Genetics And Morphology Of Invasive Tubastraea Species Within The Gulf Of Mexico: A Case Study Of Species Misidentification And Distribution, Amelia E. Mcclure
Genetics And Morphology Of Invasive Tubastraea Species Within The Gulf Of Mexico: A Case Study Of Species Misidentification And Distribution, Amelia E. Mcclure
Theses and Dissertations
The invasive corals, Tubastraea coccinea and Tubastraea micrathus, are known to thrive in reefs within the Gulf of Mexico (GOM). Many studies have indicated that species within this genus are spreading throughout the western Atlantic due to their successful invasion on degraded and artificial reef systems. In the Northern GOM, artificial reefs have been created from decommissioned oil rigs and sunken vessels to provide a hard substrate for coral growth. Although, this method is demonstrating success, it is also facilitating, the dispersal of undesired species. The species, T. coccinea and T. micranthus, were thought to be the only …
The Functional, Ecological, And Evolutionary Morphology Of Sea Lampreys (Petromyzon Marinus), Bradley Morgan Wood
The Functional, Ecological, And Evolutionary Morphology Of Sea Lampreys (Petromyzon Marinus), Bradley Morgan Wood
LSU Doctoral Dissertations
Lampreys (Petromyzontiformes) are jawless vertebrates with an evolutionary history lasting at least 360 million years and are often used in comparisons with jawed vertebrates because some of their morphological aspects, such as the segmented trunk musculature with curved myosepta and a non-mineralized skeleton fibrous skeleton, are thought to resemble the condition of early vertebrates before the evolution of jaws. Although earlier authors studied the morphology of the skeleto-muscular system of the trunk of lampreys, their studies are not detailed and complete enough to allow a functional and biomechanical analysis that is needed as a basis for modeling the mechanics of …
Morphometric Analysis Of Subfossil Macronycteris Spp. (Chiroptera: Hipposideridae) From Madagascar, Jamie Lynn Alumbaugh
Morphometric Analysis Of Subfossil Macronycteris Spp. (Chiroptera: Hipposideridae) From Madagascar, Jamie Lynn Alumbaugh
Graduate Research Theses & Dissertations
Macronycteris bats are morphologically conservative between species but demonstrate intraspecific morphological variation between geographic locations and sexes. Two of the four living species of Macronycteris are found on Madagascar, where they are broadly distributed and demonstrate a trend in body size correlated with the latitudinal precipitation cline on the western side of the island. The presence of an extinct species, M. besaoaka, from Anhjohibe Cave in northern Madagascar suggests that Macronycteris was once more diverse, at least with respect to morphology. Since its description, taxonomic and phylogenetic revisions have reshaped our understanding of this genus. On Madagascar, these include the …
