- Acoustic crypsis in southern right whale mother–calf pairs: infrequent, low-output calls to avoid predation?
Highlighted Article: Low-output infrequent calls in baleen whale mother–calf pairs may mediate contact between mother and calf, while decreasing the risk of detection by potential predators.
- Limits to sustained energy intake. XXIII. Does heat dissipation capacity limit the energy budget of lactating bank voles?
Summary: Fur removal increases both energy budget and reproductive output at peak lactation in a non-laboratory rodent, the bank vole, supporting the heat dissipation limit theory.
- Oxidative stress as an indicator of the costs of reproduction among free-ranging rhesus macaques
Summary: Measures of oxidative stress in rhesus macaques reveal more DNA oxidative damage in males than females, in mothers raising daughters rather than sons and show enduring costs of aggression for males.
