Application of Governance in spatial scales

open access: yesJournal of Applied researches in Geographical Sciences, 2022
"Governance" is one of the basic concepts that has attracted the attention of geo-political scientists, and there are contradictory views on this concept, which is one of the main and fundamentally important foundations of the science of geopolitics. The rule of law over higher power and superiority imply that no other legal authority is superior to it.

Observing Rivers With Varying Spatial Scales [PDF]

open access: yesWater Resources Research, 2019
AbstractThe National Aeronautics and Space Administration/Centre national d’études spatiales Surface Water and Ocean Topography (SWOT) mission will estimate global river discharge using remote sensing. Synoptic remote sensing data extend in situ point measurements but, at any given point, are generally less accurate.

Diversity and Structure of Parrotfish Assemblages across the Northern Great Barrier Reef

open access: yesDiversity, 2019
The structure and dynamics of coral reef environments vary across a range of spatial scales, with patterns of associated faunal assemblages often reflecting this variability.

Plant biodiversity assessment through soil eDNA reflects temporal and local diversity

open access: yesMethods in Ecology and Evolution, 2023
Several studies have shown the potential of eDNA‐based proxies for plant identification, but little is known about their spatial and temporal resolution.

Impervious surface extraction based on different methods from multiple spatial resolution images: a comprehensive comparison

open access: yesInternational Journal of Digital Earth, 2021
Many efforts have been devoted to extracting impervious surfaces based on different methods from multiple spatial resolution images. Differences in extraction methods and spatial resolutions are significant and have led to discrepant performances in ...

Spatial Scaling in Model Plant Communities [PDF]

open access: yesPhysical Review Letters, 2005
We present an analytically tractable variant of the voter model that provides a quantitatively accurate description of beta-diversity (two-point correlation function) in two tropical forests. The model exhibits novel scaling behavior that leads to links between ecological measures such as relative species abundance and the species area relationship.

The Question of Scale in Integrated Natural Resource Management

open access: yesEcology and Society, 2002
Lessons from integrated natural resource management (INRM) practiced at different scales are reviewed, with a focus on catchment management. INRM is complex, and many interactions have to be addressed.

Abundance of mycophagous arthropods present on different species of fungi in relation to resource abundance at different spatial scales

open access: yesEuropean Journal of Entomology, 2005
The abundance of Coleoptera, Diptera and Collembola on different species of fungi was investigated in relation to the size and abundance of fungal resources at different spatial scales; i.e., the size of the fungal fruiting body, the quality of resource ...
