Scale dependence of species–area relationships is widespread but generally weak in Palaearctic grasslands
( Wiley , 2021 , Article)Questions: Species–area relationships (SARs) are fundamental for understanding biodiversity patterns and are generally well described by a power law with a constant exponent z. However, z-values sometimes vary across spatial ... -
Scale effects on the relationships between land characteristics and ecosystem services- a case study in Taihu Lake Basin, China
( Elsevier , 2020 , Article)© 2020 Elsevier B.V. It is generally recognized that marginal changes in landscape characteristics can influence multiple ecosystem services, but the causal relationships involved are still very unclear due to lack of ... -
Screening Of Some Qatari Plant Extracts For Anti Fungal Activities Of Plant Pathogenic Fungi
( Hamad bin Khalifa University Press (HBKU Press) , 2014 , Conference Paper)The present study aimed to evaluate the antifungal activity of three desert plants extracts grown naturally in Qatar: (Al-rayhan) Ocimum basilicum, Shafallah (Capparis spinosa) and Qwaif(Prosopis juliflora)to study their ... -
Seed priming alleviates salt stress in two fenugreek (Trigonella foenum-graecum l.) Cultivars
( United Arab Emirates University , 2022 , Article)Salinity is globally considered a widespread problem of the irrigated soils in arid and semi-arid areas. To minimize the negative effect of salinity seed priming technique is proved as a useful by improve germination and ... -
Seismic detection and characterization of a man-made karst analog - A feasibility study
( Society of Exploration Geophysicists , 2021 , Article)At the site of a water drainage shaft on the campus of Qatar University that serves as a man-made karst analog, two seismic imaging techniques were adapted to use resonant scattered waves recorded during active-source ... -
Seismic detection of a sinkhole using spectral-based analysis
( Society of Exploration Geophysicists , 2014 , Conference Paper)Seismic data recorded during a survey in the vicinity of a sinkhole revealed distinct resonances at 70 Hz. Frequency domain data inversion based on exact modeling produced effective elastic parameters for the location over ... -
Sentinel-2 image transformation methods for mapping oil spill – A case study with Wakashio oil spill in the Indian Ocean, off Mauritius
( Elsevier B.V. , 2021 , Article)Although several indices have been constructed and available at the Index database (IDB) for Sentinel-2 satellite to map and study several earth resources, no indices have been developed to map oil spill. We constructed ... -
Severe vegetation degradation associated with different disturbance types in a poorly managed urban recreation destination in Iran
( Springer Nature , 2021 , Article)Recreational activities worldwide have major impacts on the environment. This study examined the impact of different kinds of recreational activities on plant communities in a highly visited park in Mashhad, Iran. Vegetation ... -
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 ... -
