Evolution makes invading species spread even faster
2015-04-22 12:00:00| LifeSciencesWorld
[NEWS] Today, invasive animals and plants spread all around the globe. Predicting the dynamics of these invasions is of great ecological and socioeconomical interest. Yet studying them is fundamentally challenging because of the large spatial and temporal scales involved. Scientists at Eawag and University of Zurich are now using computer simulations and small artificial laboratory worlds, to study how rapid evolution makes invaders spread even faster. Due to worldwide mobilit…

Jellyfish in the UK: Huge blooms of barrel species found on coast after mini-heatwave
2015-04-19 10:39:00| Climate Ark Climate Change & Global Warming Newsfeed
Independent: Scores of large jellyfish have been discovered on Britains coastline after they have been attracted to warmer conditions brought on by a recent mini-heatwave. Blooms of barrel jellyfish that can grow up to the size of a dustbin lid have been spotted on the south coast after a summer-like climate made a brief appearance. The species can weigh up to 55lbs (24kgs) and have eight thick arms, rather than tentacles, made from frilly-like tissue. Although the jellyfish, which have no brain...

Longest mammal migration raises questions about distinct species
2015-04-15 12:00:00| LifeSciencesWorld
[NEWS] NEWPORT, Ore. - A team of scientists from the United States and Russia has documented the longest migration of a mammal ever recorded - a round-trip trek of nearly 14,000 miles by a whale identified as a critically endangered species that raises questions about its status. The researchers used satellite-monitored tags to track three western North Pacific gray whales from their primary feeding ground off Russia's Sakhalin Island across the Pacific Ocean and down the…

io9: According to the Seattle Times, the groups that petitioned to protect the yellow cedar are pleased with the announcement, which came on Thursday. The decision is great news for the Tongass National Forest and for yellow cedar, said Rebecca Noblin, an attorney in Anchorage for the Center for Biological Diversity, one of the groups that petitioned to list the tree. Were losing yellow cedar rapidly to climate change, and if we dont start addressing our greenhouse gas emissions, were going...

30 new species discovered in Los Angeles in first-ever intensive urban biodiversity survey
2015-03-25 11:00:00| LifeSciencesWorld
[NEWS] A new paper to be published in the journal Zootaxa (April 6, 2015) describes 30 new insect species in a single genus, Megaselia, of the fly family Phoridae. Describing 30 species in a single paper is rare, but what's especially striking is that all these come from urban Los Angeles. The discoveries come from researchers in the BioSCAN project (Biodiversity Science: City and Nature) at the Natural History Museum of Los Angeles County (NHM). The BioSCAN pro…
