Dr. Alex Smith, an Associate Professor in the Department of Integrative Biology at the University of Guelph, spent his summer crawling around the leaf litter of forests in northwestern Costa Rica to study insects. 

He wanted to understand how the smallest and most diverse animals are affected by climate change, especially as mountain peaks once covered in almost permanent cloud and mist, are now experiencing warmer and drier conditions.

What he found was that the rise in temperature is causing insect communities along the mountain to move up, threatening communities near the top of the mountain with more competition and predators. 

The long-term trend, according to Smith, is a drop in insect biodiversity and abundance on the mountain.

Besides the research work, Smith recounts one harrowing encounter in the forest when he came face to face with a viper that hid under his equipment. The venomous snake hissed and lunged at him, but missed by only a few centimetres luckily because it had become tangled in the straps of his equipment.  

Smith said he won't venture into the rainforests of Costa Rica again, without snake antivenom and snake-proof boots.
