Recoverability of ancestral recombination graph topologies
Theor Popul Biol. 2023 Aug 4:S0040-5809(23)00049-7. doi: 10.1016/j.tpb.2023.07.004. Online ahead of print.ABSTRACTRecombination is a powerful evolutionary process that shapes the genetic diversity observed in the populations of many species. Reconstructing genealogies in the presence of recombination from sequencing data is a very challenging problem, as this relies on mutations having occurred on the correct lineages in order to detect the recombination and resolve the ordering of coalescence events in the local trees. We investigate the probability of reconstructing the true topology of ancestral recombination graphs (AR...

Untangling the role of temporal and spatial variations in persistence of populations
Theor Popul Biol. 2023 Jul 13:S0040-5809(23)00048-5. doi: 10.1016/j.tpb.2023.07.003. Online ahead of print.ABSTRACTWe consider a population distributed between two habitats, in each of which it experiences a growth rate that switches periodically between two values, 1-ɛ>0 or -(1+ɛ)<0. We study the specific case where the growth rate is positive in one habitat and negative in the other one for the first half of the period, and conversely for the second half of the period, that we refer as the (±1) model. In the absence of migration, the population goes to 0 exponentially fast in each environment. In this paper, we ...
