متن کاملUrban birds have broader environmental tolerance.
Urbanization dramatically changes the composition and diversity of biotic communities. The characteristics distinguishing species that persist in urban environments, however, are poorly understood. Here we test the hypothesis that broadly adapted organisms are better able to tolerate urbanization, using a phylogenetically controlled, global comparison of birds. We compared elevational and latit...
متن کاملThe selective advantage of reaction norms for environmental tolerance
A tolerance curve defines the dependence of a genotype’s fitness on the state of an environmental gradient. It can be characterized by a mode (the genotype’s optimal environment) and a width (the breadth of adaptation). It seems possible that one or both of these characters can be modified in an adaptive manner, at least partially, during development. Thus, we extend the theory of environmental...
متن کاملEnvironmental and Biopsychosocial Factors Associated with Financial Risk Tolerance
The effects of environmental and biopsychosocial factors on financial risk tolerance is analyzed. The research is premised on Irwin’s (1993) risk-taking behavioral model. Findings from an OLS regression, using a sample of faculty and staff from two universities (N = 406), indicate that education, marital status, net worth, financial knowledge, and household income, as environmental factors, are...
متن کاملEnvironmental tolerance, heterogeneity, and the evolution of reversible plastic responses.
Phenotypic plasticity is a key factor for the success of organisms in heterogeneous environments. Although many forms of phenotypic plasticity can be induced and retracted repeatedly, few extant models have analyzed conditions for the evolution of reversible plasticity. We present a general model of reversible plasticity to examine how plastic shifts in the mode and breadth of environmental tol...
