Surveys conducted by NUS researchers led by Dr <\/span><span>Daniel NG Jia Jun and Prof Darren YEO Chong Jinn from the Department of Biological Sciences in NUS <\/span><span>revealed that the species had declined in its original locality within a nature reserve, but continued to thrive in a few unprotected sites outside it. <\/span><\/p>\n<p><span>The decline was believed to be associated with stream acidification, which may be the first documented example of such an effect on a tropical freshwater species. As its occurrence in a protected area does not necessarily guarantee its survival (i.e. it is insufficient to simply leave \u201cgood enough\u201d alone), long-term monitoring together with other conservation measures are also needed to ensure that this unique species does not become globally extinct. Of particular importance are onging collaborative conservation efforts between NUS and the National Parks Board, Singapore (NParks) and Wildlife Reserves, Singapore (WRS), which ensure an effective, comprehensive, multi-pronged approach to safeguarding the species. One recent product of their combined efforts (working with the International Union for Conservation of Nature, IUCN), is the publication of a detailed conservation strategy for the Singapore freshwater crab\u2014the first time this has been done for a single invertebrate species\u2014that provides a structured framework and roadmap for the conservation of the species.<\/span><\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" alt=\"darren\" src=\"https:\/\/www.science.nus.edu.sg\/wp-content\/uploads\/2019\/11\/darren.jpg\" width=\"591\" height=\"349\" \/><\/p>\n<p><span>The critically endangered Singapore freshwater crab (<i>Johora singaporensis<\/i>) hiding among leaf litter in a hill stream.
