title: Ranges Network collected mammal trait measurements and summary from western North America

description: Over the past two decades, digitization of U.S. vertebrate collections has opened critical temporal, spatial, and taxonomic information from specimens, stimulating new levels of data sharing and significantly advancing biodiversity knowledge. However, still missing are the specimen-level trait data essential for establishing faunal baselines and informing predictions of global change response. We propose the Ranges Digitization Network (Ranges), which will close this gap by mobilizing an estimated >5 million trait measurements from 1.2 million specimens from Western North America (WNA). WNA is a region of high temperate mammal diversity and a natural laboratory for studying speciation, phenotypic diversification, biogeographic principles, and community assembly over deep and shallow timescales. To build capacity for transformative research in these areas, Ranges brings together a digitization network of 19 institutions, expands informatics tools for trait extraction and standardization from specimen records, and immediately (in Year 1) provisions specimen-linked trait data in usable form via existing portals. The specific goals of Ranges will be to: 1) Digitize traits from 1.2 million mammal specimens, append these to digital records, and publish openly in community repositories; 2) digitize, georeference, and mobilize four regionally significant mammal collections, making their data research-ready for the first time; and 3) develop dense, intraspecific-level 3D image resources for >3,500 mammal specimens to facilitate acquisition of complex internal traits that can be linked to complimentary, specimen-level datasets existing in an extended specimen network. 

 

The Ranges Project

Ranges is an NSF-funded project that seeks to digitize traits from over one million mammal specimens from 19 natural history museums, with a focus on western North America.

The project will allow researchers to build better baselines for biodiversity and improve predictions of how mammals respond to changing environments to address major digitization challenges, expand the utility of specimens and use them to create new scientific knowledge.

Ranges Baseline Sources

The Ranges Baseline Trait Collection contains 19 datasets downloaded from the Global Biodiversity Information Facility (GBIF) in January/February of 2024. The institutions represented are all participants in the Ranges Network. The purpose of this dataset is (1) to provide a baseline of the traits digitized by the 19 Ranges institutional participants prior to the start of the Ranges digitization effort, and (2) to update the FuTRES traits index to include occurrenceIDs for each record in the FuTRES traits portal (https://futres-data-interface.netlify.app/).

Taxonomic Representation*:

Percent of Extracted Digital Traits by Mammalian Order - See attached file, Graphic_ Percent of Extracted Digital Traits by Mammalian Order.pdf.

Each layer of the plot depicts cumulative percent of traits available per taxonomic Order. The outer layer shows values for all traits, and the inner two layers show values for just morphological and reproductive traits, respectively. Only data that were mappable to a formerly or currently recognized mammalian order were considered.
