Climate surprise: Warming planet helps Florida mangroves conquer oysters
(Sun-Sentinel Miami Dolphins Blog)

Within the Mosquito Lagoon refuge of tiny islands and sea water saltier than the ocean is a battle of natural Florida`s titans. The lagoon`s reigning guardians are oysters. The invaders are mangroves. Scientists think mangroves may be winning, thanks to a new ally in the rising level of carbon dioxide in the atmosphere, trapping more of the sun`s heat and rapidly warming the planet. Mangroves are aggressive but can`t tolerate freezing weather and they haven`t had to lately. Cold snaps have all but vanished in the past couple of decades in the Mosquito Lagoon.
