This poster summarizes the key features of the seagrass communites in the Bocas del Toro archipelago, Panama. Seagrass meadows within this region are strongly influenced by their proximity to coral reefs, mangrove forests and coastal rivers. Reef, mangrove and river inputs influence sediment type and water clarity, two very important factors affecting the occurrence and abundance of seagrass meadows.

This poster presents data from the lagoons along the Caribbean coast of the Yucatan Peninsula, Mexico, a region undergoing appreciable growth. The region is characterized by karst limestone without appreciable surface drainage or rivers. However, there are various submarine springs and fissures that deliver runoff to coastal waters. The tropical seagrass Thalassia testudinum was sampled near the developed regions of Cancun as well as in the Puerto Morelos lagoon to the south.
