COMPADRE & COMADRE databases

Goal: 1) Maintain an open-access database of matrix population models from both animals and plants to facilitate its usage for scientific and teaching purposes.
2) Promote access and application of demographic data

We've released new versions of COMPADRE (6.20.11.1) and COMADRE (4.20.11.1)! In addition, we're updating the version release schedule. Going forward, database releases will be quarterly and on the 15th of the first month of the quarter. The 2021 release schedule follows.
January 15, 2021
April 15, 2021
July 15, 2021
October 15, 2021
In the event of major database updates, we may also release versions outside of the primary schedule.
We've also had a major addition to the COMADRE database including more than 1,100 human (Homo sapiens sapiens) matrices. This was made possible by Tom Ezard and Alex Nicol-Harper (University of Southampton). Check out our blog (https://compadre-db.org/AboutUs/Blog) for a recent post from Alex about this new addition!

Our Summer issue of the Newsletter is out!
Take a look at the attached PDF to find out what we have been up to this summer, plus we have a new online querying of the database and we share information on the new up-coming database project: Padrino.
Enjoy!

We are very excited to announce that a new version of our databases is out!
There are now 760 species in COMPADRE (plants) and 446 species in COMADRE (animals).
Check out the attached flyer for more information and visit www.compadre-db.org to download the new R objects!

COM(P)ADRE committee members are spread out around the world and are involved in different COM(P)ADRE projects. One way for all of us to communicate our new projects, events and new updates of the databases is through our newsletter. We have now decided to make it available to anyone interested in the databases. Take a look at the attached PDF; we hope you enjoy!

There are multiple statistics and baseline demographic metrics that can be obtained from matrix population models – population growth rate, life history traits, projected population structure, to name a few – that researchers can use to address ecological and evolutionary questions about populations. Our Core Committee member Iain Stott has developed a web application that allows users to calculate these statistics and more using the R shiny platform. The app can be used with matrices from COM(P)ADRE or with your own data!
It is a great way to visualize and learn about population dynamics, and a useful tool for teaching population biology! We encourage you to take a look:
Read more about this webapp from the attached excerpt written by Iain.

An example of the kind of questions we can answer with our repository of demographic data is the one recently published by core committee member Judy P. Che-Castaldo and colleagues.
They used COMPADRE plant matrix database to explore the idea of borrowing demographic information from a phylogenetically related or biologically similar species when data are not available for a focal species. The authors found that vital rates such as survival and growth between related species or even among populations of the same species could be very different, and therefore borrowing data is not recommended.

Welcome to our COMPADRE & COMADRE database project!
The databases are a repository containing demographic information --in the form of population matrices --for hundreds of animals and plants species all over the world. It was initiated in 1989 by Jonathan Silvertown and Miguel Franco and at first it was created as a repository for plant demographic data (COMPADRE). Now, led by Roberto Salguero-Gómez and Owen Jones , we also include the COMADRE database for animal data! We are currently composed of three teams: Core committee, a science committee and a digitization team.
Why are we maintaining this repository? Because there is huge potential to address global ecological and evolutionary questions using these databases -- Check the "references" tab within the project page to access the numerous published papers using data from COMPADRE & COMADRE. Our main goal is to keep these databases open access and facilitate their usage for scientific and teaching purposes.
We are continuously working on improving the databases --from fixing errors to giving workshops on its usage at different conferences; follow our project to keep informed on the latest news.
