Context: There are urgent calls to transition society to more sustainable trajectories, at scales ranging from local to global. Landscape sustainability (LS), or the capacity for landscapes to provide equitable access to ecosystem services essential for human wellbeing for both current and future generations, provides an operational approach to monitor these transitions. However, the complexity of landscapes complicates how and what to consider when assessing LS.
View Article and Find Full Text PDFJuniperus spp. are keystone shrubs in western North America and important climatic indicators in paleo-records. However, a lack of taxonomic resolution among fossil species limits our ability to track past environmental changes.

We assessed the SARS-CoV-2 antibody response of GENCOV participants cross-sectionally 1-, 6-, and 12-months following COVID-19 diagnosis to identify patient factors associated with more robust and durable humoral immune responses.
Materials And Methods: COVID-19 patients and a control cohort of vaccinated infection-naïve participants were recruited at hospital sites across the Greater Toronto Area in Ontario, Canada.
Article Synopsis
- Myosteatosis, characterized by fat buildup in skeletal muscle, is common among patients referred for liver transplantation (LT) and its effects on physical function and clinical outcomes remain uncertain.
- In a study involving 237 patients, those with myosteatosis showed increased frailty and poorer physical function compared to those without, but the impact on hospitalization rates and surgical complications was less clear after adjustments.
- Overall, while myosteatosis is linked to diminished physical abilities, it does not seem to significantly affect the likelihood of receiving a transplant or post-operative complications.
Background: Digital food records offer efficiencies in collecting and assessing dietary information remotely; however, research into factors impacting their translation into clinical settings is limited.
Methods: The study examined factors that may impact the integration of digital food records into clinical dietetic practice by assessing (1) the source and rate of data errors received, (2) the impact of dietitian-adjusted data on dietary variables and (3) the acceptance of use in a complex chronic condition cohort. Adults from specialist clinics enroled in a randomised controlled feasibility trial participated.
