Privatization and austerity measures have turned US prisons and jails into sites of financial extraction. As corrections systems have slashed budgets for essential services, incarcerated individuals are increasingly expected to cover the costs of their institutionalization, including amounts for administrative fees and legal support, and for covering basic necessities during incarceration. This article focuses on the commissary system as a central yet understudied institution of the American neo-liberal prison. It conceptualizes commissary as a double-edged institution: on the one hand, prison commissary stores—where people can purchase a wide variety of items, from extra food to small appliances—constitute a crucial mechanism for extending financial extraction inside carceral institutions, siphoning millions of dollars each year from impoverished households. At the same time, we argue, shopping at commissary allows incarcerated persons to mitigate against the punitive frugality imposed by the prison and to limit the reach of disciplinary power. Drawing on qualitative research with sixty formerly incarcerated men in New York State, and on the personal experiences of one of the authors with the New York penal system, this article reconstructs how access to economic capital functions as a mediating structure in contemporary US prisons, enabling some prisoners to negotiate carceral punishment, while leaving others fully exposed to its harmful consequences.

Only scarce information is available on how organic C is incorporated into the soil during the decay and how (micro) climate influences this process. Therefore, we investigated the effect of exposure and elevation on the organic litter decomposition and C-stabilisation in acidic soils of an Alpine environment. An experiment with artificially C labelled Norway spruce needles was carried out at north- and south-exposed sites between 1200 and 2400 m a.s.l. in the Italian Alps using mesocosms. After 1 year, the C recoveries of the bulk soil were 18.6% at the north-facing slopes and 31.5% at the south-facing slopes. A density fractionation into a light (LF; ≤1.6 g cm) and a heavy fraction (HF; >1.6 g cm) of the soil helped to identify how the applied substrate was stabilised. At the northern slope, 10.5% of the substrate was recovered in the LF and 8.1% in the HF and at the south-facing slope 22.8% in the LF and 8.1% in the HF. The overall C recovery was higher at the south-facing sites due to restricted water availability. Although the climate is humid in the whole area, soil moisture availability becomes more important at south-facing sites due to higher evapotranspiration. However, at sites >1700 m a.s.l, the situation changed, as the northern slope had higher recovery rates. At such altitudes, temperature effects are more dominant. This highlights the importance of locally strongly varying edaphic factors when investigating the carbon cycle. [ABSTRACT FROM AUTHOR]

Microbes drive leaf litter decomposition, and their communities are adapted to the local vegetation providing that litter. However, whether these local microbial communities confer a significant home-field advantage in litter decomposition remains unclear, with contrasting results being published. Here, we focus on a litter transplantation experiment from oak forests (home site) to two away sites without oak in South Tyrol (Italy). We aimed to produce an in-depth analysis of the fungal and bacterial decomposer communities using Illumina sequencing and qPCR, to understand whether local adaptation occurs and whether this was associated with litter mass loss dynamics. Temporal shifts in the decomposer community occurred, reflecting changes in litter chemistry over time. Fungal community composition was site dependent, while bacterial composition did not differ across sites. Total litter mass loss and rates of litter decomposition did not change across sites. Litter quality influenced the microbial community through the availability of different carbon sources. Additively, our results do not support the hypothesis that locally adapted microbial decomposers lead to a greater or faster mass loss. It is likely that high functional redundancy within decomposer communities regulated the decomposition, and thus greater future research attention should be given to trophic guilds rather than taxonomic composition.
