Plant-soil feedbacks and interspecific competition are ubiquitous interactions that strongly influence the performance of plants. Yet few studies have examined whether strength these corresponds with abundance plant species in field, or interact ways either ameliorate exacerbate their effects isolation. We sampled soil from two intermountain grassland communities where we also measured relative species. In greenhouse experiments, quantified direction magnitude plant-soil for 10 target...
Invasive plant impacts vary widely across introduced ranges. We tested the hypothesis that differences in eco‐evolutionary experience of native communities with invader correspond invasive species on vegetation, increasing ecological novelty. compared richness and composition beneath Pinus contorta to adjacent vegetation other P. stands a network sites its (Canada USA) non‐native (Argentina, Chile, Finland, New Zealand, Scotland, Sweden) At North America Europe, within natural distribution...
Alpine grassland vegetation supports globally important biodiversity and ecosystems that are increasingly threatened by climate warming other environmental changes. Trait-based approaches can support understanding of responses to global change drivers consequences for ecosystem functioning. In six sites along a 1314 m elevational gradient in Puna grasslands the Peruvian Andes, we collected datasets on vascular plant composition, functional traits, biomass, fluxes, data over three years. The...
We describe a method for simultaneous single-molecule optical and electrical characterization of membrane-based sensors that contain ion-channel nanopores. The technique is used to study the specific nonspecific interactions streptavidin-capped DNA polymers with lipid bilayers composed diphytanoyl phosphatidylcholine phosphatidylglycerol. Biotinylated bound fluorescently labeled streptavidin electrophoretically driven into, or away from, lumen alpha hemolysin (αHL) ion channels by an...
Abstract Aims Within-species genetic and phenotypic variation have well-known effects on evolutionary processes, but less is known about how within-species may influence community-level processes. Ecologically meaningful intraspecific might be particularly important in the context of anthropogenic impacts natural systems, such as agriculture species invasion, because human actions can cause strong selection pressures. Methods In a greenhouse study, we explored (30 accessions) ecotypic...
Relatives often interact differently with each other than nonrelatives, and whether kin cooperate or compete has important consequences for the evolution of mating systems, seed size, dispersal, competition. Previous research found that larger size dimorphic seeds produced by annual plant Aegilops triuncialis suppressed germination their smaller sibs 25%-60%. Here, we evidence recognition sibling rivalry later in life among seedlings places seed-seed interactions a broader context. In...
Coordination cages encapsulate a wide variety of guests in the solution state. This ability renders them useful for applications such as catalysis and sequestration precious materials. Here we report simple general method immobilisation coordination on alumina. Cage loadings were quantified via adsorption isotherms guest displacement assays demonstrated that adsorbed retained to separate non-guest molecules. Finally, used system two different regions alumina stabilise pair Diels-Alder...
