Behavioural syndromes are attracting the attention of evolutionary biologists because they mean that different behaviours might not be free to evolve independently of one another. In a landmark study, Huntingford (1976) showed that individual stickleback which were bold toward predators were also ...
Building upon a non-standard understanding of evolutionary process focusing on variation and persistence, I will argue that communities and ecosystems can evolve by natural selection as emergent individuals. Evolutionary biology has relied ever increasingly on the modeling of population dynamics. Most have...
Perhaps most importantly, studies of genomic differentiation, which necessarily capture the consequences of total RI (along with other evolutionary processes and demographic factors), have rarely been integrated with experimental data to study how specific components of RI evolve as speciation unfolds (see...
drift, and dispersal. The census population sizeNrefers to the total number of individuals or cells and can influence random dispersal as more individuals or cells increase the chances of arriving at new locations. In turn, the effective population sizeNerepresents the number of individuals ...
Recombination is a central biological process with implications for many areas in the life sciences. Yet we are only beginning to appreciate variation in the recombination rate along the genome and among individuals, populations and species. Spurred by t
Genomic variation patterns near these candidate loci reveal that individuals living near thermal effluents have rapidly evolved from the standing genetic variation through small allele frequency changes at many loci in a pattern consistent with polygenic selection on the standing genetic variation.While the...
Initially such a spread will lead to the coexistence of both infected and uninfected individuals in the population. This prolonged coexistence allows time for several traits to evolve (either by selection on already existing variation or on arising mutations). Here, we have shown that the most ...
Global methylation level and its distribution pattern of the native field samples in three sequence contexts. (a) The global methylation level (calculated as number of methylated cytosines/total number of cytosine) of the cytosine in the three populations (x-axis, individuals of three populations,...
(VK33) to control for background effects. We found that embryos from F1 individuals in Ind/lab background were larger than those in Canton-S/lab background (Fig.S8b), suggesting that the Ind background had a dominant effect on embryo size. Theevestripes in Ind/lab background were ...
cerana mating frequency is not a labile trait that can rapidly evolve or adapt to current circumstances (Tarpy et al., 2015). Notably, however, in both populations, variation among individual queens was high, with some queens having more than twice the mating frequency as others in the same ...
