Dynamic Reconstruction of Atomically Dispersed Copper Catalysts for CO2 Reduction: From In Situ Observations to Rational Design

open access: yesEcoEnergy, EarlyView.
Dynamic reconstruction transforms atomically dispersed Cu catalysts into authentic working‐state active phases during CO2 electroreduction. By integrating operando characterization, multiscale simulations, and AI‐assisted predictive modeling, this review establishes a framework for understanding, predicting, and rationally engineering catalyst ...

Aridity thresholds Reveal transitions in dominant drivers of partitioned Water–Carbon coupling across Central Asian drylands

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
Intensifying global aridification is reshaping the water–carbon balance in dryland ecosystems, yet when and how this coupling reaches critical thresholds remains poorly understood—posing major uncertainties for predicting ecosystem resilience under ...

How to reduce sampling error in species population monitoring: from theory to methods

open access: yesEcography, EarlyView.
Progress towards national and international targets to halt and reverse declines in species' abundances will be assessed using multispecies indicators (MSIs). A distinction must be drawn between two MSIs. One is the ideal, but unobserved, MSI that would have been measured had all species and sites within the scope of the target been sampled.

A global latitudinal decline in breeding site fidelity emerges from a single biome

open access: yesEcography, EarlyView.
Species that breed in multiple years can either return to the same location to reproduce between seasons or disperse to a different location. Previous studies have shown that breeding site fidelity varies with species‐ and individual‐specific traits, but much of the observed variation remains unexplained.

Spatio-temporal similarity between stations.

open access: yes
Accurate bike-sharing demand prediction is crucial for bike allocation rebalancing and station planning. In bike-sharing systems, the bike borrowing and returning behavior exhibit strong spatio-temporal characteristics. Meanwhile, the bike-sharing demand

Rising, falling, stalling: complex biodiversity trajectories in English rivers

open access: yesEcography, EarlyView.
Freshwater ecosystems face intense anthropogenic pressures. Yet in parts of Europe, including the UK, studies have documented widespread increases in macroinvertebrate diversity following investments to improve water quality. More recent analyses, however, suggest that these gains have slowed, plateaued, or even reversed. Despite increasing recognition

Regional climate model assessment via spatio-temporal modeling

open access: yes, 2018
In order to adapt to a changing climate, policymakers need information about what to expect for the climate system. Typically local information about certain aspects of the climate system comes from regional climate models as well as from ...

Spatio-Temporal Patterns of the Modified "Rock-Paper-Scissors" Model [PDF]

open access: yes, 2003
Spatio-temporal patterns of the modified "rock-paper-scissors" model (R-P-S model) in 1-D lattice were investigated. We extended the simple R-P-S model where 3-species compete each other by introducing an effect of random spawn.

Combining paleoecology and modeling to explore cascading disturbances in forest ecosystems

open access: yesEcography, EarlyView.
Climate‐induced cascading disturbance interactions pose a major challenge to the sustainable provision of forest ecosystem services to society. Developing a deeper understanding and enhanced capacity to simulate these interactions is essential for identifying disturbance‐induced tipping points in forest ecosystems, and for improving management in ...

Wolves and humans both shape patterns of deer browsing in a temperate forest ecosystem of Central Europe

open access: yesEcography, EarlyView.
Predator–prey interactions can trigger behavioural responses in ungulates, influencing their space‐use and foraging behaviour and, in turn, indirectly affecting browsing pressure. Changes in browsing pressure can affect plant recruitment and species composition, shaping forest regeneration through predator‐mediated trophic cascades.
