Check it out: another way to search for research. JournalMap is a scientific literature search engine that empowers you to find relevant research based on location and biophysical attributes combined with traditional keyword searches. It works ok, I found one of my papers, not others. But the interface it quick and intuitive.
I recently attended the 2014 annual meeting of the Western Section of the Wildlife Society in Reno CA. The focus of the conference was on harnessing citizen science toward greater conservation.
- Peter Bloom discussed red-tailed hawk movements from banded bird recovery. The birds are banded as juveniles and observed by citizens and scientists. In this way their movements can be mapped: across southern California, across the Pacific flyway, and across the US.
- Joe Burnett presented on the use of GSM transmitters to track California condor (the largest flying bird in north America) movement patterns. He caught us up on condor recovery and current threats (lead poisoning from foraging on wild game) to condors. He showed some very nice visualizations of wild condor flights between Ventana and the Pinnacles (including some stops for water and dead animal chomping) from the GSM transmitters and Google Earth.
- Shannon Rich looked at migration patterns of flammulated owls using light-level geolocators. "What is a flammulated owl”? you say: I will tell you. They are super cute tiny owls, with neat flame-like markings on their face and body. Geolocators are small (~1g) that record ambient light levels during the day, and from timing of sunrise and sunset, you can get latitude and longitude. These are not sending out signals, and you need to recapture the owl to download data. As always, I am stunned by the dedication and time it takes for wildlife biologists to gather their careful data on animal movement.
- Russ Bryant talked about native honeybee habitat in North Dakota. He talked about the important services that bees give us: 95 agricultural plants benefit from pollination services (estimated at $15b). I did not know that ND is the top honey producer in the US. Colony collapse across the US has been profound. They used INVEST to explore the role of land cover and bee pollination to produce a pollinator habitat index, and a habitat connectivity for areas where bees had been captured.
In the climate change session, I heard from a range of speakers on practical adaptation strategies, curriculum for climate change education (Whitney Albright), new tools and reports for grassland bird species conservation (Ryan Diguadio), landscape-scale conservation planning for bobcats in the San Diego area (Megan Jennings), and some neat genetics of the SF Bay’s salt marsh harvest mouse (Mark Statham). Also, Curtis Alling talked about local, regional and state climate preparedness planning, and dedicated a slide to cal-adapt.org. Nice!
I also got to catch up briefly with ESPM grads Sarah Sawyer who is now at the Forest Service and Tim Bean, who is thriving at HSU. Alice, he suggested a trip up to Redwood State Park to check out the dark figure of crime in the tall trees.
An interesting position piece on the appropriate uses of big data for climate resilience. The author, Amy Luers, points out three opportunities and three risks.
She sums up:
"The big data revolution is upon us. How this will contribute to the resilience of human and natural systems remains to be seen. Ultimately, it will depend on what trade-offs we are willing to make. For example, are we willing to compromise some individual privacy for increased community resilience, or the ecological systems on which they depend?—If so, how much, and under what circumstances?"

Lots of exciting sharing this week!
A new high-resolution global map of forest loss and gain has been created with the help of Google Earth. The interactive online tool is publicly available and zooms in to a remarkably high level of local detail - a resolution of 30m. Snapshot of Russia here (green = forest, blue = gain, red = loss):
Results from time-series analysis of 654,178 Landsat images from 2000–2012 characterize forest extent and change. Between 2000 and 2012, according to this analysis, the Earth lost a combined "forest" the size of Mongolia. http://www.bbc.co.uk/news/science-environment-24934790
Here is the abstract from the accompanying paper in Science:
Quantification of global forest change has been lacking despite the recognized importance of forest ecosystem services. In this study, Earth observation satellite data were used to map global forest loss (2.3 million square kilometers) and gain (0.8 million square kilometers) from 2000 to 2012 at a spatial resolution of 30 meters. The tropics were the only climate domain to exhibit a trend, with forest loss increasing by 2101 square kilometers per year. Brazil’s well-documented reduction in deforestation was offset by increasing forest loss in Indonesia, Malaysia, Paraguay, Bolivia, Zambia, Angola, and elsewhere. Intensive forestry practiced within subtropical forests resulted in the highest rates of forest change globally. Boreal forest loss due largely to fire and forestry was second to that in the tropics in absolute and proportional terms. These results depict a globally consistent and locally relevant record of forest change.
