Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Herkogamy and its effects on mating patterns in Arabidopsis thaliana. [PDF]

open access: yesPLoS ONE, 2013
The evolution of mating systems, which exhibit an extraordinary diversity in flowering plants, is of central interest in plant biology. Herkogamy, the spatial separation of sexual organs within flowers, is a widespread floral mechanism that is thought to

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

open access: yesJournal 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.

Image_4_Different influences of phylogenetically conserved and independent floral traits on plant functional specialization and pollination network structure.jpeg

open access: yes, 2023
Plant specialization and pollination network structure play important roles in community assembly. Floral traits can mediate plant–pollinator interactions and thus have important impacts on nestedness and modularity of pollination network.

Psychiatric and Cognitive Features in Italian Women With the FMR1 Premutation: A Comprehensive Assessment Using SCID‐5 and Standardized Cognitive Measures

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Women with the FMR1 premutation (PM) are at increased risk for fragile X‐associated conditions (FXPAC), including cognitive and psychiatric features collectively termed fragile X‐associated neuropsychiatric disorders (FXAND). This study is the first to systematically investigate cognitive and psychiatric features in Italian female premutation ...

Pollination and seedling ecology of Decalepis hamiltonii Wight & Arn. (Periplocaceae), a commercially important, endemic and endangered species

open access: yesJournal of Threatened Taxa, 2009
Decalepis hamiltonii is a woody climber and annual bloomer. The flowers are characterized by nectariferous coralline corona, gynostegium and pollinia containing tetrads. The floral features such as greenish white corolla, mild fragrance, flat-shape for

New genomic resources and comparative analyses reveal differences in floral gene expression in selfing and outcrossing Collinsia sister species

open access: yesG3: Genes, Genomes, Genetics, 2021
The evolutionary transition from outcross- to self-fertilization is one of the most common in angiosperms and is often associated with a parallel shift in floral morphological and developmental traits, such as reduced flower size and pollen to ovule ...

A Global Prospective Harmonization Framework for Suicidality, Anhedonia, and Obsessive‐Compulsive Symptoms in Psychiatric Genetic Studies: A Cross‐Continental Study Within the Ancestral Population Network

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT This study aims to prospectively collect harmonized, quantitative, and dimensional psychiatric phenotypes (suicidality, anhedonia, and obsessive‐compulsive symptoms) and information on discrimination, stigma, and unfair treatment in up to 27,500 individuals across diverse ancestries and clinical populations for genetic analysis within the NIMH
