Meeting Abstract 5.4  Saturday, Jan. 4 08:45  The Role of Guitarfish in the Origin of Skates and Rays CLAESON, KM*; ASCHLIMAN, NC; UNDERWOOD, CJ; PCOM; St. Ambrose University; Birkbeck College kerincl@pcom.edu Recent phylogenetic analyses based on molecular data, paleontological data, or extant morphology consistently recovered a paraphyletic “Rhinobatiformes” (guitarfishes) but disagreed on the position of their close […]

Meeting Abstract 5.6  Saturday, Jan. 4 09:15  The Effects of Diet, Ecology, and Physiology on the Evolution of Endothermic Gastrointestinal Tract Lengths LINSCOTT, T.M.*; ROCHE, E.; BONETT, R.M.; University of Tulsa; University of Minnesota; University of Tulsa mason-linscott@utulsa.edu Vertebrates have diversified into a wide range of habitats, and consume many forms of organic material. Consequently, vertebrates have […]

Meeting Abstract 5.1  Saturday, Jan. 4 08:00  Morphological integration in the forelimb of musteloid carnivorans FABRE, A.-C.*; GOSWAMI, A.; PEIGNé, S.; CORNETTE, R.; MNHN/UCL; UCL; MNHN; MNHN fabreac@gmail.com The forelimb forms a functional unit that allows a variety of behaviours and needs to be mobile, yet at the same time stable. Both mobility and stability are controlled […]

Meeting Abstract 5.3  Saturday, Jan. 4 08:30  Body and fin shape evolution in cichlid fishes FEILICH, K.L.; Harvard University, Cambridge, MA kfeilich@fas.harvard.edu Cichlid fishes (Acanthomorpha: Cichlidae) are some of the most morphologically and behaviorally diverse fishes in the world. Their morphological disparity, especially of feeding structures, is well-documented. Despite this, comparatively little is known about how swimming […]

Meeting Abstract 5.2  Sunday, Jan. 4 08:15  Ventilation behavior in honeybees: Linking biomechanics and group behavior PETERS, JM*; GRAVISH, N; COMBES, SA; Harvard University jcbptrs@gmail.com Honeybees exhibit fine control of the microclimate inside their nests. For example, nest temperature is maintained at approximately 36 degrees Celsius despite drastic fluctuations in ambient temperature. When temperature inside the nest […]

Meeting Abstract 5.3  Sunday, Jan. 4 08:30  The contribution of the branchiostegal apparatus to driving ventilatory current in cottoid fishes FARINA, S.C.*; FERRY, L.A.; KNOPE, M; SUMMERS, A.P.; BEMIS, W.E.; Cornell University; Arizona State University; Stanford University; Friday Harbor Laboratories; Cornell University scf59@cornell.edu The branchiostegal apparatus forms the ventro-lateral wall of the gill chamber of ray-finned fishes […]

Meeting Abstract 5.1  Sunday, Jan. 4 08:00  The Madagascar hissing cockroach modulates abdominal pump frequency and spiracle phasing to compensate for hypoxia GARRETT, J*; SOCHA, JJ; Virginia Tech; Virginia Tech jfg@vt.edu http://www.joelgarrett.com All insects use pressure gradients produced by metabolism to move gas diffusively through an internal tracheal system. Some species augment this gas exchange using tracheal […]

Meeting Abstract 5.7  Sunday, Jan. 4 09:30  Physical and Computational Hemodynamics Models for the Artiodactyl Carotid Rete O’BRIEN, HD*; BOURKE, J; Ohio University haley.d.obrien@gmail.com In the mammalian order Artiodactyla, the majority of arterial blood entering the cranial cavity is supplied by a large arterial meshwork, the carotid rete, which functionally replaces the internal carotid artery. Extensive experimentation […]

Meeting Abstract 5.5  Sunday, Jan. 4 09:00  Functional compartmentalization in the hemocoel of the American locust ADJERID, K*; PENDAR, H; HARRISON, J.F.; SOCHA, J.J.; Virginia Tech; Virginia Tech; Arizona State University; Virginia Tech adjerid@vt.edu http://https://sites.google.com/site/kadjerid/ The hemocoel of insects is often considered as an open compartment in which hemolymph is free to flow, particularly in insects lacking […]

Meeting Abstract 5.4  Sunday, Jan. 4 08:45  Force-displacement measurements of pit membranes in gymnosperms ZELINKA, S.L.; BOURNE, K.J.; GLASS, S.V.; HERMANSON, J.C.*; WIEDENHOEFT, A.C.; USFS Forest Products Laboratory; USFS Forest Products Laboratory; USFS Forest Products Laboratory; USFS Forest Products Laboratory; USFS Forest Products Laboratory jhermans@wisc.edu The fluid-structure behavior of the torus-margo pit structure in bordered pits has […]
