A slow-fast trait continuum at the whole community level in relation to land-use intensification

Abstract Organismal functional strategies form a continuum from slow- to fast-growing organisms, in response common drivers such as resource availability and disturbance. However, whether there is synchronisation of these at the entire community level unclear. Here, we combine trait data for >2800 above- belowground taxa 14 trophic guilds spanning disturbance gradient German grasslands. The results indicate that most consistently respond through both direct trophically mediated effects, resulting ‘slow-fast’ axis community. Using 15 indicators carbon nutrient fluxes, biomass production decomposition, also show fast communities are associated with faster rates ecosystem functioning. These findings demonstrate ‘slow’ ‘fast’ can be manifested whole communities, opening new avenues ecosystem-level classification.

A comprehensive framework for vegetation succession

Abstract Succession is defined as a directional change in species populations, the community, and ecosystem at site following disturbance. fundamental concept ecology it links different disciplines. An improved understanding of succession urgently needed Anthropocene to predict widespread effects global on recovery, but comprehensive successional framework (CSF) lacking. A CSF synthesize results, draw generalizations, advance theory, make decisions for restoration. We first show that an integral part socio‐ecological system dynamics driven by social ecological factors operating spatial scales, ranging from patch globe. then present local scale (patch landscape) which takes place explain underlying processes mechanisms scale. The reflects increasingly broader perspective includes recent theoretical advances not only focusing replacement also development, considering system, taking effect past current land use, landscape context, biotic interactions, feedback loops into account. discuss how can be used integrate studies, its implications

Coordination of leaf, root, and seed traits shows the importance of whole plant economics in two semiarid grasslands

New Phytologist, Год журнала: 2024, Номер 241(6), С. 2410 - 2422

Summary Uncertainty persists within trait‐based ecology, partly because few studies assess multiple axes of functional variation and their effect on plant performance. For 55 species from two semiarid grasslands, we quantified: (1) covariation between economic traits leaves absorptive roots, (2) among traits, height, leaf size, seed mass, (3) relationships these species' abundance. Pairs analogous root were at least weakly positively correlated (e.g. specific area (SLA) length (SRL)). Two pairs such N content DMC moderately ( r > 0.5) whether grouped by site, taxonomic group growth form, or life history. Root diameter was with mass for all groups except annuals monocots. Species higher dry matter (LDMC) tended to be more abundant = 0.63). Annuals larger seeds 0.69). Compared global‐scale syntheses many observations mesic ecosystems, observed stronger correlations weaker SLA N, SRL N. In persistence may require coordination above‐ belowground dense tissues facilitate dominance.

Intraspecific variability of leaf form and function across habitat types

Ecology Letters, Год журнала: 2024, Номер 27(3)

Опубликована: Март 1, 2024

Abstract Trait‐based ecology has already revealed main independent axes of trait variation defining spaces that summarize plant adaptive strategies, but often ignoring intraspecific variability (ITV). By using empirical ITV‐level data for two dimensions leaf form and function 167 species across five habitat types (coastal dunes, forests, grasslands, heathlands, wetlands) in the Italian peninsula, we found ITV: (i) rotated define space; (ii) increased variance explained by these (iii) affected functional structure target space. However, magnitude effects was rather small depended on type. Our results reinforce idea ITV is context‐dependent, calling careful extrapolations patterns traits spatial scales. Importantly, our study provides a framework can be used to start integrating into space analyses.
