As if humpbacks were not astounding enough…

As if humpbacks were not astounding enough, a small subset have learned to break their solitary habits and form cooperative bubble net feeding groups with distinct specialities. The screamer calls the cadence and petrified the herring with a high pitch squeal that causes them to ball up. Then fin flappers flash the white underside of their pectorals to add a bewildering stimulus while a bubble blower ascends from below creating a rising spiral of expanding effervescent gas that forms a net to contract the fearful fish. Then altogether these unrelated whales rise and engulf in their huge maws the school of fish taking up to 16,000gallons in a single gulp and straining the contents back across their baleen. Not only does this suggest these animals have culture but also that they are tool users not so unlike ourselves!

Straight from the reels of Jumanji…

Straight from the reels of Jumanji (but shrunk considerably, thank heavens) this carnivorous Sun Dew makes up for the fact that it can't get nutrients from the acid rich peat bog by trapping and eating insects! Peat bogs locally called "Muskeg" make up some 10% of Southeast Alaska and form in a process called "paludification" when sphagnum moss colonize the dense forests. Sphagnum acidifies the soil and attracts more water which leaches out the minerals till they sink below and form a hard pan that traps more water, collects more acid, which grows more sphagnum until a bog with its hardy bog plants replace the forests. Bizarrely this often happens even on slopes. Only the churning of soil by trees falling seems to be able to stop it!

At Home Realities

I hope that we’ll take what we saw in Rio as a reminder of our own domestic environmental policies and regulatory failures. I hope we’ll continue to work to do better. I hope the kind of activism and determination that culminated in the Clean Water Act will carry into the future, uplifted on a new generation committed to local, regional, and national activism.
