Mammals have dominated Earth for approximately 55 Myr thanks to their adaptations and resilience to warming and cooling during the Cenozoic. All life will eventually perish in a runaway greenhouse once absorbed solar radiation exceeds the emission of thermal radiation in several billions of years. ...
Second is an analytical megabias, strongly favoring the discovery and collection of the wetland biome from Pennsylvanian strata, overlooking the less frequently and more poorly preserved drought-tolerant biome. By Permian times, vast wetlands, and their fossil record, had largely disappeared from ...
As estimated in the Global Review of Wetland Resources and Priorities for Wetland Inventory (Finlayson and Davidson, 1999), wetlands cover more than 1,280 million ha, representing less than 3% of the total biome area of the Biosphere. However, because of the overall high specific richness, ...
Taiga, biome composed mainly of cone-bearing needle-leaved or scale-leaved evergreen trees, found in northern circumpolar regions typified by long winters and moderate to high annual precipitation. Taiga, ‘land of the little sticks’ in Russian, is name
Within the broad habitats, we observed several deviations from the general climate-traits relationships observed across habitats. Along the Mediterranean gradient, community plant height decreased in forest and coastal habitats; SLA increased in wetlands and SRL decreased in coastal saltmarshes, forests, ...

The core of the work is a quantitative, dynamic model describing the coexistence of different Mediterranean tree species, typical of arid or semi-arid wetlands. Two kind of species, i.e. Hygrophilous (drought sensitive, flood resistant) and Non-hygrophilous (drought resistant, flood sensitive),...
31.4). Principal agricultural activities leading to GHG emissions are plowing, drainage of wetlands, enteric fermentation, fertilizer use, manure management, and fuel consumption [24]. Averaged over 2001–10 period, agriculture, forestry, and other land use contributed the following [25]: (1) 1.36...
How are wetlands and ecosystem services connected? How does desertification impact the Earth's climate system? How does afforestation affect the carbon cycle? How does climate change affect ecosystem services? How do the plants in a rainforest contribute to the water cycle?
Natural capital is part of society’s productive base, producing flows of market and non-market benefits. Following Dasgupta52, the total natural capital stock at timetcan be written as the sum of the quantity of individual natural assets (soils, forests, wetlands etc.) multiplied by their sha...
