Dna Barcoding Enhances Large-Scale Biodiversity Initiatives For Deep-Pelagic Crustaceans Within The Gulf Of Mexico And Adjacent Waters, Carlos Varela
Dna Barcoding Enhances Large-Scale Biodiversity Initiatives For Deep-Pelagic Crustaceans Within The Gulf Of Mexico And Adjacent Waters, Carlos Varela
FIU Electronic Theses and Dissertations
In this dissertation I investigate the biodiversity of marine deep-water crustaceans of the Gulf of Mexico and adjacent waters, focusing on pelagic crustaceans. Taxonomic and molecular techniques were utilized to document adult and larval crustacean specimens to better under their taxonomy, life history, evolutionary relationships and cryptic biodiversity. The use of molecular techniques to study organisms from habitats with limited accessibility provides tremendous potential. With prevalent anthropogenic threats and the delicate nature of deep-water habitats, the need to improve our understanding of these systems is clear. Molecular techniques can act as a fundamental tool to complement traditional taxonomy. The application …
Taxonomy And Systematics Of Plumeria L. (Apocynaceae) In The Caribbean Islands, Nichole M. Tiernan
Taxonomy And Systematics Of Plumeria L. (Apocynaceae) In The Caribbean Islands, Nichole M. Tiernan
FIU Electronic Theses and Dissertations
Plumeria L. (Apocynaceae) is a genus of flowering trees and shrubs that are often cultivated in tropical gardens worldwide. The majority of its species occur in the Greater Antilles with many as single-island endemics. The only comprehensive revision for the genus was done by Robert E. Woodson Jr. (1937) who recognized only seven species and created a ‘Plumeria obtusa complex’ with a plethora of synonyms. The first study provides an overview of the Caribbean Island members of the genus with a focus on Plumeria filifolia Griseb., a thin-leaved species endemic to Cuba that is featured because of its incredible …
Connections In The Underworld: A Morphological And Molecular Study Of Diversity And Connectivity Among Anchialine Shrimp., Robert Eugene Ditter
Connections In The Underworld: A Morphological And Molecular Study Of Diversity And Connectivity Among Anchialine Shrimp., Robert Eugene Ditter
FIU Electronic Theses and Dissertations
This research investigates the distribution and population structure of crustaceans, endemic to anchialine systems in the tropical western Atlantic focusing on cave-dwelling shrimp from the family Barbouriidae. Taxonomic and molecular tools (genetic and genomic) are utilized to examine population dynamics and the presence of phenotypic hypervariation (PhyV) of the critically endangered species Barbouria cubensis (von Martens, 1872). The presence of PhyV and its geographic distribution is investigated among anchialine populations of B. cubensis from 34 sites on Abaco, Eleuthera, and San Salvador, Bahamas. Examination of 54 informative morphological characters revealed PhyV present in nearly 90% (n=463) of specimens with no …
Systematic Studies In Myrtaceae Of The Greater And Lesser Antilles, Jonathan A. Flickinger
Systematic Studies In Myrtaceae Of The Greater And Lesser Antilles, Jonathan A. Flickinger
FIU Electronic Theses and Dissertations
The Myrtaceae, or myrtle family, are a group of flowering trees and shrubs represented in the Americas by over 2000 species of the predominantly Neotropical tribe Myrteae. Recent progress on the challenging systematics of the group has been achieved through molecular phylogenetics, but few of the almost 500 species endemic to the islands of the Greater and Lesser Antilles in the Caribbean have been included in either phylogenetic or revisionary studies. The purpose of my dissertation is therefore to contribute to the description and phylogenetic classification of Antillean Myrtaceae. The first study describes Eugenia walkerae, a new species of …
