A communal catalogue reveals Earth’s multiscale microbial diversity
A meta-analysis of microbial community samples collected by hundreds of researchers for the Earth Microbiome Project is presented, creating both a reference database giving global context to DNA sequence data and a framework for incorporating data from future studies, fostering increasingly complete characterization of Earth’s microbial diversity.

A phylogenetically controlled meta-analysis comparing insect herbivore resistance and putative plant defence traits between crops and their wild relatives found that domestication consistently reduced plant resistance to herbivores, although the magnitude of the effects varied across plant organs and depended on how resistance was measured.
The many dimensions of phytochemical diversity: linking theory to practice.
It is argued that the phytochemical diversity experienced by an organism (or observed by a researcher) depends strongly on the scale of the interaction and the total amount of phytochemicals involved, and it must account for these frames of reference to meaningfully understand diversity.
Herbivore‐induced changes in fruit–frugivore interactions
Novel evidence is provided that induced responses to herbivory can affect fruit–frugivore interactions through two mechanisms: changes in fruit palatability and changes in Fruit development time.
Interaction diversity explains the maintenance of phytochemical diversity.

Results show how phytochemical diversity may be maintained in nature by a complex selective landscape exerted by diverse communities of plant consumers.
Effect of Washing, Waxing and Low-Temperature Storage on the Postharvest Microbiome of Apple
It is revealed that tissue-type is the main factor defining fungal and bacterial diversity and community composition on apple fruit, and fungi and bacteria were impacted equally by sanitation practices, especially the epiphytic microflora of peel tissues.
Iridoid and secoiridoid glycosides in a hybrid complex of bush honeysuckles (Lonicera spp., Caprifolicaceae): implications for evolutionary ecology and invasion biology.
Chemical ecology of fruit defence: synergistic and antagonistic interactions among amides from Piper
The results suggest that the secondary metabolites in fruits may be a key characteristic contributing to fruit defence and plant reproductive success.

This article explores how agricultural practices and evolutionary changes in domesticated species cause evolution in wild species by examining three processes by which agriculture drives evolution, and discusses their ecological and sociological impacts.
Evidence for the Adaptive Significance of Secondary Compounds in Vertebrate-Dispersed Fruits
It is concluded that the adaptive significance of chemical traits is best considered in a whole-plant context that includes fruit-frugivore interactions, including higher concentrations and more individual compounds in fruits compared to leaves and a negative relationship between iridoid glycoside concentration and fruit damage.
