Pathogens compromise reproduction and induce melanization in Caribbean sea fans
The fungal pathogen Aspergillus sydowii is causing high mortality of sea fan gorgonians Gorgonia ventalina in a Caribbean-wide outbreak. Fungal infection induces a localized band of melanin adjacent to fungal hyphae. We also detected an unidentified parasite that induced a similar melanin band, suggesting that melanization is a generalized response to infection. Although a common mechanism of a...
متن کاملReproduction and recruitment of corals: comparisons among the Caribbean, the Tropical Pacific, and the Red Sea*
Detailed reproductive data are now available for 210 of the ca 600 identified scleractinian reef coral species. The majonty (131 species) are hermaphroditic broadcast spawners, although hermaphroditic brooders (1 1 species), gonochoristic broadcasters (37 species), and gonochoristic brooders (7 species) have also been reported. Characteristics of sexuality and mode of reproduction are generally...
متن کاملBoxer crabs induce asexual reproduction of their associated sea anemones by splitting and intraspecific theft
Crabs of the genus Lybia have the remarkable habit of holding a sea anemone in each of their claws. This partnership appears to be obligate, at least on the part of the crab. The present study focuses on Lybia leptochelis from the Red Sea holding anemones of the genus Alicia (family Aliciidae). These anemones have not been found free living, only in association with L. leptochelis. In an attemp...
متن کاملCirculation of the Caribbean Sea
The geostrophic method was applied to six north-south hydrographic profiles across the Caribbean Sea and one across the Yucatan Strait. An axis of flow exists in the southern third of the Caribbean Sea. It flows directly over the steep slope in the reference layer found by Defant's method. This condition is similar to that of the Gulf Stream. The baroclinic mass distribution extends to approxim...
متن کاملCan myxosporean parasites compromise fish and amphibian reproduction?
Research into fish and amphibian reproduction has increased exponentially in recent years owing to the expansion of the aquaculture industry, the need to recover fishery populations, the impact of endocrine disruptors on the aquatic environment and the global decline of amphibian populations. This review focuses on a group of parasites, the Myxozoa, that affect fish and amphibian reproduction. ...
