Evaluating methods for high‐resolution, national‐scale seagrass mapping in Google Earth Engine

Remote Sensing in Ecology and Conservation, EarlyView.
Marine habitat mapping using satellite imagery can provide baseline and monitoring data across large spatial scales and in remote locations globally. This study evaluates how key methodological choices influence the accuracy of open‐source (for non‐commercial use), cloud‐based satellite mapping workflows for seagrass meadows in the Maldives.

Conservation implications of shifting habitat use in migrating insects: Selection patterns in a threatened damselfly show that season‐specific actions are needed

Insect Conservation and Diversity, EarlyView.
Well‐preserved heathlands of NW Italy are the main overwintering habitat of Sympecma paedisca, while grassy margins in farmland are used only in summer and are avoided from autumn onwards. Grassy margins in farmland act as corridors during the species' migrations between its breeding (ricefields) and overwintering (lowland heathlands) grounds ...

Entre étalement et densification : une approche fine de l’urbanisation littorale sur la Côte bleue, Provence

Cybergeo, 2016
To assist spatial planning and environmental management policies in coastal areas, the monitoring of urban sprawl and the characterization of the evolution of built-up areas are essential prerequisites.

Unlocking landscape transient dynamics: Integrating traditional ecological knowledge for enhanced analysis of land‐use changes and forest expansion in a Mediterranean ecosystem

People and Nature, Volume 8, Issue 2, Page 283-300, February 2026.
Abstract The Industrial Revolution triggered rural abandonment in Europe and had a profound impact on land configuration and ecosystem dynamics, mainly the growth of forests at the expense of open agricultural habitats. However, rural abandonment has been asynchronous in space and time, depending on regional socio‐economic dynamics.

Comparison of drone and ground surveys for the detection of a rare plant in a fragile ecosystem

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
We compared the accuracy, time, and financial costs of drone and ground surveys for the detection of wood lilies (Lilium philadelphicum) in an endangered alvar ecosystem. We found that the drone surveys detected 73%–78% of the plants found in the ground surveys, but that this type of survey was more expensive and time consuming than the ground survey ...

New Paradigms for Geomorphological Mapping: A Multi-Source Approach for Landscape Characterization

Remote Sensing
The advent of geomatic techniques and novel sensors has opened the road to new approaches in mapping, including morphological ones. The evolution of a land portion and its graphical representation constitutes a fundamental aspect for scientific and land ...

Fracture of Podolia caves in the aspect of rotational and tectonic causes of formation

Геофизический журнал, 2012
Problems of origin of speleoinitiating fracturing of Podolia cave networks are discussed applying structural analysis of labyrinthes, photointerpretation relief lineaments and conception of planetary (rotation-initiated) fracturing.

The legacy of pine plantations on fire severity

Journal of Applied Ecology, Volume 62, Issue 11, Page 3156-3168, November 2025.
Our findings provide quantitative evidence that pine plantations can exacerbate fire severity under contemporary climate conditions, and that, once burned, these areas seldom recover. Effective spatial planning and management of tree plantations is therefore essential in order to promote more sustainable fire regimes in Mediterranean ecosystems ...

Fotointerpretación geomorfológica del curso bajo el río Grande de Santiago, Nayarit

Investigaciones Geográficas, 1979
The principal geomorphologic modifications of the fluvialbed and their effects are analized in the low course of river Grande de Santiago, in the last 37 years, through the comparative photointerpretation of aerial images taken in different dates.
