Dry Valleys on Antarctic continent is the driest place in the world

The Sahara Desert is the largest desert in the world, rainfall is very low, only stretches of sand and rocks without rivers and plants further strengthen the view of drought. However, it turns out that the place is not the driest place in the world. Dry Valleys in Antarctica, although the continent is covered in ice, but has one part that is completely dry.

Although the average rainfall in most of the Sahara Desert is less than 20 millimeters per year, there are still drier places. Dry Valleys in Antarctica is much drier where the average rainfall is 0 millimeters per year and gets the title of the driest place in the world.

The valleys have so low humidity that there is almost no ice. This is the largest ice free place on the Antarctic continent. The area is surrounded by mountains that block ice from flowing into the valley.

Drought is also caused by strong katabalic gusts from mountain peaks where cold air blows down the hill due to gravity. The wind has speeds of up to 322 kilometers per hour and causes the layers of water, ice, and snow to evaporate, making it even more dry.

The uniqueness of Dry Valleys is considered to be very similar to the landscape on the surface of Planet Mars. The scientists continued to research the Dry Valleys ecosystem to better understand the condition of the Red Planet.

Broad-leaved dock (Rumex obtusifolius)

Broad-leaved dock ( Rumex obtusifolius ) is a species of plant in the Polygonaceae, herbaceous perennial, growing broadly, up to 150 cm tall, large, oval-shaped leaves with a heart-shaped base and rounded tip, large taproot with many branches extending to a depth of 150 cm. R. obtusifolius has leaves up to 30 cm long, 15 cm wide and green. Stems are long, hard, alternate, green or reddish in color and unbranched until just below the inflorescence. A main vein in the middle and green or reddish in color. Flat or wavy surface. The inflorescences consist of large clusters of racemes that contain small, greenish flowers that turn red as they mature. Seeds are reddish brown and dry. Broad-leaved dock grows in fertile soils, grasslands, waste lands, roadsides, ditches, coastlines and riverbanks, forest margins, forest clearing and agricultural land. The leaves are used as a salad to make vegetable broth or cooked like spinach. Dried seeds are used as a spice. Kingdom: Plantae Phylum: Tr...

Khorat butterfly lizard (Leiolepis glaurung) adapts to rocky habitats for the first time in the genus

NEWS - A new species of rock-dwelling butterfly lizard (Leiolepis Cuvier, 1829) has been described from the Khorat Plateau in northeastern Thailand. This new report of Leiolepis glaurung brings the number of Leiolepis species in Thailand to six and worldwide to 11, and is the first case of an ecological adaptation to survive in a rocky habitat. L. glaurung can be distinguished from all other sexual species of Leiolepis by its combination of a black gular region with a broad yellow medial stripe, a yellow ventrum with black spots, bright red to orange subcaudal coloration, sides that can expand and retract to none, and only a single black transverse stripe on its sides. The researchers hypothesize that this morphology is an adaptation to reduce the diameter of its body to better fit into smaller rocky burrows, unlike the larger and deeper burrows built in looser soil by other species. The new specimen lives on the Khorat Plateau and is phylogenetically, ecologically, and morphologic...

Twoleaf nightshade (Solanum diphyllum)

Twoleaf nightshade ( Solanum diphyllum ) is a species of plants in Solanaceae, upright shrubs grow in shade, 1-2 m tall, rounded stems, dense, green-purple brown, short hairy, stopping cells, cornered young twigs and widely cultivated as plants decorate with bright yellow ripe fruit. S. diphyllum has leaves that are alternating, solitary or paired in twigs with generative organs. Some are stemmed for 1-1.5 cm. The leaves are oval to oblique round eggs, dynamic base, flat or wavy edges, tapered or rounded edges, 1-14.5 cm long, 0.5-4 cm wide and have short hair. Flowers facing leaves 5-25 mm long. Has a 2 mm handle, brownish purple, straight and unbranched. Hook 5-10 mm, greenish to brown and curved. The petals have five ears, resembling kupula, pale green, 1-5 mm long and short haired. Flowers have five crowns, coincide, star-shaped, yellowish white, 2-5 mm long. Has five stamens, free and facing the crown. Short and yellowish green pistil. The stigma is yellow, attached to the...
