Recent Observations Of The Distribution Of Woodchucks (Marmota Monax) In Arkansas, C. Renn Tumlison, D. Blake Sasse, Todd Pennington, Nicole Freeman Jan 2007

Recent Observations Of The Distribution Of Woodchucks (Marmota Monax) In Arkansas, C. Renn Tumlison, D. Blake Sasse, Todd Pennington, Nicole Freeman

Journal of the Arkansas Academy of Science

During the last couple of decades, the distribution of the woodchuck (Marmota monax) appeared to be expanding southward in Arkansas (Tumlison et al. 2001). An increase in the frequency of new sightings led us to re-evaluate the present status of this species of squirrel in the state. The woodchuck is not easily confused with other mammals, therefore we sought records of sightings to update information about its distribution. Recent range expansion had been documented in southwestern Arkansas, so we placed notices in stores and advertised in local newspapers in that region to intensively seek new records of sightings from the …


Ants (Hymenoptera: Formicidae) Of Arkansas Post National Memorial, David M. General, Lynne C. Thompson Jan 2007

Ants (Hymenoptera: Formicidae) Of Arkansas Post National Memorial, David M. General, Lynne C. Thompson

Journal of the Arkansas Academy of Science

A combination of techniques was used to collect ants at the Arkansas Post National Memorial, Arkansas County. The techniques were wood breaking, leaf-litter sifting with Berlese extraction, tree baiting, pitfall trapping, and visual searching. Twenty-five genera and 46 species were collected. Three genera are new distributional records for the state: namely, Discothyrea, Proceratium, Protomognathus, and Strumigenys.. Nine species are new state records. Fourteen of the genera and 32 of the species collected are new records for Arkansas County.

Characterization Of Bacteriophages Of Pseudomonas Syringae Pv. Tomato, Sara E. Prior, Amanda J. Andrews, Russell O. Nordeen Jan 2007

Characterization Of Bacteriophages Of Pseudomonas Syringae Pv. Tomato, Sara E. Prior, Amanda J. Andrews, Russell O. Nordeen

Journal of the Arkansas Academy of Science

Bacteriophages from supernatants of the plant pathogenic bacteria Pseudomonas syringae pv. tomato (P. tomato) were isolated, enriched, and purified by density block centrifugation in cesium chloride (CsCl) step gradients. The DNA from purified phage was isolated and digested with the restriction endonucleases EcoRl or HindIII. Three different DNA fingerprint patterns were determined indicating 3 unique phage isolates. Genome sizes of the phage ranged from 40 to 52 kilobases (kB). Buoyant densities of phage particles in CsCI varied from 1.36 to 1.51 glml. Electron microscopy revealed a single morphological type with an elongated polyhedral head and a long tail indicating the …
