Building bridges between environmental and political agendas is essential nowadays in face of the increasing human pressure on natural environments, including wetlands. Wetlands provide critical ecosystem services for humanity can generate a considerable direct or indirect income to local communities. To meet many sustainable development goals, we need move our trajectory from current destructive wiser wetland use. The article contain proposed agenda Pantanal aiming improvement public policy...
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 The temporal dynamics of plant phenology and pollinator abundance across seasons should influence the structure plant–pollinator interaction networks. Nevertheless, such are seldom considered, especially for diverse tropical Here, we evaluated variation four networks in two seasonal ecosystems Central Brazil (Cerrado Pantanal). Data were gathered on a monthly basis over 1 year each network. We characterized shifts interactions, using temporally discrete predicted that greater floral...
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...
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...
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...
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 To investigate the role of alien plants in mutualistic plant–hummingbird networks, assessing importance species traits, floral abundance and insularity on plant integration. Location Mainland insular Americas. Methods We used species‐level network indices to assess 21 quantitative networks where occur. then evaluated whether including previous adaptations bird pollination, predict these roles. Additionally, for a subset which data were available, we tested this relates Finally,...
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...
Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys biodiversity inventories. Atlantic Forest, most endangered ecosystems world, have high endemism radiated recently Pliocene. We aimed to (1) compile an extensive Forest data set on vascular, non-vascular plants (including hemiepiphytes), lichen epiphyte species occurrence abundance; (2) describe distribution order indicate future sampling efforts. Our work presents first with information abundance...
Summary When describing plant–animal interaction networks, sampling can be performed using plant‐ or animal‐centred approaches. Despite known effects of on network structure, how samplings affect the estimates β‐diversity across networks is still unresolved. We investigated method affects assessment interactions, turnover and rewiring. contrasted methods applied to pollination habitats in a heterogeneous tropical landscape, Pantanal Wetlands. also asked whether plant traits influence...
Space and time promote variation in network structure by affecting the likelihood of potential interactions. However, little is known about relative roles ecological biogeographical processes determining how species interactions vary across space time. Here we study spatiotemporal predator-prey interaction networks formed anurans arthropods test for effects prey availability patterns, information that often absent limits understanding determinants structure. We found dissimilarity between...
We investigated the localization of carbohydrate residues on surface structures microfilariae Wuchereria bancrofti and Brugia malayi, using a panel 10 different gold-labeled lectins chitinase. The sheath, structure that encloses microfilariae, is not homogeneous structure, presenting two clearly distinct layers. outer layer more electron dense was labeled with lectins. inner less intensely lectins, especially those recognize D-galactose N-acetyl-D-galactosamine. Small differences were...
ABSTRACT The habit, shade-tolerance and dispersal agent of 19 bromeliad species were studied in a rainforest community order to relate specific traits the spatial occurrence species. Highest density was found riparian forest (RF), followed by restinga scrub (RE), rocky shore (RS) dense canopy (DF). Terrestrial bromeliads occurred open sites (RE RS), epiphytes absent RS facultative occupied all four habitats. Bird-dispersed upper canopy, whereas those dispersed mammals low profile. Bromeliads...
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...
