The excavating sponges of the Santa Marta area, Colombia, with description of a new species
Provedor de dados: 16
Autores: Hofman, Caroline C.; Kielman, Margriet.
From June till December 1987 an inventory of the excavating sponges of the Santa Marta area, Colombian Caribbean, was made by scuba diving to depths not exceeding 18 m. Sixteen species were recorded and compared morphologically, using spicule sizes, papillae shapes, and excavation characteristics. Four littleknown species are fully described and illustrated by submarine color photographs in situ. One appears to be a new species: Axinyssa flavolivescens, belonging to a genus not known to excavate so far. The other three species could not be identified with certainty: Aka äff. xamaycaensis, Aka aff. brevitubulata, and Cliona aff. flavifodina. A key to the excavating sponges of the area studied is provided.

ABUNDANCE OF THE EXCAVATING SPONGE CLIONA DELITRIX IN RELATION TO SEWAGE DISCHARGE AT SAN ANDRÉS ISLAND, SW CARIBBEAN, COLOMBIA
Provedor de dados: 50
Autores: Chaves-Fonnegra,Andia; Zea,Sven; Gómez,Martha L.
It is known that the encrusting and excavating Caribbean sponge Cliona delitrix may increase its abundance near sources of sewage. To ascertain whether its current conspicuousness in leeward reefs of San Andrés Island (SW Caribbean, Colombia) is related to organic pollution from local raw sewage discharges, quantitative data on density and cover of this sponge and other benthic components was obtained from belt and line transects at seven stations along the shallow (5-10 m deep) terrace. Coral mucus was sampled to quantify Escherichia coli bacteria, as an approximate indicator of sewage plume influence on benthic biota. A negative multiplicative regression between amount of E. coli in coral mucus and distance from the main raw sewage outlet demonstrated...
