Resistance to metal contamination by historically-stressed populations of Ceriodaphnia pulchella: environmental influence versus genetic determination.

Field populations of daphnids historically-stressed by metal contamination may show increased resistance to those contaminants. This study was undertaken aiming to confirm/infirm three main hypotheses: (1) field populations living in historically-impacted environments are more tolerant to metal stress than populations from reference sites; (2) resistance differences are genetically-determined, ...

Increased Probability of Extinction Due to Decreased Genetic Effective Population Size: Experimental Populations of Clarkia Pulchella.

We established replicated experimental populations of the annual plant Clarkia pulchella to evaluate the existence of a causal relationship between loss of genetic variation and population survival probability. Two treatments differing in the relatedness of the founders, and thus in the genetic effective population size (Ne ), were maintained as isolated populations in a natural environment. Af...

Historically browsed jewelweed populations exhibit greater tolerance to deer herbivory than historically protected populations

1. Browsing by overabundant white-tailed deer (Odocoileus virginianus) has altered ecological relationships in forest communities across eastern North America. Recent but limited work suggests that deer browsing also selects for particular plant defensive traits. 2. We hypothesized that browsing by deer has imposed selection on defensive traits in an annual native wildflower, orange jewelweed (...

Food effects on life history traits and seasonal dynamics of Ceriodaphnia pulchella

1. This paper describes the effects of differences in food quantity and quality on selected life history traits of Ceriodaphnia pulchella. Animals were fed with four concentrations of two green algae, Scenedesmus obliquus and Chlamydomonas globosa, given separately as well as in a 1 : 1 mixture. 2. In most cases growth, reproduction and condition of the animals and consequently the rate of popu...

Environmental influence on the genetic basis of mosquito resistance to malaria parasites.

The genetic basis of a host's resistance to parasites has important epidemiological and evolutionary consequences. Understanding this genetic basis can be complicated by non-genetic factors, such as environmental quality, which may influence the expression of genetic resistance and profoundly alter patterns of disease and the host's response to selection. In particular, understanding the enviro...
