“…This area is characterised by a high diversity of species and natural communities due to the pronounced diversity of climatic, altitude and soil conditions, as well as its location at the junction of various biogeographic regions in Asia. The terrestrial mammal fauna of the Primorsky Krai includes more than 80 species, including 18 species of carnivorans (Pavlinov & Lissovsky, 2012;Darman et al, 2019).…”

Nematodes of the genus Trichinella cause trichinosis, which is a zoonotic disease of humans, wild and domestic animals. In the Russian Far East, trichinosis has a natural focal character. Carnivorans (Carnivora), living in natural ecosystems including Protected Areas, are the main hosts of Trichinella. The peculiarities of Trichinella circulation in natural environment and the parasite prevalence in wild animals of different species remain poorly understood as well as the species composition of the Trichinella genus in the studied region. Muscle samples were obtained from 731 specimens belonging to 14 species and four families (Mustelidae, Ursidae, Felidae, and Canidae) in Primorsky Krai (Russia) in 2010-2020 and examined on Trichinella. The parasites were found in 124 specimens belonging to 11 species. The highest Trichinella prevalence was observed in Vulpes vulpes (64%), Ursus arctos (57%), and Lynx lynx (50%). A relatively high ratio of infected animals (30-50%) was found in Nyctereutes procyonoides, Ursus thibetanus, and Prionailurus bengalensis. The parasite prevalence was relatively low in the representatives of the Mustelidae family. Three species of the genus Trichinella (T. nativa, T. spiralis, and T. pseudospiralis) were found for carnivorans inhabiting the study area. Trichinella nativa was found the most frequently in natural ecosystems. Trichinella pseudospiralis was discovered for the first time both for P. bengalensis and for the area of the Primorsky Krai. The Carnivora ecology contributes to a high risk of infection by Trichinella species. The parasite prevalence was high in the species that combined different feeding habits, i.e. they acted as predators, scavengers and cannibals. A relatively long life expectancy also contributed to a higher risk of infection. A relatively high parasite prevalence of Trichinella in wild animals in the Primorsky Krai was caused by the high biological diversity of carnivorans. Our results are important for understanding the trichinosis circulation in natural communities and the possibility of human infestation. These data are also important for managing the carnivorans' populations in the Russian Far East. The issues of nature conservation in regard to the trichinosis circulation are also important for threatened animals, including Panthera tigris altaica.

“…Although there are no specific occurrence data or population descriptions of water deer in North Korea, combining the available references, it can be assumed that water deer are distributed in suitable habitats in both western and eastern North Korea [3, 6]. However, since 2019, water deer have been frequently reported in the boundary area between China, Russia, and the Democratic People’s Republic of Korea, where there are no earlier formal records of this species [7]. In the newly occupied areas in the lower Tumen River basin in China and in the Russian Far East, there are still many wild areas with relatively low human impact.…”

Global changes may direct species expansion away from their current range. When such an expansion occurs, and a species colonizes a new region, it is important to monitor the habitat used by the species and use the information for updated management strategies. Water deer is listed as Vulnerable species in IUCN Red List and restricted to east central China and the Korean Peninsula. Since 2017 water deer has expanded its range towards northeast China and the Russian Far East. Our research focuses on data collected in northeast China and the Russian Far East during 2017-2021, with the purpose of providing support for a better understanding of habitat use and provide conservation suggestions. We used MaxEnt to model species niche and distribution and predict habitat suitability for water deer and applied the circuitscape to determine possible dispersal routes for the species. There is good quality habitat for water deer in the boundary area of the Yalu and Tumen River estuaries between China, North Korea, and the Russian Far East, as well as the east and west regions of the Korean Peninsula. Elevation, distance to cropland and water sources, and presence of wetlands were the variables that positively contributed to modelling the suitable habitats. Two possible dispersal routes were determined using the circuit theory, one was across the area from North Korea to the downstream Tumen transboundary region, and the other was across North Korea to the boundary region in China and along the tiger national park in northern China. A series of protected areas in North Korea, China, and Russia may support the dispersal of water deer. The establishment of a Northeast Asia landscape conservation network would help establish monitoring and conservation planning at a broad scale, and this study provides an example for the need for such a network

“…But by the middle of the last century, only two habitats remainedthe Chinese water deer (H. i. Inermis) in the Shanghai region in southern China with a population of no more than 10,000 individuals [13], and the Korean water deer (H. i. Argyropus) on border of South and North Korea [12]. There is information about the transitions of water deer from North Korea to China [3]. In 2019, in the Land of the Leopard National Park, a camera trap recorded a "swamp musk deer", which, according to experts, turned out to be a water deer [3].…”

“…There is information about the transitions of water deer from North Korea to China [3]. In 2019, in the Land of the Leopard National Park, a camera trap recorded a "swamp musk deer", which, according to experts, turned out to be a water deer [3]. This small deer of an unusual appearance simultaneously resembles a Siberian roe deer (Capreolus pygargus Pallas 1771) and a musk deer (Moschus moschiferus L., 1758).…”
