Foraging Activity
Paternal care decreases foraging activity and body condition, but does not impose survival costs to caring males in a Neotropical arachnid.
... 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 ...
