Summary 1. Pollen limitation may be a consequence of changes in pollinator abundance, diversity and identity. However, no empirical evidence exists concerning the consequences that spatial variation fauna has on pollen intensity plant reproduction. In this study, we test effect flower‐visitor identity exert occurrence strength by experimentally quantifying eight populations Erysimum mediohispanicum , pollination‐generalist native to Iberian Peninsula. 2. was accounted for using comprehensive...
An adaptive role of corolla shape has been often asserted without an empirical demonstration how natural selection acts on this trait. In generalist plants, in which flowers are visited by diverse pollinator fauna that commonly vary spatially, detecting pollinator-mediated is even more difficult. study, we explore the mechanisms promoting crucifer Erysimum mediohispanicum Polatschek (Brassicaceae). We found main pollinators E. (large bees, small bees and bee flies) discriminate between...
Supergenes govern multi-trait-balanced polymorphisms in a wide range of systems; however, our understanding their origins and evolution remains incomplete. The reciprocal placement stigmas anthers pin thrum floral morphs distylous species constitutes an iconic example balanced polymorphism governed by supergene, the distyly S-locus. Recent studies have shown that Primula Turnera supergenes are both hemizygous thrums, but it unknown whether hemizygosity is pervasive among S-loci. As has major...
The Geographic Mosaic Theory of Coevolution predicts the occurrence mosaics interaction-mediated local adaptations and maladaptations. Empirical support to this prediction has come mostly from specialist interactions. In contrast, adaptation is considered highly unlikely in generalist study, we experimentally test a plant-pollinator geographic mosaic, by means transplant experiment which plants coming two evolutionary hotspots coldspots were offered pollinators at same four localities....
How generalist plants diverge in response to pollinator selection without becoming specialized is still unknown. This study explores this question, focusing on the evolution of pollination system Erysimum mediohispanicum (Brassicaceae). Pollinator assemblages were surveyed from 2001 2010 48 geo-referenced populations covering entire geographic distribution E. mediohispanicum. Bipartite modularity, a complex network tool, was used find niche each population. Evolution niches and correlated...
Summary It is widely assumed that floral diversification occurs by adaptive shifts between pollination niches. In contrast to specialized flowers, identifying niches of generalist flowers a challenge. Consequently, how evolve largely unknown. We apply tools from network theory and comparative methods investigate the evolution among species belonging genus Erysimum . These have similar flowers. found studied may be grouped in several multidimensional separated not shift pollinators, but...
Floral rewards may be associated with certain morphological floral traits and thus act as underlying factors promoting selection on these traits. This study investigates whether some that are under pollinator-mediated (flower number, stalk height, corolla diameter, tube length width) in the Mediterranean herb E. mediohispanicum (Brassicaceae) (pollen nectar). During 2005 phenotypic visitation rate of main pollinator functional groups were quantified 720 plants belonging to eight populations...
Abstract Distyly is an iconic floral polymorphism governed by a supergene, which promotes efficient pollen transfer and outcrossing through reciprocal differences in the position of sexual organs flowers, often coupled with heteromorphic self-incompatibility. has evolved convergently multiple flowering plant lineages, but also broken down repeatedly, resulting homostylous, self-compatible populations elevated rates self-fertilization. Here, we aimed to study genetic causes genomic...
Flower shape has evolved in most plants as a consequence of pollinator‐mediated selection. Unfortunately, no study explored the genetic variation flower shape, despite that this information is crucial to understand its adaptive evolution. Our main goal here determine heritability corolla Erysimum mediohispanicum (Brassicaceae). Also, we explore other pollinator‐selected traits plant species, such size, display, and size. In addition, investigate correlations between all these traits. We...
Abstract Aim Impacts of different global change drivers are altering the performance plant species worldwide. However, these pressures usually differ across species' distribution range. To properly assess combined effect at level, we need to evaluate its consequences their complete distribution. We focused on recent decline in Cork oak ( Quercus suber L.) populations given high ecological and economic relevance. Location selected 10 sites (and two per site) separated about one degree...
