Aquatic herbivores facilitate the emission of methane from wetlands.

Modeling Methane Emission from Wetlands in North-Eastern New South Wales, Australia Using Landsat ETM+

Natural wetlands constitute a major source of methane emission to the atmosphere, accounting for approximately 32 ± 9.4% of the total methane emission. Estimation of methane emission from wetlands at both local and national scale using process-based models would improve our understanding of their contribution to global methane emission. The aim of the study is to estimate the amount of methane ...

A Semi Automated Empirical Model for Estimation of Ch4 Emission Using Coarse Resolution Thermal Data

Concentration of atmospheric methane is considered to have a significant effect on climate because of its GWP (Global Warming Potential), which is 21 times of CO2. Methane is generated by the process of methanogenesis under wet anaerobic conditions, oxidation by methanotrophic bacteria and transportation to the atmosphere. Wetlands are the major source of methane emission, because of the presen...

Freshwater Wetland Resources and Biology

The term “wetlands” means those areas that are inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support a prevalence of vegetation typically adapted for life in saturated soil conditions. They are located at the ecotones between dry terrestrial ecosystems and permanently wet aquatic ecosystems. As such, they have an intermediate hydrology, a bioch...

Influence of Different Plant Species on Methane Emissions from Soil in a Restored Swiss Wetland

Plants are a major factor influencing methane emissions from wetlands, along with environmental parameters such as water table, temperature, pH, nutrients and soil carbon substrate. We conducted a field experiment to study how different plant species influence methane emissions from a wetland in Switzerland. The top 0.5 m of soil at this site had been removed five years earlier, leaving a subst...
