“…The new leaves production in the dry season can serve as a food source for wildlife. In another forest fragment in the same region, during the dry season (lower supply of fruit), increased consumption of F. eximia young leaves by Alouatta clamitans (Cabrera, 1940) (Santos et al, 2013). Milton (1991) observed that the average time interval between figs crop in F. insipida was higher than that observed to F. adhatodifolia in this study, and this time interval was smaller for larger individuals.…”

“…In this period occur the peak of zoochorous fruit production in the region (Novaes, 2006) and, according to Peres (2000), a resource can be completely replaceable if it is produced during the peak production of other resources. However, in other forest remnant in the region, the selectivity of brown howler monkey (Alouatta clamitans) was mainly directed to species capable of providing fruits along the year, prioritizing these species even when other fruit sources are available (Santos et al, 2013). Three Ficus species (F. adhatodifolia, F. eximia and F. citrifolia) were among the species selected by A. clamitans.…”

We analyzed the phenology of Ficus adhatodifolia Schott ex Spreng. (23 fig tree) and F. eximia Schott (12 fig tree) for 74 months in a remnant of seasonal semi-deciduous forest (23°27'S and 51°15'W), Southern Brazil and discussed their importance to frugivorous. Leaf drop, leaf flush, syconia production and dispersal were recorded. These phenophases occurred year-round, but seasonal peaks were recorded in both leaf phenophases for F. eximia and leaf flushing for F. adhatodifolia. Climatic variables analyzed were positively correlated with reproductive phenophases of F. adhatodifolia and negatively correlated with the vegetative phenophases of F. eximia. In despite of environmental seasonality, little seasonality in the phenology of two species was observed, especially in the reproductive phenology. Both species were important to frugivorous, but F. adhatodifolia can play a relevant role in the remnant. Keywords

Changes in the life cycle of organisms (i.e. phenology) are one of the most widely used early-warning indicators of climate change, yet this remains poorly understood throughout the tropics. We exhaustively reviewed any published and unpublished study on fruiting phenology carried out at the community level in the American tropics and subtropics (latitudinal range: 26°N–26°S) to (1) provide a comprehensive overview of the current status of fruiting phenology research throughout the Neotropics; (2) unravel the climatic factors that have been widely reported as drivers of fruiting phenology; and (3) provide a preliminary assessment of the potential phenological responses of plants under future climatic scenarios. Despite the large number of phenological datasets uncovered (218), our review shows that their geographic distribution is very uneven and insufficient for the large surface of the Neotropics (~ 1 dataset per ~ 78,000 km2). Phenological research is concentrated in few areas with many studies (state of São Paulo, Brazil, and Costa Rica), whereas vast regions elsewhere entirely unstudied. Sampling effort in fruiting phenology studies was generally low: the majority of datasets targeted fewer than 100 plant species (71%), lasted 2 years or less (72%), and only 10.4% monitored > 15 individuals per species. We uncovered only 10 sites with ten or more years of phenological monitoring. The ratio of numbers of species sampled to overall estimates of plant species richness was wholly insufficient for highly diverse vegetation types such as tropical rainforests, seasonal forest and cerrado, and only slightly more robust for less diverse vegetation types, such as deserts, arid shrublands and open grassy savannas. Most plausible drivers of phenology extracted from these datasets were environmental (78.5%), whereas biotic drivers were rare (6%). Among climatic factors, rainfall was explicitly included in 73.4% of cases, followed by air temperature (19.3%). Other environmental cues such as water level (6%), solar radiation or photoperiod (3.2%), and ENSO events (1.4%) were rarely addressed. In addition, drivers were analyzed statistically in only 38% of datasets and techniques were basically correlative, with only 4.8% of studies including any consideration of the inherently autocorrelated character of phenological time series. Fruiting peaks were significantly more often reported during the rainy season both in rainforests and cerrado woodlands, which is at odds with the relatively aseasonal character of the former vegetation type. Given that climatic models predict harsh future conditions for the tropics, we urgently need to determine the magnitude of changes in plant reproductive phenology and distinguish those from cyclical oscillations. Long-term monitoring and herbarium data are therefore key for detecting these trends. Our review shows that the unevenness in geographic distribution of studies, and diversity of sampling methods, vegetation types, and research motivation hinder the emergence of clear general phenolo...

“…Os frutos maduros são característicos, lembram um mamão de menor tamanho com coloração amarela e sabor adocicado e podem ser utilizados na fabricação de doces e compotas (PROSPERO, 2010). Na natureza, o fruto é um dos principais alimentos do primata bugio-ruivo, que também dispersa as sementes entre os meses de fevereiro e março, quando os frutos estão maduros (SANTOS et al, 2013). Os frutos verdes produzem látex com ação proteolítica semelhante ao da papaína.…”

RESUMO -Este trabalho teve por objetivo avaliar a influência de diferentes períodos de sombreamento/ sol em mudas de jaracatiá utilizando parâmetros de qualidade. Foram realizadas três avaliações aos 100, 120, 140 dias após a emergência (DAE), sendo os tratamentos 60, 80, 100 DAE (avaliação 1), 60, 80, 100 e 120 DAE (avaliação 2) e 60, 80, 100, 120 e 140 DAE (avaliação 3) de sombreamento. As mudas de jaracatiá submetidas a diferentes períodos sob condições de sombreamento sofreram alterações nos parâmetros morfológicos e nos índices para avaliação da qualidade. As mudas que ficaram sob maiores períodos de sombreamento aos 100 DAE alcançaram maior altura da parte aérea, maiores relações altura da parte aérea/diâmetro do coleto e da massa de matéria seca da parte aérea/massa de matéria seca do sistema radicular. Nessa avaliação, as plantas apresentaram também os menores valores de diâmetro de coleto, massa de matéria seca do sistema radicular e do Índice de Qualidade de Dickson. O aumento do período de sombreamento refletiu negativamente no desenvolvimento do sistema radicular das mudas aos 100, 120 e 140 DAE. Aos 120 DAE, foram atingidos os padrões de qualidade considerados como mais adequados para o plantio definitivo. O melhor tratamento foi aquele em que as mudas permaneceram 60 dias em sombreamento, seguidos de 60 dias a pleno sol.Palavras-chave: Jacaratia spinosa; Índice de Dickson; Qualidade fisiológica.
