new ArcUser article - Mapping with Population-Weighted Centroids

 

I just discovered that Esri published this short article that I wrote on population-weighted centroids rather than geometric centroids. You can view the ArcUser article HERE. If you are interested in accessing the data used to make these maps please click HERE. This article was inspired by the endless hours looking at COVID maps at the height of the pandemic and noticing that Washoe County's dot was centered on Gerlach instead of Reno on pretty much every map.

new paper - Adaptive divergence despite low effective population size in a peripherally isolated population of the pygmy rabbit, Brachylagus idahoensis in Molecular Ecology

 Nathan Byer is the lead author on our new landscape genomics paper on pygmy rabbits.  The paper is published in Molecular Ecology and is somewhat of a companion to a hopefully forthcoming landscape genetics paper on pygmy rabbits.  You can view the paper by clicking HERE.

new paper - Phenology-based classification of invasive annual grasses to the species level

The Great Basin Landscape Ecology Lab and Center for Transformative Environmental Monitoring Programs has a new paper in Remote Sensing of Environment that uses drones to map two different invasive grasses in the Great Basin - cheatgrass and medusahead.  Our study found that we could effectively differentiate the species using three well-timed flights and a simple red-green-blue camera.  Using unmanned aerial vehicles we were able to accurately map the occurrence of these two different invasive species on the landscape.
