Abstract

Our understanding of marine communities and their functions in an ecosystem relies on the ability to detect and monitor species distributions and abundances. Currently, the use of environmental DNA (eDNA) metabarcoding is increasingly being applied for the rapid assessment and monitoring of aquatic species. Most eDNA metabarcoding studies have either focussed on the simultaneous identification of a few specific taxa/groups or have been limited in geographical scope. Here, we employed eDNA metabarcoding to compare beta diversity patterns of complex pelagic marine communities in tropical coastal shelf habitats spanning the whole Caribbean Sea. We screened 68 water samples using a universal eukaryotic COI barcode region and detected highly diverse communities, which varied significantly among locations, and proved good descriptors of habitat type and environmental conditions. Less than 15% of eukaryotic taxa were assigned to metazoans, most DNA sequences belonged to a variety of planktonic "protists," with over 50% of taxa unassigned at the phylum level, suggesting that the sampled communities host an astonishing amount of micro‐eukaryotic diversity yet undescribed or absent from COI reference databases. Although such a predominance of micro‐eukaryotes severely reduces the efficiency of universal COI markers to investigate vertebrate and other metazoans from aqueous eDNA, the study contributes to the advancement of rapid biomonitoring methods and brings us closer to a full inventory of extant marine biodiversity.

10. Undergraduate Research at The School for Field Studies' (SFS) Center for Marine Resource Studies in the Turks and Caicos Islands.

Abstract

The School for Field Studies' (SFS) Center for Marine Resource Studies (CMRS) has been actively engaged in undergraduate research in the Turks and Caicos Islands (TCI) for over 20 years. The undergraduate research is guided and influenced by local stakeholders and focuses on local marine resources. One avenue of research explored by students is the status of the Caribbean queen conch fishery. SFS provides data on both the status of the fishery and consumption of conch to the TCI Department of Environment and Maritime Affairs (DEMA) to inform resource-management decisions. Under the Convention on International Trade in Endangered Species of Wild Fauna and Flora, this department is responsible for monitoring and managing queen conch, and the undergraduate research conducted at the marine center is integral to providing data to support those efforts. A recent survey of national seafood consumption conducted by the undergraduates showed that domestic consumption of conch was underestimated, leading to export quotas that could lead to overfishing of this particular mollusk. The students also work with the community and the local stakeholders to improve the understanding of management decisions based on unbiased data collection. [ABSTRACT FROM AUTHOR]

11. ASSESSING 50-YEAR CHANGE IN BAHAMIAN REEF FISH ASSEMBLAGES: EVIDENCE FOR COMMUNITY RESPONSE TO RECENT DISTURBANCE?

Abstract

The article presents a study on the reef fish community structure off the coast of New Providence Island in The Bahamas. It discusses details of the findings based on a resurvey of the community in 2006 and comparisons with baseline data from 1955 to 1973 to determine if there had been changes in diversity over the 50-year period. It highlights the importance of monitoring the areas, particularly the prevalence of the invasive lionfish, Pterois volitans.

Abstract

A global survey of coral reefs reveals that overfishing is driving resident shark species toward extinction, causing diversity deficits in reef elasmobranch (shark and ray) assemblages. Our species-level analysis revealed global declines of 60 to 73% for five common resident reef shark species and that individual shark species were not detected at 34 to 47% of surveyed reefs. As reefs become more shark-depleted, rays begin to dominate assemblages. Shark-dominated assemblages persist in wealthy nations with strong governance and in highly protected areas, whereas poverty, weak governance, and a lack of shark management are associated with depauperate assemblages mainly composed of rays. Without action to address these diversity deficits, loss of ecological function and ecosystem services will increasingly affect human communities.

Abstract

Sharks are charismatic predators that play a key role in most marine food webs. Their demonstrated vulnerability to exploitation has recently turned them into flagship species in ocean conservation. Yet, the assessment and monitoring of the distribution and abundance of such mobile species in marine environments remain challenging, often invasive and resource-intensive. Here we pilot a novel, rapid and non-invasive environmental DNA (eDNA) metabarcoding approach specifically targeted to infer shark presence, diversity and eDNA read abundance in tropical habitats. We identified at least 21 shark species, from both Caribbean and Pacific Coral Sea water samples, whose geographical patterns of diversity and read abundance coincide with geographical differences in levels of anthropogenic pressure and conservation effort. We demonstrate that eDNA metabarcoding can be effectively employed to study shark diversity. Further developments in this field have the potential to drastically enhance our ability to assess and monitor elusive oceanic predators, and lead to improved conservation strategies.
