“…Zoochory is the most common way of seed dispersal in tropical forests (Barcelos et al, 2012;Gonçalves et al, 2015 and references therein). Animal-dispersed fruits are usually fleshy berries or drupe, or dehiscent capsules that expose the seeds involved with an aril, which contains sources of carbohydrates and lipids (Fleming and John Kress, 2011).…”

“…Birds are the main frugivorous in the Neotropics and are efficient seed dispersers because they are very mobile and have high metabolism that requires constant energy consumption (Whelan et al, 2008;Gonçalves et al, 2015). They also show color sensitivity (Hart, 2001) and well developed brain and vision, which allow for learning (Martin, 1993).…”

Fruit color preference by birds and applications to ecological restoration

Ecological restoration aims to retrieve not only the structure but also the functionality of ecosystems. Frugivorous birds may play an important role in this process due to their efficiency in seed dispersal. Color perception in these animals is highly developed, and then the colors of fleshy fruits may provide important clues for choosing plant species for restoration plans. This study aims to integrate bird color preferences and restoration of degraded areas, with an objective to evaluate the potential attractiveness to birds by colored fruits. We carried out an experiment with 384 artificial fruits made of edible modeling clay with the following colors: black, blue, green and red, with 96 fruits of each color in six sites, including four restored areas and two second-growth forest fragments. We also tested the possible effect of light intensity on fruit consumption by color. A total of 120 (38.6%) were assumed to be consumed by birds, and the fruit consumption varied in response to the location and light incidence. Consumption of black and blue fruits was not related to site by chance. Notwithstanding, red and black fruits were consumed significantly more than any other colors, emphasizing bird preference to these colors, regardless of location. Enrichment with shade tolerant shrubs or forest species with black or red fruits may be an alternative way to manage established restorations. In recently established or new restorations, one may introduce pioneer shrubs or short-lived forest species which have blue fruits, but also those having black or red ones.Keywords: artificial fruits, Atlantic Forest, frugivory, ecological succession, color perception. Preferência de cor de frutos por aves e aplicações à restauração ecológica ResumoA restauração ecológica tem a finalidade de recuperar não apenas a estrutura, mas também a funcionalidade dos ecossistemas, e as aves frugívoras podem desempenhar um papel importante neste processo devido à sua eficiência na dispersão de sementes. Como a percepção da cor nestes animais é altamente desenvolvida, a cor dos frutos carnosos pode ser uma característica importante na escolha de espécies de plantas para os reflorestamentos. Este estudo tem como foco integrar a preferência de cor de frutos por aves e a recuperação de áreas degradadas, objetivando determinar a atratividade potencial de aves por frutos de cores diferentes. Foi realizado um experimento com 384 frutos artificiais feitos com massa de modelar comestível nas cores preta, azul, verde e vermelha, com um total de 96 frutos em cada cor em seis locais, incluindo quatro áreas restauradas e dois fragmentos de floresta secundária. Também foi testado o possível efeito da intensidade de luz sobre o consumo de frutos conforme as cores. Um total de 120 (38,6%) frutos foi considerado consumido pelas aves, e o consumo variou em resposta aos locais e incidência de luz. O consumo de frutos pretos e azuis foi significativamente relacionado com o local. Os frutos vermelhos e pretos foram significativamente mais consumidos do...

“…The dispersion potential (DP), which measures the efficiency of a species as seed disperser from the number of whole swallowed diaspores and the time spent on the complete visits, was also estimated for each species of bird using the calculation DP = [f/t.(n)]. Given f the mean number of intact swallowed diaspores from fruits; t the average time the bird stayed on the plant in complete visits; n the number of complete visits per hour (GONÇALVES et al, 2015).…”

Espinheira-santa (Monteverdia ilicifolia) is a native plant of Brazil widely used in folk medicine because it has several therapeutic properties. Regarding the pollination biology and seed dispersal of this species, there is no information available in the literature. In this study, pollinators and dispersers of M. ilicifolia were observed and identified, as well as the behavior of these biological agents during the period of flowering and fruiting. In addition, the frequency of pollinator visits and the efficiency of the seed disperser were recorded. It was verified that in espinheira-santa, pollination is carried out by diptera and by hymenoptera. Among the main groups of pollinators are the flies, being Lucilia eximia, Limnophora sp. and Eristalis sp. the most frequent, and the wasps, in which Brachygastra mellifica, Polistes canadensis, Mischocyttarus sp. and one species of the Tiphiidae family were the most frequent. Eight species of birds consumed diaspores (arils with seeds), acting as dispersers of this species. However, the following birds were more efficient in the dispersion of seeds: Tangara sayaca, Elaenia sp. and Pipraeidea bonariensis. In this sense, M. ilicifolia is a species that has entomophilous pollination and ornithochoric dispersion.

“…Seeds are carried to suitable places for germination and establishment (i.e., far from the mother plant and seed predators), or seed germination is increased (Janzen, 1970;Connell, 1971;Traveset, 1998). Studies with plant species in early secondary succession may elucidate seed dispersal strategy, and may help to identify plant species for inclusion in ecological restoration programs Gonçalves et al, 2015).…”

The goal of this study was to identify which bird species consume Solanum granuloso-leprosum fruits and disperse its seeds. 60 hours of focal observations were carried out between April and May 2006 on the edge of a deciduous forest fragment in the Uruguay River region, Rio Grande do Sul state, Brazil. Ten species were observed in total removing 443 fruits. Saltator similis removed 61.8% of the fruits, followed by Tangara sayaca (17.1%), Pipraeidea bonariensis (11.7%), and T. preciosa (6.8%), while the remaining six species accounted for only 2.5% of the fruits removed. Most fruit removal occurred early in the day or mid-afternoon. The most common feeding behaviors were picking (60.7%), followed by stalling (23%) and hovering (16%). Birds flew more than 10 m from the fruit plant in 62% of the removal events. All bird species observed here may be considered potential dispersers of S. granuloso-leprosum, as they moved the seeds away from the mother plant where strong competition and predation are likely to occur. Results also suggest that S. granuloso-leprosum may be useful in ecological restoration programs.Keywords: mother plant, ornitochory, pioneer plant, secondary fragment forest. Frugivoria e dispersão de sementes em Solanum granuloso-leprosumDunal (Solanaceae) por aves em Floresta Estacional Decidual ResumoO objetivo deste estudo foi identificar quais as espécies de aves consomem frutos de Solanum granuloso-leposum e dispersam suas sementes. Para tanto, 60 horas de observações focais foram realizadas entre abril e maio de 2006 na borda de um fragmento de floresta decídua na região do rio Uruguai, Rio Grande do Sul, Brasil. Dez espécies foram observadas removendo 443 frutos. Saltator similis removeu 61,8% dos frutos, seguido de Tangara sayaca (17,1%), Pipraeidea bonariensis (11,7%), e T. preciosa (6,8%), enquanto as restantes seis espécies representaram apenas 2,5% dos frutos removidos. A maioria das remoções dos frutos ocorreram no início do dia ou meio da tarde. Os comportamentos alimentares mais comuns foram picking (60,7%), seguido por stalling (23%) e hovering (16%). As aves voaram mais de 10 m da planta de onde removeram frutos em 62% dos eventos de remoção. Todas as espécies de aves observadas aqui podem ser consideradas potenciais dispersores de S. granuloso-leprosum, moveram sementes para longe da planta-mãe, onde a concorrência e a predação são mais susceptíveis de ocorrer. Os resultados também sugerem que S. granuloso-leprosum pode ser útil em programas de restauração ecológica.Palavras-chave: planta mãe, ornitocoria, planta pioneira, fragmento de floresta secundária.
