Biodiversity of insects is threatened worldwide. Here, we present a comprehensive review of 73 historical reports of insect declines from across the globe, and systematically assess the underlying drivers. Our work reveals dramatic rates of decline that may lead to the extinction of 40% of the world’s insect species over the next few decades. […] The main drivers of species declines appear to be in order of importance: i) habitat loss and conversion to intensive agriculture and urbanisation; ii) pollution, mainly that by synthetic pesticides and fertilisers; iii) biological factors, including pathogens and introduced species; and iv) climate change
Cuckoos, spotted flycatchers, fieldfares, hobbies, woodlarks, skylarks, lapwings, house sparrows, lesser spotted woodpeckers, yellowhammers, woodcock, red kites, sparrowhawks, peregrine falcons, all five types of British owl, the first ravens at Knepp in the past 100 years — the list goes on and on. The speed at which all these species — and many more — have appeared has astonished observers, particularly as our intensively farmed land was, biologically speaking, in dire condition in 2001, at the start of the project. The key to Knepp’s extraordinary success? It’s about surrendering all preconceptions, and simply observing what happens. By contrast, conventional conservation tends to be about targets and control, and often involves micro-managing a habitat for the perceived benefit of several chosen species.
Syria’s civil war has prompted the first withdrawal of seeds from a “doomsday” vault built in an Arctic mountainside to safeguard global food supplies, officials said on Monday. The seeds, including samples of wheat, barley and grasses suited to dry regions, have been requested by researchers elsewhere in the Middle East to replace seeds in a gene bank near the Syrian city of Aleppo that has been damaged by the war. “Protecting the world’s biodiversity in this manner is precisely the purpose of the Svalbard Global Seed Vault,” said Brian Lainoff, a spokesman for the Crop Trust, which runs the underground storage on a Norwegian island 1,300 km (800 miles) from the North Pole.
In many parts of the developing world, students face barriers to access academic materials. Libraries are often inadequate, and schools and universities are often unable to pay dues for expensive, specialized databases. For these students, the Internet is a vital tool and resource to access materials that are otherwise unavailable to them. Yet despite the opportunities enabled by the Internet, there are still major risks to accessing and sharing academic resources online. A current situation in Colombia exemplifies this problem: a graduate student is facing four to eight years in prison for sharing an academic article on the Internet. He wasn’t making a personal profit from sharing the article—he simply intended for other scientists like him to be able to access and cite this scientific research.
