European bison#Etymology

The ancient Greeks and ancient Romans were the first to name bison as such; the 2nd-century AD authors Pausanias and Oppian referred to them as {{Langx|grc-x-hellen|βίσων|translit=bisōn|label=none}}.{{Cite book |last= |first= |url=https://www.oed.com/view/Entry/19486 |title=bison, n. |work= |publisher= |year=2011 |isbn= |edition=online 2nd |location= |pages= |access-date=11 January 2021 |via=Oxford English Dictionary |orig-year=1989}} Earlier, in the 4th century BC, during the Hellenistic period, Aristotle referred to bison as {{Langx|grc-x-hellen|βόνασος|translit=bónasos|label=none}}. He also noted that the Paeonians called it μόναπος (monapos).Αριστοτέλης 4th century BC: Των περί τα ζώα ιστοριών. Claudius Aelianus, writing in the late 2nd or early 3rd centuries AD, also referred to the species as {{Langx|grc-x-hellen|βόνασος|label=none}}, and both Pliny the Elder's Natural History and Gaius Julius Solinus used {{Langx|la|bĭson}} and {{Langx|la|bonāsus|label=none}}. Both Martial and Seneca the Younger mention {{Langx|la|bison|label=none}} ({{Abbr|pl|plural}}. {{Langx|la|bisontes|label=none}}). Later Latin spellings of the term included {{Langx|la|visontes|label=none}}, {{Langx|la|vesontes|label=none}}, and {{Langx|la|bissontes|label=none}}.

John Trevisa is the earliest author cited by the Oxford English Dictionary as using, in his 1398 translation of Bartholomeus Anglicus's De proprietatibus rerum, the Latin plural {{Langx|la|bisontes|label=none}} in English, as "bysontes" ({{Langx|enm|byſontes}} and {{Langx|enm|bysountes|label=none}}). Philemon Holland's 1601 translation of Pliny's Natural History, referred to "bisontes". The marginalia of the King James Version gives "bison" as a gloss for the Biblical animal called the "pygarg" mentioned in the Book of Deuteronomy. Randle Cotgrave's 1611 French–English dictionary notes that {{Langx|fr|bison|label=none}} was already in use in French, and it may have influenced the adoption of the word into English; alternatively, it may have been borrowed directly from Latin. John Minsheu's 1617 lexicon, Ductor in linguas, gives a definition for Bíson in {{Langx|en-emodeng|"a wilde oxe, great eied, broad-faced, that will neuer be tamed"}}.

In the 18th century the name of the European animal was applied to the closely related American bison (initially in Latin in 1693, by John Ray) and the Indian bison (the gaur, Bos gaurus). Historically, the word was also applied to Indian domestic cattle, the zebu (B. indicus or B. primigenius indicus). Because of the scarcity of the European bison, the word 'bison' was most familiar in relation to the American species.

By the time of the adoption of 'bison' into Early Modern English, the early medieval English name for the species had long been obsolete: the {{Langx|ang|wesend}} had descended from {{langx|gem-x-proto|*wisand}}, {{langx|gem-x-proto|wisund|label=none}} and was related to {{langx|non|vísundr}}. The word 'wisent' was then borrowed in the 19th century from modern {{langx|de|Wisent}} [{{IPA|ˈviːzɛnt}}], itself related to {{langx|goh|wisunt}}, {{langx|goh|wisent|label=none}}, {{langx|goh|wisint|label=none}}, and to {{Langx|gmh|wisant}}, {{Langx|gmh|wisent|label=none}}, {{Langx|gmh|wisen|label=none}}, and ultimately, like the Old English name, from Proto-Germanic.{{Cite book|last=|first=|chapter-url=https://www.oed.com/view/Entry/229509|chapter=wisent, n.|title=Oxford English Dictionary|publisher=|year=1989|isbn=|edition=online 2nd|location=|pages=|access-date=11 January 2021|orig-year=1928|archive-date=28 December 2021|archive-url=https://web.archive.org/web/20211228030210/https://www.oed.com/start;jsessionid=564822A79DF48AD419DE5B2E2B82A0F2?authRejection=true&url=%2Fview%2FEntry%2F229509|url-status=live}}

