Workforce develops a novel and environment friendly technique for monitoring Asian otters

Southeast Asia is a melting pot of otters which might be very troublesome to watch within the wild. A analysis crew has developed and examined a novel, correct, and reasonably priced DNA-based technique to reliably determine three endemic Asian otter species. Their outcomes are reported in a paper revealed as we speak in Ecology and Evolution.

The protocol developed by the crew of South Asian researchers from the Malaysian Nature Society, Sunway College, Division of Wildlife and Nationwide Parks (PERHILITAN), Peninsular Malaysia, Martin Luther College Halle-Wittenberg, and the German Centre for Integrative Biodiversity Analysis (iDiv) will assist in monitoring and conservation of threatened otter species in Asia. Their analysis can even spotlight the significance and wish of cost-effective and replicable methods to advance biodiversity monitoring in extremely biodiverse but underrepresented components of the world.

Correct and efficient monitoring is crucial to advance the scientific information and standing of biodiversity. Southeast Asia, a worldwide biodiversity hotspot, can be uncovered to a number of human-induced threats which might be pushing the species to peril. 4 otter species co-occur on this a part of the world, and never a lot is thought concerning the distribution and inhabitants measurement of those species. They’re threatened by habitat loss, unlawful wildlife commerce, air pollution and degradation of aquatic habitat, human-otter battle, and local weather change. The quickly rising Asian economic system and related infrastructural improvement, reminiscent of roads, have gotten one other reason behind otter mortality.

Otters, sentinels of freshwater ecosystems, are troublesome to differentiate and monitor in wild attributable to their elusive nature and similarities in look amongst species. This requires a complicated method that isn’t solely correct and replicable, but in addition reasonably priced to wildlife researchers of the area, who usually work with little analysis funding.

With this goal, the crew developed a set of PCR-RFLP evaluation protocols that can be environment friendly in evaluation of DNA sourced from non-invasive samples reminiscent of feces (spraints in case of otters). They examined this protocol on recognized reference samples, and additional on spraint samples collected from otter habitat in Malaysia. Their method has excessive amplification success (97%) for dependable and environment friendly species identification of three Asian otter species. They anticipate that it’ll assist in monitoring the standing of otter populations in South and Southeast Asia.
