Genome Streamlining: Effect of Mutation Rate and Population Size on Genome Size Reduction.

Genome streamlining, i.e. genome size reduction, is observed in bacteria with very different life traits, including endosymbiotic bacteria and several marine bacteria, raising the question of its evolutionary origin.

Detecting the ecological footprint of selection.

The structure of communities is influenced by many ecological and evolutionary processes, but the way these manifest in classic biodiversity patterns often remains unclear. Here we aim to distinguish the ecological footprint of selection-through competition or environmental filtering-from that of neutral processes that are invariant to species identity. We build on existing Massive Eco-evolutionary Synthesis Simulations (MESS), which uses information from three biodiversity axes-species abundances, genetic diversity, and trait variation-to distinguish between mechanistic processes.

Forward-in-time simulation of chromosomal rearrangements: The invisible backbone that sustains long-term adaptation.

While chromosomal rearrangements are ubiquitous in all domains of life, very little is known about their evolutionary significance, mostly because, apart from a few specifically studied and well-documented mechanisms (interaction with recombination, gene duplication, etc.), very few models take them into account. As a consequence, we lack a general theory to account for their direct and indirect contributions to evolution.

Assessing inter-rater agreement of the intellectual disability-frailty index short form: A descriptive pilot study.

Frailty is a health concern for many adults with intellectual disability and should be measured to detect at-risk conditions, monitor disease, plan treatment, and gauge mortality. This descriptive pilot study evaluated measurement consistency (inter-rater agreement) of the Intellectual Disability-Frailty Index Short Form among multiple assessors with 20 adults ( age = 48.3 years) who had intellectual and multiple disabilities.

Teaching clinicians and nurses to prepare for and present at interdisciplinary meetings through behavioral skills training.

Behavior analysts frequently collaborate with interdisciplinary colleagues to share information and make decisions about client services. This study evaluated the effects of behavioral skills training on preparation for and presentation during interdisciplinary review team meetings by clinicians (n = 4) and nurses (n = 4) at a residential school for students with intellectual and neurodevelopmental disabilities. The primary dependent measure was the percentage of preparation and presentation steps from task-analyzed behavior checklists that the participants implemented correctly.
