Ad hoc instrumentation methods in ecological studies produce highly biased temperature measurements

In any region-spanning collaborative effort, using (as-much-as-possible) unbiased methods is of course desirable. Check out the recent paper by Terando et al. It’s open access, available here: http://onlinelibrary.wiley.com/doi/10.1002/ece3.3499/epdf They experimentally compared 11 different sensor brand and shield combinations to weather station data, and found that quite a few methods had a positive bias. It’s notContinue reading Ad hoc instrumentation methods in ecological studies produce highly biased temperature measurements

Longest running successional plot network in the world: All photos

The longest running ecological plot network in the world looking at succession (1916-present) is in Glacier Bay, and now all available photographs have been compiled.  They show a plant community evolving, from mostly bare rock to a variety of current states – spruce, alder, and willow, very different endpoints and something apparently unique to this portionContinue reading Longest running successional plot network in the world: All photos

New map of yellow-cedar decline published

A new map of both the range and decline of yellow-cedar has been published in Global Change Biology with help from researchers in Alaska, BC, and Washington.  The high resolution range map stretches from northern California to southcentral Alaska, from sea level in the north to treeline in the south.  The decline, now quantified atContinue reading New map of yellow-cedar decline published
