WORTHAM, J.L.; Univeristy of Tampa, Florida: Habitat selection and grooming behaviors of male and female mantis shrimp Marine crustaceans have complex social behaviors, and several studies have documented that these behaviors are influenced by habitat type and territory ownership. Mantis shrimp, also called stomatopods, are predatory, benthic crustaceans that live in defendable burrows and exhibit […]

In 2003, the forth species of amphioxus was […]

WOTTON, KR*; MAZET, F; SHIMELD, SM; University of Oxford; University of Reading; University of Oxford: Fox gene duplication in vertebrate evolution The genome of higher vertebrates has undergone many duplication events. Often these duplication events appear to be associated with phenotypic changes. For example, during the evolution of vertebrates, mesodermal patterning has been substantially elaborated […]

BAKER, Shirley M.*; FAJANS, Jon S.; University of Florida; University of Florida: Feeding rates in the invasive green mussel, Perna viridis; Potential for ecosystem change. Suspension feeding bivalve molluscs have the capacity to regulate ecosystem function to a large degree. Bivalves as biological invaders have received considerable attention, owing to the success of species like […]

TANAKA, K*; TRUMAN, JW; Univ. of Washington, Seattle; Univ. of Washington, Seattle: Expression of patterning genes in the larval and the adult legs of Manduca sexta The tobacco hornworm Manduca sexta, like most holometabolous insects, makes two versions of thoracic legs. The simple thoracic legs of the larva are formed during embryogenesis. All the epidermal […]

FAIRCLOTH, LM*; SHAFER, TH; University of North Carolina Wilmington; University of North Carolina Wilmington: Expression of Various Genes for Cuticle Proteins in the Blue Crab, Callinectes sapidus The blue crab is an ideal organism in which to study biomineralization. Throughout its life it goes through many molt cycles in which the exoskeleton is shed and […]

MASLAKOVA, S. A.*; MATZ, M. V.; University of Washington, Friday Harbor Labs; University of Florida, Whitney Laboratory: Evolution of Larval Development in Nemerteans (Phylum Nemertea) The origin of morphological diversity is the central question of evolutionary developmental biology. Nemerteans, a poorly understood lophotrochozoan phylum, present a particularly interesting study group in this respect, because they […]

OLLIKAINEN, N.*; CHANDSAWANGBHUWANA, C.; Univ. of California, San Diego: Evolution of Ecdysone and Thyroid Hormone Receptors Ecdysone and thyroid hormone are two ligands that have important roles in regulating metamorphosis in animals. Ecdysone is a steroid, that regulates molting in insects. Thyroid hormone is a non-steroidal ligand, that regulates differentiation and development in fish and […]