The word 'zubr' in English is a borrowing from {{langx|pl|żubr}} {{IPAc-pl|ʐ|u|b|r}}, previously also used to denote one race of the European bison.{{cite journal|last1=Weissenborn|first1=W.|date=1838|title=On the Influence of Man in modifying the Zoological features of the Globe; with Statistical Accounts respecting a few of the more important species of Animals|journal=The Magazine of Natural History|volume=2}}{{cite journal|last1=Wilson|first1=James|date=1831|title=Essay III: On the origin and natural history of the domestic ox, and its allied species|journal=Journal of Agriculture|volume=2}} The Polish żubr is similar to the word for the European bison in other modern Slavic languages, such as {{langx|hsb|žubr|label=none}} in Upper Sorbian; {{langx|uk|зубр|translit=zubr|label=none}} or {{langx|uk|бізон|translit=bizon|label=none}} in Ukrainian; {{langx|be|зубр|translit=zubr|label=none}} (or {{langx|be|зубар|translit=zubar|label=none}}) or {{langx|be|бізон|translit=bizon|label=none}} in Belarusian; and {{langx|ru|зубр|translit=zubr|label=none}} in Russian. The noun for the European bison in all living Slavonic tongues is thought to be derived from Proto-Slavic: *zǫbrъ ~ *izǫbrъ, which itself possibly comes from Proto-Indo-European: *ǵómbʰ- for tooth, horn or peg.{{cite journal |last1=Jagodziński |first1=Grzegorz |date=2008 |title=Nieindoeuropejskie słownictwo w germańskim |url=http://www.eioba.pl/a/1vmf/nieindoeuropejskie-slownictwo-w-germanskim |url-status=live |journal=Nieindoeuropejskie słownictwo w germańskim |archive-url=https://web.archive.org/web/20191210103705/http://www.eioba.pl/a/1vmf/nieindoeuropejskie-slownictwo-w-germanskim |archive-date=10 December 2019 |access-date=30 November 2019}} In the Baltic countries of Lithuania and Latvia, where some bison populations persist as well, the animal is known as {{langx|lv|stumbras|label=none}} (plural: strumbrai) in Lithuanian and {{langx|lt|sumbrs|label=none}} (plural: sumbri) in Latvian, respectively.

The European bison makes a variety of vocalisations depending on its mood and behaviour, but when anxious, it emits a growl-like sound, known in Polish as chruczenie ({{IPAc-pl|x|r|u|tʂ|ɛ|ɲ|ɛ}}). This sound can also be heard from wisent males during the mating season.{{cite web|title = The royal European bison|url = http://hunting.info.pl/2016/02/11/krolewskie-zubry/?lang=en|publisher = Łowiec Polski|date = 2016|access-date = 2 December 2019|archive-date = 31 January 2021|archive-url = https://web.archive.org/web/20210131125220/http://hunting.info.pl/2016/02/11/krolewskie-zubry/?lang=en|url-status = live}}

File:Cave of Altamira and Paleolithic Cave Art of Northern Spain-110113.jpg]]The similar skeletal morphology of the wisent with the steppe bison (Bison priscus) which also formerly inhabited Europe complicates the understanding of the early evolution of the European bison. It is thought that European bison genetically diverged from steppe bison (as well as modern American bison, which are descended from steppe bison) at least 100,000 years ago.{{Cite journal |last1=Grange |first1=Thierry |last2=Brugal |first2=Jean-Philip |last3=Flori |first3=Laurence |last4=Gautier |first4=Mathieu |last5=Uzunidis |first5=Antigone |last6=Geigl |first6=Eva-Maria |date=September 2018 |title=The Evolution and Population Diversity of Bison in Pleistocene and Holocene Eurasia: Sex Matters |journal=Diversity |language=en |volume=10 |issue=3 |pages=65 |doi=10.3390/d10030065 |doi-access=free}} While nuclear DNA indicates that the two living bison species are each other's closest living relatives, the mitochondrial DNA of European bison is more closely related to that of aurochs and their domestic cattle descendants, which is suggested to be the result of either incomplete lineage sorting or ancient introgression.

