Nanotechnology's many disciplines. With their large, self-organizing systems, biologists need to collaborate with physical scientists who are developing the techniques for observation and nanofabrication
Efficiency of detecting color-banded herring gulls (Larus argentatus) and lesser black-backed gulls (Larus fuscus) at the breeding colony: Practical implications for the determination of adult survival rates
Calfifornia condor occurrence data, downloaded from USGS BISON. The USGS Biodiversity Information Serving Our Nation (BISON) project is an online mapping information system consisting of a large collection of species occurrence datasets (e.g., plants and animals) found in the United States, with relevant geospatial layers. Species occurrences are records of organisms at a particular time and location that are often collected as part of biological field studies and taxonomic collections. These data serve as a foundation for biodiversity and conservation research. BISON supports several data interchange formats to enable developers to write custom applications (http://bison.usgs.ornl.gov/services.html). The BISON...
THIS IS A HISTORICAL RECORD. As of December 17, 2021, the BISON application will no longer be available online and has been replaced by https://www.gbif.us. The BISON APIs are still available at https://bison.usgs.gov/#api and the Integrated Publishing Toolkit is still available at https://bison.usgs.gov/ipt. The USGS Biodiversity Information Serving Our Nation (BISON) project is an online all-species mapping information system consisting of a large collection of species occurrence datasets (e.g., plants and animals) found in the United States, U.S. Territories, U.S. marine Exclusive Economic Zones (EEZ), and Canada, with relevant geospatial layers. Species occurrences are records of organisms at a particular...
