Which country is the plant, which is attacked by a parasite that shares the same name as the largest extant species in the deer family, located?
Russia
Moose
The moose (North America) or elk (Eurasia), "Alces alces", is the largest extant species in the deer family.
 Moose are distinguished by the broad, flat (or "palmate") antlers of the males; other members of the family have antlers with a dendritic ("twig-like") configuration.
 Moose typically inhabit boreal forests and temperate broadleaf and mixed forests of the Northern Hemisphere in temperate to subarctic climates. Hunting and other human activities have caused a reduction in the size of the moose's range over time.
 Moose have been reintroduced to some of their former habitats.
 Currently, most moose are found in Canada, Alaska, New England, Fennoscandia, Baltic States, and Russia.
 Their diet consists of both terrestrial and aquatic vegetation.
 The most common moose predators are the gray wolf along with bears and humans. Unlike most other deer species, moose are solitary animals and do not form herds.
 Although generally slow-moving and sedentary, moose can become aggressive and move quickly if angered or startled.
 Their mating season in the autumn features energetic fights between males competing for a female.
Elaeophora abramovi
Elaeophora abramovi is a nematode parasite found in the hepatic arteries of the Moose ("Alces alces") in Russia.
Two-toed amphiuma
The two-toed amphiuma ("Amphiuma means") is a snake-like salamander found chiefly in the southeastern United States.
 It is commonly, but incorrectly, called "congo snake", "conger eel" or the "blind eel".
 One of the largest extant species of amphibians in the world, they can grow from 39 to in mass and from 34.8 to in length.
 They have four vestigial legs that end in two or three toes which are virtually useless, and eyes without lids.
 They are blue-black in color.
 They feed on small fish, crawfish, insect larvae, and even small snakes; they are harmless to humans when left alone, but when disturbed, they can deliver a tough bite, which may lead to a severe infection.
 Unlike other salamanders, which are mute, "A. means" gives a clear whistle when disturbed. Elk
The elk, or wapiti ("Cervus canadensis"), is one of the largest species within the deer family, Cervidae, in the world, and one of the largest land mammals in North America and Eastern Asia.
 This animal should not be confused with the still larger moose ("Alces alces") to which the name "elk" applies in British English and in reference to populations in Eurasia.
 Apart from the moose, the only other member of the deer family to rival the elk in size is the south Asian sambar ("Rusa unicolor"). Trumpeter swan
The trumpeter swan ("Cygnus buccinator") is a species of swan found in North America.
 The heaviest living bird native to North America, it is also the largest extant species of waterfowl with a wingspan that may exceed 10 ft .
 It is the American counterpart and a close relative of the whooper swan ("Cygnus cygnus") of Eurasia, and even has been considered the same species by some authorities.
 By 1933, fewer than 70 wild trumpeters were known to exist, and extinction seemed imminent, until aerial surveys discovered a Pacific population of several thousand trumpeters around Alaska's Copper River.
 Careful reintroductions by wildlife agencies and the Trumpeter Swan Society gradually restored the North American wild population to over 46,000 birds by 2010. Musk deer
Musk deer can refer to any one, or all seven, of the species that make up Moschus, the only extant genus of the family Moschidae.
 The musk deer family differs from cervids, or true deer, by lacking antlers and facial glands and by possessing only a single pair of teats, a gallbladder, a caudal gland, a pair of tusk-like teeth and—of particular economic importance to humans—a musk gland. Deer botfly
The name deer botfly (also deer nose bot) refers to any species in the genus Cephenemyia (sometimes misspelled as "Cephenomyia" or "Cephenemya"), within the family Oestridae.
 They are large, gray-brown flies, often very accurate mimics of bumblebees.
 They attack chiefly the nostrils and pharyngeal cavity of members of the deer family.
 The larva of "Cephenemyia auribarbis", infesting the stag, is called a stagworm.
 The genus name comes from the Greek "kēphēn", drone bee, and "myia", fly. Chevrotain
Chevrotains, also known as mouse-deer, are small ungulates that make up the family Tragulidae, the only members of the infraorder Tragulina.
 The ten extant species are in three genera, but several species also are known only from fossils.
 The extant species are found in forests in South and Southeast Asia, with a single species in the rainforests of Central and West Africa.
 They are solitary or live in pairs, and feed almost exclusively on plant material.
 Depending on exact species, the Asian species weigh between 0.7 and , and include the smallest ungulates in the world.
 The African chevrotain is considerably larger at 7 - . Vulturine guineafowl
The vulturine guineafowl ("Acryllium vulturinum") is the largest extant species of guineafowl.
 Systematically, it is only distantly related to other guineafowl genera.
 Its closest living relative, the white breasted guineafowl, "Agelastes meleagrides" inhabit primary forests in Central Africa.
 It is a member of the bird family Numididae, and is the only member of the genus "Acryllium".
 It is a resident breeder in northeast Africa, from southern Ethiopia through Kenya and just into northern Tanzania. White rhinoceros
The white rhinoceros or square-lipped rhinoceros ("Ceratotherium simum") is the largest extant species of rhinoceros.
 It has a wide mouth used for grazing and is the most social of all rhino species.
 The white rhinoceros consists of two subspecies: the southern white rhinoceros, with an estimated 19,682–21,077 wild-living animals in the year 2015, and the much rarer northern white rhinoceros.
 The northern subspecies had very few remaining, with only three confirmed individuals left in 2015 (two females; Fatu, 15 and Najin, 25: and one male; Sudan, 42), all in captivity.
