“…D. viscosa has very high coverage percentages in riparian plant communities in SE Spain, that have undergone major alterations and have been seriously degraded as a result of anthropic effects (Salinas et al, 2000 ); in a recent study, it has been also reported as the most frequent species on roadsides in Portugal (Simões et al, 2013 ). Its capability to colonize new habitats and threaten the biodiversity has been well documented (Wacquant, 1990 ) and was related to characteristics such as its phenotypic plasticity (Wacquant and Bouab, 1983 ), high stress tolerance (Curadi et al, 2005 ), and resistance to chemical pollution (Murciego et al, 2007 ; Fernández et al, 2013 ), as well as to its allelopathic effects (Omezzine et al, 2011 ). In the last 50 years, D. viscosa has become an invader in the NW Mediterranean region, since it increased its ecological range under disturbance pressure and is colonizing new habitats (Wacquant, 1990 ; Boonne et al, 1992 ; Wacquant and Baus Picard, 1992 ; Mateo et al, 2013 ).…”

Native-Invasive Plants vs. Halophytes in Mediterranean Salt Marshes: Stress Tolerance Mechanisms in Two Related Species

Dittrichia viscosa is a Mediterranean ruderal species that over the last decades has expanded into new habitats, including coastal salt marshes, ecosystems that are per se fragile and threatened by human activities. To assess the potential risk that this native-invasive species represents for the genuine salt marsh vegetation, we compared its distribution with that of Inula crithmoides, a taxonomically related halophyte, in three salt marshes located in “La Albufera” Natural Park, near the city of Valencia (East Spain). The presence of D. viscosa was restricted to areas of low and moderate salinity, while I. crithmoides was also present in the most saline zones of the salt marshes. Analyses of the responses of the two species to salt and water stress treatments in controlled experiments revealed that both activate the same physiological stress tolerance mechanisms, based essentially on the transport of toxic ions to the leaves—where they are presumably compartmentalized in vacuoles—and the accumulation of specific osmolytes for osmotic adjustment. The two species differ in the efficiency of those mechanisms: salt-induced increases in Na+ and Cl− contents were higher in I. crithmoides than in D. viscosa, and the osmolytes (especially glycine betaine, but also arabinose, fructose and glucose) accumulated at higher levels in the former species. This explains the (slightly) higher stress tolerance of I. crithmoides, as compared to D. viscosa, established from growth inhibition measurements and their distribution in nature. The possible activation of K+ transport to the leaves under high salinity conditions may also contribute to salt tolerance in I. crithmoides. Oxidative stress level—estimated from malondialdehyde accumulation—was higher in the less tolerant D. viscosa, which consequently activated antioxidant responses as a defense mechanism against stress; these responses were weaker or absent in the more tolerant I. crithmoides. Based on these results, we concluded that although D. viscosa cannot directly compete with true halophytes in highly saline environments, it is nevertheless quite stress tolerant and therefore represents a threat for the vegetation located on the salt marshes borders, where several endemic and threatened species are found in the area of study.

“…One is by seeds which can be collected at the end of October, the second is through cuttings, and the third is the transplantation of whole plants. Although in nature germinates the following year without interventions, the germination rates in the pots are poor [36]. The impact of salinity on the germination rate of D. viscosa in Slovenia was studied by Grašič et al [38].…”

Dittrichia viscosa: Native-Non Native Invader

Dittrichia viscosa (L.) Greuter is a shrub native to the Mediterranean, however, declared as a very invasive species in Australia and North America. Environmental (climatic) and socio-economic (land abandonment) changes can trigger different adaptive mechanisms and cause changes in species behavior, influencing invasion dynamics. Motivated by the recently noticed change of D. viscosa behavior in its native Mediterranean habitat, we discuss the invasion properties, its behavior in the native habitat and new areas, and its management options. We review the species’ adverse effects and its positive ecosystem services in the Millennium Ecosystem Assessment framework. In this review, we provide information on the phytochemical properties of D. viscosa and highlight its potential use in ecological agriculture, phytopharmacy, and medicine. The presented data is useful for developing effective management of this contentious species, with emphasis on mitigating environmental and economic damages, especially in agriculture. The final aim is to achieve a balanced ecosystem, providing a high level of possible services (provisioning, regulating, cultural and supporting).
