Abstract Premise Many angiosperms have evolved specialized systems that promote pollination by specific taxa. Therefore, plant distributions may be limited the local abundance of their specialist pollinators. In eastern North America, Lobelia cardinalis is thought to pollinated solely Archilochus colubris , only hummingbird species found in region. Here we tested hypothesis distribution a with controlled range and its pollinator. Methods We investigated importance A. abundance, sourced from eBird, as variable MaxEnt model L. using presence data iNaturalist. also compared between locations congeneric during respective flowering periods explored whether congenerics align week peak abundance. Results Unexpectedly, modelling did not suggest key driver distribution. habitat suitability was lowest absence increased increasing but low regions where highest. Still, at generally higher than most congenerics, tended flower near Conclusions While populations hummingbird‐pollinated require hummingbirds, fine‐scale variation strongly influence spatial distributions.

The number of angiosperms that may depend on animals for pollination has been difficult to estimate because the modes tens thousands species tall trees, canopy climbers, and epiphytes, especially from tropics, remain unknown. Ecological research over past 50 years, however, established a strong correlation between by wind or water particular flower traits. Based literature search pollination-ecological data families, genera, compiled Global Biological Information Facility (GBIF) World Flora Online (WFO) databases, we estimated with abiotic then subtracted it total taxa. results show based GBIF, 68% 465 88% 14,437 90% 332,341 rely animal pollination.

Finding all angiosperm cross reinforces importance prioritizing conservation plant-pollinator interactions natural agricultural ecosystems.

Interactions with angiosperms have been hypothesised to play a crucial role in driving diversification among insects, particular emphasis on pollinator insects. However, support for coevolutionary insect-plant interactions is weak. Macroevolutionary studies of insect and plant diversities the hypothesis that diversified after peak diversity Early Cretaceous. Here, we used family-level fossil record insects as whole, families particular, estimate rates macroevolutionary history using Bayesian process-based approach.

Since the insights by Charles Darwin, heterostyly, a floral polymorphism with morphs bearing stigmas and anthers at reciprocal heights, has become model system for study of natural selection. Based on his archetypal heterostylous flower, including regular symmetry, few stamens tube, Darwin hypothesised that heterostyly evolved to promote outcrossing through efficient pollen transfer between involving different areas pollinator's body, thus proposing seminal pollination-precision hypothesis. Here we update number other style-length polymorphic taxa 247 genera belonging 34 families, notably expanding known cases 20%. Using phylogenetic comparative analyses across angiosperms, show numerous independent origins associated actinomorphic, tubular flowers low sex organs, fused corolla, pollination long-tongued insects. These associations provide support Darwinian hypothesis as basis convergent evolution angiosperms.

Abstract Background and Aims Fire may favour plant flowering by opening up the vegetation increasing abiotic resource availability. Increased floral display size can attract more pollinators increase absolute fruit seed production immediately after a fire. However, anthropogenic increases in fire frequency alter these responses. We aim to assess effects of on pollination reproductive success plants at global scale. Methods performed systematic literature review meta-analyses examine overall as well different parameters reproduction. also explored what extent responses vary among pollinators, vectors, regeneration strategies, compatibility systems, types biomes. Key Results Most studies were conducted fire-prone ecosystems. Overall, single fires increased reproduction but this effect was overridden recurrent fires. Floral visitation rates enhanced following wildfire, especially bee-pollinated plants. fruits or seeds not set. The benefits mostly observed wind-pollinated (graminoids), herbaceous resprouter species. Finally, positively correlated with success.

Plant pollination by insects represents one of the most transformative and iconic ecological relationships in natural world. Despite tens thousands papers, as well numerous books, on biology published over past 200 years, studies focused fossil record pollinating have only been last few decades, this field is still undergoing major developments. Current palaeontological evidence indicates that were diverse participated reproduction different gymnosperm lineages long before their association with flowering plants (angiosperms). However, since much literature remains unfamiliar to many scientists working extant plant-pollinator interactions, wider public, notion insect began origin angiosperms widespread. Herein we highlight how all known orders and/or extinct pollinator representatives radiated evolution plants. We also illustrate changing composition fauna through time, reflecting nature these communities compared those existing today. Addressing plant from a perspective skewed towards present-day biological groups, patterns, processes risks missing an important deep-time evolutionary component. Our conclusions show fundamental elucidating pollination, informing interactions.

ABSTRACT Plant–hummingbird interactions are considered a classic example of coevolution, process in which mutually dependent species influence each other's evolution. Plants depend on hummingbirds for pollination, whereas rely nectar food. As step towards understanding this review focuses the macroevolutionary consequences plant–hummingbird interactions, relatively underexplored area current literature. We synthesize prior studies, illustrating origins and dynamics hummingbird pollination across different angiosperm clades previously pollinated by insects (mostly bees), bats, passerine birds. In some cases, crown age pre‐dates plants they pollinate. other plant groups transitioned to early establishment bird group Americas, with build‐up both diversities coinciding temporally, hence suggesting co‐diversification. Determining what triggers shifts away from remains major open challenge. The impact diversification is complex, many tropical lineages experiencing increased after acquiring flowers that attract hummingbirds, others no change or even decrease rates. This mixed evidence suggests extrinsic intrinsic factors, such as local climate isolation, important covariables driving adapted pollination. To guide future we discuss mechanisms contexts under clade individual (e.g. traits, foraging behaviour, degree specialization), could conclude commenting how signals mutualism relate highlighting unbalanced focus side interaction, advocating use species‐level interaction data studies.

Summary Flowers are the complex and highly diverse reproductive structures of angiosperms. Because their role in sexual reproduction, evolution flowers is tightly linked to angiosperm speciation diversification. Accordingly, quantification floral morphological diversity (disparity) among subgroups through time may give important insights into evolutionary history angiosperms as a whole. Based on comprehensive dataset focusing 30 characters describing structure across angiosperms, we used 1201 extant 121 fossil measure disparity explore patterns lineages. We found that reached highest Early Cretaceous. However, decreasing toward present likely has not precluded innovation other traits at levels, which played key outstanding species richness. Angiosperms occupy specific regions theoretical morphospace, indicating only portion possible trait combinations observed nature. The ANA grade, magnoliids, early‐eudicot grade large areas morphospace (higher disparity), whereas nested groups narrower (lower disparity).
