Anthropogenic disturbance expands the climatic limits of annual plant dominance

Niv DeMalach, Roberto Salguero-Gomez, Oded Hollander, Jane Lucas et autres

Disturbance regimes and nutrient inputs are changing worldwide, with consequences for the structure and functioning of plant communities. Classical life-history theory predicts that disturbance should shift communities from long-lived perennials toward short-lived annuals, and that nutrient enrichment may amplify this shift. However, …

Effects of simulated nitrogen deposition on soil phosphorus availability and element composition in a phosphorus-limited Mediterranean shrubland

Zhaobin Mu, Dolores Asensio, Jordi Sardans, Romà Ogaya et autres

Understanding soil biogeochemical responses to increased nitrogen (N) deposition is essential for assessing and mitigating the impacts of global environmental change on terrestrial ecosystems. However, the effects of N addition on key soil elements—those critical for ecosystem productivity and pollution dynamics—remain insufficiently …

Data from: Community complexity modulates the predictive power of demographic metrics on plant species resilience to disturbances in a distributed grassland experiment

DRAGNet, Elizabeth T. Borer, Eric W. Seabloom, Ingrid J. Slette et autres

A subset of a larger data set collected by the distributed grassland network Disturbance and Recovery Across Grasslands Network (DRAGNet). Grassland plant species percentage cover values are collected at the plot level across 40 sites of the network. This data covers the …

Data from: Anthropogenic disturbance expands the climatic limits of annual plant dominance

DRAGNet, Rebecca Abney, Mahmoud AlHarbi, Dana M. Blumenthal et autres

This dataset contains plant community data collected as part of the Disturbance Response Along Global Nutrient (DRAGNet) experiment, a globally distributed grassland experiment testing the independent and interactive effects of above-ground disturbance and NPK nutrient addition on plant communities. Data were collected …

Beyond N and P fertilization: Tropical ground hexapod communities are tied to micronutrients

Miquel Ferrín, Josep Peñuelas, Dolores Asensio, Laëtitia Bréchet et autres

Human-induced inputs of nitrogen (N) and phosphorous (P) disrupt global biogeochemical cycles and life itself. And yet there is no consensus on whether micro- or macronutrients are the main drivers of soil community assemblages. Tropical forests allow us to trace the response …

Drought intensity and duration interact to magnify losses in primary productivity

Timothy Ohlert, Melinda D. Smith, Scott L. Collins, Alan K. Knapp et autres

As droughts become longer and more intense, impacts on terrestrial primary productivity are expected to increase progressively. Yet, some ecosystems appear to acclimate to multiyear drought, with constant or diminishing reductions in productivity as drought duration increases. We quantified the combined effects …

World‐wide impacts of climate change and nitrogen deposition on vegetation structure, composition, and functioning of shrublands

Daijun Liu, Chao Zhang, Romà Ogaya, Nezha Acil et autres

Environmental changes and their effects are among the most pressing topics of today's ecological research. Shrublands, although widespread across the globe, remain understudied in this respect. We conducted a global meta-analysis of 81 shrubland sites subjected to experimental warming, shifts in precipitation …

The Global Spectra-Trait Initiative: A database of paired leaf spectroscopy and functional traits associated with leaf photosynthetic capacity

Julien Lamour, Shawn Serbin, Alistair Rogers, Kelvin Acebron et autres

Abstract. Accurate assessment of leaf functional traits is crucial for a diverse range of applications from crop phenotyping to parameterizing global climate models. Leaf reflectance spectroscopy offers a promising avenue to advance ecological and of robust hyperspectral models for predicting leaf photosynthetic …

Micronutrients are drivers of abundance, richness, and composition of soil insect communities in tropical rainforests

Miquel Ferrín, Dolores Asensio, Albert Gargallo‐Garriga, Oriol Grau et autres

Abstract Communities of soil insects in tropical rainforests are among the richest and most complex, but the mechanisms structuring them remain mostly unknown. Identifying whether nutrient availability plays a relevant role in the assembly of these communities poses several challenges due to …
