Babirusa actually pierce the flesh in the snout. All species of babirusa are listed as threatened by the International Union for Conservation of Nature (IUCN), shown on their Red List since at least 2010 and current in 2017. The genus is monotypic within the subfamily Babyrousinae, or alternatively considered to form a tribe, Babyrousini, of the subfamily Suinae. To date, only one fossil skull has been found to suggest a larger ancestor. All members of the genus were considered part of a single species until recently, the babirusa or pig-deer, "B. babyrussa", but following the split into several species, this scientific
Conductor of an abelian variety measure of wild ramification. When "F" is a number field, the conductor ideal of "A" is given by Conductor of an abelian variety In mathematics, in Diophantine geometry, the conductor of an abelian variety defined over a local or global field "F" is a measure of how "bad" the bad reduction at some prime is. It is connected to the ramification in the field generated by the torsion points. For an abelian variety "A" defined over a field "F" as above, with ring of integers "R", consider the Néron model of "A", which is a 'best possible' model of "A"
