New paper - Geomorphic Sensitivity and Ecological Resilience of Great Basin Streams and Riparian Ecosystems

 

There is a new(ish) report available on Research Gate - "Geomorphic Sensitivity and Ecological Resilience of Great Basin Streams and Riparian Ecosystems. Part I. Sensitivity and Resilience Concepts, Components, and Categories Part II. Assessment Protocol." You can access the report by clicking HERE. There is also a data publication that goes along with this report.  It is "Geospatial data for Great Basin perennial montane watersheds - geomorphology, hydrology, vegetation, disturbance and species" and it is available by clicking HERE.

New dataset - northern hemisphere day length rasters for each day of the year at 5 km resolution

 New day length rasters are available at:

These canned rasters can be used in place of the Day Length Tools for ArcGIS, which isn't as well suited for latitudes greater than 60 degrees. The new data are derived by extrapolating NOAA spreadsheet calculations - https://gml.noaa.gov/grad/solcalc/calcdetails.html.

New paper - Governing Ecological Connectivity in Cross-Scale Dependent Systems in Bioscience

Happy to announce that we have a new paper "Governing Ecological Connectivity in Cross-Scale Dependent Systems" published in Bioscience.  The paper came about from a meeting in February of 2020 held by the Delta Stewardship Council  in Davis, CA led by Annika Keeley.  I'm thrilled to have gotten to participate in this very interdisciplinary meeting.  You can view the paper by clicking HERE.  The full citations is:
