A Biosystematic Study Of The Fern Genus Lygodium In Eastern North America, Violet M. Brown
A Biosystematic Study Of The Fern Genus Lygodium In Eastern North America, Violet M. Brown
Retrospective Theses and Dissertations
The mainly tropical genus Lygodium differs from other ferns in that the fronds are indeterminate and are vine-like. A single species, L. palmatum is native in temperate North America. The temperate Asian L. japonicum is naturalized throughout much of the southeastern United States. About twenty years ago, L. microphyllum was introduced into South Florida and is now naturalized in several counties. The present study documents differences among spores and their generation, development of sporophytes from the fertilized egg, and in flavonoid chemistry. Hybridization experiments showed a strong possibility for cross fertility between species. Experiments with prothallial development and differentiation revealed …

The Reproductive Biology Of Sternotherus Minor Minor (Reptilia: Testudines: Kinosternidae) From The Southern Part Of Its Range In Central Florida, Cory R. Etchberger
The Reproductive Biology Of Sternotherus Minor Minor (Reptilia: Testudines: Kinosternidae) From The Southern Part Of Its Range In Central Florida, Cory R. Etchberger
Retrospective Theses and Dissertations
Variation in chelonian reproductive patterns is well documented. Previous studies of loggerhead musk turtles (Sternotherus minor) reproduction have not attempted to control for variation in latitude, local population differences, and seasonal variation. The present study attempts to control for these variables by collecting turtles from one population for one reproductive season. The reproductive pattern of S. minor at the southern limit of its range (Central Florida) is compared to those of S. minor studied elsewhere. Both male and female musk turtles mature after five to six years and at approximately 60mm plastron length. No sexual dimorphism in overall body size …
The Effects Of Beach Restoration On Marine Turtles' Nesting In South Brevard County, Florida, Paul W. Raymond
The Effects Of Beach Restoration On Marine Turtles' Nesting In South Brevard County, Florida, Paul W. Raymond
Retrospective Theses and Dissertations
The south Brevard coast of Florida is a major nesting ground for the Atlantic loggerhead turtle (Caretta caretta). A beach restoration project was completed in the winter of 1980-81 at Indialantic and Melbourne Beach. A study was conducted to investigate the effects of beach restoration on marine turtle nesting during the summer months of 1981 and 1982. A 3.1 km restored beach study area and two control beach study areas, each 3.1 km in length and consisting of natural beach sands, were established. The entire study area (9.3 km) was monitored for nesting and non-nesting emergences (false crawls) and a …
