INDITEK‐2.0: A Bayesian inverse modelling framework for mechanistic evolutionary processes

Methods in Ecology and Evolution, EarlyView.
Abstract Mechanistic eco‐evolutionary models are powerful tools for understanding how life diversified over geological timescales, yet estimating their parameters remains a key challenge. The high computational requirements of these models make probabilistic inversion methods unfeasible.

Quantifying the Impacts of Anthropogenic Activities and Climate Variations on Vegetation Productivity Changes in China from 1985 to 2015

Remote Sensing, 2020
Accurate assessment of vegetation dynamics provides important information for ecosystem management. Anthropogenic activities and climate variations are the major factors that primarily influence vegetation ecosystems.

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Warming of alpine tundra enhances belowground production and shifts community towards resource acquisition traits

Ecosphere, 2020
Climate warming is expected to stimulate plant growth in high‐elevation and high‐latitude ecosystems, significantly increasing aboveground net primary production (ANPP).

Climate change impacts on net primary production (NPP) and export production (EP) regulated by increasing stratification and phytoplankton community structure in the CMIP5 models [PDF]

Biogeosciences, 2015
Abstract. We examine climate change impacts on net primary production (NPP) and export production (sinking particulate flux; EP) with simulations from nine Earth system models (ESMs) performed in the framework of the fifth phase of the Coupled Model Intercomparison Project (CMIP5). Global NPP and EP are reduced by the end of the century for the intense

Threat Integration Model for Sagebrush (TIMS): A framework for using spatial decision support tools for strategic management of invasive annual grasses and conifers in sagebrush ecosystems

Conservation Science and Practice, EarlyView.
The Threat Integration Model for Sagebrush (TIMS) combines multiple spatial decision support tools to provide a unified, actionable map of sagebrush ecosystem conditions across the western United States. TIMS improves upon existing tools by including multiple threats in the same map (invasive annual grass [IAG] and conifer encroachment), characterizing

Recent plant photosynthate as a driver of ecological and evolutionary processes

New Phytologist, EarlyView.
Timeline of key eco‐evolutionary outcomes arising from belowground allocation of recent plant photosynthate from shoots. Summary Plants rapidly allocate carbon from photosynthesis belowground via root exudates and root‐associated microorganisms. Here we synthesise recent evidence of our understanding of the consequences of this ‘fast’ pathway of recent

Infrastructure as Inherited Knowledge: Artificial Intelligence and the Governance of Long‐Life Infrastructure

Journal of Critical Infrastructure Policy, Volume 8, Issue 1, Spring/Summer 2027.
ABSTRACT Epistemic orphaning, responsibility drift, loss of institutional memory, and non‐stationarity are not new problems in infrastructure governance—they have accompanied long‐life infrastructure throughout its history. What artificial intelligence changes is not the existence of these problems but their scale, opacity, and the structural ...

Distinct environmental controls on above- and below-ground net primary productivity in Northern China’s grasslands

Ecological Indicators
Grasslands, which cover approximately 40 % of the global land surface, are crucial to the global carbon cycle due to their substantial carbon storage capacity and sensitivity to environmental changes.

Translocated Clam Retention and Effects on Ecosystem Functions Across a Gradient of Environmental Stress

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 4, December 2026.
Estuarine ecosystems are experiencing increasing land‐derived stress, bringing sediments, excess nutrients and contaminants. Once degraded, disturbed soft sediment ecosystems can take years to recover because long‐lived, functionally important species that aid recovery are lost.
