Socio-ecological vulnerability and resilience of mountain communities residing in capital-constrained environments
( Springer , 2021 , Article)The study evaluated perceived reactions and counter-actions of Himalayan communities to climate change. The evaluation was conducted through identification and characterization of 62 socio-environment-specific indicators ... -
SoilTemp: A global database of near-surface temperature
( wiley , 2020 , Report)© 2020 John Wiley & Sons Ltd Current analyses and predictions of spatially explicit patterns and processes in ecology most often rely on climate data interpolated from standardized weather stations. This interpolated ... -
Source rock evaluation and petroleum generation of the Lower Cretaceous Yamama Formation: Its ability to contribute to generating and expelling petroleum to cretaceous reservoirs of the Mesopotamian Basin, Iraq
( Elsevier , 2022 , Article)The Yamama Formation is an important reservoir as well as a good source rocks in many of the oilfields of the southern Mesopotamian Basin, Iraq. The formation represents a regressive cycle deposited in a shallow carbonate ... -
Spatial heterogeneity analysis of matching degree between endangered plant diversity and ecosystem services in Xishuangbanna
( Springer , 2023 , Article)Biodiversity and ecosystem services (ESs) are closely linked. Human activities have caused critical damage to the habitat and ecosystem function of organisms, leading to decline in global biodiversity and ecosystem services. ... -
Spatial-temporal pattern of cultivated land productivity based on net primary productivity and analysis of influencing factors in the Songhua River basin
( Wiley , 2022 , Article)The inefficient utilization of cultivated land puts the productivity of cultivated land in a low development state. The key challenge for the efficient utilization of cultivated land is to clarify how various ... -
Spatio-temporal changes in water-related ecosystem services provision and trade-offs with food production
( Elsevier , 2021 , Article)A key challenge for sustainability is protecting water-related ecosystems and the services (WESs) they provide while enhancing food security. Food production usually drives land use change, which results in ecosystem ... -
Spatio-temporal variation in potential habitats for rare and endangered plants and habitat conservation based on the maximum entropy model
( Elsevier , 2021 , Article)Rare and endangered plants (REPs) act as key indicators for species habitat priorities, and can thus be critical in global biodiversity protection work. Human activities and climate change pose great threats to REPs, so ... -
Stratigraphy and petroleum systems of the Paleozoic (pre-Khuff) succession, Qatar
( Wiley , 2016 , Article)A thickness of more than 1500m of Palaeozoic (pre-Khuff) siliciclastic strata were encountered in three deep wells (Matbakh A, and Dukhan A and B) drilled in the State of Qatar. These sedimentary rocks have no formal ... -
Survey and identification of date palm pathogens and indigenous biocontrol agents
( American Phytopathological Society , 2020 , Article)Fungal diseases are considered a major threat to plant growth and productivity. However, some beneficial fungi growing in the same environment protect plants from various pathogens, either by secreting antifungal metabolites ... -
Synthesis of nanostructured novel ion-imprinted polymer for selective removal of Cu2+ and Sr2+ ions from reverse osmosis concentrated brine
