Sumatran Rhino

  • The Sumatran rhino has become extinct in Malaysia after the last remaining individual died on November 23, 2019, due to natural causes.
  • It is the smallest of all rhino species and one of the most endangered land mammals on the planet.
  • It is the only Asian Rhino with two horns.
  • Its IUCN status is Critically Endangered.
  • Earlier, it has occurred in the parts of Bangladesh, Bhutan, Brunei Darussalam, Cambodia, India, Lao PDR, Myanmar, Thailand and Viet Nam.
  • Now, it exists only in four isolated regions of rainforests on the Indonesian islands of Sumatra and Borneo.

Malabar Tree Toad

  • It is a very rare species of amphibian endemic to the Western Ghats.
  • It is an endangered species that spends most of its life on trees, coming to the ground only during the first monsoon showers to mate.
  • Its population is shrinking mainly due to habitat loss, climate change and Batrachochytrium dendrobatidis, a deadly fungus that has been decimating entire amphibian populations worldwide.
  • The Metastring Foundation, a citizen-based conservation non-profit based in Bengaluru, was awarded a grant of Rs 15 lakh for one year for its project on the Malabar Tree Toad.
  • It is working to train and equip citizens for mapping the range of an extremely rare species of toad as only sporadic records are available.

Wooden Breast Syndrome

  • Researchers have recently found that the Wooden Breast Syndrome affects broiler chickens by making the meat hard and chewy.
  • It is a metabolic disorder characterised by abnormal fat accumulation in the breast muscle tissue.
  • It involves inflammation of the veins in the breast tissue and accumulation of lipid around the affected veins.
  • It is followed by muscle cell death and replacement by fibrous and fatty tissue.
  • An enzyme called lipoprotein lipase is behind the syndrome and it is crucial for fat metabolism.
  • At the onset of wooden breast syndrome, lipoprotein lipase was higher in affected chickens, leading to more fat accumulating in the breast muscles.
  • This is an irregularity because breast muscle fibres in chicken typically rely on sugar molecules for fuel, not fat molecules.
  • It can render the birds unmarketable and cause losses for growers.
