Today we have the pleasure of bringing you a unique interview with Marc van Roosmalen which illustrates his situation and problems as he sees them. For those of you who aren’t familiar with who Marc van Roosmalen is, what he has done, and his present situation, I recommend reading this short introduction before reading the interview.

Thanks for taking the time to answer our questions Marc!

You have discovered a number of different species. Was finding one of them more special than finding the others? Is it still as much fun to find new species as it was when you found your first new species?

Marc G.M. van Roosmalen (MGMvR): Most fun but also most time and energy consuming for me was finding the ‘Land of Dermis’, where the relatives of Dermis occur – the baby black-capped dwarf marmoset that was delivered on my Manaus doorstep April 1996. With decades of experience in keeping all kinds of primates in halfway houses I knew right away that Dermis represented a new species of monkey and, undoubtedly, also a new primate genus. That event instantly took away the scepsis in me as a primatologist that nowadays it would be impossible to find new species of primates hitherto unknown to science. The quest that followed to find the monkey’s distribution somewhere in the huge Rio Madeira Basin had me stumbling into a Conan Doyle type of ‘Lost World’ – the Rio Aripuanã Basin – a hotspot of biodiversity that I soon recognized to be a totally new ecosystem within Amazonia, whose fauna and flora had never before been inventoried by naturalists, animal collectors, botanists and ornithologists alike. It took me a number of boat surveys to find Callibella humilis, a needle in a haystack as big as France. During innumerable surveys of the local rainforest and through interviews with the locals showing pictures of Dermis I happened to identify at least five other hitherto undescribed primates in the area.

Other highly memorable discoveries were those of some large terrestrial mammals whose existence I did not know of until I had close encounters with them while hiking alone through the forest. First spotting of a giant peccary (Pecari maximus) family silently crossing my trail while I was watching a group of Gray sakis in the canopy, or a group of dwarf peccaries (Pecari?) bumping literally into my feet while chasing one another through the undergrowth. And, back in camp, asking the locals what the hell the creature was that I had come upon that day…

Nowadays, under the Lula regime, it is not so much fun anymore to find new species because you run the risk to get caught in the ‘criminal’ act of collecting and transporting living evidence to support the validity of your find. To be able to publish it in a peer reviewed scientific journal you need at least to collect and deposit holotype material in a Brazilian museum. Without the proper collecting permits – a federal “license to kill” you can apply for in Brasilia, but never get granted – you seriously run the risk to be thrown in jail on accusation of what officials in Brazil call “biopiracy”. That is when you – like me – still collect, transport or keep alive any biological sample that could serve as holotype material or for DNA analysis in order to determine the phylogenetic and taxonomic status of your find. This way they make it impossible for Brazilian as well as foreign scientists to carry out biodiversity studies so needed for a sound nature conservation policy.

What do you feel when you finally find a species you have been looking for during a long time?

MGMvR: In the field you really feel yourself catapulted back in time, following the footsteps of the great naturalists such as Alexander von Humboldt, Wallace, Bates, Spruce, Spix & Martius. Little progress has been made in the Brazilian Amazon ever since my natural-history heroes collected and described a large part of the Amazonian flora and fauna. In this euphoria one tends to forget that times have changed. That having the great privilege to pick up the thread these icons left behind some 150-200 years ago is now considered a ‘criminal act against nature’.
