Responses of lichen communities to 18 years of natural and experimental warming
( Oxford University Press , 2017 , Article)Background and Aims Climate change is expected to have major impacts on high alpine and arctic ecosystems in the future, but empirical data on the impact of long-term warming on lichen diversity and richness are sparse. ... -
Resveratrol-mediated regulation of mitochondria biogenesis-associated pathways in neurodegenerative diseases: molecular insights and potential therapeutic applications.
( Bentham Science Publisher , 2022 , Article Review)Neurodegenerative disorders include neurological conditions that affect nerve cells, causing the progressive loss of their functions and ultimately leading to loss of mobility, coordination, and mental functioning. The ... -
Reuse of Sludge as Organic Soil Amendment: Insights into the Current Situation and Potential Challenges
( MDPI , 2023 , Article Review)Sludge generation as an organic by-product of wastewater treatment has seen a consistent increase worldwide due to population growth and industrial activities. This poses a chronic challenge regarding management options ... -
Revealing the maternal demographic history of Panthera leo using ancient DNA and a spatially explicit genealogical analysis
( BioMed Central Ltd. , 2014 , Article)Background: Understanding the demographic history of a population is critical to conservation and to our broader understanding of evolutionary processes. For many tropical large mammals, however, this aim is confounded by ... -
Reverse osmosis membrane fouling and its physical, chemical, and biological characterization
( Elsevier , 2022 , Book chapter)Membrane fouling is caused by microorganisms and organic, inorganic, and colloidal substances that are present in the feedwater. It affects the performance of membranes in water treatment systems in terms of increase in ... -
Review of Progress and Prospects in Research on Enzymatic and Non- Enzymatic Biofuel Cells; Specific Emphasis on 2D Nanomaterials
