Aphids increase their rate of survival on emergent aquatic plants through niche construction.

Flooding or rain is a threat to many insects in nature, including herbivorous invertebrates whose hosts are emergent aquatic plants. They may thus have developed particular adaptations to withstand the flooding that is a feature of emergent plants' environment. The aphid Hyalopterus pruni (Hemiptera: Aphididae) modifies the physical and chemical conditions of its habitat by periodically spreading wax around itself with its hind legs.

Plant-plant interaction by Aster leiophyllus affects herbivory by Sika deer, Cervus nippon.

Changes in leaf traits in response to plant-plant interactions affect feeding by insect herbivores. However, the effects of such changes on feeding by vertebrate herbivores remain unclear. We examined the effects of interactions of Aster leiophyllus collected in the field (growing with plants of the same species [aggregated] or with plants of different species [solitary]) or grown in pots (with another A.

Effects of indirect plant-plant interaction via root exudate on growth and leaf chemical contents in .

Belowground plant-plant interactions can affect the concentrations of leaf chemicals, but the mechanism is not clear. Here, we investigated the effects of intra- and interspecific root exudates on the growth and leaf chemical content of . Seedlings of were grown with exposure to root exudates collected from other plants or from , or plants, and the total phenolic, condensed tannin, dry biomass, and chlorophyll contents of the leaves were examined.

Damage to leaf veins suppresses root foraging precision.

Premise: Plants generally increase root growth in areas with high nutrients in heterogeneous soils, a phenomenon called foraging precision. The physiology of this process is not well understood, but it may involve shoot-root signaling via leaf veins. If this is true, then damage to leaf veins, but not to nearby mesophyll, would reduce plant foraging precision.

Self-discrimination in vine tendrils of different plant families.

Previous study reported a novel type of self-discrimination in the tendrils of the vine Cayratia japonica (Vitaceae). However, whether self-discrimination in tendrils is common in vine plant species has not been elucidated. Here, we investigated whether tendrils of Momordica charantia var.
