Jumping without slipping spiders need sticky feet for take-off
Meeting Abstract 88.4 Sunday, Jan. 6 Jumping without slipping: spiders need sticky feet for take-off GOETZKE, H.H.*; FEDERLE, W.; University of Cambridge; University of Cambridge hhg24@cam.ac.uk Many insects and spiders can perform rapid jumps from smooth plant surfaces. If jumping arthropods relied only on classic friction, they should slip on smooth surfaces except for very steep take-offs. […]
Joint contributions to locomotor velocity and power in Iguana iguana
Meeting Abstract 88.3 Sunday, Jan. 6 Joint contributions to locomotor velocity and power in Iguana iguana ALLEN, V*; NYAKATURA, J; Univ.of Jena; Univ.of Jena mrvivianallen@gmail.com In ‘Sprawling’ locomotion (e.g. lizards and salamanders), 3D limb kinematics appear more important than the more planar motions of ‘upright’ animals. In particular, due to the highly abducted proximal limb segment […]
Comparison of walking mechanics in an arboreal and a terrestrial primate
Meeting Abstract 88.1 Sunday, Jan. 6 Comparison of walking mechanics in an arboreal and a terrestrial primate BISHOP, K.L.*; O’NEILL, M.; SCHMITT, D.; Florida International University; Stony Brook University; Duke University kristin.bishop@fiu.edu Animals have several mechanisms available that may reduce their muscular effort while walking. One is to adopt an inverted pendulum movement of center of mass […]
Separating the effects of the deposition substrate and habitat on the anti-microbial properties of egg masses of Haminoea vesicula
Meeting Abstract 87.4 Sunday, Jan. 6 Separating the effects of the deposition substrate and habitat on the anti-microbial properties of egg masses of Haminoea vesicula SMOOT, S.C.*; PLANTE, C.J.; PODOLSKY, R.D.; College of Charleston; College of Charleston; College of Charleston scsmoot@gmail.com Several marine invertebrates reproduce by encapsulating embryos inside gelatinous egg masses until hatching. Previous studies have […]
Plasticity in Hatching in Response to Predators and Individual Variation in Duration, Frequency, and Seasons of Brooding in the Barnacle Balanus glandula
Meeting Abstract 87.5 Sunday, Jan. 6 Plasticity in Hatching in Response to Predators and Individual Variation in Duration, Frequency, and Seasons of Brooding in the Barnacle Balanus glandula STRATHMANN, R.R.*; BRANSCOMB, E.S.; VEDDER, K.; Univ. of Washington, Friday Harbor rrstrath@u.washington.edu Hatching in response to predation reduces a potential cost of holding larvae until conditions in the plankton […]
Molecular and Morphological Description of Stomatopod Larvae
Meeting Abstract 87.1 Sunday, Jan. 6 Molecular and Morphological Description of Stomatopod Larvae FELLER, KD*; PORTER, ML; CRONIN, TW; UMBC; University of South Dakota; UMBC kfeller1@umbc.edu The stomatopod larval phase is adapted for survival in the pelagic environment. Larvae have thus evolved an overall morphology that is separate from the adult, making them difficult to identify since […]
Egg size and exogenous food level interact to affect larval growth in tropical Echinometra spp sea urchins
Meeting Abstract 87.2 Sunday, Jan. 6 Egg size and exogenous food level interact to affect larval growth in tropical Echinometra spp. sea urchins MCALISTER, J/S*; MORAN, A/L; College of the Holy Cross; Clemson University jmcalist@holycross.edu Planktotrophic larvae of marine invertebrates develop and grow by utilizing energy and materials from a combination of maternally-supplied endogenous egg reserves and […]
Signal plasticity and mate recognition in the pine woods treefrog, Hyla femoralis
Meeting Abstract 86.2 Sunday, Jan. 6 Signal plasticity and mate recognition in the pine woods treefrog, Hyla femoralis MERRICKS, J.A.*; GERHARDT, H.C.; Univ. of Missouri, Columbia; Univ. of Missouri, Columbia jawfz2@mail.missouri.edu Both female preference and male competition shape the evolution of acoustic sexual signals. In the complex acoustic environment of anuran breeding aggregations, signalers are challenged to […]
Rescuing of call attractiveness using novel acoustic appendages in gray treefrogs, Hyla versicolor
Meeting Abstract 86.3 Sunday, Jan. 6 Rescuing of call attractiveness using novel acoustic appendages in gray treefrogs, Hyla versicolor HENDERSON, J.J.*; GERHARDT, H.C.; University of Missouri, Columbia; University of Missouri, Columbia jhenderson@mail.missouri.edu Acoustic signals vary from simple, repeated elements to a combination of diverse elements that create a complex signal. Complex calls are found in a variety […]
