False staghorn fern (Dicranopteris linearis)

Resam or false staghorn fern (Dicranopteris linearis) is a plant species in the Gleicheniaceae, a common fern with stems growing from rhizomes, cylindrical in shape, straight, branching at an angle of 45 degrees, forming fronds that continuously sprout and branch.

D. linearis has white sorus and appears on the underside of the leaf, lining up along the left and right of the veins. Rhizomes spread by cloning, spreading along the ground and climbing other vegetation, often forming thickets 3 meters or more deep.

Colonies of this species form mats that are layered. The branches can reach over 6 meters in length and can climb up to 10 meters high if supported by the tree. The last leaf segment is linear, up to 7 cm long and a few millimeters wide. The underside is hairy and sometimes waxy.

This fern grows easily in infertile, nutrient-poor soils, disturbed habitats and steep slopes. This species dominates many areas of the rainforest as a pioneer species in ecological succession and colonizes empty sites such as lava flows, talus and abandoned roads.

When it grows in a new place it will produce layers of stems and leaves repeatedly until there is a network of vegetation. Dead leaves and stems decompose very slowly, so the tissue remains. The network is then filled with organic forest detritus, forming a layer of litter up to 1 meter thick.

The tissue is penetrated by rhizomes and roots, thereby serving as a substrate in itself. These ferns may have allelopathic effects and prevent the growth of other plants. This plant is used to treat worms, boils, skin wounds, fever and kill bacteria.

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 ...

Perikapur (Microchirita caerulea)

Perikapur ( Microchirita caerulea ) is plant species in Gesneriaceae, herbaceous, non-woody, upright, growing up to 65 cm tall. Its stems are straight, cylindrical, and bright green. Its roots are fibrous and white, clinging to limestone surfaces and cliffs in karst landscapes. M. caerulea grows in sparse or distant colonies. The stems are erect, straight, cylindrical, bright green, reddish, or brownish, and have white hairs. The leaves are opposite, with petioles up to 5 cm long. The leaf blades are oval, up to 14 cm long, up to 8 cm wide, and have pointed tips. The upper side is green, with white, and rough hairs. The underside is bright green. A main vein runs through the center and minor veins run laterally. The inflorescences grow above the leaf blades. The flowers are fan-shaped or trumpet-shaped and hairy, 2 cm long and 1 cm wide, with violet stripes on the upper side. The leaf blades are green, butterfly-shaped, and have white, and rough hairs. The leaves grow from the leaf ...
