Climate Controls on Carbon Dioxide Fluxes in a High‐Elevation Grassland

open access: yesGlobal Change Biology Communications, Volume 1, Issue 2, June 2026.
Climate change is significantly influencing high‐elevation grasslands, possibly unbalancing CO2 exchanges and the sink‐source dynamics. Cumulated heat available for plant growth and vegetation cover were identified as the main controllers of phenological development and, via direct or mediated effects, of CO2 fluxes (ER and GPP).

First Direct Observations of Internal Flow Structures in a Powder Snow Avalanche: Turbulence, Instability and Particle Distribution

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Powder snow avalanches are highly dynamic, multiphase gravity‐driven flows typically composed of a dense basal layer overlain by airborne layers in which snow particles are suspended within a turbulent air phase. Despite extensive work on related systems such as pyroclastic density currents and turbidity currents, all gravity current studies ...

Reactivation Mechanism of Dormant Earthflows: Insights From the San Benedetto Landslide (Northern Apennines, Italy)

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Earthflows are landslides in fine‐grained materials that alternate long dormant phases of very slow movement with short paroxysmal stages of rapid motion. These rapid phases are highly destructive, often causing severe damage to buildings and infrastructure.

From Geoportals to Geographic Knowledge Portals

open access: yesISPRS International Journal of Geo-Information, 2013
We present the application of Latent Semantic Analysis (LSA) in combination with recommender systems, in order to enhance discovery in geoportals. As a basis for discovery, metadata of spatial data and services, as well as of non-spatial resources, such as documents and scientific papers, is created and registered in the catalogue of the geoportal ...

Beyond species loss: Community reshuffling shapes biodiversity along the urban–rural gradient

open access: yesJournal of Applied Ecology, Volume 63, Issue 6, June 2026.
Our results indicate that species turnover is a general ecological mechanism shaping vertebrate communities along the urban gradient, driven by taxon‐ and species‐specific responses to environmental and spatial features. Community differences primarily reflect habitat suitability rather than dispersal limitation, highlighting the potential of targeted ...

Sustainable Livestock Decisions in a Post‐Conflict Frontier: Evidence From Colombia's Orinoquía

open access: yesJournal of Agricultural Economics, Volume 77, Issue 2, Page 304-319, June 2026.
ABSTRACT The Orinoquía region is one of Colombia's principal agricultural frontiers and has been shaped by long‐standing armed‐conflict dynamics that continue to influence land governance, producer incentives, and investment decisions. Efforts to promote sustainable cattle production emphasize two key practices: sustainable pasture management ...

A Spatial Data Infrastructure Integrating Multisource Heterogeneous Geospatial Data and Time Series: A Study Case in Agriculture

open access: yesISPRS International Journal of Geo-Information, 2016
Currently, the best practice to support land planning calls for the development of Spatial Data Infrastructures (SDI) capable of integrating both geospatial datasets and time series information from multiple sources, e.g., multitemporal satellite data ...

Spatial Metadata Usability Evaluation

open access: yesISPRS International Journal of Geo-Information, 2020
Spatial metadata is a critical part of any spatial data infrastructure, which enables the organising, sharing, discovery and use of spatial data. This paper highlights a knowledge gap in the usability of the metadata systems for the end–users.
