The fennec fox's large ears help keep it cool: when the blood vessels dilate, blood from the body cycles in and dissipates over the expanded surface area. [1]A xerocole (from Greek xēros / ˈ z ɪ r oʊ s / 'dry' and Latin col(ere) 'to inhabit'), [2] [3] [4] is a general term referring to any animal that is adapted to live in a desert.
Many animals obtain energy by eating the surrounding vegetation, however, desert plants are much more difficult for organisms to consume. [10] To avoid intense temperatures, the majority of small desert mammals are nocturnal, living in burrows to avoid the intense desert sun during the daytime.
This is the area with the highest level of plant endemism in Madagascar, with 48% of the genera and 95% of the species endemic. [2] Many constituent plants show extreme adaptations to drought. Spiny plants of the endemic subfamily Didiereoideae form a conspicuous component, especially towards the east.
Increasingly frequent and severe heat waves in the Southwest are damaging some desert plants known for thriving in harsh conditions. Saguaro cacti and agave have both suffered in sweltering ...
The Rub' al Khali desert has very little plant diversity, with about 37 species of flowering plant having been recorded here, 17 of which are only found around the periphery of the desert. There are virtually no trees, and the plants are adapted for desert life and include dwarf shrubs such as Calligonum crinitum and saltbush , and several ...
A xerophyte (from Ancient Greek ξηρός (xērós) 'dry' and φυτόν (phutón) 'plant') is a species of plant that has adaptations to survive in an environment with little liquid water. Examples of xerophytes include cacti, pineapple and some gymnosperm plants.
Plant fruit: the fleshy nutritious part of plants that animal dispense by eating independently came about in flowering plants and in some gymnosperms like: ginkgo and cycads. [239] Water transport systems, like vascular plant systems, with water conducting vessels, independently came about in horsetails, club mosses, ferns, and gymnosperms. [240]
It is a dioecious, leafless, phreatophyte (meaning its roots penetrate deep down to water near the water table) that is found in sandy deserts but not stony plains, in areas with access to ground water such as ephemeral rivers and paleochannels, where sand accumulating in the shelter of its stems can form hummocks up to 1000–1500 m 2 in area and 4 meters in height.
