We present cricketsim, an individual-based simulator of species and community dynamics that allows experimenters to manipulate genetic and evolutionary parameters as well as parameters affecting the simulated environment and its inhabitants. The simulator can model genotypic and phenotypic...

Recent research has identified genetic diversity in the ability of animals to manufacture and recognize leptin, a protein that regulated appetite and weight. This paper determines the economic value of using information on leptin genotype to select and manage beef cattle. Results reveal that the...

A prominent facet of recent changes in agriculture has been the advent of precision breeding techniques. Another has been an increase in the level of information inputs and outputs associated with agricultural production. This paper identifies ways in which these features may complement in...

The availability of very dense genetic maps is changing in a fundamental way the methods used to identify the genetic basis of both rare and common inherited traits. The ability to directly compare the genomes of two related individuals and quickly identify those regions that are inherited...

Scholars have long focused on socio-psychological attachment, elite discourse, and rational action to explain the nature and structure of ideologies. Recently genetic and neurobiological influences have also emerged as predictors of ideological preferences. So far however, there has been little...

Recent studies have shown that variation in political attitudes and participation can be attributed to both genes and the environment. This finding raises the question of why genes matter to participation, and by which pathways. Two hypotheses suggest that feelings of civic duty and sense of...
