Comments On Estimating Population Rate Of Increase From Age Frequency Data, C. Renn Tumlison, V. Rick Mcdaniel Jan 1988

Comments On Estimating Population Rate Of Increase From Age Frequency Data, C. Renn Tumlison, V. Rick Mcdaniel

Journal of the Arkansas Academy of Science

Although many papers have described assumptions and calculations of r from different kinds of data, none has compared estimates of r for the same real data set under different assumptions. We used the age distributions of gray foxes collected during six trapping seasons to estimate and compare r and lₓ series derived under different assumptions. Because trapped foxes are killed, they are believed by some to represent death history data. We found this treatment underestimates mortality so overestimates survivorship and leads to erroneous conclusions about the population. Use of a projection matrix allowed prediction of population size and thus allowed …

Mandibular Dentition In Six Species Of Salamanders, Genus Plethodon (Caudata: Plethontidae), From Arkansas Using Scanning Electron Microscopy, Richard A. Atwill, Stanley E. Trauth Jan 1988

Mandibular Dentition In Six Species Of Salamanders, Genus Plethodon (Caudata: Plethontidae), From Arkansas Using Scanning Electron Microscopy, Richard A. Atwill, Stanley E. Trauth

Journal of the Arkansas Academy of Science

The mandibular (dentary) dentition of six species of Plethodon (P. caddoensis, P. dorsalis, P. fourchensis, P. glutinosus, P. ouachitae, and P. serratus) from Arkansas was studied using scanning electron microscopy. In all species, the mandibular teeth were bicuspid, and each tooth possessed a prominent labial cusp and a well-developed, inward-curving lingual cusp. All species showed similar tooth crown features, except P. caddoensis which exhibited a reduced tooth height and a reduced lingual cusp (only slightly larger than the labial cusp). We compared our data with other studies on premaxillary, maxillary, and palatal teeth in Plethodon and found overall similarities in …

Toe Tip Morphology In Six Species Of Salamanders, Genus Ambystoma (Caudata: Ambystomatidae) From Arkansas Using Scanning Electron Microscopy, Stanley E. Trauth, J. D. Wilhide Jan 1988

Toe Tip Morphology In Six Species Of Salamanders, Genus Ambystoma (Caudata: Ambystomatidae) From Arkansas Using Scanning Electron Microscopy, Stanley E. Trauth, J. D. Wilhide

Journal of the Arkansas Academy of Science

The toe tip friction surface in six species of Ambystoma (A. annulatum, A.maculatum, A.opacum, A. talpoideum, A. texanum, and A. tigrinum) from Arkansas was examined using scanning electron microscopy. We found no sexual dimorphism in cell surface ultrastructure. Variation within and between species was considerable. The most active burrower, A. tigrinum, possessed the most disorganized cell surface, whereas the least active burrowers (A.annulatum, A.maculatum, and A. opacum) had morphologically similar and relatively smooth toe tips. In A. talpoideum and A. texanum, cell surfaces exhibited microprojections. Only these two species possessed mucous pores in close proximity to the friction surface. The …

Sex Ratios In Bobcat Populations, C. Renn Tumlison, V. Rick Mcdaniel Jan 1988

Sex Ratios In Bobcat Populations, C. Renn Tumlison, V. Rick Mcdaniel

Journal of the Arkansas Academy of Science

Reported sex ratios in bobcat populations have suggested great variation ranging from strong male bias to strong female bias. Explanations offered for these observations have included factors of mobility, activity, behavior, inaccurate data collection, hunting pressure, and population density. Ratios are probably most representative during the winter, when females are no longer under constraints of parental care. Sex determination should be made by experienced observers and preferably through internal examination. The most productive direction for interpretation of validated ratios appears to be in terms of population density, hunting pressure, and the timing of harvest.

Eggtooth Development And Morphology In The Six-Lined Racerunner Cnemidophorus Sexlineatus (Sauria: Teiidiae) Using Scanning Electron Microscopy, Stanley E. Trauth Jan 1988

Eggtooth Development And Morphology In The Six-Lined Racerunner Cnemidophorus Sexlineatus (Sauria: Teiidiae) Using Scanning Electron Microscopy, Stanley E. Trauth

Journal of the Arkansas Academy of Science

Eggtooth development and morphology in the six-lined racerunner, Cnemidophorus sexlineatus, were examined using scanning electron microscopy. The anlage of the embryonic eggtooth emerges from the anterior surface of the palate relatively late during embryonic development. The eggtooth proper erupts through an epithelial sheath and grows anteriorly to project beyond the rostral scale. The mature eggtooth is hollow, has a wall made of enamel and dentine, possesses a sharply-curved body and has a flattened, pointed tip. The eggtooth is shed within several days after the young hatch.

