Variations in salinity tolerance in the Pacific Treefrog, Hyla regilla, in OregonRoberts, James Oliver 28 April 1970 (has links)
Eggs, larvae and adults of the four subspecies of Hy la regilla
occurring in Oregon as given by Jameson, Mackey and Richmond
(1966) were collected and subjected to salt stress in a series of
graded seawaters.
It was found that in all cases adults were more tolerant than
larvae and larvae were more tolerant than eggs. It was also found
that animals in all stages taken from the area extending westward
from the crest of the Oregon Coast Range to the sea, designated
as the range of Hy la regilla pacifica, were more tolerant of elevated
salt levels in their ambient medium than animals from the three
other subspecies areas in Oregon.
Observations were made of the effect of elevated salinities on
the eggs and the development of the embryos with respect to the
vitelline membranes, the closure of the blastopore and neurulation.
Mechanisms were postulated to explain the observed differences
in tolerance to salt stress. / Graduation date: 1970