Bb1 has been found across Europe spanning from France to the Caucasus, while Bb2 was originally only found in the Caucasus before expanding westwards from around 14,000 years ago.

While some studies have estimated that modern European bison derive 10% of their ancestry from aurochs via interspecies gene flow, other authors have considered this a gross overstimate and based on flawed data, and not supported by the data from the full nuclear genome of the wisent, and that the actual contribution from aurochs/cattle around 2.4-3.2%, which is suggested to have occurred in the last 70,000 years.

Historically, the lowland European bison's range encompassed most of the lowlands of northern Europe, extending from the Massif Central to the Volga River and the Caucasus. It may have once lived in the Asiatic part of what is now the Russian Federation, reaching to Lake Baikal and Altai Mountains in east.Taras Petrovich Sipko, 2009, [http://www.smz.waw.pl/wydawnictwa/biuletyn2/20_Sipko.pdf European bison in Russia – past, present and future] {{Webarchive|url=https://web.archive.org/web/20220902215257/https://www.smz.waw.pl/wydawnictwa/biuletyn2/20_Sipko.pdf |date=2 September 2022 }} (pdf) the European Bison Conservation Newsletter Vol 2 (2009), pp.148–159, the Institute of Problems Ecology and Evolution RAS, Retrieved on October 18, 2022 The European bison is known in southern Sweden only between 9500 and 8700 BP, and in Denmark similarly is documented only from the Pre-Boreal.The Holocene distribution of European bison – the archaeozoological record.

Within mainland Europe, its range decreased as human populations expanded and cut down forests. They seemed to be common in Aristotle's period on Mount Mesapion (possibly the modern Ograzhden). In the same wider area Pausanias calling them Paeonian bulls and bison, gives details on how they were captured alive; adding also the fact that a golden Paeonian bull head was offered to Delphi by the Paeonian king Dropion (3rd century BC) who lived in what is today Tikveš.Παυσανίας 2nd cent A.D.: Ελλάδος περιήγησης.

In 1513 the Białowieża Forest, at this point one of the last areas on Earth where the European bison still roamed free, was transferred from the Troki Voivodeship of Lithuania to the Podlaskie Voivodeship, which after the Union of Lublin became part of the Polish Crown. In the Polish–Lithuanian Commonwealth, at first European bison in the Białowieża Forest were legally the property of the Grand Dukes of Lithuania and later belonged to the Crown of the Kingdom of Poland. Polish-Lithuanian rulers took measures to protect the European bison, such as King Sigismund II Augustus who instituted the death penalty for poaching bison in Białowieża in the mid-16th century. Wild European bison herds existed in the forest until the mid-17th century. In 1701, King Augustus II the Strong greatly increased protection over the forest; the first written sources mentioning the use of some forest meadows for the production of winter fodder for the bison come from this period.{{cite book|editor-last=Samojlik|editor-first=Tomasz|date=2005|title=Ochrona i Łowy.

During World War I, occupying German troops killed 600 of the European bison in the Białowieża Forest for sport, meat, hides and horns.

The International Society for the Preservation of the Wisent was founded on 25 and 26 August 1923 in Berlin, following the example of the American Bison Society. The first chairman was Kurt Priemel, director of the Frankfurt Zoo, and among the members were experts like Hermann Pohle, Max Hilzheimer and Julius Riemer. The first goal of the society was to take stock of all living bison, in preparation for a breeding programme. Important members were the Polish Hunting Association and the Poznań zoological gardens, as well as a number of Polish private individuals, who provided funds to acquire the first bison cows and bulls. The breeding book was published in the company's annual report from 1932. While Priemel aimed to grow the population slowly with pure conservation of the breeding line, Lutz Heck planned to grow the population faster by cross-breeding with American bison in a separate breeding project in Munich, in 1934.

