[hal-01088134] Relaxing the Hypotheses of Symmetry and Time-Reversibility in Genome Evolutionary Models
2 décembre 2014
Various genome evolutionary models have been proposed these last decades to predict the evolution of a DNA sequence over time, essentially described using a mutation matrix. By essence, all of these models relate the evolution of DNA sequences to the computation of the successive powers of the (...)
[hal-01074594] Cadmium accumulation in six common plant species associated with soils containing high geogenic cadmium concentrations at Le Gurnigel, Swiss Jura Mountains
28 octobre 2014
The uptake of cadmium (Cd) was analyzed for six different perennial plant species growing in a wooded pasture of the Swiss Jura Mountains, where the soils are geogenically enriched in Cd (4.58 mg·kg− 1 on average (n = 36); maximal value: 16.3 mg·kg−1). The six selected plants — Hypericum maculatum (...)
