The terrestrial ecoregions of Mexico span two biogeographic realms - the Nearctic and Neotropic - which together constitute the entire biogeography of the Americas. Veracruz is the most biodiverse state with 10 ecoregions across 5 biomes and 2 realms. Chiapas comes in a close second with 10 ecoregions across 4 biomes in the same realm.
Mexico ranks fourth [1] in the world in biodiversity and is one of the 17 megadiverse countries. With over 200,000 different species, Mexico is home of 10–12% of the world's biodiversity. [ 2 ] Mexico ranks first in biodiversity in reptiles with 707 known species, second in mammals with 438 species , fourth in amphibians with 290 species, and ...
The Mesoamerican Biological Corridor (MBC) is a region that consists of Belize, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, Panama, and some southern states of Mexico. The area acts as a natural land bridge from South America to North America, which is important for species who use the bridge in migration. Due to the extensive ...
The Tropical Wet Forests ecoregion in North America includes the southern tip of the Florida Peninsula in the United States; within Mexico, the Gulf Coastal Plain, the western and southern part of the Pacific Coastal Plain, most of the Yucatán Peninsula and the lowlands of the Chiapas Sierra Madre, which continue south to Central and South ...
Central America connects North America to South America. The land bridge was completed 2.8 million years ago, when the Isthmus of Panama was formed, linking the two continents for the first time in tens of millions of years. The resulting Great American Interchange of animals and plants shaped the flora and fauna of the Central America ...
According to a study, there are over 50 plants that are dependent on bee pollination, many of these being key staples to feeding the world. [12] Another study conducted states that a lack of plant diversity will lead to a decline in the bee population fitness, and a low bee colony fitness has impacts on the fitness of plant ecosystem diversity ...
Conservation International identified 17 megadiverse countries in 1998, [1] [2] all of which are located at least partially in tropical or subtropical regions. Megadiversity means exhibiting great biodiversity. The main criterion for megadiverse countries is endemism at the level of species, genera and families. A megadiverse country must have ...
Types of biodiversity include taxonomic or species, ecological, morphological, and genetic diversity. Taxonomic diversity, that is the number of species, genera, family is the most commonly assessed type. [7] A few studies have attempted to quantitatively clarify the relationship between different types of diversity.
