The Amazon is evolving, but not adapting as fast the climate is changing

Science
Nov. 8 (UPI) -- According to a new survey of the Amazon, the planet's largest forest is shifting its composition in response to climate change. Unfortunately, the research suggests the Amazon isn't evolving fast enough. The climate is changing faster than the Amazon can adapt. Most noticeably, scientists found moisture-loving tree species are dying off faster than they can be replaced by species that can withstand drier conditions. Droughts during the last decades have damaged large portions of the Amazon. "The ecosystem's response is lagging behind the rate of climate change," Adriane Esquivel Muelbert, geographer at the University of Leeds, said in a news release. "The data showed us that the droughts that hit the Amazon basin in the last decades had serious consequences for the makeup ...
Here to stay, sea pickles are adapting comfortably to Pacific Northwest waters

Here to stay, sea pickles are adapting comfortably to Pacific Northwest waters

Science
July 20 (UPI) -- Sea pickles have been invading the waters along the coast of the Pacific Northwest for a few years. Now, new research suggests the cucumber-shaped colonial jellies, called pyrosomes, are here to stay. The pickles are bioluminescent -- pyrosome translates as "fire body." Each tube-like creature is actually many creatures, a colony of multi-celled organisms call zooids. "These animals may be able to survive in colder water than we previously thought possible, but what might really be contributing to their continued presence is that the food source off of our coast is right for them," Kelly Sutherland, a marine biologist at the University of Oregon, said in a news release. Sutherland and her researcher partners believe the lack of upwelling in the ocean has made for pickle-...
