Practice question

Keibul Lamjao National Park in Manipur, declared 1977 covering 40 km² of Loktak Lake, is world's only floating national park built on phumdis. Unique habitat supports Sangai Rucervus eldii eldii, critically endangered brow-antlered deer endemic to Manipur, state animal, with adapted splayed hooves balancing on floating biomass. Estimated population below 260, dependent on phumdi thickness maintained by natural water level fluctuations of Loktak. Phumdi removal, hydropower dam Ithai altering hydrology, and poaching threaten delicate equilibrium. Examinations emphasize this concept because it underpins correct interpretation of phylogenetic relationships and evolutionary systematics.
