Chemical mediation of coral larval settlement by crustose coralline algae
The majority of marine invertebrates produce dispersive larvae which, in order to complete their life cycles, must attach and metamorphose into benthic forms. This process, collectively referred to as settlement, is often guided by habitat-specific cues. While the sources of such cues are well known, the links between their biological activity, chemical identity, presence and quantification in ...
متن کاملPrimary productivity of reef-building crustose coralline algae
The primary productivity of four species of crustose coralline algae was measured as a function of depth (0–18 m) and irradiance on samples collected from and growing upon the windward coral reef at Lizard Island, northern Great Barrier Reef, Australia. Significantly higher productivities were measured in the field than in the laboratory. Maximum gross oxygen production in situ varied from 12.8...
متن کاملCoral and crustose coralline algae disease on the reefs of American Samoa
Surveys for lesions in corals were conducted at seven sites around Tutuila in June 2004 and January 2005. The objectives of the study were to document the distribution and prevalence of disease in the major genera of corals and crustose coralline algae, systematically describe gross and microscopic morphology of lesions in reef corals and determine whether there are seasonal differences in prev...
متن کاملChiharaea and Yamadaia (corallinales, Rhodophyta) Represent Reduced and Recently Derived Articulated Coralline Morphologies(1).
Phycologists have hypothesized that the diminutive fronds produced by species in the genera Chiharaea and Yamadaia, which are composed of comparatively few genicula and intergenicula, represent morphological intermediates in the evolution of articulated corallines from crustose ancestors. We test this "intermediate frond hypothesis" by comparing rbcL sequences from the generitype species Chihar...
متن کاملCrustose coralline algae increased framework and diversity on ancient coral reefs
Crustose coralline algae (CCA) are key producers of carbonate sediment on reefs today. Despite their importance in modern reef ecosystems, the long-term relationship of CCA with reef development has not been quantitatively assessed in the fossil record. This study includes data from 128 Cenozoic coral reefs collected from the Paleobiology Database, the Paleoreefs Database, as well as the origin...
