Beach morning glory (Ipomoea pes-caprae)

Katang-katang or tapak kuda or beach morning glory (Ipomoea pes-caprae) is a plant species in the Convolvulaceae, growing up to 30 meters long on sandy beaches and rock cliffs, green-brown stems, roots on each segment and secretes white latex.

I. pes-caprae has leaves that sit spread out, stalks 2-3 cm long, sap is white and oozes when broken. Leaf blade in the shape of a butterfly wing, divided at the tip and base, elongated round, thick, smooth and shiny surface, hairless, green in color and flat edge.

Compound inflorescences with one or more flowers. The flowers are funnel-shaped and purple in color. The stalk is 3-16 cm long. Calyx is not the same, somewhat hideous, trumpet-shaped corolla and purple to reddish.

Dehiscent fruit, round to slightly flat capsule, 12–17 mm long and four seeds. Seeds are black and tightly haired, light and brown, 6–10 mm.

Beach morning glories have a pan-tropical distribution along beaches or rocky soil containing sand. It often grows just behind the tidal line on the beach. It also grows on land, along roadsides and ditches, up to an elevation of 800 meters.

Rural communities believe hoof is used to treat constipation, stomach cramps and pain, prevent swelling from jellyfish stings, abscesses and speed up boils, difficulty urinating, preventing edema and kidney problems.

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 ...

Takenoshin Nakai swallow-wort (Vincetoxicum nakaianum) replaces V. magnificum and C. magnificum

NEWS - Researchers reported an erect herbaceous species distributed in the eastern part of Honshu Island, Vincetoxicum magnificum (Nakai) Kitag. based on Cynanchum magnificum Nakai, nomen nudum. Therefore, they named this species Takenoshin Nakai swallow-wort ( Vincetoxicum nakaianum K.Mochizuki & Ohi-Toma). Vincetoxicum Wolf (Asclepiadeae) is the third largest genus in the Asclepiadoideae consisting of about 260 species geographically extending from tropical Africa, Asia and Oceania to temperate regions of Eurasia. A total of 23 species are known from Japan, including 16 endemic species. Molecular phylogeny divides Japanese Vincetoxicum into four groups: the “Far Eastern” clade consisting of 11 endemic species and 4 more widespread species, 1 sister species to the “Far Eastern” clade, the “subtropical” clade consisting of 2 species and the “Vincetoxicum s. str.” clade consisting of 5 species. V. magnificum (Nakai) Kitag. (Japanese: tachi-gashiwa) is closely related to V. macro...

Sweetpotato bug (Physomerus grossipes)

Kutu ketela or sweetpotato bug ( Physomerus grossipes ) is an insect species in Coreidae, brown with black legs, adults growing about 2 cm long, oval shaped, segmented antennas, heavily veined membranes, metathoracic odor glands and enlarged rear tibia. P. grossipes generally live in Leguminosae and Convolvulaceae especially sweet potato ( Physomerus grossipes ), pink morning glory ( Ipomoea carnea ), purple beans ( Vigna unguiculata ), Asian pigeonwings ( Clitoria ternatea ) and common bean ( Phaseolus vulgaris ). Sweetpotato bugs suck liquid from the stem which causes plants to wither and disrupt fruit production. P. grossipes places eggs at the bottom of the leaves or stems or grass around them. Females are very protective of their children, keeping eggs and nymphs from predators as the most famous example of maternal care in Coreidae. Even so, about 20% of eggs are eaten by predators such as ants and 13% are lost by parasitoid predation by chalcid wasps which lay eggs in egg...
