Plant-pollinator interaction in a peatland ecosystem in Minas Gerais, Brazil
Revista Espinhaço, 2023 The Espinhaço Mountain Range is an important complex of mountains and plateaus within the Brazilian Cerrado. Within this area we can found peatlands ecosystem, which are important carbon reservoirs and home of a variety of plants and their floral ...

Mutualist- and antagonist-mediated selection contribute to trait diversification of flowers [PDF]
PeerJ, 2022 Flowers are generally short-lived, and they all face a multidimensional challenge because they have to attract mutualists, compel them to vector pollen with minimal investment in rewards, and repel floral enemies during this short time window.

Flowering and pollination ecology of Cleistocactus baumannii (Cactaceae) in the Brazilian Chaco: pollinator dependence and floral larceny [PDF]
Acta Botânica Brasílica, 2020 Cleistocactus baumannii is the only ornithophilous cactus species in the Brazilian Chaco. In addition, this species of Cactaceae invests heavily in flowering in the ecoregion.

Diversity of floral visitors to sympatric Lithophragma species differing in floral morphology [PDF]
Oecologia, 2009 Most coevolving relationships between pairs of species are embedded in a broader multispecific interaction network. The mutualistic interaction between Lithophragma parviflorum (Saxifragaceae) and its pollinating floral parasite Greya politella (Lepidoptera, Prodoxidae) occurs in some communities as a pairwise set apart from most other interactions in ...

Pollination of Adenocalymma bracteatum (Bignoniaceae): floral biology and visitors [PDF]
Neotropical Entomology, 2010 Adenocalymma bracteatum is a shrub of dense foliage and yellow flowers, easily found on grasslands areas in Central Brazil. The aim of this study was to determine the reproductive biology and the flower visitors of A. bracteatum in a pasture area nearby Ivinhema city, MS (Brazil). The flowering peak occurs in winter.

Floral biology of Stachytarpheta maximiliani Scham. (Verbenaceae) and its floral visitors [PDF]
Revista Brasileira de Entomologia, 2006 This study describes the reproductive system of Stachytarpheta maximiliani (Verbenaceae), including its floral biology, nectar and pollen availability and insect foraging patterns, identifying whose species act as pollinators. It was carried out in a Brazilian Atlantic rain forest site.

Floral Specialization: what do floral attributes and floral visitors tell us?
, 2022 Abstract Floral traits may either facilitate or constrain the gathering of food resources by certain animals. We therefore sought here to define the floral specialization levels of 19 plant species visited by foraging insects, based on their floral attributes and on the behaviors of their respective insect visitors.

Effects of floral metal accumulation on floral visitor communities: Introducing the elemental filter hypothesis [PDF]
American Journal of Botany, 2015 • Premise of the study: For plant species that occur in heavy‐metal‐rich soil, floral metal accumulation may produce an “elemental filter” that reduces pollinator visitation rate and species richness and changes pollinator species composition relative to closely related species growing on normal soils.

Floral scents repel facultative flower visitors, but attract obligate ones [PDF]
Annals of Botany, 2010 Biological mutualisms rely on communication between partners, but also require protective measures against exploitation. Animal-pollinated flowers need to attract pollinators but also to avoid conflicts with antagonistic consumers. The view of flower visitors as mutualistic and antagonistic agents considers primarily the plants' interest.

PLoS ONE, 2020 In increasingly urban landscapes, the loss of native pollen and nectar floral resources is impacting ecologically important pollinators. Increased urbanization has also brought about the rise of urban gardens which introduce new floral resources that may
