Northern wattle (Acacia crassicarpa)

Northern wattle (Acacia crassicarpa) is a species of plant in the Fabaceae, small or medium tree, up to 25 meters tall, upright trunk, up to 50 cm in diameter, bark brown or gray or dark red, hard, linearly fissured fibrous .

A. crassicarpa has crescent-shaped leaves, 8-27 cm long, 1-4.5 cm wide, grayish green or silvery green, pointed at the tip, has three main veins and is yellowish in color.

The inflorescences are grain-shaped, bright yellow and 4-7 cm long. The flower stalks are thick, 5-10 mm long, five-strand corolla 1.3-1.6 mm long and bisexual.

The pods are flat and wide. Seeds are round, flat and black.

Northern wattle easily adapts to the environment, tolerant of pH 3.5-6, grows at elevations of 200-700 meters and rainfall of 1000-2500 mm/year. Salt tolerant in soil, sandy, silt, poorly drained soil and near the sea. It grows in dry areas such as savanna and monsoon forests.

Wood is used as raw material for making pulp and paper, building construction, furniture and raw material for shipbuilding. Trees can be used as cover and shade plants, fix nitrogen free and prevent erosion.

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...
