Bee Body Size and Foraging Behavior Predict the Pollination Role of Bees in a Buzz‐Pollinated Plant Community [PDF]

Ecology and Evolution
Buzz pollination has been studied for over a century, yet the drivers shaping plant–pollinator interactions at the community level remain poorly understood.

Requerimentos de polinização da goiabeira Pollination requeriments of guava [PDF]

Ciência Rural, 2007
A goiabeira (Psidium guajava) é uma planta muito cultivada no Nordeste brasileiro, onde seus frutos têm elevada importância econômica, porém poucas pesquisas referem-se aos seus requerimentos de polinização.

3D pollination biology using micro-computed tomography and geometric morphometrics in Theobroma cacao. [PDF]

Appl Plant Sci, 2023
Abstract Premise Imaging technologies that capture three‐dimensional (3D) variation in floral morphology at micro‐ and nano‐resolutions are increasingly accessible. In herkogamous flowers, such as those of Theobroma cacao, structural barriers between anthers and stigmas represent bottlenecks that restrict pollinator size and access to reproductive ...

Fine-tuning the buzz: comparing visitation frequency and pollination effectiveness in plant-pollinator networks. [PDF]

New Phytol
Summary Ecological network approaches have advanced our understanding of how species interactions influence community and evolutionary dynamics. However, a key limitation is that most network analyses rely solely on visitation data, often overlooking functional aspects of interactions.

A critical analysis of the potential for EU Common Agricultural Policy measures to support wild pollinators on farmland. [PDF]

J Appl Ecol, 2020
To conserve pollinators and help protect pollination services, our expert elicitation highlights the need to create a variety of interconnected, well‐managed habitats that complement each other in the resources they offer. To achieve this the Common Agricultural Policy post‐2020 should take a holistic view to implementation that integrates the ...

Bract size affects resource availability and fruit set in a hummingbird-pollinated plant with distyly polymorphism. [PDF]

Plant Biol (Stuttg)
In Psychotria poeppigiana, larger bracts honestly signal greater nectar availability but have higher mortality, while smaller bracts produce more fruit, revealing a surprising trade‐off and hints of sexual role specialization in this distylous species. Abstract Plants can use non‐floral signals to advertise the presence of resources to pollinators. The

Investigating the effects of fire on pollinator-dependent distyly polymorphism. [PDF]

Plant Biol (Stuttg)
While fire causes some morphological changes in pollinator‐dependent distylous flowers, most traits related to attraction, reward, and stigma‐anther reciprocity remain unaffected, ensuring intermorph pollen transfer and maintaining the floral polymorphism.
