A controversial agricultural insecticide that has been implicated in the collapse of bee colonies around the world also appears to be causing bird populations to drop, according to a new study. The insecticides known as neonicotinoids are designed to attack the central nervous system of insects that devour crops, but only about 5 percent of the chemical compound stays on the plant. The rest leaches into the soil and water, where it does its magic on other bugs, the researchers said.
Honey bees rented to out pollinate crops from apples to watermelons return to their hives with pollen containing an array of agricultural chemicals that make the insects more vulnerable to infection by a lethal parasite, according to a new study.
While other research has shown certain pesticides, including insecticides known as neonicotinoids and others used to fight parasitic mites, can compromise bee health, the new study shines a light on the impact of sprays used to kill fungi and molds.
When a woman walks into a male-crowded bar she’s unlikely to be showered with courtly attention — that is if findings about mating in the animal kingdom translate to the human realm.
“She might just be watching them fight it out and then have one particularly possessive one making sure others aren’t getting access to her,” Laura Weir, a postdoctoral fellow at Simon Fraser University in British Columbia, Canada, told me today.
In other words, as the dudes duke it out with each other, one little weasel will sneak over and trap her in a corner and try to keep her all to himself?
“Exactly,” she said, although she stressed her reluctance to take the analogy too far. The data, she noted, is compiled from the mating behaviors of the birds and bees … and alligators, fish, frogs, lizards and lobsters, too.
What appears to be part of a spring wedding bouquet is actually a nest for a rare species of solitary bee, a new study says.
Called a “flower sandwich,” the three-tiered arrangement consists of a thin layer of petals on the outside, then a layer of mud, and finally another layer of petals lining the inside of the chamber, according to study leader Jerome Rozen, a curator of invertebrate zoology at the American Museum of Natural History in New York.
At the core of the sandwich is the bee’s larva, which feasts on nectar and pollen deposited inside the chamber by its parent before the egg is laid and the nest is sealed.
A National Geographic grantee is pioneering the use of supersmall radio tracking tags that fit on the backs of bees, a technological breakthrough that may provide him and other scientists with a direct view of the pollinators’ flight patterns.
Parents may soon be telling their kids about the birds and the … birds.
Bees—and the flowers they pollinate—are disappearing, according to a new study of bee diversity. The results raise concerns about food crops and plant communities that rely on animal pollinators to reproduce.
Scientists compared a million records on bees from hundreds of sites in the United Kingdom and the Netherlands before and after 1980.
If Kimberly Russell’s vision pans out, the millions of acres of land that lie under electric power lines across the United States will come to life with the buzz of busy bees.
Russell studies insects and spiders at the American Museum of Natural History in New York. Her research shows that bees take refuge under power lines when utility companies allow the land there to grow shrubs and flowers.
