Processes entangling interactions in communities: forbidden links are more important than abundance in a hummingbird-plant network.
TL;DR: Estimating the relative importance of species abundance and forbidden links in structuring a hummingbird–plant interaction network from the Atlantic rainforest in Brazil suggests that species abundance can be a less important driver of species interactions in communities than previously thought.
Journal ArticleDOI
Morphological and Spatio-Temporal Mismatches Shape a Neotropical Savanna Plant-Hummingbird Network
Pietro K. Maruyama,Pietro K. Maruyama,Jeferson Vizentin-Bugoni,Genilda M. Oliveira,Paulo Eugênio Oliveira,Bo Dalsgaard +5 more
TL;DR: It is proposed that traits matter more in tropical plant–hummingbird networks than in less specialized systems, and future research could employ geographic or taxonomic cross-system comparisons contrasting networks with known differences in level of specialization.
Journal ArticleDOI
Influences of sampling effort on detected patterns and structuring processes of a Neotropical plant–hummingbird network
Jeferson Vizentin-Bugoni,Jeferson Vizentin-Bugoni,Pietro K. Maruyama,Vanderlei J. Debastiani,L. da S. Duarte,Bo Dalsgaard,Marlies Sazima +6 more
TL;DR: It is indicated that in networks strongly constrained by species traits, such as plant-hummingbird networks, even small sampling is sufficient to detect their relative importance for the frequencies of interactions, and encouraged the use of quantitative metrics little influenced by sampling when performing spatio-temporal comparisons.
Journal ArticleDOI
Opposed latitudinal patterns of network‐derived and dietary specialization in avian plant–frugivore interaction systems
Bo Dalsgaard,Matthias Schleuning,Pietro K. Maruyama,D. Matthias Dehling,Jesper Sonne,Jeferson Vizentin-Bugoni,Thais B. Zanata,Jon Fjeldså,Katrin Böhning-Gaese,Carsten Rahbek +9 more
TL;DR: The results highlight the necessity of comparing different scales of biotic specialization for a better understanding of geographical patterns of specialization in resource-consumer interactions.

TL;DR: Higher levels of specialization and modularity were associated with species-rich communities and communities in which closely related hummingbirds visited distinct sets of flowering species, indicating a tighter co-evolutionary association between hummingbirds and their plants than in previously studied plant–bird mutualistic systems.
