1. Proboscis length has been proposed as a key dimension of plant pollination niches, but this niche space has not previously been explored at regional and global scales for any pollination system. Hawkmoths are ideal organisms for exploring pollinator niches as they are important pollinators in most of the biodiverse regions of the earth and vary...

1. A major challenge in evolutionary ecology is to understand how coevolutionary processes shape patterns of interactions between species at community level. Pollination of flowers with long corolla tubes by long-tongued hawkmoths has been invoked as a showcase model of coevolution. Recently, optimal foraging models have predicted that there might...
Article
Full-text available
Long-tubed hawkmoth-pollinated species present some of the most remarkable examples of floral specialization depending exclusively on long-tongued hawkmoths for sexual reproduction. Nonetheless, long-tongued hawkmoths do not rely exclusively on specialized plants as nectar sources, which may limit sexual reproduction through pollen limitation. Howe...
Article
Full-text available
Inga species present brush-type flower morphology allowing them to be visited by distinct groups of pollinators. Nectar features in relation to the main pollinators have seldom been studied in this genus. To test the hypothesis of floral adaptation to both diurnal and nocturnal pollinators, we studied the pollination ecology of Inga sessilis, with...

Aim The aim of the study was (1) to describe the biodiversity of the sphingid assemblage in a Cerrado area in the Triângulo Mineiro region, south-east of Brazil; (2) to evaluate the seasonal variations in species composition; (3) to compare the faunistic relationships between the Cerrado biome and adjacent ecosystems; and (4) to analyse the biogeog...
Article
Plants are involved in different interactions with animals that may have contrasting effects on their reproductive output. However, as multitrophic interactions are resource-mediated and density-dependent, the frequency at which these interactions occur is modulated by the demographical characteristics of the populations of interacting species. For...
Article
Full-text available
Since Darwin, very long and narrow floral tubes have been known to represent the main floral morphological feature for specialized long-tongued hawkmoth pollination. However, specialization may be driven by other contrivances instead of floral tube morphology. Asclepiads are plants with a complex floral morphology where primary hawkmoth pollination...
Article
Full-text available
Background: Animal pollination is an important ecosystem function and service, ensuring both the integrity of natural systems and human well-being. Although many knowledge shortfalls remain, some high-quality data sets on biological interactions are now available. The development and adoption of standards for biodiversity data and metadata has pro...
Article
Many ecosystems have been modified by humans, creating novel habitats that include human provided resources. Gardens adjacent to native habitats may affect plant-pollinator interactions by altering the determinants of interactions and species specialisation. Here, we characterised a network comprising plants and hummingbirds interacting in a birdwa...

Symbiotic relationships in marine environments are not fixed and can change throughout the animal’s life. This study investigated the ontogeny of symbiosis of the spider crab Libinia ferreirae with the host medusa Lychnorhiza lucerna. We described the type of relationship, the temporal correlation among species and food habits. More than 50% of the...
Article
1. The reproduction of specialised endophagous insects relies on a fine temporal synchronization between the insect and its host plant phenology. 2. Since the spatial distribution and local prevalence of specialised insects depend on both environmental conditions and biotic interactions, in this study, we assessed whether the life cycle of the pred...

Biology and morphological description of a Brazilian weevil in the Genus Eulechriops (Coleoptera: Curculionidae: Conoderinae)
Article
Full-text available
Biological communities are subject to spatiotemporal variations in community structure, i.e., species composition, richness, and abundance. Plant-pollinator interactions are affected by species composition and abundance, so that rapid changes in plant community structure can lead to critical impacts on plant-pollinator interactions at the community...
Article
Full-text available
I was about 10-11 years old and living in the capital, Palmas, of Tocantins State, Northern Brazil, when I first remember seeing a hawkmoth. Tocantins (from the indigenous language Tupiguarani, tukana + tim, means “toucan beak”) is the youngest state of Brazil, founded in 1988, and was named after the river Tocantins, which runs through the entire...
Article
Full-text available
Events of both hybridization and polyploidy are capable of completely restructuring the genome, modifying phenotypic traits and affecting ecological interactions. For plants, these changes may affect floral traits that are important for interactions with pollinators, which could lead to shifts in pollinator behavior and taxa between hybrids/polyplo...
Article
***WE ARE HAPPY TO SEND YOU A COPY OF THE PAPER UNDER REQUEST*** Hermit crabs are ideal organisms for assessing how species that share resources can coexist, as these crustacean species have an intimate relationship with gastropod shells and therefore compete for this particular resource. There is compelling evidence that hermit crabs do not inter...

1. Plant-animal mutualisms are key processes that influence community structure, dynamics, and function. They reflect several neutral and niche-based mechanisms related to plant-animal interactions. 2. However, the strength with which these processes influence community structure depends on functional traits that influence the interactions between...

Background and Aims Large clades of angiosperms are often characterized by diverse interactions with pol-linators, but how these pollination systems are structured phylogenetically and biogeographically is still uncertain for most families. Apocynaceae is a clade of >5300 species with a worldwide distribution. A database representing >10 % of speci...

Hummingbirds are the main pollinators of most bromeliad species, whose nectar traits usually respond to the selective pressures imposed by pollinators. Considering the specialization of hummingbird-pollinated bromeliads, we expect a close relationship between nectar ecophysiology and the needs of the main pollinators. In this sense, we studied the...

Article
Full-text available
Extrafloral nectaries can occur in both vegetative and reproductive plant structures. In many Rubiaceae species in the Brazilian Cerrado, after corolla abscission, the floral nectary continues to secret nectar throughout fruit development originating post-floral pericarpial nectaries which commonly attract many ant species. The occurrence of such n...

Article
Ecological network approaches may contribute to conservation practices by quantifying within-community importance of species. In mutualistic plant-pollinator systems, such networks reflect potential pollination of the plants and a considerable portion of the energy consumption by the pollinators, two key components for each party. Here, we used two...

Darwin foi o primeiro a propor que caracteres florais evoluem como adaptações aos polinizadores. Em seus trabalhos utilizou orquídeas como alguns dos principais exemplos para ilustrar a teoria da evolução através da seleção natural. Contudo, apenas recentemente muitas das hipóteses adaptativas têm sido testadas experimentalmente quantificando-se a...
Article
Full-text available
Some species of long-spurred orchids achieve pollination by a close association with long-tongued hawkmoths. Among them, several Habenaria species present specialized mechanisms, where pollination success depends on the attachment of pollinaria onto the heads of hawkmoths with very long proboscises. However, in the Neotropical region such moths are...

Dioecy is characterized by a complete separation of sexual functions on male and female plants. It has evolved many times in flowering plants and is widespread among distinct Angiosperm families. It is viewed as a reproductive strategy to reduce endogamy, and to promote optimal resource allocation between male and female sexual functions. Neea thei...
Article
Currently, pollination is seen as involving more generalist interactions than specialized ones. Supporting this trend, some nocturnal distylous flowers may also receive floral visitors during the day, and since the latter contribute to fruit set, the pollination system is mixed and less specialized. Common among the Rubiaceae, distyly has been rega...
