Megjegyzések:	Background and Aims Many plant species undergo long-distance dispersal through migratory waterbirds. However, there is little information about the effectiveness of this dispersal, especially regarding the chances of plant establishment and the impact of gut passage or the faecal matrix on plant germination, growth and reproductive investment in seeds. ? Methods In a greenhouse experiment, we addressed these questions using an annual mudflat species, Juncus bufonius (Juncaceae), and a perennial emergent aquatic species, Eleocharis palustris (Cyperaceae), whose seeds are dispersed by many waterbird species in Europe. We planted seeds directly in soil or within mallard faeces placed on soil, using both control seeds and seeds that survived gut passage through mallards. Over the following 11 weeks, we quantified germination and plant performance. ? Key Results Gut passage reduced germination time of J. bufonius when there was no faecal matrix, and it increased asymptotic height of E. palustris. Presence of the faecal matrix hindered germinability, plant growth and final biomass for both species, along with total seed production for J. bufonius. Presence of the faecal matrix slowed down germination in E. palustris, but had the opposite effect for J. bufonius. It was also associated with greater relative investment in seeds in J. bufonius (more seeds per unit biomass), probably as a consequence of later germination. In both species, earlier germination increased final biomass (and seed production in J. bufonius). ? Conclusions Our results support the importance of waterbird endozoochory in plant dispersal but suggest that it might be more effective when faeces disintegrate, such as when egested into water or disaggregated on land (e.g. by insects). Previous studies with other plants have recorded accelerated germination following waterbird gut passage, and our results show that this can benefit plant fitness.

Megjegyzések:	The dispersal of fish into distant and isolated habitats remains a topic of continuous discussion in the field of fish biogeography. This is particularly relevant due to the perceived limitation of fish movement to what is known as active dispersal. Fish migration is often confined to interconnected water bodies, underscoring the significance of dispersal for fish inhabiting isolated aquatic habitats. However, empirical evidence for a natural (i.e. not human-mediated) mechanism has been limited. Here we explore and provide evidence for waterbird-mediated endozoochory as a possible dispersal mechanism in various fish species and families. We force-fed mallards Anas plathyrynchos with fertilised eggs of nine bony fish species, covering nine taxonomic families. We recovered viable embryos of five fish taxa in the faeces of mallard, proving the ability of fish eggs to survive the passing of the digestive system of waterbirds. Moreover, the recovered eggs successfully hatched into larvae in two fish species. Taking into the flight speed and numerosity of mallards, as well as the high abundance of fish eggs, our results highlight endozoochory of fish eggs by waterbirds as a possible significant, although likely rare natural dispersal mechanism that can occur across more species than previously known in freshwater fish.

Cím:	Putative 'Dispersal Adaptations' Do Not Explain the Colonisation of a Volcanic Island by Vascular Plants, but Birds Can / Pawel Wasowicz, Ádám Lovas-Kiss, Nándor Szabó, Andy J. Green

Megjegyzések:	Dispersal syndromes based on traits assumed to be adaptations for specific dispersal mechanisms are routinely assigned to flow-ering plants. Using the colonisation record from a volcanic island formed in 1963, we assess whether dispersal syndromes predictwhich species establish on newly formed land. We evaluated the long-distance dispersal (LDD) syndromes of the 78 plant speciesusing three European classification systems. Syndrome assignments were inconsistent between classifications (coinciding for? 13% of species). Two systems showed no evidence that LDD syndromes conferred a colonisation advantage. The third classi-fication suggested wind syndromes were favoured, but only assigned a minority of colonisers to LDD syndromes. ♭Unassisted'species assumed to lack dispersal adaptations were dominant. However, empirical evidence supports endozoochory via aquaticbirds for 62 colonisers. This suggests bird-dispersal is a major driver of colonisation for dry-fruited plants, and underscores theneed for new approaches to plant dispersal that account for overlooked plant?animal interactions
