Keywords:

  • tropical bird extinctions - current bird extinction rate, 30 times more than expected;
  • concept of extinction debt - whether birds are the most endangered taxa;
  • background extinction rate, one extinction per million species-years (MSY) - consequence of environmental change, newly established competitive interactions, and occasional catastrophes;
  • Stork (2010), arguing that species extinctions - less frequent than expected, due to factors as increased availability of regenerating forests;
  • time taken to lose all the sensitive species - following habitat perturbation, called “relaxation time”;
  • recent bird extinctions - loss of bird species at San Antonio (Colombia), 1911 to 1990;
  • forest fragments, gaining disturbance-tolerance - or invasive species;
  • drivers of extinctions - synergistic feedbacks, threatening species in disturbed tropical rainforests, decreased survival, fecundity, resulting in extinction of a species;
  • specialization, one of the traits - making a species sensitive to disturbance;
  • extinction proneness - affected by size of a species' geographical range
