Our knowledge of the various modes of sexual reproduction in stony corals has increased greatly during the last two decades, but is far from encompassing the wide variety of reproductive strategies exhibited by this group. Here, for the first time in stony corals, I report on sex change exhibited by two mushroom corals, Fungia repanda and Ctenactis echinata in Okinawa, Japan.
Sex change in animals has been reported as occurring from M-F (male to female i.e., protandry) and vice versa i.e., F-M (protogyny), but in a few cases also as bidirectional. While F. repanda exhibited protandry only, C. echinata revealed a repetitive mode of sex change, which greatly resembles that of dioecious plants that display labile sexuality in response to energetic and/or environmental constraints. I posit that, similar to these plants, in the studied corals sex change increases their overall fitness, reinforcing the important role of reproductive plasticity in scleractinian corals in determining their evolutionary success.
James Cook University researchers have found brightly coloured fish are becoming increasingly rare as coral declines, with the phenomenon likely to get worse in the future. Christopher Hemingson, a
Researchers working with stakeholders in the Great Barrier Reef region have come up with ideas on how groups responsible for looking after the reef can operate more effectively when the next bleaching
A new study has delivered a stark warning about the impacts of urban growth on the world’s coral reefs. As coastal developments expand at pace around the world, a year-long study of coral on a reef
Alarming new research shows global warming of 1.5°C relative to pre-industrial levels will be catastrophic for almost all coral reefs – including those once thought of as refuges. Associate Profes
Abstract: Evolution of many eukaryotic organisms is affected by interactions with microbes. Microbial symbioses can ultimately reflect host’s diet, habitat range, and even body shape. However, how
