Aquatic Macroinvertebrates Of Three Acid Bogs On Crowley's Ridge In Northeast Arkansas, Jerry L. Farris, George L. Harp
Aquatic Macroinvertebrates Of Three Acid Bogs On Crowley's Ridge In Northeast Arkansas, Jerry L. Farris, George L. Harp
Journal of the Arkansas Academy of Science
Qualities and quantities of parameters composing the bog systems in Northeast Arkansas are not entirely reflective of those defining bogs of the northern United States. While pH is restricting to the organisms of each bog studied (4.8-6.9), the major limiting factor is the amount of available water. Three acidophilic bogs with shallow water depths (2-30 cm) yielded a total of 75 aquatic macroinvertebrate taxa. The bog with greatest surface area supported 67 taxa and a mean numerical standing crop of 14 organisms/2 hr sampling period. The bog with the smallest surface area had 13 taxa and a mean standing crop …
Leaf Processing In A Slough Of An Ozark Stream, Don F. Petty, Arthur V. Brown
Leaf Processing In A Slough Of An Ozark Stream, Don F. Petty, Arthur V. Brown
Journal of the Arkansas Academy of Science
Processing of sugar maple (Acer saccharum), black oak (Quercus velutina), and American sycamore (Platanus occidentalis) was investigated in a slough of the Illinois River, Benton County, Arkansas, using 5-gram packs in wire baskets. Oak and sycamore showed similar degradation rates, while maple was processed much faster. All processing rates were strongly retarded during a period of siltation. Chironomid larvae were the dominant organisms associated with the packs and their numbers were depressed by the silt influx. Shredders were notably few in number as compared with studies from the northwestern United States.
Soil Traversing Arthropod Populations As Sampled By Pitfall Traps In Sunflower And Three Adjacent Habitats In Northeast Arkansas, Linda A. Lee, Harvey E. Barton
Soil Traversing Arthropod Populations As Sampled By Pitfall Traps In Sunflower And Three Adjacent Habitats In Northeast Arkansas, Linda A. Lee, Harvey E. Barton
Journal of the Arkansas Academy of Science
Soil traversing arthropod populations were sampled by pitfall traps in sunflower (Helianthus spp.) and three adjacent habitats during the months of July, August and September of 1980 and May, June, July and August of 1981. In1980, four varieties of sunflower (Ellar, Hybrid 670, 891 and S-345) were planted. A single variety of sunflower (Ellar) was planted in1981. The three adjacent habitats in both 1980 and 1981 were a pine stand, grass border and fence row. Of 1,748 specimens collected in 1980, 17 orders and 48 families were represented. Four orders comprised 78% of the total catch: Hymenoptera (45%), Acari (17%), …

