Article Synopsis
- The study reevaluates the fern genus Pecluma, revealing it may not be monophyletic due to the inclusion of several Polypodium species.
- Using a genome-skimming method and fossil analysis, researchers establish Pecluma's phylogenetic position and suggest its biogeographic history originated in Eocene South America with later expansions to Central America and the West Indies.
- The findings support the establishment of three new species combinations under Pecluma, indicating a stable generic composition in the Greater Antilles since the Miocene.
This study summarizes results of a DNA barcoding campaign on German Diptera, involving analysis of 45,040 specimens. The resultant DNA barcode library includes records for 2,453 named species comprising a total of 5,200 barcode index numbers (BINs), including 2,700 COI haplotype clusters without species-level assignment, so called "dark taxa." Overall, 88 out of 117 families (75%) recorded from Germany were covered, representing more than 50% of the 9,544 known species of German Diptera.

View Article and Find Full Text PDFThe monospecific fern genus Cystodium (Cystodiaceae; Polypodiales) occurs exclusively in the tropical forests of the Malay Archipelago, the Admiralty Islands, the Louisiade Archipelago, and the Solomon Islands. Divergence time estimates suggest that the genus originated in the Mesozoic; however, fossil evidence to validate this suggestion has been lacking. Amber from Myanmar (Burmese amber) is an important source of new information on the diversity of vascular cryptogams in the Cretaceous.
