9 p, 1.7 MB Paper dels insectes en l'èxit d'invasió de Senecio inaequidens i S. pterophorus al Parc Natural del Montseny / Castells, Eva (Universitat Autònoma de Barcelona. Departament de Farmacologia, de Terapèutica i de Toxicologia) ; Morante, Maria ; Escolà, Anna
Les espècies d'origen sud-africà Senecio inaequidens i Senecio pterophorus envaeixen diferents hàbitats del Parc Natural del Montseny. L'establiment de noves interaccions amb els herbívors locals pot afectar negativament l'èxit d'invasió de les espècies exòtiques. [...]

71.9 KB Contemporary evolution of an invasive plant is associated with climate but not with herbivory. / Castells, Eva (Universitat Autònoma de Barcelona. Departament de Farmacologia, de Terapèutica i de Toxicologia) ; Colomer Ventura, Ferran (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Martínez Vilalta, Jordi, 1975- (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Zuccarini, Paolo (Institut de Recerca i Tecnologia Agroalimentàries (IRTA)) ; Escolà, Anna (Universitat Autònoma de Barcelona. Departament de Farmacologia, de Terapèutica i de Toxicologia) ; Armengot, Laura (Universitat de Barcelona. Departament de Biologia Vegetal)
Divergence in plant traits and trait plasticity after invasion has been proposed as mechanisms favouring invasion success. Current hypotheses predict a rapid evolution in response to changes in the abiotic conditions in the area of introduction or to differences in the herbivore consumption pressure caused by a decrease in the enemies associated with the area of origin [e. [...]

36 p, 229.4 KB Diversity of pyrrolizidine alkaloids in native and invasive Senecio pterophorus (Asteraceae) : Implications for toxicity / Castells, Eva (Universitat Autònoma de Barcelona. Departament de Farmacologia, de Terapèutica i de Toxicologia) ; Mulder, Patrick P.J. ; Pérez Trujillo, Míriam (Universitat Autònoma de Barcelona. Servei de Ressonància Magnètica Nuclear)
Changes in plant chemical defenses after invasion could have consequences on the invaded ecosystems by modifying the interactions between plants and herbivores and facilitating invasion success. However, no comprehensive biogeographical studies have yet determined the phenotypic levels of plant chemical defenses, as consumed by local herbivores, covering large distributional areas of a species.

33 p, 314.5 KB Herbivores on native and exotic Senecio plants : is host switching related to plant novelty and insect diet breadth under field conditions? / Castells, Eva (Universitat Autònoma de Barcelona.

Departament de Farmacologia, de Terapèutica i de Toxicologia) ; Goula, Marta (Universitat Autònoma de Barcelona. Departament de Biologia Animal) ; Pérez, Nicolás ; Dantart, Jordi ; Escolà, Anna (Universitat Autònoma de Barcelona. Departament de Farmacologia, de Terapèutica i de Toxicologia)
1. Native herbivores can establish novel interactions with alien plants after invasion. Nevertheless, it is unclear whether these new associations are quantitatively significant compared to the assemblages with native flora under natural conditions. [...]

34 p, 312.2 KB Reduced seed predation after invasion supports enemy release in a broad biogeographical survey / Castells, Eva (Universitat Autònoma de Barcelona. Departament de Farmacologia, de Terapèutica i de Toxicologia) ; Morante, Maria (Universitat Autònoma de Barcelona. Departament de Farmacologia, de Terapèutica i de Toxicologia) ; Blanco-Moreno, José M. (Universitat Autònoma de Barcelona. Departament de Biologia Vegetal) ; Sans, F. Xavier (Universitat Autònoma de Barcelona. Departament de Biologia Vegetal) ; Vilatersana, Roser (Institut Botànic de Barcelona) ; Blasco-Moreno, Annabel (Universitat Autònoma de Barcelona. Servei d'Estadística Aplicada)
The Enemy Release (ER) hypothesis predicts an increase in the plant invasive capacity after being released from their associated herbivores or pathogens in their area of origin. Despite the large number of studies on biological invasions addressing this hypothesis, tests evaluating changes in herbivory on native and introduced populations and their effects on plant reproductive potential at a biogeographical level are relatively rare.

34 p, 168.9 KB Geographical variation in alkaloid production in Conium maculatum populations experiencing differential herbivory by Agonopterix alstroemeriana / Castells, Eva (Universitat Autònoma de Barcelona. Departament de Farmacologia, de Terapèutica i de Toxicologia) ; Berhow, M.A. ; Vaughn, S.F. ; Berenbaum, M.R.
Conium maculatum, a Eurasian weed naturalized in North America, contains high concentrations of piperidine alkaloids, which act as chemical defenses against herbivores. In the United States, C. maculatum was largely free from herbivory until approximately 30 years ago, when it was re-associated via accidental introduction with a monophagous European herbivore, the oecophorid caterpillar Agonopterix alstroemeriana.

9 p, 285.6 KB Laboratory rearing of Agonopterix alstroemeriana, the defoliating poison hemlock (Conium maculatum L.) moth, and effects of piperidine alkaloids on preference and performance. / Castells, Eva (Universitat Autònoma de Barcelona. Departament de Farmacologia, de Terapèutica i de Toxicologia) ; Berenbaum, May R.
Conium maculatum L. (Apiaceae), or poison hemlock, is an invasive plant native to Europe that has become extensively naturalized throughout North America. This species contains piperidine alkaloids, including coniine and -coniceine, that are highly toxic to vertebrates. [...]

30 p, 171.5 KB Resistance of the generalist moth Trichoplusia ni (Noctuidae) to a novel chemical defense in the invasive plant Conium maculatum / Castells, Eva (Universitat Autònoma de Barcelona. Departament de Farmacologia, de Terapèutica i de Toxicologia) ; Berenbaum, M.R.
Conium maculatum is an apiaceous species native to Eurasia that is highly toxic to vertebrates due to the presence of piperidine alkaloids, including coniine and γ-coniceine. More than 200 years after invading the United States this species remains mostly free from generalist insect herbivores. [...]

32 p, 155.9 KB Host plant selection by a monophagous herbivore is not mediated by quantitative changes in unique plant chemistry : Agonopterix alstroemeriana and Conium maculatum / Castells, Eva (Universitat Autònoma de Barcelona. Departament de Farmacologia, de Terapèutica i de Toxicologia) ; Berenbaum, M.R.
Host plant selection by ovipositing females is a key process determining the success of phytophagous insects. In oligophagous lepidopterans, host-specific plant secondary chemicals are expected to be dominant factors governing oviposition behavior; distinctive compounds can serve as high-contrast signals that clearly differentiate confamilial hosts from non-hosts increasing the accuracy of host quality evaluation.
