Is the
presence of open grassy or at least
open ground a factor in distribution
of Triturus? During this side trip noted
a few amplexing pairs of Triturus, all
in shallow water, one pair almost
entirely out of water. Unpaired ?♂ also
present. Noted perhaps 8-10 animals.
Recaptured #69b, a R. boylii originally
marked in pool beneath drain pipes
above area. How did it get so far down-
stream? Or did it only move upstream
to pool beneath drain pipes because
it was only remaining pool & water
in fall months? In area itself
Triturus
captured 3 new ?♀, all at one spot
and 3 ?♂, all at one spot. One ?♂
a recapture from January. This animal,
#88, in same spot originally marked
in spite of several severe floodings,
and flushings of stream since first
marked. Do animals leave water
when such flushings occur or do
quiet pools always exist for retreating
into? Two juveniles also taken. None
of ?♂ completely pigmented for breeding
yet within area of study. Obviously
season here is later than at Trafayette.
