英文摘要	The dhole ( Cuon alpinus ), a mountain canid species that once lived throughout north, south, and southeast Asia ([ 1 ][1]), is endangered worldwide ([ 2 ][2], [ 3 ][3]). Now found primarily in the forests, shrub belts, and grasslands of southeastern China ([ 4 ][4]), the dhole population includes only 949 to 2215 individuals with reproductive capacity ([ 3 ][3]). Although there have been positive steps toward the species' conservation, more must be done to prevent its extinction. There are many reasons for the catastrophic decrease in the number of dholes ([ 5 ][5]). In the past few decades, human production and activities have occupied large areas of the dhole's original habitats ([ 6 ][6]). As humans have expanded into their habitats, dholes—which form groups to hunt large herbivores—have also preyed on livestock, causing conflicts ([ 6 ][6]). In response, humans have begun to hunt dholes ([ 6 ][6]), further decreasing the species' population numbers. The dhole, which by preying on herbivores indirectly limits consumption of plants, is important to maintaining the structural and functional integrity of the ecosystem ([ 7 ][7]). However, there is very little protection of, or scientific research on, the species ([ 8 ][8]). On 5 February, the Chinese government upgraded dholes from Class II to Class I, the highest level of protected species, on the National Key Protected Species List ([ 9 ][9]). This classification change, although a good first step, is insufficient. We must also raise awareness about the importance of protecting dholes to discourage humans from destroying their habitats and killing them during conflicts or hunting. Governments, including China's ([ 10 ][10]), must immediately implement the strictest possible wildlife control measures. In addition, studies on the species' feeding habits, population dynamics, habitat selection, reproductive ecology, and genetic diversity should be conducted. Once such research yields results, we will be able to implement targeted conservation measures both in the wild and in captivity. 1. [↵][11]1. X. Wu et al ., Appl. Microbiol.
