EAST LANSING, Mich. — Warmer oceans in the future could significantly alter populations of phytoplankton, tiny organisms that could have a major impact on climate change.
In the current issue of Science Express, Michigan State University researchers show that by the end of the 21st century, warmer oceans will cause populations of these marine microorganisms to thrive near the poles and may shrink in equatorial waters. Since phytoplankton play a key role in the food chain and the world’s cycles of carbon, nitrogen, phosphorous and other elements, a drastic drop could have measurable consequences. (more…)

EAST LANSING, Mich. — While Asian carp, gypsy moths and zebra mussels hog invasive-species headlines, many invisible invaders are altering ecosystems and flourishing outside of the limelight.
A study by Elena Litchman, Michigan State University associate professor of ecology, sheds light on why invasive microbial invaders shouldn’t be overlooked or underestimated.
“Invasive microbes have many of the same traits as their larger, ‘macro’ counterparts and have the potential to significantly impact terrestrial and aquatic ecosystems,” said Litchman, whose research appears in the December issue of Ecology Letters. “Global change can exacerbate microbial invasions, so they will likely increase in the future.”(more…)
