Meeting Abstract 59.1 Tuesday, Jan. 6 Revisiting the niche: when is a mammalian herbivore a specialist? SHIPLEY, Lisa A.*; FORBEY, Jennifer; Washington State University; Boise State University shipley@wsu.edu Although dietary specialization is considered rare in mammalian herbivores, examining the causes and consequences of the breadth of their feeding niche is critical for understanding selective pressures in diet […]

Historical constraints on host use in herbivorous marine amphipods
Meeting Abstract 59.4 Tuesday, Jan. 6 Historical constraints on host use in herbivorous marine amphipods POORE, A G B*; SOTKA, E E; University of New South Wales; College of Charleston a.poore@unsw.edu.au It is commonly assumed that marine herbivores are relatively unspecialised consumers, lacking the strong historical associations between herbivore and plant taxa that are evident among terrestrial […]
Catechol-O-methyl transferase may play an important role in allowing Neotoma stephensi to specialize on juniper
Meeting Abstract 59.6 Tuesday, Jan. 6 Catechol-O-methyl transferase may play an important role in allowing Neotoma stephensi to specialize on juniper SKOPEC, MM*; NEBEKER, C; DEARING, MD; Weber State University; Weber State University; University of Utah micheleskopec@weber.edu Dietary specialization is thought to be rare in mammalian herbivores because of limitations of their detoxification system in processing large […]
A coevolutionary arms-race between macroalgae and herbivores are tropical herbivores more tolerant of lipophilic secondary metabolites than temperate herbivores
Meeting Abstract 59.3 Tuesday, Jan. 6 A coevolutionary arms-race between macroalgae and herbivores: are tropical herbivores more tolerant of lipophilic secondary metabolites than temperate herbivores? CRAFT, J.D.*; PAUL, V.J.; SOTKA, E.E.; The College of Charleston; Smithsonian Marine Station ; The College of Charleston craftjd@gmail.com In contrast to temperate seaweeds, tropical macroalgae produce a greater diversity and higher […]

One of the best examples has been latitudinal […]
Regulation of Methyl Farnesoate Esterase during development of the tadpole shrimp, Triops longicaudatus
Meeting Abstract 59.2 Wednesday, Jan. 6 Regulation of Methyl Farnesoate Esterase during development of the tadpole shrimp, Triops longicaudatus GLEDHILL, Michael R*; TRAN, Michael C; TSUKIMURA, Brian; California State Univ., Fresno mrgledhi@csufresno.edu Methyl farnesoate (MF), a putative crustacean hormone, is well documented as the precursor to juvenile hormone in insects. In crustaceans, MF promotes juvenile morphology, with […]
Novel mechanisms regulating a sexual signal testosterone inhibition of pheromone production in red-sided garter snakes
Meeting Abstract 59.3 Wednesday, Jan. 6 Novel mechanisms regulating a sexual signal: testosterone inhibition of pheromone production in red-sided garter snakes PARKER, M ROCKWELL*; MASON, ROBERT T; Oregon State Univ., Corvallis parkermi@science.oregonstate.edu Most vertebrates coordinate reproduction using multiple signals, but species that utilize single signals to encode multiple pieces of information are powerful models for understanding the […]
Hormonal correlates accompanying reproductive behavior in three species of python
Meeting Abstract 59.5 Wednesday, Jan. 6 Hormonal correlates accompanying reproductive behavior in three species of python BRASHEARS, J.A.*; DENARDO, D.F.; Arizona State University jake.brashears@asu.edu Parental care, while ubiquitous among mammals and birds, is also common in ectothermic vertebrates. The examination of parental care across major taxa sheds light on the physiological context within which it evolves. Pythonidae […]
