Resumo: Large mammalian herbivores (i.e. ungulates) induce changes in the chemistry, physiology, distribution and abundance of the plants they feed on. Plant-dwelling arthropods (PDI), predominantly insect herbivores, as well as the predators and parasitoids that inhabit the plants are also affected. Such plant-mediated indirect interaction between mammals and PDI has been extensively studied. However, mammalian herbivores may also directly affect PDI by incidentally ingesting them while feeding (incidental predation). Because of their ubiquity and small size, PDI are highly vulnerable to incidental ingestion by ungulates that consume large amounts of plant material. As common as this interaction may intuitively seem, very little is known about its prevalence, importance and ecological implications (trophic cascades). In the seminar, ill share with you different angels of these direct interactions in various habitats and animal communities.
