A Spatial Inquiry Of Infant Low Birthweight And Cancer Mortality In East Baton Rouge Parish, Louisiana, Esra Qzdenerol
A Spatial Inquiry Of Infant Low Birthweight And Cancer Mortality In East Baton Rouge Parish, Louisiana, Esra Qzdenerol
LSU Historical Dissertations and Theses
Infant low birthweight rate in East Baton Rouge Parish is higher compared to the nation. Cancer is one of the most serious health problems in Louisiana. A few studies have indicated a relationship between the two health outcomes and their environment, but conclusions from these studies have not always been consistent. The spatial and temporal scales of the data and the methods used in these studies contribute to the inconsistent and uncertain results. The spatial patterns of infant low birthweight and cancer mortality in East Baton Rouge Parish from 1993 to 1996 and their relationships with environmental factors at three …
The Breeding Ecology Of White-Faced Ibis In The Lower Carson River Basin, Nevada, Eric Patrick Kelchlin
The Breeding Ecology Of White-Faced Ibis In The Lower Carson River Basin, Nevada, Eric Patrick Kelchlin
LSU Historical Dissertations and Theses
The Great Basin White-faced Ibis (Plegadis chihi) population is recognized as a Species of Management because of its small population size, limited number of traditional breeding sites, and vulnerability to habitat loss. The ability to predict future population trends and develop wetland management strategies is limited because many aspects of their breeding ecology and population dynamics are unknown. 1 examined White-faced Ibis nesting ecology and breeding habitat selection at the Lower Carson River Basin, Nevada, from 1995-1997, and the relationship between the local surface water conditions and trends in the number of breeding pairs from 1970-1997 on a local and …
Positive Selection And Propeptide Repeats Promote Rapid Interspecific Divergence Of A Gastropod Sperm Protein, Michael E. Hellberg, Gary W. Moy, Victor D. Vacquier
Positive Selection And Propeptide Repeats Promote Rapid Interspecific Divergence Of A Gastropod Sperm Protein, Michael E. Hellberg, Gary W. Moy, Victor D. Vacquier
Faculty Publications
Male-specific proteins have increasingly been reported as targets of positive selection and are of special interest because of the role they may play in the evolution of reproductive isolation. We report the rapid interspecific divergence of cDNA encoding a major acrosomal protein of unknown function (TMAP) of sperm from five species of teguline gastropods. A mitochondrial DNA clock (calibrated by congeneric species divided by the Isthmus of Panama) estimates that these five species diverged 2-10 MYA. Inferred amino acid sequences reveal a propeptide that has diverged rapidly between species. The mature protein has diverged faster still due to high nonsynonymous …
Molecular Systematics Of The Green Algal Order Trentepohliales (Chlorophyta)., Juan Manuel Lopez-Bautista
Molecular Systematics Of The Green Algal Order Trentepohliales (Chlorophyta)., Juan Manuel Lopez-Bautista
LSU Historical Dissertations and Theses
Molecular, karyological, and nuclear genome quantification data from representatives of the order Trentepohliales (Chlorophyta) were used to infer evolutionary relationships with other green algal classes and orders. Phylogenetic analyses of the nuclear-encoded small subunit ribosomal DNA (18S rDNA) sequences from taxa representing all of the major lineages of green algae consistently indicated that the subaerial Trentepohliales are closely related to Ulvophycean marine green algae, particularly to the siphonous and hemisiphonous orders. The phylogenetic distribution of continuous and discontinuous types of mitochondrial large subunit ribosomal RNAs (mtLSU rRNA) in green algae has been shown to be consistent with phylogenetic relationships previously …
American Alligator Nesting Ecology In Impounded Marsh Habitat, Louisiana., Steven Richard Reagan
American Alligator Nesting Ecology In Impounded Marsh Habitat, Louisiana., Steven Richard Reagan
LSU Historical Dissertations and Theses
The goal was to monitor a large number of female alligators over a 3-year period to obtain information on alligator nesting ecology. This dissertation, although designed to estimate annual nesting rates, provides additional meaningful information on methods of capture, tag retention rates, nest spacing patterns, segregation of size classes, nest site fidelity, the relationship between attendance and nest success, the effects of fire ants on alligator nest success, the relationship between hatchling alligators and their mother, and hatchling dispersal. Passive integrated transponder (PIT), monel web, and cranial mounted reflector tags were evaluated for marking and identifying alligators. Use of harmonic …

Ecology Of Seagrass Fishes And Macroinvertebrates On Guatemala's Atlantic Coast., Alejandro Arrivillaga
Ecology Of Seagrass Fishes And Macroinvertebrates On Guatemala's Atlantic Coast., Alejandro Arrivillaga
LSU Historical Dissertations and Theses
The ecology of fishes and macroinvertebrates inhabiting shallow seagrass beds was studied at Bahia La Graciosa, located in Amatique Bay in the Caribbean coast of Guatemala. The study area included extensive turtle grass, Thalassia testudinum, meadows over muddy substrate, whereas a more exposed shoreline also supported turtle grass meadows over sandy substrates outside the bay. A total of 166 samples were collected across two seasons and habitat types in three sampling trips to the area with a cylindrical drop sampler. Diversity and abundance of fishes and macroinvertebrates inhabiting seagrass and adjacent bare-sand sites were described to assess the relative importance …
