Complementary Effects of Species Abundances and Ecological Neighborhood on the Occurrence of Fruit-Frugivore Interactions

Abstract: Species interactions are traditionally seen as the outcome of both ecological and evolutionary mechanisms. Among them, the two most frequently studied are the neutral role of species abundances in determining encounter probability and the deterministic role of species identity (traits and evolutionary history) in determining the compatibility of interacting species. Nevertheless, the occurrence of pairwise interactions also depends on the spatio-temporal context imposed by the ecological neighborhood (i.e., th… Show more

“…On the other hand, frugivore biodiversity effects varied across components of seed dispersal, which may be partly associated with the occurrence of complex interactions between frugivore abundance and diversity (e.g., stronger effects of diversity at small abundances, Rumeu et al, ), though the present data do not facilitate testing this (but see Rodríguez‐Pérez, García, Martínez, & Morales, ). Even so, our results showed positive effects of diversity irrespective of abundance, probably related to sampling effects (the incorporation of functionally dominant frugivores, Schleuning et al, ), spatial complementarity (with a greater diversity meaning a higher variety of spatial behaviours after fruit consumption; Morales, García, Martínez, Rodríguez‐Pérez, & Herrera, ) or even interspecific interactions (with a greater diversity leading to facilitation in, e.g., fruit resource tracking; Donoso, García, Martínez, Tylianakis, & Stouffer, ).…”

“…Our results suggest that the number of fruit removed is the principal fitness component, at least at this reproductive stage. From the plant's perspective, fruit production should be maximized at the limit of the costs of fruit production to guarantee seed dispersal in a competitive scenario for seed dispersers (Howe and Estabrook, 1977;Albrecht et al, 2015;Donoso et al, 2017). It is worth mentioning that a greater dispersal success (absolute and relative) does not necessarily entails greater recruiting success, due to uncoupling between successive recruitment stages (Jordano and Herrera, 1995;Wang and Smith, 2002;Palacio et al, 2014; but see Blendinger et al, 2011).…”

“…This suggests that there are interannual fluctuations in the frequency of interactions that may result from changes in relative fruit availability, for example due to variations in plant phenology constraining seed dispersers' preferences (Carlo & Morales, 2008;Donoso, García, Martínez, Tylianakis, & Stouffer, 2017;Rumeu et al, 2019).…”
