jrich: Jack-Knife Support for Evolutionary Distinctiveness Indices I and W. These functions calculate the taxonomic measures presented in Miranda-Esquivel (2016). The package introduces Jack-knife resampling in evolutionary distinctiveness prioritization analysis, as a way to evaluate the support of the...

Hotspots of risk for different taxa rarely overlapped, and overall, 50% of the terrestrial surface was identified as a hotspot of risk from at least one threat for one taxonomic group (Fig.4h). High-priority areas for threat mitigation were identified as the Himalayas, Southeast Asia, the eas...

Less emphasis has been placed on understanding the many technical challenges of compiling and maintaining such a list. Challenges include details of implementation such as defining what each entry on the list represents, the scope (taxonomic breadth), granularity (only species, all taxonomic ranks, ...
2. I used multiple data sources to compile a list of vascular plants for the greater metropolitan Toronto region. This data not only includes taxonomic information but also global and national status ranks, growth from, native status, threatened status, abundance estimates and year of first ...
The taxonomic status of this plant is unclear. Currently, F. baldschuanica is treated as a synonym of Fallopia aubertii [4,5,6], although until recently these species had been separated as a different taxon [7,8]. The plant is native to Asia, mainly distributed in China, Russia, ...
