AimThe build‐up of local species diversity requires completing the transition from allopatry to sympatry to local coexistence (syntopy). However, understanding processes than enable species arising in allopatry to become syntopic remains an unsolved challenge. Potential explanations include niche conservatism, niche divergence, and energy availability. To gauge their importance, we modelled the effects of species split age, the divergence in beta and alpha niches, specialisation, and resource availability to reveal factors driving the evolution of local species coexistence upon speciation.LocationGlobal.Time PeriodMiocene to the present.Major Taxa StudiedPasserine birds.MethodsWe collated a dataset of 206 passerine sister species pairs, each with their age of divergence; range sympatry; degree of syntopy (derived from 7,257,312 complete eBird checklists falling within the area of range overlap); beta niche divergence (habitats and environmental characteristics); alpha niche divergence (morphology, diet, and foraging stratum); species ecological specialisation (diet and foraging stratum); resource availability; and body mass. We used phylogeny‐informed models to infer which of these factors best explained local species coexistence upon speciation.ResultsThere was a major effect of niche conservatism as species with more similar beta niches (canopy height, vegetation greenness, moisture availability, and habitat affinities) exhibited higher degree of syntopy. Small species with similarly sized beaks and high specialisation on diet were also more likely to coexist locally. In contrast, the divergence or overlap in alpha niches (diet and foraging stratum) did not predict the degree of syntopy. Confirming previous studies, the degree of syntopy strongly increased with increasing range sympatry, while only weakly in older species pairs.Main ConclusionsThe evolution of secondary syntopy is driven by niche conservatism, ecological specialisation, and body mass‐related energy requirements. Consequently, the accumulation of local species richness is facilitated by both conservatism and differentiation along various ecological niche dimensions.

MotivationTiming, duration and severity of marine heatwaves are changing rapidly in response to anthropogenic climate change, thereby increasing the frequency of coral bleaching events. Mass coral bleaching events result from cumulative heat stress, which is commonly quantified through degree heating weeks (DHW). Here we introduce CoralBleachRisk, a daily‐resolution global dataset that characterises sea surface temperatures, heat stress anomalies and the timing, duration and magnitude of severe coral bleaching conditions from the recent past (1985) to the future (2100) under three contrasting Shared Socioeconomic Pathways. Our projections are downscaled to a 0.5° resolution (~50 km), bias‐corrected and validated using remotely sensed data of sea surface temperatures and a global dataset of historical coral bleaching events. An accompanying online software tool allows non‐specialist users to access aggregated metrics of coral bleaching risk and generate time series projections of coral vulnerability for Earth's coral reefs. Our dataset enables regional to global comparisons of future trends in severe coral bleaching risk.Main Types of Variables ContainedSea surface temperature (SST), SST anomaly, DHW, annual timing and duration of Bleaching Alerts.Spatial LocationGlobal.Time Period1985–2100.Major Taxa and Level of MeasurementCoral communities.Software FormatNetcdf (.nc).

Classifying populations as native or nonnative requires well-defined range boundaries for species. While many studies define native status according to large biogeographic realms, natural dispersal barriers often limit species distributions at regional or smaller spatial extents. As such, native/nonnative definitions are inherently scale-dependent and estimates of community invadedness thus depend on the spatial resolution at which native status is defined. For example, nonnative species can be introduced among realms, among regions within realms, and among ecological provinces within regions (hereafter, simply “provinces”). By explicitly considering the scale-dependency of native/nonnative status definitions, we can more effectively compare results across studies, more comprehensively evaluate the degree of invasion levels, and more objectively communicate the native status of a species.

We assess the role of spatial distance and depth difference in shaping beta diversity patterns across abyssal seascape regions. We measured the decrease of faunistic similarity across the northeast Pacific seafloor, to test whether species turnover rates differ between deep and shallow-abyssal biogeographical provinces and whether these patterns vary across functionally or taxonomically different biotic groups.

Subterranean biodiversity is increasingly threatened by multiple intertwined anthropogenic impacts, including habitat loss, pollution, overexploitation of resources, biological invasions and climate change. Worryingly, subterranean biodiversity is still poorly represented in conservation agendas, also due to persisting gaps in our knowledge of the organisms thriving in the often-secluded and difficult-to-access subterranean ecosystems. This is even more apparent for small-sized (body size < 1 mm) groundwater-dwelling metazoans, among which copepods (Crustacea: Copepoda) represent the dominant group in terms of both species richness and biomass.

Drought reduces plant growth and hastens the process of leaf senescence in autumn. Concurrently, increasing atmospheric CO2 concentrations likely amplifies photosynthetic activity while increasing plant water-use efficiency. However, how drought affects the date of leaf senescence (DLS) and whether elevated CO2 can alleviate this remain unknown. Here, we explore the effect of drought on DLS under recent climate change and explore the underlying mechanisms.

Here, we explore the effect of drought on DLS under recent climate change and explore the underlying mechanisms.","PeriodicalId":176,"journal":{"name":"Global Ecology and Biogeography","volume":"35 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142935357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasing aridity has driven widespread synchronous fire occurrence in recent decades across North America. The lack of historical (pre-1880) fire records limits our ability to understand long-term continental fire-climate dynamics. The goal of this study is to use tree-ring reconstructions to determine the relationships between spatiotemporal patterns in historical climate and widespread fire occurrence in North American forests, and whether they are stable through time. This information will address a major knowledge gap required to inform projections of future fire.

Despite unprecedented environmental change due to anthropogenic pressure, recent work has found increasing dissimilarity due to turnover but no overall trend in species diversity through time at the local scale. Functional diversity provides a potentially powerful alternative approach for understanding community composition by linking shifts in species identity to the characteristics that underpin ecosystem processes. Here we present the first multitaxa, multisystem analysis of functional diversity and composition through time.

AimIt has been hypothesised that niche breadth decreases with richness due to interactions, such as competition, forcing species to specialise. This hypothesis has been tested at the community‐level using species‐level niche breadth estimates. However, evidence for changes in niche‐breath among populations of the same species are scant. Our aim was to examine the niche breadth to richness relationship within species, which is crucial for understanding the role of interactions, as opposed to large‐scale climate, in altering realised niche breadth.LocationThe Pacific Ocean.Time Period1988–2015.Major Taxa StudiedFishes.MethodsWe focus on reef fishes along a large‐scale richness gradient not accompanied by marked environmental changes. Fishes were surveyed in four distinct habitats, which allow to estimate habitat‐breadth for each population. We calculated habitat‐breadth across multiple populations of 154 species, and tested how habitat‐breadth varied with richness. We further tested the effect of traits and trait‐distinctiveness on the richness‐sensitivity of habitat‐breadth.ResultsHabitat‐breadth varied with species traits, with larger species more commonly habitat generalists while schooling and planktivorous species more commonly habitat specialists. Importantly, habitat‐breadth was negatively correlated with richness for 109 out of the 154 species, and, across all species, the relationship was highly significant. We found some support that species with distinct traits displayed less sensitivity of habitat‐breadth to richness, but the relationship was dependent on the type of trait‐distinctiveness index used.ConclusionsThis is the first large‐scale evidence that population‐level habitat‐breadth changes with richness. Results suggest that the realised niche is population‐specific and that niche breadth is reduced in high‐diversity settings where more intense interactions, such as competition, are expected. This implies that populations, specifically in species rich areas, do not use their entire fundamental niche. Therefore, the ability to predict habitat preferences response to global changes based on current habitat associations, without accounting for species interactions, may be limited.
