Thatch screwpine (Pandanus tectorius)

Pandan duri or pandan tikar or thatch screwpine (Pandanus tectorius) are species of tree-like plants in Pandanaceae, dioesis, are highly variable in shape and character, have many varieties and some are cultivated for different purposes.

P. tectorius is a wide-branched shrub, 3-7 m high and sometimes has many trunks. Roots and hanging roots have a large size and striking. Ribbon-shaped leaves, 70-250x3-9 cm, stiff, bluish green and waxy, parallel with bones, spines on the edges and underside of the leaf bone.

The leaves gather tightly at the end of a branch in 3 rows arranged in a spiral with the base hugging the stem to leave a ring-shaped mark. Hanging male flowers, 25-60 cm long, 10-20 side branches, veiled in a white-yellow sheath that smells good. The female flowers are aloof, rounded hump shaped and 5 cm in diameter.

Compound fruit has many variations for shape, size and color. Shapes ranging from ovoid, ellipsoid, almost round and full ball. Length 8-30x4-20 cm on the center line. Phalanges are ovoid inverted to oblong, 2.5-11x1.5-6.7 cm and the skin is green, yellow, orange and red when ripe.

Mesocarp is white, fiber and filled with air at the tip, yellow to orange or red-orange at the base. Ovoid seeds, pushing or oval and 6-20 millimeters long. Often grow in sandy and rocky areas at an altitude of 0-610 m, rainfall 1500-4000 mm/year, adapt in various of soil including quartz sand, coral sand, peat, limestone and basalt.

Pandan duri is tolerant of high salt content and continuous gusts of wind, like the soil with a pH of 6-10. It grows very well in full sun, but can also grow well with a shade of 30-50%.







Different varieties produce different benefits. Generally P. tectorius is cultivated for soft and strong leaves to be woven, others for male flowers that smell nice to scent the room, clothes or perfume. Another variety for delicious fruit.

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 k...

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

Tripa tiger moth (Nannoarctia tripartita)
