Killing them softly failure by fatigue in the wave-swept macroalga Mazzaella
Meeting Abstract S4.4 Monday, Jan. 4 Killing them softly: failure by fatigue in the wave-swept macroalga Mazzaella MACH, K.J.*; STAAF, A.V.; TEPLER, S.K.; BOHNHOFF, J.C.; DENNY, M.W.; Hopkins Marine Station of Stanford University mach@stanford.edu Repeated force application typifies the lives of many plants and seaweeds. Winds repeatedly blow through the branches of trees; waves regularly crash over […]
How do climbing plants climb
Meeting Abstract S4.1 Monday, Jan. 4 How do climbing plants climb? ROWE, N.P.; CNRS, Univ Montpellier, France nrowe@cirad.fr Climbing plants have fascinated biologists since the pioneering works of Charles Darwin and his contemporaries. One of the most noticeable aspects of climbing plant diversity is the range of attachment organs that have evolved to initiate attachment and maintain […]
Functional Morphology and Biomechanics of Fruit Walls and Nut Shells Concept Generators for Innovative Biomechanic Materials
Meeting Abstract S4.7 Monday, Jan. 4 Functional Morphology and Biomechanics of Fruit Walls and Nut Shells: Concept Generators for Innovative Biomechanic Materials SEIDEL, R.*; THIELEN, M.; SCHMITT, C.; BÜHRIG-POLACZEK, A.; FLECK, C.; SPECK, T.; Plant Biomechanics Group, Botanical Garden, University of Freiburg, Germany ; Plant Biomechanics Group, Botanical Garden, University of Freiburg, Germany; Plant Biomechanics Group, Botanical […]
Floral Trebuchets, Airguns and Elaters Effect Rapid Spore Dispersal in Low Growing Plants
Meeting Abstract S4.8 Monday, Jan. 4 Floral Trebuchets, Airguns and Elaters Effect Rapid Spore Dispersal in Low Growing Plants EDWARDS, J.*; WHITAKER, D.L.; Williams College; Pomona College joan.edwards@williams.edu Wind-dispersed spores of ground dwelling plants are small with low terminal velocities so they can be held aloft and carried long distances. The height of spore release determines the […]
Elucidating the mechanical principles of stem movements in heliotropism
Meeting Abstract S4.3 Monday, Jan. 4 Elucidating the mechanical principles of stem movements in heliotropism RUEGGEBERG, M.**; BURGERT, I.; FRATZL, P.; Max-Planck-Institute of Colloids and Interfaces, Potsdam, Germany; Max-Planck-Institute of Colloids and Interfaces, Potsdam, Germany; Max-Planck-Institute of Colloids and Interfaces, Potsdam, Germany markus.rueggeberg@mpikg.mpg.de Heliotropism is the movement of plant organs such as leaves or flowers in order […]
Bending corallines biomechanical adaptations of segmented calcified seaweeds
Meeting Abstract S4.6 Monday, Jan. 4 Bending corallines: biomechanical adaptations of segmented calcified seaweeds MARTONE, Patrick T.; University of British Columbia pmartone@interchange.ubc.ca Flexibility is a critical characteristic of plants growing in unsteady flow. For example, leaves flutter in the wind and seaweeds ‘go with the flow’ to reduce drag. Given this paradigm of flexibility, I explore calcified […]
Variation, Selection, and Ecological Constraints in the Sensory-Motor Systems of Fishes
Meeting Abstract S4.3 Wednesday, Jan. 5 Variation, Selection, and Ecological Constraints in the Sensory-Motor Systems of Fishes TRICAS, T.C.; Hawaii Inst of Marine Biology and Univ. Hawaii at Manoa, Honolulu tricas@hawaii.edu The field of modern ecology attempts to define processes and interactions responsible for the distribution and abundance of organisms in their environment. These spatial distributions are […]
The neuroecology of competitor recognition
Meeting Abstract S4.9 Wednesday, Jan. 5 The neuroecology of competitor recognition GRETHER, Greg; Univ. of California, Los Angeles ggrether@ucla.edu Territorial animals must decide whether to respond aggressively to intruders. Some intruders represent a competitive threat while others represent no threat or possible mating opportunities. Failing to evict resource competitors is costly but so is evicting potential mates […]
The Neuroecology of Chemical Defenses
Meeting Abstract S4.4 Wednesday, Jan. 5 The Neuroecology of Chemical Defenses DERBY, Charles; Georgia State University cderby@gsu.edu Neuroecological approaches to the study of chemical defenses include identifying natural products released by an individual, describing the cellular and molecular mechanisms of action of these chemicals including effects on sensory neural pathways of recipient individuals, and understanding the consequences […]
