Disease threat may change how frogs mate
Date:7/27/2009

Dr Amber Teacher, studying a post-doctorate at Royal Holloway, University of London, has discovered evidence that a disease may be causing a behavioural change in frogs. The research, published in the August edition of Molecular Ecology, has unearthed a surprising fact about our long-tongued friends: wild frogs in the UK may be changing their mating behaviour.

Dr Teacher conducted her research with colleagues from the Institute of Zoology and Queen Mary, University of London. The research followed concerns over the survival of wild frog populations in the UK. Ranavirus, which had its first reported case in England in the early 1980s, is one of many pathogens ravaging the amphibian community.

Dr Teacher's pioneering new research looks at the genetic make-up of populations, and indicates that wild frog populations that have been infected with this virus may be choosing mates differently to those in healthy populations.

As Ranavirus is typically associated with heavy death tolls in infected populations, there are often few frogs left alive to mate. This frequently leads to inbreeding, which causes an increase in relatedness in the population. However, Dr Teacher has uncovered startling results; finding that despite inbreeding there has been no subsequent increase in relatedness in these populations.

Dr Teacher's conclusion is that this lack of relatedness has been caused by a change in the frogs' mating strategy. With diseased frogs struggling to mate, healthy frogs are likely to be mating more often with other healthy frogs, leaving diseased frogs to mate with each other. These frogs could also be selecting mates based on their Major Histocompatibility Complex (MHC) type; a group of genes directly involved with the animal's immune system. As the common frog is generally thought to mate randomly, this is a major shift in the frogs' mating behaviour.

Active mate choice based on MHC type is not uncommon in other sp
