Acclimation in the Eastern red spotted newt (Notophthalmus viridescens viridescens)
Meeting Abstract 23.2 Friday, Jan. 4 Acclimation in the Eastern red spotted newt (Notophthalmus viridescens viridescens) BERNER, N.J.; Sewanee:University of the South, Sewanee, TN nberner@sewanee.edu Eastern red spotted newts are ectotherms, aquatic as adults, and active year-round, breeding even during winter under ice. Field-captured newts seasonally acclimatize the activity of some muscle metabolic enzymes, as well as […]
comparison of attachment performance in the hairy and smooth adhesive pads of insects
Meeting Abstract 23.2 Monday, Jan. 5 comparison of attachment performance in the hairy and smooth adhesive pads of insects BULLOCK, J.M.R.*; FEDERLE, W.; University of Cambridge; University of Cambridge jmrb3@cam.ac.uk Despite a strong interest in biomimetic adhesives, the biomechanics of natural adhesive systems are still poorly characterised. Many insects can cling to surfaces via thin films of […]

Meeting Abstract 23.4 Monday, Jan. 5 THE ADHESIVE DISC AND ITS FUNCTIONAL CAPACITY IN NORTERN CLINGFISH Gobiesox maeandricus: Gobiesocidae) AND TIDEPOOL SNAILFISH (Liparis florae: Liparidae): SCALING OF MORPHOLOGY AND SUCTION FORCE MAIE, T*; SUMMERS, AP; Clemson Univ.; Univ. of California, Irvine tmaie@clemson.edu In the intertidal environment, Northern clingfish, Gobiesox maeandricus, and tidepool snailfish, Liparis florae, withstand waves […]
Smart foot secretion – insects dont slip
Meeting Abstract 23.5 Monday, Jan. 5 Smart foot secretion – insects dont slip! DIRKS, JH*; CLEMENTE, CJ; FEDERLE, W; University of Cambridge; University of Cambridge; University of Cambridge jhd32@cam.ac.uk Many insects are able to cling to surfaces using adhesive organs on their feet. Adhesion is mediated by thin films of fluid secretion, which help to compensate surface […]
Attachment forces of single adhesive setae from tarantula feet
Meeting Abstract 23.1 Monday, Jan. 5 Attachment forces of single adhesive setae from tarantula feet PEATTIE, A M*; FEDERLE, W; Univ. of Cambridge; Univ. of Cambridge ap557@cam.ac.uk Spiders and geckos have convergently evolved dry fibrillar adhesives on their feet that allow them to climb smooth vertical surfaces. These two types of adhesives are materially and morphologically distinct. […]
A comparative analysis of claw and toe morphology and clinging performance in mainland and island Anolis

The ecology of life-history trade-offs whole-island manipulations of predation regime in a wild lizard
Meeting Abstract 23.4 Monday, Jan. 4 The ecology of life-history trade-offs: whole-island manipulations of predation regime in a wild lizard COX, Robert M.*; CALSBEEK, Ryan; Dartmouth College robert.m.cox@dartmouth.edu A central tenet of life-history theory is that investment in reproduction compromises survival. Here, we use experimental manipulations of reproductive investment to show that reproduction severely compromises survival in […]
Size matters seasonal plasticity of development in a diapause-destined moth, Helicoverpa zea
Meeting Abstract 23.1 Monday, Jan. 4 Size matters: seasonal plasticity of development in a diapause-destined moth, Helicoverpa zea. CLEMMENSEN, S F*; HAHN, D A; University of Florida; University of Florida sclemmensen@ufl.edu Seasonality presents a problem for organisms because inhospitable conditions like cold temperatures can adversely affect survival, development, and reproduction. Many species mitigate this environmental stress by […]
Sex Change in Two Species of Calyptraeid Gastropods Effects of Nutrition and Perceived Mortality Risk
Meeting Abstract 23.3 Monday, Jan. 4 Sex Change in Two Species of Calyptraeid Gastropods: Effects of Nutrition and Perceived Mortality Risk COLLIN, R*; MéROT, C; Smithsonian Tropical Research Institute; Smithsonian Tropical Research Institute collinr@si.edu Although social control of sex-change has been well documented, little is known about other environmental influences that lead to differences in size at […]
