Above the neritic zone lie the intertidal (or eulittoral) and supralittoral zones; below it the continental slope begins, descending from the continental shelf to the abyssal plain and the pelagic zone. Within the neritic, marine biologists also identify the following: [citation needed] The infralittoral zone is the algal-dominated zone down to ...

The climate and ecology of different locations on the globe naturally separate into life zones, depending on elevation, latitude, and location.The generally strong dependency on elevation is known as altitudinal zonation: the average temperature of a location decreases as the elevation increases.
This page features a list of biogeographic provinces that were developed by Miklos Udvardy in 1975, [1] [2] later modified by other authors. [according to whom?] Biogeographic Province is a biotic subdivision of biogeographic realms subdivided into ecoregions, which are classified based on their biomes or habitat types and, on this page, correspond to the floristic kingdoms of botany.
Ephedra is a genus of gymnosperm shrubs.As of February 2025 there were 77 recognized species. The various species of Ephedra are widespread in many arid regions of the world, ranging across southwestern North America, southern Europe, northern Africa, southwest and central Asia, northern China, and western South America.

Marine botany is the study of flowering vascular plant species and marine algae that live in shallow seawater of the open ocean and the littoral zone, along shorelines of the intertidal zone, coastal wetlands, and low-salinity brackish water of estuaries. It is a branch of marine biology and botany.
