Valentine’s Day in 2025 is a special one: we introduce an Anilovely new species from the Tsingy de Bemaraha karst of western Madagascar: Anilany karsticola. The species description is published open access in the 14 February issue of the journal Salamandra, and you can read it here! In 2006, a […]
The ridge of mountains that runs parallel to Madagascar’s east coast descend in short order into rolling hills, followed by sand dunes, and ultimately meet the Indian Ocean. These rolling hills and sand dunes were once cloaked in low-elevation humid forest and littoral forest. Today those habitats are some of […]
In the 15th of August issue of the journal Salamandra, my colleagues and I published a new species of leaf-tailed gecko from northern Madagascar, Uroplatus garamaso! You can get the PDF of the description here. In 2009, I was on a voluntourism trip to northern Madagascar. I was there to study […]
About a year ago, I decided to set out on a major curatorial project, as one of my first large-scale projects for the herpetological collections of the Natural History Museum of Denmark (NHMD), where I am the curator of reptiles and amphibians. The project: to update the taxonomy and organisation […]
How does an ecological gradient, like the slope of a mountain, affect the evolution of organisms that interact with it? Does it promote ecological speciation? And does it act the same way in different organisms? These questions are largely still unanswered. Today, my colleagues and I have published a study […]
Here at the end of 2022, it is time to do as I have done since 2016, and give some reflections on the year. These focus mostly on the academic aspects of the year, though for reasons that will soon become apparent, the personal and academic aspects of 2022 were […]
When you walk along streams in Madagascar, you frequently hear sounds like doors creaking and stomachs gurgling. These are the calls of little muddy-brown frogs in the Mantidactylus frog subgenus Brygoomantis. Today, my colleagues and I have published our magnum opus on these charming but secretive little frogs, describing 20 new […]
For my twelfth or thirteenth birthday, my parents gifted me a copy of the then-newly published Natural History of Madagascar. This mammoth tome, comprising 1728 pages, set a benchmark in the literature on every topic it covered, and it covered almost everything you could think of. I spent many nights […]
Open access (OA) is increasingly demanded by funders, and of course is desired by researchers and readers alike. Yet some journals charge incredibly high fees for you to publish your research open access. This has led to a lot of researchers being resigned to either publish behind a paywall, or […]
I have just returned from three weeks at the Udzungwa Ecological Monitoring Centre (UEMC) in central Tanzania, just outside Udzungwa Mountains National park, where I have been teaching as one of four main lecturers on a Field Training Course, part of the Erasmus+ project ‘Developing curricula for biodiversity monitoring and […]
Today, my colleagues and I have published a monograph on part of the gecko genus Lygodactylus, describing eight new species from Madagascar in the journal Zootaxa. Lygodactylus are diurnal geckos, but most species are not as flashy as their cousins, the Phelsuma day geckos. They come mostly in mottled greys […]
Another year is over, and 2021 seemed still more full and stressful than 2020! So here are some reflections on my year from an academic perspective. The first of January 2021 saw me starting a new job: PI on a three-year German Research Foundation (DFG) funded PostDoc project in Michael […]
I am thrilled to announce that I will taking up the post of Curator of Herpetology at the Natural History Museum of Denmark, and Tenure-Track Assistant Professor of Vertebrate Zoology at the University of Copenhagen on the 1st of September, 2021! Having just started a PostDoc at the University of […]
The herpetofauna of the EU is relatively well studied, and it is rare that species new to science are discovered. Today, my colleagues and I have described a new species of blindsnake from the island of Mayotte—an island that lies in the western Indian Ocean between Madagascar and Mozambique, but […]
We have just published the discovery of a new species of chameleon, Brookesia nana, which is a new contender for the smallest reptile—and therefore the smallest amniote vertebrate—in the world! Our new paper is published in the Open Access journal Scientific Reports. Nine years ago, my colleagues reported on a few […]
