Narratives of art-making in chronic fatigue syndrome/ myalgic encephalomyelitis: Three case studies [PDF]

, 2006
This paper explores the narratives of three women who had lived with severe chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) for many years, and who engaged in art-making as a leisure activity rather than for psychotherapy.

Identification of transcription factors controlling floral morphology in wild Petunia species with contrasting pollination syndromes [PDF]

The Plant Journal, 2020
SummaryAdaptation to different pollinators is an important driver of speciation in the angiosperms. Genetic approaches such as QTL mapping have been successfully used to identify the underlying speciation genes. However, these methods are often limited by widespread suppression of recombination due to divergence between species.

Impatiens smetsiana, another example of convergent evolution of flower morphology in Impatiens [PDF]

Plant Ecology and Evolution, 2022
Background and aims – The genus Impatiens is known for its enormous convergent phenotypic adaptation, with similar floral traits having independently evolved in distantly related lineages.

Oakleaf: an S locus-linked mutation of Primula vulgaris that affects leaf and flower development [PDF]

, 2015
•In Primula vulgaris outcrossing is promoted through reciprocal herkogamy with insect-mediated cross-pollination between pin and thrum form flowers. Development of heteromorphic flowers is coordinated by genes at the S locus.

Reproductive Biology and Breeding Systems of Two Opisthopappus Endemic and Endangered Species on the Taihang Mountains

Plants, 2023
Opisthopappus is a perennial, endemic herb of the Taihang Mountains in China. Two species of this genus (O. longilobus and O. taihangensis) are important wild genetic resources for Asteraceae; however, their reproductive biology has been lacking until ...

Combined stress from parasites, pesticides and lack of flowers drives bee declines [PDF]

, 2015
Bees are subject to numerous pressures in the modern world. The abundance and diversity of flowers has declined, bees are chronically exposed to cocktails of agrochemicals, and they are simultaneously exposed to novel parasites accidentally spread by ...

A global review of pollination syndromes: a response to ollerton et al. 2015 [PDF]

, 2015
In a recent literature review, we demonstrated that the evolution of floral traits is driven by adaptation to the most effective pollinators. In a critique of this study, Ollerton et al.

The importance of flower visitors not predicted by floral syndromes

South African Journal of Botany, 2009
AbstractFlower visitors that do not fit a perceived floral syndrome are often over-looked and deemed unimportant. In Tritoniopsis revoluta, an irid with a very long corolla tube conforming to the long proboscid fly pollination syndrome, we determine visitation rates of bees and long proboscid flies, as well as ascertain whether bees could be important ...

Identification of major quantitative trait loci underlying floral pollination syndrome divergence in Penstemon [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2014
Distinct floral pollination syndromes have emerged multiple times during the diversification of flowering plants. For example, in western North America, a hummingbird pollination syndrome has evolved more than 100 times, generally from within insect-pollinated lineages.

Sending private messages: Floral ultraviolet signals are correlated with pollination syndromes in Erica

Journal of Pollination Ecology, 2021
The presence of ultraviolet (UV, wavelengths between 300-400 nm) reflectance in insect-pollinated flowers has been linked to pollination efficiency and pollination shifts, but little is known about its prevalence and function in other pollination systems and African species.
