Herbivory-induced responses in plants can both negatively affect subsequently colonizing herbivores and mitigate the effect of herbivory on the host. However, it is still less known whether plants exhibit specific responses to specialist and generalist herbivores in non-secondary metabolite traits and how specificity to specialists and generalists differs between invasive and native plant popul...
Many plants and ants engage in mutualisms where plants provide food and shelter to the ants in exchange for protection against herbivores and competitors. Although several species of herbivores thwart ant defenses and extract resources from the plants, the mechanisms that allow these herbivores to avoid attack are poorly understood. The specialist insect herbivore, Piezogaster reclusus (Hemipte...
BACKGROUND Plants are hotbeds for parasites such as arthropod herbivores, which acquire nutrients and energy from their hosts in order to grow and reproduce. Hence plants are selected to evolve resistance, which in turn selects for herbivores that can cope with this resistance. To preserve their fitness when attacked by herbivores, plants can employ complex strategies that include reallocation ...
Linguatula serrata is a tongue-shaped parasite that infects carnivores or insectivorous reptile as final host and herbivores as intermediate ones. During necropsy of a 1.5-year-old female stray cat, a few white and fine nodules were observed on the diaphragmatic lobes of the lung. In histopathological examination, the nodules contained a turned spinosum parasite with cuticular spines and in par...
Release from specialist insect herbivores may allow invasive plants to evolve traits associated with decreased resistance and increased competitive ability. Given that there may be genetic trade-off between resistance and tolerance, invasive plants could also become more tolerant to herbivores. Although it is widely acknowledged that light availability affects tolerance to herbivores, little in...
While understanding feeding preferences of herbivores and carnivores is major importance in ecology, we still know very little on the sensitivity different functional groups to suboptimal stoichiometric resource quality. Here, apply concepts ecological stoichiometry shed light differences nutritional requirements carnivores, make predictions influence quality fitness these consumers to. Herbivo...
