Free as a bird?It may seem like birds have the freedom to fly wherever they like, but scientists at the University of Missouri have shown that what's on the ground has a great effect on where a bird flies. This information could be used by foresters and urban planners to improve bird habitats that would help maintain strong bird populations.

Complex interactions keep pests under controlProponents of organic farming often speak of nature's balance in ways that sound almost spiritual, prompting criticism that their views are unscientific and naïve. At the other end of the spectrum are those who see farms as battlefields where insect pests and plant diseases must be vanquished with the magic bullets of modern agriculture: pesticides, fungicides and the like.

Ants use multiple antibiotics as weed killersResearch led by Dr Matt Hutchings and published recently in the journal BMC Biology shows that ants use the antibiotics to inhibit the growth of unwanted fungi and bacteria in their fungus cultures which they use to feed their larvae and queen.
These antibiotics are produced by actinomycete bacteria that live on the ants in a mutual symbiosis.
