These feedbacks are amplified by increased flammability driven by climate change, the presence of non-native flammable plant species, and slowed regeneration due to herbivory or dispersal limitation. In simulated landscapes with topographic variation, gullies act as refugia for older vegetation, modifying successional trajectories. Previous studies in Aotearoa–New Zealand have shown that fire, seed and seedling predation, and herbivory can interact to drive warm-temperate forest landscapes toward states dominated by flammable, early-successional vegetation (fire traps). We build on those previous studies, using a spatially explicit state-and-transition model to evaluate how topography and climate affect succession rates and the risk that landscapes could become fire traps. We also used the model to evaluate whether and how interactions among topography, climate, non-native mammalian herbivores, and non-native plants influenced the rate of succession. Although increased fire frequency was sufficient to drive landscapes into fire traps, non-native mammals intensified these effects by slowing regeneration and prolonging the period that vegetation remained in a high flammability, early successional state. Invasion by flammable, fire-adapted non-native woody species was favoured by frequent fire, and their presence further amplified positive fire–vegetation interactions. Interactions between fire regime and landscape context, such as the nature of the surrounding landscape mosaic, can further intensify these feedback dynamics. Ecosystem changes that are driven and reinforced by positive feedback dynamics challenge restoration efforts. Minimising the risk of warm temperate rainforest landscapes tipping into fire traps will require managing them through vulnerable flammable early successional communities as quickly as possible by 1) suppressing fire during this period and 2) minimising the effects of stressors that impede regeneration.</p>","PeriodicalId":51026,"journal":{"name":"Ecography","volume":"2026 9","pages":""},"PeriodicalIF":5.3,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecog.08550","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148408830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diatoms are known as ubiquitous microalgae that disperse passively and whose community can endure changing environmental conditions. While their diversity is well documented, the mechanisms driving diatom community assembly across spatial scales remain unclear. Here, we quantified the influence of ecological drift, environmental selection, and dispersal following a null-modelling procedure based on morphology-based phylogenetic distance (βNTI) and compositional turnover (RC<sub>Bray</sub>) in diatom communities from 18 mountain mires across four Iberian national parks. We conducted the study using a hierarchical spatial design: local (within mire): < 1 km, landscape (within national park): 1.5–45 km, and regional (Iberian Peninsula): 200–800 km (between national parks). Our results reveal a spatial continuum in community organization, shifting from a predominance of homogenizing dispersal at local scales (explaining up to 55.6 ± 28.5% of community variation) to ecological drift (27.8 ± 24.7%) and heterogeneous selection (environmental filtering) (22.5 ± 10.0%) at landscape and regional scales.

We herein used data from nine pelagic species (five fish and four squid) sampled from the high seas area of the northwest Pacific during the summer season, when they migrate there to optimize foraging efficiency and growth, and evaluated their niche partitioning in terms of dietary specialization. We measured the bulk carbon and nitrogen stable isotopes and essential fatty acids of the nine species to estimate the isotopic and nutritional niche spaces, and employed Hutchinson's n-dimensional hypervolume framework to examine the degree of dietary specialization. Results revealed that pairwise overlap of isotopic niches was observed for all species, though some species occupied distinct isotopic niche spaces. In contrast, the nutritional niche space, estimated using essential fatty acids, was mostly separate for each species, coupled with small or zero overlap between paired species. Furthermore, the specialization index, estimated using either stable isotopes or essential fatty acids, was consistently large for the nine species, while nestedness was relatively low.

We found that increases in greenness were strongly and positively linked to nitrogen deposition and this pattern held across major ecosystem types. Nitrogen deposition also had a larger coefficient estimate and explained more variation in the spatial pattern of vegetation greening than the other drivers, suggesting the association of greening with nitrogen deposition may be even stronger than with climate and land-use change. Although EVI increased slightly slower inside PAs, protection status did not alter the relationship between nitrogen deposition and greening.

Models calibrated over spatially restricted extents are often prone to truncating species' niches, whereas broad-scale models typically rely on coarse datasets that overlook fine-scale habitat constraints. The spatially nested SDM (N-SDM) approach addresses this challenge by combining global- and regional-level models to couple large-scale drivers with detailed, high-resolution environmental data. Here, we present N-SDM 2.0, a reengineered and extended successor to the original N-SDM software – the first end-to-end high-performance computing platform for spatially nested species distribution modelling. The new version offers improved usability and modularity, along with an extended range of modelling features, while maintaining continuity for users of the previous release. New modelling features include additional nesting methods, background-point generation strategies, and cross-validation options. These developments are complemented by an improved workflow architecture, a refined settings system, streamlined data-preparation steps, and greater control over data usage across spatial levels as well as error handling. N-SDM 2.0 is designed for flexible integration into heterogeneous high-performance computing environments, supporting large-extent and high-resolution biodiversity forecasting across an extensive number of species and projection scenarios. Beyond pure technical advances, N-SDM 2.0 strengthens the conceptual foundation of spatially nested species distribution modelling, introducing new features that form an open and scalable framework for mapping species distributions and robustly projecting their responses to global environmental changes.</p>","PeriodicalId":51026,"journal":{"name":"Ecography","volume":"2026 9","pages":""},"PeriodicalIF":5.3,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecog.08547","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148862388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used a long-term restoration experiment conducted in a species-poor, historically intensively managed grassland (Massif-central, France) to evaluate the relationships between land-use intensity, TADs dynamics, and the recovery of grassland plant species richness. TADs were quantified annually from 2004 to 2021 based on four traits related to plant architecture and leaf carbon economy. We analysed the temporal variability of TADs using the skewness–kurtosis relationship (SKR), a framework that explicitly accounts for stochasticity while revealing the imprint of deterministic processes on community assembly. TADs dynamics were not random, but were constrained according to trait- and land-use-specific SKR patterns. The cessation of fertilisation shifted TADs for all traits, from peaked distributions under fertilised management to more uniform distributions under unfertilised conditions. In the unfertilised treatment, TADs were also more stable than expected by chance and converged toward maximal trait evenness. Maximisation in trait evenness occurred during the early years of the experiment and preceded the long-term recovery of plant species richness. By explicitly accounting for stochastic community dynamics, our study reveals how plant communities reassemble during ecological restoration of grasslands historically degraded by intensive management and identifies the maximisation of trait evenness as a predictive benchmark linking early community reorganisation to long-term biodiversity recovery.</p>","PeriodicalId":51026,"journal":{"name":"Ecography","volume":"2026 9","pages":""},"PeriodicalIF":5.3,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecog.08309","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148364945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
