Plastic pollution poses a significant threat to ecosystem health worldwide. This study examines the determinants of environmental changes in human-modified ecosystems through a quantitative-qualitative system dynamics modeling approach: field experiments conducted on a 310 m² unsaturated clay-rich bed and a 2.5 m² clay-rich shore of a plastic-impac...

Global urbanization has resulted in local habitat fragmentation, influencing ecological processes and biodiversity conservation. However, little is known about the diversity and distribution of microbial communities across urban biotopes. Here, we compared testate amoeba communities in Moscow (63 samples from five urban parks) and Xiamen (69 sample...

Understanding the extent of human activities leading to an influx of chemical pollutants that cause substantial environmental transformations is the focus of much ongoing research. In this study, we present a multi-proxy record based on a sediment core from a large subtropical reservoir (Xinfengjiang Reservoir) in south China with an emphasis on th...

Investigation of bacterial community dynamics across different time scales is important for understanding how environmental conditions drive community change over time. Bacterioplankton from the surface waters of a subtropical urban reservoir in southeast China were analyzed through high-frequency sampling over 13 months to compare patterns and eco...

Difflugia australis, first described by Playfair (1918), has a unique morphotype. However, in the absence of morphometric data, it has not yet been reliably classified within the largest testate amoeba genus Difflugia. In this study D. australis collected from a subtropical reservoir in southeast China was investigated by means of light and scannin...

Conditionally rare bacteria are ubiquitous and perhaps the most diverse of microbial lifeforms, but their temporal dynamics remain largely unknown. High-throughput and deep sequencing of the 16S rRNA gene has allowed us to identify and compare the conditionally rare taxa with other bacterioplankton subcommunities. In this study, we examined the eff...

Deep high-altitude mountain lakes can act as a natural laboratory, and have the potential to contribute ecological data for understanding the way natural climate and anthropogenic changes that can affect the ecosystems. We present a multi-proxy record from a sediment core from such a lake (Lake Lugu) in southwest China with emphasis on the changes...

Textural analysis carried out for the sediments of the Nayakkankuppam coast revealed that inlet part is dominated by fine sand, central part is dominated by medium sand and outlet part is dominated by coarse sand. The grain size parameters namely Mean size (MZ), standard deviation (σ1), skewness(Ski), and kurtosis (KG) of percentile values derived...

Currently it is estimated that the handicraft industry earns Rwanda between 3 and 4 million US Dollars annually, with the potential to raise over 7 million US Dollars annually in its export earnings to complement the coffee, tea and mineral exports that have been dominating Rwanda’s export receipts as reported in the East African new paper of 6th J...

The race of the country in economic development involves an essential infrastructure and protected environment to ensure people and workplace healthy and safe respectively. The growth of this programme must go hand in hand with preliminary studies to harmonize these two elements, followed by executions and regular technical adjustments to prevent d...
