“…The shape features captured in the first few PCs in our analysis (Fig. ) resemble those of the corresponding PCs in the same data (Gómez et al ., ), for other data sets for this species (Gómez et al ., , ) and even for data from other species of Erysimum (Ortigosa & Gómez, ; our unpublished analyses of the data of Abdelaziz et al ., ). The resemblance of shape features among corresponding PCs is particularly close for the analyses with the largest sample sizes (Gómez et al ., ; Fig.…”

SummarySymmetry is an important feature of floral structure, and floral symmetries are diverse and often complex. We use a new morphometric approach for analysing shapes with complex types of symmetry, which partitions shape variation into a component of symmetric variation and different components of asymmetry. This approach, based on the mathematical theory of symmetry groups, can be used for landmark configurations with any type of symmetry and is therefore promising as a general framework for morphometric analyses of floral symmetry and asymmetry.We demonstrate this approach by quantifying floral shape variation in a wild population of Erysimum mediohispanicum (Brassicaceae). Flowers of this species are disymmetric, so that the symmetry in the left-right and adaxial-abaxial directions can be considered separately and in combination.Both principal component analysis and Procrustes ANOVA indicate that symmetric variation accounts for most of the total variance and that adaxial-abaxial asymmetry is the dominant component of fluctuating asymmetry. Each component is associated with specific patterns of shape variation.These results illustrate the potential of the new method and suggest new areas for future research. The new morphometric approach is promising for further analyses of floral symmetry and asymmetry in evolutionary and developmental contexts.

“…We have previously shown that corolla shape is under pollinator‐mediated selection, playing an important role in the adaptation to their pollinators of some Erysimum species from the Iberian Peninsula (Gómez et al, 2006, 2008a, 2008b, 2009). Because the selective pressures exerted by pollinators seem to be similar across many Erysimum species (Gómez et al, 2006, 2008a, 2008b, 2009; Gómez and Perfectti, 2010; Ortigosa and Gómez, 2010), these complex traits will presumably also be similar among different species. Consequently, the study of these traits may help to disentangle the evolutionary divergence resulting in morphological differences between closely related species.…”

The joint use of the results obtained from standard taxonomic traits, quantitative analyses of plant phenotype, and molecular data suggests the occurrence of two species within E. nervosum s.l. in Morocco, one located in the Atlas Mountains (E. nervosum s.s.) and the other in the Rif Mountains (E. riphaeanum sp. nov.). Consequently, we suggest that combining quantitative and molecular approaches with standard taxonomy greatly benefits the identification of cryptic species.

“…The components of floral traits, such as plant size, plant age, floral structures and sexual organs arrangement (Arroyo et al 2006;Herlihy and Eckert 2007;Etcheverry et al 2008;Ortigosa and Gomez 2009;Barrett 2011;Tamla et al 2012;da Cruz et al 2014), altogether arrange floral display within population. Differences on floral display might be resulted in different pollinators and pollination behavior, which affect mating systems and genetic diversity (Herlihy and Eckert 2007;Arroyo et al 2006;Barrett 2011;Kartikawati et al 2013), reproductive outputs (Tsaliki and Diekmann 2011;Nadia and Machado 2014) and population fitness (Provan et al 2008;Weber and Kolb 2013).…”

Population structures and seasons affected flowering, pollination and reproductive outputs of sandalwood in Gunung Sewu, Java, Indonesia

Ratnaningrum YWN, Indrioko S, Faridah E, Syahbudin A. 2018. Population structures and seasons affected flowering, pollination and reproductive outputs of sandalwood in Gunung Sewu, Java, Indonesia. Nusantara Bioscience 10: 12-26. Sandalwood was the origin to the south-eastern islands of Indonesia, but is recently occurred as new landraces in Gunung Sewu Geopark, Java, Indonesia. This study compared flowering and pollination, and their effect on reproductive outputs, among sandalwood populations in Gunung Sewu, during the dry and rainy season of 2016 flowering period. Flowering and pollination rate differed significantly between seasons but were similar among sites. Oppositely, reproductive outputs differed significantly among sites, but were similar between seasons. The rainy season produced more flowers and pollination. Pollination was less correlated to flowers abundance, but more affected by population size. The higher and cooler population visited more by Dipterans (31.8% to 32.6%) and Hymenopterans (28.2% to 30%), while the warmer, lower sites dominated by Lepidopterans (37.2% to 43%) and Dipterans (32.9% to 38.2%). Higher population received fewer visits, but more visitors diversity (28 families). In contrast, lower sites received more visits, but with less diversity (20 families). Most insect families were considered â€œRareâ€ and â€œOccasionalâ€. However, pooled altogether, the whole families of Lepidopterans and Dipterans considered â€œFrequentâ€ and â€œEffectiveâ€. The Hymenopterans considered â€œFrequentâ€ and â€œEffectiveâ€ at Nglanggeran and Wanagama. The Cicadellidae of Coleopterans, along with arachnids and grasshoppers, were considered robbers. All of the agents were diurnal. However, the time of activity was varied. Rainy season gained more flowers and visits, but in contrast, resulted in fewer fruits at all sites. Both flowers abundance and pollination were negatively correlated to the reproductive parameters. Populations might gain more flowers and visits, but the reproductive outputs were significantly lower. Particularly in the clonalized and lower heterozygosity populations, more flowers increased geitonogamy which may lead to inbreeding depression.
