Qualitative and quantitative photogrammetric techniques for multi-temporal landslide analysis

Annals of Geophysics, 2006
The results of two survey methods, geological photointerpretation and historical photogrammetry, are compared in order to evaluate the temporal evolution of a unstable slope located in the Tuscan-Emilian Apennines (Italy). Historical aerial photos of the

Vegetation and channel adjustment trajectories in cold regions: The effects of ice disturbances in two Gaspesian rivers

Earth Surface Processes and Landforms, Volume 50, Issue 5, April 2025.
This study explores the role of ice jam regimes on the biogeomorphological dynamics of two cold‐climate rivers. The analysis of vegetation and channel planform adjustments on a 60‐year timescale showed that the ice jam regime had notable impacts on vegetation successional dynamics, which further modulate geomorphological changes.

Increased proportion of exclusion netting in the landscape affects pest damage in unnetted apple orchards

Journal of Applied Ecology, Volume 62, Issue 4, Page 790-800, April 2025.
This study is the first to reveal that nets significantly impact pest dynamics on the scale of agricultural landscapes. We recommend landscape‐scale coordination in the deployment of nets, along with additional protective measures to mitigate their unintended effects on pests at the local and landscape scales.

Approche comparée de méthodes de classification d'images aériennes : une étude de cas [PDF]

Geographica Helvetica
L'exploitation d'images aériennes ou satellitales à très haute résolution (< 5 m) remet en cause des procédures de Classification qui pourtant avaient fait leur preuve pour l'exploitation d'images à plus faible résolution.

Eelgrass Distribution in the Great Bay Estuary and Piscataqua River for 2013 [PDF]

, 2014
Eelgrass distribution and cover in Great Bay, Little Bay, and the Piscataqua River Estuary were mapped from aerial photography acquired on August 24, 2013. The total area of eelgrass beds with 10% or greater cover was 1683.4 acres.

Standardised Drone Procedures for Phytosociological Data Collection

Applied Vegetation Science, Volume 28, Issue 2, April/June 2025.
ABSTRACT Aims Phytosociological maps are crucial for biodiversity conservation. Supervised mapping with machine learning demands high‐quality reference data that field surveys alone cannot provide. This study evaluates drone‐based procedures for phytosociological data collection, comparing them with field surveys. The research questions are as follows:

Structural relief and karst in the Sierra del Aramo (Asturian Central Massif)

Investigaciones Geográficas, 2019
The structural and karst forms of the Sierra del Aramo are analysed, especially the lithological and tectonic factors that determine the morphostructural organisation of the relief.

Paleo‐Earthquake Fingerprints and Along‐Strike Slip Variation of the Silent Mt. Morrone Normal Fault (Central Italy): A Structural‐Geochemical Approach

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 2, February 2025.
Abstract This study provides insights into the tectonic evolution of the normal Mt Morrone Fault System (MMFS) in Central Italy and highlights the utility of multidisciplinary approaches in reconstructing the seismic history of dormant fault systems. The MMFS comprises two parallel normal faults that traverse the western slope of Mt.

Multiple Phytophthora species associated with declining wild olive trees in Sardinia, Italy

Plant Pathology, Volume 74, Issue 2, Page 465-475, February 2025.
This study provides new insights into the role of multiple Phytophthora species associated with widespread and severe decline of wild olive trees in Sardinia (Italy). Abstract Wild olive represents one of the most iconic woody plants in the Mediterranean Basin.
