(University of Vienna) The first flowering plants originated more than 140 million years ago in the early Cretaceous. They are the most diverse plant group on Earth with more than 300,000 species. In a new study in Communications Biology, evolutionary biologists around Agnes Dellinger and Jürg Schönenberger from the University of Vienna have analysed 3-dimensional models of flowers and found that flower shapes can evolve in a modular manner in adaptation to distinct pollinators.

Bees need water just like the rest of us. A honeybee might fly several miles to find a good water source, both for drinking and to help regulate the temperature of her hive. Sometimes, though, a thirsty honeybee gets more…
Scientists placed honey bee hives next to soybean fields in Iowa and tracked how the bees fared over the growing season. To their surprise, the bees did well for much of the summer. The colonies thrived and gained weight. But in August, the trend reversed. By mid-October, most of the honey was gone and the overwintering brood was malnourished, the team discovered. Placing the hives near restored prairies late in the season rescued them.
