Atlantic Walrus and Eastern Migratory Caribou are at risk of extinction. So concluded the Committee on the Status of Endangered Wildlife in Canada (COSEWIC), which met recently in Whitehorse. The number of Canadian northern wildlife species considered to be at risk now stands at 62. Details here.

Do Marine Reserves Provide a Buffer Against the Ravages of Climate Change? Yes, say experts!

by Larry Powell

An international team of scientists is calling for more marine reserves as a way to lessen the impact of manmade climate change. 

The researchers believe, even if greenhouse gases are reduced in order to meet targets set out in the Paris Climate Accord, life on Earth will still face “serious stress and damage.” So more still needs to be done.

Marine reserves are areas of ocean where fishing and development are declared illegal. They’ve been shown to result in greater biodiversity, density, mass and size among fish and other marine life living there. Yet only a very small percentage of the world’s oceans have been set aside for this purpose.

The team suggests, well-managed marine reserves would help people adapt to “five prominent impacts” of climate change. These are; ocean acidification, sea-level rise, worsening storms, the distribution of marine life and decreased productivity and availability of oxygen. The scientists call marine reserves “a viable low-tech, cost-effective adaptation strategy that would improve the outlook, both locally and globally for the environment and people into the future.”   

A dozen scientists from several countries were involved in the study. Their findings were published recently in the proceedings of the prestigious National Academy of Sciences in the U.S.

Song diversity hints at thrushes' evolutionary past

The Hermit Thrush is famous for its melodiously undulating song, but we know very little about whether its songs vary across the large swath of North America that it calls home in the summer. A new study from "The Auk" provides the first thorough overview of geographic variation in Hermit Thrush song structure and hints at how isolation and adaptation shape differences in the tunes of a learned song within a species.
