Meeting Abstract 1.7 Saturday, Jan. 4 09:30 Testing the thermal melanism hypothesis for lizards VAN DAMME, R*; VROONEN, J; Univ. of Antwerp, Belgium raoul.vandamme@ua.ac.be Melanism is possibly the most common rarity in animal coloration. Starting with Kettlewell’s classic experiments on peppered moths, the phenomenon has received ample attention from evolutionary biologists, but the adaptive significance of melanism […]

Spatial, phylogenetic, and functional ecological perspectives on aquatic insect thermal tolerance
Meeting Abstract 1.2 Saturday, Jan. 4 08:15 Spatial, phylogenetic, and functional ecological perspectives on aquatic insect thermal tolerance BERNARDO, J.; Texas &M University jbernardo@tamu.edu Aquatic insects are key ecological players in freshwater food webs. Accordingly, an understanding of their physiological tolerances to warming waters illuminates the potential responses of aquatic systems, especially streams, to climate change. I […]

A stressful shortness of breath Oxygen consumption patterns associated with molting and thermal challenge in the mayfly Cloeon cognatum
Meeting Abstract 1.3 Saturday, Jan. 4 08:30 A stressful shortness of breath: Oxygen consumption patterns associated with molting and thermal challenge in the mayfly Cloeon cognatum. CAMP, A.*; BUCHWALTER, D.; North Carolina State University; North Carolina State University david_buchwalter@ncsu.edu In insects, one of the more fascinating and improbable aspects of the molt is the fact that not […]
To eject a drop, from wet-dog shaking to urination
Meeting Abstract S10.2-5 Tuesday, Jan. 7 11:34 To eject a drop, from wet-dog shaking to urination HU, David*; DICKERSON, Andrew; YANG, Patricia; Georgia Institute of Technology hu@me.gatech.edu Animals frequently expel fluids from both their surfaces and inside their bodies. Undesired fluids include include rain and dew, accumulated on their surfaces, as well as the products of metabolism […]
The hairy, superhydrophobic surfaces on the water fern Salvinia – underwater air retention and raindrop impacts
Meeting Abstract S10.1-4 Tuesday, Jan. 7 09:03 The hairy, superhydrophobic surfaces on the water fern Salvinia – underwater air retention and raindrop impacts MAYSER, M.J.*; BARTHLOTT, W.; GILET, T.; University of Liege; University of Bonn; University of Liege m.mayser@ulg.ac.be Superhydrophobic surfaces are of high scientific and economic interest because of their remarkable properties. Recently the immense potential […]
Surface tension in human lungs modeling and experiments
Meeting Abstract S10.2-2 Tuesday, Jan. 7 10:16 Surface tension in human lungs: modeling and experiments LEVY, R*; SWANSON, E; DANIELS, K; STRICKLAND, S; Harvey Mudd College; Centre College; NC State University; NC State University levy@hmc.edu Naturally produced surfactant, which lowers surface tension is required for normal human lung function. Premature babies born before surfactant production begins, are […]
Self-burial mechanics of hygroscopically responsive awns
Meeting Abstract S10.3-3 Tuesday, Jan. 7 14:30 Self-burial mechanics of hygroscopically responsive awns JUNG, Wonjong; KIM, Wonjung; KIM, Ho-Young*; Seoul National University; Sogang University; Seoul National University hyk@snu.ac.kr We present the results of a combined experimental and theoretical investigation of the mechanics of self-burial of some plant seeds whose morphologies respond to humidity change of the surroundings. […]
Rain-operated foliar disease transmission
Meeting Abstract S10.1-3 Tuesday, Jan. 7 08:37 Rain-operated foliar disease transmission GILET, T.*; BOUROUIBA, L.; University of Liège, Belgium; Massachusetts Institute of Technology tristan.gilet@ulg.ac.be Plant diseases are a major cause of crop loss worldwide. They are known to be triggered by rainfalls. We here combine high-speed visualizations and physical modelling to elucidate the causal link between rain […]
Insect Flight on a Fluid Interfaces and Chaotic Oscillators
Meeting Abstract S10.2-4 Tuesday, Jan. 7 11:08 Insect Flight on a Fluid Interfaces and Chaotic Oscillators PRAKASH, M*; MUKUNDARAJAN, H; Stanford University; Stanford University manup@stanford.edu Here we present the discovery of a novel mode of interfacial “2D flight” in water lily beetles (Galerucella nymphaeae), that are capable of multiple modes of flapping-wing locomotion along a fluid interface, […]
