Contractile Properties and Myosin Expression in Swimming and Feeding Muscles of Centrarchid Fishes
Meeting Abstract 6.10 Wednesday, Jan. 4 Contractile Properties and Myosin Expression in Swimming and Feeding Muscles of Centrarchid Fishes COUGHLIN, D. J.*; MISTRY, H.; CAMPION, L. A.; CHOI, S.; Widener Univ.; Widener Univ.; Widener Univ.; Widener Univ. djcoughlin@widener.edu In centrarchid fishes, such as bluegill and largemouth bass, the contractile properties of feeding and swimming muscles show different […]
When settlement doesn’t settle it the pitfalls of still-water larval assays
Meeting Abstract 5.2 Wednesday, Jan. 4 When settlement doesn’t settle it: the pitfalls of still-water larval assays LOH, T.-L.*; PAWLIK, J.R.; University of North Carolina Wilmington; University of North Carolina Wilmington tl7275@uncw.edu For many marine sessile invertebrates, the swimming larva is the sole motile phase in the organism’s life cycle. Much research has been focused on the […]
The effects of temperature on the developmental energetics of a sea urchin with indirect larval development
Meeting Abstract 5.5 Wednesday, Jan. 4 The effects of temperature on the developmental energetics of a sea urchin with indirect larval development WHITEHILL, E.A.G.*; MORAN, A.L.; Clemson University; Clemson University whitehi@clemson.edu The early life history stages of marine invertebrates are strongly affected by temperature, and these effects can carry over into juvenile and adult stages. Rearing temperature […]
Sensory mechanisms utilized by coral planulae to detect settlement cues
Meeting Abstract 5.3 Wednesday, Jan. 4 Sensory mechanisms utilized by coral planulae to detect settlement cues TRAN, C*; HADFIELD , MG; University of Hawaii at Manoa; University of Hawaii at Manoa cawa@hawaii.edu Coral planulae require environmental cues on substrata to settle and metamorphose into polyps. Sensory cells used to detect settlement cues are located in the apical […]
Response of Crepidula larvae to temperature as a function of geography and developmental mode existence of local adaptation
Meeting Abstract 5.4 Wednesday, Jan. 4 Response of Crepidula larvae to temperature as a function of geography and developmental mode: existence of local adaptation CAHILL, A.E.; Stony Brook University acahill@life.bio.sunysb.edu Distributional changes are expected to become more common in the face of global climate change as species that cannot adapt to changing temperatures expand, contract, or shift […]
Benthic baby snatchers predation on marine invertebrate embryos inside gelatinous egg masses
Meeting Abstract 5.1 Wednesday, Jan. 4 Benthic baby snatchers: predation on marine invertebrate embryos inside gelatinous egg masses VON DASSOW, Y.J.; Duke University, NC yasmin.vondassow@duke.edu A common reproductive strategy for marine invertebrates involves the packaging of embryos into benthically-deposited egg structures. Some of these structures take the form of gelatinous masses with embryos embedded inside. The energetic […]
A caterpillar grows up thermal consequences of growing larger on a leaf
Meeting Abstract 5.6 Wednesday, Jan. 4 A caterpillar grows up: thermal consequences of growing larger on a leaf WOODS, HA; Univ. of Montana art.woods@mso.umt.edu Leaf-associated insects live partially or entirely within leaf boundary layers. Because leaves transpire, boundary layers can be cooler and more humid than ambient air. I examined the thermal consequences of living within versus […]
Ontogenetic evidence and performance consequences of re-acquisition of planktotrophy in the gastropod family Calyptraeidae
Meeting Abstract 4.4 Wednesday, Jan. 4 Ontogenetic evidence and performance consequences of re-acquisition of planktotrophy in the gastropod family Calyptraeidae MCDONALD, K.A.; Smithsonian Tropical Research Institute characterforming@gmail.com Phylogenetic hypotheses suggest that different lineages of calyptraeid gastropods have regained free-swimming, feeding larvae following loss of the ancestral type of planktotrophic development. This runs counter to expectations based in […]
Maternal provisioning in echinoids the role of egg constituents during pre-feeding larval development
Meeting Abstract 4.5 Wednesday, Jan. 4 Maternal provisioning in echinoids: the role of egg constituents during pre-feeding larval development MCALISTER, J/S*; MORAN, A/L; Clemson University; Clemson University jmcalis@clemson.edu Marine invertebrates with feeding larvae utilize maternally-provisioned material (protein, lipid, and carbohydrate) in the egg for morphogenesis and metabolism during early pre-feeding larval development. All eggs are not provisioned […]
