness and rarity of old-growth piñon-juniper, the ancient woodlands of Mesa Verde Country likely provide bats with a combination of roosting and...

Western crevice and cavity-roosting bats Western crevice and cavity-roosting bats
Among the 45 species of bats that occur in the United States (U.S.), 34 species regularly occur in western regions of the country. Many of these “western” species choose roost sites in crevices or cavities. Herein we provide an introduction to the biology of bats that roost in cavities and crevices and assess the challenges and opportunities associated with monitoring their populations...

The effects of bird use on nutrient removal in a constructed wastewater-treatment wetland The effects of bird use on nutrient removal in a constructed wastewater-treatment wetland
A 9.9-ha constructed wetland designed to reduce nitrogen in municipal wastewater following conventional secondary treatment began operating in southern California's San Jacinto Valley in September 1994. The wetland incorporated zones of bulrush (Schoenoplectus acutus and S. californicus) for effluent treatment, plus areas of 1.8-m deep open water and other features to benefit wintering...

Reconnaissance-level application of physical habitat simulation in the evaluation of physical habitat limits in the Animas Basin, Colorado Reconnaissance-level application of physical habitat simulation in the evaluation of physical habitat limits in the Animas Basin, Colorado
The Animas River is in southwestern Colorado and flows mostly to the south to join the San Juan River at Farmington, New Mexico (Figure 1). The Upper Animas River watershed is in San Juan County, Colorado and is located in the San Juan Mountains. The lower river is in the Colorado Plateau country. The winters are cold with considerable snowfall and little snowmelt in the mountains in the...

Soil characteristics and plant exotic species invasions in the Grand Staircase-Escalante National Monument, Utah, USA Soil characteristics and plant exotic species invasions in the Grand Staircase-Escalante National Monument, Utah, USA
The Grand Staircase - Escalante National Monument (GSENM) contains a rich diversity of native plant communities. However, many exotic plant species have become established, potentially threatening native plant diversity. We sought to quantify patterns of native and exotic plant species and cryptobiotic crusts (mats of lichens, algae, and mosses on the soil surface), and to examine soil
