Red cotton tree (Bombax ceiba)

Randu alas or kapok alas or red silk-cotton or red cotton tree (Bombax ceiba) is a species in Malvaceae like other trees commonly known as cotton trees. This tropical tree has perpendicular stems and deciduous leaves in winter. Red flowers with 5 petals appear in the spring before the leaves grow new.

B. ceiba produces capsules containing white fibers such as cotton. Old trees up to 60 meters in the wet tropics, but wood is too soft to use. Young stems and branches are equipped with cone spines, but eroded with age.

The palate leaves have 6 leaflets radiating from the center point or the tip of the petiole, 7-10 cm wide, 13-15 cm long. Flexible leaf stalks up to 20 cm long. Solitary or clustered cup-shaped flowers, axilla or sub-terminal, follicular near the tip of the branch, on average 7-11 cm wide, 14 cm long, petel up to 12 cm long.

Short staminal tube, more than 60 in 5 bundles. The stigma is bright red, 9 cm long, the ovary is pink to 1.5-2 cm long with skin covered in white silk hair for 1 mm in length. Many seeds, long, ovoid, black or gray and packed in white cotton.

The fruit has a length of up to 13 cm, is green when young but becomes brown when ripe. Flowers are very attractive to wildlife where many birds make holes in unopened flower buds. Honey bees collect pollen and many insects gather.

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

Ngamugawi wirnagarri reveals evolution of coelacanth fish and history of life on earth

NEWS - An ancient Devonian coelacanth has been remarkably well preserved in a remote location in Western Australia linked to increased tectonic activity. An international team of researchers analysed fossils of the primitive fish from the Gogo Formation of Ngamugawi wirngarri , which straddles a key transition period in the history of coelacanths, between the most primitive and more modern forms. The new fish species adds to the evidence for Earth’s evolutionary journey. Climate change, asteroid strikes and plate tectonics are all key subjects in the origins and extinctions of animals that played a major role in evolution. Is the world’s oldest ‘living fossil’ the coelacanth still evolving? “We found that plate tectonic activity had a major influence on the rate of coelacanth evolution. New species are more likely to have evolved during periods of increased tectonic activity when new habitats were divided and created,” says Alice Clement of Flinders University in Adelaide. The Late Dev

Species going extinct every day and without warning

NEWS - The current rate of human-caused extinction is up to 700 times higher than it was in the past. Extinctions are no different for plants, animals and fungi, although the extinctions of botanicals and invertebrates have been far worse than those of vertebrates. The mass extinctions increased from 1890 to 1940, but a decline in extinctions was only recorded after the 1980s, likely due to taxonomic bottlenecks and the pre-1800 extinction rates being affected by a lack of data. The number of species varies from 2-8 million to 1 trillion, and estimates suggest that most species, especially microbes and fungi that may be key to healthy ecosystems, are still undiscovered. The biodiversity crisis is therefore extremely difficult to measure. “If we don’t know what we have, it’s impossible to measure how much we’re losing. This taxonomic gap urgently needs to be addressed,” say Maarten Christenhusz and Rafaël Govaerts of the Royal Botanic Gardens, Kew. Yet taxonomy is in decline. Misunderst
