SummaryInteractions between a large community of vertebrate frugivore-granivores (including 7 species of large canopy birds, 19 species of rodents, 7 species of ruminants, and 6 species of monkeys), and 122 fruit species they consume, were studied for a year in a tropical rainforest in Gabon.The results show how morphological characters of fruits are involved in the choice and partitioning of the available fruit spectrum among consumer taxa. Despite an outstanding lack of specificity between… 
Living in the land of ghosts: fruit traits and the importance of large mammals as seed dispersers in the Pantanal, Brazil.
Large-scale comparisons between areas with different faunal assemblages have been widely used to investigate local co-adaptations between plants and frugivores and are a powerful tool in analyses of ecological convergence at the community level.
Interactions between fleshy fruits and frugivores in a tropical seasonal forest in Thailand
To insure the natural seed dispersal process in the Forest, an evaluation of all frugivore groups in the forest is urgently needed in Southeast Asia.
Fruit size in a tropical tree species: variation, preference by birds, and heritability
Based on mother-offspring regressions of mean fruit size, the phenotypic variation in fruit diameter in O. tenera is highly heritable, indicating the potential for an evolutionary response to selection by birds, but directional selection on fruit size or shape is likely to be inconsistent, constrained by genetic correlations, and weak compared to selection on traits like fecundity or phenology.
Fruit Traits in Baboon Diet: A Comparison with Plant Species Characteristics in West Africa
Primate fruit choice among plant species has been attributed to different morphological plant and fruit characteristics. Despite a high abundance of animal‐dispersed plant species in the
Relations between fruits and disperser assemblages in a Malagasy littoral forest: a community-level approach
Frugivores have different impacts on seed dispersal, while frugivorous birds and flying foxes ensure plant regeneration between and outside forest fragments and heterogeneous seed transport is particularly important for this severely degraded littoral forest.
Fruit traits of tree species in lower montane rainforest at Doi Suthep–Pui, northern Thailand
Indicating fleshy fruit can be a food resource for frugivores especially small-sized fruit, large-fruited species such as Madhuca floribunda is low density but important to preserve for food resource of large frugIVores.
Fruit size, crop mass, and plant height explain differential fruit choice of primates and birds
Analysis of the interactions between 81 animal species feeding on the fruits of 30 plant species in Kakamega Forest, Kenya, found significant differences in fruit choice between both groups, and discusses why the observed primate dispersal syndrome is most likely explained by a process of ecological fitting.
Fruit Trait Preference in Rhesus Macaques (Macaca mulatta) and its Implications for Seed Dispersal
It is suggested that further studies be conducted across habitats and time to understand the consistency of interactions between primates and fruits with specific traits to determine the degree of selective pressure (if any) that is exerted by primates on fruit traits.
Primate-Plant Mutualisms: Is There Evidence for Primate Fruit Syndromes?
The primate fruit syndrome hypothesis is reviewed and it is suggested that because of recent technological advances that allow for the quantification of fruit traits, coupled with the importance of primates as seed dispersers and the relative ease with which it is possible to quantify primate seed dispersal relative to other taxa, primates are excellent taxa with which to test the fruit Syndrome hypothesis.
A Multi-Forest Comparison of Dietary Preferences and Seed Dispersal by Ateles spp
Variation in plant community structure strongly influences dietary preferences, and hence, seed dispersal by spider monkeys, and thus, diffuse coevolution in spider monkey-plant relationships may be limited to few taxa at the generic and familial levels.


It is hypothesized that extinction of this plant at this site would lead to disappearance of these birds, and would almost certainly depress recruitment of other species of trees for which they serve as dispersal agents at other times of the year.
This paper compares the removal rates of mid-latitude fruits before, during and after fall bird migrations, analyzes seasonal variation in the ripening patterns of plants in the context of frugivore availability, and provides a theoretical framework for future work on the phenology of temperate fruit/bird interactions.
Inter-relationships between type, size and colour of fruits and dispersal in southern African trees
The indigenous angiosperm tree flora of southern Africa was analysed for type, size and colour of fruits and class of biotic dispersal agent (consumer), and green as a cryptic colour is incompatible with the demonstrated mammalian selection of this colour.
Interactions between birds and fruit in a temperate woodland
It is concluded that other factors such as palatability or content of other nutrients may be important in determining the feeding preferences of different species of frugivorous birds.
Wide geographical ranges of this tree and members of the frugivore assemblage, use of other food resources by common foragers, richness of the assemblages, variation in species visitation at individual trees, irregular annual fruit production, and obvious "inefficiency" of the dominant dispersal agents from the perspective of the plant suggest that Tetragastris has a generalized dispersal strategy.
Frugivorous Bats, Seed Shadows, and the Structure of Tropical Forests
The general factors that influence plant distribution patterns are discussed and it is concluded that seedling establishment probabilities are concordant with seed-deposition probabilities, at least in smallseeded, bat-dispersed colonizing plant species.
Relationships between Fruiting Seasons and Seed Dispersal Methods in a Neotropical Forest
The weight of fruits and seeds that fell into 75 polyethylene sheets, each 152 x 152 cm, totalling 175 m2 in area, was measured over a period of 17 months in the humid forest of Barro Colorado Island, in the Panama Canal Zone, to study the determinants of fruiting times.
Seasonal Variation in the Quality of Fruits and Diffuse Coevolution Between Plants and Avian Dispersers
The significance of highly rewarding winter fruits for the evolution of some physiological and behavioral traits among overwintering dispersers points to the existence of a closely coevolved system involving the latter and the assemblage of winter-ripening mediterranean evergreens.

It is hypothesized that temperate-zone species would "choose," evolutionarily; animal food over Fruit during the breeding season and that this has resulted in negative selection pressure on plants to produce fruit during the temperates-zone avian breeding season.
Fruit variation and competition for dispersers in natural populations of Smilax aspera
Multiple stepwise regression analysis shows that the best single predictor of the mean number of seeds per fruit is the number of plant species bearing fruits simultaneously and equally or more abundant than S. aspera, suggesting that observed variation in fruit seed numbers must be attributed to interspecific competition for dispersers among plants.
