A local medical doctor, a marine ecologist, and oyster farmers are raising an alarm that a nearby monoculture plantation of Eucalyptus nitens may be poisoning local water reserves, leading to rare cancers and high oyster mortality in Tasmania. However, the toxin is not from pesticides, as originally expected, but appears to originate from the trees themselves. “The toxin is actually coming from the monoculture trees,” Scammell said on Australian news show, Today.
A surprising new study finds that during the past century the frequency of fog along California’s coast has declined by approximately three hours a day. Published in the Proceedings of the National Academy of Sciences the researchers are concerned that this decrease in fog threatens California’s giant redwoods and the unique ecosystem they inhabit. “As fog decreases, the mature redwoods along the coast are not likely to die outright, but there may be less recruitment of new trees; they will look elsewhere for water, high humidity and cooler temperatures,” explains coauthor Todd E. Dawson, professor of integrative biology and University of California, Berkeley professor of integrative biology with the Department of Environmental Science, Policy and Management (ESPM).
