Introduction
I am an evolutionary scientist using genomic and morphometric approaches to tackle questions on animal taxonomy, speciation, evolution and conservation. My work currently focuses on the amphibians of Madagascar.

The present corrigendum corrects errors that occurred in: Petzold A., Magnant A.-S., Edderai D., Chardonnet B., Rigoulet J., Saint-Jalme M. & Hassanin A. 2020. First insights into past biodiversity of giraffes based on mitochondrial sequences from museum specimens. European Journal of Taxonomy 703: 1–33. https://doi.org/10.5852/ejt.2020.703

Intensified exploration of sub-Saharan Africa during the 18th and 19th centuries led to many newly described giraffe subspecies. Several populations described at that time are now extinct, which is problematic for a full understanding of giraffe taxonomy. In this study, we provide mitochondrial sequences for 41 giraffes, including 19 museum specime...

Molecular data are now commonly used in taxonomy for delimiting cryptic species. In the case of giraffes, which were treated as a single species (Giraffa camelopardalis) during half of a century, several molecular studies have suggested a splitting into four to seven species, but the criteria applied for taxonomic delimitation were not fully descri...

For decades, the genus Pelomedusa has been thought of as containing only a single species that is widely distributed in sub-Saharan Africa, the Arabian Peninsula, and Madagascar. However, ten species and up to five candidate species have been recognized recently. For these taxa, ecological information is scarce and distribution ranges are often onl...

Mitochondria- as well as p53-based signaling pathways are central for the execution of the intrinsic apoptotic cascade. Their contribution to rubella virus (RV)-induced apoptosis was addressed through time-specific evaluation of characteristic parameters such as permeabilization of the mitochondrial membrane and subsequent release of the pro-apopto...

Recent research has shown that the helmeted terrapin (Pelomedusa subrufa), a species that occurs throughout sub-Saharan Africa, in Madagascar and the southwestern Arabian Peninsula, consists of several deeply divergent genetic lineages. Here we examine all nominal taxa currently synonymized with Pelomedusa subrufa (Bonnaterre, 1789) and provide mit...

Using nearly range-wide sampling, we analyze up to 1848 bp of mitochondrial DNA of 183 helmeted terrapins and identify a minimum of 12 deeply divergent species-level clades. Uncorrected p distances of these clades equal or clearly exceed those between the currently recognized species of Pelusios, the genus most closely related to Pelomedusa. We cor...
