Accounting for clonality in plant demography – a story of an unintended article (23.11.2017)
The story of this article started already some three years ago at the BES symposium Demography beyond populations organised by Rob Salguero-Gómez and colleagues. Two of us were sitting in the auditorium and listening to talks, when almost simultaneously we had the same idea. “Do clonal species differ in their demographic characteristics? They definitely should, […]

We got the grant! (14.8.2017)
On August 5, the COMPADRE/COMADRE team was awarded an NSF grant to further develop our matrix databases. The funded project, “An Open-Access Global Repository of Plant and Animal Demographic Data”, will be led by Judy Che-Castaldo at Lincoln Park Zoo in Chicago, IL. This funding comes from the Advances in Biological Informatics program and will […]

Our upcoming workshop in Portland, OR (2.8.2017)
Over the last few years we have run numerous workshops on using the COMPADRE Plant Matrix Database and COMADRE Animal Matrix Database, and on matrix population models (MPMs) more generally. Where better to run our next workshop than the upcoming Ecological Society of America (ESA) meeting in Portland, Oregon? This yearly conference brings together academics, […]

Illuminating the world’s demographic dark corners (28.4.2017)
Perhaps by pure coincidence, I was the first user to have downloaded COMPADRE when it first went live, back in 2014. At that time, Rob Salguero-Gómez and I were at the same airBnB, and ready to attend the EvoDemoS meeting at Stanford. At that time and place, we were less than 60 km from the nearest […]

New version of the COMPADRE & COMADRE portal is coming up (20.3.2017)
Just like winter, a new version of COMPADRE & COMADRE is coming too. This work has been going on for a couple of years now, but we are starting to make some tangible progress and we are excited to share where the project stands at the moment. We assume that you are familiar with the […]

A signature of life history in the stochastic dynamics of structured populations (4.3.2017)
Different species have different average life histories. Such a variation is apparent from key species characteristics like longevity, age of maturity, or the number of offspring produced per clutch. Matrix population models such as those in the COMADRE Animal Matrix Database allow us to calculate and explore the diversity of such characteristics across species, and understand how […]

Using demographic data to help recover endangered species (18.2.2017)
One of the biggest hurdles in conserving endangered species is that most of the time, we know very little about them. Often managers would not know how many individuals currently exist for a given species, let alone more detailed biological information such as how long individuals live, how frequently they reproduce, or how well the […]

Demographic extrapolations: how far can/should we go? (21.11.2016)
Just because you can (extrapolate models using the available demographic data in COMPADRE and COMADRE, and other sources) doesn’t mean you should. Shaun Coutts and colleagues have published a work in Ecology Letters asking how far can one extrapolate demographic outputs within and across species based on demographic knowledge, geographic and phylogenetic distance. The academic […]

The power of comparative demography: booms and busts (21.8.2016)
Jenni McDonald’s work on transient dynamics using COMPADRE was recently recognized with the Postdoctoral Excellence Award of the Plant Population Ecology of the Ecological Society of America. Congrats Jenni! Here we leave you with a short summary of her work.   The natural world is not static and populations don’t exist in a vacuum. Environmental […]

New COMPADRE & COMADRE versions are out! (11.8.2016)
Yesterday, coinciding with the symposium “Landscape demography: Population dynamics across spatial scales” at the 2016 Ecological Society of America annual meeting, where we gave the talk “Global plant and animal demography: tearing the curtain and filling up the gap“, we released the new two versions of the sister databases: COMPADRE version 4.0.0 and COMADRE version […]
