A field experiment about larval
density regulation in frogs. The pond is
divided by a plastic, tadpole proof fence. Spawn is redistributed
to create high and low (tadpoles) density sections
and the performance of the tadpoles monitored 1990 to 1997. Some
results are available in report #18.
A field experiment about adult
density regulation in frogs. Four 30*30 m areas are fenced in on a
moist meadow. Adult frog density was manipulatied in these during four
summers and the effect on frog growth monitored. The study is not yet
