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 …
Species-Area Model Predicting Diversity Loss In An Artificially Flooded Cave In Brazil, Rodrigo L. Ferreira, Thais G. Pellegrini
Species-Area Model Predicting Diversity Loss In An Artificially Flooded Cave In Brazil, Rodrigo L. Ferreira, Thais G. Pellegrini
International Journal of Speleology
Subterranean environments are poorly known regarding many ecological aspects, such as community structure and its response to different disturbances. To estimate the effects of ground area lost in a limestone cave community in Southeastern Brazil, the invertebrate fauna was sampled before 76% of the cave floor was submerged by the filling of a hydroeletric power plant reservoir. Then, a 2-year monitoring was conducted. A species-area curve based on empiric data was constructed and the z-value of the species-area equation was calculated, what allowed estimating the expected cave richness after flooding comparing with data obtained during the monitoring. The results support …

© 2017, Springer International Publishing AG Switzerland. Despite a well-developed theoretical basis for the role of genetic diversity in the colonization process, contemporary investigations of genetic diversity in biological invasions have downplayed its importance. Observed reductions in genetic diversity have been argued to have a limited effect on the success of establishment and impact based on empirical studies; however, those studies rarely include assessment of failed or comparatively less-successful biological invasions. We address this gap by comparing genetic diversity at microsatellite loci for taxonomically and geographically paired aquatic invasive species. Our four species pairs contain one highly successful and one …

There is a lack of consistency with respect to the use of the terms like species richness, diversity and biodiversity, which extends to the analysis of diversity indices and the merit of using diversity indices in the evaluation (comparison and contrast) of biological communities. The purpose of this article is to provide working definitions for these terms and cite examples from the primary literature that demonstrate the utility of estimating richness, evaluating proportional abundance patterns, as well as comparing indices of diversity and similarity to study patterns of biological organization at different ecological scales. Additionally, we provide a manual in …
