“…3) es la mayor de las observadas hasta ahora en las comunidades autónomas peninsulares, solo superada por las de la cornisa cantábrica (País Vasco y Asturias) y, por supuesto, por los archipiélagos. Estos últimos datos ponen de manifiesto, una vez más, la mayor capacidad de acogida de especies de plantas vasculares alóctonas que presentan las zonas costeras e insulares con respecto a las continentales (Sobrino et al 2002;Sanz Elorza et al 2006).…”

Continuando con la serie de trabajos en los que vamos dando a conocer la flora alóctona de diversas comunidades autónomas del estado español, como han sido los casos de Castilla y León (Sanz Elorza et al. 2008) y de Aragón (Sanz Elorza et al. 2009), abordamos en esta ocasión el estado de la cuestión en la Comunidad Valenciana. A pesar de que hoy en día se dispone de una cantidad de información relativa a las especies exóticas en nuestro país impensable hace apenas unos años, la escasa difusión de la misma sigue pesando como uno de los aspectos más limitantes para las labores tanto del científico como del gestor ambiental. Esta falta de disponibilidad de la informa-ción da lugar que el número de especies invasoras tienda a ser significativamente subestimado (McGeoch et al. 2010). Por tanto, el primer objetivo de este trabajo es compilar toda la información dispersa que existe sobre la presencia de especies de plantas vasculares exóticas en el territorio valenciano, para después abordar su análisis desde variados puntos de vista, tales como la evolución histórica del proceso de introducción de flora alóctona, su incidencia en las diferentes provincias de la comunidad autónoma, los principales atributos de las especies introducidas (taxonomía, origen biogeográfico, tipos biológicos, estatus), la situación en la que se encuentra la Comunidad Valenciana en comparación con otras comunidades autónomas y territorios próximos y el alcance y la suficiencia de 97

“…On the other hand, human activities such as forestry, agriculture and urbanization often compete for space with riparian forests leading to their degradation (Pennington, Hansel & Gorchov, 2010). Additionally, because human activities are the primary cause of the introduction (intentional or accidental) of alien species, the proximity of these activities to riparian forests increases their exposure to biological invasions (Sanz-Elorza, Dana & Sobrino, 2006;Giorgis et al, 2011;Spear et al, 2013).…”

Invasion of temperate deciduous broadleaf forests by N‐fixing tree species – consequences for stream ecosystems

et al. 2021

View full text Add to dashboard Cite

Biological invasions are a major threat to biodiversity and ecosystem functioning. Forest invasion by alien woody species can have cross-ecosystem effects. This is especially relevant in the case of stream-riparian forest meta-ecosystems as forest streams depend strongly on riparian vegetation for carbon, nutrients and energy. Forest invasion by woody species with dissimilar characteristics from native species may be particularly troublesome. The invasion of temperate deciduous broadleaf forests with low representation of nitrogen (N)-fixing species by N-fixers has the potential to induce ecosystem changes at the stream level. Although effects of tree invasion on stream ecosystems have been under assessed, knowledge of native and invasive tree characteristics allows prediction of invasion effects on streams. Here we present a conceptual model to predict the review of the literature addressing effects of increasing cover of N-fixing species on streams suggests a wide application of the model, while it highlights the need to consider differences in the type of system and species when making generalizations. Changes induced by N-fixing species invasion on streams can jeopardize multiple ecosystem services (e.g. good quality water, hydroelectricity, leisure activities), with relevant social and economic consequences.

“…The richness of alien weeds in fruit-tree orchards was higher (29.5% of all weed species) than the average richness of alien weeds in other regions in the east and northeast of the Iberian Peninsula (i.e. Huesca and Comunidad Valenciana), where the alien flora does not exceed 20% of the total flora (Sanz-Elorza et al, 2006. The richness of alien weeds in the fruit-tree orchards in our study was higher than the richness of alien weeds in other agroecosystems in Catalonia (7.3% in the arable lands and 2.6% in wet grasslands of Catalonia; Chytrý et al, 2008) and in other regions (e.g.…”

In addition to their impact on natural habitats, invasive alien plants can have a significant negative effect on agricultural systems and cause economic losses. Flood-irrigated orchards in the Mediterranean Basin are vulnerable to the invasion of alien weeds, primarily because of the traditional management practices used in the orchards, which are characterized by high soil moisture during the dry summer period, nutrient availability and high levels of disturbance. This study sought to determine whether their biological traits can explain the success of alien weed species. To answer this question, 408 floristic relevés were conducted in 136 flood-irrigated orchards on the Plains of Lleida (Catalonia, NE of Spain). Richness and cover of native and alien weeds were compared. Furthermore, a set of biological traits were compared between successful and non-successful weeds for the whole data and separately between native and alien weeds using logistic regression and classification trees. In floodirrigated orchards, alien species covered most of their area, even though the richness of alien species was lower than that of the native species. The most important species were C4 species with seeds dispersed by water, and on the other hand, rosulate and caespitose-reptant hemicryptophytes with long flowering period. Most of these traits fitted with those of the invasive alien weeds, which were mostly C4 species with seeds dispersed by water. Perennial life form characterized successful native weeds. In this study, we discuss how the traditional management of flood irrigation in fruit-tree orchards favours invasive alien weeds that have specific traits, acting as a reservoir for the spread of alien weeds into other crops and surrounding riparian habitats. We also propose changing management practices in order to avoid the selection of alien weeds and to promote native species.
