J Evol Biol
. 2025 Mar;
PMID: 40036782
The study of mating systems, defined as the distribution of who mates with whom and how often in a sexually reproducing population, forms a core pillar of evolution research due...

Mol Biol Evol
. 2024 Jun;
41(7).
PMID: 38935572
Two important characteristics of metapopulations are extinction-(re)colonization dynamics and gene flow between subpopulations. These processes can cause strong shifts in genome-wide allele frequencies that are generally not observed in "classical"...

Evolution
. 2023 Jun;
77(9):1987-1999.
PMID: 37345677
Obligate parthenogenesis (OP) is often thought to evolve by disruption of reductional meiosis and suppression of crossover recombination. In the crustacean Daphnia pulex, OP lineages, which have evolved from cyclical...

Evolution
. 2023 Jan;
77(1):1-12.
PMID: 36622707
In some asexual species, parthenogenetic females occasionally produce males, which may strongly affect the evolution and maintenance of asexuality if they cross with related sexuals and transmit genes causing asexuality...

Mol Biol Evol
. 2022 Dec;
39(12).
PMID: 36472514
The dynamics of extinction and (re)colonization in habitat patches are characterizing features of dynamic metapopulations, causing them to evolve differently than large, stable populations. The propagule model, which assumes genetic...

J Evol Biol
. 2021 Sep;
34(11):1817-1826.
PMID: 34592015
The intensity of mating competition and the opportunity for sexual selection are thought to depend on the operational sex ratio, the ratio of sexually active males to fertilizable females. Cyclic...

Boyer L, Jabbour-Zahab R, Mosna M, Haag C, Lenormand T
Evol Lett
. 2021 Apr;
5(2):164-174.
PMID: 33868712
The maintenance of sex is paradoxical as sexual species pay the "twofold cost of males" and should thus quickly be replaced by asexual mutants reproducing clonally. However, asexuals may not...

Lohr J, Haag C
Ecology
. 2020 May;
101(10):e03105.
PMID: 32452541
Asexual species are thought to suffer more from coevolving parasites than related sexuals. Yet a variety of studies do not find the patterns predicted by theory. Here, to shine light...

PMID: 31320584
normally reproduce by cyclical parthenogenesis, with offspring sex being determined by environmental cues. However, some females have lost the ability to produce males. Our results demonstrate that this loss of...
