“…The flowers of populations inhabiting the Andean forest present a smaller operative distance (hereafter "OD," Figure 2), that is, the distance between floral reward and the fertile parts, than those located in the steppe. This OD matches the sizes of their most frequent pollinators: the large bee Centris cineraria and the small bee Chalepogenus caeruleus, which differ significantly in their body lengths (Cosacov et al, 2010(Cosacov et al, , 2014Sosa-Pivatto et al, 2017). Several bidirectional transitions between the large and the small oilcollecting bee species can be inferred from the intraspecific differentiation of C. polyrhiza (Figure S1).…”

Organism shape changes predictably during ontogeny, resulting in specific patterns of ontogenetic allometry. In several plant and animal lineages, among‐species variation in the shape of mature organisms mirrors variation along their growth trajectories. Hence, ontogenetic allometry is an important bias in evolution. This bias should be stronger at reduced evolutionary time scales, in which among‐trait correlations had less time to evolve. Nevertheless, it was shown that adaptation of organism shape frequently involved departures from the ancestral ontogenetic allometry. Moreover, only a moderate fraction of shape variation is correlated with size during ontogeny. Hence, nonallometric variation in shape (NAVSh) is likely to contribute to adaptation, even at reduced evolutionary time scales. We explored the contributions of allometric variation in shape (AVSh), NAVSh, and size variation to adaptive evolution in the angiosperm species Calceolaria polyrhiza. This strongly relies on oil‐collecting bees for pollination and experienced transitions in the size of pollinators during the last 2 Ma. Using geometric morphometrics, we described corolla morphology in several populations across its distribution range. Variation in corolla shape was decomposed into an allometric and a nonallometric component, and corolla size was estimated. We then looked for the correlation between these aspects of morphology and the pollinator. Our results suggest that adaptation to pollinators with different sizes relied on NAVSh, which resulted from shifts in the allometric slope and from shape changes that occurred early in flower development. We conclude that NAVSh can contribute to adaptation in flowering plants, even at the species‐level.

“…This provides evidence for the long-term persistence of a "three-way" interspecies interaction (Prosopis-Prosopanche-Hydnorobius) in the Monte desert. Some other enduring two-way associations between insects and South American plants have been reported for weevils and beetles feeding on relictual ancient conifers [85][86][87][88][89], and for two oil-collecting bee species and the perennial endemic herbs they pollinate [6]. More generally, an old history of specialized insect-plant interactions has been suggested as a main contributing factor to current biodiversity in the Patagonian region [90].…”

“…In addition, information from paleoclimatic conditions and the fossil record indicates that plants of genus Prosopis (Fabaceae), the host of P. americana, were abundant during the Miocene (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23) and Lower Pliocene (1-5 Mya) [80,81] in Northern Argentina. In essence, evidence suggests that the evolution and diversification of Prosopis took place jointly with the expansion of arid areas in the American continent, after the Andean uplift in the late Miocene [82].…”

“…For example, from this perspective, numerous studies are suggesting that climatic oscillations during the last million years (i.e., the Late Quaternary) had a major impact not only on species distribution, but also on their demography and diversification [5]. However, it is less clear how biological interactions may modulate organisms' responses to these climatic changes (but see [6]). Although the importance of interspecific interactions in the evolution of the species at a geographical scale is recognized [7,8], it is not completely understood whether or not the interacting-partners responded in the same way to Quaternary climate and landscape changes (that is if they survived or expanded together in the landscape [6]).…”

Unveiling the History of a Peculiar Weevil-Plant Interaction in South America: A Phylogeographic Approach to Hydnorobius hydnorae (Belidae) Associated with Prosopanche americana (Aristolochiaceae)

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 and landscape changes. We aim to understand whether there is concordance between the specialist weevil Hydnorobius hydnorae and its parasitic host plant, Prosopanche americana in space and time. We aim to determine whether Prosopanche had already established its range, and Hydnorobius later actively colonized this rare resource; or, if both host plant and herbivore expanded their range concomitantly. We performed population genetic, phylogeographic and Bayesian diffusion analysis of Cytochrome B sequences from 18 weevil localities and used paleodistribution models to infer host plant dispersal patterns. We found strong but uneven population structure across the range for H. hydnorae with weak signals of population growth, and haplotype network structure and SAMOVA groupings closely following biogeographic region boundaries. The ancestral areas for both Hydnorobius and Prosopanche are reconstructed in San Luis province within the Chaco Biogeographic province. Our results indicate a long trajectory of host-tracking through space and time, where the weevil has expanded its geographic range following its host plant, without significant demographic growth. We explore the past environmental changes that could underlie the boundaries between locality groups. We suggest that geographic dispersal without population growth in Hydnorobius could be enabled by the scarcity of the host plant itself, allowing for slow expansion rates and stable populations, with no need for significant demographic growth pulses to support range expansion.

PremiseThe interaction between ecological and evolutionary processes has been recognized as an important factor shaping the evolutionary history of species. Some authors have proposed different ecological and evolutionary hypotheses concerning the relationships between plants and their pollinators, and a special case is the interaction and suspected coevolution among Agave species and their main pollinators, the Leptonycteris bats. Agave species have in general a pollination syndrome compatible with chiropterophily, including floral shape and size, nocturnal nectar production, and nectar quality and sugar concentration. Our goal was to analyze the interaction Agave‐Leptonycteris and its dynamics during three different climate scenarios.MethodsWe modeled the Agave‐Leptonycteris interaction in its spatial and temporal components during Pleistocene, we used Ecological Niche Models (ENMs) and three climate scenarios: Current, Last Glacial Maximum (LGM), and Last InterGlacial (LIG). Further, we analyzed the geographic correlation between 96 Agave species and two the Mexicans Tequila bats, genus Leptonycteris.ResultsWe found that Leptonycteris species interact with different Agave species over their migratory routes. We propose an interaction refuge in Metztitlán and Tehuacán‐Cuicatlán areas, where Agave‐ Leptonycteris interaction has probably remained active. During the non‐migratory season, both bat species consume nectar of almost the same Agave species, suggesting the possibility of a diffuse coevolution among Agave and Leptonycteris bats.ConclusionsWe propose that in the areas related to migratory bat movements, each bat species interacts with different Agave species, whereas in the areas occupied by non‐migrant individuals, both bat species consume nectar of almost the same Agave taxa.This article is protected by copyright.
