Data from: Masting increases seedling recruitment near and far: predator satiation and improved dispersal in a fleshy-fruited tree
<p><span>The animal dispersal hypothesis predicts that mast seeding can increase dispersal rate of seeds by dispersers and enhance reproductive success of plants. However, in contrast to pollination efficiency and predator satiation hypothesis, the animal dispersal hypothesis has received mixed support. </span></p> <p><span>Using 12-year data on fruit production and seedling recruitment of a fleshy-fruited tree rowan (<em>Sorbus aucuparia</em>, Rosaceae), we tested if an increase in the fruit production at the population level results in higher proportion of fruits recruiting into seedlings. Recruitment was recorded near (under rowans) and far (under heterospecifics) from conspecifics. Higher recruitment rates under rowans would support predator satiation hypothesis. Higher recruitment rates under heterospecific trees, where fruits can only arrive with animal assistance, would support animal dispersal hypothesis.</span></p> <p><span>High population-level fruit production increased the proportion of fruits recruiting into seedlings both near and far from rowans. In contrast, high individual-level fruit production did not have a positive effect on the proportion of fruits recruiting into seedlings. </span></p> <p><span>Synthesis. Population-level synchronization of fruit production is required to generate a more effective plant regeneration. Our findings show that masting enhances seedling recruitment through predator satiation and increased seed dispersal by frugivores. The results provide support for both animal dispersal and predator satiation hypotheses indicating that both mechanisms can operate simultaneously.</span></p>

Data from: Angiosperm fleshy fruits and seed dispersers: a comparative analysis of adaptation and constraints in plant-animal interactions
Variation in phenotypic traits of angiosperm fleshy fruits has been explained as the result of adaptations to their mutualistic seed dispersers. By analyzing the information available on fleshy fruit characteristics of 910 angiosperm species, I assess the hypothesis of evolutionary association between fruit phenotypic traits and type of seed disperser (birds, mammals, and mixed dispersers) and address explicitly and quantitatively alternative null hypotheses about phylogenetic effects. Phylogenetic affinity among plant taxa is accounted for by comparative methods including nested ANOVA, phylogenetic autocorrelation, and independent contrasts. Averaging over the 16 fruit traits examined, phylogenetic effects down to genus level explain 61% of total variance. Phylogenetic autocorrelations are strong among close relatives, reaching significance for 11 of the 16 fruit traits examined. When assessed by independent contrast methods, correlated evolution between type of disperser and fruit traits is confined to fruit diameter. Differences among dispersal syndromes in other traits vanish after accounting for phylogenetic effects. These analyses reveal that seed dispersal syndromes are not entirely interpretable as current adaptations to seed dispersers. Their status as exaptations can be assessed by combining experimental studies of natural selection on fruit size and rigorous comparative and cladistic tests of adaptational hypotheses.
Data from: Water and fish select for fleshy fruits in tropical wetland forests
Adjacent floodplain and upland tropical forests experience the same temperature and precipitation regimes, but differ substantially in plant species composition and biotic interactions because of extensive flooding. We hypothesize that flooded forests filter fruiting traits linked to seed dispersal by water and fishes, such that selection by water and fish led to (1) trees that synchronize the timing of fruiting with annual floods, and (2) the evolution of fleshy tissues on fruits to improve buoyancy and increase fruit consumption rates by fish. To test this hypothesis, we compared plant communities in seasonally flooded forests and adjacent upland forest in terms of fruiting phenology, the frequency of trees bearing fleshy-fruit, and the role of fleshy tissues in buoyancy and seed viability. Beta-diversity in this system is high, with significant differences in species composition across habitats. As predicted, the production of ripe fleshy fruits was significantly greater in flooded than upland forests during the flood season. Furthermore, we found that trees with fleshy fruit were significantly more abundant in flooded forests even though species richness of fleshy-fruit bearing trees was proportionally similar in flooded and upland forests. Additionally, fleshy pulp increased buoyancy. Likewise, time afloat decreased for denser fruit and those with high seed to pulp ratios. In concert, these results suggest that fleshy fruits in Neotropical floodplain forests facilitated hydrochory and ichthyochory. Once established, water and fish became important agents of selection on fruiting traits.
