Treefrog eggs help

A new postdoc here at UCSB is studying the effects of Bd in tadpoles, and so is in need of about 20 clutches worth of freshly-laid Pseudacris regilla eggs. Treefrogs are really done with it at low elevations here, so I agreed to post a request for help on her behalf. If you have a place where they a...

Re: Arroyo Toad ID Confirmation.

Trout don't seem to affect arroyo toads much, although trout fishermen do. Long ago (pre-listing) I sat and flipped tadpoles to foraging trout, and the fish ignored them. Sunfish in the daytime and bullheads by night, and sculpins any time all enjoy toad tadpoles, but trout seem to be in the clear. ...
