Optimizing selection for function-valued traits
Journal of Mathematical Biology, 2007We consider a function-valued trait z(t) whose pre-selection distribution is Gaussian, and a fitness function W that models optimizing selection, subject to certain natural assumptions. We show that the post-selection distribution of z(t) is also Gaussian, compute the selection differential, and derive an equation that expresses the selection gradient ...

Pulmonary Function in Sickle Cell Trait
Annals of Internal Medicine, 1987Pulmonary function abnormalities, which have been reported to occur in persons with sickle cell trait (hemoglobin AS), could intensify the hypoxic stimulus for the systemic formation of sickle cells at high altitude. We sought to determine whether pulmonary function abnormalities occur as a result of exposure to high altitudes in persons with ...

Resting Brain Functional Networks and Trait Coping
Brain Connectivity, 2018This study aims to investigate the effects of individual differences in trait coping on brain networks at rest using electroencephalography (EEG) data. EEG recordings were processed using graph theory analysis. Active and passive coping styles were determined according to the factor structure of the Brief Coping Orientation to Problems Experienced ...

Microbially Mediated Plant Functional Traits
Annual Review of Ecology, Evolution, and Systematics, 2011Plants are rife with bacteria and fungi that colonize roots and shoots both externally and internally. By providing novel nutritional and defense pathways and influencing plant biochemical pathways, microbes can fundamentally alter plant phenotypes. Here we review the widespread nature of microbially mediated plant functional traits. We highlight that

A meta-analysis of zooplankton functional traits influencing ecosystem function
Ecology, 2015AbstractThe use of functional traits to characterize community composition has been proposed as a more effective way to link community structure to ecosystem functioning. Organismal morphology, body stoichiometry, and physiology can be readily linked to large‐scale ecosystem processes through functional traits that inform on interspecific and species ...

Trait Extraversion and Dopamine Function
Social and Personality Psychology Compass, 2015Abstract An influential theory within personality neuroscience suggests that trait extraversion is underpinned by individual differences in dopamine function. In a review of the relevant literature, we evaluate this theory in light of the evidence from molecular genetics, neuroimaging, and psychopharmacology.

Abstract In the extensive literature on what it means for a biological trait to have a function, philosophers and biologists have given the notion of function star billing. They have paid little attention to the notion of trait appearing in the supporting role. My goal in this chapter is to turn the spotlight onto this fundamental notion

Functional traits and trait diversity of leaves: palaeoecological perspectives
Functional traits were originally defined as any characteristic of an organism that contributes to fitness. From this autecological perspective, trait-based research has considerably expanded into approaches of ecosystem analysis that also have high potential for palaeoecological research.Anita Roth-Nebelsick +1 more
