Human activities shape global patterns of decomposition rates in rivers.

Rivers and streams contribute to global carbon cycling by decomposing immense quantities of terrestrial plant matter. However, decomposition rates are highly variable and large-scale patterns and drivers of this process remain poorly understood. Using a cellulose-based assay to reflect the primary constituent of plant detritus, we generated a predictive model (81% variance explained) for cellulose decomposition rates across 514 globally distributed streams.

How future orientations predict healthy outcomes: Information avoidance as a potential mechanism.

This study elucidates whether information avoidance may help explain demonstrated links between future orientation and health. In an online study, college students reported their self-reported prevention and detection health behaviors and responded to a prevention and detection health message. Path analyses indicated that information avoidance mediated the relationship with the future orientations (optimism and consideration of future consequences), such that, greater and more positive future orientations were associated with less information avoidance, and less information avoidance was associated with greater self-reported health behaviors and positive responses to health information.

Long-term ecological research in freshwaters enabled by regional biodiversity collections, stable isotope analysis, and environmental informatics.

Biodiversity collections are experiencing a renaissance fueled by the intersection of informatics, emerging technologies, and the extended use and interpretation of specimens and archived databases. In this article, we explore the potential for transformative research in ecology integrating biodiversity collections, stable isotope analysis (SIA), and environmental informatics. Like genomic DNA, SIA provides a common currency interpreted in the context of biogeochemical principles.

Assessing relationships between onsite wastewater treatment system maintenance patterns and system-level variables.

Globally, millions of households rely on onsite wastewater treatment systems (OWTSs), such as septic systems, to safely treat and dispose of wastewater. Conventional subsurface OWTSs are a common and affordable option for many landowners, and effectively remove pathogenic and nutrient pollution from wastewater when properly sited and maintained. However, OWTSs can also be a source of nonpoint pollution in watersheds when they are not functioning properly.

Can children learn verbs from events separated in time? Examining how variability and memory contribute to verb learning.

Children in everyday environments experience verbs separated by minutes or hours and linked to events that vary in their similarity. Prior studies have shown that seeing similar events can be beneficial for verb learning (e.g.
