Does anthropogenic nitrogen deposition induce phosphorus limitation in herbivorous insects? [PDF]
, 2012 Anthropogenic nitrogen deposition has shifted many ecosystems from nitrogen ( N ) limitation to phosphorus ( P ) limitation. Although well documented in plants, no study to date has explored whether N deposition exacerbates P limitation at ...

PLoS ONE, 2022 The preference-performance hypothesis explains host specificity in phytophagous insects, positing that host plants chosen by adults confer the greatest larval fitness. However, adults sometimes oviposit on plants supporting low larval success because the

Functional Profiles of Phyllosphere and Rhizosphere Metagenomes Differ Across Milkweed Species [PDF]
Environ Microbiol RepWe characterised milkweed microbiomes using a metagenomics approach to investigate the functional potential of endophytic phyllosphere and rhizosphere communities. We found evidence that the composition of potential PSM genes varied across milkweeds in spp. specific responses, for both phyllospheres and rhizospheres, and in response to monarch feeding.

Two New Cyototoxic Cardenolides from the Whole Plants of Adonis multiflora Nishikawa & Koki Ito
Molecules, 2015 A phytochemical investigation of the whole plants of Adonis multiflora Nishikawa & Koki Ito. resulted in the isolation and identification of two new cardenolides—adonioside A (1) and adonioside B (6)—as well as four known cardenolides: tupichinolide (

Plant‐derived differences in the composition of aphid honeydew and their effects on colonies of aphid‐tending ants [PDF]
, 2014 In plant–ant–hemipteran interactions, ants visit plants to consume the honeydew produced by phloem‐feeding hemipterans. If genetically based differences in plant phloem chemistry change the chemical composition of hemipteran honeydew, then the plant's ...
