The Arctic is warming faster than anywhere else of comparable size on Earth, impacting global climate feedbacks and the Arctic biota. However, a warm Arctic is not novel. The Late Cretaceous fossil record of the region enables a detailed reconstruction of polar environmental conditions, and a thriving extinct ecosystem, during a previous 'hothouse’ global climate. Using leaf form (physiognomy) and tree ring characteristics we reconstruct Cenomanian to Coniacian polar thermal and hydrological regimes over an average annual cycle at eight locations in NE Russia and northern Alaska. A new high spatial resolution (∼1 km) WorldClim2 calibration of the Climate Leaf Analysis Multivariate Program (CLAMP) yields results similar to, but often slightly warmer than, previous analyses, but also provides more detailed insights into the hydrological regime through the return of annual and seasonal vapour pressure deficit (VPD), potential evapotranspiration (PET) estimates and soil moisture, as well as new thermal overviews through measures of thermicity and growing degree days. The new results confirm the overall warmth of the region, particularly close to the Arctic Ocean, but reveal strong local differences that may be related to palaeoelevation in the Okhotsk–Chukotka Volcanogenic Belt in NE Russia. While rainfall estimates have large uncertainties due to year-round wet soils in most locations, new measures of VPD and PET show persistent high humidity, but with notably drier summers at all the Arctic sites.

Coho salmon (Oncorhynchus kisutch), Chinook salmon (Oncorhynchus tshawytscha) and steelhead (Oncorhynchus mykiss) in Puget Sound and the Strait of Georgia have exhibited declines in marine survival over the last 40 years. While the cause of these declines is unknown, multiple factors, acting cumulatively or synergistically, have likely contributed. To evaluate the potential contribution of a broad suite of drivers on salmon survival, we used qualitative network modelling (QNM). QNM is a conceptually based tool that uses networks with specified relationships between the variables. In a simulation framework, linkages are weighted and then the models are subjected to user-specified perturbations. Our network had 33 variables, including: environmental and oceanographic drivers (e.g., temperature and precipitation), primary production variables, food web components from zooplankton to predators and anthropogenic impacts (e.g., habitat loss and hatcheries). We included salmon traits (survival, abundance, residence time, fitness and size) as response variables. We invoked perturbations to each node and to suites of drivers and evaluated the responses of these variables. The model showed that anthropogenic impacts resulted in the strongest negative responses in salmon survival and abundance. Additionally, feedbacks through the food web were strong, beginning with primary production, suggesting that several food web variables may be important in mediating effects on salmon survival within the system. With this model, we were able to compare the relative influence of multiple drivers on salmon survival.

Governmental development strategies focus on entrepreneurship as a major resource for the economic development of indigenous peoples. While initiatives and programs are locally based, there is a debate in the academic literature about how contextual factors affect the identification of indigenous entrepreneurship. The purpose of this paper is to analyze and integrate indigenous entrepreneurship literature to identify the main indigenous entrepreneurship models. Thus, a systematic literature review was conducted. In total, 25 relevant articles were identified in selected electronic databases and manual searches of Australian Business Deans Council ranked journals from January 1, 1995 to the end of 2016. Using a systematic analysis of sociocultural contexts and locations, the paper proposed that a typology of contextualized indigenous entrepreneurship models was possible, that were classified as urban, remote and rural. The parameters of these models, and their potential theoretical and practical applications to the study and practice of indigenous entrepreneurship ecosystems were also outlined.

‘Innovation’ has become a buzzword in academic papers, news articles, and book titles, but it is variously defined and is often referred to as ‘invention’ or ‘design’. A consensus of understanding the interrelationships of the concepts and activities pertaining to innovation is needed to guide collective action for innovation. This paper proposes a united view of the innovation process, which advocates uniting the complementary (1) science, (2) design, and (3) entrepreneurship sub-processes of innovation. The shared creative, uncertain, and costly nature of these three processes also implies an opportunity to leverage design science to understand and guide the science and entrepreneurship processes. This paper describes the benefits, major challenges, and actionable strategies for uniting science, design, and entrepreneurship as sub-processes of innovation, with a few detailed real life examples. The variety of the cases and examples shows that science, design, and entrepreneurship sub-processes can be effectively united to different extents, within and across organizations and innovation ecosystems.

Biodiversity is an abstract concept, attracting various responses from different people according to where they have come from and what ecosystems they have been closely linked to. In theory, most people would agree that protecting biodiversity is an important process, but in practice, few people commit to actions on a local level. This paper explores a situation faced in the Northern Territory where environmental educators seek to engage hearts, hands and minds to protect biodiversity but it is difficult to gain commitment given a diverse and transient community such as exists in Darwin. The survey of 175 tertiary students at Charles Darwin University develops insights into how individuals perceive and name local mangrove and savanna ecosystems, and which areas they would want to conserve. Results have implications for local environmental education. Suggestions are made about how awareness of and actions for biodiversity in the Top End could be extended.

