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.

Abstract Buzz pollination, a type of interaction in which bees use vibrations to extract pollen from certain kinds flowers, captures close relationship between thousands bee and plant species. In the last 120 years, studies buzz pollination have contributed our understanding natural history basic properties produced by applied flowers model systems. Yet, much remains be done establish its adaptive significance ecological evolutionary dynamics across diverse Here, we review for plants proximate (mechanism ontogeny) ultimate (adaptive evolution) explanations focusing especially on integrating these levels synthesize identify prominent gaps knowledge. Throughout, highlight new technical modelling approaches importance considering morphology, biomechanics behaviour shaping pollination. We end discussing context how multilevel perspective can contribute explain reasons this ancient bee–plant interaction.

Mycorrhizal symbiosis, seed dispersal, and pollination are recognized as the most prominent mutualistic interactions in terrestrial ecosystems. However, it remains unclear how these symbiotic relationships have interacted to contribute current plant diversity. We analyzed evolutionary among mycorrhizal type, dispersal mode, mode two global databases of 699 (database I) 10 475 II) tree species. Although database II had been estimated from phylogenetic patterns therefore lower certainty type than I, whose was determined by direct observation, allowed analysis many more taxa regions I. found evidence joint evolution all three features both databases. This result is robust effects sampling bias missing taxa. Most arbuscular mycorrhizal-associated trees endozoochorous (biotic) biotic pollination, with long distances, whereas ectomycorrhizal-associated anemochorous (abiotic) wind shorter distances. These results provide a novel scenario interactions, symbiosis types, which jointly evolved shaped diversity forest ecosystem world-wide.

Abstract. Ice-nucleating macromolecules (INMs) produced by plant pollen can nucleate ice at warm temperatures and may play an important role in weather- climate-relevant cloud glaciation. INMs have also proved useful for mammalian cell tissue model cryopreservation. The high nucleation (IN) activity of some indicates underlying biological function, either freezing tolerance or bioprecipitation-mediated dispersal. Here, using the largest study to date, we show that phylogenetic proximity, spermatophyte subdivision, primary growth biome, pollination season, method, desiccation native elevation do not account IN released from different species' pollen. results suggest these are plants a purpose unrelated incidental ability ice. This been adapted species specific purposes, producing exceptional nucleators. Pollen be more active, widespread nature, diverse than previously thought.

ABSTRACT The woody bamboos (Bambusoideae) exhibit distinctive biological traits within Poaceae, such as highly lignified culms, rapid shoot growth, monocarpic mass flowering and nutlike or fleshy caryopses. Much of the remarkable morphological diversity across subfamily exists a single hexaploid clade, paleotropical (PWB), making it ideal to investigate factors underlying evolution in bamboos. However, origin biogeographical history PWB remain elusive, does effect environmental on their characters. We generated robust time‐calibrated phylogeny using nucleotide polymorphisms retrieved from optimized double digest restriction site associated DNA sequencing, explored evolutionary trends habit, inflorescence, caryopsis type relation including climate, soil, topography. inferred that started diversify Oligocene–Miocene boundary formed four major clades, is, Melocanninae, Racemobambosinae s.l.

Our results provide novel insights into adaptive for future ecological research.

Summary Seeds are the main dispersal and propagation units of angiosperms. Examining relative allocation seed reserves by quantifying embryo size (ES) at (i.e. to seed) across angiosperms, sets basis track evolutionary history this key reproductive trait related germination timing offspring survival. We used a robust, dated phylogeny sampling ES for selected species most angiosperm families model macroevolution ES. Data on were collated from living specimens primary literature. Early angiosperms typically had low ES, which is still reflected in contemporary magnoliids ANA‐grade species. The analysis major shifts throughout revealed that these predominantly associated with formation lineages. tempo mode evolution not constant over history, paralleling paleo‐events. This study provides crucial new insights evolution, contribute understanding diversification strategies

Abstract The Paleozoic evolution of a complex terrestrial biota has been among the most important events in Earth history. Here, we synthesize paleontological and neontological information across different threads biota—including microbial life, fungi, animals, plants—addressing discrepancies between fossil record time-calibrated molecular phylogenies. Four fundamental patterns are emphasized: (1) Most animal lineages consist diminutive inhabitants soil litter, with fauna exhibiting remarkable continuity present. (2) Faunal tracks ecological opportunities afforded by land flora. Flora alike were initially confined to thin interface air, but animals explored both flight burrowing as vascular plant size increased encompass tree stature deep rooting. (3) Skewed nutrient ratios plants present challenge for that accommodated through contrasting size-based dietary strategies. Detritivory cell-by-cell herbivory diets readily available primary consumers impose limits on largest possible body sizes; only subsequent insects then vertebrates could dramatic increases Permian Mesozoic have achieved. (4) A second pulse terrestrializations is apparent Cretaceous Cenozoic might be attributed productivity associated angiosperm evolution. However, environmental changes availability earlier prevent an unambiguous causal attribution, may just artifact our modern vantage point.

ABSTRACT Aims Pollination plays a fundamental role in structuring the reproductive strategies and related traits of host plants. Active pollination is only observed nursery mutualistic systems. However, mechanisms underlying their maintenance are unclear. We aimed to explore factors shaping its global distribution pattern Ficus species specifically putting forward three questions: (1) actively‐pollinated more concentrated areas with older floras? (2) Is active better represented higher stable, less seasonal temperatures? (3) And also strongly arid areas? Location Global. Time Period Current. Major Taxa Studied pollinating fig wasps. Methods Using data 240 species, we constructed maps actively‐ passively‐pollinated estimated proportions 80 × km grid cells. assessed relative contribution climate conditions, sexual systems phylogenetic ages geographic variation frequencies using spatial autocorrelation analysis, linear model structural equation models. Results Neither nor passive randomly distributed. Actively‐pollinated prevalent regions proportion recently divergent floral elements. at lower latitudes stable temperatures, areas. Main Conclusions Our study provides comprehensive overview geographical modes species. Both evolutionary history current distributions modes. lineages that diverged associated relatively dry warm climates.

Abstract Mutualistic interactions are increasingly recognized as playing an important role in community assembly. We hypothesize that mutualisms can influence the amount of phylogenetic diversity within plant communities during test this hypothesis by comparing among clades Fabaceae (i.e. legumes), which has repeatedly gained and lost ability to form mutualistic symbiosis with nitrogen‐fixing bacteria (rhizobia). Here, we analysed global distribution data for both native introduced legumes quantified impact gains losses rhizobia trait on structure regional legume assemblages. Generally, find assemblages exhibit evidence clustering—lower than expected, suggesting species assembly is generally constrained conservation traits related More importantly, leveraging naturally existing variation rhizobial symbiosis, were able estimate contribution mutualism patterns clustering. Specifically, found relatively higher contain proportions non‐rhizobial legumes. Moreover, probability being recorded a new range negatively distance its nearest relative range, but effect significantly weaker not symbiotic rhizobia. Together, these results suggest contributes (1) clustering (2) through introduction establishment alien species. Synthesis . Our support establishing more strongly compatible locally available partners true do symbiosis. In addition, constraint occurs ranges. findings highlight significant (in bacterial rhizobia) play constraining across globe. study advances theory underscores importance considering restoration diversity.
