  1. Translocate frogs

    A before-and-after study in 1999 on an alpine fell in Kings Canyon National Park, California, USA (Matthews 2003) found that translocated mountain yellow-legged frogs Rana muscosa lost weight during the 30 days after translocation. Translocated frogs lost an average 1.2 g in body mass, whereas resident frogs gained 2.5 g over the same period. Seven of the translocated frogs returned to their original capture site, five moved the 206–485 m in 11–30 days. Four frogs moved in the direction of their capture site and nine remained at the translocation site. Twenty frogs with transmitters fitted were translocated 144–630 m to other ponds and lakes that were not typically used. Frogs were monitored intensively for 30 days in August and then surveyed using passive integrated transponder (PIT) tags. Translocated and 18 randomly selected resident frogs were weighed at the start and end of the study.
