Republic of Naoero

World Geography | Pacific island nations

WHY IN NEWS:

The Pacific island nation of Nauru officially changed its name to the Republic of Naoero, restoring its traditional indigenous name to reinforce national identity and cultural heritage.

IN ONE LINE:

Naoero is a tiny raised-coral island republic in southeastern Micronesia, with no official capital and an economy historically shaped by phosphate mining.

Locate it on the map

• Region: Southwestern Pacific Ocean.

• Sub-region: Southeastern Micronesia.

• Position: About 40 km south of the Equator.

• About 1,300 km northeast of the Solomon Islands.

• Nearest neighbour: Banaba Island in Kiribati, about 300 km to the east.

Size and physical geography

• It is the world's smallest independent republic.

• Population: About 12,000.

• Land area: 21 sq. km.

• It is a raised coral island.

• It has no rivers or lakes.

• Its Exclusive Economic Zone extends 200 nautical miles, or about 370 km, from the coast.

Capital, language and currency

• The country has no official capital.

• Yaren District functions as the administrative centre because government offices are located there.

• National language: Nauruan.

• Currency: Australian Dollar (AUD).

Political system

After independence in 1968, its Constitution established a republic based on the Westminster-style parliamentary system.

• The President is both Head of State and Head of Government.

• The unicameral Parliament elects the President, who remains accountable to it.

• There are no political parties; Members of Parliament contest as independents.

Economy: from phosphate wealth to vulnerability

• Phosphate mining once made the country one of the wealthiest in the world on a per-capita basis.

• The depletion of phosphate reserves created major economic difficulties.

• Agriculture, fishing, manufacturing and tourism make only modest contributions.

• Commercial fishing licences issued within its EEZ are another source of revenue.

Pseudolaguvia khairii

Biodiversity | New freshwater species

WHY IN NEWS:

Researchers discovered a new freshwater catfish species, Pseudolaguvia khairii, in Odisha.

IN ONE LINE:

It is a small hillstream catfish from the Budhabalanga River, identified by a unique fleshy projection at the base of its dorsal fin.

Discovery and naming

• Discovery site: Budhabalanga River, Mayurbhanj district, Odisha.

• The species was named after Khairi, the legendary tigress associated with wildlife conservation and a unique human-animal bond in Odisha.

Taxonomic identity

• Genus: Pseudolaguvia.

• Group: Small hillstream catfishes.

Members of the genus occur in India, Bangladesh, Nepal and Myanmar. They inhabit clear and fast-flowing hill streams and rivers.

What makes the species distinct?

• It is a small freshwater catfish measuring only a few centimetres in length.

• Its defining feature is a fleshy protuberance at the base of the dorsal fin.

• This feature had not previously been recorded in any known species of the genus Pseudolaguvia.

Habitat

The species is adapted to clear, fast-flowing freshwater rivers and hillstream ecosystems with continuously moving water.

Pseudecheneis likimroensis

Biodiversity | Hillstream adaptation

WHY IN NEWS:

A new catfish species, Pseudecheneis likimroensis, was discovered in the Likimro River of Nagaland and described in the Journal of Ichthyology.

IN ONE LINE: This fast-water adapted catfish uses a flattened body and specialised adhesive organs to survive in the strong currents of Nagaland's hill streams.

Discovery profile

• Named after the Likimro River, where it was first collected.

• Local name: Nupedro.

• Location: Likimro River, Kiphire district, Nagaland, near the India-Myanmar border.

• Identified by researchers from Kohima Science College and the Zoological Survey of India.

Adaptations to fast-flowing water

The species belongs to the genus Pseudecheneis, a group of rheophilic catfishes. "Rheophilic" refers to organisms adapted to flowing water.

• Its body is flattened from top to bottom, helping it remain stable in swift currents.

• It has specialised adhesive organs with ridges separated by grooves, enabling it to cling to rocks.

• It is carnivorous and feeds on insects, larvae and other organisms attached to rocks.

Size

• Holotype: About 11.53 cm.

• Largest recorded specimen: About 13.19 cm.

Likimro River: remember the river system

• A fast-flowing mountain river with rich freshwater biodiversity.

• Flows through eastern Kiphire district in Nagaland.

• Originates near Mount Saramati, the highest peak in Nagaland.

• It is a tributary of the Tizu River.

• The Tizu ultimately joins the Chindwin-Irrawaddy river system in Myanmar.

• Clear water, boulders and rocky stretches make the river suitable for hillstream fishes.

Leptospirosis

Health | Monsoon-related zoonotic disease

WHY IN NEWS:

Cases of leptospirosis generally rise during the monsoon, leading health authorities to stress preventive measures against this water-borne zoonotic disease.

IN ONE LINE: Leptospirosis is a bacterial disease transmitted mainly through water or soil contaminated by the urine of infected animals.

What is leptospirosis?

• A tropical zoonotic bacterial disease affecting humans and animals.

• Common names: Rat Fever and Flood Fever.

• Causative bacterium: Leptospira.

• The bacteria can survive in contaminated water and moist soil.

How does it spread?

The disease spreads through the urine of infected animals, especially rodents, cattle, dogs and cats.

• During the monsoon, infected urine and animal waste can mix with floodwater and mud.

• The bacteria enter the human body through cuts, abrasions, cracked skin or the mucous membranes of the eyes, nose and mouth.

• Person-to-person transmission is rare.

Symptoms

• High fever

• Severe headache

• Chills

• Muscle pain

• Vomiting

• Jaundice

• Red eyes

• Abdominal pain

• Diarrhoea

• Skin rashes

Possible complications

Without timely treatment, the infection may cause kidney damage, meningitis, liver failure, respiratory distress and multi-organ failure. Severe cases can result in death.

Treatment

• Antibiotics are the primary treatment.

• Severe cases may require intravenous antibiotics and supportive hospital care.

Prevention during the monsoon

• Wear waterproof footwear while walking through floodwater.

• Wash and dry the feet properly after exposure.

• Clean and cover cuts or wounds promptly.

• Maintain sanitation and control rodent populations.

• Drink safe and clean water, particularly after floods.

• Avoid direct contact with potentially contaminated water wherever possible.

Situation in India

Kerala has reported leptospirosis since 1989. The disease has remained endemic in the State for more than three decades and is among its communicable diseases with the highest mortality.
