Selective feeding in the hawksbill turtle, an important predator in coral reef ecosystems
We evaluated selective feeding in hawksbill turtles Eretmochelys imbricata by comparing ingested prey species with their availability at 2 sites in the SW Dominican Republic. Hawksbills fed on 6 benthic species: 5 demosponges (Chondrilla nucula, Geodia neptuni, Myriastra kalitetilla, Spirastrella coccinea, and Tethya crypta) and 1 corallimorpharian (Ricordea florida). Hawksbills showed positive...
متن کاملHawksbill sea turtles in seagrass pastures: success in a peripheral habitat
Hawksbill sea turtles, Eretmochelys imbricata, are closely associated with coral reef and other hard-bottom habitats. Seagrass pastures are peripheral habitats for Caribbean hawksbills. With the decline in quality and quantity of coral reefs, seagrass habitats may become more important for hawksbills. We use data from a 30-year mark-recapture study of hawksbills and green turtles, Chelonia myda...
متن کاملSelection of nesting habitat of hawksbill turtle (Eretmochelys imbricata) in two coral islands of Qeshm and Hengam in the Persian Gulf, Iran
The Persian Gulf islands are the nesting regions for the severely endangered hawksbill turtle (Eretmochelys imbricata) species. Therefore, the selection of the nesting habitat of this species in the two islands of Qeshm and Hengam was studied by a five-member working group in the spring of 2013 - 2015. Ultimately, 23 and 17 nests were identified in the south of Qeshm Island and in the south and...
متن کاملIncrease in hawksbill sea turtle Eretmochelys imbricata nesting in Barbados, West Indies
Nesting by hawksbill sea turtles Eretmochelys imbricata in Barbados, West Indies, has been monitored since 1992. Data from the index beach indicate that the number of nests may have increased as much as 8-fold over this period. The estimated abundance of nesting females on Barbados is 1250, suggesting that this eastern Caribbean island now hosts one of the largest rookeries in the wider Caribbe...
متن کاملDigital Reef Rugosity Estimates Coral Reef Habitat Complexity
Ecological habitats with greater structural complexity contain more species due to increased niche diversity. This is especially apparent on coral reefs where individual coral colonies aggregate to give a reef its morphology, species zonation, and three dimensionality. Structural complexity is classically measured with a reef rugosity index, which is the ratio of a straight line transect to the...
