### The Mathematics of Biodiversity

#### Posted by Tom Leinster

Interested in biological diversity? Want to know more about how diversity can be quantified? Maybe diversity comes up in your work. Maybe you’ve heard rumours that there’s serious mathematics involved, and you want to know more. Or maybe you’re just curious.

If so, come to a meeting in Barcelona! It’s running 2-6 July, and there are grants to cover attendance expenses. (If you want one, please apply as soon as possible.) We also have free slots for contributed talks.

We’ve assembled what is already a head-spinningly varied group of people, from livestock breeding experts to ostensibly pure mathematicians to evolutionary ecologists. Two or three of your Café hosts will be there. Details follow.

What is diversity? How do we measure it? This event brings together life scientists and mathematicians to advance our understanding of diversity and its measurement. We welcome everyone with an interest in measuring diversity, from microbial biologists to pure mathematicians to conservation ecologists.

Grants for attendance expenses are available. The official deadline to apply is 30 April. If you want to apply but think you will miss the deadline (or have already missed it), all is not lost: let us know at the addresses below.

We are also taking offers of contributed talks. If you would like to give one, please contact us as soon as possible.

Our current list of speakers is:

- Benjamin Allen (Program for Evolutionary Dynamics, Harvard)
- John Baez (Mathematics, Riverside)
- Michael Bonsall (Zoology, Oxford)
- Anne Chao (Statistics, National Tsing Hua Univ., Taiwan)

## Re: The Mathematics of Biodiversity

Your ‘Measuring diversity’ paper is referred to by Pavlovic here in a paper which prefers ‘proxets’, categories enriched over the multiplicative monoid $[0, 1]$, to the equivalent generalized metric spaces.
