Night diving by some emperor penguins during the winter breeding period at Cape Washington

Evidence is obtained that some birds may feed before the egg is laid, and if they do, and some are males, then their fast is much less than 115 days, which is a better chance of completing the 65 day incubation fast and success in fledging the chick.

Energy saving processes in huddling emperor penguins: from experiments to theory

These processes, linked together, explain how huddling emperors save energy and maintain a constant body temperature, which ensures a successful incubation in the midst of the austral winter.

One for all and all for one: the energetic benefits of huddling in endotherms

This is the first attempt to review the various implications of this widely used behavioural strategy, huddling, in animals faced with high heat loss due to a high surface‐to‐volume ratio, poor insulation, or living in cold environments.

Ingested water equilibrates isotopically with the body water pool of a shorebird with unrivaled water fluxes.

It is concluded that the ingested water equilibrated rapidly with the body water pool even in an avian species that shows record water flux rates when living on ingested marine bivalves.

How do weather conditions affect the huddling behaviour of emperor penguins?

The first investigation into the effects of changes in wind speed and ambient temperature on different components of penguin huddling behaviour is reported, finding that emperor penguins complex huddled behaviour was modulated differently depending on these two parameters.

Body temperature changes induced by huddling in breeding male emperor penguins.

The first data on body temperature changes throughout the breeding cycle of emperor penguins is presented, suggesting that the energy savings of huddling birds is due to a metabolic depression, the extent of which depends on a reduction of body surface areas exposed to cold.

Safe Carrying of Heavy Infants Together With Hair Properties Explain Human Evolution

The focus is on safe infant carrying in primates, sexual selection among Hominoidea, fur reduction in hominins, and tensile properties of hominoid hairs, justifying the necessary change to bipedal locomotion from the overwhelming selective pressure of infant survival.

Thermoregulatory morphodynamics of honeybee swarm clusters.

The results quantify the hysteretic and anisotropic morphological responses of swarm clusters to ambient temperature variations while suggesting that both mechanical constraints and heat transfer govern their thermoregulatory morphodynamics.

Collective self-optimization of communicating active particles

The proposed optimal field–based collective interactions represent a generic concept at the interface of active matter physics, collective behavior, and microbiological chemotaxis which might serve as a useful ingredient to optimize ensembles of synthetic active agents or to help unveil aspects of the communication rules which certain social groups use to maximize their survival chances.

Energy expenditure for thermoregulation and locomotion in emperor penguins.

The data suggest that walking 200 km (from the sea to the rookery and back) requires less than 15% of the energy reserves of a breeding male emperor penguin initially weighing 35 kg.

Thermoregulation in fasting emperor penguins under natural conditions.

Emperor penguins breed during the cold antarctic winter; the males incubate the single egg while fasting for up to 4 mo and losing some 20 kg of their body mass, higher than predicted from general metabolic equations for birds.
