Readings

For this week we read a meta-analysis by Graham and Nash (2013) that addressed the importance of structural complexity on coral reefs.

Graham NAJ, Nash KL. 2013 . The importance of strucutre complexity in coral reef ecosystems. Coral Reefs 32: 315-326.

Three additional papers are posted to the right, which will be presented during the introductory lecture (or next week...as time allows).



Coral Reef Introduction

Class 1: Distributions of corals and coral reefs

                or:   What’s so special about the coral triangle?

                or:   Should we care about crappy (marginal; peripheral) reefs?

Main points:

(1)    Corals require light (shallow, clear), warm water, oligotrophic (sometimes), hard substrate, full salinity.

(2)    Main center of biodiversity in “coral triangle” of Indo West Pacific with secondary centers in the Red Sea and Caribbean.

(3)    Conservation issues: protecting diversity centers vs. protecting endemics, which might be in peripheral areas

(4)    Coral diversity and development can be decoupled from reef growth and development
