The "Sunshine" Coast


Dianne and I arrived up in Alaska a few days ago, after two weeks with Justin and Shannon in British Colombia. It was absolutely beautiful there, despite rather dismal weather (Sunshine Coast? I think not.) It did put a damper on our fieldwork. Here are a few highlights from the trip:

We hiked the Skookumchuck Narrows trail, in Egmont. The hike was a bit longer than any of us expected, mostly because none of us could convert from kilometers to miles. We had both sunshine and rain, and more notably hail. It wasn’t exactly golf ball-sized, but it did make us run back under the trees for shelter. Only a few moments later, we saw a rainbow. We even caught a glimpse of a sea lion in the inlet, but I think our oohs and ahhs scared him off.

Our trip was early in the season, and many of the lakes we went into didn’t have a lot of stickleback activity. On one of our rare nice days, we went out to Ambrose Lake. It was secluded, and there was a short hike in. We got the lab’s first collection of fish from this lake. I unfortunately lost one of my fins in the water, and Justin bravely swam to retrieve it for me.

Justin and Shannon spent a few days observing fry behavior in Garden Bay Lake. Dianne and I went in search of female stickleback for observations in Hotel Lake. Unfortunately, there was not a stickleback to be found! We’re hoping to see more activity when we return to BC in a week, with Susan and Josh.

Being a Tale of Success



A successful day for Team Animal Behavior! This was especially exciting after a washout yesterday. Our primary objective was to dive in Willow Lake to gather courting and parental males and observe color patterns on them. But with the wind and clouds yesterday, no such luck, and we were forced to return early and wait for better weather.

Today, however...today was sunny and warm, just the sort of weather needed for this work. It was an early start for us in order to get to Willow Lake at a decent hour. Once there, Susan and Dianne suited up while Lily prepared the equipment in the rear of the car. For the next three hours Susan and Dianne patrolled the shallows for males, and Lily and I performed the tests on the fish, which culminated in dropping them in antacids and stringing them up with needle and thread. Those three hours alternated between Susan and Dianne catching more fish than we knew what to do with and us waiting for more fish to be caught, which left time to enjoy the sun on the lakeside.


A future trip would be nice, considering most of the eggs had just been laid. However, I'd still count this as a win, based on how yesterday went!

The next stop was a brief trip to South Rolly Lake in search of pike. The hopes were to confirm that pike were in the lake so that the lake could be used for future research projects. Susan and Dianne were (understandably) tired from three hours in the water so it fell to Lily and I to do the exploring.
Well, as Lily had already spent time in the waters of British Columbia, she knew what she was doing. Me, not so much. The dry suit I used was leaky and rather too large. I could feel the water creeping in as I searched for the elusive pike. The quest was in vain, though I encountered large numbers of stickleback.

When I returned to dry land some twenty minutes later and removed the drysuit, I was utterly soaked. For all the good it did, I might as well have jumped in without it. So a quick return back to home base was in order to get me into something warm and dry.
On the way back, we saw a female moose grazing at the roadside (no pictures; we were going too fast. But take my word for it!)

Here's hoping the good weather holds out for us. Tomorrow is Cheney Lake: the search for more males!

On Stickleback & Socializing

As a certain mustache-ioed lab member recently put it:
"The problem with Alaska is there are too many Alaskans!"

Miguel & I have been trapping for stickleback in the Mat-Su Valley for a week now and what strikes us is the far-reaching and very recent development in this, the greater Anchorage area. In particular the "sleepy" hamlet & hometown of Sarah Palin, Wasilla is bustling with a major highway and boasts a number of large chain stores such as Target, Super Walmart, Lowe's and Sportsman's Warehouse. As we drive this stretch of road everyday we were regaled by Mr. Mustache about the good ole days before there were any stoplights to slow us on our way to the 70+ lakes we hope to trap at in the next 4 weeks. The lakes themselves are particularly juicy targets for suburbia's encroachment. It is rare to trap at a lake (most are pond-sized) with any less than 3 or 4 houses and many have entire subdivisions catering to a lake lifestyle. We drove by a private community that was strictly for pilots of float planes. The infrastructure to support these communities is staggering. Miles upon miles of winding road systems and the gravel excavation pits from whence they came. Downed timber and trash litter the sides of the road and "For Sale" signs are just about as common as "No Trespassing/Private Property" here in the land of libertarians.

So what does all of this mean for two rogue stickleback collectors? It means that in order to collect at these lakes we often do it on private property and that means befriending the locals. On a typical day we pull up to any number of properties to inquire if we may set our traps for collecting. Most people are more than happy to allow us on their land and, in fact, often wish to learn more about the "minnows" they find off of their dock. We often find ourselves teaching the very young and the not so young that stickleback are indicators of lake health, that the beautiful birds they enjoy must feed their young something and if you let northern pike invade there will be no fish to support the birds. These impromptu opportunities to educate the locals is lovely and sometimes they even teach us a thing or two! Today a homeowner recounted observing a stickleback turn on his side & shimmy in the sun. He was quite pleased to see that this important behavior went right into the notes. Often these kind folks invite us to stay or gift us salmon fillets. In addition to humans, we often get "help" from the fuzzy family members of these properties. Today a standard poodle knocked aside our traps and a few days ago, we met monty, a three month old fearless pup who led us right down the long muskeg trail to where we might trap and bounced alongside us through the whole process. We even had a particularly curious kitty who was drawn in by the smell of fish.

Of course, the story of increasing anthropogenic inputs influencing lake productivity and the resulting behavioral and life history shifts is one that our lab continues to investigate. It seems clear that this story is commonplace across these lakes as more folks choose to live the lake lifestyle. Trapping on these beautiful lakes, across variable degrees of development, will bolster our understanding of such patterns. And in the process we will meet many a friendly Alaskan and maybe, just maybe, take home a fillet or two.
