Agnes Varda and JR's 2017 documentary 'Visages Villages' is an extended gesture toward a creative politics that privileges decentralized, communal, and constantly shifting authorial positions. The co-directors not only explore the French countryside in their creative endeavor, but also expand upon preconceived notions of what constitutes a creator and a creation. Using the writings of Gilles Deleuze and Felix Guattari as a theoretical framework, Varda and JR's interactions with space and place offer a radical and subversive transformation that necessarily multiples everything it touches. This multiplicity is enacted not only through a Deleuzean-Guattarian brand of corporeal movement, but through the consistent regeneration and recycling of individual texts and images, all of which coalesce into an endlessly transformative body of work that resists totalization even as it suggests that textual possibility.

This article explores the rich and generative spaces poised between Gilles Deleuze's movement-image and time-image semiotic regimes as laid out in Cinema I: The Movement-Image and Cinema II: The Time-Image. Using a transhistorical approach, this investigation provides insight into the myriad strands that cross between the proposed 'breaks' in cinema's evolution of style and structure. Using the works of Loïe Fuller and Agnes Varda, as well as the theoretical support of theorists such as Walter Benjamin, Henri Bergson, Jean Epstein and Gilles Deleuze himself, this research proposes a new mode of engaging with cinema's history and semiotic evolution that re-immerses cinema within the ceaseless flow of its duration. In doing so, Deleuze's historical break between the movement- and time-image regimes becomes an enriched and often contradictory space that offers a reimagining of cinema's possibilities.

Globally pervasive increases in atmospheric CO2 and nitrogen (N) deposition could have substantial effects on plant communities, either directly or mediated by their interactions with soil nutrient limitation. While the direct consequences of N enrichment on plant communities are well documented, potential interactions with rising CO2 and globally widespread phosphorus (P) limitation remain poorly understood. We investigated the consequences of simultaneous elevated CO2 (eCO2) and N and P additions on grassland biodiversity, community and functional composition in P‐limited grasslands. We exposed soil‐turf monoliths from limestone and acidic grasslands that have received >25 years of N additions (3.5 and 14 g m−2 year−1) and 11 (limestone) or 25 (acidic) years of P additions (3.5 g m−2 year−1) to eCO2 (600 ppm) for 3 years. Across both grasslands, eCO2, N and P additions significantly changed community composition. Limestone communities were more responsive to eCO2 and saw significant functional shifts resulting from eCO2–nutrient interactions. Here, legume cover tripled in response to combined eCO2 and P additions, and combined eCO2 and N treatments shifted functional dominance from grasses to sedges. We suggest that eCO2 may disproportionately benefit P acquisition by sedges by subsidising the carbon cost of locally intense root exudation at the expense of co‐occurring grasses. In contrast, the functional composition of the acidic grassland was insensitive to eCO2 and its interactions with nutrient additions. Greater diversity of P‐acquisition strategies in the limestone grassland, combined with a more functionally even and diverse community, may contribute to the stronger responses compared to the acidic grassland. Our work suggests we may see large changes in the composition and biodiversity of P‐limited grasslands in response to eCO2 and its interactions with nutrient loading, particularly where these contain a high diversity of P‐acquisition strategies or developmentally young soils with sufficient bioavailable mineral P.
