Despite of a high abundance antibiotics, heavy metals, and organic matters detected in the Saigon River Ho Chi Minh City, level spread antibiotic resistance genes this river are poorly understood. In study, total 10 (ARGs), including conferring to aminoglycosides (aac(6)-Ib-cr), β-lactam antibiotics (blaCTX-M, blaSHV, blaTEM), quinolones (qnrA, qnrB), sulfonamides (sul1, sul2), trimethoprim (df...
Vegetation cover plays a key role in terrestrial ecosystem; therefore, it is important for researchers to investigate the variation and influencing factors of vegetation cover. China has experienced large-scale change recent years. We summarized literature revealed how anthropogenic activities influence China. Afforestation intensification cropland played greening. Urbanization showed “U” shape...
Marine isonitriles represent the largest group of natural products carrying the remarkable isocyanide moiety. Together with marine isothiocyanates and formamides, which originate from the same biosynthetic pathways, they offer diverse biological activities and in spite of their exotic nature they may constitute potential lead structures for pharmaceutical development. Among other biological act...
Background: It has been claimed that the turndown of insect population due to strengthening agriculture may have led a reduction in number farmland birds some autecological studies support this postulate. Insect abundance is significantly associated with bird density measures large scale invertebrate sampling was done using suction traps and results showed time as food quality quantity changes ...
Abstract Land-use change remains the main threat to tropical forests and their dependent fauna flora, degradation of existing forest remnants will further accelerate species loss. Forest may result directly from human use or through spatial effects land-use change. Understanding drivers its on biodiversity is pivotal for formulating impactful management monitoring protocols, but such knowledge ...
