Disturbing news (http://www.guardian.co.uk/environment/2008/nov/10/conservation-fishing) that many of the sharks and rays found off UK shores are facing extinction. One of their problems is that (unlike most boney Teleost fish) these ancient vertebrates only produce relatively few offspring (they are 'K' strategists). This means that taking them in numbers (for 'sport' or as food items such as skate wings or rock salmon) generally leads to dramatic declines in these top predators.
This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.
