Losing its ground: A case study of fast declining populations of a ‘least-concern’ species, the bonnet macaque (Macaca radiata)

摘要: The populations of many species that are widespread and commensal with humans have been drastically declining during the past few decades, but little attention has paid to their conservation. Here, we report status bonnet macaque, a is considered ‘least-concern’ for We show widely ranging rhesus macaque expanding its range into distributional endemic only southern India. Bonnet macaques very low abundance in forests all types indicating it not typically forest dwelling species. traditionally preferred habitats Hindu temples/ tourist spots our data reveal nearly 50% population disappeared from such previously occupied spots. Another habitat roadsides abundant Ficus trees adjoining croplands. found between 2003 2015, changed where vegetation replaced barren lands urbanization. Consequently, declined by more than 65% over 25 years, 2015 alone. We, therefore, conclude this actually facing serious conservation challenges. also identify places as small hillocks natural temples/tourist which likely remain stable thus can serve ‘bonnet reserves’. Since shares traits several other ‘low-risk’ species, model development long-term strategies most
