Selecting cork oak and holm oak trees for stable tolerance to combined drought and Phytophthora cinnamomi stressNARA Subscribed
Using trees tolerant to drought and Phytophthora cinnamomi ( Pc ) infection is the most promising approach to restore Quercus suber and Q. ilex forests under decline. Breeding programs require heritability estimates for tolerance to combined stress. Moreover, the genetic variation underlying genotype-by-environment ( G × E ) interactions in oak tolerance to combined stress has not been explored. We evaluated life expectancy of...
Insights into chestnut (Castanea spp.) graft incompatibility through the monitoring of chemical and physiological parametersNARA Subscribed
Main conclusion Incompatible chestnut grafts exhibited a notably reduced stomatal conductance, mirroring the trend observed for leaf chlorophyll content. Woody tissues at the graft interface of these combinations showed a significantly higher total phenolic content, especially in the internal layers. Abstract In recent years, significant efforts have been made to study the mechanisms of graft incompatibility in horticultural s...
Geography and ecology shape the phylogenetic composition of Amazonian tree communitiesNARA Subscribed
Aim Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types. Location Amazonia. Taxon A...
The chestnut gall wasp Dryocosmus kuriphilus is a major insect pest affecting chestnut trees worldwide. Medium and long-term control of this pest can be improved by using resistant or less susceptible cultivars and hybrid clones. In addition, little is known about the local patterns of dispersal of the pest. We obtained data from trees of 3 chestnut species and 27 hybrid clones in a field trial in NW Spain with the aim of eval...
Geographic patterns of tree dispersal modes in Amazonia and their ecological correlatesNARA Subscribed
Aim To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser‐availability hypothesis) and/or the availability of resources for constructing zoocho...
