Power-amplified feeding in snipefish (Macroramphosus scolopax)
Meeting Abstract 113-5 Thursday, Jan. 7 11:15 Power-amplified feeding in snipefish (Macroramphosus scolopax) LONGO, S.J.; University of California, Davis sjlongo@ucdavis.edu https://sarahjlongo.wordpress.com Nearly all syngnathiforms (seahorses, pipefishes, and their relatives) are characterized by a long snout, which they employ in an unusual motion called pivot feeding, or rapid dorsal rotation of the head to bring the mouth closer […]

Jordan HS, Durham, NC rodya01@yahoo.com http://www.philipslanderson.com/ Jellyfish using their nematocysts to inject venom, mantis shrimp harpooning passing fish, and hunters shooting with bow and arrows are all examples of a […]
Evidence of a high-power feeding mechanism in salamandrid salamanders
Meeting Abstract 113-2 Thursday, Jan. 7 10:30 Evidence of a high-power feeding mechanism in salamandrid salamanders STINSON, C.M.*; DEBAN, S.M.; University of South Florida, Tampa; University of South Florida, Tampa cstinson@mail.usf.edu Differences in morphology between closely related species are known to impact function and consequently affect organismal performance. The diverse hyobranchial apparatus morphologies of salamanders enable varying […]

Meeting Abstract 113-7 Sunday, Jan. 8 09:30 – 09:45 Thermal dependence of sprint performance and critical thermal limits in ecologically distinct populations of a small ectotherm NEEL, LK*; MCBRAYER, LD; Georgia Southern University, Statesboro ; Georgia Southern University, Statesboro lauren_k_neel@georgiasouthern.edu Ectotherms are thought to be particularly vulnerable to the effects of anthropogenic climate change as they perform […]
Role of Genetic Variation on the Ontogeny of Metabolism during Development
Meeting Abstract 113-4 Sunday, Jan. 8 08:45 – 09:00 Role of Genetic Variation on the Ontogeny of Metabolism during Development. MATOO, OB*; JULICK, CR; MONTOOTH, KL; University of Nebraska, Lincoln omatoo2@unl.edu Reprogramming of the core metabolism may be necessary during development of many holometabolous insects to generate sufficient energy for maintenance and meet demands of rapid […]

Meeting Abstract 113-6 Sunday, Jan. 8 09:15 – 09:30 Respiratory turbinate surface area is not affected by adaptation to high-altitude hypoxia in deer mice OWERKOWICZ, T.*; IVY, C.M.; SCOTT, G.R.; CSUSB; McMaster; McMaster towerkow@csusb.edu Respiratory turbinates – maxillo- and nasoturbinal bones in the nasal cavity of mammals – have been proposed as anatomic correlates of endothermy in […]
Optimal Foraging Frequency and its Physiological “Brackets” in Ectotherms
Meeting Abstract 113-2 Sunday, Jan. 8 08:15 – 08:30 Optimal Foraging Frequency and its Physiological “Brackets” in Ectotherms WATSON, CM; Midwestern State University charles.watson@mwsu.edu http://www.charlesmwatson.com Feeding frequency in ectotherms can vary based upon both intrinsic and extrinsic factors, including food size and availability, developmental state, body condition, life history, and season. Optimal Foraging Theory, if extended to […]
Links between ovary status, sensory perceptions and foraging in a socially plastic bee
Meeting Abstract 113-1 Sunday, Jan. 8 08:00 – 08:15 Links between ovary status, sensory perceptions and foraging in a socially plastic bee IHLE, KE; Smithsonian Tropical Research Institute kateihle@gmail.com The ground plan hypotheses of social evolution argue that the complex divisions of labor observed in eusocial insect societies evolved via the compartmentalization of linked components of an […]
