The diel niche of brown bears: constraints on adaptive capacity in human‐modified landscapes
Ecography, Volume 2025, Issue 10, October 2025.Diel activity rhythms, representing the behavioral pattern of the sleep–wake cycle, may be adjusted by wildlife in response to changes in environmental conditions. An increase in nocturnality is typically recognized as an adaptive strategy to segregate from humans and mitigate heat stress. Numerous studies have investigated spatial patterns and habitat

Digital Technologies: Description, Classification, and Links to Circular Economy
Business Strategy and the Environment, Volume 34, Issue 6, Page 6612-6639, September 2025.ABSTRACT Digital technologies (DTs) and circular economy (CE) are currently two topics that are expected to contribute significantly to sustainable development, and digitization is generally considered a key enabler of CE. However, most studies only cover the most known Industry 4.0 technologies, and very limited research detailing how DTs can support ...

Model‐Driven Engineering for Digital Twins: Opportunities and Challenges
Systems Engineering, Volume 28, Issue 5, Page 659-670, September 2025.ABSTRACT Digital twins are increasingly used across a wide range of industries. Modeling is a key to digital twin development—both when considering the models which a digital twin maintains of its real‐world complement (“models in digital twin”) and when considering models of the digital twin as a complex (software) system itself.
