We reviewed the occurrences and distributional patterns of migratory species birds in Brazil. A was classified as when at least part its population performs cyclical, seasonal movements with high fidelity to breeding grounds. Of 1,919 recorded Brazil, 198 (10.3%) are migratory. these, 127 (64%) were Migratory 71 (36%) Partially Migratory. few (83; 4.3%) Vagrant eight (0,4%) could not be defined due limited information available, or conflicting data.
Large-scale geographical patterns of biotic specialization and the underlying drivers are poorly understood, but it is widely believed that climate plays an important role in determining specialization. As climate-driven range dynamics should diminish local adaptations favor generalization, one hypothesis contemporary determined by degree past climatic instability, primarily Quaternary climate-change velocity. Other prominent hypotheses predict either or species richness affect To gain...
Abstract Aim To investigate the association between hummingbird–plant network structure and species richness, phylogenetic signal on species' interaction pattern, insularity historical current climate. Location Fifty‐four communities along a c . 10,000 km latitudinal gradient across A mericas (39° N –32° S ), ranging from sea level to 3700 m a.s.l., located mainland islands covering wide range of climate regimes. Methods We measured specialization modularity in mutualistic plant–hummingbird...
Abstract Aim Among the world's three major nectar‐feeding bird taxa, hummingbirds are most phenotypically specialized for nectarivory, followed by sunbirds, while honeyeaters least taxa. We tested whether this phenotypic specialization gradient is also found in interaction patterns with their floral resources. Location Americas, Africa, Asia and Oceania/Australia. Methods compiled networks between birds resources 79 hummingbird, nine sunbird 33 honeyeater communities. Interaction was...
Scientists have long been trying to understand why the Neotropical region holds highest diversity of birds on Earth. Recently, there has increased interest in morphological variation between and within species, how climate, topography, anthropogenic pressures may explain affect phenotypic variation. Because data are not always available for many species at local or regional scale, we limited our understanding intra- interspecies spatial Here, present ATLANTIC BIRD TRAITS, a set that includes...
Interactions between species are influenced by different ecological mechanisms, such as morphological matching, phenological overlap and abundances. How these mechanisms explain interaction frequencies across environmental gradients remains poorly understood. Consequently, we also know little about the that drive geographical patterns in network structure, complementary specialization modularity. Here, use data on morphologies, phenologies abundances to hummingbirds plants at a large scale....
Abstract Functional traits can determine pairwise species interactions, such as those between plants and pollinators. However, the effects of biogeography evolutionary history on trait‐matching trait‐mediated resource specialization remain poorly understood. We compiled a database 93 mutualistic hummingbird–plant networks (including 181 hummingbird 1,256 plant species), complemented by morphological measures bill floral corolla length. divided hummingbirds into their principal clades used...
Abstract Aim Species interaction networks are known to vary in structure over large spatial scales. We investigated the hypothesis that environmental factors affect network by influencing functional diversity of ecological communities. Notably, we expect more functionally diverse communities form with a higher degree niche partitioning. Location: Americas. Time period: Current. Major taxa studied: Hummingbirds and their nectar plants. Methods used dataset comprising 74 quantitative...
Abstract Aim We examined the effects of space, climate, phylogeny and species traits on module composition in a cross‐biomes plant–hummingbird network. Location Brazil, except Amazonian region. Methods compiled 31 local binary networks, combining them into one metanetwork. conducted modularity analysis tested relationship between species’ membership with traits, geographical location, climatic conditions range sizes, employing random forest models. fitted reduced models containing groups...
Ecological communities that experience stable climate conditions have been speculated to preserve more specialized interspecific associations and higher proportions of smaller ranged species (SRS). Thus, areas with disproportionally large numbers SRS are expected coincide geographically a high degree community-level ecological specialization, but this suggestion remains poorly supported empirical evidence. Here, we analysed data for hummingbird resource range size, contemporary climate, Late...
Foi investigada a fenologia e os visitantes florais de espécies da família Bromeliaceae em uma área Mata Atlântica, no Parque Estadual Intervales, Sudeste brasileiro. Os táxons estudados pertencem aos gêneros Tillandsia L. (3 spp.), Vriesea Lindl. (5 Aechmea Ruiz & Pav. Billbergia Thunb. (1 sp.) Nidularium Lem. (2 spp.). Foram estabelecidas transecções amostrais áreas com diferentes estádios sucessionais, onde foi registrada localização dos indivíduos nos estratos vegetação realizados censos...
Cacao agroforestry have been considered as biodiversity-friendly farming practices by maintaining habitats for a high diversity of species in tropical landscapes. However, little information is available to evaluate whether this agrosystem can maintain functional diversity, given that agricultural changes affect the components, but not taxonomic one (e.g., richness). Thus, considering traits improve understanding impacts on biodiversity. Here, we measured (functional richness-FD,...
Urbanization has reshaped the distribution of biodiversity on Earth, but we are only beginning to understand its effects ecological communities. While urbanization may have homogenization strong enough blur large-scale patterns in interaction networks, urban community still be associated with climate gradients reflecting biogeographical processes. Using 103 hummingbird-plant mutualistic networks across continental Americas, including 176 hummingbird and 1,180 plant species, asked how affects...

The maintenance of green areas within cities is essential for promoting urban biodiversity and species interactions. Here, we evaluated the interactions between hummingbirds their visited plants over course a year in an park Barreiras, western Bahia, Brazil. Each month, from October 2018 to September 2019, recorded hummingbird species, they visit, agonistic We 748 legitimate visits by six five plant species. Most (60%) flowered continuously, most were rainy season when network was also more...
