Remote Spectral Detection of Canopy Functional Dimensions Varying Within and Across Forest TypesNARA Subscribed
Global trait axes reveal overarching dimensions of plant functional variation. However, how these dimensions are spatially organized within and across forest types remains unclear. We combined drone‐based full‐range imaging spectroscopy with crown‐level measurements of 16 physiological, morphological and biochemical traits across temperate, subtropical and tropical forests in China to enable spatially‐explicit trait mapping. T...
Bridging Conservation Gaps: Evaluating Habitat Mapping Methods for Alpine River EcosystemsNARA Subscribed
Natural habitats are globally threatened and fragmented, posing challenges for dynamic ecosystems dependent on ecological processes and intact habitat networks. Our study, therefore, examines the implementation of the European Union’s Habitats Directive in safeguarding the habitat type “Alpine rivers with their ligneous vegetation with Myricaria germanica ”. Using Bavarian and Austrian mapping guidelines, alongside simple and...
Leaf microbiome assembly is linked to plant phylogenyNARA Subscribed
Background and aims The plant microbiome is considered as an extended part of the plant genome, and it provides key functions in regulating plant fitness, and stress tolerance. Plants and associated microbiomes have co-evolved over millennia, yet evidence for a strong influence of plant phylogeny on their microbiomes is largely lacking. Our aim was to assess relative contributions of soil microbial diversity, host phylogenetic...
Soil Protist Diversity and Biotic Interactions Shape Ecosystem Functions Under Climate ChangeNARA Subscribed
Soil protists significantly influence ecosystem multifunctionality (EMF) through their roles in microbial predation, parasitism, and organic matter decomposition. However, the multifaceted contributions of protist diversity, along with its interactions with other microbial groups and plant diversity, to EMF—especially under climate‐induced stresses such as drought—remain poorly understood. To address this knowledge gap, we con...
Diversity in Resource Use Strategies Promotes Productivity in Young Planted Tree Species MixturesNARA Subscribed
Mixed‐species forestry is a promising approach to enhance productivity, increase carbon sequestration, and mitigate climate change. Diverse forests, composed of species with varying structures and functional trait profiles, may have higher functional and structural diversity, which are attributes relevant to a number of mechanisms that can influence productivity. However, it remains unclear whether the context‐dependent roles...
Spectral biology across scales in changing environmentsNARA Subscribed
Understanding ecosystem processes on our rapidly changing planet requires integration across spatial, temporal, and biological scales. We propose that spectral biology, using tools that enable near‐ to far‐range sensing by capturing the interaction of energy with matter across domains of the electromagnetic spectrum, will increasingly enable ecological insights across scales from cells to continents. Here, we focus on advances...
Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
Tree diversity shapes the spectral signature of light transmittance in developing forestsNARA Subscribed
Greater tree diversity often increases forest productivity by increasing the fraction of light captured and the effectiveness of light use at the community scale. However, light may shape forest function not only as a source of energy or a cause of stress but also as a context cue: Plant photoreceptors can detect specific wavelengths of light, and plants use this information to assess their neighborhoods and adjust their patte...
Dominance and rarity in tree communities across the globe: Patterns, predictors and threatsNARA Subscribed
Aim Ecological and anthropogenic factors shift the abundances of dominant and rare tree species within local forest communities, thus affecting species composition and ecosystem functioning. To inform forest and conservation management it is important to understand the drivers of dominance and rarity in local tree communities. We answer the following research questions: (1) What are the patterns of dominance and rarity in tree...
No general support for functional diversity enhancing resilience across terrestrial plant communitiesNARA Subscribed
Aim Understanding the mechanisms promoting resilience in plant communities is crucial in times of increasing disturbance and global environmental change. Here, we present the first meta‐analysis evaluating the relationship between functional diversity and resilience of plant communities. Specifically, we tested whether the resilience of plant communities is positively correlated with interspecific trait variation (following th...
Is our understanding of aquatic ecosystems sufficient to quantify ecologically driven climate feedbacks?NARA Subscribed
The Earth functions as an integrated system—its current habitability to complex life is an emergent property dependent on interactions among biological, chemical, and physical components. As global warming affects ecosystem structure and function, so too will the biosphere affect climate by altering atmospheric gas composition and planetary albedo. Constraining these ecosystem‐climate feedbacks is essential to accurately predi...
Aim To determine the relationships between the functional trait composition of forest communities and environmental gradients across scales and biomes and the role of species relative abundances in these relationships. Location Global. Time period Recent. Major taxa studied Trees. Methods We integrated species abundance records from worldwide forest inventories and associated functional traits (wood density, specific leaf area...
The geographic range size and vulnerability to extinction of angiosperm epiphytes in the Atlantic Forest of BrazilNARA Subscribed
Aim Angiosperm epiphytes have long been reported to have larger geographic ranges than terrestrial species, despite evidence of their outstanding diversity and endemism. This apparent contradiction calls for further investigation of epiphytes' poorly understood range size patterns. Here, we address the question of whether epiphytes have larger geographic ranges and different vulnerability to extinction than terrestrial species...
Herbaceous vegetation responses to experimental fire in savannas and forests depend on biome and climateNARA Subscribed
Fire–vegetation feedbacks potentially maintain global savanna and forest distributions. Accordingly, vegetation in savanna and forest ecosystems should have differential responses to fire, but fire response data for herbaceous vegetation have yet to be synthesized across biomes. Here, we examined herbaceous vegetation responses to experimental fire at 30 sites spanning four continents. Across a variety of metrics, herbaceous v...
The degree to which elevated CO 2 concentrations (e[CO 2 ]) increase the amount of carbon (C) assimilated by vegetation plays a key role in climate change. However, due to the short‐term nature of CO 2 enrichment experiments and the lack of reconciliation between different ecological scales, the effect of e[CO 2 ] on plant biomass stocks remains a major uncertainty in future climate projections. Here, we review the effect of e...
Projected impacts of climate and land use changes on the habitat of Atlantic Forest plants in BrazilNARA Subscribed
Aim To provide novel evidence on the average impact of climate and land use changes on habitat suitability for tropical plants and to test previous conclusions on the relative importance of these two drivers in shaping future availability of habitat for tropical plant species. Location Brazil’s Atlantic Forest domain. Time period Plant occurrences recorded between 1960 and 2014. Baseline climate from 1960 to 2000 and land use...
