Improving the predictive power of food web analysis is a major challenge. Identifying the relationships that link topological and dynamical features may help. We used the predictions of loop analysis about the effect of perturbations targeted to the components of Barents sea food web to quantify their sensitivity and community impact, that we summarized in two new indices, NI and NS. Using a ...

Forestalling the decline of global biodiversity requires urgent and transformative action at all levels of government and society, particularly in the Arctic Ocean and adjacent seas where rapid changes are already underway. Amid growing scientific support and mounting pressure, the majority of nations have committed to the most ambitious conservation targets yet. However, without an approach ...

Vegetated coastal marine ecosystems are projected to expand northwards in the Arctic due to climate change, but the mechanisms for this expansion are complex and nuanced. Macroalgal biomass in the littoral areas of Svalbard has been increasing, but data at the glacier fronts are very scarce. In this study, we use hydroacoustics and video validation from an unmanned surface vehicle to survey macroalgal ...

In this article, we identify and discuss unifying principles to co-design transformational sustainable-tourism interventions through participatory methodologies. We conduct a meta-ethnographic synthesis of the emerging relevant tourism literature (14 articles), and we propose five methodological requirements that underpin effective interventions for sustainable tourism transformations. The requirements ...

Feedback is defined as a process in which students can benefit from information about their own performance to improve the quality of their work and learning strategies. This case study examines how students in a bachelor-level physiology course experienced their learning when receiving formative feedback through digital multiple-choice questions (MCQs) in the web-based learning platform Canvas. The ...

<p>Hypoxia may be defined as a state of O₂ deficiency in which cellular energetic homeostasis is challenged. Prolonged exposure to hypoxia can lead to a bioenergetic collapse as it induces a switch from mitochondrial oxidative metabolism to a mainly glycolytic one, which is not sustainable over time. Recent evidence shows that mitochondrial metabolic response to hypoxia also depends on ...

Public sector entrepreneurship (PSE) has emerged as a vital field, exploring how public servants leverage opportunities to create public value amidst unprecedented and unpredictable challenges in governance. This article navigates the expansive landscape of PSE literature, consolidating diverse theoretical perspectives and fragmented knowledge into a cohesive framework. Through an integrative and ...

Marine microalgae are a promising innovation platform for carbon capture and utilization (CCU) biotechnologies to mitigate industrial greenhouse gas emissions. However, industrial-scale cultivation of algal mono-cultures is challenging and often unscalable. Non-axenic microalgae in large semi-open photobioreactors lead to the co-cultivation of diverse microbial communities. There is limited knowledge ...

The novel concept of the review is a focus on the organisms living in the sea ice and what mechanisms they have developed for their existence. The review describes the physical environment of the sea ice and the microorganisms living there as microalgae, bacteria, virus, fungi, meio- and macrofauna where they inhabit the brine channels and exposed to low temperatures as down to −25 °C and high ...

Considering recent calls for change towards a more liveable tourism academia, we combined critical participatory action research with duoethnography to develop The Academic Line—a humorous comic project about academic life. We used traditional theories of humour to leverage the effectiveness of comics as communicative devices and explored how and to what extent our project promoted solidarity, ...
