Lipas (Panesthia angustipennis)

Lipas (Panesthia angustipennis) is a species of animal in Blaberidae, a black, winged cockroach, nymphs having brown features on the upper back near the head, decomposer macrofauna which inhabit many wood residues in the forest ecosystem by eating wood that creates cavities producing wood shreds and fecal pellets.

P. angustipennis has a black or dark brown base color. Males have black heads with brown eyes, ocelli and yellowish brown upper lip. Black antenna with pale yellow apical segment. Sternite and reddish brown or black legs.

Females are similar to males, but rounded back margins, anterior pronotum margins with excision. The nymph is black, has four layers of upper back with four yellowish brown marks on the third and fourth layers, the stomach has six or seven layers.

Lipas live in the tropics with many woody trees for altitudes up to 1500 m. Noted four subspecies is Panesthia angustipennis ssp. angustipennis, Panesthia angustipennis ssp. cognata, Panesthia angustipennis ssp. spadica and Panesthia angustipennis ssp. yayeyamensis.

P. angustipennis has a very important meaning in the wood decomposition process including acacia. Wood cavity by macrofauna will expand the surface of the wood to be attacked by decomposer microorganisms. Wood residue is a source of food and a place to live.

Thomas Sutikna lives with Homo floresiensis

BLOG - On October 28, 2004, a paper was published in Nature describing the dwarf hominin we know today as Homo floresiensis that has shocked the world. The report changed the geographical landscape of early humans that previously stated that the Pleistocene Asia was only represented by two species, Homo erectus and Homo sapiens . The report titled "A new small-bodied hominin from the Late Pleistocene of Flores, Indonesia" written by Peter Brown and Mike J. Morwood from the University of New England with Thomas Sutikna, Raden Pandji Soejono, Jatmiko, E. Wahyu Saptomo and Rokus Awe Due from the National Archaeology Research Institute (ARKENAS), Indonesia, presents more diversity in the genus Homo. “Immediately, my fever vanished. I couldn’t sleep well that night. I couldn’t wait for sunrise. In the early morning we went to the site, and when we arrived in the cave, I didn’t say a thing because both my mind and heart couldn’t handle this incredible moment. I just went down...

Bitter vine (Mikania micrantha)

Sembung rambat or bitter vine ( Mikania micrantha ) is a plant species in Asteraceae, crawling or wrapped around trees, perennial that grows up to 27 mm per day in tropical climates, branched stems where heart-shaped or triangular leaves are arranged in pairs and a plant can cover more than 25 square meters in a few months. M. micrantha has square-shaped stems or longitudinal bones, light green, many branches and has fine hairs. The stems have segments for lengths of 75-215 mm, each segment has a pair of leaves, new shoots and flowers. New roots grow when the segments come in contact with the soil. The leaves are in pairs and facing each other. Strands do not have hair, heart-shaped or triangular with jagged edges, length 30-125 mm, width 15-60 mm. Petiole is 1-6 cm long and has fine hairs. The flower panicle grows from the armpit of the leaf and the tip of the stem, having 3-15 mm long stems. Each flower head has 4 minor flowers. The crown is greenish-white, tubular and measures ...

Cogon grass (Imperata cylindrica)

Alang-alang or cogon grass ( Imperata cylindrica ) is a plant species in Poaceae, annual grass, sharp leaf, long buds and scaly, creeping under the ground, very adaptive and grows in all climates which often become weeds on agricultural land. I. cylindrica has a sharp pointed tip of the bud and emerges from the ground, height of 0.2-1.5 m but in other places it may be more, short stems, rising up to the ground and flowering white or purplish, often with wreath of hair under the segment. Leaf strands in the form of long ribbons, lancet-tipped with a narrow base and gutter-shaped, 12-80 cm long, very coarse edge and jagged sharply, long hair at the base with broad, pale leaf bones in the middle. The flowers are panicles, 6-28 cm long with long-haired and white-colored ears for 1 cm which are used as a tool to blow off the fruit when ripe. Cogon grass breeds quickly with seeds that spread quickly with the wind or through rhizomes that quickly penetrate the soil. Alang-alang does...
