- This article proposes a new theoretical framework to study the dialectic of capital and nature over the longue durée of world capitalism. The author proposes that today’s global ecological crisis has its roots in the transition to capitalism during the long sixteenth century. The emergence of capitalism marked not only a decisive shift in the arenas of politics, economy, and society, but a fundamental reorganization of world ecology, characterized by a “metabolic rift,” a progressively deepening rupture in the nutrient cycling between the country and the city. Building upon the historical political economy of Marx, Foster, Arrighi, and Wallerstein, the author proposes a new research agenda organized around the concept of systemic cycles of agro-ecological transformation. This agenda aims at discerning the ways in which capitalism’s relationship to nature developed discontinuously over time as recurrent ecological crises have formed a decisive moment of world capitalist crisis, forcing successive waves of restructuring over long historical time.

Tidskriftsartikel (refereegranskat)abstract
- Faecal samples from 102 clinically healthy dairy cows, representing 34 farms in the Swedish province of Uppsala, were analysed for the presence of Listeria spp. using an enrichment procedure. Listeria monocytogenes was isolated from six (6%) and L. innocua from 2 (2%) cows. From each of the 6 samples positive for L. monocytogenes, 5 isolates were further characterised by restriction enzyme analysis using the 3 enzymes Apa I, Sma I, and Asc I, followed by pulsed-field gel electrophoresis. Three of the L. monocytogenes positive cows lived at the same farm, and they all harboured the same clonal type. One of these 3 cows also harboured a further clonal type of L. monocytogenes. The fact that one of the cows harboured 2 different clonal types of L. monocytogenes is important from an epidemiological point of view when routes of infection are to be investigated.