Data from: Colour, design, and reward: phenotypic integration of fleshy fruit displays
The functional or structural linkage among traits (phenotypic integration; PI) within complex structures can constrain the evolutionary response of individual traits. To analyse whether frugivores with distinct sensory ecology have shaped the patterns of fruit diversification differently, we compared PI values of fleshy fruits that are consumed by birds and mammals. We used phylogenetic comparative analyses of PI among 13 morphological, nutritional and visual fruit traits from 111 Mediterranean plant species. Results showed that morphological traits had higher PI values than nutritional and colour traits. Visual and nutritional traits show positive phylogenetic covariance, while negative covariation occurs between fruits size and nutrients. Importantly, fruits consumed by birds were relatively more integrated than fruits consumed partly or solely by mammals. Hence we show that major groups of mutualistic frugivores can shape the covariance among some fruit traits differently and thereby influence fruit diversification.
Data from: From ratites to rats: the size of fleshy fruits shapes species' distributions and continental rainforest assembly
Seed dispersal is a key process in plant spatial dynamics. However, consistently applicable generalisations about dispersal across scales are mostly absent because of the constraints on measuring propagule dispersal distances for many species. Here, we focus on fleshy-fruited taxa, specifically taxa with large fleshy fruits and their dispersers across an entire continental rainforest biome. We compare species-level results of whole-chloroplast DNA analyses in sister taxa with large and small fruits, to regional plot-based samples (310 plots), and whole of continent patterns for the distribution of woody species with either large (>30mm) or smaller fleshy fruits (1093 taxa). The pairwise genomic comparison found higher genetic distances between populations and between regions in the large-fruited species (Endiandra globosa), but higher overall diversity within the small-fruited species (Endiandra discolor). Floristic comparisons among plots confirmed lower numbers of large-fruited species in areas where more extreme rainforest contraction occurred, and re-colonisation by small-fruited species readily dispersed by the available fauna. Species distribution patterns showed that larger-fruited species had smaller geographic ranges than smaller-fruited species and locations with stable refugia (and high endemism) aligned with concentrations of large fleshy-fruited taxa, making them a potentially valuable conservation-planning indicator.

Effect of the common palm civet's gut passage on seed germination of fleshy fruits in Pachmarhi Wildlife Sanctuary, Central India
<p>Frugivorous carnivores like civets consume fruits of many species and play an important role in their seed dispersal by virtue of depositing their scats farther away from the parent tree. This study was conducted to understand the role of the common palm civet in affecting the seed germination rate of three plant species (i.e., <em>Syzygium cumini, Phoenix sylvestris, and Ficus racemosa</em>) in a tropical moist deciduous forest. We collected scats of common palm civets in Pachmarhi Wildlife Sanctuary, Central India, and monitored the germination rate of these species for 90 days. Further, to understand the patters of seed selection (if there are any), for seeds of a specific size, we compared the length, width, and mass of the civet-ingested seeds with those of the control seeds. We had to discard the analyses on<em> F. racemosa</em> as none of its seeds in any treatment group germinated even after 50 days. Our results show a differential impact of gut passage: civet-ingested <em>P. sylvestris</em> seeds experienced a higher germination percentage compared to the control seeds, whilst gut passage did not alter the seed germination of<em> S. cumini</em>. However, seed germination speed (proportion of seeds germinated per day) for both species, <em>P. sylvestris </em>and <em>S. cumini</em>, was faster for civet-ingested seeds compared to their respective controls. Our findings also show that civets preferred seeds that were lesser in length and width and weighed lesser in the case of <em>P. sylvestris</em>, however, no such statistically significant difference was found for seed selection in the case of <em>S. cumini</em>. Thus, our study shows that civets act as a legitimate seed disperser of plant species and exert a differential impact on altering the germination rate.</p>
