Decreased coevolutionary potential and increased symbiont fecundity during the biological invasion of a legume-rhizobium mutualism
<p>Although most invasive species engage in mutualism, we know little about how mutualism evolves as partners colonize novel environments. Selection on cooperation and standing genetic variation for mutualism traits may differ between a mutualism's invaded and native ranges, which could alter cooperation and coevolutionary dynamics. To test for such differences, we compare mutualism traits between invaded- and native-range host-symbiont genotype combinations of the weedy legume, <i>Medicago polymorpha,</i> and its nitrogen-fixing rhizobium symbiont, <i>Ensifer medicae</i>, which have co-invaded North America. We find that mutualism benefits for plants are indistinguishable between invaded- and native-range symbioses. However, rhizobia gain greater fitness from invaded-range mutualisms than from native-range mutualisms, and this enhancement of symbiont fecundity could increase the mutualism's spread by increasing symbiont availability during plant colonization. Furthermore, mutualism traits in invaded-range symbioses show lower genetic variance and a simpler partitioning of genetic variance between host and symbiont sources, compared to native-range symbioses. This suggests that biological invasion has reduced mutualists' potential to respond to coevolutionary selection. Additionally, rhizobia bearing a locus (<i>hrrP</i>) that can enhance symbiotic fitness have more exploitative phenotypes in invaded-range than in native-range symbioses. These findings highlight the impacts of biological invasion on the evolution of mutualistic interactions.</p>
Data from: High invasion potential of Hydrilla verticillata in the Americas predicted using ecological niche modeling combined with genetic data
Ecological niche modeling is an effective tool to characterize the spatial distribution of suitable areas for species, and it is especially useful for predicting the potential distribution of invasive species. The widespread submerged plant Hydrilla verticillata (hydrilla) has an obvious phylogeographical pattern: Four genetic lineages occupy distinct regions in native range, and only one lineage invades the Americas. Here, we aimed to evaluate climatic niche conservatism of hydrilla in North America at the intraspecific level and explore its invasion potential in the Americas by comparing climatic niches in a phylogenetic context. Niche shift was found in the invasion process of hydrilla in North America, which is probably mainly attributed to high levels of somatic mutation. Dramatic changes in range expansion in the Americas were predicted in the situation of all four genetic lineages invading the Americas or future climatic changes, especially in South America; this suggests that there is a high invasion potential of hydrilla in the Americas. Our findings provide useful information for the management of hydrilla in the Americas and give an example of exploring intraspecific climatic niche to better understand species invasion.
Data from: Spartina alterniflora invasion drastically increases methane production potential by shifting methanogenesis from hydrogenotrophic to methylotrophic pathway in a coastal marsh
1. Plant invasion can strongly influence carbon (C) cycling processes, thus it may affect climate change by altering C sequestration and greenhouse gas emissions in the invaded ecosystem. Since 1979, the exotic Spartina alterniflora has rapidly expanded in China's coastal areas, where significant increase in methane (CH4) emissions has been documented from post-invaded sites. However, a mechanistic understanding of the structural and functional changes of associated methanogens accompanying this invasion remains elusive. 2. Here we conducted integrated biogeochemical investigations on methanogenic substrates, activity, and diversity to identify implications of S. alterniflora invasion for methanogenesis in coastal wetlands. To do this, we collected and analyzed 0–50 cm soil profiles from an uncolonized tidal flat (TF) and salt marshes that S. alterniflora has invaded for 1 year (SA-1) and 12 years (SA-12) in Jiangsu, China. Methanogenic community composition was characterized by massive parallel sequencing. The rates and pathways of methanogenesis were determined by adding trace concentrations of 13C-labeled substrates to anaerobic incubated samples. 3. Our results revealed that 12-year invasion of S. alterniflora drastically increased CH4 production potential by one order of magnitude over that of TF. This substantial increase was primarily attributed to methanogenesis from trimethylamine; its rates increased by two orders of magnitude over TF whereas those from acetate and H2/CO2 increased far less. Hydrogenotrophic methanogenesis was the dominant pathway operating in the TF, but methanotrophic pathway contributed most to CH4 production in the surface layer of SA-1 and upper-most 40-cm layers of SA-12. Consistent with these observations, the dominant methanogens shifted from obligate hydrogenotrophic Methanococcales in TF to potential methylamine-utilizing Methanosarcinaceae in SA-12. Our Mantel analysis indicated that 'non-competitive' trimethylamine, derived from cytoplasmic osmolytes of S. alterniflora, was the major driver of this change in methanogenic community composition. 4. Synthesis. Our results suggest that invasive S. alterniflora plants gradually facilitated the local dominance of methylotrophic Methanosarcinaceae by changing the key type of methanogenic substrate in coastal marshes. Shifts in methanogen communities and enhanced availability of trimethylamine elevated the rates and importance of methylotrophic methanogenesis, thereby markedly increasing CH4 production potential and emission rates in this type of ecosystem.
