“…It is likely that the heavy reliance of Alouatta species on leaves, and their energetically conservative lifestyle (Nagy and Milton, 1979;Strier, 1992), could explain this pattern. Similarly, Cebus olivaceus do not need to track changes in fruit supply because it frequently rely on arthropods, an energy-rich and widely available food, and exhibits a widely flexible diet, expanding their dietary breadth when preferred foods are not available (Gómez-Posada, 2012;Terborgh, 1983). Exploiting alternating food resources is a means of escaping seasonal fruit shortages (van Schaik et al, 1993).…”

Few attempts have been made to understand how spatiotemporal changes in fruit supply influence frugivores in tropical forests. The marked spatiotemporal variation in fruit supply can affect frugivore abundance and distribution, but studies addressing the effects of this variation on primates are scarce. The present study aimed to investigate how the spatiotemporal distribution of fruits influences the local distribution of three frugivorous primates in the eastern part of the Maracá Ecological Station, a highly seasonal Amazonian rainforest. Specifically, it was hypothesised that primate distribution will track changes in fruit supply, resulting that sites with high fruit availability should be heavily used by primates. During a 1-year study, fruit supply (ground fruit surveys) and primate density (line-transects) were monitored in twelve 2 km-long transects at monthly intervals. Fruit supply varied seasonally, being low during the dry season. The density of Ateles belzebuth was positively related to fruit supply during fruit shortage, but Cebus olivaceus and Alouatta macconnelli did not follow the same pattern. The supply of Sapotaceae fruit was an important component determining local distribution of A. belzebuth during the overall fruit shortage. Highly frugivorous primates such as A. belzebuth respond to seasonal decline in fruit supply by congregating at places with high fruit supply in this forest, particularly, those with many individuals of species of Sapotaceae. This study underscores the importance of small-scale spatiotemporal changes of fruit supply as a key component of frugivorous primate ecology in highly seasonal environments.Keywords: Amazonia, Maracá Ecological Station, primate distribution, seasonal fruit availability, fruit shortage. Resposta dos primatas frugívoros à variação na oferta de frutos em uma floresta do norte da Amazônia ResumoPoucas tentativas foram realizadas para entender como a variação espaço-temporal na oferta de frutos influencia os frugívoros nas florestas tropicais. A variação espaço-temporal dos frutos pode afetar a abundância e distribuição dos frugívoros, mas estudos abordando os efeitos desta variação nos primatas são escassos. Neste estudo, investigou-se como a oferta dos frutos afeta a distribuição local de três espécies de primatas frugívoros na parte leste da Estação Ecológica de Maracá, uma floresta sazonal na Amazônia. Especificamente, testou-se a hipótese de que a distribuição dos primatas acompanharia a variação na oferta de frutos, resultando em uma utilização mais frequente pelos primatas dos locais com maior disponibilidade deste recurso. A disponibilidade de frutos e a densidade dos primatas foram registradas mensalmente ao longo de um ano, em 12 transecções com 2 km de extensão. A oferta de frutos variou sazonalmente, sendo baixa durante a estação seca. A densidade de Ateles belzebuth se relacionou com a oferta dos frutos durante o período de escassez deste recurso, mas Alouatta macconnelli e Cebus olivaceus não seguiram o mesmo padrão. A oferta d...

“…Embora esperada, a exploração de artrópodes em teias de aranha por exemplares de C. albifrons não havia sido registrada, ainda mais estando estas em uma estrutura construída pelo homem (passarela suspensa). Sabe-se que a abundância e a composição de artrópodes em florestas tropicais podem sofrer drásticas mudanças provocadas pela sazonalidade, implicando em mudanças nas táticas de obtenção por parte de seus predadores (Rímoli et al, 2008;Gómez-Posada, 2012). Na Amazônia colombiana, S. apella foi observado buscando artrópodes principalmente em folhas enroladas e dentro de troncos mortos.…”

Primatas do gênero Cebus têm notável destreza manual, alta sociabilidade e dieta onívora. Essas habilidades permitem que explorem os recursos alimentares de maneira própria e muitas vezes mais eficaz que outros primatas. Aqui nós apresentamos as estratégias alimentares de um grupo de cairaras (Cebus albifrons) em uma área protegida no Baixo Rio Negro, Amazonas. O método ad libitum foi usado para a observação de indivíduos que foram vistos se alimentando de sementes de girassol (Helianthus annuus) e abóbora (Cucurbita moschata), examinando teias de aranhas em busca de invertebrados, e quebrando ouriços de castanha do Brasil (Bertholletia excelsa) para acessar as amêndoas. O comportamento dos animais observados indica elaboradas estratégias para acesso ao alimento em um ambiente altamente sazonal, onde a disponibilidade de recursos é influenciada pelas chuvas e pelo nível do Rio Negro.

“…In P. cecropiifolia , humans selected for fruits with larger sizes and larger masses than those found in wild populations, in which large fruits are not favored by natural selection ( McCouch, 2004 ). Dispersers of wild P. cecropiifolia in the forest are usually small-sized primates, such as Saguinus mystax, S. fuscicollis ( Knogge and Heymann, 2003 ), Callimico goeldii, Saguinus labiatus ( Porter, 2001 ) and Cebus apella ( Gómez-Posada, 2012 ). Smaller fruits may provide an advantage over large fruits for dispersal by small-sized primates, because they can be more easily removed, transported and dispersed ( Tanksley, 2004 ).…”

The Domestication of the Amazon Tree Grape (Pourouma cecropiifolia) Under an Ecological Lens

Domestication studies traditionally focus on the differences in morphological characteristics between wild and domesticated populations that are under direct selection, the components of the domestication syndrome. Here, we consider that other aspects can be modified, because of the interdependence between plant characteristics and the forces of natural selection. We investigated the ongoing domestication of Pourouma cecropiifolia populations cultivated by the Ticuna people in Western Amazonia, using traditional and ecological approaches. We compared fruit characteristics between wild and domesticated populations to quantify the direct effects of domestication. To examine the characteristics that are not under direct selection and the correlated effects of human selection and natural selection, we investigated the differences in vegetative characteristics, changes in seed:fruit allometric relations and the relations of these characteristics with variation in environmental conditions summarized in a principal component analysis. Domestication generated great changes in fruit characteristics, as expected in fruit crops. The fruits of domesticated plants had 20× greater mass and twice as much edible pulp as wild fruits. The plant height:DBH ratio and wood density were, respectively, 42% and 22% smaller in domesticated populations, probably in response to greater luminosity and higher sand content of the cultivated landscapes. Seed:fruit allometry was modified by domestication: although domesticated plants have heavier seeds, the domesticated fruits have proportionally (46%) smaller seed mass compared to wild fruits. The high light availability and poor soils of cultivated landscapes may have contributed to seed mass reduction, while human selection promoted seed mass increase in correlation with fruit mass increase. These contrasting effects generated a proportionately smaller increase in seed mass in domesticated plants. In this study, it was not possible to clearly dissociate the environmental effects from the domestication effects in changes in morphological characteristics, because the environmental conditions were intensively modified by human management, showing that plant domestication is intrinsically related to landscape domestication. Our results suggest that evaluation of environmental conditions together with human selection on domesticated phenotypes provide a better understanding of the changes generated by domestication in plants.
