Seed Dispersal by Fall Migrant Frugivorous Birds in an East-Central Illinois Woodland (Treefall Gap)
I investigated patterns of seedfall, avian frugivore pre- and post-foraging behavior, and seed germination and seedling success for several species of bird-dispersed plants in an east-central Illinois deciduous woodland. Using seed traps and a combination of natural and artificial fruit displays, I …

Frugivoria e dispersão de sementes por Chiroxiphia pareola (pipridae) em um brejo de altitude, nordeste do Brasil
… and predators attacks next the mother plant. The frugivorous birds are considered seed dispersor efficients because the seed amount and transported distance. Manakins (Pipridae) are good exemples of seed dispersors birds. We evaluated the relationship between Chiroxiphia pareola distribution and …

Host-Parasitoid Interactions of Two Invasive Drosophilids in Virginia Fruit Crops
… traps were used to survey for parasitoids of frugivorous drosophilids in Virginia fruit cropping systems, and determine if parasitoids were attacking invasive flies Drosophila suzukii (Matsumura) and Zaprionus indianus Gupta (Diptera: Drosophilidae) in the field. Two parasitoids of frugivorous …

Genetics and Reproductive Isolation of Rhagoletis Flies (Fruit Fly, Eclosion, Speciation, Electrophoresis, Host Selection)
The frugivorous flies of the Rhagoletis pomonella (Diptera: Tephritidae) species group have been cited as examples of sympatric speciation through divergence in host plant association. Despite the attention given to and the controversy engendered by the biology of these flies, both by applied …

Biotic and abiotic mechanisms shaping multi-species interactions
… niche partitioning of Piper fruits among three frugivorous bats, illustrating the importance of fine-scale mechanisms that facilitate species coexistence and influence plant–animal interactions. In Chapter 3, I demonstrate how the chemical ecology of a Neotropical shrub, Piper sancti-felicis, …

Frugivory and North American Migrants in a Neotropical Second-Growth Woodland
… the fruit less when dominants were abundant. Frugivorous migrants increase in abundance in late spring, due to migration, and they outnumber non-migrants in their representation at fruit sources.

Avian ecology and rapid morphological change in a novel plant-frugivore system
… the rapid morphological change of the main frugivorous birds on the Hawaiian Island of Oʻahu where all native frugivores have gone extinct. To understand how the morphological changes may influence the species’ ecology, I then related their foraging and movement behavior to their morphology. …

Wax Myrtle and Myrtle Warblers: Reciprocal Specialization and its Consequences in a Temperate Fruit-Frugivore Interaction
Interactions between fruiting plant and frugivorous species are considered to be highly generalized, resulting in diffuse mutualisms. Specialization has frequently been found to be either asymmetrical or the result of restricted options for frugivores. This dissertation documents a highly unusual …

Patterns of neotropical Chiropteran reproduction including historlogical and ecological aspects of bats collected in Belize
… All but one of these species, D. rotundus, were frugivorous. An additional 90 bats of 7 species were collected at various roostsites, two caves, a fig tree, and the farmhouse. All but one of these bat species were insectivorous. The exception was G. soricina, a frugivorous species, which was the …

The Use of Fallback Foods in a Population of Black Handed Spider Monkeys at Runaway Creek Nature Reserve, Belize
… consequences, in a population of highly frugivorous spider monkeys. Spider monkeys have previously been suggested to fall back on leaves, however I found that flowers, not leaves, were used as a fallback food. Seasonal reliance on flowers led to decreases in time spent travelling and …

Seed dispersal of western and Utah junipers: the role of scatter-hoarding rodents.
… those produced by Utah juniper, J. osteosperma. Frugivorous birds and mammals have been found to disperse some juniper species through endozoochory by consuming juniper cones and passing intact seeds in their feces. However, seed dispersal in many other juniper species is not fully understood. …

Espaço ecomorfológico da fauna de quirópteros da região do Alto Tocantins, GO: uma perspectiva através da análise da morfologia alar
… is characterized by small insectivores and frugivorous with high ar moderate wing loading. Forest formations (gallery forests and dry forests) seem to play a crucial role in the definition of the bat assemblage features. Such habitat types represent mesic conditions contrasting with the open …

Seed dispersal in South African trees: with a focus on the megafaunal fruit and their dispersal agents
… not the case; in South America where the largest frugivorous mammal is the tapir (300kg; Hansen and Galetti, 2009), there is a subset of fruit that are conspicuously large. The paradoxical existence of such large fruit in the lowlands of Costa Rica was first noted by Janzen. In collaboration with …

Uakaris and Amazonian flooded forest.
… floodplains of Amazonian Rivers. It is the only frugivorous primate able to live within the young $\textbf{varzeas}$ (white-water river floodplain) of the Amazon. A 20-month study of the ecology of the white uakaris $\textbf{(Cacajao calvus calvus)}$ was carried out in the floodplain located …

Manipulating social information to promote frugivory by birds on a Hawaiian island
… been introduced to the island many of which are frugivorous. Yet, introduced birds may not recognize native fruits as a resource and social information may be needed for introduced frugivores to target and feed on native fruits. We investigated if social information, in the form of broadcasted …

Nonrandom seed dispersal by lemur frugivores: mechanism, patterns and impacts
… experiments, focusing on seed dispersal by three frugivorous lemur species in the biodiverse rainforest of Ranomafana National Park, Madagascar. An analysis of traits suggested that 84% of trees in Ranomafana are adapted for animal dispersal, of which more than 70% are dispersed by these three …

Fruits and frugivory in neotropical primates and in Amazonian flooded and unflooded forests

The Ecology and Evolution of the Folivore Gut Microbiome in Madagascar’s Lemurs
… across folivorous sifakas (Propithecus spp.) and frugivorous brown lemurs (Eulemur spp.). These lineages diverged over similar evolutionary time and live sympatrically in Madagascar’s rainforests and dry forests. Next, I compared GMBs across sympatric species of sifaka (P. diadema), indri (Indri …
