Abstract Species interactions are known to be key in driving patterns of biodiversity across the globe. Plant-plant through heterospecific pollen (HP) transfer by their shared pollinators is common and has consequences for plant reproductive success floral evolution, thus potential influence global community assembly. The literature on HP growing it therefore timely review causes among-species variation receipt at a scale, uncovering its contribution biodiversity. Here we analyzed published...
Abstract The number of co‐flowering species, floral density and trait diversity can be major determinants pollinator‐mediated plant–plant interactions in a community. However, evaluation how each one these components affects the pollination success single focal plant effects vary at different spatial scales, is lacking. Here, we evaluated functional (flower morphology colour), taxonomic (reflecting potential sampling effects) flower (conspecific heterospecific), on pollinator environment...
Abstract The ecological dynamics of co‐flowering communities are largely mediated by pollinators. However, current understanding pollinator‐mediated interactions primarily relies on how plants influence attraction shared pollinators, and much less is known about plant–plant that occur via heterospecific pollen (HP) transfer. Invaded in particular can be highly affected the transfer alien pollen, but strength, drivers fitness consequences these at a community scale not well understood. Here...
ABSTRACT The contribution of dipterans to pollination in tropical communities has been scarcely studied. Although some studies have evaluated dipteran crops and wild species, limited attention paid their role networks. In particular, pollen transport neglected. Integrating as floral visitors importance through interaction networks may help reveal co‐flowering communities. We constructed visitation from the analysis carried on bodies two coastal test prediction that would fewer but more...
Mexico is one of the most biodiverse countries in world, with an important proportion endemism mainly because convergence Nearctic and Neotropical biogeographic regions, which generate great diversity species turnover at different spatial scales. However, our knowledge Mexican ant biota limited to a few well-studied taxa, we lack comprehensive synthesis biodiversity information. For instance, available literature on fauna refers only lists by states, or focused regions country, prevents...
The interactions between pairs of native and alien plants via shared use pollinators have been widely studied. Community level studies however, are necessary in order to fully understand the factors mechanisms that facilitate successful plant invasion, but these still scarce. Specifically, few community considered how differences invasion (alien flower abundance), degree floral trait similarity invasive species, mediate effects on plant-pollinator communities. Here, we evaluated role species...
Abstract Species' floral traits and flowering times are known to be the major drivers of pollinator‐mediated plant–plant interactions in diverse co‐flowering communities. However, their simultaneous role mediating plant community assembly plant–pollinator is still poorly understood. Since not all species flower at same time, inference facilitative competitive based on trait distribution patterns should account for fine phenological structure (intensity overlap) within Such an approach may...
Abstract Uncovering the role of competition and facilitation in community assembly is central for developing a predictive understanding forces that organize biodiversity. Standard trait‐based approaches however rely on detection only one mechanism (competition or facilitation) along single trait even though pollinator‐mediated plant–plant interactions can be structured multiple phenotypic, phenological ecological traits. We evaluated plant species distribution phenotypic traits (flower...
Abstract Co‐flowering communities are usually characterized by high plant generalization but knowledge of the underlying factors leading to levels and pollinator sharing, how these may contribute network structure is still limited. Flowering phenology floral trait similarity considered among most important determining sharing. However, have been evaluated independently even though they can act in concert with each other. Moreover, importance flowering similarity, via their effects on...
Abstract Background and Aims Pollination failure occurs from insufficient pollen quantity or quality. However, the relative contributions of vs. quality to overall limitation, how this is affected by co-flowering context, remain unknown for most plant populations. Here, we studied patterns deposition tube formation across populations four predominately outcrossing species in genus Clarkia evaluate richness congeners affects contribution limitation. Methods We partition variation production...
A team of 79 scientists from more than 50 institutions partnered to gather all available information regarding Mexican ants since 1894, the year in which first geographical record an ant is known for country. In this new study, including 21,000 records, we showed that there are ~900 species Mexico, distributed unevenly across Mexico one relatively few countries along interface tropical and temperate zones, a megadiverse These photographs illustrate article “Mexico ants: incidence abundance...
Abstract The interactions between pairs of native and alien plants via shared use pollinators have been widely studied. Studies invasive species effects at the community level on other hand are still scarce. Few studies, however, considered how differences in intensity invasion, degree floral trait similarity species, can mediated plant-pollinator communities. Here, we evaluated effect overall network structure, species-level parameters, across nine coastal communities distributed along 205...
Abstract Heterospecific pollen transfer (HPT) is ubiquitous in co-flowering communities with strong implications for pollination success. may be especially relevant invaded plant communities. The mechanisms mediating HPT however remain poorly understood even though it could help better understand the outcome of invasions. In this study, we use structural equation modeling to evaluate role floral trait similarity and pollinator sharing success native plants coastal Our results show that...
