“Frontier Justice”

This article is suitably flippant about people dying. A hunter -sorry – poacher in Kruger National Park was killed by hippos and eaten by lions: “While

Friday Insanity 2.28

The importance of tagging things is becoming obvious. I had to go through every video to ensure this hadn’t been posted. On a separate note, could they have maybe gotten somebody a little less abrasive t narrate this thing? Like Gilbert Gottfried?

Threats to World Economics

This is an interesting conceptual map of best rx online pharmacy risks to the world economy. Biodiversity loss is included, though I bet a lot of conservation biologists would disagree with the missing links. Biodiversity could certainly be used as an investment in infrastructure (ecotourism, ecosystem services), preventing food price volatility, transnational crime and corruption and international terrorism cialisfordailyuse-right.com (Somali pirates), and how on earth did they leave out Pandemics? The really interesting thing, though is their plot of likelihood cialis coupons 2013 and severity. Biodiversity loss is about midrange in the likelihood scale, but fourth-lowest on the severity scale. Meanwhile, asset price collapse where to buy cialis over the counter is listed as the highest likelihood and highest severity. It’s an fascinating view on how economists think about biodiversity loss.

Between an endangered rock and a critically endangered hard place

We teach and talk about ecology as a tale of balance: the decline of one population generally leads to the increase in another. Nature abhors a vacuum. The cycling of predators and prey. Unfortunately, that complexity leads to a lot of problem in application. I can’t think of a better example than Macquarie Island, where cats were introduced about a century ago. The cats then destroyed the local community of birds. Unfortunately, when managers removed all the cats, the rabbits took over. There have been a bunch of similar stories on unanticipated ecological results and other catch-22s recently. Where I work, it’s not clear whether management should focus on the endangered San Joaquin kit fox or its prey, the endangered giant kangaroo rat. Managers in Washington are facing the same problem with orcas and Chinook salmon (you’ll recall that managers in Oregon had no such qualms about killing California sea lions that were eating salmon). Or take this study that shows prescribed burns in the Western U.S. could actually decrease our carbon footprint. Consider that swift populations in the UK are declining due to housing renovation projects.

There’s an emerging science on ecological traps, where changes in habitat (generally human-caused) lead to novel environments that appear to be high quality for a species, but are in fact low quality. In the Negev desert, for example, managers establishment of pits and dykes to increase moisture in certain areas led to increased mortality for an endemic lizard. The increased moisture led to trees, which served as perches for shrikes, who preyed on the lizards. The lizards had no exposures to trees and so didn’t anticipate the negative consequences.

In a recent discussion section for our wildlife ecology class, students were asked to draw parts of the Yellowstone ecosystem, to try to understand the consequences (direct and indirect) of removing wolves. After a sufficient number of convoluted arrows had been added among humans, wolves, elk, aspen, beaver, fish, soil, &c. &c., one student shouted “It’s all connected, man!” A total Berkeley moment.

Another sad loss

Former Secretary of the Interior Stewart Udall passed away over the weekend. He did as much as Muir and Roosevelt to create the Myth of Wilderness that inspired so many Americans, helping to enact the Wilderness Act in 1964 and helping to create Redwood National Park, Cape Cod National Seashore, and Point Reyes National Seashore. He fought in WWII. He led a lawsuit in the late 1970s against the government on behalf of Navajo uranium miners. The Udalls are one of the great (perhaps unsung) political clans of the country. He was a Great American, and one of my heroes: “Over the long haul of life on this planet, it is the ecologists, and not the bookkeepers of business, who are the ultimate accountants.”

The University of Arizona houses his manuscript collection.

Bob Edwards remembers Steward Udall: “I have lived in Washington, DC far too long to have political heroes, but Stewart Udall was the model of what a public servant should be.”
