Soil microbial legacies and drought mediate diversity–invasibility relationships in non‐native communities

New Phytologist, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 9, 2025

High native species diversity generally suppresses non-native invasions, but many ecosystems are now characterized by assemblages that vary in diversity. How this affects subsequent invaders and its environmental dependence remain unclear. We conducted a plant-soil feedback experiment. In the conditioning phase, we created three levels (1, 2, or 4 species) using six to condition soil. responding planted these individually with soil inocula exposed them two watering treatments (well-watered vs drought). Under well-watered conditions, biomass increased generated different This pattern was mainly related arbuscular mycorrhizal fungal richness which However, under drought did not depend on Our results reveal crucial role of microbial legacies driving positive diversity-invasibility relationships communities stress can eliminate relationships. These findings provide an explanation for commonly observed co-occurrence multiple nature, predicting accelerating accumulation benign environment, stressed environment.

Arbuscular mycorrhizal fungi regulate the diversity–invasion resistance relationship by influencing the role of complementarity and selection effects

Published: Feb. 12, 2025

Summary Arbuscular mycorrhizal fungi (AMF) play a crucial role in influencing plant community dynamics, yet their impact on the relationship between diversity and resistance, especially resistance to invasion, remains largely unclear. We conducted an experiment using communities with varying species richness (one, three six species) subjected them invasion by Solidago canadensis AMF inoculation. measured comparing biomass of invaded uninvaded investigated effect inoculation diversity–resistance relationship. Our results indicate that higher displayed greater this was stronger presence than its absence. weakened positive complementarity effect–resistance (i.e. decreasing asynchrony) due AMF‐induced alterations composition, but shifted negative selection neutral negative‐to‐neutral sampling effect) enhanced dominant Mosla scabra . Furthermore, changes were positively correlated relative growth rate specific root surface area. These findings suggest alters mechanisms underlying relationships, implications for how respond disturbances such as invasion.

Intraspecific trait variation and whole‐plant economics spectrum drive the abundance distributions of woody plants in island communities

Journal of Ecology, Journal Year: 2025, Volume and Issue: unknown

Published: April 10, 2025

Abstract Understanding the coexistence of common and uncommon species is crucial for exploring community assembly processes facilitating biodiversity conservation across spatial temporal scales. This study extends Equilibrium Theory Island Biogeography (ETIB) to explore how island geographical variables shape whole‐plant economics spectrum, emphasizing relationship between intraspecific trait variation (ITV) abundance. We quantified ITV within plant communities on 10 land‐bridge islands investigated its with Using generalized linear mixed models (GLMMs), we examined effects (island area, isolation, distance forest edge) abundance patterns. With a rarefaction method, identified positive correlation ITV. Common were predominantly located at core positions community‐wide distribution, whereas more often positioned margins. edge, abundance, their interactions all significantly influenced smaller, isolated along edges displayed traits indicative slow‐growth resource‐conservative (stress‐tolerant) strategies, while larger, less in interiors exhibited consistent fast‐growth resource‐acquisitive strategies. Synthesis . Higher may enhance tolerance heterogeneous habitats, supporting persistence despite environmental variability. Conversely, lower smaller population sizes increase vulnerability extinction due habitat loss fragmentation. Extending ETIB include provides novel insights into geography shapes strategies dynamics, offering valuable fragmented landscapes.

Temporal and habitat-specific variations in drivers of aboveground biomass dynamics in a Chinese subtropical forest

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 15

Published: Jan. 21, 2025

Understanding the mechanisms governing biodiversity-biomass relationships across temporal and spatial scales is essential for elucidating how abiotic biotic factors influence ecosystem function in natural forests. However, simultaneous contributions of multiple (e.g., topography) structural diversity) to aboveground biomass dynamics (ΔAGB) over time habitat types remain inadequately understood. To address this gap, we evaluated changes a decade various habitats, disentangling relative influences topography multidimensional diversity on ΔAGB through datasets from forest inventories conducted between 2007 2017, along with phylogenetic relatedness, functional traits, environmental variables subtropical China. Our findings indicate that at community level experienced significant decline followed by an increase decade, predominantly driven low-valley habitat. In contrast, no statistically alterations were detected mid-hillside high-ridge habitats. Furthermore, determinants exhibited variation. During 2007-2012 period, was primarily influenced diversity, accounting 66.11% 21.35% importance, respectively. subsequent 2012-2017 emerged as key factors, explaining 48.46% 36.43% Additionally, observed drivers effects impacting variability different types. summary, our study underscores spatiotemporal dependence within ecosystems, thereby enhancing understanding complex biodiversity-ecosystem functioning relationships.

Fungi are crucial for terrestrial ecosystems, yet the role of fungal diversity in ecosystem functions remains unclear. We synthesize biodiversity and function (BEF) relationships, focusing on plant biomass production, carbon storage, decomposition, pathogen or parasite resistance.
