Click here to read the full post at WildlifeSNPits: September 7th marks the anniversary of a spectacular failure in Australian wildlife conservation. On this day in 1936, the last known thylacine, the largest marsupial carnivore and the only member of the family Thylacinidae, died in captivity in a Hobart zoo. Today, this day is recognised (I cannot bring myself to write “celebrated”) as Threatened Species Day. In July this year, the Australian Government launched a new Threatened Species Strategy at a summit in Melbourne. Many conservationists, myself included, have welcomed these plans, which include targets to improve the conservation status of 20 mammals, 20 birds and 30 priority plant species by the year 2020. Those who know me will know of my love for bandicoots, bilbies and quolls, so it should be no surprise that I’m delighted to see some of these species included in the new strategy. But still, in the days following the announcement I found myself having conversations with an assortment of friends and colleagues that went along the lines of “this is great but what about the threatened fish… or reptiles… or amphibians… or insects… or crustaceans…" If we are serious about wildlife conservation and the preservation of ecosystems, we can’t afford to focus only (or mostly) on the cute and the fluffy. We need to strive to conserve all wildlife and especially to prevent the loss of species that play important ecological roles. We need to save the pollinators, the predators, the detritivores, the ecosystem engineers… there are many of these and, although some may have fur or feathers, most of them don’t!

Click here to read the full post at WildlifeSNPits: Today’s post is prompted by a conversation I had with a man I sometimes see at the local dog park. Early one morning a few weeks ago, while our pooches played, we discussed species concepts. This man expressed his frustration at his biologist friends’ constant efforts to describe and delimit species. This obsession with naming and renaming was a mystery to him, and he thinks it a waste of effort. To paraphrase him: so mistakes were made in the past, but surely now we can just all agree to accept the status quo and refrain from splitting and merging and reclassifying any more species. And if we discover something new, well, if two groups of individuals can interbreed then they are the same species and if they can’t interbreed then they are different species, right? Except that it’s not quite that simple.  |
