Wood-eating clams use their poop to dominate their habitat: Study
). Despite the fact that a given piece of wood is a finite resource that xylophagaids must consume to survive, biotic interactions among borers within a wood fall have been largely ignored. If one species, or a group of related species, can dominate a wood fall by means such as higher fecundity, increased larval availability, or mixotrophy, the contrast between long-lived, robust, and short-lived, heavily bored wood falls might be simply explained.
Here we use a meta-analysis including multiple xylophagaid-bored deployments from around the world to compare the taxonomic composition of borers in wood that remained largely intact to those in wood that was crushable by hand on recovery. We assign the xylophagaids removed from wood of contrasting condition to their respective clades defined by anterior adductor cover and siphon morphology and molecular characters .
Deployments considered to be heavily bored were those the authors reported were crushable by hand at recovery. Deployments considered to be largely intact were those the authors noted to be solid or intact or to require use of a hammer and chisel to sample the xylophagaids. We quote the published description of the recovered wood in Table
