Key message We present a relational database containing compositional and structural characteristics of 575 permanent 100 m 2 shrubland plots distributed in the NE Iberian peninsula. The datasets provide valuable information about fuels to improve fire danger prediction, study vegetation dynamics relation drought or test aerial-based methodologies with ground-based information. Dataset access i...

The study investigates the impact of land use/cover changes on dynamics surface temperature in Abaminus watershed, Northwest Ethiopia. Landsat-5 images 1987, 1999, and 2010, Landsat-8 image 2018 were used as sources data. calculated using a land-use transition matrix. Data generated from household surveys presented percentage values to identify driving forces changes. (LST) result was quantifie...

Potentilla fruticosa , a major alpine shrubland type, is widely distributed across the Tibetan Plateau, and grazing most common disturbance in shrublands of P. . However, soil organic carbon (SOC), total nitrogen (STN), phosphorus (STP), their stoichiometry under different intensities were unclear. In our study, we explored SOC, STN, STP, stoichiometry, controlling factors heavy (HG), moderate ...

Environmental transformations are the results of land-use and land-cover (LULC) changes. This study aims to investigate LULC changes associated factors in Este District northwestern Ethiopia, for last four decades (the 1980s 2020s). The classes were analyzed using supervised classification techniques ERDASS IMAGINE 2015 ArcGIS 10.3.1, categorizing Landsat satellite images 1984, 2000, 2018 into ...

Shrub encroachment, a globally recognized response to climate warming, usually involves late successional species in mountain environments, without alteration climax communities. We show that major ecosystem change is occurring the European Alps across 1000 m elevation gradient, with pioneer hygrophilous Salix shrubs, previously typical of riparian forests, wetlands and avalanche ravines, encro...

Soil microorganisms play an important role in urban green spaces by providing ecological functions. However, information on the structure and assembly of microbial communities public risk pathogenic bacteria remains elusive. Here, we conducted a field survey soil organisms different vegetation cover types (e.g., grasslands, shrublands, woodlands) based 16 S rRNA gene amplicon sequencing. We fou...

Plant species in dryland ecosystems are limited by water availability and may be vulnerable to increases in aridity. Methods are needed to monitor and assess the rate of change in plant abundance and composition in relation to climate, understand the potential for degradation in dryland ecosystems, and forecast future changes in plant species assemblages. I employ nearly a century of vegetation...

This study analyzed spatial and temporal changes in land use/land cover in a typical mountain watershed covering an area of 153 km2 in central Nepal by comparing classified satellite images from 1976, 1989 and 2000 coupled by GIS analyses and also investigated changes in the shape of land use patches over the period. The results show an increase in broadleaf forest, conifer forest and winter-cr...
