Old species learn new tricks...very slowly

Wed, 15 Aug 2018 17:11:09 EDT ~ No species lasts forever, and, just as the saying goes, it seems like old species may get stuck in their ways and can't adapt to environmental change as fast as younger species do. Find out more...

When viruses infect phytoplankton, it can change the clouds

Wed, 15 Aug 2018 13:05:36 EDT ~ Microscopic plant-like organisms called phytoplankton support the diversity of life in the ocean. Scientists now report that one species, Emiliania huxleyi, and a virus closely associated with it, might be responsible for changes in cloud properties as well. When infected, E. huxleyi releases its chalky shell into the air, where it acts as an aerosol reflecting sunlight and even affecting cloud creation and movement. Find out more...

Apathy towards poachers widespread in world's marine protected areas

Wed, 15 Aug 2018 10:29:18 EDT ~ A new study has found that nearly half of fishers from seven countries had witnessed someone poaching in marine protected areas in the past year and most of them did nothing about it. Find out more...

Arctic seabird populations respond to climate change

Wed, 15 Aug 2018 09:15:20 EDT ~ Seabirds such as gulls can be key indicators of environmental change as their populations respond to shifts in their ocean habitat over time. A new study investigates how several species have responded to changing environmental conditions in the Arctic over the last four decades. The authors find that a warming ocean is directly and indirectly affecting seabird populations in Alaska. Find out more...

Glacier depth affects plankton blooms off Greenland

Tue, 14 Aug 2018 10:14:38 EDT ~ The unusual timing of highly-productive summer plankton blooms off Greenland indicates a connection between increasing amounts of meltwater and nutrients in these coastal waters. Researchers now show that this connection exists, but is much more complex than widely supposed. Whether increasing meltwater has a positive or negative effect on summertime phytoplankton depends on the depth at which a glacier sits in the ocean. Find out more...

Young salmon may leap to 'oust the louse'

Mon, 13 Aug 2018 10:03:03 EDT ~ A study by aquatic ecologists reveals that young salmon may jump out of water to remove sea lice. Find out more...

Sea stars critical to kelp forest resilience

Mon, 13 Aug 2018 10:03:00 EDT ~ A study by a resource and environmental management researcher reveals that sunflower sea stars play a critical role in the resilience of B.C.'s kelp forests, which are among the most productive ecosystems on Earth. Similar to land-based forests, kelp forests provide essential habitat for species and also help remove CO2 from the atmosphere. Find out more...

Marine mammals lack functional gene to defend against popular pesticide

Thu, 09 Aug 2018 14:12:15 EDT ~ As marine mammals evolved to make water their primary habitat, they lost the ability to make a protein that defends humans and other land-dwelling mammals from the neurotoxic effects of a popular human-made pesticide. The implications of this discovery led researchers to call for monitoring our waterways to learn more about the impact of pesticides and agricultural run-off on marine mammals, such as dolphins, manatees, seals and whales.

Diverse symbionts of reef corals have endured since 'age of dinosaurs'

Thu, 09 Aug 2018 14:11:55 EDT ~ Coral-algal partnerships have endured numerous climate change events in their long history, and at least some are likely to survive modern-day global warming as well, suggests an international team of scientists. Find out more...

'Biological passport' to monitor Earth's largest fish

Thu, 09 Aug 2018 09:34:35 EDT ~ Whale sharks, the world's largest fish, roam less than previously thought. This new study used stable isotope analysis to demonstrate that whale sharks feeding at three disparate sites in the Western Indian Ocean and Arabian Gulf rarely swim more than a few hundred kilometers north or south from these areas according to researchers.
