Insect herbivory fluctuations through geological time

Ecology, 2016
AbstractArthropods and land plants are the major macroscopic sources of biodiversity on the planet. Knowledge of the organization and specialization of plant–herbivore interactions, such as their roles in food webs is important for understanding the processes for maintaining biodiversity.

Insect herbivory and woody plants

1982
Wood is persistent and woody plants may live to a great age. An important reason for this is that relatively few insects have evolved to exploit wood in living plants. Most species feed on the softer and more transient tissues of woody plants such as leaves, fine roots, flowers, fruits and to a lesser extent the meristems.

Insect herbivory and the plant community

1982
In this chapter we will examine how plant communities can modify, either directly or indirectly, the abundance and population dynamics of their associated insect herbivores and, conversely, how insect herbivores might alter the composition of plant communities [163].

Insect herbivory on an inland brackish wetland

Wetlands, 1988
Standing crop measurements were made in emergent wetland vegetation following acute herbivory by 2 species of leaf-chewing caterpillars,Cisseps fulvicula (Ctenucidae) andAcronicta leporina (Noctuidae). Significant weight differences were found between grazed and ungrazed stands of alkali bulrush, cattail, Olney’s bulrush, and saltgrass, respectively ...

Specificity and context-dependency of plant-plant communication in response to insect herbivory.

Current Opinion in Insect Science, 2019
Over three decades of work on airborne plant communication have taught us that plants send, receive, and respond to volatile organic compounds (VOCs) emitted by conspecific as well as heterospecific neighbouring plants.

Biases in studies of spatial patterns in insect herbivory

Ecological Monographs, 2019
The properties of the human mind are responsible for a number of biases that affect the quality of scientific research. However, scientists working in the fields of ecology and environmental science rarely take these biases into account.

Intercropping Alters Phytochemicals Associated With Insect Herbivory

Journal of Chemical Ecology
Given the multiple possible mechanisms for interspecific chemical interaction between adjacent heterospecific plants, phytochemical profiles, which include phytochemical defense compounds, of crop species could potentially be enhanced or altered by intercropping with phytochemically diverse neighbors.

Plant Resistance to Insect Herbivory

2011
Plants are the major food source for most insects. While insects have developed various feeding strategies, plants respond by activating distinct signaling pathways resulting in the production of defensive compounds. Important regulators in this signaling system are compounds in the insect saliva, which are often modified plant molecules.

Deciduous leaf drop reduces insect herbivory

Oecologia, 2007
Deciduous leaf fall is thought to be an adaptation that allows plants living in seasonal environments to reduce water loss and damage during unfavorable periods while increasing photosynthetic rates during favorable periods. Observations of natural variation in leaf shedding suggest that deciduous leaf fall may also allow plants to reduce herbivory.

Plant Defenses Against Insect Herbivory

2010
Herbivory, the act of consumption of plant biomass by specialist animals, regulates the cycling of biotic and abiotic ecosystem components, through a complex process transferring materials among various trophic levels. Herbivores include insects and mammals of varying sizes, the former being most important due to their high diversity.
