Abundance And Diversity Of Deep-Sea Crustaceans Of Bear Seamount, New England Seamount Chain, Valerie Miranda
Abundance And Diversity Of Deep-Sea Crustaceans Of Bear Seamount, New England Seamount Chain, Valerie Miranda
HCAS Ocean Science Research Symposium
Bear Seamount (39° 55’ N; 67° 30’ W) is the westernmost peak of extinct undersea volcanoes in the New England Seamount Chain (Moore et al., 2003). It is located on the continental slope off Georges Bank, and is governed by unique environmental factors and currents that may be unlike those of the other seamounts (Moore et al., 2003). Previous cruises to this seamount have been successful in capturing abundant fishes, cephalopods and invertebrates (Moore et al., 2003; Moore et al., 2004; Moore et al., 2008), but only the distribution patterns of the fishes and cephalopods have been examined, leaving a …
Vision And Bioluminescence In Deep-Sea Crustaceans, Tamara Frank
Vision And Bioluminescence In Deep-Sea Crustaceans, Tamara Frank
HCAS Ocean Science Research Symposium
Adaptations of the visual systems of deep-sea crustaceans to dim light environments are driven not only by environmental light, but also biologically produced light, or bioluminescence. In the pelagic zone, the relationship is driven, at least in part, by intrinsic bioluminescence. The unusual possession of UV sensitivity, in additional to the expected blue sensitivity, in several species of deep-sea crustaceans appears to be linked to their two modes of bioluminescence. In the benthic zone, the relationship is not so clear. On several NOAA-OER funded research expeditions, electrophysiological studies were conducted on a number of species of decapod crustaceans collected with …
Monitoring A Problem: Evaluating The Ecological Status Of The Invasive Nile Monitor In Florida And Forecasting Population Expansion Using Computational Gis, Noah Cohen
HCAS Ocean Science Research Symposium
The state of Florida is an epicenter for the introduction of exotic terrestrial and marine species, often which are attributed to the pet industry. Identifying the threats posed by exotics that may become invasive is critical to manage and protect indigenous species and habitats. One such exotic that is now invasive in Florida is the Nile Monitor (Varanus niloticus). The Nile monitor is a large, predatory lizard native to central and southern Africa that is thought to have been introduced to Florida via both intentional and unintentional releases associated with the exotic pet trade. Since their introduction, Nile monitors have …
Genomic Assembly Analyses Of Asian Teleost Species Seabass (Lates Calcarifer) And Arowana (Scleropages Formosus), Stephen O'Brien
Genomic Assembly Analyses Of Asian Teleost Species Seabass (Lates Calcarifer) And Arowana (Scleropages Formosus), Stephen O'Brien
HCAS Ocean Science Research Symposium
The genome assembly and annotation of Asian seabass (Lates calcarifer) , a marine teleost with aquaculture relevance will be described, an initiative of Genome 10K . Though > 500 eukaryotic genome sequences are available in public repositories, the majority are highly fragmented with incomplete assemblies, so considerable effort and resources are often spent to improve their quality. In the present study, PacBio long read sequencing , genetic and optical mapping, and syntenic inference were combined to build a chromosome-length assembly with a contig N50 size over 1 Mb and scaffold N50 size over 25 Mb that span ~90% of the genome …
If You Build It, Will They Come? Exploring Enhancements To Artificial Structure For Use In Restoration And Mitigation Applications In The Mexican Caribbean, Kirk Kilfoyle
HCAS Ocean Science Research Symposium
A study involving standardized artificial reef modules (ReefballsTM) was conducted in Puerto Morelos, Mexico. The purpose was to explore the use of artificial structure in restoration and mitigation projects in a Caribbean coral reef environment similar to South Florida by applying select experimental treatments hypothesized to accelerate their acquisition of a natural coral reef assemblage. Multiple hypotheses on the progression and interaction between artificial structure and the resulting fish, coral, algal, and non-coral invertebrate assemblages were examined. Each of 40 reefball modules received one of 4 treatments (10 modules/treatment): invertebrate substrate pads, coral transplants, settlement plates, or control. Following deployment, …
