Tropical Snake Occurrences

Motivated by a frustration at the lack of snake occurrence data for snakes in Thailand, we investigated how openly accessible social media data could fill the gaps. Ultimately, we revealed that the vast majority of snake occurrence data comes from non-tropical regions, and that social media is currently insufficient to make up for that bias in the tropics... for now.

King Cobra Research

The results of a multi-year radio tracking effort of king cobras. We managed to quantify the size of their home ranges, habitat use and the threats they face. We found considerable breeding season shifts in some male's home range and one showed a change in the habitats used, making greater use of anthropogenic areas. The anthropogenic areas appear to be riskier for king cobras to live in.

Toxic Toads in Madagascar

My masters work aimed to unearth whether the newly introduced toxic toad, Duttaphrynus melanostictus, was liable to poison the native fauna of Madagascar. The toxics of this toad bind to one specific area, and by sequencing that area we are able to discern a species' vulnerability to the toxics. The findings have been published in Current Biology.
