Status Of The Mountain Lion In Arkansas, John A. Sealander, Philip S. Gipson Jan 1973

Status Of The Mountain Lion In Arkansas, John A. Sealander, Philip S. Gipson

Journal of the Arkansas Academy of Science

Two authenticated kill records of the mountain lion, Felis concolor, in Arkansas are reported as well as numerous reliable sight records spanning an approximately 30-year period. Distribution of sightings in the state is discussed in relation to an expanding deer population. The cougar probably never was exterminated in Arkansas but it still may be considered endangered.


Trypanosoma Lewisi Kent (Protozoa: Mastigophora): Ultrastructure And Theory Of Locomotion, Christine Wen Chan, David A. Becker Jan 1972

Trypanosoma Lewisi Kent (Protozoa: Mastigophora): Ultrastructure And Theory Of Locomotion, Christine Wen Chan, David A. Becker

Journal of the Arkansas Academy of Science

Trypanosoma lewisi Kent is a nonpathogenic hemoflagellate of rats (Rattus spp.). After briefly reviewing its infrastructure, the writers postulate that inside the flagellum the change in shape of kinetosomal plate 1 may cause one of the central microtubules and the helical-like structure to contribute to flagellar movement. The energy to run this system may be transferred from the kinetoplast with its associated mitochondrion.


Anatomical And Behavioral Aspects Of Killing And Feeding By The Least Weasel, Mustela Nivalis L., Gary A. Heidt Jan 1972

Anatomical And Behavioral Aspects Of Killing And Feeding By The Least Weasel, Mustela Nivalis L., Gary A. Heidt

Journal of the Arkansas Academy of Science

The least weasel (Mustela nivalis) is a remarkably well adapted predator of mice and other small animals. Each kill is rather stereotyped, in that the weasel grabs the prey by the nape of the neck and bites through the base of the skull and/or throat, using its lithe body to "wrap up" and hold the prey. The least weasel will kill mice successively until it is too exhausted physically to kill more. Mice are always eaten from the head posteriorly until completely consumed.


Herpetofauna Of Sylamore Ranger District, Ozark National Forest, Arkansas: Preliminary Report, John P. Schuier, James W. Dickson, Michael J. Harvey Jan 1972

Herpetofauna Of Sylamore Ranger District, Ozark National Forest, Arkansas: Preliminary Report, John P. Schuier, James W. Dickson, Michael J. Harvey

Journal of the Arkansas Academy of Science

A survey of the amphibians and reptiles of the Sylamore Ranger District, Ozark National Forest, Arkansas, was conducted from May 1969 through May 1972. The district is composed of 170,000 acres and includes parts of Stone, Baxter, Marion, and Searcy Counties. A total of 533 specimens was collected during the study. An additional 72 specimens in the collections of Memphis State University and Arkansas State University were examined. Forty-nine species were recorded from the study area. These consisted of 8 salamanders, 12 frogs and toads, 4 turtles, 6 lizards, and 19 snakes. Two species collected during the study, Scaphiopus holbrooki …


Checklist Of Spiders Collected In Mississippi Compared With Preliminary Study Of Arkansas Spiders, Peggy Rae Dorris Jan 1972

Checklist Of Spiders Collected In Mississippi Compared With Preliminary Study Of Arkansas Spiders, Peggy Rae Dorris

Journal of the Arkansas Academy of Science

This paper presents a comparative list of spiders collected in the 82 counties of Mississippi and in a random sampling of the spiders of Arkansas. The Mississippi list includes 26 families with 263 species, whereas the Arkansas collection includes 24 families with 206 species. Various methods of collecting were used in an effort to sample all populations and to contribute to knowledge of the taxonomy both Mississippi and Arkansas.


Histological Study Of Liver On Channel Catfish, Ictalurus Punctatus, Leland F. Morgans Jan 1972

Histological Study Of Liver On Channel Catfish, Ictalurus Punctatus, Leland F. Morgans

Journal of the Arkansas Academy of Science

Histologically the liver of the channel catfish, Ictalurus punctatus, was found to consist of many lobules. Though not surrounded by a connective tissue sheath as they are in some animals, the lobules were discernable because all the hepatic cells in a particular area radiated from a central vein. Portal triads were scattered throughout the liver. The lobule tissue consisted of radiating cords of cells alternating with sinusoids. Glycogen was condensed into large vacuoles within these cells. Pancreatic tissue was found in the liver, always surrounding a capillary or venule. Morphologically the pancreatic cells were exocrine. Functionally, however, they may be …


Phosphorescent Animal Forms Of Arkansas, Peggy Rae Dorris Jan 1971

Phosphorescent Animal Forms Of Arkansas, Peggy Rae Dorris

Journal of the Arkansas Academy of Science

Two phosphorescent animal forms, Euryurus sp. and Centruroides vittatus, were collected with a black light in an attempt to collect phosphorescent spiders. Both the millipede and the scorpion were easily observed by the bright phosphorescent yellow color which glowed in the presence of the black light
