Future warming, of course, depends in part on how much humanity manages to curb greenhouse gas emissions. But even under the most optimistic projections, by 2100 more than half the of U.S. national park lands are expected to heat up by at least 3.5 degrees Fahrenheit — exacerbating problems like bark beetle outbreaks, increased wildfire and the loss of unique habitat critical to some species’ survival. Under gloomier scenarios, nearly 100 percent of the country, including its parks, would see that much warming.

From the South China Morning Post:

Had somebody else picked up the phone, the story would likely have ended there, but she got through to Freeling, a dogged investi­gator and passionate conservationist. Although poachers were not in the habit of sending shellfish in unrefrigerated boxes through the post, Freeling contacted United States Customs and Border Protection, who seized and X-rayed the boxes. What they discovered confounded everyone.

A plant injured on one leaf by a nibbling insect can alert its other leaves to begin anticipatory defense responses. Working in the model plant Arabidopsis, Toyota et al. show that this systemic signal begins with the release of glutamate, which is perceived by glutamate receptor–like ion channels (see the Perspective by Muday and Brown-Harding). The ion channels then set off a cascade of changes in calcium ion concentration that propagate through the phloem vasculature and through intercellular channels called plasmodesmata. This glutamate-based long-distance signaling is rapid: Within minutes, an undamaged leaf can respond to the fate of a distant leaf.

Now, Calflora is a database of hundreds of thousands of individual observations of plants growing in California, most of them linked to photos, and searchable by name, location, ecological community, or plant type. Most Calflora users will never get past the search function. (We use it regularly at ReWild.)

But those hundreds of thousands of observations came from somewhere, and that includes avid amateur botanizers who spied plants growing across the state, identified them, and added their observations to the Calflora database.
