Fish alter migration patterns as global waters warm

Water spills from the edge of a giant, melting iceberg on the cover of the November 2015 issue of Science.

The special issue focused on the effects of climate change on our ocean systems, and highlighted research by Dr. William Cheung, an Associate Professor with the Changing Ocean Research Unit at the University of British Columbia, and Director (Science) of the Nereus Program. The journal used a map Dr. Cheung and his team created that describes the effects of changing water temperatures on fish species migration.

Warming Oceans and Rising Tides: Coastal Adaptation in Northwest BC, Canada

Vicky Lam, Fisheries Economist and Senior Research Fellow (UBC), was invited by the Fraser Basin Council to give a presentation on the impacts of climate change on fisheries on the coast of northwest British Columbia, Canada. She attended the one day workshop titled “Warming Oceans and Rising Tides: Coastal Adaptation in Northwest BC”, in Prince Rupert on October 21.

Are we adapting to climate change, or resigning to it?

by Andrés M. Cisneros-Montemayor

In A Sand County Almanac, the landmark book on wilderness, ecology, and conservation, we are offered a short anecdote regarding a changing environment:

“I had a bird dog named Gus. When Gus couldn’t find pheasants he worked up an enthusiasm for Sora rails and meadowlarks. This whipped-up zeal for unsatisfactory substitutes masked his failure to find the real thing. It assuaged his inner frustration.” – Aldo Leopold (1949).

William Cheung and Gabriel Reygondeau publish chapter on The Southern Ocean in the Ocean and Climate Platform’s Scientific Notes

William Cheung, Director of the Nereus Program (Science), and Gabriel Reygondeau, Nereus Fellow (UBC), are co-authors of a chapter on The Southern Ocean, published in the Ocean and Climate Platform’s Scientific Notes. The Ocean and Climate Platform is an alliance of NGOs and research institutes, with support from UNESCO.

“Climate Change Shifting Fish Reproduction Timing In Southern California Current”, published in FishSens magazine, highlights a study by Rebecca Asch, Nereus Fellow at Princeton University, on the effects of climate change and natural variability on fish reproduction.

Ask an Expert: How will this year’s El Nino affect oceans and fisheries?

Godzilla. Bruce Lee. The names for this year’s El Nino are growing, as are the fears that this might be the biggest one yet. But what is an El Nino and what effects do they have on oceans and fisheries?

Ryan Rykaczewski, Nereus Program alumni and assistant professor at the University of South Carolina, focuses his research on the responses of ecosystem and fisheries production to past and future climate variability and climate change and has published on the impacts of past El Ninos. Here he explains the basics of El Ninos and why this upcoming one could have destructive impacts on ocean ecosystems, fisheries, and fish and mammal species.

Daniel Pauly and William Cheung published on long term management of threats to the polar regions

Daniel Pauly, Chair of the Nereus Steering Committee and a member of the Advisory Board, and William Cheung, Director of the Nereus Program (Science) and Principle Investigator, have co-authored a paper titled “Polar lessons learned: long-term management based on shared threats in Arctic and Antarctic environments” in Frontiers in Ecology and the Environment. This paper looks at the threats to the Arctic and Antarctic polar regions, including climate change, pollution, fisheries overexploitation, and invasive species. The paper advises that “until the greenhouse-gas emissions that drive climate change can be reduced, it is crucial to address other threats (including pollution, fisheries overharvesting, and invasive species) that interact with climate change.”

Key lessons from the “Our Common Future under Climate Change” conference

by Mathieu Colléter, Nereus Fellow

I had the great opportunity of spending the last three weeks in France to attend two conferences: the 12th French fisheries scientists’ symposium in Montpellier, and “Our Common Future under Climate Change” scientific conference in Paris (CFCC). This was an insightful experience, and since this is my debut performance in the universe of blogging, I would like to share this by highlighting some of the main aspects of the presentations delivered in the beautiful city of Paris.
