Trial and error in the Highlands

Article Abstract:

Scotland's red deer demonstrate the importance of controlling deer populations to prevent ecological deterioration. In Scotland, as in the Northern Hemisphere generally, deer have increased substantially in number in recent decades. This increase has brought on ecological problems such as degradation of habitat, damage to forests and the spread of arthropod-borne diseases. In response the Red Deer Commission recommended a 30% cut in hind totals through hunting. However, hunters' preference for killing male rather than female deer poses a problem.

Red deer stocks in the highlands of Scotland

Article Abstract:

The need for environmental benefits in reducing number of deer and the number of hill sheep in many parts of the Highlands of Scotland to prevent the heather cover and trees from getting diminished. The measures undertaken by the World Wildlife Fund and the Royal Society for the Protection of Birds to protect the environment of the Scottish Highlands is presented.

Noise and determinism in synchronized sheep dynamics

Article Abstract:

A nonlinear time-series model has been devised to describe environmental correlation in synchronized sheep populations. Evidence suggests that population synchronization is affected by environmental correlation. Sheep count samples were taken from sheep populations on two islands from the St Kilda archipelago. Autoregressive analysis data is illustrated.
