Fishes Of Morrow Creek, A Lower Ouachita River Tributary, In Southern Arkansas, Henry W. Robison, Stephen A. Winters Jan 1978

Fishes Of Morrow Creek, A Lower Ouachita River Tributary, In Southern Arkansas, Henry W. Robison, Stephen A. Winters

Journal of the Arkansas Academy of Science

The fishes of Moro Creek, a fifth order stream tributary of the lower Ouachita River in southern Arkansas, were sampled from 1972-1977. Field collections, literature records and museum records revealed a total of 63 species representing 14 families. An undescribed cyprinid, the bluehead shiner, is reported from Moro Creek for the first time. In general, longitudinal zonation of fish species was apparent as species diversity increased downstream. Stream inhabitants were typical Coastal Plain fishes of the lower Ouachita River system.

Range And Status Of The Nutria, Myocastor Coypus, In Arkansas, Joe W. Bailey, Gary A. Heidt Jan 1978

Range And Status Of The Nutria, Myocastor Coypus, In Arkansas, Joe W. Bailey, Gary A. Heidt

Journal of the Arkansas Academy of Science

An extensive survey has shown that the current range of the nutria, Myocastor coypus. in Arkansas should include the West Gulf Coastal Plain, the Mississippi Alluvial Plain (to Missouri) and the Arkansas Valley along the Arkansas River to Oklahoma. The extensive river and creek systems in the state have provided ready avenues for dispersal, allowing for extremely rapid expansion from the early 1960's when nutria were first observed in the southern part of the state. The current range probably represents most of the suitable habitat in the state and it is felt that further expansion will be held to a …

Fishes Of The Caddo River, Arkansas, After Impoundment Of Degray Lake, Michael R. Dewey, Thomas E. Moen

Journal of the Arkansas Academy of Science

Fifty-five collections of fishes were made with small-mesh seines and electrofishing gear in the Caddo River and four of its tributaries during 1974-75. Eighty-two species representing 17 families were collected; 14 of the species had not previously been reported from the Caddo River.


Movements Of Channel Catfish And Flathead Catfish In Beaver Reservoir, Northwest Arkansas, Thomas O. Duncan, Milton R. Myers Jr. Jan 1978

Movements Of Channel Catfish And Flathead Catfish In Beaver Reservoir, Northwest Arkansas, Thomas O. Duncan, Milton R. Myers Jr.

Journal of the Arkansas Academy of Science

A total of 497 channel catfish, Ictalurus punctatus, and flathead catfish, Pylodictis olivaris. were tagged in Beaver Reservoir during two November-April tagging periods (1967-68 and 1968-69); total recaptures were 9.5 and 11.7% respectively. The longest time between tagging and recapture was 1622 days (4.4 years) for channel catfish and 494 days (1.4 years) for flathead catfish. The longest distances traveled were 43.1 km by a channel catfish and 44.3 km by a flathead catfish. Fisherman returns indicated that catfish were caught primarily from April through July. The many recaptures, even after long periods, within 1.6 km of the tagging point, …


Fishes Of The Mountain Province Section Of The Ouachita River, John L. Harris, Neil H. Douglas Jan 1978

Fishes Of The Mountain Province Section Of The Ouachita River, John L. Harris, Neil H. Douglas

Journal of the Arkansas Academy of Science

A survey of the fishes of the mountain province section of the Ouachita River from the headwaters to Remmel Dam using field collections, literature records, and museum collections showed the ichthyofauna to be made up of 80 species representing 16 families. Fourteen species not previously reported from the mountain province section of the river were collected in this survey. These species include Ichthyomyzon gagei, Nocomis asper, Notropis ortenburgeri, N. rubellus, Pimephales promelas, Moxostoma carinatum, Noturus taylori, Fundulus notatus, Lepomis humilis, Etheostoma histrio, E. proeliare, Percina maculata, P. nasuta, and P. uranidea. The Nocomis specimens were the first collected from the …


Distribution And Habitat Of The Taillight Shiner, Notropis Maculatus (Hay), In Arkansas, Henry W. Robison Jan 1978

Distribution And Habitat Of The Taillight Shiner, Notropis Maculatus (Hay), In Arkansas, Henry W. Robison

Journal of the Arkansas Academy of Science

The distribution of the taillight shiner, Notropis maculatus (Hay), within Arkansas is discussed based on personal collections, literature citations and a search of museum records. N. maculatus appears to be a typical Coastal Plain physiographic province inhabitant occurring below the Fall Line, and it nears its western and northern range limits west of the Mississippi River in Arkansas. Data are provided on preferred habitat, and suggestions are provided as to the current status of the taillight shiner within Arkansas.

