Monkey pod tree (Samanea saman)

Trembesi or rain tree or monkey pod tree (Samanea saman) is a species of plant in the Fabaceae, a large tree, 30-40 meters high, 4.5 meters in diameter, tree crown 40-60 meters, irregularly shaped trunk, sometimes bent and swollen big.

S. saman has compound leaves with stalks about 7-15 cm long, 4-5 cm wide, dark green in color, the lower surface is velvety and soft. The leaves will fold when it rains and at night.

Flowers are white and bright red spots on the top, 10 cm long from base to tip. The crown tube is 3.7 cm long and has 20-30 stamens 3-5 cm long. Nectar for insects are very fond of.

The pods are straight, slightly curved, 10-20 cm long, 1.5-2 cm wide and 0.6 cm thick. The fruit is dark brown when ripe. Seeds embedded in reddish-brown flesh, very sticky, sweet containing 5-25 seeds with a length of 1.3 cm.

Trembesi absorbs 28.5 tons of carbon dioxide every year which an ordinary tree absorbs only 1 ton in a 20 year lifetime. This tree is also able to reduce gas concentrations effectively, without reforestation and has a strong ability to absorb groundwater.

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 ...

Broad sword fern (Nephrolepis biserrata)

Broad sword fern ( Nephrolepis biserrata ) is a species of fern in the Nephrolepidaceae, epiphytic and terrestrial, with grayish-brown stems, brown hairs, and 10–130 cm long. The leaf blades are green, 7 cm long, 1.5 cm wide, and hairy brown on the underside. The sori are attached to the underside of the leaf blade, with about 60 sori along the edge and are brown in color.

Rubber tree (Hevea brasiliensis)

Rubber tree ( Hevea brasiliensis ) is a plant species in Euphorbiaceae, a tree height of 15-25 m, but in the wild up to 43 m, a large trunk, grows straight and has a high branching above. The stem of this plant contains milk sap which is extracted as the main source of natural rubber. H. brasiliensis has a cylindrical rod, brown and the inner skin secretes latex if injured. The leaves have three leaflets, arranged in a spiral, elliptical, elongated with a tapered tip, flat edge and bare. The main leaf stalk has a length of 3-20 cm and a minor leaf stalk for 3-10 cm. Male and female flowers are separate, yellowish and have no petals. The fruit is a capsule that contains three and six seeds according to the amount of space, blackish brown with typical patterned spots and explosively open when ripe. Rubber trees need a tropical or subtropical climate with a minimum rainfall of 1,200 mm per year and no frost. Tapping is one of the main activities of exploitation of this plant by op...
