In this free course, Surviving the winter, we study one aspect of the fluctuating nature of an organisms environment. We consider how organisms living in a temperate climate, such as that in Britain, are adapted to cope with winter. You will see that there is much diversity of adaptations among organisms, with different species coping with the demands of a fluctuating environment in quite different ways. As cyclic variations are a widespread feature of environments, the range of adaptations to them is an important source of biological diversity.
The total area of garden space in the UK is probably greater than that of all the nation's nature reserves. Converting just a small section of your garden into a breeding place for birds can make a small but significant contribution to the survival of bird species.
Fifty years ago [March 1967] the Torrey Canyon ran aground between Cornwall and the Isles Of Scilly, splilling over 100 million litres of crude oil into the sea. To mark the anniversary, we're reproducing an article from WWT's Wildfowl magazine, where Dr J V Beer explains how the RSPCA and WWT tried to rehabilitate wildlife caught in the disaster.
Bird ringing is a world-wide method of finding out where birds migrate and how population levels change. This video shows how it works in Bog Meadows, a city nature reserve a few metres from the M1 motorway in Northern Ireland.
