Consensus Techniques for Unsupervised Binary Change Detection Using Multi-Scale Segmentation Detectors for Land Cover Vegetation Images

Remote Sensing, 2023
Change detection in very-high-spatial-resolution (VHR) remote sensing images is a very challenging area with applicability in many problems ranging from damage assessment to land management and environmental monitoring. In this study, we investigated the

From leaves to defenders: How the amount and dispersion of leaf damage affect extrafloral nectar production and ant‐mediated protection in wild cotton

Ecological Entomology, Volume 51, Issue 2, Page 395-404, April 2026.
Extrafloral nectar mediates interactions among plants, ants and herbivores; its contingency on damage amount and within‐plant uniformity is poorly understood. Here, we explore these factors in wild cotton (Gossypium hirsutum). Herbivory amount drove increases in extrafloral nectar induction per nectary, whereas within‐plant variability in damage ...

Spatial Resolution Impact Assessment for Long‐Term Population Monitoring of Adélie Penguin Guano

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Adélie penguins (Pygoscelis adeliae) are key indicators of the Antarctic ecosystem, and remotely sensed guano stains offer an efficient means of estimating breeding abundance. Landsat medium‐resolution (MR) imagery enables long‐term monitoring through its archive.

Forwarding forest restoration: Seven key socio‐ecological issues for advancing forest restoration in a world in flux

People and Nature, Volume 8, Issue 3, Page 569-581, March 2026.
Abstract Restoring forests can help conserve biodiversity, mitigate climate change and enhance human well‐being. Despite financial and political support for global forest restoration initiatives, projects continue to face persistent challenges and trade‐offs between environmental, climatic and socio‐economic goals.

Two orders of wall‐to‐wall geographic data

Area, Volume 58, Issue 1, March 2026.
Short Abstract The use of the term ‘wall‐to‐wall’ to describe geographically extensive data without any singular definition in the remote sensing and geographically related analysis. This work presents an assessment of the application of the term in the scientific literature. Abstract From personal observations of recent published works, the term “wall‐
