Of these records, four constitute range extensions for the documented distributions of these species in Oklahoma (Scalopus aquaticus, Microtus pinetorum, Neotoma floridana, Reithrodontomys fulvescens) and one is a range extension for North America (Baiomys taylori). Specimens were collected as part of a survey of 14 western Oklahoma Wildlife Management Areas. These records enhance our understanding of the distribution and natural history of mammalian fauna on the southern Great Plains.
Modern extirpation of the Texas kangaroo rat, Dipodomys elator, in Oklahoma: changing land use and climate over a century of time as the road to eventual extinction

The project encompassed 15 surveys on 93 nights; 266 localities were surveyed for a total of 9,094 trap nights and more than 32,428 km of paved and unpaved roads were surveyed for potential habitat and activity. No Texas kangaroo rats were captured or observed. However, 2,178 individuals of 17 mammal species were captured and individuals of 12 additional mammal species were collected and/or observed. New locality and natural history information for mammal species was obtained and six county records were recorded based on specimens and/or observations. Project results and historical information suggest that the Texas kangaroo rat (D. elator) is likely extirpated from the state of Oklahoma.

Anthropogenic effects have led to a network of roads resulting in the dissection of native habitat types. A Geographic Information Systems (GIS) analysis was conducted to evaluate changes in patch number, mean patch size, maximum patch size, and total patch perimeter for each native habitat type occurring in Cimarron County. Results indicated significant habitat fragmentation in the most widespread native habitat type (grama-buffalograss prairie) and moderate to insignificant fragmentation in the other four native habitat types. © 2008 Oklahoma Academy of Science.

Mammal collections of the Western Hemisphere: a survey and directory of collections

The SCC surveyed 429 collections and compiled a directory of 395 active collections containing 5,275,155 catalogued specimens. Over the past decade, 43 collections have been lost or transferred and 38 new or unsurveyed collections were added. Growth in number of total specimens, expansion of genomic resource collections, and substantial gains in digitization and web accessibility were documented, as well as slight shifts in proportional representation of taxonomic groups owing to increasingly balanced geographic representation of collections relative to previous surveys. While we find the overall health of Western Hemisphere collections to be adequate in some areas, gaps in spatial and temporal coverage and clear threats to long-term growth and vitality of these resources have also been identified. Major expansion of the collective mammal collection resource along with a recommitment to appropriate levels of funding will be required to meet the challenges ahead for mammalogists and other users, and to ensure samples are broad and varied enough that unanticipated future needs can be powerfully addressed.
