Abstract The identification of native sources and vectors introduced species informs their ecological evolutionary history may guide policies that seek to prevent future introductions. Population genetics provides a powerful set tools identify origins vectors. However, these can mislead when the range is poorly sampled or few molecular markers are used. Here, we traced introduction Asian seaweed Gracilaria vermiculophylla (Rhodophyta) into estuaries in coastal western North America, eastern...
The rapid evolution of non-native species can facilitate invasion success, but recent reviews indicate that such microevolution rarely yields expansion the climatic niche in introduced habitats. However, because some invasions originate from a geographically restricted portion native range and its niche, it is possible frequency, direction, magnitude phenotypic during have been underestimated. We explored utility shift analyses red seaweed
Développement des microsatellites chez l'algue rouge d'eau douce Batrachospermum gelatinosum (L.) De Candolle (Batrachospermales, Rhodophyta). L'étude conséquences éco-évolutionnaires cycles haplo-diplophasiques sur les variations du système de reproduction par le biais la génétique populations nécessite développement marqueurs génétiques adaptés. Cependant, peu polymorphiques nucléaires sont disponibles pour espèces haplo-diploïdes, notamment algues. Dans cette étude, nous décrivons...
Abstract Temporal population genetic studies have investigated evolutionary processes, but few characterized reproductive system variation. Yet, temporal sampling may improve our understanding of evolution through the assessment relative rates selfing, outcrossing, and clonality. In this study, we focused on monoicous, haploid‐diploid freshwater red alga Batrachospermum gelatinosum . This species has a perennial, microscopic diploid phase (chantransia) that produces an ephemeral, macroscopic...
Abstract The relative frequency of sexual versus asexual reproduction governs the distribution genetic diversity within and among populations. Most studies on consequences reproductive variation focus mating system (i.e., selfing vs. outcrossing) diploid‐dominant taxa (e.g., angiosperms), often ignoring reproduction. Although systems are hypothesized to be correlated with life‐cycle types, in rates remains poorly characterized across eukaryotes. This is particularly true three major lineages...
Abstract Life cycles with a prolonged haploid phase are thought to be correlated greater rates of selfing and asexual reproduction. In red algae, recent population genetic studies have aimed test this prediction but mostly focused on marine species separate sexes. We characterized the reproductive system obligately monoicous (i.e., hermaphroditic) freshwater alga Batrachospermum gelatinosum predicted that we would find signatures uniparental reproduction because its haploid‐diploid life...
Abstract The freshwater red alga Batrachospermum gelatinosum has a well‐documented distribution spanning historically glaciated and unglaciated eastern North America. This no known desiccation‐resistant propagule; thus, long‐distance dispersal events are likely rare. We predicted strong genetic structure among drainage basins admixture sites within basins. greater diversity at lower latitude because they serve as refugia the origin of northward, post‐Pleistocene range expansion. used 10...
ABSTRACT The source and vector of an introduced species inform its ecological evolutionary history may guide management that seeks to prevent future introductions. Surprisingly, few studies have successfully used genetic tools independently the specific pathway biological invasions. many species, including their origins vectors, is often based on suppositions or educated guesses. Here, we mitochondrial microsatellite genotyping trace invasion Asian seaweed Gracilaria vermiculophylla...
Temporal population genetic studies have investigated evolutionary processes, but few characterized the temporal patterns of reproductive system variation. Yet, sampling may improve our understanding evolution through assessing relative rates selfing, outcrossing, and clonality.
