Monogamy: Cause, Consequence or Corollary of Success in Wild Canids?

摘要: The Canidae are successful, being a widespread, abundant, speciose, and adaptable family. Several canids in particular have recently experienced rapid expansions range abundance, with similar situations mirrored on several continents by different species. Despite extreme behavioural diversity between within species, monogamy is common denominator canid societies. In this review, we ask why monogamous how related to their success. We begin an overview of social monogamy, describing the pair bonding, paternal care, often alloparental care that characteristic family, discuss theories evolution mammalian monogamy. maintained canids, either voluntarily or enforced, ecological conditions influence functional advantages ability for enforcement thus whether maintained. Social does not necessitate exclusive mating many exhibit extra-pair paternity. consider costs benefits male female can shift cost/benefit balance affect its prevalence.
