Local environment and fragmentation by drought and damming shape different comp...
Martelo, J.; Gkenas, C.; Ribeiro, D.; Alves, M.J.; Ribeiro, F.; Cucherousset, J.; Gago, João; Magalhães, M.F.Pool refuges are critical for maintaining stream fish diversity in increasingly intermittent streams. Yet, the patterns and drivers of beta diversity of native and non-native fish in pool refuges remain poorly known. Focusing on Mediterranean streams, we decomposed beta diversity of native and non-native fish into richness difference (RichDiff) and species replacement (Repl), and local (LCBD, LCBDRichDiff and L...
Long term patterns in the late summer trophic niche of the invasive pumpkinseed...
Gkenas, Christos; Magalhães, M. F.; Cucherousset, J.; Domingos, Isabel; Ribeiro, FilipeQuantifying the trophic dynamics of invasive species in novel habitats is important for predicting the success of potential invaders and evaluating their ecological effects. The North American pumpkinseed sunfish Lepomis gibbosus is a successful invader in Europe, where it has caused negative ecological effects primarily through trophic interactions. Here, we quantified variations in the late summer trophic nic...
