We know that microbes contribute to the production of odors that some animals use to communicate, but how common is this phenomenon? Recent studies capitalizing on new molecular technologies are uncovering fascinating associations between microbes and odors of wild animals, but causality is difficult to ascertain. Fundamental questions about the nature of these unique host‐microbe interactions also remain unanswered. For instance, do microbes benefit from signaling associations with hosts? How does microbial community structure influence signal production? How do hosts regulate (...) microbes in order to generate appropriate signals? Here, we review the current state of knowledge on microbially produced signals in animals and discuss key research foci that can advance our understanding of microbial‐based signaling in the animal world.

Interpretations of family carer empowerment in much nursing research, and in home‐care practice and policy, rarely attend explicitly to families’ choice or control about the nature, extent or length of their involvement, or control over the impact on their own health. In this article, structural empowerment is used as an analytic lens to examine home‐care nurses’ interactions with families in one Western Canadian region. Data were collected from 75 hrs of fieldwork in 59 interactions (18 nurses visiting 16 families) and (...) interviews with 12 nurses and 11 family carers. Generally, nurses prioritized client empowerment, and their practice with families appeared oriented to supporting their role and needs as carers (i.e. rather than as unique individuals beyond the caring role), and reinforcing the caring role through validation and recognition. Although families generally expressed appreciation for these interactions, a structural empowerment lens illustrates how the broad context of home care shapes the interpretation and practice of empowerment in ways that can, paradoxically, be disempowering for families. Opportunities to effectively support family choice and control when a client is being cared for at home are discussed. (shrink)
