Effects of anthropogenic stressors on tropical sponge ecology

The impacts of coastal development, ocean acidification, and temperature increases on sponge ecology were investigated, with an emphasis on community-wide impacts. At three locations with varying degrees of coastal development and sediment supply, field surveys were used to assess existing sponge abundance, diversity, species richness and community composition in Jamaica. 469 kata lagi
