Sweepstakes reproduction facilitates rapid adaptation in highly fecund populations

B Eldon, W Stephan - Molecular Ecology, 2024 - Wiley Online Library
Adaptation enables natural populations to survive in a changing environment.
Understanding the mechanics of adaptation is therefore crucial for learning about the …

Simultaneous inference of past demography and selection from the ancestral recombination graph under the beta coalescent

K Korfmann, TPP Sellinger, F Freund… - Peer Community …, 2024 - peercommunityjournal.org
The reproductive mechanism of a species is a key driver of genome evolution. The standard
Wright-Fisher model for the reproduction of individuals in a population assumes that each …

Determinants of rapid adaptation in species with large variance in offspring production

K Korfmann, M Temple‐Boyer, T Sellinger… - Molecular …, 2024 - Wiley Online Library
The speed of population adaptation to changing biotic and abiotic environments is
determined by the interaction between genetic drift, positive selection and linkage effects …

Bursts of coalescence within population pedigrees whenever big families occur

D Diamantidis, WT Fan, M Birkner, J Wakeley - Genetics, 2024 - academic.oup.com
We consider a simple diploid population-genetic model with potentially high variability of

Reproductive resilience or sweepstakes recruitment? Assessing drivers of lifetime reproductive success in exploited marine fish

MD Tringali, SK Lowerre‐Barbieri - Fish and Fisheries, 2023 - Wiley Online Library
Understanding the processes that drive reproductive success in marine fish stocks is critical
to effective fisheries management. These processes can be difficult to investigate, especially …

[HTML][HTML] The ancestral selection graph for a Λ-asymmetric Moran model

AG Casanova, N Kurt, JL Pérez - Theoretical population biology, 2024 - Elsevier
Motivated by the question of the impact of selective advantage in populations with skewed
reproduction mechanisms, we study a Moran model with selection. We assume that there …

Inference of multiple mergers while dating a pathogen phylogeny

D Helekal, J Koskela, X Didelot - Systematic Biology, 2025 - academic.oup.com
The vast majority of pathogen phylogenetic studies do not consider the possibility of multiple
merger events being present, where a single node of the tree leads to more than two …
