|Axle grease as an alternative adhesive for use on sticky traps.
||One of the more frequently used methods of sampling flying insects is the sticky trap. These traps are often used to evaluate the type and size of prey available for aerial insec-tivores, such as bats and birds (e.g. Barclay 1991; Brigham 1992). Non-...
| Bat Activity in the Boreal Forest: Importance of Stand Type and Vertical Strata
||We examined habitat use by bats in the boreal forest of central Saskatchewan during summer
1995 by monitoring echolocation calls across forest types and through the canopy of
mature forest. We sampled bat activity in mature aspen (Populus tremul...
|Bats and the loss of tree canopy in African woodland.
||We studied the activity patterns, abundance, diversity, and diets of bats, along with the abundance of nocturnal volant insects, at 30 sites in Miombo woodland in northern Zimbabwe. The woodland at 50% of the sites had been disturbed by high elephant...

|Can External Radiotransmitters be used to Assess Body Temperature and Torpor in Bats?
||We tested externally applied, temperature-sensitive, radiotransmitters for determining the
body temperature of big brown bats (Eptesicus fuscus) in various ambient temperatures (2-

|Differences in Ultrasonic Vocalizations between Wild and Laboratory California Mice (Peromyscus californicus)
||Background: Ultrasonic vocalizations (USVs) emitted by muroid rodents, including laboratory mice and rats, are used as phenotypic markers in behavioral assays and biomedical research. Interpretation of these USVs depends on understanding the signific...
|Effect of fluorescent powder marking of females on mate choice by male white-footed mice (Peromyscus leucopus).
||Although fluorescent powder marking is a well established and common marking technique used by small-mammal ecologists, few studies have commented on how it might affect behavior. Potential effects on behavior are particularly relevant in studies tha...
|Effect of Removal of Woody Biomass after Clearcutting and Intercropping Switchgrass (Panicum virgatum) with Loblolly Pine (Pinus taeda) on Rodent Diversity and Populations
||Plant-based feedstocks have long been considered viable, potential sources for biofuels. However, concerns regarding production effects may outweigh gains like carbon savings. Additional information is needed to understand environmental effects of gr...
|Effects of wastewater treatment plant effluent on bat foraging ecology in an urban stream system.
||Wastewater treatment plant (WWTP) effluent in the Cape Fear River Basin headwaters in North Carolina, USA, has influenced stream water quality and aquatic components of the stream food web. To examine effects of WWTP effluent on terrestrial predators...
|Elephants, woodlands and biodiversity in southern Africa.
||When elephant densities exceed approximately 0.5 per km, savanna woodlands are generally converted to shrub-lands or grasslands. The impact of such elephant-mediated habitat change on biodiversity in African game reserves has seldom been measured....
|A genetic analysis of group movement in an isolated population of tree-roosting bats
||Group fission is an important dispersal mechanism for philopatric adults. In Cypress Hills Interprovincial Park, Saskatchewan, tree-roosting big brown bats (Eptesicus fuscus) exhibit fission–fusion roosting behaviour. During 2004–2007, the majority o...
|Genetic relationships of roost-mates in a fission-fusion society of tree-roosting big brown bats.
Kin-based patterns of associations are often observed in group living mammals. Colonies of forest-living big brown bats (Eptesicus fuscus) exhibit fission–fusion roosting behavior and female philopatry. Within a roosting area of forest, ad...
|Impact of predation risk on emergence by little brown bats, Myotis lucifugus (Chiroptera: Vespertilionidae), from a maternity colony.
||When bats emerge from their roosts in the evening to forage and drink, it appears as though their departure involves brief periods when many individuals emerge interspersed with periods during which few individuals emerge. Clustering is seen in many ...
|Intercropping Switchgrass with Loblolly Pine Does Not Influence the Functional Role of the White-footed Mouse (Peromyscus leucopus)
||Intercropping biofuel feedstocks in managed forests of the southeastern United States is a potentially sustainable source of renewable energy. Ecological effects of energy crops in forests are poorly understood, and it is unknown whether the ecologic...
|Intraspecific Variation in Roost-site Selection by Little Brown Bats (<i>Myotis lucifugus</i>)
||Although many species of bats select roost sites in large trees that are in
open areas, intraspecific variation in roost-site selection may exist. We collected
data on the roosting behaviour of little brown bats in the Cypress
|Intraspecific variation in wing loading affects habitat use by little brown bats (Myotis lucifugus).
||Morphological constraints have been linked to habitat partitioning by different species of animals. Interspecific differences have been explored, but less is known about the relationship between individuals of the same species. The purpose of this st...
||Lavia frons (Fig. 1) is distinguished from all
other African bats except Cardioderma cor in having a large, erect
noseleaf, a divided tragus, and large ears that are basally united
across the top of the head. Lavia frons diffe...
|Male fidelity expressed through rapid testosterone suppression of ultrasonic vocalizations to novel females in the monogamous California mouse
||The steroid hormone testosterone (T) is a well-known mediator of male sexual behavior in vertebrates. However, less is known about T's rapid effects on sexual behavior, particularly those involving ultrasonic vocalizations (USVs), a mode of communica...
|Medium-and long-term reuse of trembling aspen cavities as roosts by big brown bats (Eptesicus fuscus)
||Roost availability may limit some bat populations, implying that there may be a selective advantage associated with the ability to reuse sites on an annual basis. We monitored aspen tree use by Eptesicus fuscus during multi-year studies (spann...

||Although losses of Common Poorwill (Phalaenoptilus nuttallii) nests to predators are common, little is known about predation on adults. Remains of three adults, radio-tagged in Cypress Hills Provincial Park, Saskatchewan, were found. The transmitter ...
|Production of ultrasonic vocalizations by Peromyscus mice in the wild.
||Background: There has been considerable research on rodent ultrasound in the laboratory and
these sounds have been well quantified and characterized. Despite the value of research on
ultrasound produced by mice in the lab, it is unclear if, and whe...
|Relationships of Basal Metabolism and Life History Attributes in Neotomine-Peromyscine Rodents (Cricetidae: Neotominae).
