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...
Understanding species’ nest site selection is essential for successful species conservation, because it allows to identify critical areas, allocate resources efficiently, and formulate effective measures. One indirect way to assess this for migratory birds is by examining breeding timing, considering that higher-quality habitats are occupied earlier, while controlling for extrinsic and intrinsic factors. However, how site- and...
Plants employ multiple strategies to adapt to their growth environment. Characterizing key dimensions in plant trait space is important for understanding functional diversity within ecosystems. Leaf and root functional traits have been studied in the context of resource economics, but whether they covary, and through which mechanisms, is still debated. We investigated this in subtropical forests by sampling root and leaf trait...
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...
Earthworms Enhance Global Soil Carbon Storage Through Microbial–Mineral StabilizationNARA Subscribed
Earthworms play a dual role in the global carbon cycle: they accelerate organic matter decomposition yet are often associated with greater soil organic carbon (SOC) storage. However, uncertainty regarding the mechanisms and magnitudes through which earthworms concurrently influence SOC mineralization and stabilization has limited the integration of soil fauna into carbon models. Here, we synthesize 696 paired observations from...
Widespread Higher Soil Respiration Rates at Nighttime Than Daytime Across Global Forest EcosystemsNARA Subscribed
Soil respiration ( R s ) is the second largest terrestrial carbon flux and therefore its temporal dynamics exert a significant influence on the soil carbon budget. While the seasonal and annual dynamics of R s and its temperature sensitivity have been well documented, the diel R s dynamics remain poorly understood. Earth system models (ESMs) typically assume a constant temperature response of R s over the diel cycle, thereby p...
The southern boreal forest has experienced a profound shift in growth pattern because of climate change. However, it remains underexplored whether climate variation has increased interannual tree growth variability and if this trend is reversible under climate warming. On the basis of a field investigation and dendrochronological analysis, we evaluated the temporal changes in interannual tree growth variability across a temper...
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...
Climate and Land‐Use Changes Predicted to Jointly Drive Soil Fungal Diversity Losses in One‐Third of North American Coniferous ForestsNARA Subscribed
Soil fungi underpin key ecosystem functions but face increasing threats from climate and land‐use changes, with their future impacts remaining unclear. This uncertainty is exacerbated by limited large‐scale data and the challenge of quantifying and comparing both factors at comparable spatial scales. By leveraging two continental‐scale sampling networks in North America and applying stacked species distribution models combined...
Changes in temperature and rainfall associated with altered climatic conditions are likely to significantly alter rates of soil organic matter decomposition. To determine how the combined effects of warming and drought impact the decomposition of fungal necromass, a large and fast‐cycling portion of the global soil organic carbon (C) pool, we incubated Hyaloscypha bicolor necromass under both ambient and altered conditions (+3...
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...
Elevated CO 2 and N Gradually Weaken the Influence of Diversity on Ecosystem StabilityNARA Subscribed
Biodiversity promotes ecosystem productivity and stability, positive impacts that often strengthen over time. But ongoing global changes such as rising atmospheric carbon dioxide (CO 2 ) levels and anthropogenic nitrogen (N) deposition may modulate the impact of biodiversity on ecosystem productivity and stability over time. Using a quarter‐century grassland biodiversity‐global change experiment we show that diversity increasi...
Integrating Microbial Community Data Into an Ecosystem‐Scale Model to Predict Litter Decomposition in the Face of Climate ChangeNARA Subscribed
Litter decomposition is an important ecosystem process and global carbon flux that has been shown to be controlled by climate, litter quality, and microbial communities. Process‐based ecosystem models are used to predict responses of litter decomposition to climate change. While these models represent climate and litter quality effects on litter decomposition, they have yet to integrate empirical microbial community data into...
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...
Modest Experimental Warming Reduces Species Diversity and Biomass of Arthropods in a Tibetan Alpine MeadowNARA Subscribed
Climate warming is expected to contribute to the decline of arthropod species diversity and biomass around the world. However, direct experimental evidence is lacking. Here, we report on a field experiment documenting arthropod species diversity and biomass responses to passive simulated warming for six consecutive years in an alpine meadow on the Tibetan Plateau. The field warming experiment consisted of six large open‐top ch...
