“…Snow (1981) characterized fruit produced by the Miconia species as a good example of those consumed preferentially by opportunistic birds as the fruit is small and juicy and bears many small seeds. Our results confirm a general dispersal system for M. ligustroides, while a similar study conducted on M. albicans, in the same study area, registered nineteen opportunistic bird species consuming its fruit (Allenspach and Dias, 2012). The guilds consuming M. albicans and M. ligustroides fruit are similar (Jaccard Index = 0.67) and the dissimilarities can possibly be explained by different fruiting seasons, migrant bird species and the sites of the trees in the studied area.…”

We identified the avian assembly that consumes Miconia ligustroides (Melastomataceae) fruit and described its phenophases in a fragment of cerrado vegetation located in southeastern Brazil. The fruiting period occurred between March and June, a period of food shortage. In 2005 and 2008, we registered eighteen bird species consuming fruits, during 156 hours of observations. Species of the families Thraupidae and Tyrannidae were the most representative in the number of visits and fruit consumption. Short visits (less than three minutes) and low incidence of defecation apparently indicate that seeds may be released far from the parent-plant, suggesting dispersal efficiency by the studied assembly. Owing to its characteristics, we believe Miconia ligustroides may be useful in the restoration of degraded areas.Keywords: cerrado, frugivory, Miconia, ornitochory, phenology.

Interactions between frugivorous birds and plants in savanna and forest formations of the Cerrado

et al. 2014

We recorded interactions between frugivorous birds and plants in the Cerrado and we assessed the role and importance of birds as potential seed dispersers. We analyzed the distribution of recorded feeding events, bird-plant interactions, and bird species composition between savanna and forest formations and between the dry and rainy seasons. Samplings were carried out from August 2009 to October 2010 and from November 2011 to August 2012 by means of line transects and focal observations. We recorded 348 feeding events and 187 interactions involving 44 plant species and 60 bird species. Most of the feeding events were observed in the forests and during the dry season (χ2 = 39.529; gl = 1; p < 0.001). However, no significant difference was found in the number of interactions (χ2 = 15.975; gl = 1; p = 0.06) between the two vegetation formations and between seasons. The bird species composition differed between savanna and forest formations (ANOSIM, R = 0.238; p < 0.001) and between the dry and rainy seasons (ANOSIM, R = 0.223; p < 0.001). Most of the potential seed dispersers were generalist birds that preferentially occupy forests during the dry season. Records of feeding events in forest formations increased in the dry season, indicating that birds use these sites as foraging areas during this period. We suggest that the preservation of forests in predominantly savanna-like ecosystems such as the Cerrado is extremely important for frugivorous birds and for frugivore-plant interactions.

“…This species is apomictic, producing sterile pollen and receiving few visits by pollinators (Goldenberg and Shepherd, 1998). Its flowers are small and white and stay open for only a short period of time (Allenspach and Dias, 2012). It produces numerous small fruits which contain high levels of water and carbohydrates (Maruyama et al, 2007) and are consumed by at least 19 bird species (Allenspach and Dias, 2012).…”

“…We expected that, according to previous studies on M. albicans (Hoffmann, 1998;1999), the time after the fire would not have been sufficient for the two species to recover, with smaller reproductive output by burnt plants. The two species are physiologically similar in a number of aspects: they are evergreen (Damascos et al, 2005;Lucena et al, 2015), respond to fire by intense resprouting which results in little difference in plant density between burnt and unburnt sites (Lucena 2009, Dodonov et al, 2014, produce small flowers (Goldenberg and Shepherd, 1998;Durigan et al, 2004), and produce small fleshy fruits which are likely to be dispersed mainly by birds (Durigan, et al 2004;Allenspach and Dias, 2012). In addition, they are among the three most common woody plant species at the study site (Dodonov, 2015), indicating that they are highly adapted to the local environment.…”

Effects of an accidental dry-season fire on the reproductive phenology of two Neotropical savanna shrubs

2017

Fire is a recurrent disturbance in savanna vegetation and savanna species are adapted to it. Even so, fire may affect various aspects of plant ecology, including phenology. We studied the effects of a spatially heterogeneous fire on the reproductive phenology of two dominant woody plant species, Miconia albicans (Melastomataceae) and Schefflera vinosa (Araliaceae), in a savanna area in South-eastern Brazil. The study site was partially burnt by a dry-season accidental fire in August 2006, and we monitored the phenolology of 30 burnt and 30 unburnt individuals of each species between September 2007 and September 2008. We used restricted randomizations to assess phenological differences between the burnt and unburnt individuals. Fire had negative effects on the phenology of M. albicans, with a smaller production of reproductive structures in general and of floral buds, total fruits, and ripe fruits in burnt plants. All unburnt but only 16% of the burnt M. albicans plants produced ripe fruits during the study. Fire effects on S. vinosa were smaller, but there was a greater production of floral buds and fruits (but not ripe fruits) by burnt plants; approximately 90% of the individuals of S. vinosa produced ripe fruits during the study, regardless of having been burnt or not. The differences between the two species may be related to S. vinosa's faster growth and absence from the seed bank at the study site, whereas M. albicans grows more slowly and is dominant in the seed bank.
