Sponge distribution and the presence of photosymbionts in Moorea, French Polynesia
Photosymbionts play an important role in the ecology and evolution of diverse host species within the marine environment. Although sponge-photosymbiont interactions have been well described from geographically disparate sites worldwide, our understanding of these interactions from shallow water systems within French Polynesia is limited. We surveyed diverse habitats around the north coast of Mo...
متن کاملHabitat Distribution and Comparison of Brittle Star (Echinodermata: Ophiuroidea) Arm Regeneration on Moorea, French Polynesia
Autotomy and regeneration are widespread in many groups of invertebrates and vertebrates, such as annelids, crustaceans, amphibians, and reptiles. Regeneration is common in all classes of Echinodermata and prevalent in ophiuroid brittle stars. Moorea, French Polynesia was surveyed for species of brittle stars living on coastal areas of the island in different habitats. Ophiuroid populations wer...

Ingestion and transformation of algal turf by Echinometra mathaei on Tiahura fringing reef (French Polynesia).
The sea urchin Echinometra mathaei is the most abundant herbivore on many tropical reefs. We studied the ingestion and digestion diel rhythms, transformation of algal turf and bioerosion attributable to this species on the Tiahura fringing reef in French Polynesia. Ingestion rates showed a circadian rhythm with most feeding taking place during the night. Absorption of food occurred throughout t...
متن کاملThe potential for self-seeding by the coral Pocillopora spp. in Moorea, French Polynesia
Coral reefs in Moorea, French Polynesia, suffered catastrophic coral mortality through predation by Acanthaster planci from 2006 to 2010, and Cyclone Oli in 2010, yet by 2015 some coral populations were approaching pre-disturbance sizes. Using long-term study plots, we quantified population dynamics of spawning Pocillopora spp. along the north shore of Moorea between 2010 and 2014, and consider...
