Negev shrew Negev shrew The Negev shrew ("Crocidura ramona"), also known as the Ramon's shrew (, "") is a species of mammal in the family Soricidae. So far, it is only known from Israel. It is found in three regions: Mizpe Ramon and Sede Boqer in the Negev Desert, and Sartaber at the northern edge of the Judean Desert. It is likely that the species occurs more widely in the region than currently known (i.e., in Jordan, where similar habitats and Crocidura species have not been well surveyed). The three locations in which the species occur are rocky desert areas at altitudes
Mojave Desert needed for survival in the flora of the Sonoran Desert, which has an overlap in its major flora, such as the creosote bush ("Larrea tridentata"). The soil types in the Mojave and Sonoran deserts are mostly derived from volcano, specifically the areas in California. As the topography goes down, particle sizes decreases as you move down the gradient, where you can also find low alkalinity. These erosional gradient is a habitat for many plant communities. As you go up the gradient of the desert, you will find more pediment and alluvial fan soil. In this areas, the flora is mostly
