Includes all Neotropical stingless bee (Hymenoptera: Apidae, Meliponini) species, with trait data collected from the literature and unpublished data. Traits include worker body size, colony size, nest description, foraging strategy, aggressiveness, flight range, etc. All data entered have been matched to current species names, following the Moure catalog ( http://moure.cria.org.br/index...MORE
Includes published and unpublished records of Neotropical stingless bee (Hymenoptera: Apidae, Meliponini) plant usage determined through both transect studies and pollen analyses. I have matched data to current bee species names following the Moure catalog ( http://moure.cria.org.br/index ), and plant classification following GBIF ( http://data.gbif.org/welcome.htm ).

A large compilation of empirical data on how traits respond to environmental drivers. Dataset Location: The dataset is available both online where selected data for individual populations can be downloaded one at a time and as a Data Paper in Ecological Archives providing access to the entire dataset in one...MORE
This website and database hosts records of fossil pollen, charcoal, and mammal assemblages, as well as plant macrofossils, largely from North America, but also globally, throughout the Pleiocene-Quaternary (and Anthropocene). Also included are chronological controls that allow the use of the records through time from the last 5 million years...MORE
Database including information on distribution, taxonomy, and synonyms for birds. Data location: http://avibase.bsc-eoc.org/ Uses: Of particular interest is the tool for comparing two differt checklists. This provides information to help combine datasets that are based on different taxonomies, and the determine what has changed from one version of the taxonomy...MORE
The USGS Gap Analysis Program (GAP) is delineating species range and predicted distribution maps for more than 2,000 species that occur within the continental US as well as Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands (we will make these maps and datasets available as they are completed). Our...MORE
