Reindeer grazing induces spatial and functional shifts in root systems of boreal pine forests

Oikos, EarlyView.
The spatial distribution of roots, laterally and vertically, is critical for nutrient and water uptake and for driving root‐associated carbon inputs and turnover. Large herbivores, such as reindeer, influence ecosystems belowground by altering aboveground vegetation composition and soil microclimate.

Remote sensing and citizen science for habitat mapping: A machine learning approach to lowland heathland in Surrey, UK

People and Nature, EarlyView.
Abstract In a time of extensive global biodiversity loss, conservation efforts increasingly rely on high‐resolution, accurate, up‐to‐date habitat maps to guide decision‐making and strategic interventions. Many products have been developed in response, using machine learning (ML) methods to automate habitat classification, often relying on satellite ...

Dwarfing of fruit trees: from old cognitions to new insights

Plant dwarfing is a key agronomic trait, often characterized by shortened internodes and increased branching and leaf production, which improves lodging resistance and facilitates intensive crop planting. In fruit crops, dwarfing promotes dense planting,

Dwarfing genes, water-use efficiency and agronomic performance of spring wheat

, 1996
The Rht1 and Rht2 dwarfing genes have been used extensively to reduce height in wheat (Triticum aestivum L.). The Rht3 gene is also a potent dwarfing gene.

Modeled Subsidence of Permafrost Terrain 2025–2050: North‐Central Alaska

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT A large fraction of the Alaska terrain is underlain by regolith that contains excess ice (ice that in volume exceeds the natural pore space). Possible loss of excess ice would lead to ground subsidence, which in turn would disturb and destabilize the ground surface.

Evaluating Testability of Permafrost Models Through Physical and Thermal Testing in Complex Mountain Terrain, Yukon, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Due to its subsurface nature, permafrost cannot be directly observed with the naked eye or optical remote sensing. Consequently, accurately describing its distribution and thermal state is challenging. This is especially true in vast, remote environments, where obtaining comprehensive field data is demanding or improbable.

ZmCals12 impacts maize growth and development by regulating symplastic transport

Journal of Integrative Agriculture
Carbohydrate partitioning from source to sink tissues is essential for plant growth and development. However, in maize (Zea mays L.), the molecular mechanisms by which callose synthase genes regulate this process remain largely unexplored.

Integrating SfM, LiDAR and TLS for High‐Resolution Monitoring of Palsa Surface Changes and Degradation Dynamics

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Understanding fine‐scale surface changes is crucial for quantifying ecosystem dynamics and detecting landscape changes. Palsas, comparably small peatland elevations with an ice‐rich permafrost core, undergo natural cycles of growth and degradation. They can also serve as indicators of climate change in subarctic regions. Because they typically

DNA marker for oat dwarfing gene

, 2004
Short and stiff straw is one of the principal aims in oat cultivar breeding. Some dwarfing genes are available for backcrossing programmes. Selection efficiency could be improved by marker assisted selection (MAS) especially when the dwarfing gene is ...
