According to Tinn & Meidla (2003), the A-3 stage in early Middle Ordovician ctenonotellids (Brezelina paimata) and tetradellids (Ogmoopsis bocki) marks the first appearance of dimorphic admarginal structures (distinction of pre-adult heteromorphs possible for the first time).
More heavily calcified bryozoans, however, do not fare well in lower-pH waters: Schizoporella errata showed skeletal corrosion and less investment in defensive heteromorphs (Lombardi et al., 2011a), and the larger Mediterranean bryozoan Myriapora truncata showed dissolution and lowered Mg in skeletal calcite under elevated pC[O.sub.2] (Lombardi et al., 2011b).
Similarly, when sexually mature damselfly (Enallagma civile) males were exposed only to andromorphic females, they were significantly more likely to initiate mating behaviors with other andromorphs compared to heteromorphs (Miller and Fincke, 1999).
