Abstract : Nearly forty per cent (40%) of the world population live and depend on coastal
ecosystems for their economic prosperity. In the tropics, coral reefs, sea grass
meadows and mangroves offer essential ecological (protection, habitat, diversity,
air and water quality), economic (fisheries, coastal protection, tourism), social
(recreation) and cultural (heritage, identity) services that are essential for the
development and wellbeing of local and foreign inhabitants. Only in the
Caribbean Sea, the tourism industry in coral reef environments represents
around $8.9US billion/year and employs around 350K people. Indeed, without
coral reefs many of the coastal cities around the world would have disappear due
to hurricanes or coastal erosion. However, scientific studies show that marine
environments, and in particular coral reefs, have suffered severe transformations
in structure and function since 1980’s. Most of the ecological (and some
geological) records show that those changes may be due to natural, anthropic,
global, regional or local factors. And in some cases, the origin of their
transformation is due to a combination of factors (synergic effects).
To understand the causes that generate those community shifts, and the different
local, regional and latitudinal responses to stressors has been the basic of my
research. I will present results from expeditions done in Vietnam, Panama
(Pacific and Caribbean), Colombia, Italy and UK, as well as experiments in
laboratory with organisms from the Caribbean Sea, Mediterranean Sea, Indo-
Pacific and Tropical Eastern Pacific.
I will show how different and complementary approaches to my questions
(taxonomy, population ecology, community ecology, in-situ experiments, ex-situ
experiments, GIS tools, genetic tools, inter-institutional participation, socio-
economic approaches, national vs international efforts, etc) may support the
basis to understand and estimate community shits in tropical coral reefs, and
how those responses may help us to identify mitigation measures to preserve
marine biological diversity and support local government strategies for social
adaptation to environmental change. Some of the interesting results include
modification of ecological models developed in 1970’s and 1990’s for tropical
coral reefs, and the recent creation of a socio-economic model developed with
local communities for Community Based Sustainable Management of marine
resources.
