Redes de interações de frugivoria por aves em plantas nativas e exóticas em ambiente urbano

Abstract: Fruit consumption by birds is well reported in Brazil, but few studies compared the use of native and exotic fruit, especially in urban environment. Network Theory may be a useful tool in such studies, since it allows to evaluate multiple species of both animal and plants involved in interactions. The goals of this thesis were to evaluate bird-plant interaction networks in urban environment on regional and local scale; to assess the role of native and exotic plant species in the networks and to compare the con… Show more

“…Since S. coronata is found growing in semiarid regions, being subjected to its extreme climate (e.g., intense insolation, daytime temperature variation, and scarce water), it has adaptations to survive in these environments. For instance, in order to avoid desiccation, its leaflets present thick cuticle, non-vascular fiber bundles in the mesophyll, compact chlorenchyma, densely vascularized, and adaptations of its photosynthetic mechanisms (Leite and Scatena, 2001;Castro, 2016;Oliveira et al, 2016). Furthermore, during leaf senescence, the licuri palm still retains green leafsheaths for three to four years, working as water and nutrient storage.…”

“…No entanto, esse tipo de atividade tem resultado na supressão da vegetação original, incluindo áreas marginais aos corpos hídricos. Esse processo de remoção da vegetação tem consequências diretas na dinâmica das bacias hidrográficas, causando a erosão do solo e o assoreamento dos corpos hídricos (Oliveira;Aquino, 2020).…”

“…As pesquisas nesta área tendem a facilitar o modo correto de manejo da vegetação com finalidade utilitária, pois empregam os conhecimentos tradicionais obtidos para solucionar problemas de saúde ou para fins conservacionistas (BECK; ORTIZ., 1997). Tanto a etnobotânica como a etnofarmacologia têm demonstrado ser poderosas ferramentas na busca por substâncias naturais de ação terapêutica (ALBUQUERQUE; HANAKI, 2006), onde estudos comparativos entre o método etnodirigido e o randômico tem revelado a superioridade do primeiro em relação ao segundo ( SLISH et al, 1999;KHAFAGI;DEWEDAR, 2000;OLIVEIRA et al, 2011).…”

“…No S.Bu estavam presentes com maior intensidade as saponinas e triperternos; enquanto, S.Aq apresentou somente as saponinas. Os esteróides só foram encontrado no S.He (Tabela 3).Os terpenos estão envolvidos em diferentes funções nos vegetais, desde a composição de alguns óleos essenciais de plantas (monoterpenos), o que confere características como a atração de polinizadores; ação inseticida e antimicrobiana (sesquiterpenos), dentre outras(OLIVEIRA, 2007). As atividades biológicas de terpenos distribuem-se dentro de vários grupos.…”
