Developing an integrated framework for studying
Halophila stipulacea, the world’s first globally invasive marine
angiosperm (Seagrass) - A Euromarine foresight workshop
The Inter University Institute (IUI), Eilat, Israel 3-5th July 2016
H. stipulacea meadows in their native habitat (the northern Red Sea)
opening of
Suez 1869
Lessepsian migrant
1st record in Med: Rhodes (Fritsch 1895)
Since 1894 Spreading only in eastern Med:
Likpin 1975, Gambi et al. 2009, Sghaier et al. 2011winter surface isotherms (November -April)
limited by cold waters ?
Since 2003, reported in western Med: Sicily, Southwest Italy, Tunis
1st record of viable pods in Med (Aug 2012)
Gerakaris and Tsiamis (2015)
H. stipulacea meadows in their invasive native habitat (Caribbean)
2002: H. stipulacea found 1st time in the Caribbean, island of Granada

Mediterranean becoming warmer and saltier
Could European seagrass species (P. oceanica, Z. marina)
be replaced by the invasive H. stipulacea ?
Should Europe worry ?
?
Highlights and main topics discussed at the workshop
H. stipulacea in its native habitat
Bio invasions: What makes a successful invader?
The invasion of H. stipulacea into the Mediterranean
The invasion of H. stipulacea into the Caribbean
Developing molecular tools for H. stipulacea
Predictions for the future: Developing climate envelope distribution models
How to predict the future distribution and impacts of H. stipulacea ?
1. Produce a review paper:
The invasive tropical seagrass Halophila stipulacea –
identifying the gaps of knowledge (in progress)
2. Develop Framework for European proposals:
a) Predicting ability of H. stipulacea to invade European coastal waters
b) Assessing its impacts on both biodiversity and ecosystem functions.
