Há 1 dia · This is a list of European species extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE) [A] and continues to the present day. [1] This list includes the European continent and its surrounding islands. All large islands in the Mediterranean Sea are ...
Há 1 dia · Oryzomys nelsoni. María Madre Island, Mexico. Last recorded in 1897. Possibly extinct due to introduced black rats. [13] Giant island deer mouse. Peromyscus nesodytes. Channel Islands of California. Most recent remains at Cave of the Chimneys, San Miguel Island, dated to around 950 CE.
Há 1 dia · The thylacine ( Thylacinus cynocephalus) is a large, carnivorous marsupial last seen in 1936. This is a list of Australia-New Guinea species extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE) [a] and continues to the present day.
Há 8 horas · Our first result (Theorem 21) provides sharp thresholds for rainbow cycles in edge-coloured graphs with 3 colours. Our second, and main, result (Theorem 35) is for the r = 3 case of Aharoni’s conjecture. We prove that if G is an n -vertex graph whose edges are coloured with n colours and each colour class has size at least 3, then G contains ...
Há 8 horas · More recently, the classes of stable polynomials and Lorentzian polynomials have appeared in representation theory, algebraic combinatorics, and even knot theory. We further highlight their ubiquity by introducing a large class of chromatic symmetric functions related to Hessenberg varieties and the Stanley–Stembridge conjecture that are ...
Há 8 horas · We consider a class of non-negative valued, time-changed spectrally positive Lévy processes stopped whenever hitting 0, which can be identified as continuous-state branching processes with population dependent branching rates.
Há 1 dia · A mastodon ( mastós 'breast' + odoús 'tooth') is a member of the genus Mammut (German for "mammoth"), which strictly defined, was endemic to North America and lived from the late Miocene to the early Holocene. Mastodons belong to the order Proboscidea, the same order as elephants and mammoths (which belong to the family Elephantidae ).
