Understanding the habitat use of individuals can facilitate methods to measure the degree to which populations will be affected by potential stressors. Such insights can be hard to garner for marine species that are inaccessible during phases of their annual cycles. Here, we quantify the link between foraging habitat and behaviour in an aquatic bird of high conservation concern, the red-throated diver () across three breeding populations (Finland, Iceland and Scotland) during their understudied moult period.

Objectives: To determine pressure beneath a cavesson noseband at five tightness levels during standing and chewing. It was hypothesised that increased noseband tightness is associated with increases in nasal and mandibular pressures while standing and chewing, accompanied by increases in eye temperature and blink rate.

Background: Effective and timely decongestion in acute heart failure (AHF) coupled with careful discharge planning is critical in the successful treatment of patients hospitalized for AHF. We leveraged an implementation science framework to develop a health system-wide diuretic management protocol (DMP) based on emerging clinical evidence.

Methods: We conducted stakeholder interviews using the Integrated Promoting Action on Research Implementation in Health Services (iPARiHS) Framework.
