Lema Márquez, MargaritaVieites Blanco, Cristina2018-12-102018-12-102018http://hdl.handle.net/10347/17913The invasive plant Carpobrotus edulis can alter soil properties through its necromass (chemically different from natives’). Depending on the accumulated necromass, C. edulis has contrasting effects on soil pH, leading to different effects on nutrient availability. Carpobrotus edulis alters the soil nitrogen cycle through changes in nitrogen fluxes that can limit nitrogen availability. Until now, potential agents for biocontrol of C. edulis had not been studied. The fungus Sclerotinia sclerotiorum can infect C. edulis, but with no long‐term consequences in greenhouse conditions. The insect Pulvinariella mesembryanthemi can reduce survival and growth of the plant. This insect was introduced accidentally in NW Spain, where its potential distribution roughly overlaps that of C. edulis, but its abundance may be restricted by weather conditions in winter, parasitism and predation. Worldwide introductions of P. mesembryanthemi seem to originate from one native population, and most of its genetic variability resides in its native area.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Ciclo do nitróxenoSclerotinia sclerotiorumPulvinariella mesembryanthemiMaterias::Investigación::25 Ciencias de la tierra y del espacio::2511 Ciencias del suelo (Edafología)::251101 Bioquímica de suelosMaterias::Investigación::24 Ciencias de la vida::2417 Biología vegetal (botánica)::241799 Plantas invasorasdoctoral thesisopen access
