Mangrove palm (Nypa fruticans)

Nipah or mangrove palm (Nypa fruticans) is a species of plant in the Arecaceae, the stems spread along the ground, forming rhizomes that are submerged in mud and only the rosette of leaves appears above the ground, the fibrous roots grow up to 13 meters and the clumps can be washed away by water until to the sea.

N. fruticans has rhizomes that produce compound and pinnate leaves, upright up to 9 meters above the ground. The stalk is 1-1.5 meters long with a hard and shiny surface, green when young and brown to black as it ages. The inside is soft like cork.

The minor leaves are elongated ribbon-shaped and have a pointed tip and have veins. Up to 100 cm long and leaves 4-7 cm wide. Young leaves are yellow and old leaves are green. Each enthal has 25-100 strands.

Compound flower bouquets appear in the leaf axils. Each strand has 4-5 male flowers with a length of 5 cm. The male flower is protected by a sheath, but the part filled with pollen remains visible.



The female flowers are collected at the tip to form a ball and the male flowers are arranged in panicles, red or orange or yellow on the branches below. The female flowers are bullet-shaped and bent towards the side. Flower stalk length 100-170 cm. The flower bunches can be tapped for sap.

Stone fruit with fibrous mesocarp, inverted oval and flattened, 2-3 ribs, reddish brown, 16 cm long and 13 cm wide, collected in tight clusters resembling a ball with a diameter of 121 cm. The exocarp is smooth, the mesocarp is fibrous and the endocarp is hard like a shell.

The seeds are protected by a shell with a length of between 8-13 cm and are conical in shape. Each bunch has 30-50 grains, packed together to form a round fruit cluster. Ripe fruit falls into the water and floats with the tidal currents until it is caught in a place to grow.

This species grows at temperatures of 20-35C in swamp areas, rainfall of more than 1500 mm/year, coastal climate and elevation of 0-10 meters in fine, watery mud, pH 6-6.5, salinity 50-100 mmosh/ cm3 and optimum salt concentration 1-9/mil. Usually grows in pure stands, but in some areas it grows mixed with other mangrove trees.

Each tree produces 0.4-1.2 liters of sap every day. Nira contains 13-17% sucrose to be processed into bioethanol and sugar. This tree is also used for house roofs and craft materials. Young leaves for cigarette paper. Palm leaf stalks and midribs for firewood. Leaf midribs also contain cellulose for pulp. Sticks are used for brooms, woven materials and ropes. The young fruit and seeds are eaten, the old fruit is ground to make flour.

Plants contain essential amino acids (histidine, arginine, theronine, valine, methionine, isoleucine, leucine, phenyl alanine and lysine), alkaloids, steroids, triterpenoids, flavonoids, tannins, polyphenols, chlorogenic acid and kaempferol. This tree is used to treat toothache and headaches, improve the digestive tract, reduce fever, antidote, sedative, cough, sore throat and anticancer.

Elephant bell gourd (Trichosanthes tricuspidata)

Elephant bell gourd ( Trichosanthes tricuspidata ) is a plant species in the Cucurbitaceae, stems grow elongated to propagate or climb, many branches, cylindrical in shape and green in color. T. cochinchinensis has stem tips or branches that twist to attach themselves to a support or other plant. It grows to climb to cover a support, usually on another plant, up to several meters and creeps along the ground to reach another support. Arrow-shaped leaves, split base, sharp apex and two wings at an acute angle, have many veins ending at a sharp edge, green and have a long petiole. Single flower is white. The fruit is round to oval, ends with a tail, young green and turns red with maturity, thin skin, thick flesh and reddish yellow, has a short stalk and hangs. The seeds are in the middle of the fruit. Seeds are white, oval and flat. Black coated seeds. Elephant bell gourd grows wild in primary and secondary forests, agricultural land, roadsides, watersheds, especially on slopes, damp a

Yellow fever mosquito (Aedes aegypti) use thermal infrared to navigate hosts

NEWS - Aedes aegypti transmits the viruses that cause dengue, yellow fever, Zika and other diseases every year, while Anopheles gambiae transmits the parasite that causes malaria. Their capacity to transmit disease has made mosquitoes the deadliest animals. Moreover, climate change and global travel have expanded the range of A. aegypti beyond tropical geography. The mosquitoes are now present in subtropical climates that were previously unheard of just a few years ago. Male mosquitoes are harmless, but females need blood for egg development. There is no single cue that these insects rely on to feed; they integrate information from many different senses across a wide range of distances. " A. aegypti very adept at finding human hosts. This work provides a new insight into how they achieve this. Once we got all the right parameters, the results were clear and undeniable," says Nicolas DeBeaubien of the University of California at Santa Barbara UCSB. The researchers added

Banded dragonfish (Akarotaxis gouldae) diverged from Akarotaxis nudiceps 780,000 years ago

NEWS - A new species of dragonfish, Akarotaxis gouldae or banded dragonfish, off the western Antarctic Peninsula by researchers at the Virginia Institute of Marine Science at Gloucester Point, the University of Oregon at Eugene, and the University of Illinois at Urbana-Champaign, highlights the unknown biodiversity and fragile ecosystems of the Antarctic. A. gouldae was named in honor of the Antarctic Research and Supply Vessel (ARSV) Laurence M. Gould and crew. The larval specimen was collected while trawling for zooplankton and was initially thought to be the closely related Akarotaxis nudiceps hundreds of thousands of years ago. DNA comparisons with A. nudiceps specimens held in collections at the Virginia Institute of Marine Science, Yale University, and the Muséum national d’Histoire naturelle in Paris showed significant variation in mitochondrial genes that suggested the larval sample was a distinct species. Andrew Corso of the Virginia Institute of Marine Science and colle

A deep-sea isopod Bathyopsurus nybelini adapted to feed submerged Sargassum algae

NEWS - Incredible footage shows a marine species, Bathyopsurus nybelini , feeding on something that sinks from the ocean’s surface. Researchers using the submersible Alvin found the isopod swimming 3.7 miles down using its paddle-like legs to catch an unexpected food source: Sargassum. Researchers from Woods Hole Oceanographic Institution (WHOI), the University of Montana, SUNY Geneseo, Willamette University and the University of Rhode Island found the algae sinking, while the isopod waited and adapted specifically to find and feed on the sinking nutrient source. The Sargassum lives on the surface for photosynthesis. The discovery of a deep-sea animal that relies on food that sinks from the waters miles above underscores the close relationship between the surface and the deep. “It’s fascinating to see this beautiful animal actively interacting with sargassum, so deep in the ocean. This isopod is extremely rare; only a handful of specimens were collected during the groundbreaking Swedis
