A new study that analysed natural oak-dominated forests and modified forests of western Himalayas has noted that there was a drastic loss of bird species in all modified landscapes.
The researchers studied six major land-use types which included natural oak forest, degraded oak forest (lightly used), lopped oak forest (intensively used), pine forest, agricultural cultivation area.
The results showed that there was a low diversity of species in monoculture areas and urban sites. They also noted a drastic loss of pollinator birds and insectivores in the degraded forests, monocultures and urbanised sites.
The researchers noticed that many of the species that dropped out of the modified land areas were recognised oak forest specialists such as rufous-bellied woodpecker, greater yellow nape, rufous sibia, white-throated laughing thrush and black-faced warbler.
Researchers at IIT Mandi in Himachal Pradesh have revealed the part of structure of a key protein in COVID-19 virus, which helps in understanding its mode of action, its role in the spread and severity of the disease and development of antiviral therapeutics.
The current COVID-19 treatments simply manage symptoms while the body fights off the infection with its immune defence system.
This virus has 16 non-structural proteins (NSP1–NSP16), of which the NSP1 plays a vital role in the pathogenicity (ability to cause disease) of the virus.
The NSP1 disrupts the proteins of the host cell and suppresses its immune functions. Its importance can be understood by the fact that it is also called the ‘host shutoff factor’.