Some Physiological And Morphological Adaptations For Underwater Survival In Natrix Rhombifera And Elaphe Obsoleta, Dennis A. Baeyens, Chris T. Mcallister, Leland F. Morgans Jan 1978

Some Physiological And Morphological Adaptations For Underwater Survival In Natrix Rhombifera And Elaphe Obsoleta, Dennis A. Baeyens, Chris T. Mcallister, Leland F. Morgans

Journal of the Arkansas Academy of Science

The submergence times of the diamondback water snake (Natrix rhombifera) and black rat snake (Elaphe obsoleta) were compared. Both species could easily survive underwater for periods greater than one hour. Furthermore, there was no difference in time of underwater survival in the two species. Some physiological and morphological parameters which may contribute to the ability of N. rhombifera and E. obsoleta to remain submerged were also examined. E. obsoleta was found to have a greater lung volume and larger and more numerous alveoli than N. rhombifera. Both species demonstrated a bradycardia upon submergence but it was less pronounced than the …


Summary Of The Status Of Harvest Mice, Cricetidae: Reithrodontomys, In Arkansas, V. Rick Mcdaniel, John C. Huggins, James A. Huggins, Michael W. Hinson Jan 1978

Summary Of The Status Of Harvest Mice, Cricetidae: Reithrodontomys, In Arkansas, V. Rick Mcdaniel, John C. Huggins, James A. Huggins, Michael W. Hinson

Journal of the Arkansas Academy of Science

Although four species of harvest mice, Reithrodoniomyx, are known to occur in Arkansas, the distributional status of the genus in the state is poorly understood. Recent museum specimens significantly extend the range of R. megalotix and R. fulvescens in the state. R. megalotis is shown to range south through Phillips Co. in eastern Arkansas, and R. fulvescens is shown to range throughout most of the state, now including most of the Mississippi Alluvial Plain. A new specimen of R. humulis from Delaware Co., Oklahoma, suggests that this species probably ranges throughout northwestern Arkansas. R montanus remains known only from Washington …


Species Composition And Diversity Of Hawk Populations In Northeastern Arkansas, Earl L. Hanebrink, Keith B. Sutton, Alan F. Posey Jan 1978

Species Composition And Diversity Of Hawk Populations In Northeastern Arkansas, Earl L. Hanebrink, Keith B. Sutton, Alan F. Posey

Journal of the Arkansas Academy of Science

Species composition and diversity of hawk populations were analyzed for northeastern Arkansas by the use of roadside censuses conducted in September through April from 1974- 1977. Data from 10 years of Jonesboro Christmas Bird Counts were also analyzed. During the roadside survey 20,174 miles were driven and 1819 raptors were counted. Ten species were observed with the Red-tailed Hawk being most abundant followed by the Marsh Hawk and the American Kestrel. Eight species were recorded from the 10 years of Christmas Bird Counts. Annual breeding bird surveys and spot records turned up three additional species making a total of 14 …


Influence Of Lead, An Environmental Pollutant On Metamorphosis Of Rana Utricularia (Amphibia: Ranidae), Gloria L. Yeung Jan 1978

Influence Of Lead, An Environmental Pollutant On Metamorphosis Of Rana Utricularia (Amphibia: Ranidae), Gloria L. Yeung

Journal of the Arkansas Academy of Science

The influence of lead, an environmental pollutant on metamorphosis of Rana utricularia, was examined in this study. Larvae of stage XI (Taylor and Kollros, 1946), beginning of the premetamorphic stage, were exposed to lead concentrations of 0.1 ppm, 0.5 ppm, 1.0 ppm and 1.5 ppm for 106 days. The untreated larvae served as controls. Larvae were observed from early limb bud stage, stage X, through the protrusion of the forelimbs, stage XX. Neither the sequence of developmental events nor the gross external and internal morphology was altered by lead. However, lead prolonged the time of metamorphosis by delaying the completion …
