Restoration Ecology, EarlyView.Abstract Introduction Across the Mediterranean Basin, land abandonment has opened large areas to passive rewilding, raising questions about the pace and variability of secondary succession in these landscapes and how ecological and abiotic gradients mediate vegetation recovery in post‐agricultural landscapes. Objectives This study aims to quantify long‐

Fiber- and FSO-Protected Connections for Long-Reach TWDM Access Architecture With Fault Protection
IEEE Access, 2020 In this paper, we propose a long-reach star-ring-based timeand wavelength-divisionmultiplexing passive optical network (TWDM-PON) by using fiberand free space optical (FSO)-protected architecture against fiber breakpoint.

People and Nature, Volume 8, Issue 7, Page 2091-2103, July 2026.Abstract The recovery of large carnivores in Europe raises issues related to sharing landscape with humans. Beyond technical solutions, it is widely recognized that social factors also contribute to shaping coexistence. In this context, scholars increasingly stress the need to adopt place‐based approaches by analysing how humans and wildlife interact ...
