The role of wetlands in the carbon cycle

Inter-tidal wetlands, such as mangroves, play an

important role in carbon sequestration.

Wetlands play an important role in landscape function, including cycling of carbon, water and nutrients, food and fibre production, water purification, regulation of flows, provision of habitats, and tourism and recreation services.

The role of wetlands in carbon sequestration and storage has generally been under-estimated. Wetlands cover approximately six to nine per cent of the Earth's surface and contain about 35 per cent of global terrestrial carbon. As wetlands are centres of high productivity in the landscape, they have a high capacity to sequester and store carbon. As depositional areas, wetlands can also store carbon-rich organic sediments. However, under anaerobic conditions, wetlands can also produce greenhouse gases such as methane and nitrous oxide, though this is limited in saline conditions. Clearing or drainage of wetlands can lead to large losses of stored organic carbon to atmospheric carbon dioxide.

Greater consideration needs to be given to the roles of wetlands as carbon sources, sinks and storages when designing climate protection and natural resource programs. Therefore, in consultation with the Wetlands and Waterbirds Taskforce, the Australian Government Department of Sustainability, Environment, Water, Population and Communities has developed an issues paper, The role of wetlands in the carbon cycle. This paper considers the role of wetlands in carbon cycling, the implications of climate change for wetland functions and services, and mechanisms to promote protection and restoration of wetlands for multiple benefits including carbon sequestration.

Explanation:

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
