The correct answer is Option 1.

In News

• A new species of beetle, Spathaspina noohi, was recently discovered from the forests of Meghalaya, adding to India’s entomological diversity.

Key Points

• The beetle was discovered in the Umran area of Ri Bhoi district, Meghalaya, and it belongs to the Curculionidae (weevil) family, known for its ecological and agricultural roles. Hence, Statement I is correct.
• Due to its prominent sword-like spine, researchers assigned it to a new genus within the subfamily Ceutorhynchinae, combining Latin terms spatha (sword) and spina (spine). Hence, Statement II is correct.
• Beetles in the subfamily Ceutorhynchinae are found globally, but not in Antarctica, Oceania, New Zealand, and southern South America. Hence, Statement III is incorrect.

Additional Information

• Weevils are a type of beetle under the family Curculionidae, which includes over 60,000 species worldwide.
• While many are agricultural pests, some species like Spathaspina noohi help regulate invasive plant species and support ecological balance.
• Ceutorhynchinae beetles can often be identified by their stout bodies, a snout (rostrum) they tuck between their legs when resting, and their visible mesanepimera (except in a few genera).
• The discovery highlights the rich biodiversity of Northeast India, particularly in regions like Meghalaya.

The correct answer is Japan.

Key Points

• In 2016, researchers from Japan discovered a strain of bacteria capable of breaking down and consuming polyethylene terephthalate (PET) plastic.
• The bacteria, named Ideonella sakaiensis, was found at a waste recycling center outside of Osaka.
• Ideonella sakaiensis uses two enzymes to hydrolyze PET into its monomers, which are then assimilated by the bacteria.
• This discovery offers potential solutions for addressing plastic pollution, a significant environmental concern globally.

Additional Information

• Polyethylene Terephthalate (PET)
  • PET is a type of plastic commonly used in packaging, including bottles and containers.
  • It is known for its strength, thermal stability, and transparency, making it widely used in the food and beverage industry.
  • PET is non-biodegradable and poses significant environmental challenges due to its persistence in the environment.
• Plastic Pollution
  • Plastic pollution refers to the accumulation of plastic objects and particles in the Earth's environment adversely affecting wildlife, wildlife habitat, and humans.
  • It is a major environmental issue, with millions of tons of plastic waste entering the oceans each year.
  • Efforts to mitigate plastic pollution include recycling, bioplastics, and reducing plastic use through policy measures.
• Biodegradation
  • Biodegradation is the process by which organic substances are broken down by the actions of living organisms, typically microorganisms.
  • This process is essential for the natural breakdown of waste products and is crucial in waste management and environmental cleanup.
• Enzymatic Hydrolysis
  • Enzymatic hydrolysis is a process where enzymes break down complex molecules into simpler ones, often used in the degradation of plastics.
  • In the context of PET degradation, specific enzymes break the ester bonds in the polymer to produce monomers that can be further metabolized by microorganisms.

Important Points

• Named after Sri Lankan taxonomist Rohan Pethiyagoda, the frogs of the new genus Rohanixalus are characterised by a rather small and slender body (size about 2 to 3 cm long). Hence Option 1 is Correct.
• Based on DNA studies, the new genus is also revealed to be a distinct evolutionary lineage from all previously known tree frog genera.
• There are eight frog species in this genus Rohanixalus. They are known to inhabit forested as well as human-dominated landscapes right from the northeast to Myanmar, Thailand, Malaysia, Indonesia, Vietnam, Laos, and Cambodia, up to southern China.
• The genus has several unique behavioural traits including maternal egg attendance where the female (mother) attends the egg clutches until hatching and assists in the release of the tadpoles into the water. During the first three days after egg-laying, the female sits over the eggs and produces a gelatinous secretion with which she glazes the egg mass through the clock-wise movement of her legs.
  This behaviour provides necessary moisture to the eggs laid on exposed leaf surfaces and protects them from insect predation.