Data from: Tracking the origins of fly invasions; using mitochondrial haplotype diversity to identify potential source populations in two genetically intertwined fruit fly species (Bactrocera carambolae and Bactrocera dorsalis [Diptera: Tephritidae])
Bactrocera carambolae Drew and Hancock and B. dorsalis (Hendel) (Diptera: Tephritidae) are important pests of many fruits. These flies have been spread across the world through global travel and trade, and new areas are are at risk of invasion. Whenever new invasive populations are discovered, quick and accurate identification is needed to mitigate the damage they can cause. Determining invasive pathways can prevent further spread of pests as well as subsequent reinvasions through the same pathway. Molecular markers can be used for both species identification and pathway analysis. We analyzed 1601 individuals from 18 populations using 765 base pairs of the mitochondrial cytochrome oxidase I (COI) gene to infer the haplotype diversity and population structure within these flies from across their native and invasive ranges. We analyzed these samples by either grouping by species or geographic populations due to the genetic similarity in the mitochondrial genome. We found no genetic structure between B. dorsalis and B. carambolae and our findings suggest recent and most likely ongoing, genetic exchange between these two species in the wild. Hyper-diverse mitochondrial genetic diversity in the native range suggests large population sizes and relatively high mutation rates. Only 52% of the haplotypes found in the trap captures from California are shared with haplotypes from flies found in our global survey, indicating significant genetic diversity in the native range that is missing from our samples. However, these results provide a foundation for the accurate determination of the provenance of invasive populations around the world.
The genetic drivers for the successful invasive potential of a generalist bird, the House crow
<p>What kind of genetic structure helps the rapid range expansion of the invasive species is fundamental to understand spread of invasion. The House crow (<i>Corvus splendens</i>), an ecological generalist, having a large native and introduced distribution range, is a good study model to investigate the genetic structure and adaptations underpinning the evolutionary potential for successful biological invasion. Thirteen mainland and one island native population from the Indian subcontinent were studied using four nuclear introns and mitochondrial genome to determine the phylogeographic structure and demographic history. A large, panmictic long-term expanding native population dating from the last glacial period (~30,000 ya) was inferred leading to great genetic diversity across the whole native range. The thirteen mitochondrial encoded proteins, directly involved in the energy supplying pathway, could underlie metabolic adaptations during range expansion under diverse climate conditions. Therefore, to investigate the molecular selection on these genes in native and introduced ranges, five previously studied introduced populations from Southeast Asia and Africa were included. The native populations originating from hot arid and humid tropical areas exhibited the signatures of positive selection on four codons located in three genes (ND5, Cytb and COX2), suggesting these may have evolved under environmental stresses in those regions. Our findings demonstrated the native range population as the reservoir of the species' genetic diversity, mitogenomic patterns of the introduced populations related to native range of species and no variants could be associated with climate in introduced range. Thus, inferred that the pre-adapted standing genetic variations evolved during dispersion over the native range are the predominant source of the high evolutionary potential and contribute to the successful invasion history. These findings will help to predict the future introduced range of the House crow.</p>
