Plants are essential sources of food, medicine, shelter, fuel, feed, and forage, and provide a wide range of additional ecosystem and cultural services to humanity. In recognition of the tremendous value of useful plants and of the increasing threats to their persistence, international agreements including the Convention on Biological

TheVulnerable bumphead parrotfishBolbometopon muricatum, a highly prized fishery resource worldwide, has experienced population declines throughout its geographical range. There is limited knowledge of the distribution and abundance of, and threats to, this fish in Indian waters, particularly for the Andaman and Nicobar Islands.

Most large carnivore populations currently occur in heterogeneous landscapes, with source populations embedded in a matrix of human-dominated habitats. Understanding changes in distribution of endangered carnivores is critical for prioritizing and implementing conservation strategies.

Identifying the species that are at risk of local extinction in highly diverse ecosystems is a big challenge for conservation science. Assessments of species status are costly and difficult to implement in developing countries with diverse ecosystems due to a lack of species-specific surveys, species-specific data, and other
