Genomic Evidence Suggests Further Changes Of Butterfly Names, Jing Zhang, Qian Cong, Jinhui Shen, Pal A. Opler, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

Further genomic sequencing of butterflies by our research group expanding the coverage of species and specimens from different localities, coupled with genome-scale phylogenetic analysis and complemented by phenotypic considerations, suggests a number of changes to the names of butterflies, mostly those recorded from the United States and Canada. Here, we present evidence to support these changes. The changes are intended to make butterfly classification more internally consistent at the genus, subgenus and species levels. That is, considering all available evidence, we attempt to assign similar taxonomic ranks to the clades of comparable genetic differentiation, which on average is correlated with …

USDA Wildlife Services: Staff Publications

Invasive mammals, particularly black rats (Rattus rattus), house mice (Mus musculus), and mongoose (Herpestes auropunctatus) are established on many tropical islands and threaten natural resources such as native birds, sea turtles, lizards, invertebrates, and plants. St. Croix (U.S. Virgin Islands, Caribbean) has a diversity of natural resources being protected from invasive mammals by U.S. conservation agencies. Sandy Point National Wildlife Refuge and Buck Island Reef National Monument receive among the highest density of nesting sea turtles in the region, including annual nesting populations of 50e250 leatherbacks (Dermochelys coriacea), 25e80 hawksbills (Eretmochelys imbricata), and 100e250 green turtles (Chelonia mydas). Buck Island …
