Genetic differences of Acropora palmata populations of the Mexican Atlantic

چکیده
The populations of Acropora palmata have decreased over the last four decades, and although there are several studies on their genetic diversity in Caribbean, no been published about reefs from southern Gulf Mexico. This research aimed to determine, using five microsatellite markers, variation three A. Mexican Atlantic located southwest Mexico, Campeche Bank, Caribbean. mean richness (Ng/N) studied was 0.583; lowest estimated value corresponded Bank reef. A low registered (reef He = 0.315 ± 0.052). significant structure observed among could be related ocean currents region specific biological characteristics, mainly, short larvae phase, high mortality, rate self-recruitment. These results may particularly useful for designing management strategies, considering lack this type region.

Regionally isolated populations of an imperiled Caribbean coral, Acropora palmata.
The movements of larvae between marine populations are difficult to follow directly and have been the subject of much controversy, especially in the Caribbean. The debate centres on the degree to which populations are demographically open, such that depleted populations can be replenished by recruitment from distant healthy populations, or demographically closed and thus in need of local manage...
متن کاملAssessment of Acropora palmata in the Mesoamerican Reef System
The once-dominant shallow reef-building coral Acropora palmata has suffered drastic geographical declines in the wider Caribbean from a disease epidemic that began in the late 1970s. At present there is a lack of quantitative data to determine whether this species is recovering over large spatial scales. Here, we use quantitative surveys conducted in 107 shallow-water reef sites between 2010 an...
متن کاملGenetic seascape of the threatened Caribbean elkhorn coral, Acropora palmata, on the Puerto Rico Shelf.
It has been proposed that the elkhorn coral, Acropora palmata, is genetically separated into two distinct provinces in the Caribbean, an Eastern and a Western population admixing in western Puerto Rico and around the Mona Passage. In this study, the genetic structure of A. palmata sampled at 11 Puerto Rican localities and localities from Curaçao, the Bahamas and Guadeloupe were examined. Analys...
متن کاملGenetic Susceptibility, Colony Size, and Water Temperature Drive White-Pox Disease on the Coral Acropora palmata
Outbreaks of coral diseases are one of the greatest threats to reef corals in the Caribbean, yet the mechanisms that lead to coral diseases are still largely unknown. Here we examined the spatial-temporal dynamics of white-pox disease on Acropora palmata coral colonies of known genotypes. We took a Bayesian approach, using Integrated Nested Laplace Approximation algorithms, to examine which cov...
