IDENTIFYING MARINE KEY BIODIVERSITY AREAS IN THE GREATER CARIBBEAN REGION by Michael S. Harvey B.A. May 2013, Old Dominion University A Thesis Submitted to the Faculty of Old Dominion University in Partial Fulfillment of the Requirements for the Degree of MASTER OF SCIENCE BIOLOGY OLD DOMINION UNIVERSITY August 2018 Approved by: Kent E. Carpenter (Advisor) Beth Polidoro (Member) Sara Maxwell (Member) ABSTRACT IDENTIFYING MARINE KEY BIODIVERSITY AREAS IN THE GREATER CARIBBEAN REGION Michael S. Harvey Old Dominion University, 2018 Advisor: Dr. Kent E. Carpenter Anthropocene biodiversity extinction rates are increasing, suggesting a possible sixth global mass extinction event. Biological conservation planners are consequently seeking ways to more effectively protect species at national, regional and global scales. In 2010, the Convention on Biological Diversity (CBD) issued a number of conservation goals (Aichi Targets), including the establishment of protected areas (PA) in terrestrial, freshwater and marine areas of eminent conservation concern by 2020 to reduce and eventually eliminate species’ extinctions, as well as preserve hotspots of biodiversity and dynamic ecosystems. While well- established, adequately enforced PAs increase the likelihood of preserving species and habitats most at risk of extirpation, traditional methods of choosing where to place PAs are frequently inadequate in targeting biodiversity most in need of conservation. The International Union for Conservation of Nature (IUCN), therefore, formulated a set of criteria and thresholds using quantitative and transparent selection methods to iteratively identify sites where species and habitats are most urgently in need of protection. The identification of these Key Biodiversity Areas (KBAs) utilizes species-specific spatial occurrence and population data and species’ threat statuses, to locate areas where site-specific protection measures can effectively slow or halt the extinction of species. This study uses species-specific data provided on IUCN’s Red List website and other online data repositories to identify marine KBAs in the Greater Caribbean region using the newly refined, 2016 IUCN KBA criteria and thresholds in order to address the question of if these criteria are effective for marine environments and to understand how this process may improve PA site selection in the greater Caribbean region. Even though previous analyses have identified marine KBAs for threatened species, this study is one of the first attempts to identify KBAs for geographically restricted species in the marine environment. The identified KBAs provide logical starting points for local stakeholders and conservation specialists to verify KBA thresholds and boundaries using localized national and regional datasets. Furthermore, this study will identify significant data gaps in the knowledge of marine species’ occurrences that may prevent the full application of the KBA criteria to all marine species. iv Copyright, 2018, by Michael S.

Frank L. Pezold, PhD Chris Bird, PhD Chair Committee Member Kevin W. Conway, PhD James D. Hogan, PhD Committee Member Committee Member Lea-Der Chen, PhD Graduate Faculty Representative December 2014 ABSTRACT The family of fishes commonly known as gobies (Teleostei: Gobiidae) is one of the most diverse lineages of vertebrates in the world. With more than 1700 species of gobies spread among more than 200 genera, gobies are the most species-rich family of marine fishes. Gobies can be found in nearly every aquatic habitat on earth, and are often the most diverse and numerically abundant fishes in tropical and subtropical habitats, especially coral reefs. Their remarkable taxonomic, morphological and ecological diversity make them an ideal model group for studying the processes driving taxonomic and phenotypic diversification in aquatic vertebrates. Unfortunately the phylogenetic relationships of many groups of gobies are poorly resolved, obscuring our understanding of the evolution of their ecological diversity. This dissertation is a multi-scale phylogenetic study that aims to clarify phylogenetic relationships across the Gobiidae and demonstrate the utility of this family for studies of macroevolution and speciation at multiple evolutionary timescales.

