Summary Direct physical confrontation among conspecifics for access to mates is a form of sexual selection well known animals, but not thought take place in plants. Consequently, no structures are that can be considered as weapons evolved under such confrontation. Pollinaria milkweeds may physically compete attachment points on the pollinators' body, and occasionally pollinaria link onto pre‐existing pollinator resulting concatenation. We hypothesized concatenation result interference...
Evolution of cross-pollination efficiency depends on the genetic variation flower traits, pollen vector, and trait matching between donors recipients. Trait has been almost unexplored among nonheterostylous species, we examined whether match anther length in stigma recipients influences cross-pollination. To explore potential constraints for evolutionary response, also quantified covariation sepal length, petal width, stamen style herkogamy.
Abstract Pollinator‐mediated natural selection on single traits, such as corolla tube or spur length, has been well documented. However, flower phenotypes are usually complex, and is expected to act several traits that functionally interact rather than a isolated trait. Despite the fact complex expectedly widespread, multivariate modelling still remains under‐explored in plants. Species of subfamily A sclepiadoideae ( pocynaceae) provide an opportunity study contrivances integrated by...
Effects of Pleistocene climatic oscillations on plant phylogeographic patterns are relatively well studied in forest, savanna and grassland biomes, but such impacts remain less explored desert regions the world, especially South America. Here, we performed a phylogeographical study Monttea aphylla, an endemic species Monte Desert, to understand evolutionary history vegetation communities inhabiting American Arid Diagonal. We obtained sequences three chloroplast (trnS–trnfM, trnH–psbA...
Monttea aphylla flowers simultaneously produce oil and nectar, rewards known to differentially attract ecologically functionally distinct pollinators.We examined whether geographical differentiation occurred for rewards, this could be explained by spatially heterogeneous pollinator guilds climate.Rewards were measured across the entire species range.Geographical patterns of reward quantity their relationships with biotic abiotic factors using uni-and multivariate analyses.Latitude...
Abstract Background and Aims Differences among populations in pollinator assemblages can lead to local adaptation mosaics which plants evolve different floral morphologies attractive traits. Mountain habitats may promote because of differences environmental conditions with altitude, causing changes pollinators, mountaintops act as isolated habitats. We studied if the shape, size nectar traits Salvia stachydifolia be attributed variations relative contribution hummingbirds insects. Methods...
Abstract The intraspecific evolutionary history of South American xerophytic plant species has been poorly explored. tree Prosopis chilensis a disjunct distribution in four regions: southern Peru, Bolivia, central–western Argentina and central Chile. Here, we combined phylogeographical (based on chloroplast nuclear markers), morphological climatic data to evaluate the relative contribution historical demo-stochastic adaptive processes differentiating areas distribution. results obtained with...
Abstract The joint effect of the Andes as a geographical barrier and Quaternary glaciations promoters genetic divergence remains virtually unexplored in southern South America. To help fill this knowledge gap, study we investigated demographic history Centris cineraria, solitary bee mainly distributed Patagonia. We used mitochondrial nuclear markers performed phylogeographical dating analyses, adjusted spatio-temporal diffusion species distribution models, Approximate Bayesian Computation to...
Abstract Background and Aims Diversity in pappus shapes size Asteraceae suggests an adaptive response to dispersion challenges adjusting diaspores optimal phenotypic configurations. Here, by analysing the relationship among pappus–cypsela relationships, flight performance types evolutionary context, we evaluate role of natural selection acting on evolution diaspore configuration at a macro-ecological scale daisy family. Methods To link relationships with collected published data these traits...
Despite Stebbins' principle of the most efficient pollinator being proposed decades ago, important pollinators are still mainly identified using frequency visits to flowers. This shortcoming results in a gap between characterization flower visitors plant species and reliable estimation fitness consequences mutualistic interaction. The performance visitor depends on its abundance, behaviour, effectiveness (pollen removal deposition per unit time) efficiency (seed set conditioned by temporal...
Abstract Geoclimatic events driving South American aridization have generated biota differentiation due to barriers and new environment formation. New environments allow species climatic niche evolution, or the geographical expansion of an existing one. Understanding role these processes play may clarify evolution biota. Gomphrena L. ranges across almost all continent's arid environments. We tested whether drylands are biogeographically connected through Gran Chaco but, different aridity...
La relación entre las plantas con flores y los polinizadores rara vez ocurre de a pares dado que la mayoría especies son visitadas por más una especie polinizadora. Un aspecto central es identificación visitantes florales ejercen el mayor efecto positivo sobre éxito reproductivo plantas. En Lepechinia floribunda (Lamiaceae), se ha observado nativos (Bombus spp) proporcionan un movimiento polen formación semillas en comparación exóticos (Apis mellifera). Sin embargo, aún desconoce cómo esta...
Interspecific interactions take place over both long and short time-frames. However, it is not completely understood if the interacting-partners persisted, migrated, or expanded in concert with Quaternary climate landscape changes. We aim to understand whether there concordance between specialist weevil Hydnorobius hydnorae its parasitic host plant, Prosopanche americana space time. determine had already established range, later actively colonized this rare resource; or, plant herbivore...
Pollination by animals is a key process involved in flowering plants reproduction. In the educational context, this topic rarely addressed from plant-pollinator interaction point of view, and its importance poorly recognized students. Here we present didactic proposal developed to address sexual reproduction plants, based on mutualistic association. The sequence activities includes display video, observation handling flowers fruits, as well play where pollination correspondence between...
