Meeting Abstract S3-1.5  Friday, Jan. 4  Applications of Thermal Infrared Imaging in Field Biology HRISTOV, N.I.*; BETKE, M.; KUNZ, T.H.; Boston University, Boston; Boston University, Boston; Boston University, Boston hristov@bu.edu Knowledge of where, how, and why organisms behave in their natural environment is an important element of biological investigation. Advanced imaging tools and computer vision analyses have […]

Meeting Abstract S3-1.8  Friday, Jan. 4  Aeromechanics in the Aerosphere: Where Physics meets Flight Biology in Aeroecology SWARTZ, SM*; WILLIS, DJ; BOWLIN, MS; BREUER, KS; Brown Univ; MIT; Univ of Montana; Brown Univ sharon_swartz@brown.edu Analysis of animal flight is typically conducted under conditions vastly different from those experienced by free-ranging organisms. Integrating lab analysis of animal flight […]

Meeting Abstract S3-1.0  Friday, Jan. 4  Aeroecology: Probing and Modeling the Aerosphere KUNZ, Thomas H.*; HRISTOV, Nickolay I.; Boston University; Boston University kunz@bu.edu The aerosphere or planetary boundary layer of the Earth�s atmosphere provides a dynamic fluid medium that facilitates the daily and seasonal movements of birds, bats, insects. No organisms exclusively occupy the aerosphere, but many […]

Meeting Abstract S3-1.2  Wednesday, Jan. 4  What Can “Intermediates” Tell Us About Evolutionary Transitions Between Modes of Invertebrate Development? COLLIN, R; Smithsonian Tropical Research Institute collinr@si.edu Mode of development in marine invertebrates has been largely viewed as a dichotomy between small eggs that develop into free-living planktotrophic larvae and large eggs that bypass the larval stage and […]

Meeting Abstract S3-1.5  Wednesday, Jan. 4  Streblospio benedicti (Spionidae, Annelida) as a model organism for the study of larval evolutionary transitions SCHULT, N.*; MCHUGH, D.; Colgate Univ. dmchugh@colgate.edu Streblospio benedicti represents a rare case of poecilogony and is an ideal model for the integration of approaches to study evolutionary transitions in larval development mode of marine invertebrates. […]

Meeting Abstract S3-1.1  Wednesday, Jan. 4  Poecilogony, polymorphism or polyphenism: a window on larval evolutionary transitions in marine invertebrates KNOTT, K.E.*; MCHUGH, D.; University of Jyväskylä, Finland; Colgate University, USA emily.knott@jyu.fi Poecilogony, intraspecific variation in developmental mode, has been described in some marine invertebrates. Poecilogonous species produce different larval forms (e.g. free-swimming planktotrophic larvae as well as […]

Meeting Abstract S3-1.7  Wednesday, Jan. 4  Poecilogony in the polychaete Polydora cornuta: A potential polyphenism that requires decisions, decisions, decisions. GIBSON, G D; Acadia University glenys.gibson@acadiau.ca Poecilogonous species are wonderful organisms with which to investigate the mechanisms that underlie developmental decisions leading to phenotypic divergence. For example, broods of the spionid Polydora cornuta contain eggs that develop […]

Meeting Abstract S3-1.3  Wednesday, Jan. 4  Origins of poecilogony and shifts in larval type in photosynthetic sea slugs: a phylogenetic perspective VENDETTI, J. E. *; KRUG, P. J. ; California State Univ., Los Angeles jannvendetti@yahoo.com The Sacoglossa are a clade of specialized algae-eating sea slugs, some of which retain functional chloroplasts in their own tissues for weeks […]

Meeting Abstract S3-1.6  Wednesday, Jan. 4  Looking for poecilogony in the Streblospio benedicti genome ROCKMAN, Matthew; New York University mrockman@nyu.edu Larval traits couple development and ecology. Alleles at loci that influence larval morphology have pleiotropic effects on feeding and predation and on their own gene flow. Though such loci must underlie evolutionary transitions in larval form, the […]

Meeting Abstract S3-1.4  Wednesday, Jan. 4  Ecological triggers and evolutionary consequences of alternative larval types in sea slugs KRUG, P.J.*; GORDON, D.; California State University, Los Angeles pkrug@calstatela.edu Sea slugs in clade Sacoglossa evolve lecithotrophy at a high rate, and five species express larval dimorphisms. Poecilogony may facilitate shifts in larval type and could promote speciation, but […]
