On page 831, zoologists describe how a native mussel of New England has rapidly evolved the ability to shield itself from an invasive crab, indicating that native species aren9t always helpless when an invader arrives on the scene. (Read more.) 

Nutrient and energy acquisition by harlequin ducks foraging for an exotic crab, Carcinus maenas, and a native crab, Hemigrapsus oregonensis

Examining the feeding behavior of captive harlequins and compare energy and nutrient contents of native crab, Hemigrapsus oregonensis to invasive exotic crab, Carcinus maenas found green crabs provide a viable food option to harlequin ducks, if yellow shore crabs are not available.

Gilbert Gottlieb: intermediator between psychology and evolutionary biology.

Gilbert Gottlieb proposed that altered developmental conditions gave rise to new behavioral phenotypes (behavioral neophenotypes) that could provide the basis for initiating speciation that were based on actual evolutionary processes including recent developments in the field of evo-devo.
