Seed dispersal facilitation among plant neighbours can be defined as an increase in the number, distances, and/or places reached by a plant's seeds that is due to the presence of co-fruiting plant neighbours with which it shares seed dispersers. Many cases of this phenomenon have been described among native species and some also among introduced invasive species. Moreover, facilitation of native species recruitment by non-native fleshy-fruiting trees has been reported. Surprisingly, seed dispersal facilitation of exotic species by native species is either less common or has not been properly documented so far. Casual observation of secondary vegetation in La Araucanía Region, Chile, suggests that more individuals of exotic fleshy-fruiting bird-dispersed Rubus praecox (Rosaceae) are established under the native fleshy fruiting bird-dispersed subdioecious tree Aristotelia chilensis (Elaeocarpaceae) than under other native dry-fruiting tree species in the same areas. To assess whether these observation-suggested differences are statistically significant, two plots were sampled for interspecific associations between Rubus and Aristotelia and between Rubus and the most common dry-fruiting monoecious tree -Lomatia hirsuta (Proteaceae). The first important conclusion from this study is that invasive Rubus is substantially more common under both focal tree species than in open grasslands. Second, Rubus is associated more strongly with fleshy-fruiting Aristotelia than with dry-fruiting Lomatia in this landscape. Additionally, the frequency of Rubus is higher under Aristotelia fruiting (female or hermaphroditic) trees. Management implications are discussed.Keywords: Frugivory, plant invasion, seed dispersal, South-Central Chile. RESUMENLa facilitación de la dispersión de las semillas entre plantas vecinas se puede definir como un incremento en el número, distancia, y/o lugares alcanzados por las semillas de una planta debido a la presencia de plantas vecinas que co-fructifican y con las que la especie comparte dispersores de semillas. Se han descrito muchos casos de este fenómeno entre especies nativas y algunas también entre especies introducidas invasoras. Además, se ha informado de la facilitación del reclutamiento de especies nativas por árboles no-nativos de fruto carnoso. Sorprendentemente, la facilitación de la dispersión de semillas de las especies exóticas por especies nativas es menos común, o no ha sido debidamente documentada hasta el momento. La observación casual de la vegetación secundaria en la Región de la Araucanía, Chile, sugiere que más individuos de la especie exótica Rubus praecox (Rosaceae), cuyos frutos carnosos son dispersados por las aves, se establecen bajo el árbol nativo Aristotelia chilensis (Elaeocarpaceae) que también posee frutos carnosos, que bajo otra especies de árboles nativos con frutos secos en las mismas áreas. Para evaluar si las diferencias de observación sugeridas son estadísticamente significativas, se muestrearon dos parcelas para estudiar las asociaciones interespecífi...

“…The germination of fruit-dispersed seed is often increased once the seeds have passed through the digestive tract of birds (Norconk et al 1998;Gosper et al 2005;CalvinoCancela et al 2006). Frugivorous birds are well recognized as important seed dispersers, particularly in rainforests (Traveset 1998;Gosper et al 2005;Neilan et al 2006), but these birds are also important dispersal agents for several Mediterranean plants/weeds (e.g. bridal creeper (Stansbury 2001); mistletoe (Amyema quandang) (Murphy et al 1993); Lantana camara (Gosper et al 2005)).…”

“…Vertebrates are often important dispersal agents, spreading seed by endozoochorous (via digestive tract) or exozoochorous (adhesion to animals) means (Calvino-Cancela et al 2006). In particular, the role of frugivorous birds in the dispersal of seed contained within fleshy fruits is well recognized in tropical (Stansbury & VivianSmith 2003;Moran et al 2004;Gosper et al 2005;Neilan et al 2006) and non-tropical (Stansbury 2001;Calvino-Cancela 2004;Garcia et al 2005;Milton et al 2007;Ward & Paton 2007;Wotton et al 2008) environments. However, the ability of seed-eating birds (hereafter refers to both obligate seedeaters and seed-eating omnivores) to spread viable seed is less understood.…”

The potential of seed‐eating birds to spread viable seeds of weeds and other undesirable plants

The potential for seed-eating birds to spread viable seeds was investigated using captive-feeding trials to determine seed preference, passage time through the gut, and viability of passed seeds for bronzewing pigeons (Phaps chalcoptera), peaceful doves (Geopelia striata), crested pigeons suggesting that these bird species may potentially disperse seed over moderate distances. Despite the low probability of individual birds spreading viable seed, the high number of birds feeding in the wild suggests that the potential for granivorous and seed-eating omnivorous birds to disperse viable seeds cannot be discounted, particularly if exozoochorous dispersal is also considered.

“…Second, birds can spread seed to isolated natural areas in which it can be difficult to locate and manage the invasion (Murphy et al 2008;Westcott et al 2008). Third, bird-dispersed weeds may provide benefits to native fauna through the provision of food and habitat (Date et al 1991;Gosper and Vivian-Smith 2006), and to native flora by acting as pioneers and providing a suitable environment for seedling establishment (Neilan et al 2006;Rodriguez 2006). Consequently, management of these species is often both complex and contentious.…”

“…Manipulation of such processes is complicated by the potential impacts of management strategies on native species; any action that affects dispersal of invasive species (e.g. perch sites construction) is likely to also impact native flora or fauna (Neilan et al 2006;White et al 2006). Furthermore, manipulating dispersal processes will only be successful if a species is dispersallimited such as in the early stages of invasion.…”

Invasive bird-dispersed plants often share the same suite of dispersers as co-occurring native species, resulting in a complex management issue. Integrated management strategies could incorporate manipulation of dispersal or establishment processes. To improve our understanding of these processes, we quantified seed rain, recruit and seed bank density, and species richness for bird-dispersed invasive and native species in three early successional subtropical habitats in eastern Australia: tree regrowth, shrub regrowth and native restoration plantings. We investigated the effects of environmental factors (leaf area index (LAI), distance to edge, herbaceous ground cover and distance to nearest neighbour) on seed rain, seed bank and recruit abundance. Propagule availability was not always a good predictor of recruitment. For instance, although native tree seed rain density was similar, and species richness was higher, in native plantings, compared with tree regrowth, recruit density and species richness were lower. Native plantings also received lower densities of invasive tree seed rain than did tree regrowth habitats, but supported a similar density of invasive tree recruits. Invasive shrub seed rain was recorded in highest densities in shrub regrowth sites, but recruit density was similar between habitats. We discuss the role of microsite characteristics in influencing postdispersal processes and recruit composition, and suggest ways of manipulating these processes as part of an integrated management strategy for birddispersed weeds in natural areas.
