Maruyama, Pietro Kiyoshi; Vizentin-Bugoni, Jeferson; Sonne, Jesper; Martín González, Ana M.; Schleuning, Matthias; Araujo, Andréa Cardoso deAim: To investigate the role of alien plants in mutualistic plant-hummingbird networks, assessing the importance of species traits, floral abundance and insularity on alien plant integration. Location: Mainland and insular Americas. Methods: We used species-level network indices to assess the role of alien plants in 21 quantitative plant-hummingbird networks where alien plants occur. We then evaluated whether p...
High proportion of smaller ranged hummingbird species coincides with ecological...
Sonne, Jesper; Martín González, Ana M.; Maruyama, Pietro Kiyoshi; Sandel, Brody S.; Vizentin-Bugoni, Jeferson; Schleuning, Matthias; Abrahamczyk, StefanEcological communities that experience stable climate conditions have been speculated to preserve more specialized interspecific associations and have higher proportions of smaller ranged species (SRS). Thus, areas with disproportionally large numbers of SRS are expected to coincide geographically with a high degree of community-level ecological specialization, but this suggestion remains poorly supported with ...
Flora, fenologia de floração e polinização em capões do Pantanal Sul Mato Gross...
Araujo, Andréa Cardoso deOs objetivos deste estudo são conhecer as espécies vegetais que ocorrem em capões, a variação na disponibilidade de flores ao longo do ano, as síndromes de polinização e as espécies de flores exploradas por beija-flores neste ambiente. Todas as espécies em flor foram registradas em 3-5 capões diferentes a cada mês (totalizando 52 capões), num período de 13 meses no Pantanal do MirandaAbobral. As espécies florid...
