AJEMIAN, Matthew J.; SANFORD, Christopher P;; Hofstra University; Hofstra University: Kinematics of prey capture in the chain catshark Scyliorhinus retifer Modulation of prey capture has been observed in several aquatic vertebrates and may represent a fitness advantage when resources are scarce and varied. However, the presence of modulation in feeding among the elasmobranchs (sharks, skates, […]

PANAITOF, S.C.; SCOTT, M.P.; Univ. of New Hampshire, Durham; Univ. of New Hampshire, Durham: Juvenile hormone and parental responsiveness in single male burying beetles, Nicrophorus orbicollis Burying beetles, Nicrophorus orbicollis, have facultative biparental care. They bury and prepare small vertebrate carcasses that provide food for their young; both remain to feed and guard the young. […]
