In landscape ecology, I emphasize how simple models can illustrate complex patterns—like how dispersal on an environmental gradient can look like species sorting and niche partitioning. So, I make toy models for class.

Honored to write a commentary recent Pederson et al paper with an AMAZING floating tree-ring chron from whitebark melting out of the ice. The way they use that (unique) resource with ESMs is so well done and gives us a look at the mid Holocene. Freq response y'all! www.pnas.org/doi/10.1073/...

You can see the history of the landscape everywhere: An oak that probably grew in a pasture with scattered trees, likely savanna before that, now surrounded by younger trees. Within sight of our house, which sits close to the edge of open prairie on the 1830s public land survey sketch map.

As resorts and snow sport enthusiasts gear up for winter’s #snowfall, DRI's Dan McEvoy is preparing to figure out just how much snow the slopes will see this season. Read the full @usatoday.com article on their website: bit.ly/1000inchesof... #DiscoverDRI
1,000 inches of snow? It's possible on the USA's snowiest mountain.
The “snowiest” label could depend on whether you’re talking about where the most snow falls or where the most snow piles up.
