El Niño Effects on the Dynamics and Control of an Island Ecosystem in the Gulf of California

  author={Gary A. Polis and Stephen D. Hurd and Carlos T. Jackson and Francisco S{\'a}nchez Pi{\~n}ero},
The tremendous increase in precipitation associated with the 1992–1993 El Niño profoundly affected terrestrial communities on arid islands in the Midriff region of the Gulf of California. In 1992, winter precipitation was 5.4 times the historical mean, and winter precipitation over the entire El Niño was the highest two-year amount ever recorded. Increased precipitation led to an explosion of annual plant growth on the previously barren (0–4% cover) islands: plant cover increased 10–160 times… CONTINUE READING
