Roth on dunes or sandy soil communities (Soukupova 1992;Bakker and Berendse 1999), and the recent invasion of European salt marshes by Elymus athericus (Link) Kerguélen along the coasts of the North Sea, English Channel and Atlantic Ocean (Van Wijnen et al 1997;Bockelmann and Neuhaus 1999;Valéry et al 2004). This long list of examples unfortunately shows how frequent native invasions are.…”

Biodiversity is currently undermined worldwide principally as a result of human activities. The irreversibility of species extinction has encouraged the research community to investigate the potential effect of declining species or functional group diversity and/or composition on ecosystem function since the beginning of the 1990s. However, while changes in relative abundance among species (i.e., evenness) are more frequent than extinction of species and are able to cause important changes in ecosystem function, most studies have curiously not examined thoroughly the potential role of that diversity component. The few small-scale experimental manipulations that have so far examined the relationship between evenness and ecosystem function have produced ambiguous results, sometimes indicating an effect on selected functions, and sometimes not. Because one reason for the inconsistency of the previous results may be scale-dependency issues, we propose here an alternative approach, investigation of this relationship directly at the system-level through the opportunity offered by field studies of ecosystemlevel consequences of invasions by native species. Indeed, the specificities of changes in ecosystem structure induced by native invaders compared to exotic ones could constitute a useful tool to improve our understanding of the relationship between evenness and ecosystem function as well as to evaluate the importance of the spatial arrangement of species in the stability of ecosystems.

“…In intertidal salt marshes, regular tidal flooding (bimonthly) is controlled by natural processes, but habitat structure has been modified by the introduction of an invasive grass species (Valéry et al 2004). Both flooding and the modification of the vegetation architecture may lead to an adjustment of flood-avoiding and resistance strategies, respectively (Foster 2000).…”

“…Our study concerned one single species yet, and deleterious effects of Elymus athericus invasions have been documented on both saltmarsh biodiversity (e.g. Bos et al 2002;Bouchard et al 2003) and functioning (Valéry et al 2004;Laffaille et al 2005). Further experiments should also include other dominant species, as ground-living spiders can oppositely react to changes in habitat structure (Pétillon et al 2005b).…”

“…Although these activities have been considered to have low environmental impact, Pérez-Negrón and Casas (2007) suggested that, in some communities, cactus fruit collection can total 151 kg/year and wood extraction for fuel can be more than 400 tons/year. Therefore, these activities have the potential to shift species diversity and composition resulting in direct species loss (Osem et al, 2002) or favoring the establishment of invasive species, either exotic or native (Valéry et al, 2004;Blaum et al, 2007) that could be used as indicator species.…”

Antecedentes y Objetivos: La fragmentación del hábitat y otras alteraciones humanas pueden causar la pérdida de fertilidad del suelo, erosión y la pérdida de biodiversidad, entre otras; sin embargo, la información en zonas áridas es limitada. El objetivo de este trabajo fue determinar los efectos de un gradiente de disturbio en la composición de especies en dos tipos de vegetación en un ecosistema semi-árido del centro de México.Métodos: Se seleccionaron seis zonas de estudio diferentes en la zona de Cerro Colorado, tres de matorral xerófilo y tres de bosque tropical caducifolio. Se determinó la diversidad genérica y específica utilizando 10 cuadrantes (un total de 60), localizados al azar, durante los meses de mayo-junio de 2011. Se generó un índice de perturbación basado en las actividades que se registraron en la región como pastoreo y tala, entre otros. Las áreas de alto, medio y bajo disturbio se identificaron en el matorral xerófilo y bosque tropical caducifolio.Resultados clave: Los resultados mostraron que el bosque tropical caducifolio es más diverso que el matorral xerófilo, además de que es posible utilizar a los arbustos Cnidoscolus tehuacanensis y Mimosa luisana como indicadores, ya que se encontraban en lugares con altos niveles de perturbación. Por otro lado, en el bosque tropical caducifolio, tres géneros (Thevetia, Acacia y Bursera) presentan altas abundancias relativas en lugares conservados, mientras que en el matorral xerófilo solo uno (Parkinsonia) tiene este patrón.Conclusiones: De los resultados se puede inferir que en hábitats semiáridos del Centro de México las actividades antropogénicas juegan un papel importante en la diversidad florística, ya que facilitan el establecimiento de algunas plantas nativas que pueden ser consideradas como colonizadoras. Estas pueden ser utilizadas como indicadoras de los disturbios con la finalidad de determinar la viabilidad de hábitat para otros taxa.
