Bonus Monarchs

Tens of thousands of migrating monarch butterflies are stuck in northern climes this autumn because of unusually warm weather and strong winds that have grounded them.

Biologist Elizabeth Howard, director of the monarch tracking group Journey North, says the colorful insects have been seen from far southern Ontario to near Cape May, New Jersey. Monarchs typically arrive in their central Mexican winter home about Nov. 1.

Howard points out that many of the stragglers are a sort of “bonus generation” that was able to emerge late in the season because of the delayed chill.

Salmon Crisis

Not a single wild salmon returned to a key breeding river in New Brunswick, Canada, to spawn for the first time on record.

“It means for the Magaguadavic River, whatever wild salmon that existed there are now extinct,” said Neville Crabbe, spokesman for the Atlantic Salmon Federation.

The federation says the decline in the once-abundant wild salmon from Atlantic Canada to Maine is partly due to an increase in salmon farming in the region.

Other factors include the construction of dams, loss of habitat, pollution, climate change and overfishi
