When you ask the question "Has this author been cited in other resources?" you are evaluating the relevance of the resource. You cite a source in order to get a stronger picture of its intellectual value. And if the author (the source) you cited has been cited in other resources too, this means that the source is reliable (is able to be trusted), you are evaluating the reliability of the source.
There are several reasons why you should cite resources in your works: to proof your thesis, to show proper research and many more.
It is important to note that such animals living in desert conditions do not waste water by sweating to control body temperature. They mostly try burrowing during the day time to avoid getting dehydrated. Their urine is highly concentrated and it is mostly in the form of uric acid. These means help the desert animals to survive in such harsh conditions.
