I like Mathematica’s and Matlab’s log-log plots with logarithmic axes and linear tickmarks (and gridlines). In a way, they enable to imagine both multiplication and addition in a single figure. They also enable to more exactly visually connect data points with values. I haven’t found a simple ‘one-liner’ that’d do such plots in R. In… Read More »
Elisabeth Kolbert: The Sixth Extinction. Published on Feb 2014 by Henry Holt & Co., New York. The 2015 Pulitzer prize in the General Nonfiction category (awarded on May 28) went to Elisabeth Kolbert for her book on science of extinction, which also happens to be an intro to conservation biogeography. The book has a wide… Read More »
I used to be involved in a large EU-funded collaborative project. It gave me an opportunity to do fun basic science, and also an opportunity to see the kind of lingo that is used in order to get a big EU project funded. The project promised: "Our results will be relevant for policy and decision-making… Read More »
This post advertises our new Ecological Applications paper which is in press. Imagine that there would be a tool that could make hi-res images out of low-res ones, just like this: Such tool would be really useful for creating maps of things for which we only have a very crude (low-res or coarse-grain) spatial information,… Read More »
Spatial correlograms are great to examine patterns of spatial autocorrelation in your data or model residuals. They show how correlated are pairs of spatial observations when you increase the distance (lag) between them - they are plots of some index of autocorrelation (Moran's I or Geary's c) against distance. Although correlograms are not as fundamental… Read More »
These are materials for the first practical lesson of the Spatial Scale in Ecology course. All of the data and codes are available here. The class covered a 1.5h session. R code for the session is also at the end of this post. The following advices and ideas are mostly my personal opinions, they were… Read More »
