Unleash your Inner Ninja with Africa’s Largest Inflatable Obstacle Course these…A new study analyzed pollen from 57 North American plant species, identifying those most nutritionally beneficial for bees, which could inform conservation efforts and wildflower restoration projects.
With many bee species facing significant threats, the researchers say they hope these findings can inform conservation efforts from policy changes to individual actions like planting native flowers and reducing pesticide use. When foraging, bees collect pollen using specialized structures on their bodies, such as pollen baskets on their hind legs, or scopal hairs on their abdomen or legs, depending on the species. They then bring this pollen back to the hive or nest.
The study found that bees require a diverse diet from multiple plant sources to obtain a balanced intake of fatty acids and essential amino acids. No single plant species provided pollen with an optimal nutritional profile. The researchers also examined protein-to-lipid ratios and omega-6 to omega-3 fatty acid ratios in the pollen samples, as these are considered important factors in bee nutrition. They found wide variation between species, even within the same plant genus.
Rehan and her colleagues say they hope their findings will help inform the selection of plant species for pollinator gardens and habitat restoration efforts. However, they caution that the analysis only looked at 57 plant species out of thousands that exist.
