| rapid sexual maturity and short life span in the blue-legged frog and the rainbow frog from the arid isalo massif, southern-central madagascar. | longevity and age at sexual maturity were estimated in two anurans from the arid isalo massif (southern-central madagascar), the blue-legged frog (mantella expectata) and the rainbow frog (scaphiophryne gottlebei). phalanges from 69 individuals of m. expectata and 38 individuals of s. gottlebei were analyzed, using the skeletochronological method, in samples collected during two periods: january-february and november-december 2004. the male gonads of both species were also analyzed in order to b ... | 2010 | 21051209 |
| first record of viviparity in polystomatid flatworms (monogenea: polystomatidae) with the description of two new species of madapolystoma from the madagascan anuran hosts blommersia domerguei and mantella expectata. | two frog species, blommersia domerguei and mantella expectata, are reported as hosts for new species of madapolystoma. phylogenetic analyses and genetic divergences observed in the genus supported the distinction of two morphotypes infesting selectively each host species and morphological investigation combining marginal hooklet morphometrics, genital spine number and measurements further showed that polystomes from the two host species differed from each other and from all other known polystome ... | 2018 | 30258781 |
