When the ocean heats up, urchin love life cools down. New Hakai-linked study shows that even modest, non-lethal warming can suppress purple sea urchin reproduction — a twist that could temporarily help kelp forests recover. But both kelp and urchins feel the heat.

What did Vancouver Island’s forests look like after the last ice age?
New research from northern Vancouver Island shows forests didn’t all respond the same way as the climate warmed—each landscape told its own story.
