A Tale of Three Resources: The Influence of Multiple Resources on Plant-Herbivore Interactions
<p>Although studies indicate that plant growth can be co-limited by multiple resources, particularly water, nitrogen (N), and phosphorus (P), the role of co-limiting resources in driving plant-herbivore interactions remains poorly understood. Evidence indicates that the resources that limit plant …

MECHANISMS OF SUCCESS: PLANT-HERBIVORE INTERACTIONS AND THE INVASION OF NON-NATIVE LONICERA SPECIES IN NORTH AMERICA
… have been proposed to explain how invasive plant species are often poor competitors in their native range, but dominant in their novel range including the enemy release and novel weapons hypotheses. Additionally, many invasive species are characterized as being tolerant and/or resistant to …

Soil-plant-herbivore interactions and nutrient dynamics in semi-arid grazing systems in northeastern Brazil and western USA
… we evaluate how human-induced disturbances and interactions between soil, plants, and herbivores influence nutrient cycling, productivity, and ecosystem structure in semi-arid grazing systems in northeastern Brazil and Colorado, USA. We found that the presence of tree species within pastures of …

Bioinformatics and Next Generation Sequencing: Applications of Arthropod Genomes
… offer new insights into arthropod evolution and plant-herbivore interactions, open unique opportunities to develop novel plant protection strategies, and additionally, provide arthropod genomic resources as well.

Linking plant traits and herbivory in grassland biodiversity-ecosystem functioning research
… Here I propose a trait-based framework to merge plant-herbivore interactions with biodiversity-ecosystem function relationships. This framework links plant growth and defense strategies, herbivore feeding preferences, and primary production in terrestrial plant communities. I empirically tested …

BIOLOGICAL CONTROL: EFFECTS OF TYRIA JACOBAEAE ON THE POPULATION DYNAMICS OF SENECIO JACOBAEA IN NORTHWEST MONTANA
… insects is a common strategy for controlling plant invasions. However, the efficacy of biological control agents in controlling their host plants is rarely quantified population level. I quantified the impact of a specialist biological control agent, the cinnabar moth <i>(Tyria jacobaeae)</i> …

Biogeographical Approaches for Studying Species Invasion
… genotypes of P. australis in relation to plant-herbivore interactions in North America. Common garden experiments revealed that the native and invasive genotypes of P. australis have evolved latitudinal clines on traits associated with herbivory, specifically for aphid Hyalopterus pruni. …

In defence of flowers: The ecology and biochemistry of a chemical defence, cyanogenesis, in Proteaceae
As sessile organisms, plants produce a remarkable diversity of chemicals to defend their tissues against herbivory. The large body of research into plant defences has primarily focused on plant-herbivore interactions and foliar defences, whereas floral chemical defences have received little …

Seaweed Invasions and Novel Chemical Defences
… It has commonly been predicted that introduced plants will invade when they are less affected by herbivores, since this will provide the introduced species with a competitive advantage over native plants. Furthermore, it has been suggested that introduced species with chemical defences that are …

The adaptive potential of plant endopolyploidy in response to herbivory
Damage caused by herbivores is a potentially strong selective agent of plant phenotypes, including selecting for many defensive traits, though not all plant-herbivore interactions are strictly negative for the plants. Overcompensation is the increase in components of fitness (flower, fruit, and/or …
