Ichthyofaunal Diversification And Distribution In Jane's Creek Watershed, Randolph County, Arkansas, Cheryl Lynn Fowler, George L. Harp Jan 1974

Ichthyofaunal Diversification And Distribution In Jane's Creek Watershed, Randolph County, Arkansas, Cheryl Lynn Fowler, George L. Harp

Journal of the Arkansas Academy of Science

The purposes of this study were to determine the qualitative and quantitative distribution of fishes in the Jane's Creek watershed. Jane's Creek is a clear, spring-fed Ozark stream in northeastern Arkansas. A knowledge of the ichthyofauna of this stream prior to a long-range impoundment is of significance to the natural history of Arkansas. Jane's Creek and its tributaries were found to be alkaline, with no measurable turbidity, and to have low levels of carbon dioxide. Dissolved oxygen values ranged from 6.1 to 16.0 ppm. Only slight differences in physicochemical conditions were noted among stations and between pool and riffle areas …


New Taxa In Pectis (Compositae: Pectidinae) From Mexico And The Southwestern United States, David J. Keil Jan 1974

New Taxa In Pectis (Compositae: Pectidinae) From Mexico And The Southwestern United States, David J. Keil

Biological Sciences

This paper is the first of a series of investigations on the systematics of Pectis L., the largest genus in the subtribe Pectidinae of the tribe Helenieae. Pectis consists of about one hundred species of annual or perennial, glandular-dotted, yellow-rayed herbs that are widespread in the warmer parts of the New World. In the present report three previously unrecognized taxa from Mexico and the southwestern United States are described as new, and a new combination also is made


Multi-Use Of The Campus Environment In The Teaching Of Botany, Jewel E. Moore Jan 1974

Multi-Use Of The Campus Environment In The Teaching Of Botany, Jewel E. Moore

Journal of the Arkansas Academy of Science

Use of the campus environment in the teaching program is described with special reference to the campus of University of Central Arkansas. Permanent labels identify the campus trees, many of which are representative of native Arkansas trees. A Daylily Display Bed and an Iris Display Bed, both composed of hybrid varieties, are included in the campus design. This organization of the flora of the campus provides a community service as well as an outdoor supplement to the classroom studies in plant science.

Wildlife Habitats In Managed Rangelands-- The Great Basin Of Southeastern Oregon, Wayne Bowers, Bill Hosford, Art Oakley, Carl Bond Jan 1974

Wildlife Habitats In Managed Rangelands-- The Great Basin Of Southeastern Oregon, Wayne Bowers, Bill Hosford, Art Oakley, Carl Bond

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

All land management activities on managed rangelands will have some impact(s) on fish habitat; those in the riparian zone will have the greatest impact(s). Native trout populations in the Great Basin of southeastern Oregon exhibit predictable responses to alterations in their habitats; optimum production of native trout is therefore achievable through careful habitat management.

Fisheries Report No 15 - The Western Rock Lobster Fishery 1972 - 1973, G. R. Morgan, E H. Barker Jan 1974

Fisheries Report No 15 - The Western Rock Lobster Fishery 1972 - 1973, G. R. Morgan, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster* is one of the most important single fisheries in Australia and an important export earner for the State. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and which are designed to limit the total effort to acceptable levels and to enforce a legal minimum size. It is thus important to constantly monitor the state of the fishery both to ensure that the effort is remaining within the accepted limits and that the regulations are adequately performing their function of maintaining reasonably stable catches. Inherent …
