Trade-offs of power amplification on compliant substrates
Meeting Abstract S3-4 Friday, Jan. 4 09:30 – 10:00 Trade-offs of power amplification on compliant substrates REYNAGA, CM*; AZIZI, E; Duke University; University of California, Irvine crystal.reynaga@duke.edu http://crystalreynaga.weebly.com From frogs to fleas, many biological systems utilize power amplifying mechanisms to achieve fast accelerations. Power amplification can have varied performance outputs using the same set of components. To […]
The two Borelli laws for jumping animals
Meeting Abstract S3-10 Friday, Jan. 4 14:30 – 15:00 The two Borelli laws for jumping animals SUTTON, GP; University of Lincoln RScealai@gmail.com Borelli’s law is 500 year-old constraint on how high an animal can jump. The argument is simple, as animals get larger, their ability to generate mechanical energy and their mass both go up at the […]
The power of extreme movement evolution, behavior, and biomechanics of mantis shrimp strikes
Meeting Abstract S3-7 Friday, Jan. 4 11:30 – 12:00 The power of extreme movement: evolution, behavior, and biomechanics of mantis shrimp strikes PATEK, S. N.; Duke University snp2@duke.edu http://www.thepateklab.org The biomechanics of fast mantis shrimp (Stomatopoda) strikes involves an uneven and extreme flow of energy from muscle contraction, spring-loading, latch-release, to a final, intense impact. Slowly-contracting, force-modified […]
The Role of Water in Effecting Rapid Movements in Plants
Meeting Abstract S3-3 Friday, Jan. 4 09:00 – 09:30 The Role of Water in Effecting Rapid Movements in Plants EDWARDS, J; Williams College jedwards@williams.edu Plants lack muscles, yet can carry out extraordinarily rapid movements in the order of milliseconds or less. Many of these ultra fast movements are mediated by water. Here I compare the rapid movements […]

Meeting Abstract S3-9 Friday, Jan. 4 14:00 – 14:30 Suction feeding without muscles: Estimating power requirements from flow for the traps of bladderwort, a carnivorous plant MüLLER, UK*; BROWN, MD; BERG, O; California State University Fresno; California State University Fresno; California State University Fresno umuller@csufresno.edu http://zimmer.csufresno.edu/~umuller/FBDS/FBDS-home/FBDS-home-welcome.html Suction feeding is the most common feeding mode in large aquatic […]
Some Challenges of Playing with Power
Meeting Abstract S3-2 Friday, Jan. 4 08:30 – 09:00 Some Challenges of Playing with Power ROBERTS, TJ; Brown University thomas_roberts@brown.edu http://www.brown.edu/research/labs/robertslab/ Many studies of the flow of energy between the body, muscles, and elastic elements highlight advantages of the storage and recovery of elastic energy. The spring-like action of structures associated with muscles allows for movements that […]
Pivots and power amplification evolution and functional morphology of feeding in seahorses and their relatives
Meeting Abstract S3-11 Friday, Jan. 4 15:00 – 15:30 Pivots and power amplification: evolution and functional morphology of feeding in seahorses and their relatives LONGO, SJ; Duke University sjl53@duke.edu https://sarahjlongo.wordpress.com Power-amplified mechanisms (PAMs) have evolved multiple times independently across the tree of life and allow organisms to increase performance during a diverse array of fitness-related behaviors. PAMs […]
Making an impact Energy transmission during high-speed puncture events
Meeting Abstract S3-8 Friday, Jan. 4 13:30 – 14:00 Making an impact: Energy transmission during high-speed puncture events ANDERSON, P. S. L. *; CROFTS, S. B.; Univ. of Illinois, Urbana-Champaign; Univ. of Illinois, Urbana-Champaign andersps@illinois.edu An organism’s ability to control the timing and direction of energy flow within its body is vital to maintaining proper function. But […]
