Ingestion and allocation of macronutrients underlying reduced reproduction and life extension in grasshoppers
Meeting Abstract S9.3-2 Tuesday, Jan. 7 14:00 Ingestion and allocation of macronutrients underlying reduced reproduction and life extension in grasshoppers HATLE, JD; Univ. of North Florida jhatle@unf.edu Reduced reproduction and reduced diet (aka. dietary restriction) each extend lifespan in many animals. Because the degree of dietary restriction needed to extend lifespan usually reduces fecundity, the dogma has […]
Ecological Immunology of Woolly Bear Caterpillars
Meeting Abstract S9.3-3 Tuesday, Jan. 7 14:30 Ecological Immunology of Woolly Bear Caterpillars SINGER, M.S.*; MASON, P.A.; SMILANICH, A.M.; Wesleyan University; U. Colorado, Boulder; U. Nevada, Reno msinger@wesleyan.edu The emerging field of ecological immunology recognizes the role of an organism’s environment in its ability to defend itself against parasites. One important mechanism of ecological immunology is medication […]
Costs of Income Versus Capital Provisioning of Nutrients for Immune Defenses in Birds
Meeting Abstract S9.1-4 Tuesday, Jan. 7 09:10 Costs of Income Versus Capital Provisioning of Nutrients for Immune Defenses in Birds KLASING, K. C.; Univ. California, Davis kcklasing@ucdavis.edu An important life history variable is recognized between species that provision offspring using energy gained concurrently (income breeders) and those that provision offspring using energy stores accumulated at an earlier […]
Bulk tissue and amino acid δ13C analysis shows that mice can use dietary lipids to build proteinaceous tissues
Meeting Abstract S9.1-3 Tuesday, Jan. 7 08:40 Bulk tissue and amino acid δ13C analysis shows that mice can use dietary lipids to build proteinaceous tissues NEWSOME, Seth D.*; WOLF, Nathan; FOGEL, Marilyn L.; University of New Mexico; University of Alaska–Anchorage; University of California–Merced newsome@unm.edu Understanding the mechanisms that govern the incorporation and routing of macronutrients from dietary […]
A beginner’s guide to nutritional profiling in physiology and ecology
Meeting Abstract S9.2-3 Tuesday, Jan. 7 11:30 A beginner’s guide to nutritional profiling in physiology and ecology FROST , Paul C*; WAGNER, Nicole D; Trent University; Trent University paulfrost@trentu.ca The nutritional history of an organism is often inherently difficult to ascertain. This information on past diet is particularly important when explaining the role of nutrition in physiological […]
The role of pre-existing plasticity in adaptive evolution
Meeting Abstract S8.1-2 Monday, Jan. 6 08:30 The role of pre-existing plasticity in adaptive evolution SERRATO-CAPUCHINA, G.A.; PFENNIG, D.W.*; Univ. of North Carolina, Chapel Hill; Univ. of North Carolina, Chapel Hill dpfennig@unc.edu In order for adaptive evolution to occur, phenotypic variation must be present on which selection can act. Yet, relatively little is known about the source(s) […]
The importance of fluctuating temperatures for offspring phenotype in turtles with temperature-dependent sex determination
Meeting Abstract S8.2-1 Monday, Jan. 6 10:30 The importance of fluctuating temperatures for offspring phenotype in turtles with temperature-dependent sex determination BOWDEN, RM*; PAITZ, RT; Illinois State University; University of Illinois rmbowde@ilstu.edu In species with temperature-dependent sex determination (TSD), the temperatures experienced during incubation are correlated with the resultant sex of the offspring. It has also been […]
The evolution of within- and among generation phenotypic plasticity in natural populations of Daphnia
Meeting Abstract S8.1-4 Monday, Jan. 6 09:30 The evolution of within- and among generation phenotypic plasticity in natural populations of Daphnia WALSH, M.R.; Univ of Texas, Arlington matthew.walsh@uta.edu Many environmental forces (invasive species, climate change, habitat loss) threaten native biodiversity. The mechanisms that permit persistence, such as the ability of organisms to evolve genetically or alter the […]
