Herbivore preference drives plant community composition.
Herbivores are important drivers of plant species coexistence and community assembly. However, detailed mechanistic information on how herbivores affect dominance hierarchies between plant species is scarce. Here, we used data of a multi-site herbivore exclusion experiment in grasslands to assess changes in the cover of 28 plant species in response to aboveground pesticide. application. Moreove...
متن کاملUrban Land Use Decouples Plant-Herbivore-Parasitoid Interactions at Multiple Spatial Scales
Intense urban and agricultural development alters habitats, increases fragmentation, and may decouple trophic interactions if plants or animals cannot disperse to needed resources. Specialist insects represent a substantial proportion of global biodiversity and their fidelity to discrete microhabitats provides a powerful framework for investigating organismal responses to human land use. We sam...
متن کاملPlant Defences Against Herbivore and Insect Attack
The story of Adam and Eve links eating a forbidden fruit with death in the cycle of human existence (Genesis 3:1– 24). Indeed, to avoid poisoning, herbivores and omnivores such as humans must be cautious in choosing which plants and plant parts to eat. A prevailing hypothesis is that the nearly ubiquitous antiherbivore metabolites in plants were selected by coevolution with herbivores. Likewise...
متن کاملChemical phenotype matching between a plant and its insect herbivore.
Two potential outcomes of a coevolutionary interaction are an escalating arms race and stable cycling. The general expectation has been that arms races predominate in cases of polygenic inheritance of resistance traits and permanent cycling predominates in cases in which resistance is controlled by major genes. In the interaction between Depressaria pastinacella, the parsnip webworm, and Pastin...
متن کاملDifferential effects of land use on ant and herbivore insect communities associated with Caryocar brasiliense (Caryocaraceae).
Simplification of natural habitats leads to a modification of the community associated with a host plant. Pequi trees (Caryocar brasiliense) are common to find in central Brazil, especially in the middle of monocultures, such as soy, corn, pasturelands or Eucalyptus plantations. On this scenario we hypothesized that habitat modification differentially affects the diversity of ants and herbivore...
