“…Douhovnikoff et al 2005; Smulders et al 2008), suggesting that increased clonality varies by species or location. Arid and semiarid regions may tend to diverge from the general pattern, since obligate riparian species are generally restricted to stable groundwater supplies (Butterfield et al 2020), potentially resulting in similar cloning rates whether or not surface flows are variable. Alternatively, the dynamism of flash flood driven flows of tributaries in this region may increase clonality.…”

Riparian habitat in the southwestern United States has undergone substantial degradation over the past century, prompting extensive management and restoration of these critical ecosystems. Most restoration efforts, however, do not account for life history traits or riverine complexity that may influence genetic diversity and structure. Here, we use simple sequence repeat markers in four southwestern riparian species (Populus fremontii, Salix gooddingii, S. exigua, and Prosopis glandulosa) that occupy a geographically complex region to address four questions: (1) How is river connectivity related to genetic diversity and structure? (2) How do mating systems and dispersal mechanisms influence gene flow? (3) Is genetic diversity influenced by unidirectional water flow? (4) How do unregulated tributary and regulated river flows affect clonality and associated diversity? Our results identify five findings: (1) Patterns of genetic diversity and structure vary substantially across different species; (2) species with geographic distributions that include a large, perennial river exhibit the least genetic structure; (3) mating system, clonality, and seed dispersal are related to genetic structure; (4) genetic diversity is variable among species and populations, but does not increase or decrease unidirectionally; and (5) clonality and associated diversity does not differ along a regulated river relative to unregulated tributaries. Our multispecies approach to understanding how riverine complexity and life history traits influence genetic diversity and structure could be incorporated into management efforts to more closely match riparian species with their unique environments, thereby facilitating restoration success.

“…Larger Hv is observed in drought-tolerant plants (Canham et al 2009 ) because of higher sapwood area to support leaf area and/or less leaf area supported by such sapwood (Carter and White 2009 ). Higher sapwood area observed in plants at deep sites (Online Resource 12) could enhance Z. lotus capacity for water supply (Butterfield et al 2021 ), and compensate the evaporative demand, particularly in summer. On the one hand, Z. lotus plants with less reliable groundwater supply (deep DTGW) seem to make smaller investments in leaf area than plants at shallow sites (Online Resource 12).…”

A multiple-trait analysis of ecohydrological acclimatisation in a dryland phreatophytic shrub

Water is the main limiting factor for groundwater-dependent ecosystems (GDEs) in drylands. Predicted climate change (precipitation reductions and temperature increases) and anthropogenic activities such as groundwater drawdown jeopardise the functioning of these ecosystems, presenting new challenges for their management. We developed a trait-based analysis to examine the spatiotemporal variability in the ecophysiology of Ziziphus lotus, a long-lived phreatophyte that dominates one of the few terrestrial GDEs of semiarid regions in Europe. We assessed morpho-functional traits and stem water potential along a naturally occurring gradient of depth-to-groundwater (DTGW, 2–25 m) in a coastal aquifer, and throughout the species-growing season. Increasing DTGW and salinity negatively affected photosynthetic and transpiration rates, increasing plant water stress (lower predawn and midday water potential), and positively affected Huber value (sapwood cross-sectional area per leaf area), reducing leaf area and likely, plant hydraulic demand. However, the species showed greater salt-tolerance at shallow depths. Despite groundwater characteristics, higher atmospheric evaporative demand in the study area, which occurred in summer, fostered higher transpiration rates and water stress, and promoted carbon assimilation and water loss more intensively at shallow water tables. This multiple-trait analysis allowed us to identify plant ecophysiological thresholds related to the increase in salinity, but mostly in DTGW (13 m), and in the evaporative demand during the growing season. These findings highlight the existence of tipping points in the functioning of a long-lived phreatophyte in drylands and can contribute to the sustainable management of GDEs in southern Europe, paving the way for further studies on phreatophytic species.

“…While some Salix species, such as S. alba and S. purpurea , are strong components of riparian forests and occur in early‐successional sites, including post‐mining areas with low water levels, others in this genus, such as S. triandra , also colonize these sites. While Salix species usually demonstrate a significant connection between their hydrological and climatic needs, this suggests that these species thrive in favorable environmental conditions, however, may have difficulty adapting to drought or local water level fluctuations (Butterfield et al., 2021 ). Furthermore, these species tend to be more widespread in areas with higher summer rainfall and are often found further away from watercourses (Cavender‐Bares et al., 2004 ).…”

Riparian woody plant communities, including shrubs and trees, are essential for maintaining biodiversity, protecting against floods, reducing erosion, and transporting nutrients. However, these habitats are greatly threatened by human activities, particularly agricultural land acquisition, and the introduction of invasive species. This study examined species diversity and interspecific association in riparian woody plant communities along rivers in the Romanian Carpathians. The study focused on communities of Salix purpurea, S. alba, and Hippophaë rhamnoides in mountain regions, with varying sampling efforts at different sites for each species. A total of 174 plant species were found, predominantly herbaceous (77.9%), followed by trees (11.6%) and shrubs (10.5%). While S. alba and S. purpurea communities show high species richness and abundance, S. alba has slightly higher diversity (H′ ≈ 2.23, SD = 0.28) than S. purpurea (H′ ≈ 1.69, SD = 0.42). Contrarily, significant differences exist between H. rhamnoides and S. alba communities in species richness (p = .007) and Shannon diversity (p = .004). PCA analysis elaborated on distinct distribution patterns of plant associations within habitats S. purpurea community, H. rhamnoides community, and S. alba community. Four invasive species (Oenothera biennis L. and Oxalis stricta L. in S. alba communities, Reynoutria sachalinensis Nakai in both S. purpurea and H. rhamnoides communities, and Erigeron canadensis L. in H. rhamnoides communities) were identified, as requiring conservation efforts. Hemicryptophytes dominate species richness, while microphanerophytes and megaphanerophytes significantly contribute to plant abundance. H. rhamnoides formed Hippophaë rhamnoides dunes (2160) Natura 2000 habitat, while S. alba created galleries within the 92A0 Salix alba and Populus alba habitat. In conclusion, the findings from this study highlight the importance of preserving riparian habitats because their value goes beyond local or regional considerations and extends to the global scale due to their unique characteristics.
