Public sector workers experience particular challenges from the state when they organize and take collective action. Accountable to administrators as well as parents, teachers are embedded within complex power relations at scales from the classroom to the district and the state or nation. This article draws on labor geography's understandings of how worker agency is socially situated, to explore how the capacities for protest of dissident elementary and secondary teachers in Mexico City have been limited. These obstacles are found within their workplaces governed by the local Secretary of Public Education, in broader political dynamics within the city and in a centralization of governance over education policy to the national level. As a result, between 2013 and 2016 , teachers here were less likely to join protests against policies initiated by President Enrique Peña Nieto that were widely deemed harmful to their professional autonomy, and which drew strong resistance in other regions of the country. This article concludes by briefly assessing how, as Peña Nieto's term concluded, dissident teachers turned towards the national election and an equivocal relationship with the center-left Morena party.

Since the early 1940s, the ecosystem approach has been developed in a variety of forms by North American ecologists. Lindeman established its foundation, with his focus on functional components and energy transfers between trophic levels; this view was developed further by several ecologists, including G. Evelyn Hutchinson, and H. T. and E. P. Odum. Ecosystem ecology eventually became closely associated with powerful American institutions, such as the Atomic Energy Commission, receiving ample support; in association with the International Biological Program it became known as "big ecology'. More recently, ecosystem ecology has exhibited strengthened interest in spatial patterns, the role of species in ecosystems, and global change. This history has encompassed various ontological, methodological, ethical and political claims regarding the place of this approach in the discipline of ecology and in environmental governance.
