Bumblebee-bothering, pollen-pilfering honey bees
Flowers and insects have a long history of coevolution. Insects as pollinators are rewarded with nectar and pollen. Some bees exploit this and engage in nectar robbery. Honey bees in Italy have been observed stealing pollen from bumblebees, contributing to a range of pollen-gathering behaviors. Honey robbery from hives by…

Pollutants and pollination, a radical view
The post discusses the impact of nitrogen trioxide (NO3) on plant-pollinator interactions. NO3 disrupts floral scents, affecting insect foraging and pollination. This has far-reaching implications for global food crops and natural ecosystems. Research suggests that human intervention and cultivation practices can potentially offset the negative effects. However, addressing the root…

Under-appreciated plant parts: The grass ligule
The post describes the author’s research on the grass ligule, focusing on its anatomical and functional complexity, including the passive exclusion of water and spores, and the potential active role in synthesizing and secreting a lubricating substance. The ligule’s surprising cellular complexity and potential photosynthetic function are also explored. The…

Seed dispersal, on a wing and a prayer…
The post considers the work of Rubén Torices et al. on the role of “wings” on fruits of Anacyclus clavatus which challenges the assumption that they aid in dispersal by wind. Results show that the “wings” actually accelerate germination by aiding water absorption. Torices et al’s paper demonstrates clear experimental…

Plants and people – and pharmaceuticals…
This post discusses the potential pharmaceutical uses of four plants – marijuana, navy beans, thunder-god vine, and willow. It explores their impact on weight gain, weight loss, cancer prevention, and killing viruses. Specifically, it delves into the effects of marijuana on appetite, celastrol’s weight-loss potential, navy beans’ impact on gut…
