Climate change is the top threat to pollinators like bees and butterflies, crucial for biodiversity and food security, according to a new review paper. The study highlights how climate-induced habitat changes and human activities harm pollinators, urging integrated conservation strategies to mitigate these impacts and safeguard our food systems.
Around the world, honeybees are dying in large numbers. This die-off is in part because of a deadly virus that can kill bees or impair their ability to return to the hives after foraging. But researchers now show that a cheap and naturally occurring chemical compound could prevent or reverse the effects of the virus in bees.
The global decline of pollinators threatens the reproductive success of 90 per cent of all wild plants globally and the yield of 85 per cent of the world’s most important crops. Pollinators – mainly bees and other insects – contribute to 35 per cent of the world’s food production. The service provided by pollinators is particularly important for securing food produced by the more than two billion small farmers worldwide.
From pollen forecasting, honey analysis and climate-related changes in plant-pollinator interactions, analysing pollen plays an important role in many areas of research. Microscopy is still the gold standard, but it is very time consuming and requires considerable expertise. Scientists have now developed a method that allows them to efficiently automate the process of pollen analysis.
Researchers have discovered a new role for a well-known plant molecule, providing the first clear example of ACC acting as a likely plant hormone. Researchers show that ACC has a critical role in pollination and seed production by activating proteins similar to those in human and animal nervous systems. Findings could change textbooks and open the door for research to improve plant health and crop yield.
Producing fewer sperm cells can be advantageous in self-fertilizing plants. An international study has identified a gene in the model plant Arabidopsis that reduces the number of pollen. In addition to supporting the evolutionary theory, these findings could help to optimize plant breeding and domestication in agriculture.
In a world first, researchers have discovered a plant that has successfully evolved to use ants—as well as native bees—as pollinating agents by overcoming their antimicrobial defenses.
Over 80% of the world’s flowering plants must reproduce in order to produce new flowers, according to the U.S. Forest Service. This process involves the transfer of pollen between plants by wind, water or insects called pollinators — including bumblebees. In a new study, researchers discovered a spiny pollen that has evolved to attach to traveling bumblebees.
Unless it happens to be allergy season, most people don’t give a lot of thought to pollen. But new research might change the way we look at a field of flowers. A study suggests that pollen color can evolve independently from flower traits, and that plant species maintain both light and dark pollen because each offers distinct survival advantages.
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 evolutionary biologists have analysed 3-dimensional models of flowers and found that flower shapes can evolve in a modular manner in adaptation to distinct pollinators.
