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.

Laying Froggo?
Male Common frogs (Rana temporaria) clasp the female, whilst mating. It was thought that the females had little choice in the matter. A recent study has now shown, however, they can employ a number of techniques to avoid unwanted clasping. Females can twist their bodies or even 'play dead' (show 'tonic immobility'). 'Playing dead' is a strategy particularly used by smaller females (https://www.theguardian.com/science/2023/oct/11/female-frogs-fake-death-unwanted-advances-study). Although 'playing dead' may seem a little extreme, mass clasping can endanger the lives of female frogs.
