Dispersão por aves de Psidium guajava L. (Myrtaceae) em ambiente ripário na bacia do rio Paraná, Brasil

Abstract: A dispersão da goiabeira (Psidium guajava L.) em ecossistemas naturais brasileiros é um processo crescente e requer estudos sobre a dinâmica desta espécie. Deste modo, os objetivos foram: a) identificar quais espécies de aves se alimentam dos frutos de Psidium guajava; b) descrever as principais táticas de forrageamento das aves, que podem maximizar ou reduzir o sucesso de dispersão da goiabeira. Foram realizadas 47 horas de observação focal de aves consumindo frutos de P. guajava, onde foram registradas 11 es… Show more

“…The P. guajava dominance success can be attributed to the combination of its regrowth and its edible fruits being dispersed by various birds, monkeys, among other mammals, and even insects. 71 In addition to its excellent dispersion, the guava tree is established preferentially in disturbed areas, soils with good humidity, and more open and illuminated places, such as the edges of forest fragments, causing a major impact on the native flora due to the shading it causes in areas dominated by this species. 70 Also, P. guajava has several adaptive advantages when compared to native forest species, being usually more efficient.…”

“…Guava (Psidium guajava L.) is a perennial fruit crop of family Myrtaceae. The fruits present sweet-acidified flavor and pleasant aroma, which is the major reason for its great variety of products, uses and forms of consumption (Velho et al, 2011;Campos et al, 2013). In Brazil, guava is cultivated in a wide area, reaching 20,294 hectares of land with average annual production of 460,515 tons (IBGE, 2017).…”

“…In Brazil, guava is cultivated in a wide area, reaching 20,294 hectares of land with average annual production of 460,515 tons (IBGE, 2017). In addition, due to the attractiveness of the fruit to the fauna, the species present good dispersion capacity, and is used in the recomposition of degraded areas (Silva et al, 2013).…”

“…No entanto, poucos trabalhos relacionados à ecologia da dispersão têm sido desenvolvidos para espécies de Myrtaceae no Brasil (e.g., Pizo, 2003;Gressler et al, 2006;Côrtes et al, 2009;Silva et al, 2013; este estudo). Considera-se que além da conservação da biodiversidade esses estudos possibilitam apontar potenciais de uso das espécies, seja na restauração de ecossistemas, seja na arborização ou em processos de domesticação de plantas.…”
