BioTIME is a database of biodiversity time series. It is freely accessible for research, education and conservation, with appropriate permissions by data owners. However, many parts of the world, particularly those rich in biodiversity, are underrepresented in BioTIME. There are also many taxa with uneven temporal and spatial coverage. We therefore invite you to contribute your biodiversity time series data to BioTIME, to help fill these data gaps and increase understanding of how biodiversity has changed worldwide.

We strongly believe in giving credit to data collectors, as without the efforts of people collecting data it is impossible for synthesis work to take place. We also believe that science benefits from people sharing data. The BioTIME database is publicly available, and supported by an open-access data paper in which all data contributors have been invited to be co-authors. These contributions will establish BioTIME as the standard database for biodiversity time series analysis. By participating, you can ensure that your data remains available into the future and increase the impact of your work with little additional effort on your part.

Our database is built to clearly recognize and give credit to the original data collectors and data owners (that's you!). Our current data use policy is outlined below, but please get in touch with us if you have data to contribute but are uncomfortable with the current terms of this policy. We will do our best to respect data contributor wishes. If you have data to contribute, please use this template to format your data and metadata, and email them to We may contact you for additional details on your data or methods if they are not sufficiently described in the original dataset or publication.

BioTIME is an open access resource, free to anyone, anywhere in the world to use for education, research or conservation. However, the future of the BioTIME database, and its continued availability as a resource for ecologists around the world, depends on our ability to raise funds to secure it over the coming years. If you will be using BioTIME data in a funded research project, please contribute to our running costs. Or, if you are writing a grant proposal for work that will draw on the BioTIME database, please include a contribution to these running costs in your budget. To contribute, or for advice on wording to be included in a grant application, please contact us here. Your support is greatly appreciated and will be acknowledged on the BioTIME website.
