A pоpulаtiоn оf frogs wаs reduced 60 yeаrs ago by a major outbreak of a disease. The population was reduced to a very small size (less than 300 individuals) and the frequency of mating with relatives increased. Recently, this population has been observed to have morphological defects and reduced survivorship. There has also been a reduction in fecundity. As a result the population is becoming smaller and smaller. What is happening to this population and how could it be helped?