Forest Habitat Use By White-Tailed Deer In The Arkansas Coastal Plain, T. B. Wigley Jr., M. E. Garner Jan 1988

Forest Habitat Use By White-Tailed Deer In The Arkansas Coastal Plain, T. B. Wigley Jr., M. E. Garner

Journal of the Arkansas Academy of Science

Forest habitat use by five radio-equipped white-tailed deer (Odocoileus virginianus) was monitored in the Arkansas Coastal Plain during 1982-84. The deer were located 821 times. Use of forest types was compared to expected use as calculated from availability. The study area was also divided into 491 two-hectare cells for which timber characteristics and number of deer locations were determined. Pine sawtimber was the most heavily used forest type in all seasons and was used more often than expected during spring. Also used more than expected were brushy areas (clearcut but not site prepared) during spring, summer and fall and openings …

Cartographic Trend Analysis Of Furbearer Harvest Distributions In Arkansas, C. Renn Tumlison, Mark Trail, V. Rick Mcdaniel Jan 1987

Cartographic Trend Analysis Of Furbearer Harvest Distributions In Arkansas, C. Renn Tumlison, Mark Trail, V. Rick Mcdaniel

Journal of the Arkansas Academy of Science

Average by-county fur harvest for the last nine harvest seasons (1977-1985) was used as data points to be interpolated using nearest neighbor algorithms in computer-assisted trend analyses. COMPLOT maps were produced which represented a surface of harvest densities drawn over a map of Arkansas. Twelve furbearer species are examined, and "topographic" features of harvest density for each are interpreted in terms of ecology and/or buyer distribution. The trend surface technique removed some of the error inherent to harvest records, and produced an aesthetic graphical display of the information that was more easily interpreted and explained than other methods of analysis …

Fur Trade Records From Arkansas Factory, Arkansas Post, Louisiana Territory, 1805-1810, Paul J. Polechla Jr. Jan 1987

Fur Trade Records From Arkansas Factory, Arkansas Post, Louisiana Territory, 1805-1810, Paul J. Polechla Jr.

Journal of the Arkansas Academy of Science

The United States government established a trading house at Arkansas Post in 1805 on the north bank of the Arkansas River in the newly purchased Louisiana Territory. The goal of this trading house was to foster good relations with the Quapaw tribe and other indigenous peoples. John B. Treat and his successors operated the post and meticulously recorded the number, value, and species of pelts traded. Tabulation of these records, which have been preserved in the National Archives, revealed that 9 or 10 species contributed a total of about 44,000 hides, worth approximately $18,000. White-tailed deer (Odocoileus virginianus) pelts comprised …

Age And Growth Of Redear Sunfish Lepomis Microlophus (Gunthur), From Bob Kidd Lake, Rex R. Roberg, Thoniot T. Prabhakaran, Raj V. Kilambi

Journal of the Arkansas Academy of Science

Total lengths (62-285mm) and body scales from 75 redear sunfish collected by electroshocking from Bob Kidd Lake during October and November 1985 were used for this study. The length-frequency distribution yielded five age groups, however, the body scale analysis revealed eight age groups. The total length scale radius relationship was estimated as, TL = 17.98 + 0.92 Sr . Lengths attained at earlier ages were estimated by the Fraser-Lee method and the Bertlanffy growth model was fitted to the lengths for ages five through ten, and the resulting equation, L₁ = 295 [1 - exp — 0.29 (t - 1.83)], …

Harvest Trends Of The Bobcat (Felix Rufus) In Arkansas, C. Renn Tumlison, V. Rick Mcdaniel Jan 1986

Harvest Trends Of The Bobcat (Felix Rufus) In Arkansas, C. Renn Tumlison, V. Rick Mcdaniel

Journal of the Arkansas Academy of Science

Arkansas bobcat fur harvest records were examined in relation to forest cover, furbuyer distribution, and price. Availability of forest cover correlated with areas of greatest harvest, and a dynamic forest products industry in southern Arkansas is believed to support a greater density, and therefore greater harvest, of bobcats. Comparison of furbuyer distribution with harvest level among physiographic regions suggested that the fur industry in southern Arkansas could expand. Prices increased dramatically in the 1970's, and 94.5% of the variation in harvest level could be explained by price.

Effects Of Low Ph On Lactate Dehydrogenase Kinetics Of Diving And Nondiving Reptiles, Dennis A. Baeyens, Salim R. Hurley Jan 1986

Effects Of Low Ph On Lactate Dehydrogenase Kinetics Of Diving And Nondiving Reptiles, Dennis A. Baeyens, Salim R. Hurley

Journal of the Arkansas Academy of Science

The properties of lactate dehydrogenase were examined in two snake species, Nerodia rhombifera and Elaphe obsoleta, and a turtle species, Pseudemys scripta. Our purpose was to compare the LDH activity of reptiles with limited anaerobic capabilities with that of the well established diver Pseudemys. The Michaelis-Menten kinetics of LDH and its susceptibility to inhibition by elevated pyruvate concentrations were investigated in the brain and heart of the three species. All tissue incubations and enzyme activity determinations were done at a pH of 7.0 in order to stimulate a diving blood pH in the three species. In both tissues the LDH …

Tagging And Marking Crawfish (Procambarus Clarkii) In A Population Estimation Study, Frank Meriweather Jan 1986

Tagging And Marking Crawfish (Procambarus Clarkii) In A Population Estimation Study, Frank Meriweather

Journal of the Arkansas Academy of Science

Crawfish (Procambarus clarkii) were tagged with enumerated plastic streamers and released in 0.1-ha ponds to observe recapture frequency in stand-up traps. Also, crawfish were marked by a uropod punch, released and recaptured in 0.1-ha ponds for population estimation. Survival of streamer-tagged crawfish in indoor tanks averaged 46.7% after 25 days, indicating that tagging caused stress leading to mortality, especially during molt. Recapture frequencies of tagged crawfish indicated sampling bias which obviated use of the tagging method in population assessments. Short term (3-day) survival of marked crawfish (92%) and retention of the mark after molt indicated potential application in population assessment …
