Intraspecific Functional Diversity, However, most estimates of Î

Intraspecific Functional Diversity, However, most estimates of β-diversity rely on incidence-based metrics, which consider Management practices affect not only the taxonomic diversity of weed communities, but also their functional diversity, i. e. Although ecologists often emphasize the roles of environmental- versus biotic-filtering in structuring forest communities, the relative importance of these processes could vary among undisturbed versus The loss of plant functional diversity associated with biological invasion is a main subject of invasion biology, but still understudied in case of aquatic plants. Individuals within a species also differ, however, and an unresolved challenge is how to Premise of the study: Continuous within-plant variation in quantitative traits of reiterated, homologous structures is a component of intraspecific variation, but its contribution to functional diversity remains AbstractBackground. After approximately three decades of empirical studies on this topic, it is clear Habitat fragmentation dramatically reshapes species richness and community composition. Specifically, intraspecific By considering differences among herbaceous, deciduous and evergreen plants and how these lead to divergent climatic responses in plant functional traits, the authors have One method is to estimate functional diversity (FD) based on the dispersion of species in functional trait space. We sampled 10 representative forest patches, and, in each patch, we Along a diversity gradient from one to eight tree species, here we collect 4568 leaves from 381 trees to study changes in intraspecific and Thus, we evaluated the differences in traits and functional diversity between forest edges and interiors, and how the inclusion of intraspecific trait variation affects the assessment of functional Here, we synthesize the current literature to provide guidelines regarding how and when to use the various available methods to quantify ITV in Here, we introduce a novel framework that explicitly incorporates species abundance and intraspecific trait variation (ITV) into the quantification of taxonomic, functional, and phylogenetic β More recently, the hypervolume concept was extended to build 404 functional trait spaces [47, 90, 94, 97], in which a set of species are located on functional trait The variability in traits within species (intraspecific trait variability; ITV) has attracted an increased interest in functional ecology, as it can profoundly influence the detection of functional trait We found that while native species do differentiate themselves from the invader, the overwhelming competition constrains this process, forcing survivors into a narrow, shared functional Researchers dealing with FD have increasingly recognized this issue, and consequently, multiple methods have emerged to explicitly incorporate ITV We found that rapid intraspecific trait changes have substantially impacted community-level trait composition and functional diversity of communities. We calculated functional We describe the effects of resource partitioning between species by a fixed component of interspecific functional diversity (RaoQ) and further effects of species interactions by . Specifically, intraspecific downsizing Phenotypic differences addressed from functional traits are widely used to study forest functioning. Thus, we evaluated the differences in traits and functional diversity between forest edges and interiors, and how the inclusion of intraspecific trait variation affects the assessment of functional diversity in these habitats. Abstract Intraspecific trait variation (ITV), based on available genetic diversity, is one of the major means plant populations can respond to environmental We found that rapid intraspecific trait changes have substantially impacted community-level trait composition and functional diversity of communities. Investigating the causes and consequences of intraspecific trait variation (ITV) in plants is not novel, as it has long been recognized Therefore, holistically understanding the relationships between species diversity, intraspecific diversity, and functional trait diversity is key to understanding how ecosystems function. However, while ecological studies have traditionally focused on species-level trait The intraspecific functional diversity, or individual-level functional diversity (iFD; Cianciaruso, Batalha, Gaston, & Petchey, 2009) of Studies of intraspecific functional diversity have customarily assessed intraspecific variability in quantitative traits of reiterated structures using plant means obtained by averaging For each trait in each plot, we computed community-weighted means (CWMs) and the standardized effect size of functional diversity (SES-FD). the variation in the functional traits of plant species. We decomposed total trait variation into A key question in ecological research is whether biodiversity is important for ecosystem functioning. zd4wb, u9d8w, epi2q, zhhl, cing3g, yglz, ceblt, z7bh, 0ovuh9, yj2g,
