Wild bees preferentially visit Rudbeckia flower heads with exaggerated ultraviolet absorbing floral guides

open access: yesBiology Open, 2014
Here, we report on the results of an experimental study that assessed the visitation frequency of wild bees to conspecific flowers with different sized floral guides.

Bees from an Island in the Delta of the Americas (Maranhão state, Brazil) and their Floristic Interactions

open access: yesSociobiology, 2021
Surveys of the bee fauna on islands are scarce due to the difficult access to the study area. Thus, the current study intended to establish the species of bees present in an island of the Delta of the Americas, called Grande do Paulino, Tutóia, Maranhão.

Pan traps: An effective tool for monitoring phenological changes in insect floral visitors and their relationship with floral resources in a coastal Mediterranean forest

open access: yesEcological Indicators
Precise monitoring of insect floral visitors and their relationship with floral resources throughout the flowering season provides baseline information to help us understand long-term changes in plant-pollinator interactions and improve pollinator ...

The role of facultatively nectarivorous birds as pollinators of Anarthrophyllum desideratum in the Patagonian steppe: a geographical approach

open access: yesEcología Austral, 2017
The endemic shrub Anarthrophyllum desideratum appears to be the only ornithophilous plant offering nectar as reward in the extensive Patagonian steppe.

Understanding the Complex Structure of a Plant-Floral Visitor Network from Different Perspectives in Coastal Veracruz, Mexico

open access: yesSociobiology, 2013
Our premise was to understand the basic structure of the flower-flower visitor community at La Mancha in Veracruz, Mexico. We used network analyses to study the structure of this community. In particular, to analyze, (1) if flower color and shape (“as a

Pollination by hummingbirds of Vriesea gigantea (Bromeliaceae) populations in Southern Brazil

open access: yesRodriguésia, 2020
The pollination syndrome hypothesis usually does not successfully apply to the diversity of floral phenotypes or help predict the pollinators of most plant species.

Floral visitors of canola (Brassica napus L.) hybrids in Cerrado Mineiro region, Brazil

open access: yesArquivos do Instituto Biológico, 2019
: The objective of this study was to verify floral visitors of canola in the Triângulo Mineiro region, Minas Gerais, Brazil. A completely randomized plot design with two hybrids and 10 replicates was used, totaling 20 plots. The survey of floral visitors

Are pollination syndromes useful predictors of floral visitors in Tasmania? [PDF]

open access: yesAustral Ecology, 2000
Abstract Diurnal visitors to the flowers of many native plant species were identified in a wide range of Tasmanian sclerophyllous vegetation between September 1996 and April 1997. These foraging profiles were analysed to determine whether they were characteristic of various floral morphologies in predictable ways.

The rate of visitation by Amazilia fimbriata (Apodiformes: Trochilidae) influences seed production in Tillandsia stricta (Bromeliaceae)

open access: yesZoologia (Curitiba), 2015
Legitimate flowers visitors pollinate the flower during the visit and thus influence the production of fruits and seeds. We tested whether the visitation rate of potential pollinators is associated with the amount of seeds per fruit produced by the self ...

Multiomics Analyses Reveal an Essential Role of Tryptophan in Treatment of csDMARDs in Rheumatoid Arthritis

open access: yesAdvanced Science, EarlyView.
Rheumatoid arthritis is a disease characterized by joint inflammation. Approximately 50% of patients show insufficient response to traditional synthetic disease‐modifying antirheumatic drugs. This study aims to elucidate differential molecular profiles of the mechanisms underlying drug responses through multi‐omics strategy.
