Última An unusual new gorgonian coral (Anthozoa: Octocorallia) from the Aleutian Islands, Alaska Naturalis Sánchez, J.A.; Cairns, S.D.. Despite the abundance and ecological importance of octocorals in Alaskan waters, most of the species in this assemblage remain unidentified and/or undescribed. One of the largest and most abundant species from the Aleutian Islands found at depths ranging between 125 and 512 m is a new and very unusual gorgonian coral. It has stout upright colonies that are laterally branched, with thick, more or less clavate terminal branches. Its major distinguishing characteristic is its possession of tiny sclerites with stubby double heads, which occur in the outermost coenenchyme. Another significant character is its oval capstans with elaborate ornamentation. The gorgonian is described as Alaskagorgia aleutiana new genus and species (Cnidaria: Octocorallia: Holaxonia:...

Ano: 2004 URL: http://www.repository.naturalis.nl/record/214439 Annual skeletal extension of two reef-building corals from the Colombian Caribbean Sea OceanDocs Charry, H.; Alvarado, E.M.; Sánchez, J.A.. The skeletal growth of the scleractinian corals Diploria labyrinthiformis (Linnaeus 1758) and Montastraea annularis (Ellis and Solander 1786) from Isla Grande (north of Rosario islands), Colombian Caribbean, was determined from annual extension increments revealed by X-radiography of 4-6 mm thick slabs obtained along the axis of maximum growth. The skeletal extension average rate for the last 22 years for D. labyrinthiformis was 3.8 mm year-1 (SE 0.10; N = 87). The correlation between growth of D. labyrinthiformi s and hours of sunlight was significantly negative. The annual variances of sunlight enhanced annual statistically significant differences of growth in this species. M. annularis showed an average extension growth of 10.6 mm year-1 (SE 0.32; N =...
