Effects of pyric herbivory on prairie-chicken (Tympanuchus spp) habitat.

open access: yesPLoS ONE, 2020
The reduction and simplification of grasslands has led to the decline of numerous species of grassland fauna, particularly grassland-obligate birds.

Elevational changes in insect herbivory on woody plants in six mountain ranges of temperate Eurasia: Sources of variation

open access: yesEcology and Evolution, 2022
Current theory predicts that the intensity of biotic interactions, particularly herbivory, decreases with increasing latitude and elevation. However, recent studies have revealed substantial variation in both the latitudinal and elevational patterns of ...

Distributions of photosynthetic traits, shoot growth, and anti-herbivory defence within a canopy of Quercus serrata in different soil nutrient conditions

open access: yesScientific Reports, 2021
The hypothesis of the present study is that not only distributions of leaf photosynthetic traits and shoot growth along light gradient within a canopy of forest trees, but also that of leaf anti-herbivory defence capacities are influenced by soil ...

Understanding plant community responses to combinations of biotic and abiotic factors in different phases of the plant growth cycle [PDF]

open access: yes, 2012
Understanding plant community responses to combinations of biotic and abiotic factors is critical for predicting ecosystem response to environmental change.

Determinants of herbivory on seedlings in a subtropical forest: Insights from plant apparency, Janzen-Connell effects, and functional traits

open access: yesPlant Diversity
Herbivory is widely known to play a critical role in structuring plant communities. However, much less is known about what factors determine herbivory in forest ecosystems.

Insect herbivory increases from forest to alpine tundra in Arctic mountains

open access: yesEcology and Evolution, 2022
Current theory holds that the intensity of biotic interactions decreases with increases in latitude and elevation; however, empirical data demonstrate great variation in the direction, strength, and shape of elevational changes in herbivory.

Resistance and susceptibility of milkweed: competition, root herbivory, and plant genetic variation [PDF]

open access: yes, 2004
Beetles in the genus Tetraopes share a long evolutionary history with milkweeds (Asclepias spp.), feeding on roots as larvae and leaves as adults. Despite their extreme specialization on milkweed, Tetraopes require drying grass stems as oviposition sites,

Transgenerational Consequences of Plant Responses to Herbivory: An Adaptive Maternal Effect [PDF]

open access: yes, 2000
Herbivory has many effects on plants, ranging from shifts in primary processes such as photosynthesis, growth, and phenology to effects on defense against subsequent herbivores and other species interactions.

Drought Stress Mediated Changes in Food Crops: Mechanisms and Remediation Strategies

open access: yesAdvanced Science, EarlyView.
This work presents a multi‐scale framework for flavonoid‐mediated drought tolerance in staple food crops, integrating ROS redox regulation, antioxidant defense, rhizosphere microbial interactions, and sustainable agronomic practices. This interdisciplinary model provides core insights to develop climate‐resilient cropping systems and enhance global ...

Aboveground herbivory suppresses the arbuscular mycorrhizal symbiosis, reducing plant phosphorus uptake

open access: yes, 2021
Most terrestrial plants form associations with arbuscular mycorrhizal (AM) fungi, which are soil-dwelling microbial symbionts that provide plants with soil nutrients, while plants supply the fungi with carbon.
