The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. [1]
Around the world, characteristic plants of these habitats display features such as rosette structures, waxy surfaces, and abundant pilosity. [1] The páramos of the northern Andes are the most extensive examples of this habitat type. Although ecoregion biotas are most diverse in the Andes, these ecosystems are distinctive wherever they occur in ...
The Greater Yellowstone Ecosystem (GYE) is one of the last remaining large, nearly intact ecosystems in the northern temperate zone of Earth. [1] It is located within the northern Rocky Mountains , in areas of northwestern Wyoming , southwestern Montana , and eastern Idaho , and is about 22 million acres (89,000 km 2 ). [ 2 ]
The following is a list of ecoregions in the United States as identified by the World Wide Fund for Nature (WWF). The United States is a megadiverse country with a high level of endemism across a wide variety of ecosystems.
The world-average ecological footprint in 2016 was 2.75 global hectares per person (22.6 billion in total). With a world-average biocapacity of 1.63 global hectares (gha) per person (12.2 billion in total), this leads to a global ecological deficit of 1.1 global hectares per person (10.4 billion in total).
