Pentatomidae Of Arkansas, Harvey E. Barton, Linda A. Lee
Pentatomidae Of Arkansas, Harvey E. Barton, Linda A. Lee
Journal of the Arkansas Academy of Science
A total of 30 genera and 53 species and subspecies of Pentatomidae are reported as occurring or possibly occurring in Arkansas. Fifty species and subspecies contained in 29 genera were collected or recorded from previously collected material. Based on distributional records in the literature, three additional species and one genus are listed as probably occurring in Arkansas. County and seasonal records are reported for each taxon.
Microhabitat Distribution And Its Effect Of Prey Utilization In Sympatric Populations Of Plethodon Glutinosus And Plethodon Dorsalis In Northwestern Arkansas, James M. Britton
Microhabitat Distribution And Its Effect Of Prey Utilization In Sympatric Populations Of Plethodon Glutinosus And Plethodon Dorsalis In Northwestern Arkansas, James M. Britton
Journal of the Arkansas Academy of Science
A study was done on sympatric populations of Plethodon glutinosus and P. dorsalis in northwestern Arkansas to determine the relative distribution of the two species and the relationship between their distribution and the utilization of available prey. Upon capture, total length, location, and habitat type were recorded for each salamander. Stomach content samples were obtained by forced regurgitation, and the animals were released. Samples of the local litter fauna were taken to determine prey availability. Habitat data were obtained for 171 salamanders; 76 P. glutinosus and 95 P. dorsalis. Stomach content samples were taken from 67 salamanders; 32 P. glutinosus …
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 …
Preliminary Report On The Fishes Of The Upper Saline River, Polk And Howard Counties, Arkansas, And Observations On Their Relationships With Land Use And Physiochemical Conditions, Stephen A. Sewell
Journal of the Arkansas Academy of Science
The Saline River of southwest Arkansas was impounded by Dierks Lake in 1975. Intensive collecting efforts were made in the river system above Dierks Lake during March, April, and May 1980. Collected specimens were compared with ichthyofaunal lists prior to impoundment. Historic occurrants which were not collected include Notropis amnis, Notropis ortenburgeri, Moxostoma duquesnei, Ammocrypta vivax, and Percina copelandi. Additions to the ichthyofaunal list for the drainage include Fundulus notatus, Etheostoma spectabile, and Percina caprodes. The evidence indicates that 33 species representing six families inhabit the system from the headwaters in Polk County, Arkansas, to Dierks Lake, Howard County, Arkansas. …

Flying Insect Populations As Sampled By Malaise Trap On Crowley's Ridge In Northeast Arkansas, Lynita M. Cooksey, Harvey E. Barton
Flying Insect Populations As Sampled By Malaise Trap On Crowley's Ridge In Northeast Arkansas, Lynita M. Cooksey, Harvey E. Barton
Journal of the Arkansas Academy of Science
Malaise trap collections from woodlot and open field sampling sites on Crowley's Ridge yielded 10,830 individuals during the months of May, July and September, 1980. Greatest numbers of insects were collected in May, with fewest in September. Four orders comprised 97% of the total catch: Diptera (57%), Lepidoptera (17%), Hymenoptera (15%) and Homoptera (8%). Coleoptera, Hemiptera, Neuroptera, Odonata and Orthoptera comprised the remaining 3%. Ordinal composition and seasonal occurrence patterns are discussed and compared for the two sampling sites.
