global climate change and infectious diseases
climate change is occurring as a result of warming of the earth’s atmosphere due to human activity generating excess amounts of greenhouse gases. because of its potential impact on the hydrologic cycle and severe weather events, climate change is expected to have an enormous effect on human health, including on the burden and distribution of many infectious diseases. the infectious diseases tha...
متن کاملGlobal Change Ecology
Atmospheric CO2 and O3 concentrations are increasing due to human activity and both trace gases have the potential to alter C cycling in forest ecosystems. Because soil microorganisms depend on plant litter as a source of energy for metabolism, changes in the amount or the biochemistry of plant litter produced under elevated CO2 and O3 could alter microbial community function and composition. P...

Wetlands evapotranspire more water than other ecosystems, including agricultural, forest and grassland ecosystems. However, the effects of elevated atmospheric carbon dioxide (C02) concentration (Ca) on wetland evapotranspiration (ET) are largely unknown. Here, we present data on 12 years of measurements of ET, net ecosystem C02 exchange (NEE), and ecosystem water use efficiency (EWUE, i.e. NEE...
