Productivity, carbon sequestration and species diversity in virgin and secondary meadow steppes of the Bashkir Cis-Urals [PDF]

Scientific Reports
Steppes are of great importance for the global biogeochemical cycle and are characterized by high economic value. Carbon stocks in the soil of flat steppe landscapes are about one-fourth of the total carbon deposited in global soils.

An Assessment on Bat Diversity in Curitiba, Paraná State, Subtropical Brazil

Brazilian Archives of Biology and Technology, 2021
Urbanization changes natural environments making them inhospitable to autochthonous fauna. However, studies have shown that certain groups and animal species tolerate urban habitat or even benefit from it as is the case of some bats.
