“…Such findings indicate that sexual reproduction is naturally quite common. In addition, little genetic differentiation among populations has been found for many wetland species, which is an indicator of high gene flow among wetlands via seeds (Santamaría, 2002;Pollux et al, 2009;Nilsson et al, 2010;Sweetman et al, 2013;Ngeve et al, 2017;Orsenigo et al, 2017;Kettenring et al, 2019b;Lobato de Magalhães et al, 2020).…”

As we approach the Decade of Ecosystem Restoration (2021-2030), there is renewed focus on improving wetland restoration practices to reestablish the habitat and climate mitigation functions and services that wetlands provide. A first step in restoring these functions and services is to reestablish the native vegetation structure and composition through strategic seed-based approaches. These approaches should be driven by ecological, genetic, and evolutionary principles, along with consideration for economics, logistics, and other social constraints. Effective seed-based approaches must consider the chosen species, seed sourcing, dormancy break and germination requirements, seed enhancement technologies, potential invaders, seeding densities, and long-term monitoring. Choice of species should reflect historical plant communities and future environmental conditions, species that support functional goals including invasion resistance, and seed availability constraints. Furthermore, seeds should be sourced to ensure ample genetic diversity to support multifunctionality and evolutionary capacity while also considering the broad natural dispersal of many wetland species. The decision to collect wild seeds or purchase seeds will also impact species choice and genetic diversity, which can have cascading effects for functional goals. To ensure seedling establishment, seed dormancy should be addressed through dormancy breaking treatments and the potentially narrow germination requirements of some species will require targeted sowing timing and location to align with safe sites. Other seed enhancements such as priming and coatings are poorly developed for wetland restoration and their potential for improving establishment is unknown. Because wetlands are highly invasion prone, potential invaders and their legacies should be addressed. Seeding densities should strike a balance between outcompeting invaders and preserving valuable seed resources. Invader control and long-term monitoring is key to improving revegetation and restoration. Here, we review scientific advances to improve revegetation outcomes, and provide methods and recommendations to help achieve the desired goals. Gaps in knowledge about seed-based wetland restoration currently exist, however, and untested practices will certainly increase risks in future efforts. These efforts can be used to better understand the ecological, genetic, and evolutionary processes related to wetland seeds, which will bring us one step closer to seed-based restoration of functions and services needed for human and ecological communities.

“…In recent years, numerous lines of evidence have indicated that some other landscape components can influence gene flow and population connectivity independent of geographical distance. These components include bioclimatic variables (elevation, humidity, and precipitation; Bontrager & Angert, 2019; Gharehaghaji et al., 2017), discrete variables (habitat or substrate type; Hopley & Byrne, 2018; Roffler et al., 2016), abiotic factors (heat, drought, and salt; Quiñones‐Pérez et al., 2014)), or biotic factors (vegetation density and diversity; Lobato‐de Magalhaes et al., 2020). For R. trigyna , the geographical characteristics among the subpopulations vary in latitude, longitude, altitude, and climate conditions, leading to the heterogeneity of habitats; thus, they might contribute to the identified patterns of population differentiation (Bontrager & Angert, 2019; Duan et al., 2018; Gharehaghaji et al., 2017; Lobato‐de Magalhaes et al., 2020; Roffler et al., 2016; Y.

Genetic diversity reflects the survival potential, history, and population dynamics of an organism. It underlies the adaptive potential of populations and their response to environmental change. Reaumuria trigyna is an endemic species in the Eastern Alxa and West Ordos desert regions in China. The species has been considered a good candidate to explore the unique survival strategies of plants that inhabit this area. In this study, we performed population genomic analyses based on restriction‐site associated DNA sequencing to understand the genetic diversity, population genetic structure, and differentiation of the species. Analyses of 92,719 high‐quality single‐nucleotide polymorphisms (SNPs) indicated that overall genetic diversity of R. trigyna was low (HO = 0.249 and HE = 0.208). No significant genetic differentiation was observed among the investigated populations. However, a subtle population genetic structure was detected. We suggest that this might be explained by adaptive diversification reinforced by the geographical isolation of populations. Overall, 3513 outlier SNPs were located in 243 gene‐coding sequences in the R. trigyna transcriptome. Potential sites under diversifying selection occurred in genes (e.g., AP2/EREBP, E3 ubiquitin‐protein ligase, FLS, and 4CL) related to phytohormone regulation and synthesis of secondary metabolites which have roles in adaptation of species. Our genetic analyses provide scientific criteria for evaluating the evolutionary capacity of R. trigyna and the discovery of unique adaptions. Our findings extend knowledge of refugia, environmental adaption, and evolution of germplasm resources that survive in the Ordos area.

“…However, even if we underestimated pond connectivity, the effect of the simple geographic distance emerged with relatively large effect size, suggesting a strong directionality of biotic connections in selected social behaviour types governed by the presence of the river. More complex connectivity measures could provide a refined understanding of the functional role of individual ponds in the landscape (Lobato‐de Magalhães et al, 2020; Oborny et al, 2007).…”