E-mail: [email protected] 2Universidade Federal do Espírito Santo, Brazil. E-mail: [email protected], [email protected] 3Texas A&M University - Corpus Christi, Texas, USA. E-mail: [email protected] Abstract It is unclear how many species of Gobiosoma occur in Brazil and what their geographic distributions are. Here we combine data from a comprehensive morphological survey and a molecular analysis to clarify this uncertain taxonomy and place Brazilian Gobiosoma within a phylogenetic framework. Recent collections in Brazil, from the states of Ceará to Santa Catarina, and in Uruguay yielded two allopatric species of Gobiosoma that are distinct in genetics, meristics, morphomet- rics, scale pattern and coloration. Comparisons were made with types and specimens of Gobiosoma hemigymnum, Gar- mannia mediocricula, Gobiosoma spilotum and Gobiosoma parri and all other known species of Gobiosoma. We place G. parri in synonomy with G. hemigymnum with a distribution of Rio de Janeiro to Uruguay and Argentina. The northern species, that extends from the states of Espírito Santo to Ceará, is described as a new species, Gobiosoma alfiei.

    06_250317 part1-3.qxd 12/13/05 7:32 PM Page 15 Phylum Chordata Chordates are placed in the superphylum Deuterostomia. The possible rela- tionships of the chordates and deuterostomes to other metazoans are dis- cussed in Halanych (2004). He restricts the taxon of deuterostomes to the chordates and their proposed immediate sister group, a taxon comprising the hemichordates, echinoderms, and the wormlike Xenoturbella. The phylum Chordata has been used by most recent workers to encompass members of the subphyla Urochordata (tunicates or sea-squirts), Cephalochordata (lancelets), and Craniata (fishes, amphibians, reptiles, birds, and mammals). The Cephalochordata and Craniata form a mono- phyletic group (e.g., Cameron et al., 2000; Halanych, 2004). Much disagree- ment exists concerning the interrelationships and classification of the Chordata, and the inclusion of the urochordates as sister to the cephalochor- dates and craniates is not as broadly held as the sister-group relationship of cephalochordates and craniates (Halanych, 2004). Many excitingCOPYRIGHTED fossil finds in recent years MATERIAL reveal what the first fishes may have looked like, and these finds push the fossil record of fishes back into the early Cambrian, far further back than previously known. There is still much difference of opinion on the phylogenetic position of these new Cambrian species, and many new discoveries and changes in early fish systematics may be expected over the next decade. As noted by Halanych (2004), D.-G. (D.) Shu and collaborators have discovered fossil ascidians (e.g., Cheungkongella), cephalochordate-like yunnanozoans (Haikouella and Yunnanozoon), and jaw- less craniates (Myllokunmingia, and its junior synonym Haikouichthys) over the 15 06_250317 part1-3.qxd 12/13/05 7:32 PM Page 16 16 Fishes of the World last few years that push the origins of these three major taxa at least into the Lower Cambrian (approximately 530–540 million years ago).

    State of research of the Osteichthyes fish related to coral reefs in the Honduran Caribbean with catalogued records Estado del conocimiento de los peces osteíctios asociados a los arrecifes de coral en el Caribe de Honduras, con registros catalogados Anarda Isabel Salgado Ordoñez1, Julio Enrique Mérida Colindres1* & Gustavo Adolfo Cruz1 ABSTRACT Research on Honduran coral reef fish has been isolated and scattered. A list of fish species related to coral reefs was consolidated to establish a compiled database with updated taxonomy. The study was conducted between October 2017 and December 2018. Using primary and secondary sources, all potential species in the Western Atlantic were considered, and their actual presence was confirmed using catalogued records published in peer-reviewed journals that included Honduras. In addition, the specimens kept in the Museum of Natural History of Universidad Nacional Autónoma de Honduras were added. Once the list was consolidated, the taxonomic status of each species was updated based on recent literature. A total of 159 species and 76 genera were registered in 32 families. The family with the most species was Labrisomidae with 27 species (17%). Five families had more than five 5 genera registered, while four 4 were represented by more than 16 species, which is equivalent to 42% genera and 51% species. Gobiidae was represented by 10 genera (13%) and 21 species (13%), of which two 2 were endemic: Tigrigobius rubrigenis and Elacatinus lobeli. In turn, Grammatidae was represented by one endemic species Lipogramma idabeli (1.8%). The species Diodon holocanthus and Sphoeroides testudineus represent the first catalogued records for Honduras.
