Oikos, EarlyView.Fruit colour has long fascinated scientists and is widely considered an evolutionary adaptation to attract both avian and mammalian frugivores. While fleshy fruits play a key role in plant–animal interactions by promoting seed dispersal, the functional significance of colour variation, particularly multicoloured displays during ripening, remains poorly

Oikos, EarlyView.Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Population recovery of an endangered macaw enhances long‐distance seed dispersal via stomatochory
Oikos, EarlyView.Seed dispersal by large, mobile vertebrates plays a key role in shaping plant spatial dynamics and community structure. However, how variation in animal population size influences the magnitude and spatial scale of seed dispersal remains poorly understood.

Oikos, EarlyView.The traditional view of river basins as linear corridors has led to numerous studies examining the effects of stream size on aquatic communities. However, similar‐sized streams may harbor distinct faunal assemblages depending on their spatial context within the basin. Headwater tributaries (HTs) that flow into small streams, in the periphery of basins,

People and Nature, EarlyView.Abstract Pastoral practices remain a widespread economic activity across European mountain regions. However, the viability of this activity may be threatened by the recovery of large wild vertebrates associated with passive rewilding, leading to the so‐called human–wildlife conflicts.
