How 1st‐Tier Suppliers Respond to Green Public Procurement Policies: An Empirical Analysis

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This article analyses how 1st‐tier suppliers to public organisations respond operationally to Green Public Procurement (GPP) policies. Through a multiple case study of 12 Italian firms operating in different sectors, we develop a classification of suppliers' responses, identifying two interrelated macro‐types: internal operations realignment ...

The dual influence of top‐down and bottom‐up processes on a mesopredator and the consequences for prey

Ecography, EarlyView.
Ecosystem dynamics are shaped by interacting top‐down and bottom‐up processes, yet their relative importance may vary through time following disturbances such as disease outbreaks and changes in apex predator communities. Using a 52‐year time series in south‐central Sweden, we examined how disease, apex predators, and prey availability jointly impact a
