bioRxiv (pronounced "bio-archive") is a free online archive and distribution service for unpublished preprints in the life sciences. It is operated by Cold Spring Harbor Laboratory, a not-for-profit research and educational institution. By posting preprints on bioRxiv, authors are able to make their findings immediately available to the scientific community and receive feedback on draft manuscripts before they are submitted to journals.

A dataset of 3,250,404 measurements, collated from 26,114 sampling locations in 94 countries and representing 47,044 species. The data were collated from 480 existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world. The database was assembled as part of the PREDICTS project - Projecting Responses of Ecological Diversity In Changing Terrestrial Systems; www.predicts.org.uk.

The taxonomic identifications provided in the original data sets are those determined at the time of the original research, and so will not reflect subsequent taxonomic changes.

Mass spectrometry (MS) is an essential part of the cell biologist’s proteomics toolkit, allowing analyses at molecular and system-wide scales. However, proteomics still lag behind genomics in popularity and ease of use. We discuss key differences between MS-based -omics and other booming -omics technologies and highlight what we view as the future of MS and its role in our increasingly deep understanding of cell biology.

The Molecular Ecologist is a website for people interested in the applications of population genetic data in studies of evolution, ecology, and diversity. Our contributors are mostly scientists working in the fields of ecology, evolutionary biology, and behavior, and we often write about the technical details of research in our fields — but we hope that much of what we cover here is also interesting to members of the general public.

The National Association of Biology Teachers (NABT) is "the leader in life science education." To date, more than 9,000 educators have joined NABT to share experiences and expertise with colleagues from around the globe; keep up with trends and developments in the field; and grow professionally. The National Association of Biology Teachers empowers educators to provide the best possible biology and life science education for all students.
