The Final Days in British Columbia

A belated post this might be, but I felt it necessary to share with our readers the last days of the 2010 expedition to the north.

After a week in Alaska, the strangest thing about British Columbia was that the sun actually set. Granted, it set fairly late, around 9:00 PM, but there was still definite night and day.
For the end of our trip to British Columbia, Team Animal Behavior was on the BC mainland. Instead of a motel, we stayed with one of Susan's old friends, Norma, a sweet lady who had a great many stories to tell and who is very used to stickleback research.
(It seems that everyone up north is. We would be working at lakes and people would drive by us and ask "Are you the stickle folks?")

Our primary goal on the mainland was to investigate Hotel Lake. Lily and gang had scouted it out earlier in the summer to try and find courting and parental males, but the lake was empty then.Unfortunately, when Dianne, Lily and I explored the lake, we had similar bad luck. There were fry everywhere, clouds and clouds of them, but very few adults, and even fewer breeding ones.We tried twice, and laid out traps, all met with minimal success.

Another day saw us trekking to the well-hidden Ambrose Lake. To get there, we had to drive up rocky trails and hike through thick forests and over muddy ground. The lake, however, was beautiful, and there were plenty of parental stickleback.



The parental fish in this lake were very brightly colored. Even the females, usually drab or silvery, were shades of bright gold and copper. Unfortunately, if the captured fish spent about twenty minutes in a bucket, they lost their coloration. Our collection, then, looked less impressive when preserved then they did in the water.

Our last day was spent preserving all the stickleback we'd caught so they could be shipped back to Massachusetts. Working with that many dead fish and that much formaline is unpleasant, but with three of us working on it, the job didn't last long.

The trip back to the east coast required a long car drive back to Seattle and early flights. And then, we were all back in Worcester, where there were dishes upon dishes of stickleback eggs that needed attending to and fry that needed feeding.

Being a Journey Across the Border

The Canadian border, that is.

Team Animal Behavior departed for British Columbia on Tuesday night. The flights landed in Seattle at 5:30 AM, but there was no rest even then. The car had to be picked up (a monstrous Jeep, the only thing that could fit all the luggage) and it was a three-hour drive over the border to the ferry which would take us to Vancouver Island. Well, needless to say we were all very tired, but there were fish to collect and lakes to explore, so we could not be stopped! The following day saw us traveling to Sproat Lake to collect females for color observations.
On the way, though, we had a chance to stop at the Cathedral Forest.

It's an amazing place. The trees are immense and almost everything is smothered in drooping moss. The ground is covered in large ferns and the whole place feels primeval, like something time forgot. I like to think of it as Jurassic Park, minus the dinosaurs.

The trees are quite big. This one was over 500 ft tall.

Sproat Lake was very nice, despite being cold. The females there are very pretty. There was one that was gold and iridescent. Unfortunately, we came a bit early in the mating season to see much. About all we could see were some very eager males, some who would court with anything that moved.

Today was an early start so we could do Crystal Lake before access to it was shut off. The lake is in the middle of a partly clear-cut forest, but it's still lovely, and we were much more successful today than anticipated (35 captured males. Susan is tireless).

Tomorrow is another early start to catch an early ferry off the island. Hoo boy.

Being an Expedition to Seward

Yesterday was an early start for the animal behavior group. We had a two and a half hour drive to Seward and Resurrection Bay planned to catch some fish! Along the way, we stopped many times to take pictures of beautiful Cook Inlet and the mountains.
As we drove it began to get colder. We must have been getting higher into the mountains, because there was snow everywhere. Snow. In June.

It was a strange thing to see, but this is why they call it the Great White North!

When we finally arrived in Seward we had to do a bit of off-road driving to get to the lakes. Ponds, more like. We were looking at a large group of ponds in the middle of a large muddy field filled with knee-high grass. My boots and pants were covered in mud and pollen after walking around. The scenery was great though, even though we had to listen to the sounds of seagulls and crows screaming at each other.

After lunch we got to work. Traps were laid to catch fish for our crosses and the equipment to measure color was set up. Lily manned the color station while the rest of us patrolled the edges of the pond, nets in hand, searching for courting and parental males. When the sun came out from behind the clouds, this was an easy task; the pond was shallow and the water clear, and in the sunlight we could see straight to the bottom. The males were brightly-colored and most were guarding nests built into the muskeg-y bottom. Watching them was a fascinating experience. Reading about courtship behavior is one thing. It's quite another to see it in action, to watch the males chase off rival males, to see the males and females dance about each other, to observe how diligently the males guard their nests and just-hatched fry. Watching multiples males and multiple interactions on a large scale was somewhat dizzying, but gave me a new appreciation for the stickleback mating process.

During our day we had a visitor! A woman walking her dogs saw us gathering specimens and asked about the threespine stickleback. She was treated to the full explanation of our purpose and the evolutionary significance of the fish. She seemed quite interested. It's nice to know that locals want to learn more about the work we do here.And her dogs were very friendly.

There's also nothing quite like cold pizza for lunch during field work. Mmm-mmm.

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!
