El 1 de enero, para el juliano es el día 1.

El 31 de enero es el día 31
-
El 1 de febrero es el día 32.

Keeping it Real – Tweets on Urban Ecology and Watershed Restoration
Portland, OR is a hotbed of restoration activities in a highly urban area. Yes, restoration of natural environments can take place in a degraded and lived-in habitat (the big city). Today, I’m attending the 2011 Urban Ecology and Conservation Symposium at Portland State University.
For the first time, I – Water for the Ages – am tweeting from a conference with a focus on topics related to watersheds. Keep on eye on my twitter for updates. This conference is hosted by the Urban Ecosystem Research Consortium of Portland/Vancouver.
“The mission of the UERC is to advance the state of the science of urban ecosystems and improve our understanding of them, with a focus on the Portland/Vancouver metropolitan region, by fostering communication and collaboration among researchers, managers and citizens at academic institutions, public agencies, local governments, non-profit organizations, and other interested groups.”
