Broken equipment and creative solutions – second field season in Borneo

The MountBuzz Borneo team 2026 consisted of Andrea Errante – his third trip within the MountBuzz project now! – Julian Gericke, Isabella Fresner and Hong Chen. They were further accompanied by PAIn lab member Ben Lazarus, who introduced the team to artificial vibration experiments and single visit experiments with bees. The team was lucky in finding many species in flower, but unlucky with equipment failure. The air particle counters we use for pollen counting stopped working – despite having worked perfectly fine when tested the day before departure in the lab. The team readjusted the fieldwork plan somewhat, decided to use an alternative method for pollen collection (in Eppendorf tubes) and further refined the single visit experiments test stand! Julian in particular turned out to be a bee whisperer and just recently surpassed the 200th single bee visit, for which he also obtained accurate bee size measurements and audio recordings! Another great surprise for the team waited at one of our lower elevation sites – while in 2025, the team could only locate a single species in flower (Melastoma malabathricum), this time, they found three other species in full flower, covering tribes that we had not sampled previously! Discoveries like those show how valuable it is for us to go back to the same field sites at different times, because they might hold treasures previously unnoticed! Congratulations to the whole team for working through many challenges and keeping up the spirit!
