Towards stochastic simulation of crop yield: a case study of fruit set in sweet pepper [PDF]

, 2010
Crop growth simulation models are widely used in research and education, and their use in commercial practice is increasing. Usually these models are deterministic: one set of input values always gives the same output of the model.

Weeds in a changing climate: Competitors or service plants?

PLANTS, PEOPLE, PLANET, EarlyView.
Reducing herbicide use and preparing agroecosystems for climate change are two top priorities on the global policy agenda. Here, we explore whether these two challenges can be tackled simultaneously. While weeds are generally considered a threat to crop production, we show that weeds can help overcome climate change challenges in agroecosystems ...

Low‐order system for eddy growth in the storm track

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Reanalysis data for the North Atlantic storm track are used to construct a low‐order model that optimally fits the observed interaction between the mean flow and baroclinic eddies. The resulting model is a certain type of predator–prey model. It explains various properties of the storm track, including why eddies grow linearly with the Eady growth rate,

A review of empirical dam breach models

River, EarlyView.
Abstract Dam breach modelling is central to flood risk assessment, yet the empirical models commonly used for estimating breach parameters display considerable variability and uncertainty. This review evaluates the performance of widely applied empirical dam breach models and identifies those that consistently show lower uncertainty, such as the ...

Sustainability and Corporate Performance in the Global South: The Influence of the Environmental Pillar and Institutional Quality

Sustainable Development, EarlyView.
ABSTRACT Corporate sustainability in the Global South unfolds under heterogeneous institutional conditions, where firms face simultaneous pressures from global ESG standards and local governance constraints. This study examines the relationship between ESG‐aligned environmental practices and corporate financial performance, considering the moderating ...

Indigenous Relational Thought and Climate Crisis Response: Rethinking Human‐Environment Relations Beyond Technocratic Governance

Sustainable Development, EarlyView.
ABSTRACT Climate change is frequently framed as a technical problem of emissions, risk, finance, adaptation planning, and institutional coordination. This critical integrative review, supported by scoping‐informed searching and transparent eligibility and synthesis procedures, examines how selected Indigenous relational literatures can deepen climate ...

Symbols of Climate Action: Audit Labor and the Production of Carbon Credits

Economic Anthropology, EarlyView.
ABSTRACT Voluntary carbon markets (VCMs) are promoted as tools for financing climate mitigation, yet their effectiveness and credibility remain contested. This article examines how carbon credits are produced and destabilized as symbols of climate action, emphasizing the forms of ecological and audit labor that sustain their legitimacy.

The Study of Source-Sink Relations by Comparison of Weight and Grain in the Modern and Old Wheat Cultivars

Ikufīziyuluzhī-i Giyāhān-i Zirā̒ī, 2017
Seed filling in wheat is controlled by the availability of substrate (source strength), the capacity of the organs to utilize it for seed growth (sink strength). The aim of this research was to study source-sink relations in wheat, through seed weight and grain number in new and old wheat cultivars.

Why theory matters for causal inference? Rethinking endogeneity in entrepreneurship research

Strategic Entrepreneurship Journal, EarlyView.
Abstract Endogeneity in entrepreneurship research is often treated as a statistical complication addressable through advanced econometric tools. This commentary argues that such an approach overlooks a deeper issue: endogeneity is conceptual before it is statistical.

Fruit growth and photosynthesis are differentially affected by local variation in source/sink relations

, 2018
Tree crop load affects carbon acquisition as well as processes like floral induction or fruit growth. Nevertheless little is known about the impact of local variations of source / sink relationships on these processes variability within the tree.
