Javan pond heron (Ardeola speciosa)

Blekok sawah or Blekok Jawa or Rice field heron or Javan pond heron (Ardeola speciosa) is a species of bird in the Ardeidae family, about 46 cm long, living around rice fields to eat eels, fish, crabs and insects. This bird has white, brown and black.

A. speciosa has a yellow and black beak on the tip. The head and neck are light brown, the chest is dark brown, the abdomen is white and the back is black. Long yellow legs. Blekok sawah has a small size in the Ardeidae family.

In the non-breeding period, the back color is browned. When flying wings look very contrast with a black back. These birds live alone or in scattered groups to make nests in tree canopies in large colonies with other water birds.

Nests are constructed from stacks of twigs on branches or leafy branches in tall trees around the water environment in urban and rural areas. This bird is accustomed to living side by side with humans. Females breed in December-May and January-August for 2 to 3 pale green blue eggs.

A. speciosa spends days around rice fields, rivers or freshwater swamps. Stand with low body position and head pulled to wait for prey. Every afternoon fly to the resting place with a slow flap, in pairs or three.

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
