The eggs are deposited into the mound, and the sun's heat, the warm environment, and the natural decay of vegetation maintain a warm temperature that aids the development of the embryo.
Among the major players in producing CO2 were biological processes on land, such as animal respiration; soil chemistry; the death and decay of vegetation; the release of CO2 from the oceans, triggered in part by the growth of coral reefs; and the burning of forests and plains, either by wildfires or by people clearing land for agriculture.
The organic soils, formed from the decay of lush vegetation, range from discontinuous shallow patches to accumulations of peat and muck 8 to 10 feet (2.4 to 3 metres) thick near Lake Okeechobee.
A heap of grasses and other vegetation is covered in soil to form a mound that measures approximately 3 feet (1 metre) in diameter by 3 feet in height; fertile soil is produced by the decay of the vegetation within the mound, which is later flattened and the enriched soil spread among important crops.
Frazer writes, "The object of the poem is to explain the origin of the Eleusinian mysteries" — a September harvest ritual about "the decay and revival of vegetation".
Decay of the dead vegetation quickly uses up what oxygen is supplied, so that the mud and bottom waters are low or lacking in oxygen content.
The reactivation of linear erosion would seem, therefore, to be a consequence of the decay of this permanent vegetation, induced by an increase in the duration or severity of drought periods, which meant that the water storage capacity of the valley fillings was insufficient to support it.
I recall the lacustrine smell of decaying vegetation, the crackle of dry stems underfoot, the sounds of water flowing beyond a wall of stems, plumed flower heads of reeds swaying like banners high overhead.
Moreover, for large values of the hydric stress, we predict an opposing route to the formation of periodic patterns, where a homogeneous cover of vegetation may decay to spot-like patterns.
Some members of the genus Megapodius (including jungle-dwelling members of M. freycinet) build mounds of decaying vegetation up to 10 metres (33 feet) long and 5 metres (16 feet) high.
It has been isolated from many substrates, including a wide variety of soils, decaying vegetation, fruit, vegetables, seeds and dung [ 10].
