RESUMO O futuro da biodiversidade das florestas tropicais e dos serviços ambientais prestados por este ecossistema está intrinsecamente ligado a nossa habilidade de entender as mudanças deflagradas pela fragmentação habitats outras forças que dirigem dinâmica biológica em paisagens antrópicas. Neste artigo nós reunimos evidências empíricas teóricas para argumentar os efeitos borda deflagram um processo sucessional rápido inevitável, o qual conduz maioria fragmentos neotropicais direção...
What governments can do to safeguard pollination services
Functional diversity has been postulated to be critical for the maintenance of ecosystem functioning, but way it can disrupted by human-related disturbances remains poorly investigated. Here we test hypothesis that habitat fragmentation changes relative contribution tree species within categories reproductive traits (frequency traits) and reduces functional assemblages. The study was carried out in an old severely fragmented landscape Brazilian Atlantic forest. We used published information...
Despite many studies on fragmentation of tropical forests, the extent to which plant and animal communities are altered in small, isolated forest fragments remains obscure if not controversial. We examined hypothesis that alters relative abundance tree species with different vegetative reproductive traits. In a fragmented landscape (670 km(2) ) Atlantic Forest northeastern Brazil, we categorized 4056 trees 182 by leafing pattern, phenology, morphology seeds fruit. calculated traits 50 1-ha...
Global climate change alters the dynamic of natural ecosystems and directly affects species distributions, persistence diversity. The impacts may lead to dramatic changes in biotic interactions, such as pollination seed dispersal. Life history traits are extremely important consider vulnerability a change, producing more robust models than those based primarily on distributions. Here, we hypothesized that rising temperatures aridity will reduce suitable habitats for endemic flora Caatinga,...
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...
Many studies in the past decade, mostly temperate countries, have documented effects of habitat loss and fragmentation on species richness, composition, abundance behaviour pollinators. Changes landscape structure are considered to be primary causes limitation pollination services agricultural systems. Here, we review evidence general patterns as well gaps knowledge that could used support development policies for pollinator conservation restoration degraded landscapes. Our results indicate...
Abstract Caatinga vegetation continues to be converted into mosaics of secondary forest stands, but the affect this process on biodiversity has not yet been examined. We used 35 regenerating and old‐growth stands examine recovery plant assemblages subsequent slash‐and‐burn agriculture cattle ranching/pasture in northeastern Brazil. Plant were contrasted terms community structure (stem density/basal area/species richness/diversity), functional (leaf habit/reproductive traits) taxonomic...
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...
In this study, we evaluated the phenological patterns (vegetative and reproductive) of Calotropis procera (Apocynaceae-Asclepiadoideae) in Brazil, comparing its phenology an area where it is invasive with that observed areas to which native. Phenological observations were carried out over a 24-month period at sites around caatinga (shrublands). We estimated relative frequency each phenophase, documented dramatic difference between phenophases terms pattern reproductive . The continuous...
The conservation status of pollinators and pollination in Latin America (LA) is reviewed. knowledge regarding native managed (e.g., honeybee stingless bees) services was synthetized, the guidelines to improve opportunities for are provided, considering threats perspectives from traditional local knowledge. analysis indicates that diverse large-scale agriculture, deforestation, overuse agrochemicals) linked with pollinator decline, which affect reproduction most plants yields many crops.
