Paternal Care Decreases Foraging Activity and Body Condition, but Does Not Impose Survival Costs to Caring Males in a Neotropical Arachnid

Abstract: Exclusive paternal care is the rarest form of parental investment in nature and theory predicts that the maintenance of this behavior depends on the balance between costs and benefits to males. Our goal was to assess costs of paternal care in the harvestman Iporangaia pustulosa, for which the benefits of this behavior in terms of egg survival have already been demonstrated. We evaluated energetic costs and mortality risks associated to paternal egg-guarding in the field. We quantified foraging activity of male… Show more

“…Paternal care, however, does not seem to constrain mate acquisition: caring males can mate with as much as 15 females and take care of all of their eggs simultaneously in multiple clutches (Requena et al 2012). Mate search is exclusively accomplished by females, who may visit several males over the course of the breeding season.…”

“…Opiliões possuem uma grande sensibilidade à perda d´água e é comum se abrigarem em locais com baixa incidência de luz e de alta umidade (Santos, 2003;Santos, 2007;Requena et al, 2012;Buzatto et al, 2011). Alternativamente, repousam em folhas perto de rios (Buzatto et al, 2011;Requena et al, 2012).…”

“…Machos do opilião Neotropical Iporangaia pustulosa, por exemplo, exibem um marcado decréscimo da condição corporal ao longo do período de cuidado a prole, pois os machos guardiões abandonam a prole com uma frequência relativamente baixa e, quando o fazem, raramente conseguem obter alimento (Requena et al, 2012). Uma forma de compensar esses custos do cuidado sem abandonar a prole é o canibalismo filial, definido como o consumo da própria prole pelo indivíduo parental (FitzGerald, 1992).…”
