Reproduction In The Hispid Cotton Rat, Sigmodon-Hispidus Say And Ord (Rodentia: Muridae), In Southeastern Virginia, Robert K. Rose, Michael H. Mitchell
Biological Sciences Faculty Publications
The hispid cotton rat, Sigmodon hispidus Say and Ord, a species of the southwestern United States that has been moving northward and eastward in this century, was first observed in Virginia in 1940. In this study of the cotton rat in southeastern Virginia, most males were reproductively competent from February through November, embryos were recorded from March through October, and litter sizes were comparable to those from other locations except Kansas. Also unlike the cotton rat in Kansas, animals grew at substantial rates during the winter in Virginia. The hispid cotton rat seems to have adjusted its breeding season in …

Small Mammals In The Great Dismal Swamp Of Virginia And North Carolina, Robert K. Rose, Roger K. Everton, Jean F. Stankavich
Biological Sciences Faculty Publications
Small" mammals were surveyed in a range of habitats in the Great Dismal Swamp of Virginia and North Carolina. The survey is based on three chronologically overlapping studies, each lasting 15-18 months and for which the results have been reported separately. A different trapping method was used in each of the three studies: nest boxes, Fitch live traps, or pitfall traps. Only two species of mammals, both arboreal, were taken in nest boxes, compared with 10 and 9 species in Fitch live traps and pitfall traps, respectively. The Fitch live traps had a much higher catch rate per 1,000 trap-nights …

Freshwater Fishes Of Shipstern Nature Reserve, Caspar F. A. Bijleveld
Freshwater Fishes Of Shipstern Nature Reserve, Caspar F. A. Bijleveld
Physiology Faculty Research Publications
A survey of fishes in and around Shipstern Nature Reserve in Northern Belize, Central America, was carried out over a period of eight months, from February to September 1990. Its purpose was to establish a preliminary list of the fishes of Shipstern Nature Reserve, including descriptions, distribution and collecting data and additionally to describe some of the habitats in which the fishes were found. This study focuses on fishes considered to be freshwater species. These occurred for the greater part in brackish habitats. Nevertheless, a few fish considered as marine species were caught in the waters of the reserve and …
Helminth Parasitism In Martens (Martes Americana) And Ermines (Mustela Erminea) From Washington, With Comments On The Distribution Of Trichinella Spiralis, Eric P. Hoberg, Keith B. Aubry, J. David Brittell
Helminth Parasitism In Martens (Martes Americana) And Ermines (Mustela Erminea) From Washington, With Comments On The Distribution Of Trichinella Spiralis, Eric P. Hoberg, Keith B. Aubry, J. David Brittell
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Helminths are reported for the first time from ermines (Mustela erminea) and martens (Martes americana) in Washington, USA. Among 22 adult ermines, 41% were infected by one or more of five species (Taenia mustelae, Alaria mustelae, Molineus patens, M. mustelae, and Trichinella spiralis). Among 78 adult martens from three geographic localities, the prevalence was 83%. Nine species were identified (Mesocestoides sp., T. mustelae and T. martis americana, Euryhelmis squamula, M. patens, Baylisascaris devosi, Physaloptera sp., Soboliphyme baturini, and T. spiralis). Trichinella spiralis …

Hawks, Eagles, And Falcons Of North America: Biology And Natural History, Paul A. Johnsgard
Paul Johnsgard Collection
I have tried to present an adequate if far from exhaustive survey of the general biology, ecology, and behavior of all the included species, written so as to be understandable to the interested layman as well as useful to the biologist who might be looking for relevant literature citations or trying to deal with a specific question without resorting to extensive library searches. The larger number of species of North American hawklike birds (31, compared to 19 owl species) has required that I keep the individual species accounts substantially shorter. I have excluded the New World vultures from consideration, primarily …

Wolf Population Survival In An Area Of High Road Density, L. David Mech
Wolf Population Survival In An Area Of High Road Density, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Wolf mortality in a high-road-density area of Minnesota exceeds that in an adjacent wilderness, and is primarily human-caused. The wolf population there is maintained primarily by ingress from the adjacent wilderness areas. A road density of 0.58 km/km2 can be exceeded and the area still support wolves if it is adjacent to extensive roadless areas.

Leaf Optical And Indirect Lai Measurements In Wheat And Alfalfa At Maciv: Agmet Progress Report 89-4, E. A. Walter-Shea, B. L. Blad
School of Natural Resources: Documents and Reviews
Interpretation of remotely sensed vegetative surfaces requires an understanding of the interaction of radiation with the various components of vegetation. Leaves are the most important component. Thus it is important to know the optical properties of individual leaves as well as the amount and distribution of leaves making up the vegetative cover. The objectives of our study were 1) to characterize the reflectance from and transmittance through adaxial and abaxial surfaces of individual wheat and alfalfa leaves and 2) to compare the traditional, time-consuming, destructive method of estimating LAI (direct method) to a relatively quick, indirect estimate of LAI in …

The Status Of Erythronium Albidum And E. Mesochoreum (Liliaceae) In Nebraska, Robert B. Kaul
The Status Of Erythronium Albidum And E. Mesochoreum (Liliaceae) In Nebraska, Robert B. Kaul
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Two species of Erythronium grow in the eastern quarter of Nebraska, but there are none elsewhere in the State. Erythronium albidum is locally abundant, mostly in upland bur oak forests, and has been collected in 18 counties since 1864. Erythronium mesochoreum is becoming rare because its habitat--virgin tall-grass prairie--is disappearing. It is known to grow now in six east-central counties, but it probably could be found in some remnant prairies in all counties south and east of the Platte and Big Blue rivers, respectively. Distributional data about these species is herein brought up to date relative to earlier published reports. …
Caribbean Island Zoogeography: A New Approach Using Mitochondrial Dna To Study Neotropical Bats, Carleton J. Phillips, Dorothy E. Pumo, Hugh H. Genoways, Phillip E. Ray
Caribbean Island Zoogeography: A New Approach Using Mitochondrial Dna To Study Neotropical Bats, Carleton J. Phillips, Dorothy E. Pumo, Hugh H. Genoways, Phillip E. Ray
University of Nebraska State Museum: Mammalogy Papers
Genetic analysis of animal mitochondrial DNA is a new and valuable addition to the battery of techniques available to zoogeographers. This paper describes characteristics of mitochondrial DNA (mtDNA) that make it applicable for the study of island zoogeography.
Some traditional zoogeographic questions are examined using mtDNA from the Neotropical fruit bat, Artibeus jamaicensis. The specific questions are: 1) To what extent are island populations isolated (that is, does interbreeding occur between the insular subspecies)? 2) Can a single founding female account for the mitochondrial genomes on specific islands in the Antilles? 3) Is there a correlation between the genomic …
The Bats Of Fountain Cavern, Hugh H. Genoways
The Bats Of Fountain Cavern, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
First paragraph:
During May 1988, two species of bats--Brachyphylla cavernarum (Antillean cave bat) and Natalus stramineus (funnel-eared bat)--were captured at the opening of Fountain Cavern. Only Brachyphylla cavernarum was captured inside of the cave. The weather was extremely wet during our visit to Anguilla so our work in Fountain Cavern was limited by hazardous conditions. Nevertheless, we did make a thorough survey of the bats inside the cave. There is only one other species on Anguilla--Monophyllus redmani (Antillean long-tongued bat)--that might be expected to utilize Fountain Cavern as a roosting site.
Includes the author's recommendations about conservation for …
