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 ...

To quantify the interaction between anthropogenic activities and atmospheric environment in North China, spatiotemporal characteristics, transmission, source apportionment a health risk assessment of elements were analyzed regional background research stations during period 2017. This study found that concentration PM2.5 16 station was 1.5 2.8 times higher, respectively, than station. Under com...

Human activities are responsible for the translocation of vast amounts of organisms, altering natural patterns of dispersal and gene flow. Most research to date has focused on the consequences of anthropogenic transportation of non-indigenous species within introduced ranges, with little research focusing on native species. Here, we compared genetic patterns of the sessile marine invertebrate, ...

The present study represents a first insight into the Draa Lasfar min (Marrakech - Morocco) to assess the degree of polymetallic pollution caused by anthropogenic activities (like mine extraction) and consequently the possible diffusion of heavy metals and to predict the risk of their mobility in the surroundings of the mine area. The edaphologic parameters pH and electrical conductivity (EC) w...

[1] The global tropospheric budget of gaseous and particulate non-methane organic matter (OM) is re-examined to provide a holistic view of the role that OM plays in transporting the essential nutrients nitrogen and phosphorus to the ocean. A global 3-dimensional chemistry-transport model was used to construct the first global picture of atmospheric transport and deposition of the organic nitrog...
