Evolution 2014: Are island mutualist communities more likely to be nested because they are inherently more unstable?

Posted 21 Jun 2014 / 0

The interactions in ecological communities can be structured in a variety of ways, and recently there has been a push to categorize these networks along the spectrum between modular (smaller clusters of more specialized interactions) and nested (unclustered networks with more generalist species). Theoretically it is understood that the nested communities are more stable, so Read More

Perhaps nestedness is just an artifact of ecological opportunity (and not stability)

Posted 27 Jun 2012 / 0

One of my chief interests is stability: I am curious about what allows for the persistence of genes, individuals, groups, species, and communities. This is a broad question and it may not have single, simple answer, but it is exciting to think that there may be ‘rules of stability’ in nature that might help us Read More

ESA 2009 Day #3 (Tuesday) – Mutualistic Networks Symposium

Posted 05 Aug 2009 / 0

I spent Tuesday morning in a really well-organized symposium entitled “Mutualistic Networks”. Headed up by Jordi Bascompte, the collected talks focused on the network architecture of mutualistic interactions, mostly among plants and their various insect pollinators. I came in with only a very basic understanding of matrix-based interaction networks, but Bascompte’s introduction to the session Read More
