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.

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

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 ...

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.

Spatiotemporal trends in floral visitation and interaction networks reveal shifting niches for bats in a Neotropical savanna

Journal of Animal Ecology, Volume 92, Issue 7, Page 1442-1455, July 2023., 2023
The article reveals that the temporal and spatial axes are important drivers of the floral‐visitor niche of anthophilous bats in a Neotropical savanna, defining the structure of their interaction networks with plants. These findings may aid in the management of the endangered Cerrado bat Lonchophylla dekeyseri. Abstract Flower‐vising bats are important

Sleeping accommodations for researchers increase the likelihood of biodiversity inventories in protected areas 在保护区内为科研人员提供住所，可增加创建生物多样性名录的可能性

Integrative Conservation, Volume 2, Issue 1, Page 62-68, March 2023., 2023
Biodiversity assessments are needed to better understand biodiversity distribution and threats in parks. Our results showed that arthropod inventories are more likely if park accommodations are available for researchers. Small investments in providing accommodations may increase biodiversity assessments in parks.