Cryptic species are superficially morphologically indistinguishable and therefore erroneously classified under one single name. The identification delimitation of these is usually a difficult task. main aim this study to provide an inclusive methodology that combines standard new tools allow accurate cryptic species. We used Erysimum nervosum s.l. as model system.Four populations belonging E. were sampled at their two distribution ranges in Morocco (the Atlas Mountains the Rif Mountains)....
Polyploidisation has played an important role in plant diversification, and variation ploidy level may be found not only between species of the same genus, but also within a single species. Although establishing adaptive significance polyploidy to explain geographic distribution cytotypes is challenging, occurrence different ecological niches suggest genome duplication. We studied across entire range endemic Erysimum mediohispanicum (Brassicaceae). For that, we have used climate variables,...
Summary Outbreeding response, the phenotypic differences observed between selfed parental lines and their outcrossed offspring, can influence evolution of selfing strategies. However, such effect remains poorly understood in non-crop species. We investigated outbreeding response variation across ploidy levels Erysimum incanum , a predominantly plant complex with diploid, tetraploid, hexaploid populations distributed Iberian Peninsula Morocco. performed controlled within-population crosses to...
Climate change is threatening species with extinction, and rapid evolutionary adaptation may be their only option for population rescue over short ecological timescales. However, direct observations of genetic dynamics across climates are rare species. To fill this gap, we conducted a replicated, globally synchronized evolution experiment the plant Arabidopsis thaliana 5 years in 30 outdoor experimental gardens distinct Europe, Levant, North America. We performed whole-genome sequencing on...
Individual variation in the magnitude of inbreeding depression (ID) plants and its association with phenotypic traits may have important consequences for mating system evolution. This has been investigated only scarcely, always considering functionally related to autogamy. Here, we explore between individual ID plant associated pollinator attractiveness (related size, corolla size shape) two populations Erysimum mediohispanicum (Brassicaceae). was calculated along entire life cycle plants....
The theory of evolution is one the greatest scientific achievements in intellectual history humankind, yet it still contentious within certain social groups. Despite being as robust and evidence-based any other notable theory, some people show a strong reluctance to accept it. In this study, we used Measure Acceptance Theory Evolution (MATE) Knowledge Exam (KEE) questionnaires with university students from four academic degree programs (Chemistry, English, History, Biology) ten universities...
Hybrid zones have the potential to shed light on evolutionary processes driving adaptation and speciation. Secondary contact hybrid are particularly powerful natural systems for studying interaction between divergent genomes understand mode rate at which reproductive isolation accumulates during We studied a total of 720 plants belonging five populations from two Erysimum (Brassicaceae) species presenting zone in Sierra Nevada mountains (SE Spain). The were phenotyped 2007 2017, most them...

The isolation-by-distance model (IBD) predicts that genetic differentiation among populations increases with geographic distance. Yet, empirical studies show a variety of ecological, topographic and historical factors may override the effect distance on variation. This particularly apply to species narrow but highly heterogeneous distribution ranges, such as those occurring along elevational gradients. Using nine SSR markers, we study montane pollination-generalist herb, Erysimum...
The phylogeny of tribe Brassiceae (Brassicaceae) has not yet been resolved because its complex evolutionary history. This comprises economically relevant species, including the genus Moricandia DC. is currently distributed in North Africa, Middle East, Central Asia and Southern Europe, where it associated with arid semi-arid environments. Although some species have used several phylogenetic studies, this well established.Here we present a analysis using nuclear (the internal transcribed...
Abstract Premise The relationships between reproductive investment, phenotype, and fitness have been broadly studied in cross‐pollinated plants contrast to selfing species, which are considered less interesting this area because they supposed be a dead end any evolutionary pathway. Still, unique systems study these questions since the position of structures traits related flower size play an important role female male pollination success. Methods Erysimum incanum s.l. is species complex that...
