The Effect Of Divalent Cations On The Prophenoloxidase Enzyme Cascade Activity In The Freshwater Crayfish Cambarus Latimanus, Hans Skailand Eikaas
The Effect Of Divalent Cations On The Prophenoloxidase Enzyme Cascade Activity In The Freshwater Crayfish Cambarus Latimanus, Hans Skailand Eikaas
Theses and Dissertations
The effect of divalent cations such as cadmium, calcium, copper, lead and magnesium upon the prophenoloxidase system (proPO) was studied in hemocytes of the crayfish Cambarus latimanus. It was demonstrated that cadmium, calcium, copper and lead increased proPO activity significantly, whereas magnesium had no statistically significant effect on the system. Also, the molecular weight of the proPO enzyme was estimated using SDS-PAGE and found to be approximately 76 kDa.

A Comparison Of Movements And Burrow Usage Between Indigenous And Relocated Gopher Tortoises (Gopherus Polyphemus) In A Fall Line Sandhills Community, Dorinda Morpeth
A Comparison Of Movements And Burrow Usage Between Indigenous And Relocated Gopher Tortoises (Gopherus Polyphemus) In A Fall Line Sandhills Community, Dorinda Morpeth
Theses and Dissertations
The movements and burrow use of twenty (ten relocated and ten indigenous to the relocation site) adult gopher tortoises {Gopherus polyphemus) were followed during the late spring, summer and early autumn in Talbot County, Georgia. The objectives of this study were to determine whether relocated gopher tortoises developed fidelity to a relocation site, and whether indigenous tortoises reacted adversely to relocated tortoises released in their proximity. Ten tortoises in the right-of-way of a highway construction project were captured, fitted with transmitters, and relocated to a 336 hectare tract of land, 3.2 km east of Geneva, Talbot, County, Georgia. Concurrently, ten …
A Descriptive Survey Of Freshwater Unionidae Bivalves In Five Creeks Located In West Central Georgia, Rufus Carson Stringfellow
A Descriptive Survey Of Freshwater Unionidae Bivalves In Five Creeks Located In West Central Georgia, Rufus Carson Stringfellow
Theses and Dissertations
A descriptive survey of the West Georgia, Chattahoochee River drainage unionid bivalve fauna inhabiting Mountain Oak, Mulberry, Standing Boy, and Upatoi Creeks has been completed. The survey is intended to determine whether Unionidae populations remain extant in this portion of the Chattahoochee River drainage, and to estimate the abundance and distribution of species encountered. Accessibility sampling was employed; sites selected to be surveyed were usually located at a road bridge or some landmark easily identifiable for geographical positioning. Collecting methods included the use of a small rake in sandy or silty substrate, visual detection of siphons or trails in the …
Late Cretaceous Dinosaurs In Eastern Usa—A Taphonomic And Biogeographic Model Of Occurrences., David R. Schwimmer
Late Cretaceous Dinosaurs In Eastern Usa—A Taphonomic And Biogeographic Model Of Occurrences., David R. Schwimmer
Faculty Bibliography
The eastern Coastal Plains of the USA contain a Late Cretaceous dinosaur assemblage of limited taxic diversity, but with wide distribution and reasonably good abundance. The ages of specimens range from Santonian through late Maastrichtian. All Late Cretaceous eastern dinosaur specimens occur in pericontinental or marine strata, and therefore all such fossils are likely to be allochthonous. New materials and insights bear on the taphonomy of these marine occurrences, suggesting that fluvially-transported, floating carcasses, many scavenged by sharks, make up most of the eastern marine dinosaur record. There is little evidence of faunal provinciality across the entire eastern outcrop: fossil …

First Mastodont Remains From The Chattahoochee River Valley In Western Georgia, With Implications For The Age Of Adjacent Stream Terraces, David R. Schwimmer
Faculty Bibliography
Fossils of Mammut americanum, the American Mastodont, have been recovered from a stream in the Chattahoochee River drainage basin. These fossils imply that at least some local stream terraces are of Pleistocene age.
First Dinosaur Fossils From Georgia, With Notes On Additional Cretaceous Vertebrates From The State, David R. Schwimmer
First Dinosaur Fossils From Georgia, With Notes On Additional Cretaceous Vertebrates From The State, David R. Schwimmer
Faculty Bibliography
New Collections of Upper Cretaceous (Campanian) vertebrate fossils from Stewart County, Georgia, contain isolated bones from two dinosaur taxa: a hadrossaur (Ornithischia, Ornithopoda) of undetermined genus, and tyrannosaur (Saurischia, Theropoda) comparable to Albertosaurus. Numerous individuals are represented in the collections. The fossils are found at the upper formational contact of the Blufftown Formation but appear to be redeposited from lower down in the unit. These dinosaur fossils probably represent shore-living or river-transported animals preserved in back-barrier or estuarine pericontinental marine environments of deposition.
