Age and size at the first reproduction reproductive allocation of plants are linked to different life history strategies. Aleppo pine only reproduces through seed, and, as such, early female confers high fitness in its infertile highly fire-prone habitats along Mediterranean coast because expectancy is short. We investigated extent ecotypic differentiation examined relation between vegetative growth. In a common-garden experiment, threshold age seven differed significantly among provenances...
Summary The relevance of interspecific variation in the use plant water sources has been recognized drought‐prone environments. By contrast, characterization intraspecific differences uptake patterns remains elusive, although preferential access to particular soil layers may be an important adaptive response for species along aridity gradients. Stable isotopes were analysed and xylem samples 56 populations drought‐avoidant conifer Pinus halepensis grown a common garden test. We found that...
A plastic response towards enhanced reproduction is expected in stressful environments, but it assumed to trade off against vegetative growth and efficiency the use of available resources deployed [reproductive (RE)]. Evidence supporting this expectation scarce for plants, particularly long-lived species. Forest trees such as Mediterranean pines provide ideal models study adaptive value allocation vs. given their among-population differentiation traits remarkable capacity cope with dry...
Phenotypic plasticity is a relatively new name for very old issue in plant sciences: the ability of genotype to generate range different phenotypes, depending on environment. Contrasting with great deal published research works recognising plastic responses wide variety organisms, direct evidences adaptive role such are still scarce and evolutionary implications phenotypic under discussion. Different types plasticity, operating at levels within individuals or across generations have been...
PREMISE OF THE STUDY: Serotiny, the maintenance of ripe seeds in closed fruits or cones until fire causes dehiscence, is a key adaptive trait plants fire‐prone ecosystems, but knowledge phenotypic plasticity for cone retention woody extremely scarce. On basis published literature and our field observations, we hypothesized that increased aridity might decrease aerial seed bank as plastic response, not necessarily adaptive. METHODS: We used Pinus halepensis common garden replicated three...
Many ecologically important forest trees from dry areas have been insufficiently investigated for their ability to adapt the challenges posed by climate change, which hampers implementation of mitigation policies. We analyzed 14 common-garden experiments across Mediterranean studied widespread thermophilic conifer Pinus halepensis and involved 157 populations categorized into five ecotypes. Ecotype-specific tree height responses were applied projected change (2071-2100 ad), project potential...
A heteroblastic (or vegetative phase) change is an abrupt manifestation in the general development during ontogeny of plants. The Canary Island pine undergoes especially marked and delayed change, including both formation secondary needles on dwarf shoots onset preformed growth. To assess genetic environmental effects this species, we followed plants from 19 populations at a dry site wetter site. Comparing juvenile adult same individuals, had significantly lower rate water loss higher leaf...
Life histories in Mediterranean pines are well known to be closely related different fire and disturbance regimes. Variation these factors is also reflected reproductive strategies at the specific intraspecific level. Specifically, onset of reproduction a crucial stage for any organism because it has profound implications on fitness. In this paper we focused variation plasticity threshold size allocation two pines, assessed reproduction, when trade-offs between growth expected greater....
The Mediterranean stone pine, Pinus pinea L., seems to be well adapted the different climate zones of its distribution range that spans four thousand kilometres along Northern shore Sea. But recent molecular studies revealed it extremely genetically depauperate for a widespread tree. In this context, provenances trial should elucidate whether any differentiation in adaptative traits can identified between 34 accessions covering natural range. presence strong spatial autocorrelations...
Heartwood radius at breast height was studied in 31 sampling sites from natural stands of Canary Islands pine (Pinus canariensis Chr. Sm. ex DC) covering the range species. After withdrawal defective and nonheartwood samples, 1640 sound radial cores ranging age 30 to 265 years were analysed. Linearized models for prediction heartwood obtained using stepwise regression methods. The best fit attained including early growth variables (radius 25 or 50 inner rings), while stem inside bark whole...
A central question for understanding the evolutionary responses of plant species to rapidly changing environments is assessment their potential short-term (in one or a few generations) genetic change. In our study, we consider case Pinus pinaster Aiton (maritime pine), widespread Mediterranean tree, and (i) test, under different experimental conditions (growth chamber semi-natural), whether higher recruitment in wild from most successful mothers due better performance offspring; (ii)...
Research Highlights: We experimentally tested different seed sourcing strategies (local, predictive, climate-predictive, climate-adjusted, composite and admixture) under a climate change high emissions scenario using Scots pine multi-site provenance test. Background Objectives: There is an urgent need to conserve genetic resources support resilience of conifer species facing expected changes threats. Seed have been proposed maximize the future adaptation our forests. However, these proposals...
Abstract Premise Maternal effects have been demonstrated to affect offspring performance in many organisms, and plants, seeds are important mediators of these effects. Some woody plant species maintain long‐lasting canopy seed banks as an adaptation wildfires. Importantly, stored serotinous cones produced by the mother under varying ontogenetic physiological conditions. Methods We sampled bank a highly population Pinus pinaster test whether maternal age growth environmental conditions during...
Remote sensing is increasingly used in forest inventories. However, its application to assess genetic variation trees still rare, particularly conifers. Here we evaluate the potential of LiDAR and RGB imagery obtained through unmanned aerial vehicles (UAVs) as high-throughput phenotyping tools for characterization tree growth crown structure two representative Mediterranean pine species. To this end, investigated suitability these intraspecific differentiation a wide array morphometric...
