RESUMEN
Poribacterial clone libraries constructed for Aplysina fulva sponge specimens were analysed with respect to diversity and phylogeny. Results imply the coexistence of several, prevalently "intra-specific" poribacterial genotypes in a single sponge host, and suggest quantitative analysis as a desirable approach in studies of the diversity and distribution of poribacterial cohorts in marine sponges.

An analysis has been made of the causes of death and ages at death from the registrar of deaths on the island of Anguilla from 1885 to 1980. Prior to 1945, infant mortality was about 100 per thousand live births but subsequently started to fall and is now 30. Similarly, deaths under the age of 5 years as a percentage of total deaths was 30 percent but fell to 10 percent in 1980. Infections are now very rarely registerd as cause of death whereas stroke and cancer have become increasingly frequent.(AU)
