Frankenstein matrices: Among-population life history variation affects the reliability and predictions of demographic models.

Population matrix models are routinely used to study the demography of wild populations and to guide management choices. When vital rates are unknown for a specific population or life history stage, researchers often replace them with estimates from other populations of the same species. Such 'hybrid' matrices might ignore among-population life history variation and lead to incorrect inferences.

Prednisolone pharmacokinetics in dogs with protein-losing enteropathy.

Background: It is unknown if glucocorticoid malabsorption contributes to the approximate 50% treatment failure rate in dogs with protein-losing enteropathy (PLE).

Objective: To compare pharmacokinetics (PK) of orally administered prednisolone in dogs with PLE vs healthy controls.

Animals: Fourteen dogs with well-characterized PLE and 7 control dogs.

On the immature stages of some Merodontini hoverflies (Diptera: Syrphidae) from Europe and Africa.

The genera Eumerus and Merodon (Syrphidae: Merodontini) form together the most speciose grouping of hoverflies in the Palaearctic Region. However, little is known about the morphology and biology of their larvae. The few larvae of Eumerus and Merodon that have been uncovered are phytophagous in underground organs of plants (some Eumerus and all Merodon) or saprophagous in a variety of plants' parts (the reminder of Eumerus).

"If you weren't connected to the Internet, you were not alive": experience of using social technology during COVID-19 in adults 50.

Introduction: Loneliness and social isolation reduce physical and mental wellbeing. Older adults are particularly prone to social isolation due to decreased connection with previous social networks such as at workplaces. Social technology can decrease loneliness and improve wellbeing.
