STORM COMING DOWN

Like most mountainous areas, Bowron makes its own weather system and it appears you get everything in a 24-hour period. In fact, whatever weather you are enjoying seems to change 40 minutes later; good for rain, bad for sun. Wisps of cloud that seemed light and airy only hours early have become dark. Careful to hug the shore, we are ready for a quick escape from lightening as thundershowers break.

SLOTHS AND BLUE GREEN

Ever wonder why the slow moving sloth has a slightly greenish hue? Ever consider the sloth at all? Well, perhaps not. Location, location, location, is the mantra for many of us in our macro world, but it is also true for the small world of algae.

Blue green algae is a term used to describe any of a large, heterogeneous group of prokaryotic, principally photosynthetic organisms. These little oxygenic (oxygen-producing) fellows appeared about 2,000,000,000 to 3,000,000,000 years ago and are given credit for greatly increasing the oxygen content of the atmosphere, making possible the development of aerobic (oxygen-using) organisms.

But all this heavy breathing aside, we go back to sloths and the wonder of making do where you are. The sloth's body and shaggy coat, or pelage, provides a comfy habitat to two types of wee blue-green algae along with various other invertebrates. The hairs that make up the sloth's coat have grooves that help foster algal growth.

And, while Kermit the Frog says, "it's not easy being green," it couldn't be further from the truth for this slow-moving tree dweller. The blue-green algae gives the sloth a natural greenish camouflage, an arrangement that is certainly win-win.

WHEN THE TIDE IS OUT THE TABLE IS SET

Have you ever watched salmon jump, twist and leap their way past the many hurtles to return to their place of birth to spawn?

We are all familiar with the image of salmon returning to fresh water, to the rivers of their youth, to spawn and complete their lifecycle, in fact, it is one of the staple images of British Columbia. As adults, we bring our children to witness this cycle, rushing to the banks of our local rivers to watch as the adults, keen in their fight for reproduction and survival, struggle to complete their epic journeys against currents and predators. Arriving as they do, year upon year, season upon season, it seems to us that this is how it has been since time immemorial.

But we now have evidence that migration to the sea may be a relatively recent behaviour. Fossil beds at Driftwood Canyon, near Smithers, contain large numbers of fossil salmonid remains from the Eocene age, approximately 45 million years ago. What is interesting is that the fossil beds are filled equally with both juvenile and larger adults.

If these salmon were heading off to sea in their juvenile form and returning to spawn as adults we would expect to find an abundance of larger carcasses in the lake sediments and relatively few juveniles. Given the equal numbers, we can conclude that the salmonids of the Eocene, lived out their lifecycle as a landlocked species, the way Kokanee do today.

GRIZZLY & BLACK BEARS

Both grizzly and black bears descend from a common ancestor, Ursavus, a bear-dog the size of a raccoon who lived more than 20 million years ago. Seems an implausible lineage given the size of their large descendents.
