No special status Other Comments Gazella dorcas individuals can go their entire lives without drinking water. They can get all the water they need from the plants they eat. There is a high mortality rate among young born in captivity because of inadequate resistance to infection. Yom-Tov, et al. Glossary living in sub-Saharan Africa south of 30 degrees north and Madagascar.
Palearctic living in the northern part of the Old World. In otherwords, Europe and Asia and northern Africa. 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.
