An exploratory study of the functional significance of the floral secretory structures in two Miconia species (Melastomataceae) [PDF]

Anais da Academia Brasileira de Ciências
Aiming to verify whether the diversity of secretory structures with their respective exudates are or not responsible for the attendance of floral visitors in Miconia species, the floral secretory structures of two Amazonian species of Miconia were ...

Reproductive biology and flower-visitor interactions of two bromeliad species from the Brazilian Atlantic Forest [PDF]

Plant Ecology and Evolution, 2022
Background and aims – The Bromeliaceae family has great importance in the maintenance of neotropical communities. In the Brazilian Atlantic Forest, bromeliads are among the major groups responsible for maintaining the local flora and fauna and ...

Discovering new floral visitors of four Chilean endemic orchids [PDF]

Gayana (Concepción), 2019
Orchidaceae is a diverse group with conservation issues all over the World. Due to its endangered situation, knowledge about its reproductive biology is needed to plan conservation strategies. We conducted a study during October 2016 and October 2017 in Maule region, Chile, and discovered the following unreported interactions: Colletes seminitidus ...

How pollinator visits are affected by flower damage and ants presence in Ipomoea carnea subs. fistulosa (Martius and Choise) (Convolvulaceae)?

Brazilian Journal of Biology, 2019
This study aimed to evaluate the effects of florivory and of the patrolling ants associated to EFNs-extrafloral nectaries, on the frequency of floral visitors, using the specie Ipomoea carnea subs. fistulosa (Martius and Choise) in Caatinga area.

Non-Additive Effects of Genotypic Diversity Increase Floral Abundance and Abundance of Floral Visitors

PLoS ONE, 2010
In the emerging field of community and ecosystem genetics, genetic variation and diversity in dominant plant species have been shown to play fundamental roles in maintaining biodiversity and ecosystem function. However, the importance of intraspecific genetic variation and diversity to floral abundance and pollinator visitation has received little ...

Survey dataset on mutualistic interactions among Euterpe edulis Mart. (Arecaceae) and floral and frugivorous visitors considering influence of neighborhood plant density and availability of resources

Data in Brief, 2018
The data are supporting the research article “Effects of neighborhood on pollination and seed dispersal of a threatened palm” (Santos et al., 2018). We recorded through focal observation mutualistic interactions with floral and frugivorous visitors and ...

Seasonal variation in the response of a monoecious crop to increased temperature and fertilizers

Frontiers in Plant Science, 2022
Climate warming may affect the performance of plants directly through altering vegetative or reproductive traits, and indirectly through modifying interactions with their pollinators.

Relationship between floral traits and floral visitors in two coexisting Tecoma species (Bignoniaceae)

Plant Systematics and Evolution, 2011
In this paper, we studied the floral biology of Tecoma fulva ssp. garrocha and T. stans in Vaqueros (Salta, Argentina), where both species coexist. We tested the idea that floral traits are associated with the pollinator types that visit them. According to our results, T. fulva ssp.

Aggregate enantiostyly: Floral visitor interactions with a previously unreported form of floral display

Journal of Pollination Ecology, 2018
Floral herkogamy, or the spatial separation of reproductive structures, plays an important role in the evolution of plant mating systems. One form of herkogamy is enantiostyly, or the alternate presentation of stigmas to the left and right of the floral axis.
