“…In general, we found low RDPI values and red oaks possess higher RDPI values than white oaks although the white oaks have a wider distribution in the study area; and at the leaf habit category, deciduous oak species possess higher RDPI values. Several studies have shown low plasticity across populations in other species ( Scholz et al 2014 ; Salazar et al 2019 ) or in species with no variation along an aridity gradient (e.g. Q. petraea ) in some vessel traits, suggesting that other anatomical features (e.g.…”

Oaks (Quercus L.) are a dominant woody plant genus in the northern hemisphere, which occupy a wide range of habitats and are ecologically diverse. We analyzed the wood anatomical traits, the variables derived, and the relative hydraulic conductivity of 21 oak species to identify their performance according to abiotic factors, leaf phenological patterns, and phylogenetic restrictions by analyzing the interspecific variation along an environmental gradient. First, we determine the causes of anatomical trait variation in the oaks, analyzing the functional trade-offs related to distribution along the environmental gradient. We measure the phenotypic plasticity of the anatomical traits to determine the role of environment and geographic distance in the range of phenotypic plasticity. Second, we examined if oaks co-occurred along the environmental gradient. Then we analyzed if wood anatomical traits reflect differences among their phylogenetic section, leaf habit, and a phylogenetic section/leaf habit category. Last, we tested the phylogenetic signal. Our results showed that vessel diameter, vessel frequency, wood density, and relative hydraulic conductivity are the main axes of trait variation in the species analyzed among leaf habit categories. The aridity index and seasonal precipitation drive the variation in the analyzed traits. Higher environmental distance resulted in a higher relative distance plasticity index among traits. Co-occurrence of oak species with different leaf habits and phylogenetic trajectories may promote complementary resource acquisition. The phylogenetic signal in the oak species studied was low, which implies labile wood traits.

“…Previous studies conducted on adult trees or seedlings of other Prosopis species inhabiting hyper arid deserts, such as P. caldenia, P. glandulosa, P. flexuosa and P. pallida (Ansley et al 2007, Guevara et al 2010, de Villalobos & Peláez 2015, Salazar et al 2019) have revealed a significant capacity for phenotypic adjustment through plastic responses of biomass allocation in response to water availability in mesquites. The results here presented suggest that besides phenotypic plasticity, potentially genetically determined functional differences among populations may be very important for survival during the very crucial stages of germination and seedling emergence, perhaps before plastic responses can come into play.…”

Background: Seedling establishment depends on the quality of the seeds and environmental conditions. Differential biomass allocation in emergent seedlings probably constitutes a relevant adaptive response of populations along environmental gradients. Questions: Are there differences in seed mass and biomass allocation in seedlings among Prosopis laevigatapopulations? Is this variation correlated with environmental variables? Studied species: Prosopis laevigata (Humb. & Bonpl. ex Willd.) M.C.Johnst (Fabaceae). Study site and dates: Thirteen localities along the distribution of P. laevigata in México. From 2016 to 2020. Methods: Seeds were collected from four or five mother trees per locality. Seed mass (SM) was obtained in ten seeds per mother and six functional traits indicative of biomass allocation were measured in the seedlings after 10 days of germination. Population mean values were obtained for the six traits plus SM and subjected to a principal component analysis (PCA). Population scores on the first two axis of the PCA were regressed against environmental variables from the collection localities using a stepwise regression model. Results: Populations displayed functional variation congruent with alternative biomass allocation strategies. The conservative strategy was characterized by larger seeds and seedlings with denser tissues and a higher investment in root biomass, while the opposite characterized the acquisitive strategy. Actual evapotranspiration in May, isothermality and soil water content in February were environmental variables that significantly predicted population scores on the first two axes of the PCA. Conclusion: Water availability gradients influence seed mass and seedling biomass allocation variation among P. laevigata populations.

“…Moreover, Liang et al. show that dove trees at high latitudes tend to have smaller twigs, and they use more resources for stems and leaves but less for flowers, indicating that dove trees adjust their growth and the distribution of twig biomass in response to environmental changes along a latitudinal gradient ( Salazar et al., 2019 ; Ma et al., 2021 ).…”