Heck gained the support of then Reichsjägermeister Hermann Göring, who hoped for huntable big game.Irina Steinmann: Nils Seethaler hat zur Person Julius Riemer geforscht. In: Wittenberger Sonntag vom 10. Mai 2019. Heck promised his powerful supporter in writing: "Since surplus bulls will soon be set, the hunting of the Wisent will be possible again in the foreseeable future". Göring himself took over the patronage of the German Professional Association of Wisent Breeders and Hegers, founded at Heck's suggestion. Kurt Priemel, who had since resigned as president of the International Society for the Preservation of the Wisent, warned in vain against "manification". Heck answered by announcing that Göring would take action against Priemel if he continued to oppose his crossing plans. Priemel was then banned from publishing in relation to bison breeding, and the regular bookkeeper of the International Society, Erna Mohr, was forced to hand over the official register in 1937. Thus, the older society was effectively incorporated into the newly created Professional Association. After the Second World War, therefore, only the pure-blooded bison in the game park Springe near Hanover were recognised as part of the international herd book.Urmacher unerwünscht. Berliner Zoo.

In 2005–2007, a wild bison nicknamed Pubal became renowned in southeast Poland due to his friendly interactions with humans and unwillingness to reintegrate into the wild.{{cite web|url=https://fakty.interia.pl/podkarpackie/news-ocalony-zubr-nie-chce-zyc-na-wolnosci,nId,1130036|title=Ocalony żubr nie chce żyć na wolności|publisher=Interia|date=2007-01-02|access-date=2019-11-29|archive-date=20 December 2023|archive-url=https://web.archive.org/web/20231220072904/https://wydarzenia.interia.pl/|url-status=live}} As of 2014 there were 1,434 wisents in Poland, out of which 1,212 were in free-range herds and 522 belonged to the wild population in the Białowieża Forest. Compared to 2013, the total population in 2014 increased by 4.1%, while the free-ranging population increased by 6.5%. Bison from Poland have also been transported beyond the country's borders to boost the local populations of other countries, among them Bulgaria, Spain, Romania, Czechia and others. Poland has been described as the world's breeding centre of the European bison, where the bison population doubled between 1995 and 2017, reaching 2,269 by the end of 2019 – the total population has been increasing by around 15% to 18% yearly.

The European bison is a herd animal, which lives in both mixed and solely male groups. Mixed groups consist of adult females, calves, young aged 2–3 years, and young adult bulls. The average herd size is dependent on environmental factors, though on average, they number eight to 13 animals per herd. Herds consisting solely of bulls are smaller than mixed ones, containing two individuals on average. European bison herds are not family units. Different herds frequently interact, combine, and quickly split after exchanging individuals.

Bison social structure has been described by specialists as a matriarchy, as it is the cows of the herd that lead it, and decide where the entire group moves to graze.{{cite web|title = Leśnicy wołają żubry na siano|url = https://tvnmeteo.tvn24.pl/informacje-pogoda/polska,28/lesnicy-wolaja-zubry-na-siano,18741,1,0.html|publisher = TVN Meteo|author = Mirosław Androsiuk|date = 26 January 2012|access-date = 2 December 2019|archive-date = 28 December 2021|archive-url = https://web.archive.org/web/20211228030217/https://tvn24.pl/tvnmeteo/najnowsze/lesnicy-wolaja-zubry-na-siano-4878020|url-status = live}} Although larger and heavier than the females, the oldest and most powerful male bulls are usually satellites that hang around the edges of the herd to protect the group.{{cite AV media|people=Marta Kądziela (Director)|date=24 September 2014|title=Ocalony Świat – odc. 2 – Leśny majestat|trans-title = Saved World – Episode 2 – Forest Majesty|medium=Documentary|location=Poland|publisher=TVP1}} Bulls begin to serve a more active role in the herd when a danger to the group's safety appears, as well as during the mating season – when they compete with each other.{{cite web|title = Żubr dostał kosza, więc uciekł z pszczyńskiego rezerwatu|url = https://dziennikzachodni.pl/zubr-dostal-kosza-wiec-uciekl-z-pszczynskiego-rezerwatu/ar/240797|publisher = Dziennik Zachodni|author = Sylwia Plucińska|date = 6 April 2010|access-date = 2 December 2019|archive-date = 31 January 2021|archive-url = https://web.archive.org/web/20210131163522/https://dziennikzachodni.pl/zubr-dostal-kosza-wiec-uciekl-z-pszczynskiego-rezerwatu/ar/240797|url-status = live}}

