Analysis Of The Fall And Winter Diet Of The Bobcat In Eastern Arkansas, C. Renn Tumlison, V. Rick Mcdaniel
Analysis Of The Fall And Winter Diet Of The Bobcat In Eastern Arkansas, C. Renn Tumlison, V. Rick Mcdaniel
Journal of the Arkansas Academy of Science
Food habits of the bobcat (Felis rufus) in eastern Arkansas were examined based on stomach contents of 148 specimens. Rabbits (Sylvilagus floridanus and S. aquaticus) were the primary food source for males, females, and kittens. Rice rats (Oryzomys palustris), nutria (Myocastor coypus), and several species of waterfowl are first reported as food of bobcats in Arkansas. Cotton rats (Sigmodon hispidus) and muskrats (Ondatra zibethica) were more common in bobcat diets in eastern versus western Arkansas. Adult males did not use smaller prey but this food source was common, in kittens; females were intermediate in their use of smaller prey.

Bats Of The Ouachita Mountains, David A. Saugey, Darrell R. Heath, Gary A. Heidt
Journal of the Arkansas Academy of Science
A survey was conducted from June, 1982 through January, 1989 to determine the occurrence of bat species in the Ouachita Mountain region of west-central Arkansas and southeastern Oklahoma, with emphasis on censusing lands managed by the USDA Forest Service, Ouachita National Forest. Seven genera and 13 species of bats in the families Vespertilionidae and Molossidae were captured. Species represented included: Eptesicus fuscus, Lasionycteris noctivagans, Lasiurus borealis, Lasiurus cinereus, Lasiurus seminolus, Myotis austroriparius, Myotis keenii, Myotis leibii, Myotis lucifugus, Myotissodalis, Nycticeius humeralis, Pipistrellus subflavus, and Tadarida brasiliensis cynocephala.
Blackland Prairies Of Southwestern Arkansas, Thomas L. Foti
Blackland Prairies Of Southwestern Arkansas, Thomas L. Foti
Journal of the Arkansas Academy of Science
The Blackland Prairie community type has been described in Texas; related communities exist in Alabama and Mississippi. The Arkansas variant of the community has not been described in detail. Since the Arkansas Natural Heritage Commission began a systematic inventory of the community in 1985, more than 36 remnants have been identified that retain substantial natural character. However, all show some degree of disturbance. Based on aerial photo interpretation, aerial inspection, and ground study, an initial description of the community is presented, including original distribution, soil, vegetation and relationship to similar communities of Texas, Mississippi, and Alabama.

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.

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

Comparison Of The Symbiotic Fauna Of The Family Plethodontidae In The Ouachita Mountains Of Western Arkansas, Douglas A. Winter, Wojciech M. Zawada, Arthur A. Johnson
Journal of the Arkansas Academy of Science
During the spring of 1985, 101 salamanders representing six host species (29 Plethodon ouachitae, 25 P. caddoensis, 6 P. fourchensis, 23 P. serratus, 13 Desmognathus brimleyorum, and 5 P. glutinosus glutinosus) were collected from six localities in three counties in Arkansas (Polk, Scott, and Montgomery) and examined for symbionts. With the exception of Hannemania dunni, all symbionts recovered from the first five species listed constitute new host records, and the endoparasitic fauna in all species establish new locality records. Examinations revealed one or more species of parasites in 82% of the hosts. Eight species of symbionts (3 nematode, 1 trematode, …

