I am working again with ants this summer, and have been getting out a bit for work and on the weekends for special outings. I have been accumulating a number of excess photos over the past few weeks that don’t really fit in with the special topics (Guyana, Expeditions, Okanagan) so I have put them together here. I hope you enjoy them!
On our 12th day on the Rewa River, I had to part ways with Jonathan, Rambo, Josey and Brian. We headed downriver to where I could meet up with a group of Americans (up to study the Arapaima) who would take me back to Rewa Village. When we met up, we found them sitting at the riverside, having just finished a lunch of piranha. We arranged to meet the next day below the falls, and then bid adieu and went to set up camp. Because there was a pile of fish guts going begging, I placed the pile where a nearby Black Caracara could find it.
Travelling by boat offers many advantages over walking, not only in saved energy and efficiency, but also in that approaching wildlife is often much easier. I have covered many of the fish-eaters we saw along the riverside before, but here are some other species that we saw quite often along the Rewa.
The Okanagan is famous for its wine, and vineyards are raking it in and popping up like mushrooms on the floors of the valleys (this is actually one of the major development pressures threatening the scarce habitats). We found an unusual nitrogen subsidy taking place when we ended up on Road 22 outside Osoyoos. I will let the pictures do the talking.
This weekend, Catherine and I went out to Victoria to spend Mothers Day with my mom, who years ago suffered a debilitating illness caused by a spirochaete, Borrelia burgdoferi. This spirochaete, as far as we know, is transmitted in an enzootic cycle between ticks and various small mammals, reptiles and birds. When it spills over into the human population, it can cause symptoms ranging from mild rash and arthritis to fatal swelling of the brain and other organs, with just about everything in between represented. It is the most common arthropod-borne illness in North America, with hundreds of thousands of infections annually.
Primarily this disease is transmitted by black-legged ticks (Ixodes ricinus), but Ixodes pacificus, the Pacific black-legged tick is also a competent vector. While the main hotspots for Lyme transmission in Canada is southern Ontario and Quebec, there is growing evidence that locally acquired infections in BC may be becoming more common.
Nonetheless, the disease is often misdiagnosed, unrecognized, or otherwise not regarded as serious by a large proportion of the medical establishment, who are convinced that a quick round of antibiotics will kill the parasite. This is often true, but it seems that it is not always the case. Some of the most severe manifestations of Lyme disease go on to be persistent, leading to progressive debilitating symptoms. This chronic form of Lyme is the most controversial, as the leading treatment orthodoxy does not recognize the existence of long-term infection.
The existing diagnostic criteria are often insufficient, for while they pick up the so-called classic Lyme symptoms very well, an unknown percentage of sufferers never experience the characteristic bulleseye rash (erethema migrans) or early arthritic symptoms. Molecular techniques used for diagnosis are designed only for those sufferers presenting with classic Lyme symptoms, and even at this they have very poor performance. So the situation in Canada is there is transmission of a debilitating parasite, which can be difficult to diagnose and treat, and medical and disease-control officials are unwilling to acknowlege the extent and nature of the problem.
Anyway, something is being done to address this illness, both from a public information perspective as well as from a fundraising one.
Two young fellows from St. Catharines, Ontario are undertaking a cross-Canada bicycle ride to raise money for and awareness of the disease. Daniel Corso and Tanner Cookson have a friend named Adelaine who was recently affected by Lyme disease, and realized what a tough and enduring problem the disease would be in her life. Discovering that the treatment options and diagnostic situation in Canada need to be updated, the two decided that their love of athletics may offer some kind of solution in the form of an endurance fundraiser. If nothing else, their ride might help raise Adelaine’s spirits.
On Sunday, they began their effort with a rally at Victoria’s Centennial Square, where they announced the ride and introduced their support team (their dads!). Since it was Mothers Day, they also made a special effort to acknowledge the mothers affected by the disease (like mine).
This is a really important health issue in Canada, and this is a great way to raise awareness and funds for research. If you happen to be on their route, be sure to go and cheer them on!
Below are some pictures from the Victoria events.
So Catherine and I have a week off this coming week, so we are planning to go for a bit of a vacation in the Okanagan. We will be mostly in the boonies, camping and searching for critters, so will be out of contact for a bit. It also means I will have to interrupt my series on the Guyana trip. When I come back it will be all Guyana, all Okanagan, all the time!
Our transport will be a venerable old Honda Civic that Catherine picked up for 500 bucks! It has new brakes and everything so should be a safe and reliable steed to carry us eastwards.
We are going to look for a long list of interesting animals, from scorpions and rattlesnakes to a few special spiders (Argiope, Antrodiaetus, Latrodectus [of course!)). Catherine and I will be trying to get some shots of rubber boas as well. Who knows what we will see! This will be a time for us to get out and get busy searching for whatever we can find. I think it will be awesome.
