and used the following environmental variables: Bioclim 1–19, elevation, net primary productivity (mean monthly MODIS Normalized Difference Vegetation Index; NDVI), and percentage of woody plants (datasets downloaded from http://www.paleoclim.org/ and https://github.com/rebeccalpowell/grassmapr)...
We created a "base map" of North American raptor δDf that incorporated the regional variation described by our sample. We plotted δDf values from migrant Sharp-shinned Hawks (Accipiter striatus) captured in eastern Nevada directly on this map to demonstrate how it can be used to view the ...
Similarly, American Bird Conservancy has partnered with Mexican NGO Pronatura Noreste to promote sustainable practices in the region. Another Mexican NGO, Especies, Sociedad, y Habitat (Species, Society, and Habitat), has primarily worked with ejidos to conserve habitat through agreements, community ...

The northwestern portion of the state, corresponding to the Red River Valley and the drainage basin to the Hudson Bay was, at the time, part of Rupert's Land, a British North American territory. It remained under control of the Hudson's Bay Company until the Anglo-American Convention of 18...

A map in the Greenland Museum showing the migration of native Inuit from Asia, across the Arctic region, to Greenland. Greenland was first settled by migrating native Inuit tribes who migrated across the North American Arctic region, from Asia, more than 4,500 years ago. An Inuit whale-bon...
We investigate the perceptions and impacts of climate change on 11 Indigenous communities in Northern British Columbia and Southeast Alaska. This coastal r
Alternatively, it is possible that population densities in North America may have been too low to have global implications (Ubelaker1992; Steckle and Rose2005; Liebmann et al.2016) and past changes in atmospheric gas levels were not directly influenced by Indigenous American land use (Bird et al...
