Fishes Of Crowley's Ridge In Arkansas, Robert F. Fulmer, George L. Harp Jan 1977

Fishes Of Crowley's Ridge In Arkansas, Robert F. Fulmer, George L. Harp

Journal of the Arkansas Academy of Science

Crowley's Ridge is one of the six natural geographic divisions of Arkansas which rises out of the Mississippi embayment as a relatively steep, uncultivated loessial mass. The ridge is drained by a network of headwater streams which are relatively clear with alkaline pH values and uniformly low alkalinity values. Carbon dioxide values were moderate and oxygen values were adequate. The fish species collected were basically headwater in composition. Isolated groups of characteristically upland species indicate that environmental quality of adjacent deltaic streams was better at one time.

Forest Communities Of Crowley's Ridge, G. Thomas Clark Jan 1977

Forest Communities Of Crowley's Ridge, G. Thomas Clark

Journal of the Arkansas Academy of Science

The forest communities of Crowley's Ridge in Arkansas were surveyed by sampling 22 selected stands which met predetermined criteria. The Importance Value (I.V.) for each woody species over one decimeter, diameter breast height (dbh), was derived from the combined values of relative density, relative dominance by basal area (B.A.), and relative frequency. Young trees under one decimeter, dbh, were assigned to three height classes from which frequency, density, and stratification data were derived. White Oak-Red Oak-Hickory is the general forest type. Its subdivisions: Oak-Hickory-Pine Forest, Mixed Oak-Hickory Forest, and White Oak-Beech Forest are advocated for practical field references. They are …

Macrobenthos Population Changes In Crystal Lake, Arkansas, Subsequent To Cage Culture Fish, James C. Adams, Raj V. Kilambi, William A. Wickizer, Arthur V. Brown

Journal of the Arkansas Academy of Science

A three-year study was conducted to determine the possible effects of cage culture of fish on the environment of Crystal Lake, Arkansas. The investigation consisted of three periods: pre- (November 1971-October 1972), during- (November 1972-October 1973), and post- (November 1973-October 1974) cage culture. Numbers and biomass of benthos per square meter for pre-, during-, and post-culture periods were 1353 (10.0g), 730 (8.8g), and 1028 (4.1g), respectively. Numerically, Chaoborus sp., Chironomidae, and Oligochaeta comprised more than 97%. Chaoborus was the most numerous organism before fish culture (>68%), but dominance shifted to the Oligochaeta (>58%) after culture.

Castanea Pumila Var. Ozarkensis (Ashe) Tucker, Comb. Nov, Gary E. Tucker Jan 1975

Castanea Pumila Var. Ozarkensis (Ashe) Tucker, Comb. Nov, Gary E. Tucker

Journal of the Arkansas Academy of Science

Castanea ozarkensis Ashe, the Ozark chinquapin of the vascular plant family Fagaceae, is distributed widely throughout the Interior Highlands of Arkansas and the adjacent states of Missouri and Oklahoma. Examination of material from throughout the range of C. ozarkensis indicates demonstrable morphological intergradation with C. pumila (L.) Miller sensu lato, the chinquapin of wide distribution in much of the eastern United States. It is proposed that C. ozarkensis be reduced to C. pumila var. ozarkensis (Ashe) Tucker, comb. nov.

Variation In Ligule Spotting In Coreopsis Basalis, Edwin B. Smith Jan 1974

Variation In Ligule Spotting In Coreopsis Basalis, Edwin B. Smith

Journal of the Arkansas Academy of Science

The ligules of Coreopsis basalis bear an attractive reddish-brown spot at the base. The spot has been used as a taxonomic character of the species. But there is variation within populations at any one time, and within individuals at sequential times, for the size of the spot. A few individuals lack the ligule spot entirely. Variation in average ligule spot size in greenhouse-grown populations of C. basalis and an artificial hybrid is described. Average spot size declines as the blooming season progresses. Some individuals with spotted ligules early in the season bore spotless ligules late in the season. No correlation …

Origin Of Grassy Lake, Robert Terry Huffman Jan 1974

Origin Of Grassy Lake, Robert Terry Huffman

Journal of the Arkansas Academy of Science

Two theories have been proposed to explain the formation of Grassy Lake. One attributes the formation of the swamp to earthquake; the other states that it is one of the many so-called oxbow lakes in the area. A study of aerial photographs showing the absence of fault zones and related sandblows tends to rule out any possibility of an earthquake origin, and in size and shape the swamp in no way resembles an oxbow lake. The aerial photographs reveal instead that the formation of the swamp was due to a natural levee being built up by a river which meandered …

Preimpoundment Ichthyofaunal Survey Of The Piney Creek Watershed, Izard County, Arkansas, William J. Matthews, George L. Harp Jan 1974

Preimpoundment Ichthyofaunal Survey Of The Piney Creek Watershed, Izard County, Arkansas, William J. Matthews, George L. Harp

Journal of the Arkansas Academy of Science

Piney Creek is a clear medium-size tributary of White River in a region of the Ozarks that is undergoing rapid environmental change. Piney Creek is characterized by a very diverse ichthyofauna, although increased sedimentation due to poor agricultural practices and gravel mining threatens to destroy much natural habitat and eventually may cause extirpation of some species. The wide diversity of 44 species is related to variety of habitat and the proximity of a large reservoir, and not to differences in the physicochemical environments. Fish density ranged from 15,100 to 21 fish/ha, greatest concentrations being in headwater pools. For the three …
