Constructing Synthesizable Evaluations of Technical Interventions to Reduce Wildlife‐Caused Agricultural Losses 构建易用于证据整合的野生动物致农业损失缓解措施成效评估

Integrative Conservation, EarlyView.
A framework with eight key components to assess the effectiveness of technical measures to reduce wildlife‐caused agriculture loss. ABSTRACT Technical interventions to reduce wildlife‐caused agricultural losses (e.g., crops, livestock, and fisheries) are essential for human‐wildlife coexistence.

Where were all the trees? Computer vision meets landscape history to unlock the potential of historical Ordnance Survey maps

People and Nature, EarlyView.
Abstract The first edition of the Ordnance Survey's 1:2500 County Series is marked with treed areas, such as woodlands and orchards, and, remarkably, freestanding trees. Consequently, it is an unparalleled source of information on the distribution of trees across Britain in the mid‐late nineteenth century, when the maps were first surveyed. In order to

Assessing the Performance of Different Direct-Georeferencing with Large Format Digital Cameras [PDF]

, 2014
This paper provides an independent investigation into the quality, performance and reliability of the Direct Georeferencing (using in-flight control GPS and IMU systems to measure the exterior orientation parameters) with the new photogrammetric digital ...

Adaptive Re-weighted Block Adjustment for Multi-Coverage Satellite Stereo Images without Ground Control Points

IEEE Access, 2019
Georeferencing satellite imagery is the basis for mapping and other subsequent processing in photogrammetry and remote sensing. Traditional georeferencing methods, which require adequate and well-distributed ground control points (GCPs), are time ...

Spatio‐temporal patterns, associated factors and mitigation of tiger and leopard attacks on people in western Himalayas

People and Nature, EarlyView.
Abstract Coexistence with large carnivores becomes extremely difficult in areas where there are large number of attacks on humans. An understanding of the factors that explain the spatio‐temporal context of such attacks would guide policy and management to mitigate conflict, conserve carnivores and assist coexistence.

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

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

Within‐tree spatial heterogeneity of sap flow velocities and wood properties and its effect on the uncertainty of tree level sap flux estimates

PLANTS, PEOPLE, PLANET, EarlyView.
As forests are important for biodiversity and recreation and provide vital resources globally, it is essential that their health can be accurately monitored, for example, by using sap flow probes to measure tree water uptake. We investigated whether sap flow measurements might differ at various locations within the same tree due to variation in wood ...

Evolution of photoperiod insensitivity drove the westward expansion of broomcorn millet

PLANTS, PEOPLE, PLANET, EarlyView.
This research highlights how ancient farming communities adapted crops to challenging environments, enabling the spread of agriculture across Eurasia. By demonstrating that broomcorn millet evolved reduced sensitivity to day‐length, the study explains how this crop could support food production in regions with short growing seasons and long summer days.
