Arnold Cooke is well known to many in the herpetological world. Both a prominent professional ecologist, and a highly-regarded amphibian specialist, he has worked with amphibians for many years. Most famously he has conducted the UK's longest-standing study of common toads and the effect of road mortality on their populations. 

The current hot weather is making reptiles difficult to spot. In hot weather, reptiles don't need to spend much time basking, and we lose our best chance of seeing them.

Numbers of Britain’s rarest lizard, the sand lizard, are increasing in parts of southern England - possibly due to climate change.

Researchers are investigating adder populations in southern England to see if they are suffering from genetic bottlenecking. This can occur when populations become too small, and low gene flow means they are not enriched by sharing of mutations between numerous individuals.
