The sensitivity of food web topology to temporal data aggregation

Abstract: There is a host of network measures provided by ecological network analysis in order to better understand food webs. A key question is which network indices to use in studying a particular problem, especially because the biological meaning of many indices is poorly understood. We argue that one aspect to consider when making this decision is the sensitivity of network measures to temporal data aggregation. Aggregating food web data in time is not a matter of choice: to some extent, every food web is temporally aggregated.
