Demographic, developmental and life-history variation across altitude in Erysimum capitatum
1. Natural variation in life history provides the opportunity to examine its correlated population performance. Alpine systems are considered to be vulnerable to climate change as high-altitude conditions are predicted to become more similar to those at low altitude. Comparing natural populations that exhibit variation in life history across altitude can provide information on how life history ...
متن کاملPopulation differentiation and plasticity in vegetative ontogeny: effects on life-history expression in Erysimum capitatum (Brassicaceae).
PREMISE OF THE STUDY Distinguishing the contributions of phenotypic plasticity vs. population differentiation to variation in the life history of plants throughout their range is important for predicting their performance after dispersal or their responses to environmental change. In Erysimum capitatum, plants in alpine environments are iteroparous perennials, but those below tree line are seme...
متن کاملLocal adaptation and plasticity of Erysimum capitatum to altitude: its implications for responses to climate change
1. Alpine plants are at high risk because of climate change. Assessing the performance of alpine plant species across different altitudes is useful for predicting how they may respond to changing climate. Adaptation and plasticity of early life stages are of particular interest since seed germination and seedling establishment could be crucial life-history stages for environmental tracking and ...
متن کاملA demographic model explains life-history variation in Arabis fecunda
1. The distinction between semelparity and iteroparity is one of the most fundamental in life-history biology. Despite an abundance of theory proposed to explain the evolution of this dichotomy, few quantitative empirical tests exist. 2. We report here on life-history variation in the perennial herb Arabis fecunda (Brassicaceae), in which differences in the frequency of iteroparity and terminal...
متن کاملintraspecific variation in pelophylax ridibunda (rana ridibunda) in southern iran: life history and developmental patterns
this study describes the influences of variations in life history traits and developmental patterns of pelophylax ridibunda. the causes of this variation were investigated by comparing observed patterns of interpopulational differences from geographic variables. the aim of the study was to investigate whether embryos and larvae from different populations of p. ridibunda show the same pattern of...
