Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

Journal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.

The British Journal of Sociology, EarlyView.
ABSTRACT Advantaged young people may engage in transgressive or non‐conformist subcultural practices usually associated with disadvantaged youth. When undertaken from privileged positions, however, these practices can carry markedly different meanings, costs and rewards.

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone

Insect Science, EarlyView.
We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.
