| the ecology of male egg attendance in an arboreal breeding frog, chirixalus eiffingeri (anura: rhacophoridae), from taiwan. | field observations were conducted on egg attendance in chirixalus eiffingeri from april to august 2003. parental attendance during embryonic development was performed exclusively by males. the frequency of egg attendance was low (27%), but it had a distinct diel pattern in which males were observed to attend eggs more frequently at night than during the day. attendance frequency significantly decreased with increasing developmental stage of the embryos, but it was not statistically significantly ... | 2007 | 17867842 |
| parentage of overlapping offspring of an arboreal-breeding frog with no nest defense: implications for nest site selection and reproductive strategy. | overlapping offspring occurs when eggs are laid in a nest containing offspring from earlier reproduction. earlier studies showed that the parentage is not always obvious due to difficulties in field observation and/or alternative breeding tactics. to unveil the parentage between overlapping offspring and parents is critical in understanding oviposition site selection and the reproductive strategies of parents. amplectant pairs of an arboreal-breeding frog, kurixalus eiffingeri, lay eggs in tadpo ... | 2015 | 25835716 |
| geological data indicate that the interpretation for the age-calibrated phylogeny for the kurixalus-genus frogs of south, south-east and east asia (lv et al., 2018) needs to be rethought. | recently, lv et al. (2018) published an age-calibrated phylogenetic tree for the kurixalus frogs, members of which occur across parts of south, south-east and east asia. a clade on taiwan, represented by kurixalus idiootocus and the kurixalus eiffingeri species complex, is deemed to have been resident since the middle cenozoic; its closest congeners are in southern indochina (not in the adjacent parts of south-east china), and the split between the two is dated at 32.8 ma. furthermore, a sub-pop ... | 2020 | 29448062 |
| the fatty acid composition of oophagous tadpoles (chirixalus eiffingeri) fed conspecific or chicken egg yolk. | we compared the lipid content and fatty acid composition of (1) the egg yolk of three anuran species (chirixalus eiffingeri, rhacophorus moltrechti and buergeria robustus) and chicken eggs; and (2) c. eiffingeri tadpoles fed conspecific eggs or chicken egg yolk. anuran and chicken egg yolk contained more non-polar than polar lipids but the proportions varied among species. chicken egg yolk contained low amounts of 22:5n-3 in the polar lipid fraction, and b. robustus eggs did not contain any n-3 ... | 2003 | 12781833 |
| testing the nest-homing abilities of a phytotelm-breeding frog, chirixalus eiffingeri (rhacophoridae). | we conducted a manipulative experiment to assess the homing of female chirixalus eiffingeri to the nest. there were three experimental treatments and a control. for the control treatment, bamboo stumps were cut off at the base and reattached. in the first experimental treatment, when stumps were displaced 1 m, the proportion of stumps attended by females and the growth of tadpoles did not differ from the results of the control treatment, suggesting the 1-m stump displacement did not affect the n ... | 2006 | 16849837 |
| the thermal environment of arboreal pools and its effects on the metabolism of the arboreal, oophagous tadpoles of a taiwanese tree frog, chirixalus eiffingeri (anura: rhacophoridae). | we have studied seasonal and diurnal fluctuations of water temperature in bamboo stumps and the effect of temperature on the energy metabolism of arboreal, oophagous tadpoles of chirixalus eiffingeri. we collected tadpoles (gosner stage 28-29) in february and august from chitou, taiwan and acclimated them to 12 and 22 degrees c. using a closed system, we measured tadpole oxygen consumption (v.o(2)) at 12, 17 and 22 degrees c. the water temperature was lowest in february (11-13 degrees c), increa ... | 2001 | 11423322 |
| water balance, growth, development, and survival of arboreal frog eggs (chirixalus eiffingeri, rhacophoridae): importance of egg distribution in bamboo stumps. | we studied the effects of substrate moisture and flooding on the arboreal eggs of chirixalus eiffingeri and determined the possible causes of egg mortality. eggs appear highly permeable to water vapor, losing 16.24% and 38.38% of initial egg mass in 2 h at 90% and 45% relative humidity, respectively. eggs that experienced positive water uptake developed faster, hatched earlier with larger hatchlings, and had greater hatching success than eggs that experienced negligible or negative water uptake. ... | 2019 | 9754530 |
| a molecular phylogenetic analysis of the family rhacophoridae with an emphasis on the asian and african genera. | using characters from mitochondrial dna to construct maximum parsimony and maximum likelihood trees, we performed a phylogenetic analysis on representative species of 14 genera: 12 that belong to the treefrog family rhacophoridae and two, amolops and rana, that are not rhacophorids. our results support a phylogenetic hypothesis that depicts a monophyletic family rhacophoridae. in this family, the malagasy genera aglyptodactylus, boophis, mantella, and mantidactylus form a well-supported sister c ... | 2002 | 12144761 |
| systematic revision of the taiwanese genus kurixalus members with a description of two new endemic species (anura, rhacophoridae). | two new species of rhacophorid tree frog were identified in taiwan. in both new taxa, derived reproductive characteristics of laying eggs in tree holes and oophagous tadpoles are shared with kurixalus eiffingeri, but they are divergent from each other in molecular genetics, mating calls, and tadpole and adult morphology. the morphological characteristics and the molecular phylogenetic evidence support the hypothesis that the two new species, kurixalus berylliniris sp. n. and kurixalus wangi sp. ... | 2016 | 26877703 |
