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

open access: yes, 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.

Designing Public Transportation Services for Car‐Dependent Rural Destinations: An Application in the Case of the Ebro Delta (Spain)

open access: yesInternational Journal of Tourism Research, Volume 27, Issue 3, May/June 2025.
ABSTRACT This paper proposes a method for developing alternative transportation policies in car‐dependent rural areas, supporting the United Nations' decarbonisation goals and aiming to mitigate the impacts of drive‐tourism in sensitive regions. After analysing tourist travel patterns, examining the proliferation of parking lots, identifying key ...

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

open access: yesGeographica 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.

Key Landscape Factors Influencing Stream Physical Habitats Across the Brazilian Neotropical Savanna

open access: yesEcohydrology, Volume 18, Issue 3, April‐May 2025.
ABSTRACT Improved management of small headwater streams in the Cerrado (Neotropical Savanna) biome in Brazil is necessary given the significant landscape transformations caused by anthropogenic activities in recent decades. Thus, we aimed to determine the relative influence of the leading natural landscape features and anthropogenic pressures on the ...

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

open access: yesEarth 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.

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

open access: yesInvestigaciones 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.

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

open access: yesJournal 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.

Standardised Drone Procedures for Phytosociological Data Collection

open access: yesApplied 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:

Enfrichement des côtes rocheuses : analyse de la dynamique du paysage et de la végétation

open access: yesM@ppemonde
This study examines two coastal post-agricultural lands of the commune of Moëlan-sur-Mer affected by a recultivation project. It aims to interrogate the landscape heterogeneity and specific diversity of these abandoned lands and their nearby areas.
