Mapping biodiversity conservation priorities for protected areas: A case study in Xishuangbanna Tropical Area, China
( Elsevier , 2020 , Article)Global biodiversity is declining rapidly, posing a severe threat to ecosystem functions and services. Protected Areas (PAs) can be extremely effective in protecting biodiversity, but conservation gaps arise as a result of ... -
Braking effect of climate and topography on global change-induced upslope forest expansion
( Springer New York LLC , 2017 , Article)Forests are expected to expand into alpine areas due to global climate change. It has recently been shown that temperature alone cannot realistically explain this process and that upslope tree advance in a warmer scenario ... -
Impacts of twenty years of experimental warming on soil carbon, nitrogen, moisture and soil mites across alpine/subarctic tundra communities
( Nature Publishing Group , 2017 , Article)High-altitude and alpine areas are predicted to experience rapid and substantial increases in future temperature, which may have serious impacts on soil carbon, nutrient and soil fauna. Here we report the impact of 20 years ... -
RNA:DNA ratios as a proxy of egg production rates of Acartia
( Academic Press , 2017 , Article)Estimates of copepod secondary production are of great importance to infer the global organic matter fluxes in aquatic ecosystems and species-specific responses of zooplankton to hydrologic variability. However, there is ... -
Impact assessment of non-indigenous jellyfish species on the estuarine community dynamic: A model of medusa phase
( Academic Press , 2017 , Article)Non-indigenous jellyfish species (NIJS) Blackforida virginica have recently been introduced to the Guadiana Estuary. A modelling approach was used for the assessment of the species-specific impact on the native community, ... -
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 ... -
Modulation of Plant Defense System in Response to Microbial Interactions
( Frontiers Media , 2020 , Article)© Copyright © 2020 Nishad, Ahmed, Rahman and Kareem. At different stages throughout their life cycle, plants often encounter several pathogenic microbes that challenge plant growth and development. The sophisticated innate ... -
Environmental impact of utilization of “produced water” from oil and gas operations in turfgrass systems
( Nature Research , 2020 , Article)© 2020, The Author(s). This study attempted to use produced water (PW) to irrigate turfgrass species, Cynodon dactylon and Paspalum sp. Assessment on established grasses, heavy metal accumulation and germination tests for ... -
Improved ecological monitoring for urban ecosystem protection in China
( Elsevier , 2021 , Article)Ecological monitoring (EM) is a significant scientific topic recognized for its potential for providing basic, but vital, data for ecosystem assessment to address sustainability issues. However, a monitoring framework that ... -
Vegetative insecticidal protein of Bacillus thuringiensis BLB459 and its efficiency against Lepidoptera
( Elsevier Ltd , 2017 , Article)Bacillus thuringiensis strain BLB459 supernatant showed a promising activity against Lepidopteran pests with extremely damages in the larvae midgut. Investigations of the genes that encode secreted toxin demonstrated that ... -
Rural development program in tribal region: A protocol for adaptation and addressing climate change vulnerability
( Elsevier Ltd , 2017 , Article)Tribal peoples globally are among the most vulnerable groups to climate change and variability. This is due to a combination of their relative poverty and their dependence on agriculture and natural support systems (NSS). ... -
Combinatorial effect of mutagenesis and medium component optimization on Bacillus amyloliquefaciens antifungal activity and efficacy in eradicating Botrytis cinerea
( Elsevier GmbH , 2017 , Article)This work is directed towards Bacillus amyloliquefaciens strain BLB371 metabolite production for biocontrol of fungal phytopathogens. In order to maximise antifungal metabolite production by this strain, two approaches ... -
Quantification of Melamine in Milk and Dairy Products by Liquid Chromatography after a Simple Sample Clean-Up Procedure
( Blackwell Publishing Ltd , 2017 , Article)In this work, a simple procedure of melamine determination in dairy products is reported. This is based first on melamine extraction from dairy products by 1% acetic acid, sonication, centrifugation and filtration by 0.45 µm ... -
Estimating carbon dynamics in an intact lowland mixed dipterocarp forest using a forest carbon model
( MDPI AG , 2017 , Article)Intact dipterocarp forests in Asia act as crucial carbon (C) reservoirs, and it is therefore important to investigate the C dynamics in these forests. We estimated C dynamics, together with net ecosystem production (NEP), ... -
