Remotely sensed soil moisture to estimate savannah NDVI

PLOS ONE, 2018
Satellite derived normalized difference vegetation index (NDVI) is a common data source for monitoring regional and global ecosystem properties. In dry lands it has contributed to estimation of inter-annual and seasonal vegetation dynamics and phenology.

Assessing habitat suitability for black grouse broods at the bioregional scale

Wildlife Biology, EarlyView.
The black grouse Lyrurus tetrix, a galliform species emblematic of the European Alps, is currently threatened by habitat change, particularly given the closure of heathland linked to the rising tree line at higher altitudes. The presence of heathlands in good ecological condition is, however, imperative for the species' reproduction.

Are human‐altered landscapes reshaping carnivore niche spaces in the Trans‐Himalaya?

Wildlife Biology, EarlyView.
Understanding carnivore interactions under growing human pressures is crucial for conservation. We examined spatial and temporal niche structuring among snow leopards Panthera uncia, Himalayan wolves Canis lupus chanco, and red foxes Vulpes vulpes; while also incorporating free‐ranging dogs Canis lupus familiaris as a human‐subsidized mesopredator ...

Relación Entre el Índice de Área Foliar y el Índice Normalizado de Vegetación en el Bosque Húmedo Tropical de Panamá en Gamboa

Revista de I + D Tecnológico, 2014
El índice de área foliar (LAI) es una variable útil para describir la productividad y dinámica de los ecosistemas forestales además de un indicador de la salud y desarrollo del dosel. Se han realizado pocos estudios de esta variable en regiones de bosque

Analysis of the intensity of erosive processes and state of vegetation cover in the zone of influence of the Kolubara Mining Basin

Open Geosciences
Ensuring the quality protection of geospatial elements entails environmental control, a task unattainable without precise measurement results. This article aims to conduct a spatio-temporal analysis of soil degradation and vegetation status within the ...

Delineating seasonal shifts in reindeer habitat and diet selection by integrating GPS telemetry and stable isotope analysis

Wildlife Biology, EarlyView.
Seasonal changes shape herbivore behaviour by altering forage availability and habitat conditions; however, few studies integrate diet and habitat selection data across temporal scales. This study uses seasonality as a unifying framework to combine fine‐scale GPS‐based habitat selection data with broader‐scale dietary information from stable isotope ...
