    Sequencing pollen DNA to discover insect migratory routes

    Metabarcoding, a technique of mass DNA sequencing, allows for tracing migratory routes of insects. A small DNA fragment of the pollen that insects transport is used as a barcode to identify the plant species they visited previously.

    Young aphids piggyback on adult aphids to get to safety faster

    Young aphids piggyback on adult aphids to get to safety faster

    Following escape from plants being grazed on by animals, researchers noticed young aphids mounting the backs of adult aphids and "catching a ride," which allowed them to reach the safety of a new plant faster.

    New and Easy Marking Method Tracks Bees Without Killing Them

    New and Easy Marking Method Tracks Bees Without Killing Them

    A wide range of bees play an important role in pollinating everything from wildflowers to agricultural crops. Scientists have long sought a cheap and easy way to track released bees, but so far it's been an uphill battle. A new study outlines a new technique that quickly, simply, and inexpensively marks bees--and it's non-lethal, too.

    Mixing It Up: Mixed-Crop Fields Can Boost Natural Biocontrol of Insect Pests

    Modern intensive agriculture, with its vast monoculture fields of cash crops, may seem rich in terms of yields and profits, but to an ecologist's eye these fields are rather poor. In terms of biodiversity, they are downright impoverished.

    Genetic behavior reveals cause of death in poplars essential to ecosystems, industry

    Scientists studying a valuable, but vulnerable, species of poplar have identified the genetic mechanism responsible for the species' inability to resist a pervasive and deadly disease. Their finding could lead to more successful hybrid poplar varieties for increased biofuels and forestry production and protect native trees against infection.
