| batrachochytrium dendrobatidis in amphibians confiscated from illegal wildlife trade and used in an ex situ breeding program in brazil. | this paper describes an outbreak of chytridiomycosis affecting a group of dendrobates tinctorius, a neotropical anuran species, confiscated from the illegal wildlife trade and housed in a private zoo in brazil as part of an ex situ breeding program. we examined histological sections of the skin of 30 d. tinctorius and 20 adelphobates galactonotus individuals. twenty d. tinctorius (66.7%) and none of the a. galactonotus were positive for batrachochytrium dendrobatidis (bd). multiple development s ... | 2012 | 22436465 |
| two new species of rhabdias stiles et hassall, 1905 (nematoda: rhabdiasidae) from anuran amphibians in pará, brazil. | two new lung-dwelling nematode species of the genus rhabdias stiles et hassall, 1905 were discovered in caxiuanã national forest, pará state, brazil. rhabdias galactonoti sp. n. was found in a dendrobatid frog adelphobates galactonotus (steindachner). the species is characterised by the regularly folded inner surface of the anterior part of the buccal capsule seen in apical view, flask-shaped oesophageal bulb and narrow, elongated tail. rhabdias stenocephala sp. n. from two species of leptodacty ... | 2016 | 27189518 |
| the evolution of polymorphism in the warning coloration of the amazonian poison frog adelphobates galactonotus. | while intraspecific variation in aposematic signals can be selected for by different predatory responses, their evolution is also contingent on other processes shaping genetic variation. we evaluate the relative contributions of selection, geographic isolation, and random genetic drift to the evolution of aposematic color polymorphism in the poison frog adelphobates galactonotus, distributed throughout eastern brazilian amazonia. dorsal coloration was measured for 111 individuals and genetic dat ... | 2020 | 31712747 |
| the tadpole of adelphobates galactonotus (steindachner, 1864) (amphibia, anura, dendrobatidae). | the systematics of the dart-poison frogs, family dendrobatidae, experienced several taxonomic rearrangements over time (e.g., grant et al. 2006, 2017; brown et al. 2011). currently, this family comprises 194 described species organized in three sub-families and 15 genera (frost 2018). among them, the genus adelphobates grant, frost, caldwell, gagliardo, haddad, kok, means, noonan, schargel, wheeler, 2006, comprises three species, all distributed in central and lower amazon drainage of peru and b ... | 2018 | 30313506 |
