The Nebraska Game and Parks Commission (NGPC) contracted the Rainwater Basin Joint Venture (RWBJV) to conduct a black-tail prairie dog colony inventory of Nebraska using 1-meter National Agriculture Imagery Program ( 2010) aerial imagery. We estimated the extent of each colony by placing polygon vertices on the furthest visible burrows. Burrows were then re-evaluated using sub-meter resolution imagery. Burrow delineations within 3 kilometers of one another were combined and considered a single colony resulting in 669 distinct colonies totaling 97,438 acres across the state of Nebraska.
These data are comprised of measurements of gross alpha activity, gross beta activity, and radionuclide activities (isotopic U, isotopic Th, Ra-226) in small rodent bodies. Samples were collected at non-mining and U breccia pipe mining sites in various production stages, in the Grand Canyon watershed.

These data are comprised of histopathological analysis of liver and kidney tissues collected from small rodents collected in close proximity to brecchia pipe uranium mines in the Grand Canyon watershed.
Experiments were conducted to assess the influences of granivores on the seed bank in sagebrush-steppe. Rodent and/or ant exclosures were established at two distances from five harvester ant mounds. Monthly soil samples were collected from the exclosures, and from open access areas at two distances to ascertain changes in the seed bank. Seed dish experiments were conducted monthly to establish a maximum seed removal rate. Rodents were trapped monthly. More seeds were recovered from rodent exclosures than from ant exclosures. Seed banks changed temporally and spatially, with more seeds recovered in September and at 6 m from mounds. Rodents removed seeds more rapidly from seed dishes than did ants. Ants removed more...

This study addressed the initial effects of a reintroduction of Gunnison's prairie dogs (Cynomys gunnisoni) on resident small mammal and plant communities on the Sevilleta National Wildlife Refuge (SNWR), New Mexico. In spring 1997, 60 prairie dogs (36.8 kg live mass) were introduced onto a former prairie dog colony in a desert grassland site. Small mammals and vegetation were sampled on both a treatment (reintroduction site) and a control site (without prairie dogs) before and after the prairie dogs were reintroduced. We tested for differences in small mammal and plant community change during the 1st year of the colony's existence using repeated measures analysis of variance. Although prairie dog biomass was ca....

These data are comprised of measurements of aluminum, iron, cobalt, nickel, copper, zinc, arsenic, selenium, molybdenum, silver, cadmium, thallium, lead, bismuth, thorium, uranium, and mercury in soil, vegetation, and small rodents. Gross alpha activity, gross beta activity, and radionuclide activities (isotopic U, isotopic Th) are also presented for vegetation and soil. Radioactivities for small rodents were previously presented at https://doi.org/10.5066/P9HARTQ4. Samples were collected at the Kanab North Mine (post-mining, pre-reclamation) in the Grand Canyon watershed.

These data are comprised of measurements of aluminum, iron, cobalt, nickel, copper, zinc, arsenic, selenium, molybdenum, silver, cadmium, thallium, lead, bismuth, thorium, uranium, and mercury in invertebrates, vegetation, and small rodents. Gross alpha activity, gross beta activity, and radionuclide activities (isotopic U, isotopic Th) are also presented for vegetation; radioactivities for small rodents were previously presented at https://doi.org/10.5066/P9HARTQ4. Histopathology results are given for liver and kidney lesions generally associated with metals toxicoses in small rodents. Samples were collected at the Pinenut Mine (active mining) and Arizona 1 Mine (post-production) in the Grand Canyon watershed....

We developed multi-scale habitat suitability models for black-tailed prairie dogs (BTPD) in the southwestern Great Plains, corresponding to the western region of the Great Plains LCC. We used long-term (10-yr), high-resolution datasets on BTPD colony boundary locations collected at 7 study areas distributed across the region to develop resource selection functions based on colony locations and expansion patterns. Models are based on (1) soil maps and associated Ecological Sites (NRCS SSURGO database), (2) a topographic wetness index based upon water runoff and solar insolation patterns (TWIsi) that tests a priori hypotheses for topographic controls on BTPD, and (3) broad climatic gradients in temperature and mean...

The black‐tailed prairie dog (Cynomys ludovicianus) is considered an indicator species for the short grass prairie of North America; however, this species currently occupies an estimated 2% of its original distribution. Persistent and pervasive poisoning, and sylvatic plague have fragmented the remaining populations. It is not well understood how these population fragments are connected in a heterogeneous landscape of land use practices and land cover types, but quantifying population isolation and individual measures of dispersal across the landscape are essential to predicting both the vulnerability of extinction due to stochastic processes and the probability of disease emergence. To better understand how land...

We determined temporal and spatial differences in abundance and habitat use by small mammals in southeastern Utah as part of an effort to enhance management of the Mexican Spotted Owl (Strix occidentalis lucida), listed by the federal government as threatened. Woodrats (Neotoma spp.) were captured only in canyons and most frequently in the pinyon-juniper (Pinus edulis-Juniperus osteosperma) vegetation type. White-footed mice (Peromyscus spp.) were found in a variety of vegetation types in both canyons and mesas. The deer mouse (P. maniculatus) was generally the most frequently captured species among vegetation types. We found seasonal and yearly differences in relative abundance of each small mammal species. Our...
Studies were conducted to assess the behavioral responses of silky pocket mice, Perognathus flavus, to test odors associated with two naturally occurring predators (northern grasshopper mouse, Onychomys leucogaster, and Norway rat, Rattus norvegicus), a novel test odor (sugar glider, Petaurus breviceps), and a control odor (water). Pocket mice were tested in a chamber in which they had access to two cages containing food; one of these cages contained no odor (control), while the other contained a predator odor. When both cages contained no test odors, pocket mice showed no preference for one cage over the other; they spent equivalent amounts of time in and in front of each cage, and in the frequency of feeding bouts...
The ecological relationships of three cricetine species-Peromyscus maniculatus, Peromyscus boylii, and Neotoma stephensi-and their utilization of habitat were revealed by species removals from unfenced plots and vegetation tailoring experiments. When N. stephensi, a woodland and shrubland species of woodrat, was removed from a manzanita-oak shrubland and pinyon-juniper woodland, P. boylii showed few significant changes in its use of the vegetational microhabitats on the grid or in the nature of its arboreal activity. However, when P. boylii, a woodland and shrubland mouse, was removed from a grid in juniper-oak shrubland and juniper grassland, both P. maniculatus, an inhabitant of open habitats such as grassland,...
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, the inherent variability of resource availability in deserts, and hence consumer dynamics, can also make them challenging ecosystems to understand. Study of a Chihuahuan desert ecosystem near Portal, Arizona, USA, began in 1977. At this site, 24 experimental plots were established in 1977 and divided among controls and experimental manipulations. Experimental manipulations over the years include removal of all or some rodent species, all or some ants, seed additions, and various alterations of the annual plant community. While some of these manipulations...
