Accurate identification of fishes is essential for understanding their biology and to ensure food safety for consumers. DNA barcoding is an important tool because it can verify identifications of both whole and processed fishes that have had key morphological characters removed (e.g., filets, fish meal); however, DNA reference libraries are incomplete, and public repositories for sequence data contain incorrectly identified sequences. During a nine-year sampling program in the Philippines, a global biodiversity hotspot for marine fishes, we developed a verified reference library of cytochrome c oxidase subunit I (COI) sequences for 2,525 specimens representing 984 species. Specimens were primarily purchased …


Haplotype Network Branch Diversity, A New Metric Combining Genetic And Topological Diversity To Compare The Complexity Of Haplotype Networks, Eric Garcia, Daniel Wright, Remy Gatkins, May B. Roberts, Hudson T. Pinheiro, Eva Salas, Jei-Ying Chen, Jacob R. Winnikoff, Giacomo Bernardi Jan 2021

A common way of illustrating phylogeographic results is through the use of haplotype networks. While these networks help to visualize relationships between individuals, populations, and species, evolutionary studies often only quantitatively analyze genetic diversity among haplotypes and ignore other network properties. Here, we present a new metric, haplotype network branch diversity (HBd), as an easy way to quantifiably compare haplotype network complexity. Our metric builds off the logic of combining genetic and topological diversity to estimate complexity previously used by the published metric haplotype network diversity (HNd). However, unlike HNd which uses a combination of network …


Using Genetics To Inform Restoration And Predict Resilience In Declining Populations Of A Keystone Marine Sponge, Sarah M. Griffiths, Evelyn D. Taylor-Cox, Donald C. Behringer, Mark J. Butler Iv, Richard F. Preziosi Feb 2020

Using Genetics To Inform Restoration And Predict Resilience In Declining Populations Of A Keystone Marine Sponge, Sarah M. Griffiths, Evelyn D. Taylor-Cox, Donald C. Behringer, Mark J. Butler Iv, Richard F. Preziosi

Genetic tools can have a key role in informing conservation management of declining populations. Genetic diversity is an important determinant of population fitness and resilience, and can require careful management to ensure sufficient variation is present. In addition, population genetics data reveal patterns of connectivity and gene flow between locations, enabling mangers to predict recovery and resilience, identify areas of local adaptation, and generate restoration plans. Here, we demonstrate a conservation genetics approach to inform restoration and management of the loggerhead sponge (Spheciospongia vesparium) in the Florida Keys, USA. This species is a dominant, habitat-forming component of marine ecosystems in …


Isolation And Characterization Of Eight Polymorphic Microsatellites For The Spotted Spiny Lobster, Panulirus Guttatus, Nathan Truelove, Donald C. Behringer, Mark J. Butler Iv, Richard F. Preziosi Jan 2016

Isolation And Characterization Of Eight Polymorphic Microsatellites For The Spotted Spiny Lobster, Panulirus Guttatus, Nathan Truelove, Donald C. Behringer, Mark J. Butler Iv, Richard F. Preziosi

Biological Sciences Faculty Publications

Microsatellite sequences were isolated from enriched genomic libraries of the spotted spiny lobster, Panulirus guttatus using 454 pyrosequencing. Twenty-nine previously developed polymerase chain reaction primer pairs of Panulirus argus microsatellite loci were also tested for cross-species amplification in Panulirus guttatus. In total, eight consistently amplifying, and polymorphic loci were characterized for 57 individuals collected in the Florida Keys and Bermuda. The number of alleles per locus ranged from 8 to 20 and observed heterozygosities ranged from 0.409 to 0.958. Significant deviations from Hardy–Weinberg equilibrium were found in one locus from Florida and three loci from Bermuda. Quality control testing indicated …


Hidden Diversity In Sardines: Genetic And Morphological Evidence For Cryptic Species In The Goldstripe Sardinella, Sardinella Gibbosa (Bleeker, 1849), Rey C. Thomas, Demian A. Willette, Kent E. Carpenter, Mudjekeewis D. Santos Jan 2014

Hidden Diversity In Sardines: Genetic And Morphological Evidence For Cryptic Species In The Goldstripe Sardinella, Sardinella Gibbosa (Bleeker, 1849), Rey C. Thomas, Demian A. Willette, Kent E. Carpenter, Mudjekeewis D. Santos

Biological Sciences Faculty Publications

Cryptic species continue to be uncovered in many fish taxa, posing challenges for fisheries conservation and management. In Sardinella gibbosa, previous investigations revealed subtle intra-species variations, resulting in numerous synonyms and a controversial taxonomy for this sardine. Here, we tested for cryptic diversity within S. gibbosa using genetic data from two mitochondrial and one nuclear gene regions of 248 individuals of S. gibbosa, collected from eight locations across the Philippine archipelago. Deep genetic divergence and subsequent clustering was consistent across both mitochondrial and nuclear markers. Clade distribution is geographically limited: Clade 1 is widely distributed in the central Philippines, while …

Microbes are the most abundant biological entities found in the biosphere. Identification and measurement of microorganisms (including viruses, bacteria, archaea, fungi, and protists) in the biosphere cannot be readily achieved due to limitations in culturing methods. A non-culture based approach, called “metagenomics”, was developed that enabled researchers to comprehensively analyse microbial communities in different ecosystems. In this study, we highlight recent advances in the field of metagenomics for analyzing microbial communities in different ecosystems ranging from oceans to the human microbiome. Developments in several bioinformatics approaches are also discussed in context of microbial metagenomics that include taxonomic systems, sequence databases, …
