Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife
Biological Reviews, EarlyView.ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over

Research on load-bearing optimization of non-circular gear based on asymmetric pressure angles
Advances in Mechanical EngineeringTo improve the load-bearing capacity of non-circular gear, a design method with asymmetric pressure angles was constructed. The method for forming tooth profiles of non-circular gear based on a rack with asymmetric pressure angles was studied, the ...

Business Strategy and the Environment, EarlyView.ABSTRACT This study analyses the association between carbon emissions and financial performance in Latin American firms. The scientific literature on this topic is limited, with little evidence available in this geographical region. This study aims to address this research gap by testing hypotheses focused on analysing how Scope 1, 2 and 3 carbon ...

Business Strategy and the Environment, EarlyView.ABSTRACT Circular ecosystems connect diverse actors who collaborate to close resource loops and pursue sustainable goals without centralized control. Such arrangements entail heightened interdependence and uncertainty, making trust, understood as the willingness to accept vulnerability based on positive expectations of others' behavior, a critical ...

Business Strategy and the Environment, EarlyView.ABSTRACT Environmental entrepreneurship and eco‐innovation, although cornerstones in the transition to a sustainable world, form a research nexus that remains largely understudied. We draw on the theory of complexity and the notion of cultural, temporal, and relational complexities to explain the process of eco‐innovation among environmental small ...

Voices From the Coast: Stakeholder Participation and Perception on Creating a Marine Protected Area
Business Strategy and the Environment, EarlyView.ABSTRACT This study explores participatory processes in the context of marine conservation, with a specific focus on recent initiatives undertaken by the Apulia region in Italy to establish a new Marine Protected Area (MPA). Employing a qualitative cross‐sectional methodology, the study investigates how local communities perceive and engage with the ...
