The black and white snapper has a wide Indo-Pacific range. It occurs along the eastern coastline of Africa from the Red Sea south as far as South Africa, the Seychelles, islands in the Mozambique Channel, Madagascar and western Mascarenes, east to the Maldives, Laccadives, the Chagos Islands, Cocos (Keeling) Islands and Christmas Island and Sri Lanka.
The salinity levels in brackish marshes can range from 0.5 ppt to 35 ppt. [2] Marshes are also characterised by low-growing vegetation and bare mud or sand flats. [3] Due to the variations in salinity, brackish marshes create a distinctive ecosystem where plants from either freshwater or saltwater marshes can co-inhabit. [4]
African savannas occur between forest or woodland regions and grassland regions. Flora includes acacia and baobab trees, grass, and low shrubs. Acacia trees lose their leaves in the dry season to conserve moisture, while the baobab stores water in its trunk for the dry season. Many of these savannas are in Africa.
Seagrasses are flowering plants with stems and long green, grass-like leaves. They produce seeds and pollen and have roots and rhizomes which anchor them in seafloor sand. Seagrasses form dense underwater meadows which are among the most productive ecosystems in the world.
This border vista is a 20-foot-wide (6.1 m) man-made cut-through of forestland maintained along areas of the border with dense forestation. There are many different sections of the vista, and the total length can vary depending on cycles of maintenance and upkeep, but an approximate length of 1,349 miles (2,171 km) has been reported by the United States Department of Homeland Security (DHS).
The appearance of mountains in the western United States during the Miocene and Pliocene epochs, a period of some 25 million years, created a continental climate favourable to the evolution of grasslands. [10] Around 5 million years ago during the Late Miocene in the New World and the Pliocene in the Old World, the first true grasslands ...
White surfaces reflect more than half of the radiation that reaches them, while black surfaces absorb almost all. White or white coated roofing membranes, or white gravel cover would appear to be the best approach to control these problems where membranes must be left exposed to solar radiation.
Similarly, the Caribbean coast, eastward from the Gulf of Urabá on the Colombia – Panamá border to the Orinoco river delta, on the Atlantic Ocean (ca. 4,000 km (2,485 mi)), have long dry periods (the extreme is the BSh climate (see below), characterized by very low, unreliable precipitation, present, for instance, in extensive areas in the ...
