Contributions to Behavioral Ecology

  • Falsifying the ‘multiple pairs in cathemeral lemurs’ hypothesis that explained even adult sex ratios in small lemur groups
  • Proposition of a new, testable hypothesis of defused sexual conflict and male cooperation
  • Proposing a causal link between life history traits commonly found in group-living lemurs, male coalition formation and the lack of convergence in group composition between lemurs and anthropoids
  • Demonstrating a systematic diet-related problem of feasibility with hormone analyses from feces
  • Proposing a theoretical model incorporating ecology based group size related variation in female physical condition into the Trivers-Willard hypothesis for adaptive sex ration variation
  • Demonstrating the effect of infanticide risk on male androgen and glucocorticoid levels
  • Proposing an explanation for the patchy occurrence of hibernation among cheirogaleids
  • Proposing how ecological, physiological, and social factors may explain the variation in social organization found among mouse lemurs
  • Providing the first proof of unconditional female dominance from a wild population of nocturnal lemurs
  • Identifying several cases of often ignored ecological influences on male social organization
  • Demonstrating that ecology can constrain group size even if social factors act limiting simultaneously
  • Showing that digestive constraints may explain large parts of the ‘folivore paradox’ of group size
  • Providing the first test of the socioecological model in a pair-living primate
  • Demonstrating the equal importance of variation in food-specific ingestion rates and nutritional composition for relative food quality
  • Proposing the intersexual feeding competition hypothesis for the evolution of pair-living
