“…Short-distance dispersal can be favoured by several other vertebrates such as cattle, rats, rabbits, amphibians and fish (e.g. Zedler & Black, 1992;Bohonak & Whiteman, 1999;Beladjal et al, 2007;Van Leeuwen et al, 2013 and literature therein) as well as by invertebrates (Duthie, 1929); in particular, crayfish (Pérez-Bote et al, 2005) and flying insects (van de Meutter et al, 2008;Beladjal & Mertens, 2009) are documented vectors for the dispersal of resting stages and seeds among temporary waters, and water mites are known to be phoretic on insect larvae and adults (Di Sabatino et al, 2004;Bohonak et al, 2004).…”

“…Five months after the creation of the mesocosms, most plant species established from the seed bank of the control mesocosms. Aquatic plants may establish from the seed bank (Leck, 2003;De Steven et al, 2006) but also by seed deposition through water dispersal (Mitsch et al, 1998), waterbirds (Brochet et al, 2010;, vertebrates (Zedler and Black, 1992), or wind dispersal (Reinartz and Warne, 1993). However, these mechanisms of colonization are not efficient, because dispersal is slow and sometimes unlikely (Moreno-Mateos and Comin, 2010).…”

“…If the appropriate environmental conditions, mainly consisting of flooding regimes, water depth, and salinity, are restored (Grillas, 1990), vegetation can rapidly establish from the residual seed bank (Leck, 2003;De Steven et al, 2006). Short distance dispersal (Reinartz and Warne, 1993), long distance endozoochorous (Brochet et al, 2010;Zedler and Black, 1992), and ectozoochorous dispersal may also contribute to spontaneous colonization Active revegetation methods may not be needed if sources populations of desired seeds are available nearby and if physical barriers do not hamper dispersal (Moreno-Mateos and Comin, 2010). Vegetation recovery is often limited by a low density and a high distance of seed sources (Bischoff, 2002).…”

Key-words:former ricefield, restoration, spontaneous colonization, soil transfer, temporary wetland Mediterranean temporary wetlands have considerably declined in recent decades. Today, opportunities arise for the restoration of these wetlands due to land-use changes, such as the abandonment of cultivation. One critical question is whether communities, such as those observed in natural temporary wetlands, can develop alone or if active restoration should be implemented. In a series of experimental mesocosms, we transferred soil from several temporary wetlands chosen as a set of reference ecosystems. Four months after soil transfer, vegetation in transfer mesocosms was compared to that derived from spontaneous colonization (control mesocoms). Transfer mesocosms are colonized by all target hydrophyte species transferred with the soil and the resulting communities are similar to those of reference ecosystems. They also have fewer non-target species than the control mesocosms. Even though the study period was not sufficient to draw any definitive conclusion regarding the utility of forced dispersion by soil transfer, the preliminary results are promising for an application on a larger scale. RÉSUMÉRestauration d'un milieu humide temporaire après culture du riz : le transfert de sol est-il nécessaire à la recolonisation des plantes aquatiques ? Mots-clés :anciennes rizières, restauration, colonisation spontanée, transfert de sol, zone humide Les marais temporaires méditerranéens ont vu leur superficie se réduire considé-rablement au cours des dernières décennies. Aujourd'hui, des opportunités apparaissent pour la restauration de ces zones humides, en particulier à partir d'espaces agricoles abandonnés. L'une des questions majeures est alors de savoir si les communautés telles que l'on peut les observer dans les marais temporaires naturels peuvent se développer seules ou si une restauration active doit être mise en place. Dans un ensemble de mésocosmes expérimentaux, nous avons transféré du sol provenant de plusieurs marais temporaires choisis comme un ensemble d'écosystèmes de référence. Quatre mois après le transfert de sol, la végétation des mésocosmes transférés a été comparée à celle issue uniquement de la colonisation spontanée (témoins). Les mésocosmes ayant subi un transfert de sol sont colonisés par la totalité des hydrophytes cibles transférées par le sol et présentent des communautés similaires à celles des écosystèmes de référence. Ils présentent d'autre part moins d'espèces jugées indésirables que les mésocosmes témoins. Même si la durée de l'étude ne nous permet pas de conclure définitivement sur la nécessité d'opérer un forçage de dispersion par transfert de sol, ces résultats préliminaires sont prometteurs pour une application à plus large échelle.

In Canada, Dwarf Woolly-heads, Psilocarphus brevissimus var. brevissimus, is restricted to the Similkameen River valley, south of Princeton in southwestern British Columbia and the extreme southeast and southwest corners of Alberta and Saskatchewan, respectively. This paper deals with the three British Columbia populations which represent the northwestern limit of the species which ranges from south-central British Columbia, southward in the western United States to Montana, Idaho, Washington, Oregon, Nevada, Utah, Wyoming, California and Baja California, Mexico. In British Columbia, P. brevissimus is associated with calcareous vernal pools and ephemeral pond edges in large forest openings. This habitat is rare in the area the few existing populations could easily be extirpated or degraded through slight changes in groundwater levels, coalbed methane gas drilling, housing development or recreational vehicles.
