“…The high values of coefficient of variation found in diverse edaphic variables, evidence soil properties that still keep great dynamics, which is characteristic for not consolidated soils in embryo dunes ( van Puijenbroek et al, 2021 ). In such edaphic conditions, the establishment of vegetation occurs with pioneer species or with species with a certain level of rusticity or adaptation to poor soils, which limits the number of species present ( Ripley & Pammenter, 2008 ; Šile et al, 2017 ).…”

“…Plant species exclusive of embryo dunes play a key role in stabilizing the dune, and the accumulation of finer particles such as fine and very fine sand, silts, organic matter, and salt, which are carried by the wind processes, which constitute the most important source of nutrients for the plant and enrichment of organic matter in the dunes ( Yu, Rhew & Kim, 2004 ). As this process of sedimentation of fine particles occurs, suitable conditions are generated for the ubiquitous species to arrive ( Pan, Zhang & Li, 2016 ; Wang et al, 2019 ; van Puijenbroek et al, 2021 ).…”

“…The complex interrelations between geomorphology, soil, and vegetation are key factors in the formation of ecological patterns and processes ( Landi, Ricceri & Angiolini, 2012 ). This complexity can be understood as a chain of causal connections between geomorphological phenomena, soil conditions, and vegetation patterns ( Moreno-Casasola, 1982 ; Kim & Yu, 2009 ; van Puijenbroek et al, 2021 ). The embryo dunes of the coast of Jalisco, México, show a complex interaction between plants and ambient, which is validated by the relatively low but significant explanation of the variance with the CCA and the moderately low but significant correlation between environmental grouping and plant species grouping.…”

“…Commonly, embryo dunes are populated by pioneer vegetation species that can cope with sand burial ( Gómez et al, 2017 ). Initially, embryonic dunes may increase species richness, but later they may compete for space, further reducing species richness ( van Puijenbroek et al, 2021 ).…”

Background The poorly developed soils of the embryo dunes imply little capacity for plant support, however, the adaptation mechanisms of plants respond sensitively to environmental variations, even when these variations are small, which results in a set of specialized habitats and flora that are rarely shared with other terrestrial ecosystems. The coastal dunes of the Mexican Pacific remain vaguely studied, this is why this research explored the relationship between environmental properties and the presence of plant species in the embryo dunes of the coast of Jalisco, Mexico. Methods Twenty-nine sites were sampled, one or two sites per embryo dune, with a random stratified design. Geomorphological and vegetation data were collected at site. Laboratory determinations included soil color, particle size, organic matter, pH, electrical conductivity, magnetite content, and moisture retention. Statistical analysis included correlation analysis to identify relationships between environmental variables; principal component analysis (PCA) and cluster analysis to group dune sites by environmental properties; canonical correspondence analysis (CCA) to determine a possible significant relationship between the presence of plant species and environmental variables; cluster analysis to group dune sites by presence/absence of plant species and correlate both clusters to validate the relationship between them, the salient aspects of this relationship were described and the spatial distribution of the groups was mapped. Results Eleven plant species were identified, six of them exclusive to the embryo dunes and the rest ubiquitous. The incipient development of these soils is reflected in a low content of organic matter, silt, clay, and moisture retention, with scattered data on granulometry, electrical conductivity, organic matter, and magnetite. Some significant correlations were found between some environmental properties, and the CCA showed a significant relationship between the presence of plant species and environmental variables (p-value of the Monte Carlo test = 0.026). The cluster analysis of dune sites according to environmental variables and the cluster analysis by presence/absence of plant species produces the formation of five groups of sites with significant environmental differences and five groups of sites with significant floristic differences. A significant connection (r = 0.471, p = 0.01) between the two clustering schemes also evidences the meaningful relationship between the presence of plant species and the environmental characteristics of the embryo dunes of Jalisco, Mexico. Differences in habitat preferences were observed among plant species exclusive to the embryo dunes; thus, Abronia maritima, Uniola pittieri, and Pectis arenaria showed a preference for embryo dunes with poor edaphic conditions, in contrast to Okenia hypogaea, Canavalia rosea, and Scaevola plumieri, which were mostly found in embryo dunes with higher fertility.