Macroinvertebrate Utilization Of Leaf Detritus In A Riffle Of The Illinois River, Arkansas, Arthur V. Brown, Janet P. Ricker
Macroinvertebrate Utilization Of Leaf Detritus In A Riffle Of The Illinois River, Arkansas, Arthur V. Brown, Janet P. Ricker
Journal of the Arkansas Academy of Science
Small (5 g) leaf packs were placed in a shallow riffle area of the Illinois River in western Benton County, Arkansas, and sequentially retrieved after various exposure times during the winter and spring of 1980. Oak leaves (Quercus shumardii) were utilized more rapidly (9.2% remaining after 91 days), followed by oak/sycamore (Q. shumardii/Platanus occidentalis) leaf packs (31.8% remaining after 91 days). Sycamore {P. occidentalis) was the slowest processed type (32.2% remaining after 91 days). The initial colonization by shredders as characteristic of northern U S. streams did not occur in this study. Collector organisms were present in the leaf packs …
Reported Animal Rabies In Arkansas: 1950-1981, Gary A. Heidt
Reported Animal Rabies In Arkansas: 1950-1981, Gary A. Heidt
Journal of the Arkansas Academy of Science
Reported animal rabies in Arkansas is reviewed for the years 1950-81 . Total cases ranged from 44 in 1969 to 332 in 1979, with a mean of 154. Domestic animals accounted for 72.5% of the total cases until 1961-63 and then declined to 15.8% from 1964-81. This switch from domestic to wildlife rabies corresponded to a similar trend in nationally reported rabies and was probably due to increased public awareness and the vaccination of domestic dogs and cats. Over the 31 year period a total of 18 species of mammals has been implicated in reported rabies (individual species of foxes, …
Continuation Of Spider Research In Arkansas: East Central Ozark Mountain Area, Mary L. Beck, Peggy Rae Dorris
Continuation Of Spider Research In Arkansas: East Central Ozark Mountain Area, Mary L. Beck, Peggy Rae Dorris
Journal of the Arkansas Academy of Science
A preliminary study of spiders concentrated in the eastern section of the Ozark Mountain Area was made for the purpose of determining spider fauna in an on-going research effort to elucidate the total spider fauna of the entire state. At present, 247 species of spiders have been reported.
Invertebrate Fauna Of Devils Den, A Sandstone Cave In Northwestern Arkansas, Stewart B. Peck, James H. Peck
Invertebrate Fauna Of Devils Den, A Sandstone Cave In Northwestern Arkansas, Stewart B. Peck, James H. Peck
Journal of the Arkansas Academy of Science
The same invertebrate fauna of 17 species was found in Devils Den Cave, Washington County, Arkansas, in 1969 and 1979. The fauna consists of 1 trogloxene, 14 troglophiles, and 2 troglobites, a spider, Porrhomma cavernicolum, and a collembolan, Pseudosinella dubia. Devils Den Cave has a well developed cavernicolous fauna, although it is in sandstone which generally supports a poor cave adapted fauna. The troglobites probably evolved in the vicinity of northwestern Arkansas in limestone caves or in deep forest soils of the Ozark region. They then dispersed overland, perhaps as recently as the late Wisconsinan, to occupy this sandstone cave.
Warmwater Fish Community Of A Cool Tailwater In Arkansas, Richard A. Frietsche
Warmwater Fish Community Of A Cool Tailwater In Arkansas, Richard A. Frietsche
Journal of the Arkansas Academy of Science
A diverse warmwater fish community has persisted in the Lake Greeson tailwater, despite hydropower releases of cold hypolimnetic water. Forty-eight species of fish were collected by electrofishing in the upper 16.1 km of the tailwater. Hydropower releases have reduced the abundance of some of the warmwater sport fish in the upper tailwater, and their populations are probably maintained in part by recruitment from downstream. Angling effort has been diverted from the warmwater sport fish populations to a put-and-take trout fishery.

River Otter In Arkansas: Ii. Indications Of A Beaver-Facilitated Commensal Relationship, C. Renn Tumlison, Mark R. Karnes, Anthony W. King
Journal of the Arkansas Academy of Science
Dam building activities of beaver (Castor canadensis) create ponds that apparently augment habitat available to otter (Lutra canadensis). This paper considers possible effects of beaver activity and pond formation on distribution and populations of otter in Arkansas. Literature synthesis and analysis of harvest records were used to investigate the suspected relationship.

Leaf Detritus Processing In An Ozark Cave Stream, Arthur V. Brown, Mark D. Schram
Leaf Detritus Processing In An Ozark Cave Stream, Arthur V. Brown, Mark D. Schram
Journal of the Arkansas Academy of Science
Detritus processing rates and mechanisms were investigated in an Ozark cave stream using post oak (Quercus stellata) leaf packs. The 5 g leaf packs lost ca. 30% of their dry weight within 84 days, resulting in a calculated K value of 0.05. This was an unexpectedly high rate of utilization. Diversity of invertebrates associated with the leaf packs was very low. Stygobromus ozarkensis (Amphipoda) was the only shredder. The two isopods, Caecidotea stiladactyla and Lirceus sp. were the only collectors observed other than a single species of oligochaete worm. Our data indicated that leaf detritus processing rates are virtually independent …
