“…In the absence of long-term data on the diet of most Neotropical primates, it remains unclear whether high proportions reported in some studies represent a general pattern or an exceptional year or period. For instance, in moustached tamarins, Saguinus mystax , rates of predation on frogs were generally very low, but in 1 year showed a 5–10-fold increase during a 3-month period (Lüffe et al 2018 ). The lack of more long-term data also leaves the apparent positive correlation of the proportion of ants in the diet with body mass in cebids and negative correlation in pitheciids as a preliminary finding that needs to be verified or rejected with more data.…”

Ants are the dominant group of animals in many habitats, particularly in tropical rainforests. High abundance and formation of large colonies convert them into a potential food source for a broad spectrum of animals. In this paper we review myrmecovory (consumption of ants) in Neotropical primates. Myrmecovory has been reported from 57 taxa (species + subspecies) out of 217 species of Neotropical primates, representing 18 out of 22 genera. The proportion of ants in the animal portion of the diet is highest amongst members of the genera Cebus, Sapajus, Cheracebus and Plecturocebus, but generally low in callitrichids, large pitheciids (Cacajao, Chiropotes) and atelids. Ants from seven subfamilies of Formicidae (out of 13 subfamilies found in the Neotropics) are consumed, including taxa with and without functional sting and with varying other defences. Foraging technics employed in myrmecovory range from picking ants from open substrates to extractive foraging involving the destruction of ant nests or shelters, but tool use has not been reported. We conclude that myrmecovory is widespread amongst Neotropical primates but on average contributes only a minor proportion of the diet. The diversity of foraging technics employed and lack of tool use in Neotropical primate myrmecovory, even for ants with functional stings and aggressive biting, suggests that tool use for myrmecovory in hominids has not evolved in response to ant defences but is a consequence of enhanced cognitive skills that evolved under other selection pressures.

Vertically stratified frugivore community composition and interaction frequency in a liana fruiting across forest strata

Vertical stratification is a key feature of tropical forests and structures plant-frugivore interactions. However, it is unclear whether vertical differences in plant-frugivore interactions are due to differences among strata in plant community composition or inherent preferences of frugivores for specific strata. To test this, we observed fruit removal of a diverse frugivore community on the liana Marcgravia longifolia in a Peruvian rain forest. Unlike most other plants, Marcgravia longifolia produces fruits across forest strata. This enabled us to study effects of vertical stratification on fruit

PremiseVertical stratification is a key feature of tropical forests and plant–frugivore interactions. However, it is unclear whether equally strong patterns of vertical stratification exist for plant–nectarivore interactions and, if so, which factors drive these patterns. Further, nectar‐inhabiting bacteria, acting as “hidden players” in plant–nectarivore interactions, might be vertically stratified, either in response to differences among strata in microenvironmental conditions or to the nectarivore community serving as vectors.MethodsWe observed visitations by a diverse nectarivore community to the liana Marcgravia longifolia in a Peruvian rainforest and characterized diversity and community composition of nectar‐inhabiting bacteria. Unlike most other plants, M. longifolia produces inflorescences across forest strata, enabling us to study effects of vertical stratification on plant–nectarivore interactions without confounding effects of plant species and stratum.ResultsA significantly higher number of visits were by nectarivorous bats and hummingbirds in the midstory than in the understory and canopy, and the visits were strongly correlated to flower availability and nectar quantity and quality. Trochiline hummingbirds foraged across all strata, whereas hermits remained in the lower strata. The Shannon diversity index for nectar‐inhabiting bacterial communities was highest in the midstory.ConclusionsOur findings suggest that vertical niche differentiation in plant–nectarivore interactions seems to be partly driven by resource abundance, but other factors such as species‐specific preferences of hummingbirds, likely caused by competition, play an important role. We conclude that vertical stratification is an important driver of a species’ interaction niche highlighting its role for promoting biodiversity and ecosystem functioning.
