Nongeographic Variation In The Long-Nosed Bat, Choeroniscus Intermedius, Hugh H. Genoways, Robert J. Baker, Bernard Wyatt

University of Nebraska State Museum: Mammalogy Papers

Of the 12 measurements analyzed, only length of tail exhibited enough individual variation to warrant its deletion in analysis of geographic or interspecific variation in the genus Choeroniscus. Also, because of the difficulty in consistently taking the measurement, we also suggest elimination of postorbital constriction.

Specimens of Choeroniscus intermedius were found to exhibit significant secondary sexual variation in five of the 12 measurements studied. Therefore, it is clear that males and females should be separated in analyses of variation within members of the genus. Females were found to be the larger in 10 of the 12 measurements--similar to the …

A Simulation Model Of Peromyscus Leucopus In An Area Of The Great Dismal Swamp, James E. Paschal Jr.

Biological Sciences Theses & Dissertations

A computer simulation model was developed to explain the population dynamics of the white-footed mouse (Peromyscus leucopus) in an area of the Great Dismal Swamp. The model was designed to provide an experimental base for future studies. The model indicates relationships between food availability, home range size, competition with Peromyscus nuttali habitat selection and reproduction.

White-footed mice were trapped in the Old Dismal Town site during each season from April, 1972 through March, 1973. The age-sex structure of the population was determined, and was compared with the simulated structure. Although there were significant discrepancies between the comparisons, the …

Hunting the Ring-necked Pheasant

Season of Testing: Nebraska’s winters test a pheasant’s mettle, but given good cover and an adequate food supply, the ringneck is almost impervious to the elements

Status Of The Mountain Lion In Arkansas, John A. Sealander, Philip S. Gipson

Journal of the Arkansas Academy of Science

Two authenticated kill records of the mountain lion, Felis concolor, in Arkansas are reported as well as numerous reliable sight records spanning an approximately 30-year period. Distribution of sightings in the state is discussed in relation to an expanding deer population. The cougar probably never was exterminated in Arkansas but it still may be considered endangered.

Checklist Of Arkansas Fishes, Thomas M. Buchanan

Journal of the Arkansas Academy of Science

Arkansas has a large, diverse fish fauna consisting of 193 species known to have been collected from the state's waters. The checklist is an up-to-date listing of both native and introduced species, and is intended to correct some of the longstanding and more recent erroneous Arkansas records.
