“…The release from specialized herbivores could also result in the selection for an increased competitive ability in alien plants (Evolution of Increased Competitive Ability hypothesis; Nö tzold 1995, Callaway andRidenour 2004) with positive effects on seed production. However, exotic species can also acquire new enemies that negatively impact seed production and/or seed mortality (Vanhellemont et al 2014). Indirect interactions, such as apparent competition, may provide invasive plant species with a competitive advantage over native species .…”

Abstract. Indirect interactions occur when the effect of one species on another is mediated by a third species. These interactions occur in most multi-species assemblages and are diverse in their mechanistic pathways. The interest in indirect interactions has increased exponentially over the past three decades, in recognition of their importance in determining plant community dynamics and promoting species coexistence. Here, we review the literature on indirect interactions among plants published since 1990, using a novel synthetic framework that accounts for and classifies intervening species and mechanisms within trophic networks. The objectives of this review are: (1) to identify the geographical regions and ecosystem types where indirect interactions have been examined; (2) to summarize the information on the number of trophic levels examined in studies of indirect interactions; (3) to test whether the frequency of indirect interactions varies across environmental gradients; and (4) to identify the experimental approaches most commonly used in studies of indirect interactions. Studies examining indirect interactions in plants have been conducted primarily in the Northern Hemisphere, with a focus on grasslands and forests. The majority of studies (67%) examined two trophic levels. Indirect facilitation and apparent competition are the interactions that have been most frequently examined, with the latter being reported more frequently in relatively productive environments. Other indirect interactions reported include associational resistance, exploitative competition or facilitation, shared defenses, and trophic cascades. Generally, field experiments tested indirect interactions based on single target species. While the majority of studies on indirect interactions dealt with basic ecology issues, several studies have dealt with such interactions in the context of biological invasions (18%) and rangeland management (12%). This review allowed us identifying a number of research needs, including the study of non-feeding interactions and that for more realistic complex designs, explicitly testing indirect interactions across different trophic levels, in geographical regions that have been under-examined to date, and in stressful ecosystems.

“…It is possible that a lower seed predation might contribute to denser seeds banks in many woody species in their new ranges. However, some species might acquire new enemies in the new range (Vanhellemont et al 2014), with potential negative effects on seed bank density (Hulme 1998;Krushelnycky 2014;Pearson et al 2014).…”

Characteristics of the soil seed bank of invasive and non-invasive plants in their native and alien distribution range

The ability to form persistent seed banks might contribute substantially to determine the invasion potential of alien plants in their new distribution ranges, given the role of seed banks as sources of propagules, genetic diversity, and in spreading the risk of germination failure over time. Using the largest seed bank dataset collated to date, comprising 14,293 records for 2566 species, we examined whether the type (transient vs persistent) and density of the seed banks of invasive species differ in their native (home) and alien (abroad) range, and whether these attributes differ among invasive and non-invasive congeners, at home and abroad. A lower probability of forming a persistent seed bank in the alien range was identified when analyzing data for 140 invasive species, although phylogenetic analyses run for 104 of those species did not confirm such differences. However, invasive woody species formed denser seed banks in the alien range, suggesting greater seed production and/or lower seed predation or mortality in the alien than native range. Interestingly, invasive species consistently showed a higher probability of forming persistent seed banks as well as denser seed banks than their non-invasive congeners in their native range, but not in their alien range. These findings provide the first quantitative evidence, based on a large number of species globally, of preadaptation with respect to species life-history traits resulting in the formation of a persistent seed bank in invasive species compared to their non-invasive congeners. The fact that both invasive and non-invasive congeners have similar probabilities of forming persistent seed banks abroad suggests that this might be an important attribute for the establishment of alien species in new ranges (naturalization phase), but not for their spread (invasion phase). Our findings also indicate that the characteristics of native seed banks should be an important component of risk assessments aimed at identifying species that are more likely to become invasive if introduced in new ranges.

“…Leather (Leather, 1985) reported, however, that P. padus did not host a large variety of species of herbivorous insects, finding instead that out of 196 species of herbivores feeding on seven species in the genus Prunus in the UK, only 23 of those species were associated with P. padus. Not only folivorous insects include P. serotina in their food base; for example, seeds of P. padus and P. serotina grown in Belgium were damaged by an insect that typically feeds on seeds, the weevil Furcipus rectirostris Linnaeus (Vanhellemont et al, 2014). Based on a meta-analysis, Leimu and Koricheva (Leimu & Koricheva, 2006) suggested that if a plant is susceptible to feeding by generalist insects, it will be used by many species, not only one.…”

“…Moreover, the intended introduction of black cherry (Prunus serotina Ehrh. ), and the negative consequences resulting from its expansiveness (Vanhellemont et al, 2009), has caused interest in the use of this alien species by native European herbivores (Karolewski et al, 2014(Karolewski et al, , 2017Vanhellemont et al, 2014;Mąderek et al, 2015). An additional cause for undertaking such research has been an attempt to explain the extremely high level of leaf damage caused by folivores of P. padus (Leather, 1986;Leather & Mackenzie, 1994;Alonso, 1999), as well as on P. serotina growing in the shade -much greater damage than observed for other species of understory shrubs (Karolewski et al, 2013).…”

The quality of leaves as food for insects is affected both by plant species and the light conditions present during growth. Little information exists concerning the impact of these factors on the diversity of insects that live in the forest understory. We studied arthropod fauna on six understory plant species commonly occurring in Europe. Different groups of herbivorous insects were identified, as well as predatory insects and arachnids. We analysed the influence of both plant species and light conditions during growth (low light; high light) on the species spectrum, and the number of insect specimens present. The resulting data were investigated in relation to the susceptibility of plant leaves to feeding by folivorous insects, as determined in earlier studies. We compared the similarity in species diversity, based on the Sørensen’s coefficient, and discussed the potential causes of observed differences in leaf damages. We found a total of 153 arthropod taxa on studied plants, under both light conditions. Corylus avellana and Prunus serotina, species characterized by greater leaf damage, have a wider diversity of arthropod species, and a greater number of herbivorous insects. Generally, light conditions had a greater effect on arthropod abundance than on species diversity. For two plant species, C. avellana and P. serotina, light conditions strongly, but reversely, influenced the total number of insects and, thus, the extent of leaf damage. The number and abundance of zoophagous species, and ratio to folivores (except C. avellana) are associated more with plant species than with light conditions