Territory held by bulls is correlated by age, with young bulls aged between five and six tending to form larger home ranges than older males. The European bison does not defend territory, and herd ranges tend to greatly overlap. Core areas of territory are usually sited near meadows and water sources.

The rutting season occurs from August through to October. Bulls aged 4–6 years, though sexually mature, are prevented from mating by older bulls. Cows usually have a gestation period of 264 days, and typically give birth to one calf at a time.

On average, male calves weigh {{convert|27.6|kg|lb|sigfig=3|abbr=on}} at birth, and females {{convert|24.4|kg|lb|sigfig=3|abbr=on}}. Body size in males increases proportionately to the age of 6 years. While females have a higher increase in body mass in their first year, their growth rate is comparatively slower than that of males by the age of 3–5. Bulls reach sexual maturity at the age of two, while cows do so in their third year.

Adult European bison are (on average) taller than American bison, and have longer legs.Trophy Bowhunting: Plan the Hunt of a Lifetime and Bag One for the Record Books, by Rick Sapp, Edition: illustrated, published by Stackpole Books, 2006, {{ISBN|0-8117-3315-7}}, 978-0-8117-3315-1 European bison tend to browse more, and graze less than their American relatives; to accommodate this their necks are set differently. Compared to the American bison, the nose of the European bison is set further forward than the forehead when the neck is in a neutral position.

The body of the wisent is less hairy, though its tail is hairier than that of the American species. The horns of the European bison point forward through the plane of their faces, making them more adept at fighting through the interlocking of horns in the same manner as domestic cattle, unlike the American bison, which favours charging.American Bison: A Natural History, By Dale F. Lott, Harry W. Greene, ebrary, Inc., Contributor Harry W.

In terms of behavioural capability, European bison runs slower and with less stamina yet jumps higher and longer than American bisons, showing signs of more developed adaptations into mountainous habitats.

Genetic variability continues to shrink. From five initial bulls, all current European bison bulls have one of only two remaining Y chromosomes.

The largest European bison herds — of both captive and wild populations — are still located in Poland and Belarus, the majority of which can be found in the Białowieża Forest including the most numerous population of free-living European bison in the world with most of the animals living on the Polish side of the border. Poland remains the world's breeding centre for the wisent. In the years 1945 to 2014, from the Białowieża National Park alone, 553 specimens were sent to most captive populations of the bison in Europe as well as all breeding sanctuaries for the species in Poland.

Since 1983, a small reintroduced population lives in the Altai Mountains. This population suffers from inbreeding depression and needs the introduction of unrelated animals for "blood refreshment". In the long term, authorities hope to establish a population of about 1,000 animals in the area. One of the northernmost current populations of the European bison lives in Vologodskaya Oblast in the Northern Dvina valley at about 60°N. It survives without supplementary winter feeding. Another Russian population lives in the forests around the Desna River on the border between Russia and Ukraine. The north-easternmost population lives in Pleistocene Park south of Chersky in Siberia, a project to recreate the steppe ecosystem which began to be altered 10,000 years ago. Five wisents were introduced on 24 April 2011. The wisents were brought to the park from the Prioksko-Terrasny Nature Reserve near Moscow. The bison originated from a population in Denmark. Winter temperatures often drop below −50 °C. Four of the five bison have subsequently died due to problems acclimatizing to the low winter temperature.

