Dynamics of mtDNA introgression during species range expansion: insights from an experimental longitudinal study
Introgressive hybridization represents one of the long-lasting debated genetic consequences of species range expansion. Mitochondrial DNA has been shown to heavily introgress between interbreeding animal species that meet in new sympatric areas and, often, asymmetric introgression from local to the colonizing populations has been observed. Disentangling among the evolutionary and ecological pro...
متن کاملInvestigating Effects of a Prescribed Spring Fire on Symbiosis between Mycorrhiza Fungi and Range Plant Species
Fire is one of the incorporate vegetation management practices for grasslands and semi-arid rangelands. It may affect symbiotic relationship between range plants and mycorrhiza. Accordingly, this research was aimed to investigate the effects of a spring prescribed fire on the symbiotic relationships between mycorrhiza and 6 plant species. The study was conducted in a semi-arid steppe rangeland ...
متن کاملSpatial analysis improves species distribution modelling during range expansion.
Species distribution models (SDMs) assume equilibrium between species' distribution and the environment. However, this assumption can be violated under restricted dispersal and spatially autocorrelated environmental conditions. Here we used a model to simulate species' ranges expansion under two non-equilibrium scenarios, evaluating the performance of SDM coupled with spatial eigenvector mappin...
متن کاملReduced inbreeding depression after species range expansion.
Many species expanded their geographic ranges from core "refugium" populations when the global climate warmed after the Pleistocene. The bottlenecks that occur during such range expansions diminish genetic variation in marginal populations, rendering them less responsive to selection. Here, we show that range expansion also strongly depletes inbreeding depression. We compared inbreeding depress...
متن کاملTitle: Species Range Expansion Constrains the Ecological Niches of Running Header: Range Expansion and Changes in Species Interactions
21 Aim Changes in community composition resulting from environmental changes modify biotic 22 interactions and affect the distribution and density of local populations. Such changes are currently 23 occurring in nettle-feeding butterflies in Sweden where Araschnia levana has recently expanded 24 its range northward and is now likely to interact with the resident species (Aglais urticae and Agla...
