Oxisols are a soil order in USDA soil taxonomy, best known for their occurrence in tropical rain forest within 25 degrees north and south of the Equator. In the World Reference Base for Soil Resources (WRB), [1] they belong mainly to the ferralsols, but some are plinthosols or nitisols. Some oxisols have been previously classified as laterite ...

The structure of a tropical rainforest is stratified into layers, each hosting unique ecosystems. These include the emergent layer with towering trees, the densely populated canopy layer, the understory layer rich in wildlife, and the forest floor, which is sparse due to low light penetration. The soil is characteristically nutrient-poor and ...
For comparison, a tropical rainforest biome may contain thousands of tree species, but this is not to say mangrove forests lack diversity. Though the trees are few in species, the ecosystem that these trees create provides a habitat for a great variety of other species, including as many as 174 species of marine megafauna .
The Globe and Mail is a Canadian newspaper printed in five cities in western and central Canada.With a weekly readership of more than 6 million in 2024, it is Canada's most widely read newspaper on weekdays and Saturdays, [2] although it falls slightly behind the Toronto Star in overall weekly circulation because the Star publishes a Sunday edition, whereas the Globe does not.
There are several reasons for the poor soil quality. First is that the soil is highly acidic. The roots of plants rely on an acidity difference between the roots and the soil in order to absorb nutrients. When the soil is acidic, there is little difference, and therefore little absorption of nutrients from the soil. Second, the type of clay ...
Temperate coniferous forests sustain the highest levels of biomass in any terrestrial ecosystem and are notable for trees of massive proportions in temperate rainforest regions. [ 1 ] Structurally, these forests are rather simple, consisting of 2 layers generally: an overstory and understory .
The Neotropic includes more tropical rainforest (tropical and subtropical moist broadleaf forests) than any other realm, extending from southern Mexico through Central America and northern South America to southern Brazil, including the vast Amazon rainforest. These rainforest ecoregions are one of the most important reserves of biodiversity on ...
