“…(2023) where they showed that drought‐tolerant species are associated with smaller ranges in European and North American trees and shrubs compared to cold‐ and wet‐adapted species independently from latitude. Indeed, ecological strategy differentiation in resource economics represents a key indicator for abiotic stress tolerance of woody plants of the Northern Hemisphere (Pavanetto et al., 2024; Puglielli, Laanisto, et al., 2023). Furthermore, the relationship observed between specific leaf area and range size (Figure 2) is in line with the findings by Sporbert et al.…”

“…This is because enhanced colonization and competitive ability, driven by higher acquisitive traits, reduce biotic niche constraints on species occurrence, thus promoting species to become widespread early‐successional/generalists (Fristoe et al., 2021; Morin & Chuine, 2006). Besides the effects of biotic niche filtering, recent studies focusing on European and Northern American woody plants have shown that cold‐versus‐drought tolerance positively explains species range size (Puglielli, Laanisto, et al., 2023), and that higher resource‐acquisitiveness (in terms of the leaf economic spectrum, seed mass, and wood density) is associated with cold/waterlogging‐tolerant species compared to drought‐tolerant ones (Martínez‐Vilalta et al., 2023; Pavanetto et al., 2024).…”

AimPlant functional traits are frequently proposed as influential factors in species distribution. However, there is a gap in assessing how plant resource‐economic traits relate to the size and shape of a species' geographical range, and to what extent these relationships are conserved over evolutionary history. Specifically, an acquisitive strategy (characterized by heightened metabolism, shorter lifespan and quicker generation turnover) may promote isotropic range formations, resulting in less elongated and larger ranges. Here, I tested this link using data from 98 native European tree species.LocationPalaearctic.Time periodPresent.Major taxa studiedTrees.MethodsI used chorological maps to quantify two independent range attributes: species' range area and elongation. I considered 28 functional traits linked to resource‐use strategy measured in above‐ and below‐ground organs. I used multi‐response phylogenetic mixed models to calculate the conservative trait correlation (CTC) and the phylogenetically independent correlation (IND) component of each functional trait with range area and elongation.ResultsRange area positively correlated with resource acquisitive strategies, while range elongation correlated with resource conservative strategies. This pattern was consistent across the examined traits but statistically significant in seven out of the 28 traits, including specific leaf area, specific root area and root mycorrhizal colonization. Traits related to leaf and root nutritional status exhibited the weakest relationships with range attributes. Significant correlations were more frequent in the IND component and often showed contrasting trends compared to CTC.Main conclusionsPlant resource‐use strategy emerges as a relevant factor to gain insights on what shapes species' geographical distribution, alongside more established drivers such as dispersal limitation and climatic tolerance. Trait‐range relationships are driven by processes leaving a weak phylogenetic signature. These processes may result from direct selection, where functional traits impact range attributes, or indirect effects, such as the co‐variation of ranges and traits with environmental niche optima.

“…Using independent trait dimensions can in fact improve the interpretation of plant strategies (Laughlin, 2014). Including intraspecific trait variability (ITV, including ontogenesis) in this research agenda remains a priority since ITV can alter empirically determined trait trade‐offs (Fajardo et al., 2022; Kuppler et al., 2020; Niinemets, 2015; Puglielli, Cuevas Román, et al., 2017; Puglielli, Laanisto, et al., 2023; Zhou et al., 2022) and therefore trait dimensions, ultimately modifying trait–tolerance relationships. However, the current shortage of large‐scale ITV data (Chelli et al., 2019; Kattge et al., 2020) hinders filling this gap.…”

“…The trait‐based approach has been dominating the understanding of species' resistance to abiotic stressors (e.g., Hallik et al., 2009; Puglielli, Laanisto, et al., 2021, 2023; Sack, 2004; Stahl et al., 2013), defined here as a species' ability to tolerate adverse abiotic conditions in its natural environment (ecological tolerance, sensu Niinemets & Valladares, 2006, 2008). Most previous research has followed the hypothesis that adaptations to tolerate a given stress prevent species from simultaneously enduring other stresses.…”

AimTrade‐offs among tolerances to different abiotic stressors limit polytolerance in woody plants. However, the general trait syndromes that underlie large‐scale tolerance patterns of woody plants remain controversial. Here, we tested if the leading trait dimensions that define the global spectrum of plant form and function capture the underlying trait trade‐offs limiting woody plant polytolerance.LocationNorthern Hemisphere.Time PeriodPresent.Major Taxa StudiedWoody plants.MethodsWe used a dataset of 779 species to link the trait dimensions defining the global spectrum of plant form and function with two dimensions summarizing tolerance syndromes to drought, shade, cold and waterlogging. Stress tolerance dimensions were a trade‐off between drought and cold/waterlogging tolerance strategies, and a shade tolerance spectrum. Relationships among trait and stress tolerance dimensions were evaluated using general additive models separately for deciduous and evergreen angiosperms, and evergreen gymnosperms.ResultsDrought‐tolerant angiosperms showed greater specific stem density (SSD) and seed mass (SM), and lower specific leaf area (SLA) and leaf nitrogen content per mass (LN), compared to the cold/waterlogging‐tolerant species. Shade‐tolerant angiosperms displayed greater SSD and SM and lower SLA and LN compared to intolerant angiosperms. Highly contrasting trait adaptations also distinguished drought‐ (greater SSD, SM and lower SLA, LN) from shade‐tolerant evergreen gymnosperms.Main ConclusionsThe ‘SSD–SM’ and the ‘SLA–LN’ dimensions mainly distinguish cold or drought‐tolerant woody angiosperms and shade‐ or drought‐tolerant gymnosperms. Our results also support a conservative trait strategy for shade‐tolerant compared to shade‐intolerant species, with some differences between plant functional types probably due to contrasting leaf lifespans. Overall, our findings identify some leading functional constraints on polytolerance in woody plants and provide a framework to integrate additional trait dimensions to fully elucidate such constraints.

“…These alterations are represented by an abiotic stress gradient (Rosli et al, 2018). Abiotic stress gradient is understood as the factors that exert fundamental restrictions on the distribution, form, and function of sessile soil organisms (Puglielli et al, 2023). It also consists of all those foreign elements of the soil system or the existence of an unusual level that generates a harmful effect on soil organisms and their consumers (Egea et al, 2022).…”

The attributes of nematodes are presented as valuable tools for determining the quality of soil, especially that of mining companies. The aim of this study was to evaluate the behavior of nematodes against a stress gradient in a rainy season and a dry season in soils influenced by mining. Thus, field sampling was carried out over 100 m2 in triplicate for four types of soils classified according to their uses (pasture, maize cultivation, fig cultivation, and eucalyptus cultivation), and these areas were located on the periphery (500 to 1500 m) of the Ollachea mining community of Puno in Peru; subsequently, the samples were processed in the laboratory to determine edaphic, agrochemical, heavy metal, and microbiological parameters and identify the nematodes. The abiotic stress gradient was determined by a principal component analysis; and through a canonical correlation analysis, the relationships between the abiotic stress gradient and the nematodes were determined. Canonical correlation analysis showed that there were significant correlations: in the rainy season, Helicotylenchus and vanadium (r = 0.99), Globodera and titanium (r = 0.97), and Tylenchus and lead (r = 0.96); in the dry season: Meloidogyne and vanadium (r = 0.99), and Hemicycliophora and lead (r = 0.91). In conclusion, the abiotic stress gradient had a high correlation with bacterivorous, fungivorous, and phytoparasitic nematodes and a low correlation with omnivorous and predatory nematodes, showing the bioindicator capacity of nematodes in relation to stress parameters that impact soil quality.
