Three-Dimensional Home Range Of The Eastern Fox Squirrel, Sciurus Niger, Joi L. Augustin Jan 1981

Three-Dimensional Home Range Of The Eastern Fox Squirrel, Sciurus Niger, Joi L. Augustin

Masters Theses

Standard procedures for presenting home range data for species such as the fox squirrel on a single plane do not adequately represent the space they occupy. Comparisons of techniques for presenting the home range of this species on a three-dimensional basis were made using data obtained by direct observations of color marked squirrels. Three-dimensional ellipsoid models of their range varied from 9,154 m3 to 63,811 m3 and were assumed to be more accurate when observation points approached 50 in number. Rectangular parallelepipeds for the same data ranged from 9,784 m3 to 56,836 m3 and resulted in …


A Redescription Of Spironoura Duyagi From The Stomach Of Malayan Box Turtles (Cuora Amboinensis), Rex A. Kuye Jan 1981

A Redescription Of Spironoura Duyagi From The Stomach Of Malayan Box Turtles (Cuora Amboinensis), Rex A. Kuye

Masters Theses

Two hundred and twenty-six worms taken from the stomachs of three Malayan box turtles (Cuora amboinensis) were studied. The worms were identified as Spironoura spp., and their numerical measurements and morphological details compared to other described species in the genus. The nematodes, generally, conformed to published descriptions of Spironoura duyagi, but varied so widely with regards to presence or absence of key diagnostic features that a complete taxonomic analysis was undertaken.


Gastrointestinal Cestodes And Nematodes Of Coyotes From Southeastern Illinois, Valerie Keener Jan 1981

Gastrointestinal Cestodes And Nematodes Of Coyotes From Southeastern Illinois, Valerie Keener

Masters Theses

Gastrointestinal tracts of 45 coyotes, Canis latrans, from southeastern Illinois were examined for cestodes and nematodes. The following parasites and incidences (%) were observed: Taenia sp. (71.1); Physaloptera sp. (53.3); Ancylostoma sp. (20.0); Ascarididae (11.1); Thelazia sp. (2.2); Trichuris sp. (2.2); Uncinaria sp. (2.2). Ancylostoma sp. occurred significantly more often in juveniles than adults. Parasites averaged low numbers per coyote, and no ulceration or blood in the tracts was seen.


The Distribution And Relative Abundance Of Aquatic Oligochaeta In The Upper Cache River System, Southern Illinois, In Relation To Water Quality, Mark Julian Wetzel Jan 1981

The Distribution And Relative Abundance Of Aquatic Oligochaeta In The Upper Cache River System, Southern Illinois, In Relation To Water Quality, Mark Julian Wetzel

Masters Theses

Species composition, distribution, abundance, and water quality relationships of aquatic oligochaetes occurring in the upper Cache River system, southern Illinois were investigated. Forty-two taxa of oligochaetes including 16 naidids, 22 tubificids and representatives of the families Aeolosomatidae, Branchiobdellidae, Enchytraeidae, and Lumbriculidae were collected. Four species of oligochaetes new to Illinois, Limnodrilus psammophilus Loden, L. rubripenis Loden, Psammoryctides (Spencerius) californianus Brinkhurst, and Haemonais waldvogeli Bretscher were collected during this study. Another species of Limnodrilus new to science is reported here, as yet undescribed. The thesis that aquatic oligochaetes can be used as true water quality indicator organisms is rejected. It is …


Description And Taxonomic Importance Of Penial Morphology In The Cryptodiran Turtles Of Malaysia, Lynn D. Wike Jan 1981

Description And Taxonomic Importance Of Penial Morphology In The Cryptodiran Turtles Of Malaysia, Lynn D. Wike

Masters Theses

This paper investigates the use of penial structure to study the relationships among the turtles of peninsular Malaysia. The penial morphology of Malaysian turtles, mainly batagurines, has not been previously described. Herein penes of 12 Malaysian species are described and compared to three Nearctic species. Each was coded for 22 penial characters which were used for numerical analysis by the NT-SYS numerical taxonomy system of multivariate statistical proceedures. The analysis failed to distinguish groups below the family level when the 15 species were tested. The test also failed to distinguish the complexes within the Batagurinae when they were analyzed separately. …
