| sympatric lineages in the mantidactylus ambreensis complex of malagasy frogs originated allopatrically rather than by in-situ speciation. | madagascar's biota is characterized by a high degree of microendemism at different taxonomic levels, but how colonization and in-situ speciation contribute to the assembly of local species communities has rarely been studied on this island. here we analyze the phylogenetic relationships of riparian frogs of the mantidactylus ambreensis species complex, which is distributed in the north of madagascar and was originally described from montagne d'ambre, an isolated mountain of volcanic origin, curr ... | 2020 | 31809850 |
| 'barcode fishing' for archival dna from historical type material overcomes taxonomic hurdles, enabling the description of a new frog species. | taxonomic progress is often hindered by intrinsic factors, such as morphologically cryptic species that require a broad suite of methods to distinguish, and extrinsic factors, such as uncertainties in the allocation of scientific names to species. these uncertainties can be due to a wide variety of factors, including old and poorly preserved type specimens (which contain only heavily degraded dna or have lost important diagnostic characters), inappropriately chosen type specimens (e.g. juveniles ... | 2020 | 33154397 |
