I would also like to dedicate this dissertation to Matt Inman and Jibbers Crabst who gave me the inspiration to tough it out and finish, even during times of crisis. Last, but not least I would like to dedicate this to all my teachers, my parents, everyone whose has shed blood that made this all possible and Ms. Aubree Zenone. Without their support, none of this would have been possible. iv ACKNOWLEDGMENTS My dissertation is the product of started as a simple undergraduate research project that blossomed into the what it is today. None of this would be possible without the immeasurable help that I received along the way. My major professor/advisor/life coach, Dr. Heather Bracken-Grissom, who taught me, all about the various facets of real science, provided me with just the right motivation and support to keep me moving forward with lots of fun along the way, how to communicate even if it is uncomfortable, and last but not least how to work around people no matter how terrible and disagreeable that person may be. She also taught be how to better manage personal and work relationships, and how to keep a better work/life balance… Thanks boss lady! I also want to thank Dr. Eirin-Lopez, who taught me epigenetics and the effects the environment can have on evolution, and for offering his encouragement along the way; Dr. Eric Cole, whom I meet as an undergrad. He taught me a lot about bushwhacking and San Sal, he was always a helpful sounding board for ideas and places to travel, and he is truly one of the most positive people I have ever met; Dr. Eric Bishop von Wettberg, who helped guide me through population genetics and gave me a lot of helpful feedback on useful software to tryout and experimental design; Dr. Jessica Siltberg-Liberles, for teaching sound bioinformatics practices and providing me feedback on all of my bioinformatics questions; Dr. Dean Whitman who helped me understand my results on a geographic timeline and to puzzle out important events in the geologic record; and Dr. Demian Chapman, who happily took over the spot of a committee member that had left the university. I am grateful to the members of the CRUSTOMICS lab for all of their help over the years, especially Dr. Jorge Pérez-Moreno for putting up with my shenanigans; v Dr. Laura Timm, for letting me pick her brain; and Dr. Daniel Deleo for being the best postdoc anyone can ask for and whom helped turn my PhD experience into a positive one. I would like to say, thank you, to William “Bill” Chamberlain, whom I do not think the Marine Science program or the Marine Science Program, cheers. I am also very grateful to Drs. Rob Erdman (Big Rob), Anna Goebel, Randy Cross and the rest of the FGCU Marine Science faculty. They gave me amazing guidance early on during my undergrad and I cannot say how much I appreciate them. I offer my thanks to Ms. Claire Burgett and Ms. Aubree Zenone, who taught me to value all perspectives, whose friendship helped me through many difficulties along the way, and Claire taught me how to art ☺. And, of course, I would like to thank my parents. I would also like to thank Drs. Thomas Iliffe, T.-Y. Chan, Darryl Felder, Craig Layman and Jocelyn Curtis-Quick and the Cape Eleuthera Institute, The Bahamas for their assistance in the collection of specimens. I also thank the curators at USNM and MNHN for providing valuable additional material of Parhippolyte. I would like to thank Dr. John E. Mylroie for his valuable feedback and assistance. I also extend my gratitude to Drs. Raymond Bauer for his expert advice and feedback. I am grateful for the support and assistance of the Gerace Research Centre and Bahamian citizens during field work on San Salvador, Bahamas. These studies were supported in part by a student research award from the Gerace Research Centre, The Crustacean Society - Graduate Student Fellowship, The National Speleological Society - Ralph Stone Graduate Fellowship Grant, and Florida International University Tropics graduate research grant awarded to RED. Additional support was provided by Florida International University. vi ABSTRACT OF THE DISSERTATION CONNECTIONS IN THE UNDERWORLD: A MORPHOLOGICAL AND MOLECULAR STUDY OF DIVERSITY AND CONNECTIVITY AMONG ANCHIALINE SHRIMP by Robert E Ditter Florida International University, 2020 Miami, Florida Professor Heather D. Bracken-Grissom, Major Professor 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 identifiable geographic distribution. Updated range descriptions of Macrobrachium lucifugum Holthuis, 1974, Parhippolyte sterreri (Hart & Manning, 1981) and B. cubensis in the western Atlantic are provided with observations on the behavior of B. cubensis from over 10 years of work. Molecular phylogenetic analyses of a combination of two mitochondrial and five nuclear gene regions are used for molecular barcoding, to further investigate PhyV and to vii re-examine the current classification of the family Barbouriidae. The results find no evidence of cryptic speciation, or genetic differentiation among individuals of B. cubensis (n=72). Morphological and molecular evidence supports synonymizing Janicea within Parhippolyte and recognition of the sub-families Calliasmatinae Ditter et al., 2020 and Barbouriinae Christoffersen, 1987. Connectivity among anchialine systems and population structure of B. cubensis across the tropical western Atlantic is examined using a combination of next generation molecular tools. Genomic analyses suggest a single highly connected population of B. cubensis with low genetic diversity and a low effective population size, which conflicts with the generally accepted isolation paradigm of anchialine systems. Our findings support the value added to genomic studies by generating a partial draft genome constructed using de novo hybrid assembly of short read RADseq and Nanopore long read sequencing data through the investigation of the anchialine isolation paradigm.

