Meeting Abstract 98.4  Sunday, Jan. 6  Herbivorous prickleback fishes (family Stichaediae) express multiple amylase isoforms FOTI, DM*; GERMAN, DP; Univ. of California, Irvine; Univ. of California, Irvine dfoti@uci.edu Many herbivorous vertebrates are reliant upon soluble components of their food (e.g., starch) to meet their energetic needs. Thus, herbivorous vertebrates have elevated activities of the starch-degrading enzyme amylase […]

Meeting Abstract 98.3  Sunday, Jan. 6  Digestive enzyme activities elucidate the digestive strategies of prickleback fishes (family Stichaeidae) with different diets GERMAN, DP; Univ. of California, Irvine dgerman@uci.edu The patterns of digestive enzyme activities along the digestive tract of an animal can reveal the strategy that an animal takes to acquire resources from their food. In this […]

Meeting Abstract 97.4  Sunday, Jan. 6  Rapid Burrowing by the Mantis Shrimp Squilla empusa VETTER, K. M.*; BUMP, P.; Denison University; Univ. of Hawaii, Manoa ksmvetter@gmail.com Mantis shrimp rely on their burrows for shelter, protection from predators, reproduction efforts, and food manipulation. While some species incur great costs during burrow construction and consequently maintain each burrow for […]
