Although I am not a botanist, the variety of mosses and liverworts covering the ground and hanging from trees in the native Azorean humid laurisilva forests amazes me. Pico is the second largest island of the […]

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 […]
Conservation issues in Southeastern Asia – from the insects’ point of view
Southeast Asia, a hotspot for biodiversity, many endemic to the region. However, insects are also facing a number of threats, including habitat loss, climate change, the use of pesticides, as well as the increasing demand for insects (mostly illegally) sourced from the wild.
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 […]
Effects of grazing on the invertebrate assemblages in Scottish uplands
The Glen Finglas Projects is a large-scale and long-term experiment investigating the effects of four different grazing regimes, no grazing, high-stock sheep grazing, low-stock sheep grazing, and low-stock sheep mixed with cattle grazing (+ the occasional deer), on Scottish upland ecosystems. I was involved in the arthropod collection and sorting/identification […]
