Breeding system of diploid sexuals within the Ranunculus auricomus complex and its role in a geographical parthenogenesis scenario
Kevin Karbstein, Elisabeth Rahmsdorf, Salvatore Tomasello, Ladislav Hodač & Elvira Hörandl
The larger distribution area of asexuals compared to their sexual relatives in geographical parthenogenesis (GP) scenarios has been widely attributed to the advantages of uniparental reproduction and polyploidy. However, potential disadvantages of sexuals due to their breeding system have received little attention so far. Here, we study the breeding system of five narrowly distributed sexual lineages of Ranunculus notabilis s.l. (R. auricomus complex) and its effects on outcrossing, inbreeding, female fitness, and heterozygosity. We performed...

Objective: To determine the nature and extent of minor neuropsychological deficits in patients with subjective cognitive decline (SCD) and their association with cerebrospinal fluid (CSF) biomarkers of Alzheimer’s disease (AD). Method: We analyzed data from n=449 cognitively normal participants (n=209 healthy controls, n=240 SCD patients) from an interim data release of the German Center for Neurodegenerative Diseases Longitudinal Cognitive Impairment and Dementia Study (DELCODE). An extensive neuropsychological test battery was applied at baseline for which...
Subspecies variation of Daucus carota coastal (“gummifer”) morphotypes (Apiaceae) using genotyping-by-sequencing
Fernando Martínez-Flores, Manuel B. Crespo, Philipp W. Simon, Holly Ruess, Kathleen Reitsma, Emmanuel Geoffriau, Charlotte Allender, Najla Mezghani & David M. Spooner
The genus Daucus is widely distributed worldwide, but with a concentration of diversity in the Mediterranean Region. The D. carota complex presents the greatest taxonomic problems in the genus. We focus on a distinctive phenotypic group of coastal morphotypes of D. carota, strictly confined to the margins to within about 0.5 km of the Mediterranean Sea and the Atlantic Ocean, which we here refer to as coastal morphotypes or D. carota subsp. “gummifer” complex, the...
