Extended Strahler Ordering to Distinguish Mapped River Channels From Overland Flow Pathways and Consistently Compare Digital Networks

River Research and Applications, EarlyView.
ABSTRACT Digital networks are virtual representations of freshwater systems that provide important inputs to, and mapping of, river classifications, simulation models, and quantitative data analyses for policy, planning, and management. Strahler order has often been used to characterize network configuration and as a proxy indicator of river channel ...

Model calculation of a radio communication line based on remote sensing data

Физика волновых процессов и радиотехнические системы
Background. In the process of functioning of modern complexes and specialized equipment in conditions of direct visibility between radio facilities, data transmission is not always possible, which significantly reduces the efficiency of the data ...

Suitable habitat of Himalayan wolf in Upper Mustang, Annapurna Conservation Area, Nepal

Wildlife Biology, EarlyView.
Decades ago, the Himalayan wolf Canis lupus chanco, a genetically distinct sub‐species of the gray wolf Canis lupus, faced persecution by local communities in the Nepalese Himalayas. Recently, wolf populations have returned and recolonized, sparking concerns about conflicts over livestock depredation, and emphasizing the urgent need for comprehensive ...

The Wind of Change: Mapping Wind Energy Growth and Multi‐Species Vulnerability in Sardinia, Mediterranean

Animal Conservation, EarlyView.
The rapid expansion of wind energy across the Mediterranean region calls for more advanced tools to assess and mitigate its impacts on biodiversity. In this study, we present an innovative approach combining 13‐year satellite imagery analysis and ecological modelling, to assess the spatiotemporal overlap between wind energy development and habitat ...

Assessment of ecosystem status in Mozambique and implications for environmental planning

Conservation Science and Practice, EarlyView.
We assess Mozambique's terrestrial ecosystems using the IUCN Red List of Ecosystems framework, showing that more than half of Mozambique's ecosystems are threatened, with impacts primarily concentrated in temperate subhumid grasslands and pyric tussock savannas.

Az SRTM-1 felszínmodell korrigálása Magyarországra [PDF]

Természetföldrajzi Közlemények, 2016
A közel globális lefedettséget nyújtó, szabadon hozzáférhető digitális felszínmodellek (pl. SRTM-1, SRTM-3, ASTER GDEM) széles körben elterjedt eszközei a modern földtudományi vizsgálatoknak. A kutatás során a 30 méter felbontású SRTM-1 modell korrigálását végeztük el Magyarország területére, szabadon hozzáférhető felszínborítási adatok és nyílt ...

Carbon finance initiatives can provide biodiversity benefits

Conservation Science and Practice, EarlyView.
We evaluated the biodiversity co‐benefits of a REDD+ initiative in the tropical forests of Sierra Leone and Liberia using a quasi‐experimental study design. Complementary measures from bioacoustics and DNA metabarcoding revealed that REDD+‐financed protected areas were associated with additional biodiversity benefits compared to control areas.

Natural Resources and Political Patronage in Africa: An Ethnicity Level Analysis

Review of Development Economics, EarlyView.
ABSTRACT We investigate the effect of resource discoveries on ethnicity‐level political patronage in Africa using a large geospatial dataset of 254 ethnic groups in 15 countries over the period 1960–2004. We find that the first (or single first) resource discovery in a virgin ethnic homeland increases the share of cabinet posts of that ethnicity.

Lineament mapping using sig and optical and radar remote sensing: The case of the Tafilalet plain (Southeastern Morocco) [PDF]

E3S Web of Conferences
This research focuses on the mapping of lineaments in the Tafilalet plain, located in south-eastern Morocco, using a combination of optical (Landsat 8), radar (Sentinel-1A) and 10 m resolution digital terrain model (SRTM) remote sensing.
