In #drylands, plants don’t grow randomly — they self-organize into disordered hyperuniform patterns that help them use water wisely & endure extreme aridity. A beautiful hidden logic of nature, revealed in a new @pnas.org study doi.org/10.1073/pnas... including #Maestrelab alumni

Just installed mine yesterday! Unfortunately I don’t have any magic solutions. You shouldn’t need C++/Rtools, but for R itself just the installer from CRAN is pretty much what you need.

Quantitatively Testing Predictions From Mechanistic Models: A Case Study for Island Biodiversity A key test of an ecological model is whether it can quantitatively predict unseen aspects of the data not used in model fitting. Here, we test whether a model fitted only to island alpha diversity ca....

Achieving higher standards in species distribution modeling by leveraging the diversity of available software The increasing online availability of biodiversity data and advances in ecological modeling have led to a proliferation of open-source modeling tools. In particular, R packages for species distributi...
