Olive Ridley Lepidochelys olivacea smallest sea turtle performs arribada mass nesting where thousands females simultaneously nest on specific beaches. Odisha coast supports largest global rookeries at Gahirmatha Marine Sanctuary, Rushikulya river mouth, and Devi River mouth. Arribada occurs December-March driven by wind, lunar cycle. Gahirmatha recorded over half million nests single season. Turtles require undisturbed sandy beaches above high tide, low artificial lighting. Odisha government enforces trawler-free zone 20 km, TED turtle excluder devices, Indian Coast Guard Operation Olivia prot

Ganges river dolphin Platanista gangetica gangetica, obligate freshwater cetacean, occurs in main channels and tributaries of Ganga-Brahmaputra-Meghna system across Gangetic Plains biogeographic zone from Himalayan foothills to Sundarbans. Functionally blind due to muddy waters, navigates by echolocation clicks, preying on fish, shrimps. Population estimated below 3500, threatened by barrages fragmenting populations, entanglement in fishing nets, pollution and noise. India's National Aquatic Animal since 2009, protected under Wildlife Protection Act Schedule I, Vikramshila sanctuary in Bihar d

Captive breeding programmes systematically breed threatened species in controlled environments such as zoos, breeding centers, hatcheries to increase population, maintain genetic heterozygosity, and minimize inbreeding through pedigree management and studbooks. Offspring undergo acclimatization, behavioral enrichment, health screening before reintroduction into restored habitats after threat mitigation. Indian examples include gharial breeding at Chambal, pygmy hog at Basistha Assam, snow leopard at Padmaja Naidu Himalayan Park. Goal is preventing imminent extinction and ultimate reinforcement

National Chambal Sanctuary, established 1979 along Chambal River crossing Rajasthan, Madhya Pradesh, and Uttar Pradesh over 5400 km², is India's only tri-state protected riverine tract dedicated to aquatic fauna conservation. Its clear waters, sandy banks, and deep pools provide prime breeding habitat for gharial Gavialis gangeticus with distinctive long narrow snout specialized for fish catching, critically endangered with less than 1000 adults wild. Sanctuary also shelters Ganges dolphin, red-crowned roof turtle, and migratory birds. Field identification relies on this character, making it e

Bishnoi community inhabiting Thar desert of Rajasthan, Punjab, and Haryana follows 29 principles prescribed by Guru Jambheshwar in 1485, emphasizing protection of trees and animals. Khejrali massacre 1730 where 363 Bishnois sacrificed lives protecting khejri trees symbolizes ethic. Bishnois protect blackbuck Antilope cervicapra, chinkara, peafowl, allowing them to graze near villages, actively guarding against poachers, providing water. Government awards like Amrita Devi Bishnoi Wildlife Protection Award honor contributions; court judgments cite Bishnoi vigilance. Knowledge of this distributio

“Isolated small islands” for the highest risk of extinction is usually found on. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. At equilibrium, species identities can continue to turn over even when richness is approximately stable. The model predicts a balance of rates, not an absence of colonization or extinction. The remaining alternatives—“Isolated large islands”, “Islands close to the mainland”, “Large continental islands”—refer to different states, processes, or scales and therefore do not

“High variability in population size” for which of the following is most vulnerable to extinction. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. The mechanism should be evaluated across both local and global scales. Local disappearance can be reversed by recolonization, whereas global extinction is irreversible and requires the loss of every surviving population. The remaining alternatives—“Wide geographic range”, “Low trophic level”, “High dispersal ability”—refer to different states, processes