Examples of such characters include terminal eyestalk spines, gross spination of the tel- son and the presence of sensory dorsal organs on the carapace. The source and extent of morpholog- ical variation in these shrimp remains unclear, but may be due to environmental or genetic causes, or a combination of both. We note that rampant vari- ation is observed in taxonomically important char- acters that were previously considered highly con- served and therefore were used to discriminate among species of shrimp. If these characters are highly variable then the taxonomic identity of shrimp in this group may need to be reconsidered.

Pérez-Moreno1*, Thomas M. Iliffe2, and Heather D. Bracken-Grissom1 1Department of Biological Sciences, Florida International University, Biscayne Bay Campus, North Miami FL 33181, USA 2Department of Marine Biology, Texas A&M University at Galveston, Galveston, TX 77553, USA Abstract: Anchialine caves contain haline bodies of water with underground connections to the ocean and limited exposure to open air. Despite being found on islands and peninsular coastlines around the world, the isolation of anchialine systems has facilitated the evolution of high levels of endemism among their inhabitants. The unique characteristics of anchialine caves and of their predominantly crustacean biodiversity nominate them as particularly interesting study subjects for evolutionary biology. However, there is presently a distinct scarcity of modern molecular methods being employed in the study of anchialine cave ecosystems. The use of current and emerging molecular techniques, e.g., next-generation sequencing (NGS), bestows an exceptional opportunity to answer a variety of long-standing questions pertaining to the realms of speciation, biogeography, population genetics, and evolution, as well as the emergence of extraordinary morphological and physiological adaptations to these unique environments. The integration of NGS methodologies with traditional taxonomic and ecological methods will help elucidate the unique characteristics and evolutionary history of anchialine cave fauna, and thus the significance of their conservation in face of current and future anthropogenic threats.

In males, endopod of second pair 5 of pleopods (abdominal appendages) with appendix masculina only. Third and fourth pleopods single-branched. Telson generally armed with a pair of fixed lateral spines. Colour: body colour varies from dark brown to reddish; often with distinct spots or colour markings on carapace and/or abdomen - such colour markings are specific and very useful in distinguishing the species. Habitat, biology, and fisheries: All members of this family are marine and can be found from shallow to deep waters (to depths of more than 400 m). They are all benthic and occur on both soft and hard bottoms. Their sizes are generally small, about 2 to 8 cm, but some species can reach a body length over 15 cm. The sexes are easily distinguished by the presence of a large copulatory organ (petasma) on the first pair of pleopods of males, while the females have the posterior thoracic sternites modified into a large sperm receptacle process (thelycum) which holds the spermatophores or sperm sacs (usually whitish or yellowish in colour) after mating.

    Lysmata amboinensis (de Man, 1888) B. Santhosh, M. K. Anil and Biji Xavier IDENTIFICATION Order : Decapoda Family : Lysmatidae Common/FAO : Pacific cleaner Name (English) shrimp Local names:names Not available MORPHOLOGICAL DESCRIPTION The Pacific cleaner shrimp is easily identified by its colour patterns. The body is light brown with one white band dorsally and two red bands laterally running longitudinally. The tail has two white spots on either side. The antennae are white in colour and the first pair has red coloured base. It grows up to a maximum of 6 cm. Source of image : RC CMFRI, Vizhinjam 363 PROFILE GEOGRAPHICAL DISTRIBUTION Scarlet cleaner shrimp or Pacific cleaner shrimp is one of the most popular species of ornamental crustaceans distributed in the waters of the Indo-Pacific region in Indonesia and Sri Lanka. HABITAT AND BIOLOGY It is one of the popular marine shrimp, associated with coral reefs and compatible with smaller sized marine ornamental fishes. It hides in the near shore, shallow and protected areas within a temperature range of 25-30 °C. In the Indo-Pacific areas and the Red Sea, it is mostly found in caves and crevices of coral reefs. It especially needs shelter from predators when it is moulting. It is an omnivore and a scavenger and often feeds on the external parasites of fishes. As its name indicates, this species cleans fishes including moray eels and groupers feeding on their external parasites as well as on mucous and dead or injured tissue. The shrimp moults once every 3-8 weeks and spawns regularly every 2-3 weeks.
