Lactate Dehydrogenase Isozyme Patterns From Five Species Of Snakes : Comparison Of Rattlesnake Vibratory Muscle With Body Epaxial Muscle, Cecil Bernard Cross

Master's Theses

Lactate dehydrogenase (LDH) isozyme patterns of seven tissues in each of five species of snakes are described from their polyacrylamide gel electrophoretic characteristics. The tissues examined included vibratory tail muscle, non­ vibratory tail muscle, body epaxial muscle, heart muscle, whole blood, liver and kidney. The species of snakes included Crotalus adamanteus, C. h. horridus, Agkistrodon piscivorus and Sistrurus miliarius barbouri from the family Crotalidae and Natrix taxispilota from the family Colubridae. These snakes show a decreasing continuum of tail vibratory activity, respectively, to N. taxispilota, which has a non­vibratory tail muscle.

Crotalus adamanteus, C. h. horridus and A. piscivorus have …

Environmental Cues In The Seasonal Development Of The Southern California Annual Grassland, George E. Johnson

Loma Linda University Electronic Theses, Dissertations & Projects

Annual grasslands characteristically experience a succession of seasonal phases which provide for the coexistence of various species by allowing them to make their major demands upon environmental resources at different times. Thus, an ecosystem furnishing certain resources at a limited rate is enabled to support a larger total biomass.

The grasslands of southern California consist principally of annual grasses coexisting with the few remaining native perennial grasses. Characteristic also is the inclusion of forbs which are distinctly either early spring or late summer plants. Many spring forbs, annual grasses, and summer forbs are observed to germinate in approximAte unison shortly …

The Induction Of Thy -1.2 Antigen Expression In Murine Bone Marrow Cells Incubated In Vitro With Immune Serum, Terry Knight

Masters Theses & Specialist Projects

Adult BALB/c mice were immunized with C57BL/6 spleen cells first on day 0 and again on day 8 of the experimental procedure. Serum was collected from these animals on day 0 (before the first immunization), day 4, day 8 (before the second immunization), day 12, and day 16. Two groups of normal BALB/c bone marrow cell suspensions were incubated with the experimental immune sera: and one of the groups of cell suspensions was subsequently incubated with bacterial lipopolysaccharide. Following the incubation steps, both groups of cell preparations were assayed for their ability to absorb the activity of the anti-Thy-1.2 serum. …

The Effect Of Architectural Variation In Habitat On A Spider Community: An Experimental Field Study -- With Special Reference To Resource Partitioning, James Vincent Robinson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spider community acceptance of, and segregation by, architectural configuration was investigated for the spiders of Green Canyon in northern Utah. Modular habitat units consisting of 30.48 centimeter (1 foot) cubes of chicken wire supporting internal strands of macrame jute tied in different orthogonal configurations were used. Configurations including all three axes were tested at two strand densities.

The primary null hypothesis tested, that spider species use structures independent of architecture, was rejected in favor of the alternate hypothesis that spider species differentially use structures dependent upon architecture. Of the eight most abundant species, two showed preferences for horizontal substrata and …

Distribution Of Etheostoma Nigrum Rafinesque, Etheostoma Olmstedi Storer, And Their Introgressive Hybrid Populations In The James River Drainage, John Edward Clark

Master's Theses

An analysis of proportional measurements and meristic characters of Etheostoma nigrum and E. olmstedi identified five populations within the James River drainage. Etheostoma nigrum inhabited the montane and piedmont areas through the Fall Line; E. o. atromaculatum was distributed throughout the tidal river and its lower tributaries; and E. o. olmstedi was restricted to creeks on the upper coastal plain. Appomattox River and Falling Creek contained introgressive hybrid populations with character frequency distributions intermediate to those of E. nigrum and E. o. olmstedi. It is proposed that E. nigrum probably entered these drainages through stream piracy on piedmont tributaries of …

Antipredative Function Of The Gelatinous Coating Of The Eggs Of The Frog, Rana Pipiens, Walter Stanley Jennings

Master's Theses

The eggs of Rana pipiens, the southern leopard frog, were offered in several forms to Lepomis macro­ chirus, the bluegill. The fish were offered random trial discrimination tests while in groups of one or five in 40 1 aquaria. L. macrochirus learned to make distinct discriminations and rejected fertilized and unfertilized egg masses, boiled egg masses, dried frog eggs and gelatin made with homogenated frog eggs. In contrast, Shrimp-el-etts, Shrimp-el-etts dyed black, gelatin made with peptone, and ovarian eggs were accept­ ed readily. The results suggest a protective function for the gelatinous coat: both physical and chemical . The chemical …
