Patterns of mouflon (Ovis gmelini) survival under moderate environmental conditions: effects of sex, age, and epizootics

摘要: We estimated survival probabilities over a 9-year period for an introduced population of Mediterranean mouflon (Ovis gmelini), applying capture – recapture models to resighting data from individually marked animals. Survival was high and constant among lambs, yearling males, adults both sexes, we were unable detect senescence old female yearlings varied widely years. No difference in between the sexes detected, indicating that costs sexual selection low this dimorphic species. suggest these results may be explained by lack limiting conditions on study site. An outbreak keratoconjunctivitis during rut 1993 caused fall annual sexes. Among decline all ages (approximately 23%), but females impact disease relation age, with young ewes particularly affected. Otherwise, appears stab...
