DNA methylation and histone acetylation: genotypic variations in hybrid poplars, impact of water deficit and relationships with productivity

• Several reports on annual plants have already shown the involvement of epigenetic modifiers such as DNA methylation in their adaptation to abiotic stresses.• Nevertheless, the genotypic variations of epigenetic modifiers, their possible correlations with morphological traits and the impact of water deficit have not been described for perennial plants.• Six genotypes of Populus...

Effects of stand density on ecosystem properties of subalpine forests in the southern Rocky Mountains, USA

• Mixed coniferous, subalpine forest communities in the Rocky Mountains are historically dense and have experienced infrequent, high-severity fire. However, many of these high-elevation stands are thinned for a number of perceived benefits.• We explored the effects of forest stand density on ecosystem properties in subalpine forests in Colorado, USA, 17–18 y after forests were...

Spatial distribution of lineages of oak powdery mildew fungi in France, using quick molecular detection methods

• Powdery mildew is a major fungal disease of oaks in Europe. Recent studies using internal transcribed spacer (ITS) sequences suggested the presence of four different lineages (putative species). The objective of the study was to investigate the spatial distribution of these lineages/species and, in particular, to test the hypothesis of a spatial differentiation, at various...

Analysis of spatial patterns of oak decline in cork oak woodlands in Mediterranean conditions

• Cork oak mortality is a recurrent problem in southwestern Portugal. Despite the perception of increasingly visible damage in oak woodlands on drought-prone sites, the role of the various environmental factors in their decline is not clear.• To describe the spatial patterns of cork oak (Quercus suber L.) mortality, a cork oak mortality index (MI) was determined for each...

Spatial and temporal variability of natural regeneration in a temperate old-growth forest

• The natural regeneration of shade-tolerant tree species is characterized by large spatial heterogeneity and temporal variability. The mechanisms producing those patterns are still poorly understood and the knowledge of long-term fluctuations in regeneration processes is very limited.• We used data from long-term study plots in an old-growth stand dominated by European beech and...

Microsatellites used to establish full pedigree in a half-sib trial and correlation between number of male strobili and paternal success

• Paternity was established in a field trial of Abies nordmanniana with open-pollinated (OP) offspring from a clonal seed orchard (CSO) comprising 23 clones.• The purposes were to: (1) investigate the violation of the assumption of true half-sibs in OP progeny trials; (2) assess the value of male strobili scorings to predict paternal contributions in CSOs; and (3) study the bias...
