Extracting massive ecological data on state and interactions of species using large language models

This study uses large language models to extract ecological interactions from 83,910 scientific papers, creating a network of 144,402 interactions between 36,471 taxa with high precision and sensitivity.

Integrated reanalysis of global riverine fish eDNA datasets shows robustness and congruence of biodiversity conclusions

This study reanalyzes global riverine fish eDNA datasets to show that biodiversity conclusions are robust despite varying bioinformatic workflows and reference databases.

Small habitat patches can be the largest contributors to urban biodiversity across taxonomic groups

The paper evaluates how habitat patch size, quality, and connectivity affect urban biodiversity across taxa, finding small patches significantly contribute to species richness and community diversity.

Tracking the phenology of riverine insect communities using environmental DNA

This study shows that eDNA can capture seasonal changes in aquatic insect communities across a river catchment, revealing phenological trends and species dynamics over time.

Changing seasonality and phenology mediate the effects of migration across meta-ecosystems

This study shows how seasonal changes and migration timing affect species coexistence and biomass production across ecosystems.

Complementarity of ecosystem types drives landscape-wide productivity in North America

The paper shows that diverse ecosystems in North America are more productive and stable under drought, driven by complementarity among ecosystem types.

Biodiversity and riparian forests are mutual biological drivers of ecosystem functions in temperate and tropical streams

The paper manipulates biodiversity and riparian forests to show their positive effects on aquatic-terrestrial ecosystem functions in both temperate and tropical streams.

Positive effects of landscape diversity on vegetation productivity at the kilometer scale

The paper investigates how landscape diversity affects vegetation productivity at the kilometer scale using satellite data and land cover analysis, finding a universal association between landscape diversity and productivity.

Globally unified analysis of riverine eDNA reveals common associations of fish biodiversity with drainage characteristics

This study uses global eDNA data to show how riverine fish biodiversity relates to drainage characteristics, revealing climate and human activity effects vary by biodiversity facet and catchment size.

Biodiversity modulates the cross-community scaling relationship in changing environments

The paper tests how temperature and biodiversity affect the size-abundance relationship in protist communities, finding context-dependent shifts in the scaling slope.

A global synthesis on land-cover changes in watersheds shaping freshwater detrital food webs

This study synthesizes global data showing that land-cover changes in watersheds negatively impact freshwater detrital food webs by reducing biodiversity and ecosystem processes.

Spatial Biodiversity Indicators and a Composite Index for Conservation Prioritization in Switzerland

The paper develops spatial biodiversity indicators and a composite index for conservation planning in Switzerland using habitat suitability data across 17 taxonomic groups and 7,500 species.

Food-web coupling by mobile consumers has individual to ecosystem level effects

This study shows that mobile consumers affect ecosystem biomass and their own fitness, with effects dependent on community composition.

Regulation of trophic architecture across spatial scales in a major river network

The paper examines how environmental and anthropogenic factors influence trophic structure across spatial scales in the Swiss Rhine river catchment using integrative path analysis.

Worldwide cross-ecosystem carbon subsidies and their contribution to ecosystem functioning

This study quantifies global carbon subsidies between ecosystems, showing their significant role in ecosystem functioning and highlighting gaps in current understanding.

Bottom-up and top-down control of dispersal across major organismal groups: a coordinated distributed experiment

The paper tests how bottom-up and top-down controls affect dispersal across species and shows their impacts on community dynamics.

Population turnover reverses classic island biogeography predictions in river-like landscapes

The paper examines how population turnover in river-like landscapes reverses traditional island biogeography predictions.

The Ecological Forecast Horizon, and examples of its uses and determinants

The paper introduces the ecological forecast horizon as a framework to assess the limits of ecological predictions across time, space, and phylogeny, using case studies to illustrate its applications and determinants.