Application Of A New Method For Quantitative Evaluation Of Stream Benthic Algal Populations, Richard L. Meyer, Neil Woomer
Application Of A New Method For Quantitative Evaluation Of Stream Benthic Algal Populations, Richard L. Meyer, Neil Woomer
Arkansas Water Resources Center Technical Reports
The response of stream biota to changing water quality or other ecosystem perturbations is an important means of assessing water quality. The dynamic nature of streams induces significant sampling and measurement problems. In smaller streams a true algal plankton subcommunity is lacking and the major location for the production of algae is attachment onto stones and other stable surfaces at the substrate-water interface. Several artificial techniques have been developed to analyze the composition of a portion of the epiphytic periphyton (algae attached to stones) but not populations which are qualitatively and quantitatively similar to natural substrates. A newly developed substrate …
Seasonal Abundance, Movement And Diversity Of Fishes In An Ozark Stream, Michael R. Dewey
Seasonal Abundance, Movement And Diversity Of Fishes In An Ozark Stream, Michael R. Dewey
Journal of the Arkansas Academy of Science
Seasonal fluctuations in fish abundance in Mud Creek occurred throughout the year at all sampling stations. At the two upper stations abundance was high and unstable during winter and early spring and decreased after heavy rainfall in mid-April. Abundance was low throughout the summer months, increasing in the fall due to large numbers of young-of-the-year. However, a different seasonal cycle occurred at the lower station which included deeper pools. Numbers were low and stable throughout the winter and early spring but high and unstable during the summer. Bigeye shiners (Notropis boops) and bluntnose minnows (Pimephales notatus) were the most mobile …
Classification And Protection Status Of Remnant Natural Plant Communities In Arkansas, William F. Pell
Classification And Protection Status Of Remnant Natural Plant Communities In Arkansas, William F. Pell
Journal of the Arkansas Academy of Science
A classification and inventory of Arkansas's remaining tracts of relatively undisturbed vegetation was initiated in 1979. Based on extensive literature surveys and field work, the classification includes five physiognomic classes, 17 cover classes, and 46 cover types, arranged hierarchically. High quality examples of ten of the cover types have been located in designated wilderness or state natural areas, where they are protected by law, while an additional three occur in research natural areas or Forest Service special interest areas. The remaining 33 cover types have no known long-term protection. Lands having wilderness, state natural area, research natural area, or special …
Environmental Evaluation Report On The Big Mulberry Creek Basin In Franklin, Madison, Newton, Johnson And Crawford Counties, Arkansas, Edward E. Dale Jr.
Environmental Evaluation Report On The Big Mulberry Creek Basin In Franklin, Madison, Newton, Johnson And Crawford Counties, Arkansas, Edward E. Dale Jr.
Arkansas Water Resources Center Technical Reports
The environmental evaluation report which follows is based on information supplied by the Corps of Engineers, Little Rock District, available literature, field observations made during the summer of 1972, and results of research now in progress on natural features of the Big Mulberry Basin. Since most major dams, levees, and flood retarding structures now in existence in the Ozarks have been constructed since about 1940, opportunities to make long term studies of their effects have been limited. Also, the natural vegetation, fauna, and archeology of the Big Mulberry Basin have not been extensively investigated, but available sources provide enough information …

Pre-Impoundment Limnological Study Of The Strawberry River In Northeastern Arkansas, Henry W. Robison, George L. Harp
Pre-Impoundment Limnological Study Of The Strawberry River In Northeastern Arkansas, Henry W. Robison, George L. Harp
Journal of the Arkansas Academy of Science
A study of pre-impoundment limnological characteristics of the Strawberry River was made from August, 1967 to June, 1968. Two collecting stations were established, one upstream which would not be inundated and a lower station which would be inundated when impoundment was complete. The Strawberry River was characterized by high alkalinity and pH, low carbon dioxide and turbidity, and adequate oxygen values. Plankton was characterized by limited numbers of Staurastrum, Gomphonema, and Rotatoria. Pool-riffle communities were ill-defined. Chironomidae, Oligochaeta and Ephemeroptera were dominant pool macroinvertebrates among 13 taxa collected. Of the 20 taxa collected in riffles Trichoptera, Ephemeroptera, Simuliidae and Chironomidae …

Comparison Of Spider Populations Of Ground Stratum In Arkansas Pasture And Adjacent Cultivated Field, W. H. Whitcomb, Harriet Exline, Maxine Hite
Journal of the Arkansas Academy of Science
Of 64 species of spiders taken from the ground stratum of an Arkansas pasture and adjoining cotton field, only 26 were common to both. Twenty-two were collected only in the cotton field; 16, only in the pasture. Many of the 18 species of lycosids were taken in greater numbers in the cultivated field, especially Pardosa milvina and Lycosa helluo. Eight species of lycosids were found only in the cotton field; two, only in the pasture. Only Schizocosa avida, of the better represented lycosids, appeared to show no preference. Similar relationships are given for dictynids, erigonids, linyphiids, oxyopids, gnaphosids, clubionids, thomisids, …