This article examines postcolonial representations of the jungle and the desert, focusing on two novels in particular: Étienne Goyémidé’s Le silence de la forêt (1984) and Tahar Djaout’s L’invention du désert (1987). Postcolonial literary representations of these “extreme” landscapes are layered with allusions and almost always engage in an intertextual conversation with the colonial genres that influenced readers’ conception of these spaces. The specificity of jungle and desert serves in contemporary postcolonial literature as a foil to homogenizing forces of both the past and the present, as seen in the stylistic techniques authors employ to depict these spaces. These stylistic techniques often work in two seemingly opposing directions: they “naturalize” landscapes that are often portrayed as inhuman and contrast them to the “unnatural” structures of colonial and postcolonial society, while at the same time embodying and claiming the distortion or disorientation inherent in those landscapes. These complex, multifaceted, geographically rooted descriptions, which incorporate and react to a variety of historical and cultural factors, take what I call an ecosystem approach, rather than continuing to rely on a false nature/culture division.

Several recent papers have criticized the scientific robustness of the fisheries management system used by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), including that for Ross Sea toothfish. Here we present a response from the wider CCAMLR community to address concerns and to correct some apparent misconceptions about how CCAMLR acts to promote conservation whilst allowing safe exploitation in all of its fisheries. A key aspect of CCAMLR’s approach is its adaptive feedback nature; regular monitoring and analysis allows for adjustments to be made, as necessary, to provide a robust management system despite the statistical uncertainties inherent in any single assessment. Within the Ross Sea, application of CCAMLR’s precautionary approach has allowed the toothfish fishery to develop in a steady fashion with an associated accumulation of data and greater scientific understanding. Regular stock assessments of the fishery have been carried out since 2005, and the 2013 stock assessment estimated current spawning stock biomass to be at 75% of the pre-exploitation level. There will always be additional uncertainties which need to be addressed, but where information is lacking the CCAMLR approach to management ensures exploitation rates are at a level commensurate with a precautionary approach.

There is significant concern about potential ecological effects of introduced organisms, including non-indigenous species and those created by genetic modification. This paper presents an Ecopath with Ecosim modelling approach, designed to examine long-term trophic effects of growth hormone (GH) transgenic coho salmon should they ever escape to a coastal salmonid ecosystem, namely the Strait of Georgia in British Columbia (Canada). The model showed that the effects of introduced GH transgenic coho salmon varied with their biomass, diet, structure of the invaded ecosystem, and environmental conditions. Occasional escapes of non-reproductive salmon did not have a significant impact on the example ecosystem. However, effects of GH coho salmon varied with their diet when large numbers of these fish were present in the simulated ecosystem (for example, when they constituted 20% of total current aquaculture production in the area). Further, climate-driven changes in the biomass of low trophic levels (bottom-up effects) could have a greater impact on the ecosystem than the introduction of large numbers of GH coho salmon. A new version of Ecopath with Ecosim's Monte Carlo approach showed that the model predictions were robust to GH coho salmon's Ecopath parameters, but more sensitive to vulnerabilities of prey to GH coho salmon. Modelling ecosystem effects of genetically modified organisms provides a complementary approach for risk assessments when data from nature are not readily obtainable.

With a rich mix of theatrical material to bring to the table, the climate-change debate playing out in the public domain would seem well adapted to the stage, and has often been presented in docu-dramatic form, as in Al Gore's well-known film An Inconvenient Truth. But until relatively recently climate change and the science relating to it have been conspicuous by their absence from the stage. Early movers on the climate-change theatre scene included Caryl Churchill's 2006 climate-change libretto for the London Proms, We Turned on the Light, and John Godber's 2007 play Crown Prince. Since then, interest has steadily increased. In 2009 came Steve Waters's double bill The Contingency Plan (On the Beach and Resilience). This was quickly followed by Earthquakes in London by Mike Bartlett in 2010, and by three further plays in the spring of 2011: Greenland, the collaborative work of Moira Buffini, Matt Charman, Penelope Skinner, and Jack Thorne; The Heretic by Richard Bean; and Wastwater by Simon Stephens. In this article Julie Hudson focuses on three of these works to explore how the plays engage with the debate through the medium of climate-change science. As her article suggests, these British climate-change plays make an important and occasionally subversive contribution to the long-running discourse on the relationship between science, the ecosystem, and human beings. In performance, they succeed in turning a subject that has been overplayed for effect in the public domain into compelling theatre. Julie Hudson is currently a visiting fellow at the Smith School of Enterprise and the Environment, Oxford University.

Using archival photography and satellite imagery, we have analysed the rates of advance or retreat of 103 coastal glaciers on South Georgia from the 1950s to the present. Ninety-seven percent of these glaciers have retreated over the period for which observations are available. The average rate of retreat has increased from 8 Ma-1 in the 1950s to 35 Ma-1 at present. The largest retreats have all taken place along the north-east coast, where retreat rates have increased to an average of 60 Ma-1 at present, but those on the south-west coast have also been steadily retreating since the 1950s. These data, along with environmental information about South Georgia, are included in a new Geographic Information System (GIS) of the island. By combining glacier change data with the present distribution of both endemic and invasive species we have identified areas where there is an increased risk of rat invasion to unoccupied coastal regions that are currently protected by glacial barriers. This risk has significant implications for the surrounding ecosystem, in particular depletion in numbers of important breeding populations of ground-nesting birds on the island.
