Abstract Bergmann's rule—which posits that larger animals live in colder areas—is thought to influence variation body size within species across space and time, but evidence for this claim is mixed. We used Bayesian hierarchical models test four competing hypotheses spatiotemporal 20 bat North America: (1) the heat conservation hypothesis, which increased facilitates (and traditional explanation mechanism underlying rule); (2) mortality increases susceptibility acute stress; (3) resource...
Dekay’s Brownsnake (Storeria dekayi) occurs across much of eastern North America, inhabiting diverse environments such as marshes, woodlands, woodland edges, and urban areas. In Nebraska, recent studies documented its presence beyond the extreme southeastern region state, indicating a potential range expansion to west north. Our study continues update distribution with four additional county records. Two counties, Franklin Harlan, represent farthest observations for in further likely...
European starlings (Sturnus vulgaris) were fed either a low‐ or high‐quality diet to test the effects of dietary quality on basal metabolic rate (BMR) and internal morphology. Basal did not differ significantly between two groups, but morphology differed greatly. Starlings low‐quality had heavier gastrointestinal tracts, gizzards, livers. breast muscles. maintained mass, while gained mass. Dry matter digestibility energy lower for diet, their food water intake greater than diet. The lack...
Summary Understanding an animal's ecology requires knowledge of how individual variation in behaviour and physiology interact with each other the environment that animal experiences. Environmental affects behaviour, but whether physiological performance also is poorly known. We studied a high‐altitude population Deer Mice ( Peromyscus maniculatu s) inhabiting cold enough above‐ground activity (behaviour) may be limited by thermogenic capacity (maximal rate oxygen consumption [ V o 2 max ]...
Understanding how environmental factors affect activity, number, and spatial distribution of bats in an area is necessary for interpreting capture rates assessing abundance. Over a 34-year period, we examined the relationship between amounts precipitation activity along canyon floor San Mateo Mountains New Mexico southwestern United States. For 1 night during each 19 summers, used identical sampling techniques to monitor this assemblage insectivorous bats. Years included droughts with...
Desert ecosystems have long served as model systems in the study of ecological concepts (e.g., competition, resource pulses, top-down/bottom-up dynamics). However, inherent variability availability deserts, and hence consumer dynamics, can also make them challenging to understand. Study a Chihuahuan desert ecosystem near Portal, Arizona began 1977. At this site, 24 experimental plots were established divided among controls manipulations. Experimental manipulations over years include removal...

Some granivorous rodents scatter hoard; they bury seeds in shallow pits throughout their territory. These buried caches can represent food stores for the hoarders, competitors, or a means of seed dispersal and propagation plants. Large numbers may be many an area; thus, fate has important consequences granivores, other animals, This study examined ability Ord's kangaroo rat (Dipodomys ordii) to exploit artificial different sizes, at 2 depths, substrates differing moisture content. Kangaroo...
The eastern fox squirrel (Sciurus niger) has continued to move westward along riparian corridors in the southwestern United States. This species is now established Arkansas River and its major tributaries southeastern Colorado. In addition, a population of S. niger exists northern New Mexico, this might be result natural expansion from populations Purgatoire
During colder months in temperate regions, non-migratory bats are suspected to remain relatively inactive during hibernation. I examined activity of November–March a region North America with moderate winter temperatures. Bats were captured nets over water and along flyways southern central New Mexico. In 47 nights, 401 individuals representing 12 species. Captures for 10 species represent records previously unknown outside roosts The western pipistrelle (Pipistrellus hesperus),...
During a 2-year study, we documented eight species of bats using bridges in the lower Rio Grande Valley New Mexico. Of 17 surveyed, 15 (88%) contained day-roosting and ≥8 (47%) maternity colonies with one or more species, including Arizona myotis (Myotis occultus), Yuma yumanensis), Brazilian free-tailed bat (Tadarida brasiliensis). The pallid (Antrozous pallidus), big brown (Eptesicus fuscus), silver-haired (Lasionycteris noctivagans), California californicus), fringed thysanodes) roosted...
Food-storage behaviors can be plastic for food-hoarding species. Some hibernating, granivorous rodents switch seasonally from scatter hoarding (storing food in small, separate caches) to larder (concentrating a central location). To date, little is known about seasonal of free-living that forage and store year-round (i.e., nonhibernators). Using direct observations, radiotelemetry, tracking with fluorescent powder, we discovered striking shift Ord's kangaroo rat (Dipodomys ordii),...
The Brazilian free-tailed bat (Tadarida brasiliensis) generally is considered a migratory species in western North America. Throughout the southwestern United States, however, winter records are known from many scattered locations. Here I report on T. brasiliensis exiting and entering cave southern New Mexico November to March. observed that colony of bats at Carlsbad Cavern was comprised males females different ages, February March, documented numbers individuals inhabiting cavern were much...
The general lack of trees in the Great Plains has limited colonization by eastern woodland mammals past, but recent expansion forests corridors along prairie waterways and towns enabled an assortment species to expand distributional ranges westward. evening bat (Nycticeius humeralis) historically occurred woodlands throughout United States. Following our capture first New Mexico, we updated range for this amassing records from published literature museum voucher west its historic 1981, last...
Thirteen species of bats occur in Nebraska, but limited information is available on those inhabiting southwestern parts the state. We investigated distribution, abundance, and reproductive activity 5 counties extreme Nebraska (Chase, Hays, Dundy, Hitchcock, Red Willow). From April 2007 to 2008, we deployed mist nets 15 occasions at 8 localities over Republican River its tributaries. captured 100 individuals representing species, including evening bat (Nycticeius humeralis), eastern red...
The northern long-eared myotis (Myotis septentrionalis) occurs across much of eastern North America and is listed as federally threatened in the United States due to pervasive population declines. Limited data are available about roosting behaviors for this imperiled species. We report on night-roosting under a bridge northwestern Nebraska. Grooming, short visits, feeding were most frequently observed behaviors. inactivity, nursing had longest durations, albeit all averaged <15 min per...
In North America, Nebraska represents part of the northwestern edge distribution for evening bat (Nycticeius humeralis). To date, little information on this bat's natural history has been published from state or other parts Great Plains. Here we report aspects its in 2 localities. late summer and early autumn 2006, documented individuals farther west (Harlan County) than previously reported determined that fed mainly Coleoptera Hymenoptera. bats appeared to migrate during September–early...
The eastern pipistrelle (Perimyotis subflavus) is relatively common and widespread throughout the United States. In recent decades, distribution of P. subflavus has expanded westward across Great Plains, little information exists on its natural history in this region. east central Nebraska, we monitored use a mine by pipistrelles for >1 year. A few males occupied roost summer, but during period hibernation (late September–early May), was used at least 30 individuals composed both sexes. Most...
