Selfing Can Facilitate Transitions between Pollination Syndromes [PDF]

open access: yesThe American Naturalist, 2018
Pollinator-mediated selection on plants can favor transitions to a new pollinator depending on the relative abundances and efficiencies of pollinators present in the community. A frequently observed example is the transition from bee pollination to hummingbird pollination.

Direct and Indirect Effects of Overstory Canopy and Sex-Biased Density Dependence on Reproduction in the Dioecious Shrub Shepherdia canadensis (Elaeagnaceae)

open access: yesDiversity, 2020
This study assessed the reproductive success of a temperate dioecious shrub, Canada buffaloberry, Shepherdia canadensis (L.) Nutt., in central Alberta, Canada, by examining the effects of spatial patterns and overstory canopy on flower and fruit ...

Floral characteristics support nocturnal pollination and pollination syndrome in Barringtonia racemosa

open access: yesEnvironmental and Experimental Biology, 2022
To test for pollination syndrome and to complement records of foraging visitors of an associate mangrove, Barringtonia racemosa (L.) Spreng., aspects of its floral biology were investigated. Phenology and floral rewards (pollen viability, pollen histochemistry and nectar sugar concentration) were focused on owing to their role in plant-pollinator ...

A quantitative review of pollination syndromes: do floral traits predict effective pollinators? [PDF]

open access: yesEcology Letters, 2014
AbstractThe idea of pollination syndromes has been largely discussed but no formal quantitative evaluation has yet been conducted across angiosperms. We present the first systematic review of pollination syndromes that quantitatively tests whether the most effective pollinators for a species can be inferred from suites of floral traits for 417 plant ...

Honeybee Colony Vibrational Measurements to Highlight the Brood Cycle [PDF]

open access: yes, 2015
Insect pollination is of great importance to crop production worldwide and honey bees are amongst its chief facilitators. Because of the decline of managed colonies, the use of sensor technology is growing in popularity and it is of interest to develop ...

Great Diversity of Insect Floral Associates May Partially Explain Ecological Success of Poison Ivy (\u3ci\u3eToxicodendron Radicans\u3c/i\u3e Subsp. \u3ci\u3eNegundo\u3c/i\u3e [Greene] Gillis, Anacardiaceae) [PDF]

open access: yes, 2018
Little is known about insect floral associates of poison ivy (Toxicodendron radicans, Anacardiaceae), despite the species’ ubiquity and importance in nature and society.

Beyond buzz‐pollination – departures from an adaptive plateau lead to new pollination syndromes [PDF]

open access: yesNew Phytologist, 2018
SummaryPollination syndromes describe recurring adaptation to selection imposed by distinct pollinators. We tested for pollination syndromes in Merianieae (Melastomataceae), which contain bee‐ (buzz‐), hummingbird‐, flowerpiercer‐, passerine‐, bat‐ and rodent‐pollinated species.

The importance of pollination and dispersal syndromes for the conservation of Cerrado Rupestre fragments on ironstone outcrops immersed in an agricultural landscape [PDF]

open access: yesNeotropical Biology and Conservation, 2022
Studies on pollination and seed dispersal are essential for the conservation of plant diversity. In this study, we aimed to evaluate the pollination and dispersal syndromes of five fragments of the Cerrado Rupestre immersed in an agricultural landscape ...

Composition and Host-Use Patterns of a Scarab Beetle (Coleoptera: Scarabaeidae) Community Inhabiting the Canopy of a Lowland Tropical Rainforest in Southern Venezuela [PDF]

open access: yes, 2019
The adult scarab beetle fauna of the canopy in a lowland tropical rainforest in southern Venezuela was observed and collected by means of a 42 m-tall tower crane for a complete year.

What Do Nectarivorous Bats Like? Nectar Composition in Bromeliaceae With Special Emphasis on Bat-Pollinated Species

open access: yesFrontiers in Plant Science, 2019
Floral nectar is the most important reward for pollinators and an integral component of the pollination syndrome. Nectar research has mainly focused on sugars or amino acids, whereas more comprehensive studies on the nectar composition of closely related
