Hawksbill sea turtles: can phylogenetics inform harvesting?
In their recent articles, Mortimer et al. (2007) and Bowen et al. (2007) imply that historical declines in hawksbill sea turtle (Eretmochelys imbricata) populations in the Caribbean together with new phylogenetic data provide solid evidence that hawksbills cannot be harvested on a sustainable level. We suggest that broad inferences on the impacts of harvesting based on phylogenetic data alone a...
متن کاملNatal foraging philopatry in eastern Pacific hawksbill turtles
The complex processes involved with animal migration have long been a subject of biological interest, and broad-scale movement patterns of many marine turtle populations still remain unresolved. While it is widely accepted that once marine turtles reach sexual maturity they home to natal areas for nesting or reproduction, the role of philopatry to natal areas during other life stages has receiv...
متن کاملConservation of Hawksbill Sea Turtles: Perceptions and Realities
sea turtle species survive in only a limited area of its natural range. Sea turtles must occur throughout their natural ranges to ensure that they fulfill their ecological roles. For example, hawksbills are primary predators in coral reef ecosystems and thus assist in maintaining the biodiversity and ecological processes of these complex ecosystems. Unfortunately, as is made all too clear in th...
متن کاملImpact of coral predators on tropical reefs
It is well known that herbivores have numerous and diverse impacts on plant and algal fitness, community structure and ecosystem function. The importance of corallivory as a selective force, however, has been underestimated. Corallivores, or consumers of live coral tissue, employ a wide variety of feeding strategies and can be obligate or facultative coral feeders. Our literature review reveals...
متن کاملDeforestation: risk of sex ratio distortion in hawksbill sea turtles.
Phenotypic sex in sea turtles is determined by nest incubation temperatures, with warmer temperatures producing females and cooler temperatures producing males. The common finding of highly skewed female-biased hatchling sex ratios in sea turtle populations could have serious repercussions for the long-term survival of these species and prompted us to examine the thermal profile of a relatively...
