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
molitor, sex-specific patterns of actuarial senescence are not expected to evolve in this species. Accordingly, males and females showed similar patterns of survival with age in populations with balanced sex-ratio. Our results may further indirectly suggest that divergent actuarial senescence between ...
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 ...
Third, our results inform the dynamics of speciation, showing that components of RI can evolve in a heterogeneous (across RI components) and non-uniform manner. Perhaps the most famous example of an expected non-linearity in speciation is the snowball effect for the evolution of intrinsic hybrid ...
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,...
Census (N) and effective population size (Ne) are key parameters that can affect adaptation, 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...
The small differences in CaM between 12 and 28°C temperature were partially explained by cardiac remodeling where individuals acclimatized to 12°C had larger hearts than individuals acclimatized to 28°C. Correlation among physiological traits was dependent on acclimation temperature. For example, ...
(Table1, and Fig.3B). Within each of the H-S, H-N, V-E and V-W subareas individuals had a high likelihood of being assigned to a single cluster, which was shared across populations within the subarea. For example, the fish captured from the four caves in the H-S subarea had ...
As the tetraploid taxa should have originated from a small number of individuals, it is plausible that they lost the S-allele polymorphism responsible for the self-incom- patibility system. Once lost, the self-incompatibility system might have been difficult to recover in these populations ...
First, tradeoffs can be explained by the existence of sexual conflicts that lead to the antagonistic coevolution between individuals of different sexes. For example, in male-hermaphrodite reproduction systems, increased male mating success may be associated with hermaphrodites becoming mor...
