Peatland pools are tightly coupled to the contemporary carbon cycle.

Peatlands are globally important stores of soil carbon (C) formed over millennial timescales but are at risk of destabilization by human and climate disturbance. Pools are ubiquitous features of many peatlands and can contain very high concentrations of C mobilized in dissolved and particulate organic form and as the greenhouses gases carbon dioxide (CO ) and methane (CH ). The radiocarbon content ( C) of these aquatic C forms tells us whether pool C is generated by contemporary primary production or from destabilized C released from deep peat layers where it was previously stored for millennia.

Measuring the Influence of Curricular Content and Personal Stories on Substance Use Stigma.

Background: Understanding of the lived experience is an important educational strategy for improving attitudes toward stigmatized patient groups. This study evaluated the influence of a personal story intervention on nursing students' attitudes toward people who use opioids and measured attitudinal change from students' regular mental health and addictions curriculum.

Method: This study used a single-group longitudinal design.

Functional capacity and quality of life of hospitalized octogenarians.

Objective: To evaluate the ability to perform activities of daily living (ADL) and to correlate functional capacity with quality of life (QoL) of hospitalized octogenarians.

Method: A cross-sectional study with 128 patients using the quality of life instruments WHOQOL-OLD and WHOQOL-BREF and the Katz Scale.

Results: The majority of patients was fully dependent; patients with higher schooling had less independence; older adults with partial dependence and independence had higher scores in perceived QoL; in the domains of autonomy, past, present and future activities; and better overall QoL than those with full dependence.

Current forest carbon fixation fuels stream CO emissions.

Stream CO emissions contribute significantly to atmospheric climate forcing. While there are strong indications that groundwater inputs sustain these emissions, the specific biogeochemical pathways and timescales involved in this lateral CO export are still obscure. Here, via an extensive radiocarbon (C) characterisation of CO and DOC in stream water and its groundwater sources in an old-growth boreal forest, we demonstrate that the C-CO is consistently in tune with the current atmospheric C-CO level and shows little association with the C-DOC in the same waters.
