Question: East Siberian Laika and Rastreador Brasileiro, are which kind of animal?
Context: The East Siberian Railway ("Восточно-Сибирская железная дорога" ) is a railway in Russia (a branch of the Russian Railways and a part of the Trans-Siberian Railway), which runs across Irkutsk Oblast, Chita Oblast, Buryatia, and Yakutia.  The railway administration is located in Irkutsk.  The East Siberian Railway borders with the Krasnoyarsk Railway (railway station of Yurty), Trans-Baikal Railway (railway station of Petrovsky Zavod), and Baikal Amur Mainline (railway station of Lena-Vostochnaya).  To the south, the East Siberian Railway runs close to the Russo-Mongolian border (railway station of Naushki).  As of 2008, the total working length of the East Siberian Railway was 3848.1 km ; number of employees – 46,233 (61,418 in 2005); net weight hauled – 76 million tonnes (75.934 million in 2005); long-distance passenger traffic – 3.6 million people (4.838 million in 2005); suburban traffic – 29 million people (26.225 million in 2005).  Annual cargo turnover is 278 million tonnes. The New Siberian Islands (Russian: Новосиби́рские острова , "Novosibirskiye Ostrova" ; Yakut: Саҥа Сибиир арыылара, "Sanga Sibiir aryylara" ) are an archipelago in the Extreme North of Russia, to the North of the East Siberian coast between the Laptev Sea and the East Siberian Sea north of the Sakha (Yakutia) Republic. Kem (Russian: Кемь ) is a river in Siberian in Russian Krasnoyarsk Krai.  It is a left bank tributary of the Yenisei River.  The name of the River Kem comes from the ancient word "kem" or "hem" that has a meaning of "great river".  This toponymy is very popular and widespread from Siberia up to the Karelia and Finland.  The river flows across the West Siberian Plain through the districts of Bolshemurtinsky, Kazachinsky, Pirovsky, and Yeniseysky District before discharging into the Yenisei River close to the town of Yeniseysk at 2045 kilometers before the mouth.  The River Kem is 356 kilometres (221 miles) long.  The Kem River basin covers a total area of 8,940 square kilometres (3,452 square miles).  The most important tributaries of the River Kem are Tiya (Russian: Тыя ) at the 97 kilometer from the mouth and Belaya (Russian: Белая ) at the 115 kilometer from the mouth.  Both major tributaries are on the left side.  Source of the River Kem is located in Bolshemurtinsky District where it originate as a small creek in the East Siberian taiga.  Due to the tributary rivers, towards the mouth river reaches 45 meters of width. The Rastreador Brasileiro (in English, Brazilian Tracker) is a large breed of dog from Brazil, first recognised by the Fédération Cynologique Internationale in 1967, but an outbreak of disease, compounded by an overdose of insecticide, wiped out the breed's entire breeding stock.  The FCI and the Brazilian Kennel Club (Confederação Brasileira de Cinofilia) then declared the breed extinct in 1973 and delisted it.  Since then, efforts have been made to re-create the breed.  The Rastreador Brasileiro is a hunting dog of the scenthound type.  The breed is also known by the names "Urrador" (for its hunting cry) or "Urrador Americano", in reference to the American (U.S.) coonhounds in its background. The East Siberian Oblast was an early oblast of the Russian Soviet Federative Socialist Republic, which existed from December 5, 1936 to September 26, 1937.  It was created when the East Siberian Krai was divided into the East Siberian Oblast and the Buryat Autonomous Soviet Socialist Republic in 1936 and ceased to exist after being split into the Irkutsk Oblast and the Chita Oblast in 1937. The East Siberian Laika (Vostotchno-Sibirskaia Laika) is a Russian breed of dog of spitz type, a hunting dog originating in parts of Siberia east of the Yenisei River. The Siberian sturgeon ("Acipenser baerii") is a species of sturgeon in the Acipenseridae family.  It is most present in all of the major Siberian river basins that drain northward into the Kara, Laptev and East Siberian Seas, including the Ob, Yenisei (which drains Lake Baikal via the Angara River) Lena, and Kolyma Rivers.  It is also found in Kazakhstan and China in the Irtysh River, a major tributary of the Ob. The Vega gull, East Siberian gull, or East Siberian herring gull ("Larus vegae") is a large gull of the herring gull/lesser black-backed gull complex which breeds in North-east Asia.  Its classification is still controversial and uncertain.  It is variously treated as a separate species, as a subspecies of American herring gull ("L. smithsonianus") or included with both the American herring gull and European herring gull in "L. argentatus".  The Mongolian gull, "Larus mongolicus", has previously been regarded as a subspecies of the Caspian gull ("L. cachinnans") but is now sometimes lumped with the Vega gull. The Siberian lynx ("Lynx lynx wrangeli"), also known as East Siberian lynx, is a subspecies of Eurasian lynx living in the Russian Far East.  It lives in the Stanovoy Range and east of the Yenisei River.  There are 5,890 mature individuals in the Russian Far East as of 2013.  Prey include the Siberian roe deer. The West Siberian Laika or "WSL", is a breed of hunting dog and a breed of spitz type.  Russian publications indicate that the term West Siberian Laika loosely applied to hunting dogs originating with the Mansi and Khanty people in Ural and West Siberia, but there were no standards or registrations of WSL as such until 1930.  Then WWll disrupted it for a while, but "systematic breeding with registrations" resumed after the war ended, in 1946.  This was the time the breed began taking modern shape.  Before that hunters only knew of Mansi Laika and Khanty Laika.  In early 1960 many hunters in Ural still preferred the term Mansi Laika, when speaking of West Siberian Laika.  In Russian language, the term Laika originated from the word "layat" that means to bark.  The word Laika simply means "barker".  Any hunting Laika is a bark pointer (pointing at animal of interest by barking and staying with the animal ).  It is a versatile dog depending on use and environment, but in certain parts of the country they have become more specialized.
