Importance of Photosynthetic Symbionts in Sponges

Data was collected on the biogeography and biodiversity of photosynthetic symbionts of marine sponges in Australia. From 2000, sponges from around Australia were sampled using a Diving PAM (pulse-amplitude modulation), molecular analyses and classical taxonomy to quantify the abundance of photosynthetic symbionts in sponges, particularly in temperate Western Australian waters.
