Bacterial Acquisition In Juveniles Of Several Broadcast Spawning Coral Species, Koty H. Sharp, Kim B. Ritchie
Bacterial Acquisition In Juveniles Of Several Broadcast Spawning Coral Species, Koty H. Sharp, Kim B. Ritchie
Arts & Sciences Faculty Publications
Coral animals harbor diverse microorganisms in their tissues, including archaea, bacteria, viruses, and zooxanthellae. The extent to which coral-bacterial associations are specific and the mechanisms for their maintenance across generations in the environment are unknown. The high diversity of bacteria in adult coral colonies has made it challenging to identify species-specific patterns. Localization of bacteria in gametes and larvae of corals presents an opportunity for determining when bacterial-coral associations are initiated and whether they are dynamic throughout early development. This study focuses on the early onset of bacterial associations in the mass spawning corals Montastraea annularis, M. franksi, M. faveolata, …
Effects Of Salinity On Reproduction And Survival Of The Calanoid Copepod Pseudodiaptomus Pelagicus, Cortney L. Ohs, Andrew L. Rhyne, Scott W. Grabe, Matthew A. Dimaggio, Erik Stenn

Four experiments were conducted on the calanoid copepod, Pseudodiaptomus pelagicus, to determine the effects of salinity on survival, development time, reproductive output, and population growth in order to define the optimal salinity for culture. To determine the appropriate experimental salinity range we exposed nauplii and adults to abrupt salinity changes from 35 g/L to 5, 10, 15, 35, 42, and 48 g/L at 30 °C and determined survival after 24 hours. The second experiment stocked early stage nauplii into 1 L beakers after which they were cultured using standard procedures for 10 days at six salinities (10, 15, 20, …

As the world’s largest importer of marine ornamental species for the aquaria, curio, home décor, and jewelry industries, the United States has an opportunity to leverage its considerable market power to promote more sustainable trade and reduce the effects of ornamental trade stress on coral reefs worldwide. Evidence indicates that collection of some coral reef animals for these trades has caused virtual elimination of local populations, major changes in age structure, and promotion of collection practices that destroy reef habitats. Management and enforcement of collection activities in major source countries such as Indonesia and the Philippines remain weak. Strengthening US …
The Importance Of Open Access In Technology Transfer For Marine Ornamental Aquaculture: The Case Of Hobbyist-Led Breeding Initiative, Andrew L. Rhyne
The Importance Of Open Access In Technology Transfer For Marine Ornamental Aquaculture: The Case Of Hobbyist-Led Breeding Initiative, Andrew L. Rhyne
Arts & Sciences Faculty Publications
Access to peer-reviewed literature is often restricted to a limited segment of the target audience. Barriers are in place to prevent open access information. Here, I present a case study of how the internet and hobbyists are transforming both access and flow of information from closed circles to open dialogue within the field of marine ornamental fish rearing. This open approach is leading to innovation a rate remarkably faster and at a lower costs than could have been accomplished by traditional methods. Aquaculture societies, aquarium professionals, hobbyists, and scientists pursuing the captive production of species should embrace this movement. Whether …
The Evolution Of Euhermaphroditism In Caridean Shrimps: A Molecular Perspective Of Sexual Systems And Systematics, G. Curt Fiedler, Andrew L. Rhyne, Ryoko Segawa, Tadashi Aotsuka, Nikolaos V V. Schizas

The hippolytid genus Lysmata is characterized by simultaneous hermaphroditism, a very rare sexual system among Decapoda. Specialized cleaning behavior is reported in a few pair-living species; these life history traits vary within the genus. Unfortunately, the systematics of Lysmata and the Hippolytidae itself are in contention, making it difficult to examine these taxa for trends in life history traits. A phylogeny of Lysmata and related taxa is needed, to clarify their evolutionary relationships and the origin of their unique sexual pattern. In this study, we present a molecular phylogenetic analysis among species of Lysmata, related genera, and several putative …

Coral animals harbor diverse microorganisms in their tissues, including archaea, bacteria, viruses, and Bryostatins are a family of protein kinase C modulators that have potential applications in biomedicine. Found in miniscule quantities in a small marine invertebrate, lack of supply has hampered their development. In recent years, bryostatins have been shown to have potent bioactivity in the central nervous system, an uncultivated marine bacterial symbiont has been shown to be the likely natural source of the bryostatins, the bryostatin biosynthetic genes have been identified and characterized, and bryostatin analogues with promising biological activity have been developed and tested. Challenges in …
