Sengon gall rust (Uromycladium falcatarium)

Sengon gall rust (Uromycladium falcatarium) is a species of fungi in Raveneliaceae, grows on molucca albizia (Falcataria moluccana) as the host plant, the symptoms vary widely and sometimes are not obvious, the host stem shows brownish lumps to kill slowly.

U. falcatarium infects host shoots at the age of 2-3 weeks which causes the leaves to curl, leg, do not develop normally and fall off easily. At 6 weeks of age, symptoms appear on curved and stiff stems and shoots. At the age of 3 months or more the tumor begins to enlarge.

Symptoms begin with tumefaction on the leaves, branches and stems. Subsequent development creates a lot of brownish green bumps which then become small rashes on part of the stem or the whole.

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 ...

Matchbox bean (Entada phaseoloides)

Matchbox Bean ( Entada phaseoloides ) is a species in the Fabaceae family, a large woody liana with stems up to 18 cm in diameter, dark brown, rough bark, laterally flattened, and spirally twisted. The leaves are bipinnate, up to 25 cm long, with 1-2 pairs of minor leaflets, each divided into 1-2 pairs of pinnules. The pinnules are somewhat leathery, asymmetrical or oblique, up to 10 cm long and 5 cm wide. The inflorescence is a spike-shaped, about 25-30 cm long, bearing numerous sessile flowers. The individual flowers are very small, about 1.2 mm in diameter. The five petals, green with reddish bases, are 3-4 mm long, and the stamens are about 7 mm long. The fruit is a very large, flattened, woody pod or capsule, about 1-1.2 m long and 12 cm wide. It is usually slightly curved and linear, with about 12 segments, each containing a single seed. The seeds are lens-shaped, shiny brown, smooth, 5-6 cm wide and 1-1.5 cm thick. Filipinos used gugo before commercial shampoos were available ...
