Taxonomic Resolution Assessment And Biodiversity Evaluations For Deep-Sea Fish Assemblages In A Pelagic Ecosystem Of The Northern Gulf Of Mexico, Krista N. Scheuerman
Taxonomic Resolution Assessment And Biodiversity Evaluations For Deep-Sea Fish Assemblages In A Pelagic Ecosystem Of The Northern Gulf Of Mexico, Krista N. Scheuerman
All HCAS Student Capstones, Theses, and Dissertations
Knowledge of community assemblages and biodiversity is important for monitoring health and resilience in an ecosystem. Taxonomic and functional biodiversity of mesopelagic (200- 1000 m) fishes is extremely rich in the Gulf of Mexico. The aim of this study was to compare calculations of biodiversity and community structures at varying taxonomic resolutions for deep pelagic fishes to inform future decisions about deep-sea ecosystem monitoring. This study analyzed biodiversity and assemblage structure patterns from a biological inventory of deep-sea fishes collected with a large mesh, commercial-sized, high-speed rope trawl in the Gulf of Mexico between June 21st and July 14 …
A Revision Of The Genera Of Charitometridae With Abruptly Expanded Genital Pinnules, Alois Romanowski
A Revision Of The Genera Of Charitometridae With Abruptly Expanded Genital Pinnules, Alois Romanowski
HCNSO Student Theses and Dissertations
Feather star (Echinodermata: Crinoidea: Comatulida) family Charitometridae has not been revised since 1950. Molecular analysis, new specimens of existing species, and the discovery of a new species has revealed the need for a generic-level revision of those genera that exhibit abruptly expanded genital pinnules. A morphological study was conducted using 57 specimens representing 10 species of the Charitometridae. The genus Poecilometra is redescribed, and two species formerly placed in Strotometra have been moved to the genus based primarily on possession of pedunculate genital pinnules and a wide flange on the first pinnular of the proximal pinnules. A new species was …
