If you want to know what makes a Canadian lynx a Canadian lynx a team of DNA sequencers has figured that out.
24 September, 2018
- A team at UMass Amherst recently sequenced the genome of the Canadian lynx.
- It's part of a project intending to sequence the genome of every vertebrate in the world.
- Conservationists interested in the Canadian lynx have a new tool to work with.
<p>If you want to know what makes a Canadian lynx a Canadian lynx, I can now—as of this month—<a href="https://vgp.github.io/genomeark/Lynx_canadensis/" target="_blank">point you directly to the DNA of a Canadian lynx</a>, and say, "That's what makes a lynx a lynx." The genome was sequenced by <a href="http://www.umass.edu/newsoffice/article/umass-amherst-leads-team-first-sequencing" target="_blank">a team at UMass Amherst</a>, and it's one of 15 animals whose genomes have been sequenced by the <a href="https://vertebrategenomesproject.org" target="_blank">Vertebrate Genomes Project</a>, whose stated goal is to sequence the genome of all 66,000 vertebrate species in the world.</p><p>Sequencing the genome of a particular species of an animal is important in terms of preserving genetic diversity. Future generations don't necessarily have to worry about our memory of the Canadian Lynx warping the way <a href="https://io9.gizmodo.com/how-europeans-imagined-exotic-animals-centuries-ago-ba-1545362205" target="_blank">hearsay warped perception a long time ago</a>. </p>

It is a potential tool for future conservationists.</p><p>But what are the practicalities of sequencing the genome of a lynx beyond engaging with broad bioethical questions? As the animal's habitat shrinks and Earth warms, <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1111/j.1600-0587.2013.00629.x" target="_blank">the Canadian lynx is demonstrating less genetic diversity</a>. Cross-breeding with bobcats in some portions of the lynx's habitat also represents a challenge to the lynx's genetic makeup. The two themselves are also linked: warming climates could drive Canadian lynxes to cross-breed with bobcats. </p><p>John Organ, chief of the U.S. Geological Survey's Cooperative Fish and Wildlife units, <a href="https://www.masslive.com/expo/news/erry-2018/09/e565d904646142/umass-scientists-oversee-first.html" target="_blank">said to MassLive</a> that the results of the sequencing "can help us look at land conservation strategies to help maintain lynx on the landscape."</p>

Consider the fact that the food found in a landscape, the toxins found in a landscape, or the exposure to drugs can have an impact on genetic activity. That potential change can be transmitted down the generative line. If you know exactly how a lynx's DNA is impacted by something, then the environment they occupy can be fine-tuned to meet the needs of the lynx and any other creature that happens to inhabit that particular portion of the earth.</p><p>Given that the Trump administration is considering withdrawing protection for the Canadian lynx, <a href="http://www.spokesman.com/stories/2018/jan/11/federal-governments-step-toward-delisting-canada-l/" target="_blank">a move that caught scientists by surprise</a>, it is worth having as much information on hand as possible for those who have an interest in preserving the health of this creature—all the way down to the building blocks of a lynx's life.</p>
