New research from China shows how the loss of insects is destabilising food webs.
Tinkering around the margins of English farms won’t benefit biodiversity, research suggests.
DDT accumulates in wildlife and magnifies up the food chain. Birds of prey occupy the top of these food chains in various ecosystems.
Over hundreds of million years of evolution, ants have come up with some pretty smart solutions to problems of agriculture, navigation and architecture. People could learn a thing or two.
The report results could help explain honeybee colony deaths.
Seventy-two per cent of native bumblebee species in North America are cutting their winter hibernation short by timing their emergence to earlier spring onsets.
Honey bees, wild and native bees face threats from parasites, pesticides and habitat loss. Shorter winters, more extreme weather and more habitat destruction won’t help.
Published in 1962, ‘Silent Spring’ called attention to collateral damage from widespread use of synthetic pesticides. Many problems the book anticipated persist today in new forms.
Farmers who use little or no fertiliser can use ecological practices to increase their yields.
The new State of the Environment report shows Australia’s soil and the life it holds is in poor condition. We need to protect our underground biodiversity.
The iconic monarch butterfly has been added to the Red List of endangered species, but hasn’t received protection in the US yet. That’s not necessarily a bad thing.
Cowpea is an important crop in Ghana. What will a genetically modified version mean for the country’s farmers?
Bed bugs are pretty much universally reviled. But a public health entomologist explains how – while potentially traumatizing to deal with – they aren’t likely to make you sick.
Cleaning up the Great Lakes was a big job when the US and Canada undertook it in 1972. Today it’s far more challenging.
There is abundant evidence of the involvement of endocrine disruptors in reproductive dysfunction in several species, including humans.
Studies suggest that seeds coated with neonicotinoid insecticides may harm nontarget insects, mammals and birds. In response, states are starting to restrict use of these products.
The insecticide Bti kills target organisms like mosquitoes and blackflies, but new research shows it may also have negative effects on non-target species like frogs.
Farmers are stuck in a chemical war against weeds, which have developed resistance to many widely used herbicides. Seed companies’ answer – using more varied herbicides – is causing new problems.
The production and release of synthetic chemicals worldwide is destabilising the Earth system.
