Dynamic stability during quadrupedal arboreal locomotion Body segment contributions to angular momentum
Meeting Abstract 79.3 Friday, Jan. 6 Dynamic stability during quadrupedal arboreal locomotion: Body segment contributions to angular momentum LAMMERS, A. R.*; ZURCHER, U.; School of Health Sciences, Cleveland State University; Department of Physics, Cleveland State University a.Lammers13@csuohio.edu Traveling on narrow tree branches and twigs presents a challenge to maintaining balance and avoiding falls. To remain stable while […]
Survival under pressure lethal and sublethal effects of an invasive predator, the red imported fire ant, on a spiny lizard
Meeting Abstract 78.2 Friday, Jan. 6 Survival under pressure: lethal and sublethal effects of an invasive predator, the red imported fire ant, on a spiny lizard THAWLEY, C.J.*; ROBBINS, T.R.; LANGKILDE, T.; Pennsylvania State University cjt171@psu.edu Environmental interactions play a major role in structuring communities and determining the life histories of species. Anthropogenic impacts, such as climate […]
Sponsorship required for permanent residency in sediment
Meeting Abstract 78.9 Friday, Jan. 6 Sponsorship required for permanent residency in sediment LI, Jingchun; University of Michigan, Ann Arbor jingchun@umich.edu The importance of biotic associations in the evolution of marine taxa is implicitly understood. However, relative to terrestrial systems, meaningful hypotheses and tests of specific mechanisms are underdeveloped. The marine bivalve superfamily Galeommatoidea represents an ideal […]

Fine tuning anti-predator responses are the costs of inducible predator defences proportional to the magnitude of the responses
Meeting Abstract 78.1 Friday, Jan. 6 Fine tuning anti-predator responses: are the costs of inducible predator defences proportional to the magnitude of the responses? HEINIGER, J*; VAN UITREGT, V; WILSON, R S; University of Queensland; University of Queensland; University of Queensland r.wilson@uq.edu.au The threat-sensitive predator avoidance hypothesis predicts the magnitude of inducible defensive responses should reflect the […]

Meeting Abstract 78.3 Friday, Jan. 6 Ecological opportunity and competition predict widespread disruptive selection in the wild MARTIN, R.A.*; PFENNIG, D.W.; Univ. of North Carolina, Chapel Hill; Univ. of North Carolina, Chapel Hill ryan_martin@ncsu.edu Disruptive selection occurs in a population when two or more modal phenotypes have higher fitness than the intermediate phenotypes between them. Such selection […]
