Teak (Tectona grandis)

Jati or teak (Tectona grandis) is a plant species in the Lamiaceae, a large tree producing high-quality and luxurious wood, straight trunk, up to 40 m high, large leaves, slow growth with low germination making natural propagation difficult and insufficient to meet demand market.

T. grandis grows in deciduous forests that lose their leaves in the dry season, stems are cylindrical, straight, up to 40 m high, 2.4 m in diameter, 18-20 m clear bole and the bark is yellowish brown.

The leaves are ovate, opposite, very short stalks, fine hairs and glandular hairs on the underside. The leaves on the tree shoots are 60-70 cm wide, 80-100 cm long and reddish green in color. The leaves on an old tree are 15 cm wide and 20 cm long.

Compound inflorescences in large panicles, 40x40 cm, containing hundreds of flowers arranged like umbrellas, located at the tip of the twig at the top of the tree. Flowers have 6-7 corolla, whitish in color and 8 mm wide.

The fruit is round, slightly flattened, 2.5 cm, coarse hair with a thick core, 2-4 seeds but generally only one grows. The fruit is covered by enlarged flower petals that inflate like small balloons.

Teak can grow in areas with rainfall 1500-2000 mm / year, temperature 27-36C, pH 6-8, contains lots of calcium and phosphorus, is not stagnant water and lots of sunshine throughout the year, the ideal elevation is 0-700 meters.

Teak is a pioneer species that is fire-resistant and damage to the teak seed shell makes it easier for shoots to come out when the rainy season arrives. Wood has strength class II, durability class I-II and is resistant to termite attacks. The wood of the patio has a light brown to reddish brown color. The sapwood is white and yellowish gray.

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 ...

Petai (Parkia speciosa)

Stink bean or bitter bean or pete or petai ( Parkia speciosa ) is a tropical tree species in Fabaceae, 5-25 m high and branched, reddish brown bark, always green, compound and pinnate leaves, young seeds are harvested as fresh or boiled food . P. speciosa has a hump-shaped flower that hangs with a long stalk, usually appearing near the tips of the branches. Flowers that are young and not yet blooming are green, mature flowers have stamens and pistils, old flowers turn yellow and are large in size. Dozens of long, flat pod-shaped fruits emerge from a flower hump hanging from a tree. Each pod has up to 10-20 seeds that are neatly arranged, green when young and wrapped in a rather thick membrane of light brown. The fruit dries and becomes harder as it ripens and releases the seeds. Petai grows well in wet and slightly wet climates, low land to mountains with an altitude of 1,500 m, open spaces and lots of sun throughout the day with fine-tinted soil and Ph 5.5-6.5. Trees start bea...
