Abstract The increasing disturbances in monocultures around the world are testimony to their instability under global change. Many studies have claimed that temporal stability of productivity increases with species richness, although ecological fundamentals mainly been investigated through diversity experiments. To adequately manage forest ecosystems, it is necessary a comprehensive understanding effect mixing on and way which influenced by climate conditions across large geographical areas....
Aim of study: The aim this paper is to compare differences in growth per hectare species pure and mixed stands as they result from different definitions proportions.Area Study: We used the data Spanish National Forest Inventory for Scots pine beech mixtures province Navarra Pyrenean oak Central mountain range North Iberic range.Material Methods: Growth models were parameterized with related its proportion dependent variable, dominant height, quadratic mean diameter density, independent...
Model-based inference is an alternative to probability-based for small areas or remote which probability sampling difficult. mean square error estimators incorporate three components: prediction covariance, residual variance, and covariance. The latter two components are often considered negligible, particularly large areas, but no thresholds that justify ignoring them have been reported. objectives of the study were threefold: (i) compare analytical bootstrap model parameter covariances as...
Accurate estimations on forest above-ground biomass (AGB) are essential for improving our ability to simulate vegetation response climate and assess the future role of forests as carbon sinks. In this context, Dynamic Global Vegetation Models (DGVMs) most important rapidly evolving tool estimate dynamics its potential trajectories in a warmer at regional global scales. However, DGVMs remain rather unprecise their estimation components due lack representation growth processes within model....
Aim of study: To present the evolution current multi-objective Spanish National Forest Inventory (SNFI) through assessment different key indicators on challenging areas forestry sector.Area Using information from Second, Third and Fourth SNFI, this work provides case studies in Navarra, La Rioja, Galicia Balearic Island regions at national scale.Material methods: These an estimation reference values for dead wood by forest types, diameter-age modeling Populus alba nigra riparian forest,...
In this paper we present a review of forest models developed in Spain recent years for both timber and non production dynamics (regeneration, mortality,..). Models are whole stand, size (diameter) class individual-tree. The to date have been using data from permanent plots, experimental sites the National Forest Inventory. show different sub-models so far friendly use software. Main perspectives modelling presented.
Scots pine (Pinus sylvestris L.) and European beech (Fagus sylvatica dominate many of the forest stands. Also, mixtures more or less occur over all countries, but have been scarcely investigated. The area occupied by each species is high relevance, especially for growth evaluation comparison different in mixed monospecific Thus, we studied methods to describe proportions their definition as proportion area. 25 triplets consisting stands were established across Europe ranging from Lithuania...
The abundance of stems in crowded populations and the subsequent self-thinning is a key issue forest stand dynamics. However, mechanisms that control are challenging to model. Although some attempts include climate structural traits like specific gravity (SG) promising, they remain confined North American species. In this study we aimed disentangle how SG along with two major abiotic stress tolerances, i.e. shade drought tolerance, contribute maximum density across climatic gradient Europe,...
Trees often show better growth in mixed as opposed to monospecific neighborhoods consequence of competition reduction and facilitation between species. However, it can be challenging discern the effect these factors they occur simultaneously, so are jointly refereed complementarity. By using tree models based on potential reduced by a modifier including species mixing effects both components (potential modifier), we aim verify that is modified admixture, which may provide further information...
