“…However, there are no reports on the genetic structure of S. marmoratus populations that cover most of the habitat, from Japan to China. Microsatellite markers used in the exploration of population genetic structure usually exhibit co‐dominant inheritance and high diversity, with relatively modest analysis expense (Chong & Roe, ; Du et al, ; Kitson‐Walters et al, ). This study aimed to draw a comprehensive picture of the patterns of genetic diversity and structure along the distribution area in the coastal waters of the northwestern Pacific, across a large latitudinal range, using microsatellite markers.…”

The marbled rockfish (Sebastiscus marmoratus) is an important species that is widely distributed across the marginal seas of the northwestern Pacific. Several kinds of DNA markers, such as amplified fragment length polymorphisms (AFLP), mitochondrial DNA (mtDNA) and single nucleotide polymorphisms (SNPs), have been used to assess the population genetic characteristics of this species in previous studies. However, there have been no genetic profiling studies to cover the entire distribution. Here, six highly polymorphic microsatellite markers were applied to 18 populations across a spatially large area (from the Sea of Japan in the north to the South China Sea in the south). The results showed that the whole population exhibits high, stable genetic diversity, low relatedness and large effective population size. There was very weak genetic differentiation overall and no isolation by distance occurred among the populations, which may be attributed to significant contemporary gene flow, each generation. The above results may lead us to infer that the recent S. marmoratus population structure could be considered as one large integrated population. The present study will be beneficial to population conservation and fisheries management of S. marmoratus and will lead to better insights into the genetic characteristics of other species that belong to the Sebastidae family.

“…We suggest that boobies from Middle Cay display repeatability in foraging trips at the population level due to a relatively predictable increase in productivity formed by the underlying bathymetry of the area. Previous examinations of the hydrodynamic environment surrounding Jamaica have found sea surface velocities within the study area to be highly variable in both intensity and direction, with the formation of many mesoscale currents, eddies, and jets that are ephemeral in both space and time [41]. A notable exception is Pedro Bank, over which sea surface velocities are significantly depressed.…”

“…Supporting the most productive fisheries in the country, primarily targeting queen conch (Lobatus gigas), spiny lobster (Panularis sp. ), and finfish, Pedro Bank and associated small cays host a diverse and abundant marine community as well as a seasonally-variable yet significant human population of artisanal fishers [40,41]. With the largest human settlement on Middle Cay, interactions between nesting boobies and local fishers are likely common and widespread (A. Haynes-Sutton pers.…”

In marine environments, tropical and subtropical habitats are considered to be inherently less productive than more temperate systems. As such, foraging site fidelity among vertebrate predators occupying low-latitude marine systems is generally low as a response to an increased unpredictability of resources. We investigated the foraging movements of Masked Boobies breeding on Middle Cay, Jamaica using GPS loggers to examine if the presence of a nearby bathymetric feature influenced foraging site fidelity in a tropical system, the Caribbean Sea. According to the movements of tracked individuals, this population of boobies shows a high degree of spatial fidelity in foraging site selection, concentrated on the northern edge of Pedro Bank. We suggest this feature as an important location for marine conservation in the region and demonstrate its utility to foraging boobies via habitat modeling using a maximum entropy approach of relevant habitat variables. Finally, we place this study into the global context of Masked Booby foraging by examining the published literature of relevant tracking studies for population-level similarity in foraging metrics. According to hierarchical clustering of foraging effort, Masked Boobies demonstrate a density-dependent response to foraging effort regardless of colony origin or oceanic basin consistent with the principles of Ashmole's Halo.

“…The multi-million US dollar conch trade has declined significantly throughout the Caribbean with little known about whether it can recover. It was found that genetic connectivity of the species across the region was limited by oceanic distance [39], making recovery of specific populations difficult due to complete reliance on self-recruitment or on upstream populations in the territorial waters of neighboring countries. The management practices, or lack thereof, on upstream populations therefore have a significant impact on the recovery of downstream populations [39,40].…”

Valuing Caribbean biodiversity for health and wealth requires knowledge of the bioresource so as to better appreciate the myriad of uses and services it provides. Increasing the knowledge base provides increasingly accurate valuation, which hopefully will lead to better management and sustainable use of this biodiversity. The Caribbean region comprises 229,540 km 2 of land (only 10% of which is still in original forest cover) and 2,754,000 km 2 of ocean. In the region there are about 13,000 identified plant species of which 205 genera and 6500 species are endemic. The marine area, with a maximum depth of 7686 m, includes the world's second largest barrier reef. It is estimated that the region has 25.6% marine endemic species. Multiple uses have been found for both terrestrial and marine organisms of the Caribbean. Mass extinctions have occurred for Peoples, associated traditional knowledge, terrestrial and marine biodiversity. Sea level rise and increasing temperature are global problems that threaten this area. All this information cannot be covered in one chapter so this review, based on a wide range of publications including our own research, is to raise awareness of these issues and the need to know more while suggesting solutions for discussion.
