This Danian hyperthermal event (the Dan-C2) has been documented from the fill of the Boltysh meteorite crater, Ukraine. Palynofloras recovered from the Boltysh crater fill show a trend from mesic forest to savannah ecosystem dominance on a millennial scale across the hyperthermal inception with no abrupt compositional shift. This longer-term trend is overprinted by moisture availability oscillations reflecting orbital forcing. Forcing is not directly tracked by the oscillations, which are composed of mesic forest and savannah palynofloras separated by rapid critical transitions. The absence of an ecological collapse at the Dan-C2 indicates that plant ecosystems experienced dominant forcing from orbital cyclicity, rather than a stochastic temperature rise.\n          <\/jats:p>","DOI":"10.1144\/jgs2014-130","type":"journal-article","created":{"date-parts":[[2015,5,22]],"date-time":"2015-05-22T01:05:00Z","timestamp":1432256700000},"page":"491-498","source":"Crossref","is-referenced-by-count":7,"title":["Long-term resilience decline in plant ecosystems across the Danian Dan-C2 hyperthermal event, Boltysh crater, Ukraine"],"prefix":"10.1144","volume":"172","author":[{"given":"D.
