Randomized clinical trial protocol of an app-based intervention to prevent postpartum depression.

Purpose: To develop and evaluate the effectiveness of an asynchronously delivered app, InBloom, for postpartum depression (PPD) prevention relative to an evidence-based synchronously delivered in-person intervention, ROSE (Reach Out, Stay Strong, Essentials for mothers of newborns) for depression and return on investment via a prospective randomized controlled trial and quasi-experimental cohort analyses.

Background: PPD affects 1 in 7 gestational parents in the US, causing emotional distress, consequences for infant development and child adjustment, disruptions in family relationships, and financial burden. ROSE is an evidence-based intervention administered as four in-person group sessions plus one postpartum booster session.

Senescence as a trade-off between successful land colonisation and longevity: critical review and analysis of a hypothesis.

Background: Most common terrestrial animal clades exhibit senescence, suggesting strong adaptive value of this trait. However, there is little support for senescence correlated with specific adaptations. Nevertheless, insects, mammals, and birds, which are the most common terrestrial animal clades that show symptoms of senescence, evolved from clades that predominantly did not show symptoms of senescence.

Functional redundancy in local spatial scale microbial communities suggests stochastic processes at an urban wilderness preserve in Austin, TX, USA.

Empirical evidence supports selection of soil microbial communities by edaphic properties across large spatial scales; however, less is known at smaller spatial scales. The goal of this research was to evaluate relationships between ecosystem characteristics and bacterial community structure/function at broad taxonomic resolutions in soils across small spatial scales. We employed 16S rRNA gene sequencing, community-level physiological profiling and soil chemical analysis to address this goal.

Variable Influences of Water Availability and Rhizobacteria on the Growth of (Little Bluestem) at Different Ages.

There is significant interest in understanding the role of plant growth-promoting rhizobacteria (PGPR) in alleviating different types of plant stress. (little bluestem) is a moderately drought tolerant, perennial bunchgrass native to North America. The goal of this experiment was to evaluate whether the addition of a bacterial root isolate in the genus promoted the growth of with changes in water availability.
