Cryptic Plumage Dimorphism in Aphelocoma Scrub-Jays Assessing Visible and Ultraviolet Reflectance Across Species and Subspecies
HYLTON, J.H.*; BRIDGE, E.S.; GAMBLE, L.G.; SCHOECH, S.J.; University of Memphis; University of Memphis; University of Memphis; University of Memphis: Cryptic Plumage Dimorphism in Aphelocoma Scrub-Jays: Assessing Visible and Ultraviolet Reflectance Across Species and Subspecies Recent studies of avian vision and plumage coloration have revealed a surprising degree of cryptic sexual dimorphism, with many examples […]
The Scaling of Constriction Strength Snakes
MEHTA, Rita; MOON, Brad*; UC Davis; University of Louisiana: The Scaling of Constriction Strength Snakes Constriction was probably one of the key innovations that enabled snakes to subdue relatively large prey animals. It involves a snake placing its body around a prey animal and squeezing, which restrains the prey from escaping and defending itself, and […]

Springs, linkages and latches a mechanical model of the mantis shrimps raptorial appendage
PATEK, Sheila N.*; BAIO, Joseph; SUMMERS, Adam; Univ. of California, Berkeley; Univ. of California, Berkeley; Univ. of California, Irvine: Springs, linkages and latches: a mechanical model of the mantis shrimp�s raptorial appendage Mantis shrimp (Stomatopoda) use a remarkable spring-loaded click mechanism in their raptorial appendages to rapidly capture and process prey. In some mantis shrimp […]
Sinking in Sand – An Examination of Burrowing in Sea Cucumbers (Holothuroidea Echinodermata)
SPAIN, D. D. *; PERALTA, M.; Dominican University of California: Sinking in Sand – An Examination of Burrowing in Sea Cucumbers (Holothuroidea: Echinodermata) There are over 1,400 species of sea cucumbers living in marine environments worldwide. Yet, there are few descriptions of the burrowing process of infaunal holothuroids. This study provides a detailed description of […]
Radiolarian diversity and morphology structural adaptations to the deep sea
HADDOCK, S.H.D; MBARI: Radiolarian diversity and morphology: structural adaptations to the deep sea Radiolarians are marine protists that form intricate siliceous “skeletons”. Although these forms have drawn attention since the 19th century, currently radiolarians are most familiar to paleontologists and marine geologists who study their sedimented remains. The natural history of living species, especially of […]
Mechanical properties of a crab skeleton following molting
TAYLOR, J. R. A.*; KIER, W. M.; Univ. of North Carolina, Chapel Hill; Univ. of North Carolina, Chapel Hill: Mechanical properties of a crab skeleton following molting Molting involves significant changes in the structure of the exoskeleton as the old one is shed and a new one is secreted. The flimsy new cuticle takes several […]
Mechanical Properties of Embioptera Silk
COLLIN, M. A.*; SWANSON, B. O.; HAYASHI, C. Y.; Univ. of California, Riverside ; Pacific University, Oregon; Univ. of California, Riverside: Mechanical Properties of Embioptera Silk Arthropods produce and use silk for a variety of purposes. Silk from a few types of arthropods have been mechanically tested and some of these silks were found to […]
Evolution of Constriction Motor Patterns in Snakes
MEHTA, Rita; Univ. of California, Davis: Evolution of Constriction Motor Patterns in Snakes Behavior results from the integration of morphology, physiology, and biomechanics. Any one of these levels can be examined to gain insight into patterns driving behavioral variation across species. My research takes an integrative approach to test hypotheses concerning the evolution of constriction […]
