How can we use molecular tools to better understand community dynamics? This is but one of the questions that the recent special issue in Molecular Ecology delves into. This issue focuses on ecological networks where species are the ‘nodes’ and edges represent interactions between species. What I particularly like about this collection of papers is the breadth of taxa from aquatic to terrestrial as well as the breadth of interactions captured from predator-prey to host-symbiont. Most of these communities are hard to observe in nature (i.e. the organisms are small or nocturnal) so thus molecular tools are really the only option.
Lots to learn from this interesting set of papers!
