“…Barret and Kohn, 1991;Ellstrand and Elam, 1993;Honnay and Jacquemyn, 2007), the results for M. catharinensis do not support the hypothesized loss of genetic diversity, which should reflect high levels of inbreeding, as a consequence of reduced population size and narrow endemism. Although contradictory to theoretical predictions, unexpectedly high levels of genetic diversity are not unusual for narrow endemics (e.g., Fernández-Mazuecos et al, 2014;Jiménez-Mejías et al, 2015;Turchetto et al, 2016;Forrest et al, 2017;Goetze et al, 2018;Sękiewicz et al, 2020;Bard et al, 2021;Garcia-Jacas et al, 2021), creating an indistinct pattern for this kind of plant species. For instance, in the studies by Fernández-Mazuecos et al (2014) and Jiménez-Mejías et al (2015), the authors highlight the paradox of genetic diversity levels in narrow and extremely narrow endemic plant species from the Mediterranean.…”

“…To this end, and to contribute to in situ and ex situ conservation strategies, we used a high-throughput sequencing approach (i.e., double digest restriction site associated DNA sequencing, ddRADseq; Peterson et al, 2012 ) to identify unlinked and neutral SNP markers. This reduced representation sequencing method had been used extensively for species conservation studies (e.g., Nazareno et al, 2017 ; Chattopadhyay et al, 2019 ; Amor et al, 2020 ; Wright et al, 2020 ; Bard et al, 2021 ; Nazareno and Knowles, 2021 ) mainly due to its robustness to generate thousands of neutral and non-neutral molecular markers at a relative low cost. Our population genomic study tackles a central issue in evolution and conservation biology and we expect that it will be useful to safeguard the genetic diversity reported for the only remaining population of M. catharinensis .…”

“…Reduced populations with low allelic diversity are at greater threat of genostasis, or delimited evolution resulting from decreased genotypic and phenotypic plasticity ) 19 . This can inhibit stress responses from specialized taxa in changing climates and increases their risk of extinction (Bard 2021) 5 . In evaluating Suisun thistle for genetic structure, also referred to as population structure, we determined the presence or absence of a non-random difference in allele frequencies between subpopulations.…”

“…The consistent Mediterranean climate patterns of the CA-FP are marked by seasonal variation with cool wet winters and warm dry summers and by longitudinal gradients spanning from the arid deserts of Southern California through the cooler cascade mountains in the north (Baldwin 2014) 4 . The various environmental microclimates and stressors within the province are thought to rapidly drive adaptive radiation, a process of diversification and selection through which neoendemic species may arise with developed habitat use niches (Bard 2021) 5 . This array of distinct habitats within a relatively stable macroclimate contributes to high rates of endemic plant species in the CA-FP, where 40% of over 5500 native plant species are endemic (Stebbins and Major 1965, Lancaster and Kay 2013) 6,7 .…”
