Plant-insect ecologists typically attribute the differences to variation in the nutritional quality or defective chemistry of plant tissues. However, the researchers found that cactus-feeding insects chose host plants based on how the plants allocated resources between growth and reproduction.
"The crux of our findings is actually quite intuitive", says Miller. "These insects prefer to feed on flowers, so it's not terribly surprising that they are abundant on cacti that invest most of their resources in flowers."
"What was surprising," Miller adds, "was how one single trait predicted the variation"
The results also have implications for understanding the evolution of plant allocation strategies. Current thinking on the subject says that these strategies are a trade-off between current reproduction and future survival. The finding that plant reproductive allocation can attract enemies means that sex may be even more costly than previously though. This research also has implications for weed control and protection of rare plant species.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
