Food web summary statistics (* denotes chain length statistics incorporating cannibalistic links).

[L and A are the length and angle, respectively, of a link between consumer and resource in three node food chains; upper refers to the link between a consumer and intermediate taxon (resource); lower refers to the link between an intermediate taxon (consumer) and a resource; Abetween refers to the angle between the upper and lower components]. Tritrophic measures are provided for 2011 only because these require additional estimates of body mass and abundance which were not available for all taxa in 2006 and 2008.
