Multi-level Voronoi maps in R
Voronoi diagram is a special type of tessellation that partitions a plane into regions close to each of a given set of points. The diagram is constructed by drawing a line segment between each pair of points, and then perpendicular bisecting each line segment. The intersection points of these perpendicular…

Long-term changes in Azorean native forest arthropods
Island biotas are threatened by habitat loss, anthropogenic pollution and climate change, as well as the effects of introduced species. The Azorean Biodiversity Group conducts several projects to assess the impact of these threats on the invertebrate communities in the Azorean archipelago. Most of the projects focus on the fauna…

Phenological changes in ground beetles
This was part of my PhD in Scotland. I used the long-term ground beetle (Coleoptera: Carabidae) dataset of the UK Environmental Change Network to investigate whether ground beetles start their activity earlier in the spring and cease it later in the autumn over a twenty-year period….
