Low Latency Global Carbon Budget Reveals Late 2024 Carbon Losses and Contrasting Early 2025 Land Sink Recovery Signals

open access: yesAdvanced Science, EarlyView.
Low latency carbon budget estimates for July 2024–June 2025 combine atmospheric CO2 growth rates, fossil emissions, ocean uptake, DGVM land fluxes, and OCO‐2 inversions. The budget shows that late‐2024 land carbon losses dominate the annual anomaly, while early‐2025 recovery differs between bottom‐up models and top‐down inversions, especially in ...

The Assessment of Time–Area and Clark Instantaneous Unit Hydrograph Models in Estimating Flood Discharge in Bazoft Karoon [PDF]

open access: yesنشریه جغرافیا و برنامه‌ریزی, 2012
One of the main objectives in hydrology is rainfall–runoff forecasting systems for determination of flood hydrograph in outlet of a watershed. Flood discharge could be estimated using rainfall-runoff models, which explain hydrological phenomena for un ...

Tools for agricultural drought detection in the frame of Drought Management Centre for Southeastern Europe – DMCSEE

open access: yesActa Agriculturae Slovenica, 2012
Numerous specialized indices have been proposed to assess drought severity, but the precise quantification of drought is a difficult challenge. The purpose of this paper is to evaluate two indices: the well known Standardized Precipitation Index (SPI ...

Functional–Taxonomic Scaling Resolves Conflicting Average Genome Size Estimates Across Environmental Gradients

open access: yesAdvanced Science, EarlyView.
Based on genome size‐functional breadth theory, we introduce and validate a framework that adjudicates conflicting average genome size (AGS) estimates by testing which estimate yields a gap between scaled functional diversity and scaled taxonomic diversity that is consistent with the expected positive association between genome size and gene functional

Dual Repression by IPA1 Fine‐Tunes OsbZIP79‐Mediated Salt Tolerance in Rice

open access: yesAdvanced Science, EarlyView.
Dual repression by IPA1 fine‐tunes OsbZIP79‐mediated salt tolerance in rice: direct transcriptional inhibition under normal conditions and salt‐induced degradation under stress. This dual mechanism activates OsbZIP79 to regulate Na+/K+ homeostasis and redox balance via downstream genes, enabling optimal salt stress response.

Integration of the D‐Genome Reshapes Gene Transcription, Chromatin Architecture, and Metabolome of Allohexaploid Wheat, Leading to Enhanced Environmental Adaptability

open access: yesAdvanced Science, EarlyView.
Integration of the D‐genome reshapes gene transcription, chromatin architecture, and the metabolome of hexaploid wheat, leading to enhanced adaptability to salt, UV‐B, and alkali stress. ABSTRACT The hybridization‐led integration of the D‐genome into domesticated tetraploid wheat gave rise to allohexaploid wheat, the most cultivated wheat globally ...

Responses of Young Tea (Camellia Sinensis) Clones to Drought and Temperature. I. Yield and Yield Distribution [PDF]

open access: yes, 1996
The yield responses to drought and temperature of six contrasting tea clones were studied in a line-source irrigation experiment in Southern Tanzania. The selected clones, all commercially and/or scientifically important in eastern Africa, embrace a ...

Optimized Land–Water Management Expands Afforestation Potential Under Land and Human Water‐Use Constraints

open access: yesAdvanced Science, EarlyView.
Human water demand constrains China's feasible afforestation potential more strongly than is commonly recognized, and future climate change further intensifies this limitation. Integrating land‐use optimization with water‐saving measures substantially expands feasible afforestation area and associated carbon sinks, revealing a practical pathway to ...

Impact of drought on grape yields in the Western Cape, South Africa [PDF]

open access: yes, 2014
Includes bibliographical references.Droughts remain a threat to grape yields in South Africa. Previous studies on the impact of climate variability on grape yield in South Africa have focussed on either the rainfall or the impact of temperature on the ...
