Systematics, biogeography and conservation
of dragonflies and damselflies (Odonata)

With their amphibious habits and habitat sensitivity, Odonata respond strongly to change above and below the water surface. Such change can be natural or anthropogenic, e.g. deforestation and erosion versus gradual landscape conversion and altering river courses. Odonate dispersal capacities range from negligible to intercontinental and from airborne (adults) to waterborne (larvae). Thus Odonata are suitable to evaluate habitat connectivity and environmental change in the long and short term (biogeography, climatology, conservation biology).

My fundamental interests are:
Systematics - How species are related and how they can be identified. Taxonomy must be made accessible through keys and field guides.
Biogeography - Which species are found where and why. Faunistic data can be explained with historical biogeography, and larval and adult ecology and dispersal.
Conservation - What species tell us about their habitat, its history, state and future. Systematics and biogeography are essential to conservation.

CV summary

My passion for natural history began when I was nine, living in Egypt. After obtaining an MSc in evolutionary biology, biogeography and systematics at Leiden University in 1998 (cum laude), I worked on African and European Odonata at the National Museum of Natural History (now NCB Naturalis) in Leiden, The Netherlands.

I obtained a PhD at Leiden University in May 2007, with accumulated work on the biogeography and taxonomy of Afrotropical Odonata (thesis), publishing over forty papers on the subject since 2002. The African landscape is ever-changing under geological, climatic and human influence. Study of its over 700 species of Odonata helps understand the continent’s past and future. Research was undertaken in numerous museums and in sixteen African countries, including during three of Conservation International’s (CI) RAP biodiversity assessments. I shared the Worldwide Dragonfly Association (WDA) outstanding achievement award for my African work in 2005. As a member of the IUCN Odonata Specialist Group since 2003, I contributed to the Freshwater Biodiversity Assessment of Africa (2006-2009), resulting in Red List assessments for all species. A handbook for the 470+ species of eastern Africa (Sudan through eastern DRC to Mozambique) will appear in 2011.

I became curator of invertebrates at the National Zoological Collection of Suriname (NZCS) in 2007, initiating collaboration with Naturalis: supported by the Dutch Foreign Ministry, Naturalis’s Suriname collections will be disclosed in databases and books. I returned to Naturalis in 2008, co-funded by CI, to support the Global Dragonfly Assessment (GDA). I continue to do systematic, phylogenetic, biogeographic and ecological research on Odonata, especially of Palaeotropical Zygoptera as part of the DAWN working group (Damselfly Workers Naturalis), and lecture on these subjects for Leiden University.

Books and journals

I published an English fieldguide to European Odonata with Richard Lewington in July 2006 (see sample); French and Dutch editions appeared in 2007 and 2008. I was co-editor and co-author of the handbook of Dutch Odonata (1998-2002) and co-founded the Dutch society for odonatology (NVL) in 1997, being editor-in-chief of its journal (Brachytron) until 2001. Since 2007 I am an editor of the ISI-listed International Journal of Odonatology (IJO) and since 2009 of Tijdschrift voor Entomologie.

Congo 2010

In April-June 2010 I participated in the Congo 2010 expedition. Watch me catch dragonflies while we seek a 'hidden lake' on the Belgian TV news (Dutch), listen to the interview on Dutch national Radio 1 (Dutch; starts at 09:30), or read the articles in Le Vif/L'Express Magazine (French) about the expedition and in De Volkskrant (Dutch) about my involvement, both with photographs by Kris Pannecoucke.
