How Does Floral Nectar Sugar Concentration Differ between Bat, Bird, and Insect Pollination Syndromes? [PDF]

Floral nectar is the primary reward offered to pollinators by plants and therefore it is an important determinant in plant-pollinator interactions. Global warming and land use changes have significantly reduced pollinator numbers.

Nanoparticles in Periodontology and Implant Dentistry: From Mechanisms to Clinical Applications

Journal of Periodontal Research, EarlyView.
Nanotechnology holds significant promise in improving dental care, yet there is a need for more reliable clinical studies to validate its effectiveness and safety. ABSTRACT Recent advances in nanotechnology are reshaping the landscape of periodontology and implant dentistry, particularly through the application of nanoparticles (NPs).

Putting pollination quality into analyses of floral ecology: testing syndromes through pollinator performance

, 2012
Over recent years, the extent of specialised and generalised plant-pollinator relationships, and the predictive powers of floral traits (often grouped into “pollination syndromes”) as indicators of the most effective pollinators of plant species, have ...

Differences in Pollination Syndromes and the Frequency of Autonomous Delayed Selfing Between Co-flowering Hibiscus poneurus (Sprague and Hutch) and H. flavifolius (Ulbr) from Kenya [PDF]

, 2018
Delayed autonomous selfing offers a mechanism for seed production when pollination levels are low or unpredictable. At Mpala Research Centre (MRC) in Kenya, we examined the relationships between floral attraction, insect visitation, and delayed ...

Molecular evolution of floral development genes in spiral gingers with divergent pollination syndromes

Frontiers in Ecology and Evolution
The evolution of floral traits is a major contributor to plant diversification and pollination specialization. In the Neotropical genus Costus, closely related species exhibit distinct pollination syndromes, offering an opportunity to investigate the ...

Pollinator efficiency, rather than bee decline, explains a shift to hummingbird pollination in tropical montane forests

New Phytologist, EarlyView.
Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

Pollen longevity and viability dataset: an integrated resource for plant research and conservation

New Phytologist, EarlyView.
The most common methods to estimate pollen viability. Summary Pollen viability and longevity are key traits in plant reproduction, with implications for gene flow, crop breeding, and ex situ plant conservation. However, published data on these traits remain dispersed across disciplines, languages, and methods, limiting their accessibility and reuse ...

Data from: Repeated evolution of vertebrate pollination syndromes in a recently diverged Andean plant clade

, 2017
While specialized interactions, including those involving plants and their pollinators, are often invoked to explain high species diversity, they are rarely explored at macroevolutionary scales. We investigate the dynamic evolution of hummingbird and bat
