Small Mammals In The Great Dismal Swamp Of Virginia And North Carolina, Robert K. Rose, Roger K. Everton, Jean F. Stankavich
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 …
Reproduction In The Hispid Cotton Rat, Sigmodon-Hispidus Say And Ord (Rodentia: Muridae), In Southeastern Virginia, Robert K. Rose, Michael H. Mitchell
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 …
Characterization And Expression Of The Cbbe' Gene Of Coxiella Burnetii, Michael F. Minnick, Robert A. Heinzin, Marvin Eugene Frazier, Louis P. Mallavia
Characterization And Expression Of The Cbbe' Gene Of Coxiella Burnetii, Michael F. Minnick, Robert A. Heinzin, Marvin Eugene Frazier, Louis P. Mallavia
Biological Sciences Faculty Publications
A gene which is unique to the QpRS plasmid from chronic isolates of Coxiella burnetii was cloned, sequenced, and expressed in Escherichia coli. This gene, termed cbbE', codes for a putative surface protein of approximately 55 kDa, termed the E' protein. The cbbE' gene is 1485 bp in length, and is preceded by predicted promoter regulatory sequences of TTTAAT (-35), TATAAT (-10), and a Shine-Dalgarno sequence of GGAGAGA, all of which closely resemble those of E. coli and other rickettsiae. The open reading frame (ORF) of cbbE' ends with a UAA codon followed by a second in-frame UAG stop codon …

Heat Dissipation, Gas Exchange And Acid-Basic Balance In The Land Snail Oreohelix During Short-Term Estivation, Bernard Rees
Heat Dissipation, Gas Exchange And Acid-Basic Balance In The Land Snail Oreohelix During Short-Term Estivation, Bernard Rees
Biological Sciences Faculty Publications
Within 4 days following entry into estivation, heat dissipation and oxygen consumption by the land snail Oreohelix spp. decreased by 83 % compared to standard non-estivating rates. During both non-estivating and estivating conditions, the quantity of heat dissipated per mole of O2 consumed was indicative of a completely aerobic metabolism. This calorimetric-respirometric (C/R) ratio was — 461 ± 12 kJ moP102 (S.E.M., N=5) under standard non-estivating conditions and — 464±26kJmol~1O2 (7V=4) during estivation. Respiratory exchange ratios reflected a primary dependence upon carbohydrate as a metabolic substrate during both states. Carbon dioxide retention occurred during the first 36h of estivation, resulting …
Migration Routes Of New World Sanderlings (Calidris Alba), J. P. Meyers, M. Sallaberry A., E. Ortiz, G. Castro, L. J. Gordon, John L. Maron, C. T. Schick, E. Tablio, P. Antas, T. Below

We color-marked Sanderlings (Calidris alba Pallas) at 19 locations in 6 countries in the New World and coordinated a network of volunteers to locate banded individuals in migration over a five-year period. The observers reported 252 independent sightings of birds in countries different from the country of banding. Sanderlings that migrate north to the Arctic from Chile and Peru travel principally through the central corridor (Texas and northward) of the United States and Canada; smaller numbers follow the Pacific coast. A few migrate north from the Pacific coast of South America along the Atlantic coast of the United …
