In order to determine the prevalence and distribution of the human pathogen, Escherichia coli O157:H7, in free-ranging deer, hunters were asked to collect and submit fecal samples from deer harvested during a regular firearm season (14-22 November 1998). Prior to the season, 47% of the hunters with permits in the southeastern Nebraska (USA) study area(More)
This study was designed to determine the significance of a single intronic base change (IVS5-12 G-->A) found in a family with a history of breast cancer. This change is predicted to form a cryptic splice site resulting in the addition of 11 nucleotides to the BRCA1 transcript. The BRCA1 gene of the relatives and control individuals was sequenced and(More)
Tens of thousands of children deliver before they are full term each year. Although many social, environmental, and medical risk factors have been suggested, the etiology of a large percentage of preterm labor cases is still unknown. It has been noted for many years that preterm delivery is a condition that runs in families. Evidence concerning its(More)
Populations of pronghorn (Antilocapra americana) are subjected to multiple forms of density-dependent and density-independent regulation. Little is known about the combined effects of these variables across multiple populations throughout the landscape. The objectives of this study were to examine long-term trends in density and recruitment in pronghorn and(More)
In 2007, two new populations of feral swine were discovered in Nance and Valley counties, Nebraska, USA. Necropsies and serologic testing was done on two individuals from the Nance County herd. Results indicated that a lactating sow had positive antibodies for pseudorabies virus (PRV). Investigations conducted by Nebraska Game and Parks Commission Law(More)

Dispersal is a basic feature ofthe natural history of moose. Most infomiation about moose dispersal pertains to short-distance movements because long-distance movements are uncommon and difficult to observe. Since the 1950s, moose populations have been increasing in Minnesota and North Dakota. This may have contributed to several long-distance dispersal(More)
—Two subspecies of the big brown bat (Eptesicus fuscus) are reported to occur in Nebraska. The eastern race, E. f. fuscus, is reportedly bigger and darker than its western counterpart E. f. pallidus. Where these 2 subspecies come in contact is the subject of debate. We used external, cranial, and colorimetric data to investigate geographic variation among(More)
