During winter, when water lilies have no surface leaves, the gases in the rhizome lacunae approach equilibrium with the gases of the sediment water. The resulting increase of internal pressure is manifested by the sustained streams of bubbles (up to 37 percent methane and 6 percent carbon dioxide) that escape when emerging leaves are torn in the spring. Methane continues to enter the roots and rhizome during summer, rapidly moves up the petioles, and passes out through the emergent leaves into…

The network of internal gas spaces in the yellow water lily constitutes a pressurized flow-through system which forces oxygen to the roots and rhizome buried in the anaerobic sediment. By the purely

Methane efflux from the pelagic regions of four lakes

Methane emission to the atmosphere was studied in the deepest, central (pelagic) regions of one freshwater and three meromictic, alkaline saline lakes. The range of methane emissions was 0.004 to

Biological methanogenesis and the CO2 greenhouse effect

It is well established that plants tend to increase net photosynthesis under increased carbon dioxide. It is also well established that a large fraction of atmospheric methane is produced by

VENTILATION BY FLOATING LEAVES IN NUPHAR

The ventilation system operating in two different subspecies of N. luteum growing in Alaska and in Massachusetts is found, finding that during certain times of the year the leaves are warmed not only by the sun in daylight but also by lake water at night, allowing the ventilation to continue during darkness.

Biological Formation and Consumption of Methane

This chapter describes the conditions that leading to biogenic methane formation in natural environments, the metabolic pathways and interactions that lead to methanogenesis, and the implications of these factors on the biogeochemistry of methane.

Physiological Ecology of Methanogens

Biological methanogenesis plays a major role in the carbon cycle on Earth. Methanogenesis is the terminal step in carbon flow in many anaerobic habitats, including marine and freshwater sediments,

Carbon Gas Fluxes in Re-Established Wetlands on Organic Soils Differ Relative to Plant Community and Hydrology

We measured CO2 and CH4 fluxes for 6 years following permanent flooding of an agriculturally managed organic soil at two water depths (~25 and ~55 cm standing water) in the Sacramento–San Joaquin

Tracer studies of gas circulation in Nuphar: 18O2 and 14CO2 transport

A flow-through ventilation system operates in the yellow waterlily (Nuphar luteum ssp. macrophylla Beal). The flow of air into the youngest emergent leaves and down their petioles to the rhizome is

Methane emission to the atmosphere through emergent cattail ( Typha latifolia L.) plants

A large quantity of methane (CH4) is produced microbially in sediments of marshes by flowing through and out of emergent aquatic plants and its emission to the atmosphere is emitted by these plants.
