Practice Patterns and Responses to the Patient-Driven Groupings Model and Coronavirus Disease 2019 Pandemic in Home Health Occupational Therapy: A Pilot Survey Study.

The purpose of the pilot survey was to understand current practice patterns and responses to the Patient-Driven Groupings Model and the coronavirus disease 2019 (COVID-19) pandemic in home health occupational therapy care. Fifty home health occupational therapy practitioners from 27 states in the United States completed the survey. Descriptive analysis was used to organize and summarize survey responses.

Population responses to a historic drought across the range of the common monkeyflower (Mimulus guttatus).

Premise: Due to climate change, more frequent and intense periodic droughts are predicted to increasingly pose major challenges to the persistence of plant populations. When a severe drought occurs over a broad geographical region, independent responses by individual populations provide replicated natural experiments for examining the evolution of drought resistance and the potential for evolutionary rescue.

Methods: We used a resurrection approach to examine trait evolution in populations of the common monkeyflower, Mimulus guttatus, exposed to a record drought in California from 2011 to 2017.

The Genetic Architecture of Plant Defense Trade-offs in a Common Monkeyflower.

Determining how adaptive combinations of traits arose requires understanding the prevalence and scope of genetic constraints. Frequently observed phenotypic correlations between plant growth, defenses, and/or reproductive timing have led researchers to suggest that pleiotropy or strong genetic linkage between variants affecting independent traits is pervasive. Alternatively, these correlations could arise via independent mutations in different genes for each trait and extensive correlational selection.