Plans are being made to reintroduce two herds in Germany{{cite web|url=http://www.wisent-welt.de/|title=Startseite – Wisent Welt|access-date=20 November 2011|archive-date=3 December 2011|archive-url=https://web.archive.org/web/20111203200821/http://www.wisent-welt.de/|url-status=live}} and in the Netherlands in Oostvaardersplassen Nature Reserve{{cite web|url=http://www.lhnet.org/second-group-of-3-european-bison-from-poland-bialowieza-was-released-today/|title=Second group of 3 European bison from Poland (Białowieża) was released today|publisher=Large Herbivore Network|access-date=14 June 2012|archive-url=https://web.archive.org/web/20130522153157/http://www.lhnet.org/second-group-of-3-european-bison-from-poland-bialowieza-was-released-today/|archive-date=22 May 2013|url-status=dead}} in Flevoland as well as the Veluwe.

In March 2016, a herd was released in the Maashorst Nature Reserve in North Brabant. Zoos in 30 countries also have quite a few bison involved in captive-breeding programs.

Representations of the European bison from different ages, across millennia of human society's existence, can be found throughout Eurasia in the form of drawings and rock carvings; one of the oldest and most famous instances of the latter can be found in the Cave of Altamira, present-day Spain, where cave art featuring the wisent from the Upper Paleolithic was discovered.{{Cite journal|author=Sztych, D.|title=Żubr w kulturze|journal=Życie Weterynaryjne|volume=89|issue=10|pages=857–865|date=2014}} The bison has also been represented in a wide range of art in human history, such as sculptures, paintings, photographs, glass art, and more.{{Cite journal|author=Sztych, D.|title=Kulturotwórcza rola żubra|journal=European Bison Conservation Newsletter|volume=1|issue=2008|pages=161–190|date=2008}} Sculptures of the wisent constructed in the 19th and 20th centuries continue to stand in a number of European cities; arguably the most notable of these are the zubr statue in Spała from 1862 designed by Mihály Zichy and the two bison sculptures in Kiel sculpted by August Gaul in 1910–1913. However, a number of other monuments to the animal also exist, such as those in Hajnówka and Pszczyna or at the Kyiv Zoo entrance. Mikołaj Hussowczyk, a poet writing in Latin about the Grand Duchy of Lithuania during the early 16th century, described the bison in a historically significant fictional work from 1523.{{cite book|last=Дарашкевіч|first=Віктар|year=1980|title=Паэма жыцця // Песня пра зубра|location=Minsk|pages=171–184}}

The European bison is considered one of the national animals of Poland and Belarus. Due to this and the fact that half of the worldwide European bison population can be found spread across these two countries, the wisent is still featured prominently in the heraldry of these neighbouring states (especially in the overlapping region of Eastern Poland and Western Belarus). Examples in Poland include the coats of arms of: the counties of Hajnówka and Zambrów, the towns Sokółka and Żywiec, the villages Białowieża and Narewka, as well as the coats of arms of the Pomian and Wieniawa families. Examples in Belarus include the Grodno and Brest voblasts, the town of Svislach, and others. The European bison can also be found on the coats of arms of places in neighbouring countries: Perloja in southern Lithuania, Lypovets and Zubrytsia in west-central Ukraine, and Zubří in east Czechia – as well as further outside the region, such as Kortezubi in the Basque Country, and Jabel in Germany.

A flavoured vodka called Żubrówka ({{IPAc-pl|ʐuˈbrufka}}), originating as a recipe of the szlachta of the Kingdom of Poland in the 14th century, has since 1928 been industrially produced as a brand in Poland.{{cite web|title = Żubrówka – kultowa wódka z trawką.

The bison also appears commercially as a symbol of a number of other Polish brands, such as the popular beer brand Żubr and on the logo of Poland's second largest bank, Bank Pekao S.A.
