“…The central Japanese mountains are the highest in the archipelago (~3,000 m), allowing for altitudinal range shifts in response to climatic oscillations and enabling long-term population persistence. Similar north-south differentiation has also been found in other cool-climate species in Japan, including sub-alpine herbs (Kikuchi et al 2013), a low-altitude herb (Lihová et al 2010), trees (Aizawa et al 2007;Tsuda and Ide 2005), and leaf beetles (Sota and Hayashi 2007). In contrast, we found no such geographic differentiation in V. vitis-idaea (Table 2), in which most haplotypes were widespread throughout Japan (Fig.…”

Arctic-alpine plants have expanded and contracted their ranges in response to the Pleistocene climate oscillations. Today, many arctic-alpine plants have vast distributions in the circumarctic region as well as marginal, isolated occurrences in high mountains at lower latitudes. These marginal populations may represent relict, long-standing populations that have persisted for several cycles of cold and warm climate during the Pleistocene, or recent occurrences that either result from southward step-wise migration during the last glacial period or from recent long-distance dispersal. In light of these hypotheses, we investigated the biogeographic history of the marginal Japanese populations of the widespread arctic-alpine plant Vaccinium vitis-idaea (Ericaceae), which is bird-dispersed, potentially over long distances. We sequenced three nuclear loci and one plastid DNA region in 130 individuals from 65 localities covering its entire geographic range, with a focus on its marginal populations in Japan. We found a homogenous genetic pattern across its enormous range based on the loci analysed, in contrast to the geographically structured variation found in a previous study of amplified fragment length polymorphisms in this species. However, we found several unique haplotypes in the Japanese populations, excluding the possibility that these marginal populations result from recent southward migration. Thus, even though V. vitis-idaea is efficiently dispersed via berries, our study suggests that its isolated populations in Japan have persisted during several cycles of cold and warm climate during the Pleistocene.

“…Because alternative approaches to analyzing AFLP data may lead to different conclusions (Burnier et al 2009;Lihová et al 2010;Espíndola and Á lvarez 2011), to identify the most likely number of distinct genetic groups present in our data set we decided to apply three different methods based on distinct model assumptions and methodologies (Gao et al 2007;Jombart et al 2009). By explicitly adopting this combined approach, it will be possible to evaluate the robustness of conclusions to different analytical methods.…”

“…First, the number of loci used may have been high, enabling detection of a great part of the variation within each population (Sunnucks, 2000). This seems to be a common result when AFLP markers are used to measure genetic variation in plants (Lihová, Kudoh, & Marhold, 2010;Nybom, 2004;Steinger, Haldimann, Leiss, & Müller-Schärer, 2002) in contrast to findings using isozyme markers. This is a clear pattern in Cactaceae (Cornejo-Romero, Vargas-Mendoza, Valverde, & Rendón-Aguilar, 2013) and Agavaceae (Eguiarte et al, 2013) or in other ruderal plants with the same reproductive system as R. nudiflora (Culley, & Wolfe 2001;Imaizumi, Wang, & Tominaga, 2008).…”

Revista Mexicana de Biodiversidad 86 (2015) 508-520 Evolution Genetic diversity, outcrossing rate, and demographic history along a climatic gradient in the ruderal plant Ruellia nudiflora (Acanthaceae)Diversidad genética, tasa de entrecruzamiento e historia demográfica a lo largo de un gradiente climático en la planta ruderal Ruellia nudiflora (Acanthaceae) AbstractRuellia nudiflora has shown a high potential to easily invade disturbed areas. Outcrossing rate and genetic structure and diversity in this species were examined along a climatic gradient in the Yucatán Peninsula (Mexico) in order to understand the effects of environmental heterogeneityisolation by environment (IBE) -as well as correlation in herkogamy on genetic structure, diversity, and demographic history in this species. Nine populations were sampled along a temperature-precipitation gradient with marked differences in vegetation, measuring the degree of herkogamy in each sampled plant. To evaluate genetic diversity and structure, amplified fragment length polymorphism (AFLP) markers from 76 plants in these populations were used, while the outcrossing rate was evaluated in 22 genetic families from six populations. All populations had high levels of within-population genetic diversity and high outcrossing rates. Virtually all populations were also undergoing demographic and spatial expansion. The partial Mantel test found a positive correlation between geographic and genetic distance, but none between mean temperature, precipitation, and herkogamy with genetic distance. In this context, R. nudiflora shows incipient evidence of genetic differentiation on a small geographical scale (isolation by distance, IBD) but not along the environmental gradient (IBE). Results suggest that under conditions of constant disturbance, R. nudiflora is able to continuously colonize new areas.

Con la finalidad de comprender los efectos de la heterogeneidad ambiental (aislamiento por el ambiente, IBE) y de la correlación en la hercogamia, sobre la diversidad, estructura genética e historia demográfica de esta especie, se examinaron la tasa de entrecruzamiento, la estructura y diversidad genética a lo largo de un gradiente climático en la península de Yucatán (México). Se muestreó un total de 9 poblaciones a lo largo de un gradiente de temperatura-precipitación con marcadas diferencias en la vegetación, en donde además se midió el grado de hercogamia en cada planta. Para evaluar la diversidad y estructura genética, se usaron AFLP's en 76 plantas de estas poblaciones, mientras que la tasa de entrecruzamiento se evaluó en 22 familias genéticas de * Corresponding author.
