The exponential growth of studies on the biological response to ocean acidification over the last few decades has generated a large amount of data. To facilitate data comparison, a data compilation hosted at the data publisher PANGAEA was initiated in 2008 and is updated on a regular basis (doi:10.1594/PANGAEA.149999). By January 2015, a total of 581 data sets (over 4 000 000 data points) from 539 papers had been archived. Here we present the developments of this data compilation five years since its first description by Nisumaa et al. (2010). Most of study sites from which data archived are still in the Northern Hemisphere and the number of archived data from studies from the Southern Hemisphere and polar oceans are still relatively low. Data from 60 studies that investigated the response of a mix of organisms or natural communities were all added after 2010, indicating a welcomed shift from the study of individual organisms to communities and ecosystems. The initial imbalance of considerably more data archived on calcification and primary production than on other processes has improved. There is also a clear tendency towards more data archived from multifactorial studies after 2010. For easier and more effective access to ocean acidification data, the ocean acidification community is strongly encouraged to contribute to the data archiving effort, and help develop standard vocabularies describing the variables and define best practices for archiving ocean acidification data.

The Bakken region of North Dakota and Montana has experienced perhaps the greatest effects of increased oil and gas development in the United States, with major implications for local governments. Though development of the Bakken began in the early 2000s, large-scale drilling and population growth dramatically affected the region from roughly 2008 through today. This case study examines the local government fiscal benefits and challenges experienced by Dunn County and Watford City, which lie near the heart of the producing region. For both local governments, the initial growth phase presented major fiscal challenges due to rapidly expanding service demands and insufficient revenue. In the following years, these challenges eased as demand for services slowed due to declining industry activity and state tax policies redirected more funds to localities. Looking forward, both local governments describe their fiscal health as stronger because of the Bakken boom, though higher debt loads and an economy heavily dependent on the volatile oil and gas industry each pose challenges for future fiscal stability.

This article examines the 1938 historical novel 1649: A Novel of a Year by the Anglo-Australian communist polymath Jack Lindsay in the context of the politics of the Popular Front, and identifies the aesthetic and historiographic debates questions that inform Lindsay’s inventive rendition of the historical novel. The novel may be considered in light of what Lindsay later called his desire ‘to use the novel to revive revolutionary traditions’, as well as his ‘struggle to achieve an understanding of the Novel while writing novels’. Lindsay’s novel figures a reality becoming prosaic: it reproduces contemporary textual sources – tracts, pamphlets, newspapers – as part of its meditation on a nascent print culture whose products circulate in processes that mirror the increasingly conspicuous flow of commodities. In this sense, the novel offers a marxist reflection on its own conditions of possibility in emergent bourgeois culture, as well as intervening in the vexed question of the Civil War as a ‘bourgeois revolution’. The novel however seeks to capture a dialectical method of representing the revolution that acknowledges defeat while rearticulating the utopian content of the defeated radicals, a practice integral to Lindsay’s vision of popular history as a transhistorical dialogue. That utopian content is transmitted through two forms: popular song, which acts to supplement political writing; and the heroic portrayal of the Leveller John Lilburne on trial, whose conduct exemplifies praxis conceived as a unity of word, thought and action.
