碩士 === 東海大學 === 生命科學系 === 96 === Theories of parental care predict that paternity is an important factor
affecting the amount of parental care a male provides. A male should
reduce parental care when his certainty of paternity in the brood is low.
The purpose of this study was to investigate the relationship between
certainty of paternity and parental care in a treefrog, Kurixalus eiffingeri.
I used microsatellite markers to analyze genetic relationship of 29 egg
clutches and males in the nests. Most males appeared in the nest were
genetic father of all or part of the egg clutchs. Twenty-five clutches were
cared by male frogs, 24 of them had one attending male, and one was
attended by two males. Multi-male mating occurred in 21.74% of the
matings. Two males in a multi-male mating fertilized eggs and resulted in
multiple paternity. Amplexing males did not necessarily sire more eggs
than peripheral males but the larger males had more offspring. Male K.
eiffingeri attended eggs at a relative low frequency. Attendance and
brooding frequency were higher in the early than late embryonic stage.
Attendance and brooding time were positively correlated with clutch size
but not male weight. Compared to males in single male mating, males
participated in multi-male mating provided significantly low levels of
attendance and brooding. The presence of other males during egg laying
process may act as a cue of reduced paternity which affects a males’
willingness to care their embryos.
