Autumn Foods Of White-Tailed Deer In Arkansas, Thomas A. Nelson, Luke Eggering, Danny Adams
Autumn Foods Of White-Tailed Deer In Arkansas, Thomas A. Nelson, Luke Eggering, Danny Adams
Journal of the Arkansas Academy of Science
Rumen contents from 65 hunter-harvested deer were collected and analyzed during 1985-86 to estimate the principal autumn foods consumed by white-tailed deer inhabiting the Ozark Mountains, Arkansas River Valley, and Gulf Coastal Plain regions of Arkansas. Deer in the Ozarks and Coastal Plain fed heavily on woody browse species, which comprised 99% of rumina identified from these 2 regions. Acorns were the primary food of deer in these heavily forested areas. Acorns and other woody browse were less important to deer inhabiting the Arkansas River Valley. In this region of interspersed agricultural fields and bottomland forests, soybeans and corn comprised …
Comments On Estimating Population Rate Of Increase From Age Frequency Data, C. Renn Tumlison, V. Rick Mcdaniel
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 …

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

Factors Affecting Annual Deer Harvest In Arkansas, Richard A. Kluender, T. Bentley Wigley Jr., Michael E. Cartwright
Factors Affecting Annual Deer Harvest In Arkansas, Richard A. Kluender, T. Bentley Wigley Jr., Michael E. Cartwright
Journal of the Arkansas Academy of Science
An understanding of general forces affecting annual harvest is essential to the management of white-tailed deer (Odocoileus virginianus). A predictive model based on such factors would be valuable to managers. The relationship between 27 different variables and annual, legal deer harvest in Arkansas was evaluated for 1957-1986. Variables most affecting harvest were soybean acreage, hay acreage, number of days in the deer season, rain during the deer season, and total state timber production, total state pulpwood production, and deer harvest 2 years prior. Because significant autocorrelation and heteroscedasticity were present in the variables, log-linear, first differencing and non-linear quasi-Newton regression …
Sex Ratios In Bobcat Populations, C. Renn Tumlison, V. Rick Mcdaniel
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.
