Meeting Abstract 20.1  Tuesday, Jan. 4  Surface dependent attachment in fluid-based smooth adhesive pads of insects DIRKS, JH*; FEDERLE, W; Trinity College Dublin; University of Cambridge jan-henning.dirks@tcd.ie Smooth adhesive pads of many insects adhere via nanometre-thin films of a two-phasic fluid. This fluid fills in gaps between the pad and the surface, thereby maximises contact area and […]

Meeting Abstract 20.3  Tuesday, Jan. 4  Slipping, sliding, and stability: locomotor strategies for overcoming unexpected low-friction surfaces CLARK, A.J.*; HIGHAM, T.E.; College of Charleston; Clemson University clarkaj@cofc.edu Legged terrestrial animals must maintain dynamic stability while negotiating unexpected perturbations inherent to their structurally complex environments. Among humans, fatal and nonfatal injuries frequently result from slip-induced falls precipitated by […]

Meeting Abstract 20.5  Tuesday, Jan. 4  How gait influences obstacle negotiation in lizards: Is bipedal better? OLBERDING, J.P.*; HIGHAM, T.E.; MCBRAYER, L.D.; Clemson University; Clemson University; Georgia Southern University jpolber@clemson.edu Bipedal locomotion is common in many species of lizard, especially those that live in open habitats such as deserts. However, the advantages of this gait are still […]

Meeting Abstract 20.6  Tuesday, Jan. 4  Dogs on springs: do trotting dogs adjust their virtual leg stiffness on compliant surfaces? WILSHIN, S.*; KELLEHER, C.N.; BYRNES, G.; SEIPEL, J.; SPENCE, A.J.; Royal Veterinary College; RVC; University of Cincinnati; Purdue University; RVC swilshin@rvc.ac.uk Hierarchical hypotheses of motor control posit that animals overcome the problem of controlling complex bodies by […]

Meeting Abstract 20.2  Tuesday, Jan. 4  Attachment in smooth insect pads: the influence of surface energy LABONTE, D.*; BULLOCK, J. M. R.; FEDERLE, W.; University Of Applied Sciences, Bremen; Dept. of Zoology, University of Cambridge; Dept. of Zoology, University of Cambridge labontedavid@web.de All insects studied to date adhere to surfaces via small amounts of fluid secreted into […]

Meeting Abstract 19.2  Tuesday, Jan. 4  The contribution of anti-parasite behavior to resistance and tolerance of trematode infections in anuran tadpoles SEARS, B.F.*; ROHR, J.R.; MARTIN, L.B.; University of South Florida; University of South Florida; University of South Florida bsears@mail.usf.edu Hosts can cope with parasites utilizing two strategies: resistance, which reduces the intensity of an infection, and/or […]

Meeting Abstract 19.1  Tuesday, Jan. 4  Ontogenetic changes in immunity in Mormon crickets SRYGLEY, R.B.**; , ; USDA-Agricultural Research Service robert.srygley@ars.usda.gov Immune defenses confer protection from wounding and invasion. A trade-off between allocation of resources to growth or defense is well known in many plants, but it is much less explored in insects. Mormon crickets (a katydid) […]

Meeting Abstract 19.5  Tuesday, Jan. 4  Fitness consequences of a parasite specific immune response in Darwin’s finches KOOP, Jennifer AH*; KNUTIE, Sarah A; OWEN, Jeb P; CLAYTON, Dale H; Univ. of Utah; Univ. of Utah; Washington State Univ.; Univ. of Utah jennifer.koop@utah.edu The immune system has evolved as a defense mechanism for hosts against their parasites and […]

Meeting Abstract 19.6  Tuesday, Jan. 4  Exploring the effects of pregnancy on Th1/Th2 immune tradeoffs in the African buffalo O’NEAL, D.M.*; JOLLES, A.E.; EZENWA, V.O.; University of Georgia; Oregon State University; University of Georgia dmoneal@uga.edu Reproduction is costly and requires significant maternal investment. This investment increases as pregnancy progresses and maternal resources are allocated to fetal development […]

Meeting Abstract 19.4  Tuesday, Jan. 4  Ectoparasite Removal Improves Reproductive Success And Body Condition In A Territorial Tree Squirrel PATTERSON, J. E. H.; University of Calgary jesse.patterson@ucalgary.ca Parasites are widely considered to be detrimental to the fitness of their hosts; however, the actual costs of parasitism on host fitness are rarely quantified. I experimentally removed ectoparasites from […]
