Abstract Questions Does the non‐native evergreen Chinese windmill palm ( Trachycarpus fortunei ) affect native plant community and forest regeneration in deciduous forests? Are effects modulated by soil moisture? What are implications for management nature conservation? Location Broadleaved low‐elevation forests on southern slope of Alps across Swiss–Italian border region. Methods We compared herbaceous woody composition, species richness, Shannon diversity abundance at ten sites two moisture conditions (six mesic–moist four mesic–dry sites). Each site consisted three plots measuring 400 m 2 along a gradient T. presence, ranging from “dominant”, to “present but not dominant” “absent”. Results In with high densities , richness plants recruiting herb shrub layers were significantly reduced similar where is absent or dominant. However, these variables did differ between palm‐invaded uninvaded plots. The individuals invaded palms control either type. Conclusions expect detrimental consequences alluvial few more widespread non‐alluvial forests. recommend multifaceted management, including targeted eradication identified as hotspots diversity, accompanied hands‐off forests, recognizing ongoing inevitable “laurophyllisation”; biome shift toward mixed‐evergreen that may increase ecosystem climate resilience under climatic warming.

Could Tropical Cyclone Expansion Boost Migration of Temperate Trees to Boreal Forests?

Wiley Interdisciplinary Reviews Climate Change, Journal Year: 2025, Volume and Issue: 16(2)

Published: March 1, 2025

ABSTRACT The poleward expansion of tropical cyclones (TCs) inevitably triggers unprecedented ecological consequences for cool‐temperate and boreal forests, including shifts in species distribution, global carbon dynamics, or forest policies. However, our current understanding the impact TCs' into new regions is limited lacks attention by both, media research community, compared to on (sub‐) forests. Shifts TC activity are expected pose a considerable threat extensive areas globally under climate change. Nevertheless, we suggest that TCs should not only be perceived as destructive weather phenomena but also vehicle (i) facilitating migration temperate southern forests (ii) mitigating change ecosystems. Hence, it vital establish coherent long‐term large‐scale capture unique ongoing (and currently overlooked) processes induced expansion, which may lead complex transition dynamic.

The what, how, and why of trait‐based analyses in ecology

Functional diversity is increasingly used alongside taxonomic to describe populations and communities in ecology. Indeed, functional metrics allow researchers summarise complex occupancy patterns space and/or time across response various stressors.

However, as the methods increases, it often not directly clear which metric more readily appropriate for question. We studied ability different recover signals from processes linked common assembly mechanisms community ecology, such environmental filtering, competitive exclusion, equalising fitness, facilitation.

A bird in the hand: Global‐scale morphological trait datasets open new frontiers of ecology, evolution and ecosystem science

Ecology Letters, Journal Year: 2022, Volume and Issue: 25(3), P. 573 - 580

The recent prominence of functional traits in ecological analyses is based on the premise that measurable attributes an organism's phenotype can take us beyond simple lists species and closer to valid tests mechanisms processes (Cadotte et al., 2011). However, full potential trait-based ecology evolutionary biology ultimately constrained by incomplete coverage completeness, particularly case morphological (Etard 2020).

Intercomparison of global foliar trait maps reveals fundamental differences and limitations of upscaling approaches

EarthArXiv (California Digital Library), Journal Year: 2023, Volume and Issue: unknown

Foliar traits such as specific leaf area (SLA), nitrogen (N) and phosphorus (P) concentrations play an important role in plant economic strategies ecosystem functioning. Various global maps of these foliar have been generated using statistical upscaling approaches based on in-situ trait observations.Here, we intercompare upscaled at 0.5° spatial resolution (six for SLA, five N, three P), categorize the used to generate them, evaluate with estimates from a database vegetation plots (sPlotOpen). We disentangled contributions different functional types (PFTs) characterized differences between two metrics: community weighted mean (CWM) top-of-canopy (TWM).We found that SLA N differ drastically fall into groups are almost uncorrelated (for P only one group were available). The primary factor explaining is exclusive use PFT information combined remote sensing-derived land cover products while other mostly relied environmental predictors. impact TWM or CWM patterns was considerably smaller than including information. exhibit considerable similarities strongly driven by cover. not PFTs show lower level similarity tend be individual variables.Overall, better reproduce between-PFT distributions plot-level sPlotOpen data, performed similarly capturing within-PFT variation. Upscaled both moderately correlated grid-cell-level data (R = 0.2-0.6), overall higher correlations N.Our findings highlight importance explicitly accounting within-grid-cell variation, which has implications applications existing future efforts.

Functional trait variability supports the use of mean trait values and identifies resistance trade‐offs for marine macroalgae

Journal of Ecology, Journal Year: 2023, Volume and Issue: 111(9), P. 2049 - 2063

Published: July 21, 2023

Abstract Trait‐based ecology (TBE) has proven useful in the terrestrial realm and beyond for collapsing ecological complexity into traits that can be compared generalized across species scales. However, TBE marine macroalgae is still its infancy, motivating research to build foundation of macroalgal by leveraging lessons learned from other systems. Our objectives were evaluate utility mean trait values (MTVs) species, explore potential intraspecific variability, identify strategies clustering with similar testing bivariate relationships between traits. To accomplish this, we measured thallus toughness, a associated resistance herbivory, tensile strength, physical disturbance, eight tropical up seven sites where they found around Moorea, French Polynesia. We interspecific variation generally exceeded species. Furthermore, MTV within varied sites, suggesting future should focus on whether these are influenced site‐specific differences biotic abiotic drivers. Species grouped three clusters representing different strategies: defended against herbivores but not strong, strong neither. Intraspecific standardized major axis regressions revealed five exhibited significant or marginally positive two traits, syndromes Only one trade‐off, as indicated negative regression slope. Synthesis . results point key takeaways provide rapidly advance development future. First, our evidence supports use MTVs macroalgae. Second, identified spatial variability may indicate an ability respond shifting environmental Third, measuring even few powerful tool resist disturbances such herbivory removal wave action. hope novel findings motivate wider suite functions further develop trait‐based approaches
