TL;DR: The natural infection of Drosophila with a parasitoid wasp is employed to study energy regulation during immune response to show that a significant portion of nutrients are allocated to differentiating lamellocytes when they would otherwise be used for development.

TL;DR: It is concluded that less effective digging in F. mechowii can be compensated by the joint workforce of other family members, Alternatively, H. argenteocinereus, being a more effective digger, can afford a solitary way of life.

TL;DR: Monitoring of outside-nest activity in eusocial mole-rat species concluded that social cues in communally nesting mole-rats may disrupt (mask) temperature-related daily activity rhythms but probably only if the additional cost of thermoregulation is not too high, as it likely is in the Ansell’s mole- rat.

TL;DR: This is the first study reporting a positive correlation between msRMR and lifespan based on reproductive status, which contradicts common aging theories, but supports recently introduced models which do not necessarily link reproductive trade-offs to lifespan reduction.

TL;DR: It is demonstrated, for the first time, that sub-adult spruce bark beetles can mature over winter and the percentage survival was signifi cant, indicating that some of the beetles that did not complete their development before the onset of winter cancomplete their development during winter and potentially adversely affect forests and pose problems for their management.
