Indirect defence via tritrophic interactions

M Heil - New Phytologist, 2008 - Wiley Online Library
Many plants interact with carnivores as an indirect defence against herbivores. The release
of volatile organic compounds (VOCs) and the secretion of extrafloral nectar (EFN) are …

Ecological role of volatiles produced by plants in response to damage by herbivorous insects

JD Hare - Annual review of entomology, 2011 - annualreviews.org
Plants often release a blend of volatile organic compounds in response to damage by
herbivorous insects that may serve as cues to locate those herbivores by natural enemies …

Extrafloral nectar at the plant-insect interface: a spotlight on chemical ecology, phenotypic plasticity, and food webs

M Heil - Annual review of Entomology, 2015 - annualreviews.org
Plants secrete extrafloral nectar (EFN) as an induced defense against herbivores. EFN
contains not only carbohydrates and amino acids but also pathogenesis-related proteins …

The multiple faces of indirect defences and their agents of natural selection

A Kessler, M Heil - Functional Ecology, 2011 - Wiley Online Library
Plants commonly attract predatory and parasitoid organisms, and may thereby increase
resistance against antagonistic herbivores. Mechanisms for indirect resistance include the …

Can optimal defence theory be used to predict the distribution of plant chemical defences?

AC McCall, JA Fordyce - Journal of Ecology, 2010 - Wiley Online Library
The optimal defence theory (ODT) of chemical defence provides a predictive framework for
the distribution of anti‐herbivore defences in plants. One of its predictions is that chemical …

Defence on demand: mechanisms behind optimal defence patterns

S Meldau, M Erb, IT Baldwin - Annals of botany, 2012 - academic.oup.com
Background The optimal defence hypothesis (ODH) predicts that tissues that contribute most
to a plant's fitness and have the highest probability of being attacked will be the parts best …

Multitrophic interactions below and above ground: en route to the next level

NM van Dam, M Heil - Journal of Ecology, 2011 - Wiley Online Library
Plants mediate multiple interactions between below‐ground (BG) and above‐ground (AG)
heterotrophic communities that have no direct physical contact. These interactions can be …

A specialist root herbivore exploits defensive metabolites to locate nutritious tissues

CAM Robert, N Veyrat, G Glauser, G Marti… - Ecology …, 2012 - Wiley Online Library
Ecology Letters (2011) 14: 55–64 Abstract The most valuable organs of plants are often
particularly rich in essential elements, but also very well defended. This creates a dilemma …

Optimal defense theory in an ant–plant mutualism: extrafloral nectar as an induced defence is maximized in the most valuable plant structures

ES Calixto, D Lange, J Bronstein… - Journal of …, 2021 - Wiley Online Library
Plants allocate defences in order to decrease costs and maximize benefits against
herbivores. The Optimal Defense Theory (ODT) predicts that continuously expressed (ie …

Insect herbivore‐associated organisms affect plant responses to herbivory

F Zhu, EH Poelman, M Dicke - 2014 - Wiley Online Library
In nature, plants interact with many organisms and need to integrate their responses to these
diverse community members. Knowledge on plant–insect relationships has accumulated …
