Mentally “exhausted” honey bees—petroleum exhaust makes bees learn slower and forget faster

Scent pollution from exhaust fumes could disrupt the relationship between honey bees and the flowers they feed from and pollinate. The smell of flowers invites pollinators to come and feast on their nectar. But exhaust masks those smells, making it harder for bees to learn and remember the floral scents that cue them in to flowers.

The global buzz: A call to restore insect biodiversity

Insects are in decline worldwide. Without a rethinking of current agricultural practices and a bucking of trends in urbanization, biodiversity of insects is threatened globally. Insects are the structural and functional base – the linchpin – of all ecosystems. We are part of those ecosystems. Unlike the vastness of climate change and its many aspects, the solutions to the problem of insect declines are readily available. With proper perspective, appreciation, and respect for the roles insects play in ecosystem integrity, human health, and economic markets, we can reverse course.

Who are we going to call when rainforests are suffering from droughts? Termites!

Tropical rainforests are already showing signs that climate change is leading to higher tree mortality. However, Dr. Louise A. Ashton and collaborators investigated if termites could help turn the game on climate change and help tropical biodiversity and survival. This fascinating study shows that high termite abundance can lead to greater soil moisture and nutrient levels during drought conditions, which ultimately favors plant establishment. This suggests termites can potentially be major allies of tropical forests against climate change.
