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 ...

Jomblang Cave

Jomblang Cave or Luweng Jomblang is a 50-meter vertical collapse doline type cave in Gunung Kidul Regency, Yogyakarta Province, Indonesia. This cave was formed due to geological processes in which soil and vegetation on the surface collapsed to the bottom of the earth into a sinkhole thousands of years ago into ancient forests in the cave. Inside the cave grows endemic vegetation and a place for conservation of ancient plants. Sunlight bursts into 90 meters of Luweng Grubug to form a light pole, illuminating the beautiful flowstone and water dripping from a height in a dark room. Characteristics Jomblang Cave is one of the caves of hundreds of caves in the Gunung Sewu Geopark . This doline collapse cave is formed due to the surface process collapsing and forming a sinkhole. Ancient plants that lived on the surface also fell to the bottom of the earth, adapted and continued to grow until now as a very rare endemic plant. This cave has a mouth hole 50 meters wide and 60 meters ...

Artocarpus altilis var. altilis and Artocarpus altilis var. camansi, the differences

SPECIES HEAD TO HEAD - Genus Artocarpus J.R.Forst. & G.Forst. has more than 70 recorded species of which breadfruit ( Artocarpus altilis (Parkinson) Fosberg) and breadnut ( Artocarpus camansi Blanco) grow in tropical areas, both species are medium to large trees and have many similarities. Some researchers doubt both nomenclatures. I agree that both species should be one species. A. altilis is the domesticated version and widely cultivated in its history, while A. camansi is the original or wild version and has never undergone domestication in history. Both species have overall similarities including the shape and size of habitus, stem, leaves, flowers and fruit. The only differences are in the skin of the fruit and the size of the seeds as an impact of human cultural selection. A. altilis has fruit with a pericarp in the form of small and short thorns, while the number of seeds is small and small in size. A. camansi has fruit with a pericarp in the form of larger and long...
