Awned panick grass (Oplismenus compositus)

Awned panick grass (Oplismenus compositus) is a species of plant in the Poaceae, 15-150 cm long, leaves lanceolate or ovate, 2-16 cm long, 8-35 mm wide, strands veined and have transverse veins, pointed or slightly pointed ends. .

O. compositus has racema composed of inflorescences, grows on the side of the central axis, unilateral and 2.5-11 cm long. The middle inflorescence axis is 5-25 cm long with angular rachis and pilose at the bottom.

The spikelets are arranged in 2 rows, namely fertile, pedicelled and sessile. Stem oblong. The spikelet also has one basal sterile floret and one fertile floret. 2.5-4 mm long and lanceolate.

Glumes are shorter than spikelets and thinner than fertile lemmas. The bottom is ovoid with a tent length of 3-10 mm. The upper glume is ovoid, obtuse and 0-4 mm long.

The flower buds are 2-2.5 mm long, pubescent, emarginate and mucronate. The florets and glumes have a keel. Glume is 5 items and florets are 7-11 items. Fruit linear and 0.5 mm long.

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...
