Growth, Mortality, Food Habits, And Fecundity Of The Buffalo River Smallmouth Bass, Raj V. Kilambi, Walter R. Robison, James C. Adams

Journal of the Arkansas Academy of Science

Total length-scale radius, and length-weight relationships were determined for smallmouth bass from the Buffalo River. The back calculated lengths were used in analyzing the age-length data by the Bertalanffy growth formula. Asymptotic length and weight were estimated as 58.3 cm and 4.6 lbs, respectively. Annual mortality of 36 percent was estimated by the catch curve method. Insects (54%), fishes (16%), and crayfish (14%) were the abundant food organisms by frequency of occurrence; while fishes (64%) and crayfish (29%) were the dominant food items by the gravimetric method. Based on the gonosomatic indices and frequency distribution of ovum diameter measurements, smallmouth …

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.

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 …
