  Investigation of the ecological characteristics of wildlife species and determination of habitat suitability for them is one of the main pillars for wildlife management and protection. In this study, the winter and spring habitat suitability of black woodpecker (Dryocopusmartius) was studied in ShastKalateh forest. Habitat characteristics, including forest vegetationtype, structural character...

Introduction: More than 168 countries face the phenomenon of land degradation and desertification. Land use changing and more exploitation of nature's potential in arid and semiarid ecosystems over the past three decades have increased the trend of desertification phenomena in these ecosystems. Deserts are dynamic ecosystems that are constantly evolving. Deserts are dynamic ecosystems that are ...

Root to shoot ratio (RS) is commonly used to describe the biomass allocation between below- and aboveground parts of plants. Determining the key factors influencing RS and interpreting the relationship between RS and environmental factors is important for biological and ecological research. In this study, we compiled 2088 pairs of root and shoot biomass data across China's terrestrial biomes to...

Constructed wetlands have gained much importance for treating domestic, industrial and agricultural wastes and are considered as an effective secondary or tertiary treatment method. The main characteristics affect the removal efficiency of constructed wetland are the vegetation type, hydraulic residence time and substrate. The aim of the present study is to examine effect of vegetation type on ...

Combining flux tower measurements with remote sensing or land surface models is generally regarded as an efficient method to scale up flux data from site to region. However, due to the heterogeneous nature of the vegetated land surface, the changing flux source areas and the mismatching between ground source areas and remote sensing grids, direct use of in-situ flux measurements can lead to maj...

recognition of habitats and conditions of species presences in differentsituations can be effective in proper utilization of vegetation. little is known about thevegetation composition of boralan mountain region located in north west of iran in theborder of turkey and azerbaijan with the altitude range of 800-2000m. the aim of thisstudy therefore was to investigate the floristic composition qua...

Recognition is growing that besides ungulates, small vertebrate and invertebrate herbivores are important drivers of grassland functioning. Even though soil microarthropods play key roles in several soil processes, effects of herbivores-especially those of smaller body size-on their communities are not well understood. Therefore, we progressively excluded large, medium and small vertebrate and ...
