DNA barcoding plants with citizen science

28 08 2013

hikingI was contacted recently by Oscar Jaslowski of Microryza (a web platform that allows scientists to post research  ideas and collect contributions from web visitors) about a project getting underway in Alaska by Ellen Jorgensen of Genspace. He suggested it might make a good post for ConservationBytes.com, and I agreed. Thanks for the contribution, Ellen & Oscar.

There’s nothing so final as watching the bush pilot take off in his tiny plane, leaving you stranded in the Alaskan backcountry. We had plenty of food for a three-day expedition, but no satellite phone or any other way to contact anyone. In Alaska, the phrase ‘primordial indifference’ pretty much sums up your relationship with the vast, glacier-carved landscape. Mother Nature does not care if an ant like you lives or dies.

Our destination, the Skolai Valley, is located about 480 km (300 miles) east of Anchorage, in the heart of Wrangell-St. Elias National Park. At a whopping 5.3 million hectares (13 million acres), it is the largest national park in the United States, and probably one of the least-visited. Much of its forbidding territory is snow-covered and similar to the Himalayas. In fact, the size of the massive ice fall that towers over the town of McCarthy, the origin of our flight, is exceeded only by one near Mt. Everest. But winding through the glaciers and snowfields are alpine valleys that are a backpacker’s dream. And Genspace, the nonprofit science-based organisation that I direct, was lucky enough to have received funding in 2012 to launch this expedition to Skolai.

Our  mission: to barcode wild Alaskan plant life. Two of us headed down into the river valley and the other two climbed up to the level of the mountain pass to survey more alpine vegetation. We were carrying portable plant presses – normally something too bulky for backpacking, but necessary for this trip. Read the rest of this entry »





Does conservation biology need DNA barcoding?

5 01 2012

In November last year I was invited to participate in a panel discussion onthe role of DNA barcoding in conservation science. The discussion took place during the 4th International Barcode of Life Conference (which I didn’t actually attend) in Adelaide, and was hosted by that media-tart-and-now-director-of-the-Royal-Institution, Dr. Paul Willis.

Paul has recently blogged about the ‘species’ concept as it relates to DNA barcoding, which I highly recommend. It also prompted me to write this post because now the video of the discussion is available online (see below).

Now, the panel was a bit of a funny set-up in a way – I was really one of the only ‘conservation biologists’ represented (Patrick O’Connor and Andy Lowe perhaps excepted), with the rest mainly made up of molecular people (Pete Hollingsworth, Bob Hanner, Karen James) – and I was told prior to the ‘debate’ that I was meant to be the contrarian (i.e., that there is no role for DNA barcoding in conservation).

Fundamentally, I don’t actually embrace the contrarian view on this one given that I see no reason why DNA barcoding can’t enhance or refine our conservation knowledge and skills. But the ‘debate’ did raise some important issues about technological advancements in the application of conservation science to real conservation.

I suppose that prior to getting stuck into the polemic I should define DNA barcoding for the uninitiated; it’s a basic technique that analyses short sequences of DNA with the sole purposes of identifying from which species they come. Imagine walking through the bush with a barcode scanner and pointing at random species you see and getting an instant identification read-out without actually knowing the species beforehand. You can see why it’s called ‘barcoding’ because it is like running products through the check-out to get instant price details. Read the rest of this entry »
