Indirect genetic effects of rhizobium symbiosis plasmid on legume-grass dynamics
… grass productivity, then these facilitative effects of clovers on grasses might be heighted when clovers are associated with higher quality rhizobium. To investigate how this plasmid variation might affect legume-grass dynamics, we inoculated experimental mesocosms of mixed clover and grass …

The development of a Canadian resiliency index for dairy calf disease traits
… of these diseases by estimating incidence rates, genetic parameters, genetic correlations with economically significant traits, and recording practices on Canadian dairy farms. Additionally, a genome-wide association study (GWAS) was conducted to identify genomic regions linked to calf disease …

Japanese courage: a genetic analysis of complex traits in medaka fish and humans
… characteristics relevant to its utility for the genetic mapping of complex traits, including: the panel's evolutionary relationship with other previously-established inbred medaka strains; the degree of homozygosity in the inbred lines; the rate of linkage disequilibrium decay across the panel; …

Nurture is Nature: The Molecular Basis of Caregiver Genotype Effects on Larval Growth and Caste Development in the Clonal Raider Ant
<p>The distinction between nature (genetics) and nurture (environment) is blurry, in part because the environment includes the genes of social partners. This is especially evident for parents and their offspring, where genes expressed in one partner profoundly influence the physiology and behavior …

Mechanisms Maintaining Additive Genetic Variance in Fitness in Red Squirrels
A trait must genetically correlate with fitness in order to evolve, however, theory suggests that strong directional selection should erode additive genetic variance (Va) in fitness and limit future evolutionary potential. Sexual antagonism and temporal fluctuations in selection are mechanisms that …
