Natural genetic variation and negative density effects in plant–nematode interactions
Autor: Maisara Mukhaimar, Marina Pfalz, Jacqui Shykoff, Juergen Kroymann
Publikováno v: Plant-Environment Interactions, Vol 5, Iss 1, Pp n/a-n/a (2024)
Abstract Arabidopsis thaliana is a suitable host for phytoparasitic nematodes of the genus Meloidogyne. Successful nematode infection leads to the formation of root galls. We tested for natural genetic variation and inoculation density effects on nem

Are cuckoos maximizing egg mimicry by selecting host individuals with better matching egg phenotypes?
Autor: Anton Antonov, Bård G Stokke, Frode Fossøy, Peter S Ranke, Wei Liang, Canchao Yang, Arne Moksnes, Jacqui Shykoff, Eivin Røskaft
Publikováno v: PLoS ONE, Vol 7, Iss 2, p e31704 (2012)
BackgroundAvian brood parasites and their hosts are involved in complex offence-defense coevolutionary arms races. The most common pair of reciprocal adaptations in these systems is egg discrimination by hosts and egg mimicry by parasites. As mimicry

Genetic relatedness and eusociality: parasite-mediated selection on the genetic composition of groups
Autor: Paul Schmid-Hempel, Jacqui Shykoff
Publikováno v: Behavioral Ecology and Sociobiology. 28:371-376
Contrary to the expectations of kin selection theory, intracolony relatedness in eusocial insects is often low. We examined the idea that associations of low relatedness (high genetic variability) may be advantageous because of negative frequency-dep

Parasites and the advantage of genetic variability within social insect colonies
Autor: Jacqui Shykoff, Paul Schmid-Hempel
Publikováno v: Proceedings of the Royal Society of London. Series B: Biological Sciences. 243:55-58
Genetic variability within colonies of eusocial insects is often higher than expected if kin selection alone explains sociality. Parasites and pathogens have been proposed as selective agents maintaining genetic variability in populations and promoti

Virulence et infections multiples de Hyaloperonospora arabidopsidis (Gäum.) Göker, Riethm., Voglmayr, Weiss & Oberw. chez Arabidopsis thaliana (L.) Heyhn
Autor: Falab, Shanerin
Publikováno v: Parasitology. Université Paris Saclay (COmUE), 2018. English. ⟨NNT : 2018SACLS246⟩
Multiple infections are common in nature, and are considered very important in the evolution of parasite life-history traits. Theoretically, multiple infections should lead to evolution of higher levels of virulence both as an adaptive and as a plast
