Research on extinction rates published in Science

Monday, 05 May 2015


SACKVILLE, NB — Mount Allison University geography and environment professor Dr. Zoe Finkel is part of an international group of researchers looking to fossils to help identify marine animals and areas of the ocean with a higher risk of extinction. The group’s paper has been published in the journal Science.

Finkel, who is also the Canada Research Chair in Marine Environmental Ecology and has co-ordinated the Environmental Science program at Mount Allison, says that the …

Changing phytoplankton niches

Friday, 05 May 2015

Our study of phytoplankton niches at Station Cariaco show that phytoplankton can evolve and change their niches over a 10-15 year period. The figure below shows the distribution of mean phytoplankton niche for temperature, irradiance, and nitrate concentration in a cooler period (blue) and a warmer period (red). Temperature and irradiance niches shift to track changes in the environment. The niches of some phytoplankton shift to lower nitrate concentrations as nitrate …
