Assessing Population Genetic Structure Of Eastern Phoebes At A Migratory Stopover Site, Daniel Jones
Assessing Population Genetic Structure Of Eastern Phoebes At A Migratory Stopover Site, Daniel Jones
Biology Theses
Migration is an energetically costly and stressful event and migratory stopover sites are important areas along the migratory route that birds stop at to rest and refuel. Migration timing and routes vary across and even within species, including differences between sexes, ages and populations. Most genetic studies of migratory birds occur on breeding grounds, but when breeding locations are not known, it is likely that genetic patterns can be assessed accurately at migratory stopover sites if certain conditions exist. First, if a species is philopatric – where individuals return to the same sites every year, gene flow across geographically separated …
Incidence And Prevalence Of Francisella Noatunensis Subsp. Orientalis (Fno) Pathogenic Infections In Feral Hawaiian Tilapia, Daquille Peppers
Incidence And Prevalence Of Francisella Noatunensis Subsp. Orientalis (Fno) Pathogenic Infections In Feral Hawaiian Tilapia, Daquille Peppers
Biology Theses
Aquaculture has become a major food source for many countries and continues to grow each year. However, many of the fishes that are farmed are susceptible to pathogenic infections such as Francisellosis, a bacterial infection that contributes to disease and high mortality rate in many populations of farmed and wild fish around the world. In 1994, feral and farmed populations of tilapia (e.g. Oreochromis mossambicus) on Oahu, Hawaii were found to be infected with a novel Francisellosis strain, Francisella noatunensis subsp. orientalis (Fno). To prevent the spread of this pathogen, the Hawaii Department of Aquaculture (HDOA) initiated …
A Polyphasic Approach In Understanding Green Algal Ecology, Blia Lor
A Polyphasic Approach In Understanding Green Algal Ecology, Blia Lor
Biology Theses
Pithophora and Cladophora are two representative genera of the order Cladophorales as filamentous Chlorophyta. These two genera are major contributors to the total algal biomass of littoral communities in freshwater and shallow marine water and have been reported as nuisance algae as they proliferate fast with the influx of nutrients. However, the wide geographical distribution and the overlap of plastic morphological characteristics between the two genera have complicated taxonomic identification at species level and phylogenetic studies. In the present study, a population of a monospecific, filamentous algal community was collected in Jewell, Georgia from the Ogeechee River. The monospecific, filamentous …
