Classification And Protection Status Of Remnant Natural Plant Communities In Arkansas, William F. Pell Jan 1981

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 …

Pre-Impoundment Limnological Study Of The Strawberry River In Northeastern Arkansas, Henry W. Robison, George L. Harp Jan 1971

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 Jan 1963

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, …
