Referring to an animal that lives in trees; tree-climbing. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria. Vegetation is typically sparse, though spectacular blooms may occur following rain.
Deserts can be cold or warm and daily temperates typically fluctuate. In dune areas vegetation is also sparse and conditions are dry. This is because sand does not hold water well so little is available to plants.
In dunes near seas and oceans this is compounded by the influence of salt in the air and soil. Salt limits the ability of plants to take up water through their roots. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a now extinct synapsid ancestor; the fossil record does not distinguish these possibilities.
Convergent in birds. Iteroparous animals must, by definition, survive over multiple seasons or periodic condition changes. Epiphytes and climbing plants are also abundant. Precipitation is typically not limiting, but may be somewhat seasonal. Savannas are grasslands with scattered individual trees that do not form a closed canopy.
Extensive savannas are found in parts of subtropical and tropical Africa and South America, and in Australia.
See also Tropical savanna and grassland biome. Vegetation is made up mostly of grasses, the height and species diversity of which depend largely on the amount of moisture available. Fire and grazing are important in the long-term maintenance of grasslands. Center for Biological Diversity.
