Understanding the phytochemical diversity of plants: Quantification, variation and ecological function

This paper examines phytochemical diversity (chemodiversity) in plants, discussing its ecological relevance, reviewing methodological practices, and outlining future research directions.

Tolerance to land-use changes through natural modulations of the plant microbiome

The paper shows that natural changes in the plant microbiome enhance plant tolerance to land-use changes by affecting phenotype and performance, outperforming direct environmental manipulations.

Geographic distribution of terpenoid chemotypes in Tanacetum vulgare mediates tansy aphid occurrence and abundance

This study examines how geographic variation in tansy's terpenoid chemotypes influences aphid and ant communities across Germany.

Floral volatiles evoke partially similar responses in both florivores and pollinators and are correlated with non-volatile reward chemicals

The paper compares how pollinators and florivores respond to floral volatiles and non-volatile chemicals, finding florivores detect more volatiles and some compounds are attractive to both groups.

Quantifying chemodiversity considering biochemical and structural properties of compounds with the R package chemodiv

The paper introduces the R package chemodiv to quantify chemodiversity by incorporating biochemical and structural properties of compounds.

Digital whole-community phenotyping to assess morphological and physiological features of plant communities in the field

This study introduces a digital whole-community phenotyping method to track plant community responses to land-use treatments, showing it captures morphological and physiological changes more effectively than manual methods.

qad: An R-package to detect asymmetric and directed dependence in bivariate samples

The paper introduces qad, a non-parametric method to detect directed and asymmetric dependence in bivariate samples, and demonstrates its application on ecological datasets.

Accuracy of mutual predictions of plant and microbe communities varies along a successional gradient in an alpine glacier forefield

The paper examines how accurately plant and microbe communities predict each other and environmental factors across a glacier forefield successional gradient.

Divergent assembly trajectories: a comparison of the plant and soil microbiome with plant communities in a glacier forefield

The paper compares community assembly processes between plant, soil microbiome, and leaf microbiome in a glacier forefield, finding differences in dispersal limitation, environmental response, and species specificity.

Succession comprises a sequence of threshold-induced community assembly processes towards multidiversity

The paper shows that in a glacier forefield, community assembly shifts from dispersal-dominated to niche-based processes after 60 years of succession, supported by declining multi-beta-diversity.

Photodynamic Inactivation reduces the diversity and changes the composition of bacterial and fungal communities associated with leaf surfaces

The paper shows that photodynamic inactivation reduces microbial diversity and changes community composition on plant leaves.

Changes amid constancy: flower and leaf microbiomes along land use gradients and between bioregions

This study examines flower and leaf microbiomes of two plant species across bioregions and land use gradients, finding differences in community structure and responses to environmental factors.

Bacteria associated with flowers affect the reproductive success of Brassica napus L. via scent-mediated interactions with pollinators

This study shows that floral bacteria affect the reproductive success of Brassica napus by altering floral scent and pollinator behavior.

Myco- and photobiont associations in crustose lichens in the McMurdo Dry Valleys (Antarctica) reveal high differentiation along an elevational gradient

This study examines myco- and photobiont associations in crustose lichens across an elevational gradient in the McMurdo Dry Valleys, finding elevation-driven patterns in species distribution and network specialization.

Microclimatic effects on alpine plant and flower visitor communities and their interactions

This study shows microclimatic heterogeneity in alpine pastures affects plant and insect communities and their interactions, suggesting microclimates may buffer climate warming effects.
