We studied the effects of tree species on leaf litter decomposition and forest floor dynamics in a common garden experiment 14 (Abies alba, Acer platanoides, pseudoplatanus, Betula pendula, Carpinus betulus, Fagus sylvatica, Larix decidua, Picea abies, Pinus nigra, sylvestris, Pseudotsuga menziesii, Quercus robur, rubra, Tilia cordata) southwestern Poland. used three simultaneous bag experiments to tease apart via chemistry vs. environment. Decomposition rates its plot origin were negatively...
1. There are conflicting reports concerning the adaptive features of tree populations originating from cold, high‐altitude environments. We hypothesize that such trees will possess be demonstrated in a common environment, as elevated rates net CO 2 exchange, needle nitrogen concentration and high proportional biomass allocation to roots. To test this hypothesis we measured seed properties 54 Norway spruce [ Picea abies (L.) Karst.] located along eight altitudinal transects (from c. 600...
Spectra of leaf traits in northern temperate forest canopies reflect major differences longevity between evergreen conifers and deciduous broadleaf angiosperms, as well plastic modifications caused by within-crown shading. We investigated (1) whether long-lived conifer leaves exhibit similar intra-canopy plasticity short-lived broadleaves, (2) global interspecific relationships photosynthesis, nitrogen, structure identified for sun adequately describe differentiated response to light...
Abstract Patterns and mechanisms of short‐term temperature acclimation long‐term climatic adaptation respiration among intraspecific populations are poorly understood, but both potentially important in constraining respiratory carbon flux to climate warming across large geographic scales, as well influencing the metabolic fitness populations. Herein we report on leaf dark 33‐year‐old trees jack pine ( Pinus banksiana Lamb.) grown three contrasting North American common gardens (0.9, 4.6, 7.9...
Plant functional traits may be altered as plants adapt to various environmental constraints. Cold, low fertility growing conditions are often associated with root adjustments increase acquisition of limiting nutrient resources, but they also result in construction roots reduced uptake potential higher tissue persistence. It is ultimately unclear whether produce fine different structure response decreasing temperatures and these changes represent a trade-off between function or We assessed...
We explored environmental and genetic factors affecting seasonal dynamics of starch soluble nonstructural carbohydrates in needle twig cohorts roots Scots pine (Pinus sylvestris L.) trees six populations originating between 49 degrees 60 N, grown under common garden conditions western Poland. Trees each population were sampled once or twice per month over a 3-year period from age 15 to 17 years. Based on similarity concentration patterns needles, two distinct groups identified; one comprised...
The resource strategy of seedlings is an important aspect for understanding the adaptation trees at this ontogenetic phase to abiotic changes. In study, we sought determine patterns response functional traits a shade-tolerant (A. platanoides) and shade-intolerant (Q. robur) species along natural environmental light gradients. We conducted trait-based analyses both individual community levels using direct (leaf area index, LAI; diffuse non-interceptance, DIFN) indirect (Ellenberg-indicator...
Abstract Aim Scots pine is one of the dominant tree species in forest ecosystems temperate and boreal zones Eurasia. Since Tertiary, it has persisted also Mediterranean region, forming relict populations. In this study, we investigate range‐wide genetic diversity pine, aiming to provide comprehensive information on phylogeography resources species. Location Europe Asia. Methods Thirteen paternally inherited chloroplast microsatellite (cp SSR ) loci were used structure 62 populations from...
Abstract Occupancy of cold habitats by evergreen species requires structural modification photosynthetic organs for stress resistance and longevity. Such modifications have been described at interspecific level, while intraspecific variation has underexplored. To identify anatomical traits that may be adaptive in environments, we studied variability needles Scots pine ( P inus sylvestris L.), a wide‐ranging tree, along 1,900 km temperate–boreal transect Europe. Needles from 20 sites...
Leaves developing in different irradiances undergo structural and functional acclimation, although the extent of trait plasticity is species specific. We tested hypothesis that irradiance-induced photosynthetic anatomical traits lower highly shade-tolerant than moderately species. Seedlings two evergreen conifers, Abies alba Mill. Picea abies Karst., deciduous angiosperm species, Fagus sylvatica L. Acer pseudoplatanus L., were grown deep shade (LL, 5% full irradiance) or solar irradiance...
Needles of evergreen conifers are not only photosynthetic organs, but they may also serve as storage sites for carbohydrates and nutrients. Since nitrogen is both a component photosynthetically active molecules nutrient stored in the needles mobilized shoot regrowth, we searched evidence trade-off between needle N capacity. Using sequential sampling, tracked seasonal patterns structure, (N mass) carbohydrate concentration, gas exchange all age classes (current-year, 1- 2-year-old) present on...
Physical and chemical defenses of seeds are essential for plant survival reproduction. By protecting their from herbivores other threats, plants can ensure that offspring have a better chance surviving growing into adult plants. Plant seed-size variation affect ability to allocate defense resources nutrients. Smaller tend contain fewer likely be more constrained in resource allocation or nutrient supply the germinating seedling than larger seeds. In this study, we hypothesized (1) trade-off...
Field‐grown trees of Alnus incana (L.) Moench, glutinosa Geartner and Betula pendula Roth displayed pronounced differences in responses light‐saturated net photosynthesis ( A sat ) to herbivory by the alder beetle Agelastica alni L., Galerucinae), a specialized insect which primarily defoliates alders. We found that photosynthetic rates grazed leaves increased following but not . Area‐ mass‐based declined linearly with increasing amount leaf perforation B. , as much 57%. By contrast...
In evergreen plants, old leaves may contribute photosynthate to initiation of shoot growth in the spring. They might also function as storage sites for carbohydrates and nitrogen (N). We hence hypothesized that whole-plant allocation N stems roots be lower than deciduous species. selected three species pairs consisting an a related species: Mahonia aquifolium (Pursh) Nutt. Berberis vulgaris L. (Berberidaceae), Prunus laurocerasus serotina Ehrh. (Rosaceae), Viburnum rhytidophyllum Hemsl....
The correlations of phenotypic traits with environmental drivers suggest that variability these is a result natural selection, especially if such trait are based on genetic variability. We hypothesized in situ structural needle Scots pine (Pinus sylvestris L) minimal winter temperature (Tmin) reported previously from temperate/boreal transect would be conserved when plants cultivated under common conditions. tested this hypothesis by analyzing needles two gardens located the temperate zone,...
