Researchers have discovered a new frog species named Ingerana occidens, commonly known as the western trickle frog, in the Garo and Khasi Hills of Meghalaya. Genetic analysis reveals an 18% divergence from its northern counterparts across the Brahmaputra River. This discovery underscores the rich, endemic biodiversity of Northeast India's canopy-covered streams and highlights the urgent need to protect these fragile forest ecosystems.
“Scientists exploring the forests in Northeast India found a tiny frog that no one had ever recorded before. They named it the western trickle frog. Finding new animals is exciting but it also serves as a warning that we must protect these forests before these unknown creatures are wiped out by pollution or logging.”

Endemism refers to species being unique to a defined geographic location, such as an island or a specific mountain range, and not naturally found anywhere else. The Garo and Khasi hills act as isolated ecological niches due to complex topography and rivers like the Brahmaputra, driving unique evolutionary pathways (speciation) over millions of years.
A new species named 'Ingerana occidens', recently discovered in the Garo and Khasi Hills, belongs to which of the following categories of fauna?
Consider the following hills: 1. Garo 2. Khasi 3. Jaintia. These hills, known for their high biodiversity, are a geographical extension of which of the following structures?
The discovery of new species in Northeast India highlights the region's status as a biodiversity hotspot. Discuss the major anthropogenic threats to this biodiversity and suggest conservation strategies.
