Desert is a barren area of landscape where little precipitation occurs and consequently living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation. About one third of the land surface of the world is arid or semi-arid. This includes much of the polar regions where little precipitation occurs and which are sometimes called polar deserts or “cold deserts”. Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. — Wikipedia

Science

Desert climate, also known as an arid climate, is a climate in which precipitation is too low to sustain any vegetation at all, or at most a very scanty shrub, and does not meet the criteria to be classified as a polar climate.

An area that features this climate usually experiences from 25 to 200 mm (7.87 inches) per year of precipitation and in some years may experience no precipitation at all. Averages may be even less such as in Arica, Chile, where precipitation normals annually stand at around 1 mm per year. In some instances, an area may experience more than 200 mm of precipitation annually, but is considered a desert climate because the region loses more water via evapotranspiration than falls as precipitation (Tucson, Arizona, and Alice Springs, Northern Territory, are examples of this). — Wikipedia

  • Tree species diversity under pressure
    on June 22, 2022 at 3:35 pm

    In a new global study of more than 46,000 species of trees, an international team of researchers has shown that many tree species are under substantial pressure and poorly protected. The research team, headed by Aarhus University, has also studied how this situation can be improved by means of ambitious and smart designation of new protected natural areas.

    on June 20, 2022 at 1:39 pm

    As greenhouse effects become increasingly prominent, soil carbon has been a major focus of research on climate change. Soil microorganisms are the key groups that drive soil carbon transformation. Due to the complexity of factors such as microbial physiology, the composition of organic compounds in soils, and variation among redox forms, the pattern and process of the soil carbon cycle at the microbial community level can be difficult to study using metagenomics.

    Drought and desertification threatens to degrade land in Europe and around the world.

    Leaf calorific value is an important trait that indicates how efficiently a plant utilizes natural resources to capture energy. However, prior research on leaf calorific values mainly focused on forest plants. The characteristics of the leaf calorific values of desert plants are not well understood.

    on June 9, 2022 at 11:20 am

    An Egyptian-American team of researchers has announced the discovery of a new kind of large-bodied meat-eating dinosaur, or theropod, from a celebrated fossil site in Egypt's Sahara Desert. The fossil of a still-unnamed species provides the first known record of the abelisaurid group of theropods from a middle Cretaceous-aged (approximately 98 million years old) rock unit known as the Bahariya Formation, which is exposed in the Bahariya Oasis of the Western Desert of Egypt.
