ResumoOs jangadeiros são populações de pescadores artesanais das orlas marítimas que vivem no litoral nordeste brasileiro. O litoral sul da Bahia é uma das poucas regiões do litoral brasileiro onde a cultura viva da pesca com a jangada tradicional ainda persiste. O presente estudo teve como objetivo realizar o levantamento das espécies arbóreas utilizadas para a construção de jangadas tradicionais na região sul da Bahia, investigando as possíveis origens desse conhecimento mantido pelos pescadores artesanais. O levantamento foi realizado no distrito de Serra Grande, Uruçuca, Bahia, entre abril e maio de 2013, através de 13 entrevistas semi-estruturadas. Os resultados foram analisados de forma qualitativa. Um total de 13 espécies foram citadas. As espécies mais citadas foram Apeiba tibourbou (Malvaceae) e Albizia polycephala (Fabaceae). A continuidade do conhecimento acerca da pesca artesanal com jangadas vem sendo comprometida devido à dificuldade em extrair a matéria-prima. Foi detectada a introdução de um novo componente nas jangadas tradicionais, o motor, entre quatro a sete anos atrás. Os resultados obtidos nesse estudo demonstram a importância da relação da comunidade estudada com o meio em que vivem e das espécies utilizadas na confecção das jangadas, mantendo viva uma cultura que praticamente desapareceu em outras regiões. No entanto, são necessárias medidas urgentes para que essa cultura não desapareça em função de mudanças de hábitos e de dificuldades legais e logísticas para a obtenção de matéria-prima. Palavras-chave: Conservação da biodiversidade, etnobotânica, Mata Atlântica. AbstractThe "jangadeiros" are populations of artisanal fishermen of coastlines living in the northeastern Brazilian coast. Currently, it appears that only in some regions such as the southern coast of Bahia, the living culture of fishing with handmade rafts still persists. The present study aimed to survey tree species used for building handmade rafts in southern Bahia, investigating the possible sources of this knowledge kept by artisanal fishermen. The survey was conducted in the district of Serra Grande, Uruçuca, Bahia, between April and May 2013, through 13 semi-structured interviews. The results were analyzed qualitatively. A total of 13 species were cited. The most cited species are Apeiba tibourbou (Malvaceae) and Albizia polycephala (Fabaceae). The continuity of knowledge of artisanal fishing has been compromised due to the difficulty in extracting the raw material. A new component was introduced in traditional rafts, the engine, between four and seven years ago. The results of this study demonstrate the importance of the relationship of the community and the environment in which they live and the species used in the making of rafts, keeping alive a culture that disappeared in other regions. However, urgent actions are needed so that the culture does not disappear due to changes in habits and legal and logistical difficulties in obtaining raw materials.

“…Although jackfruit dispersal is predominantly barochoric in the Atlantic forest leading to high rates of seed clumping below the mother-tree (Abreu & Rodrigues, 2010) we observed that sinzoochory by mammals also occurred. This result corroborates the findings of Novelli et al (2010) who performed experiments on barochoric dispersal of A. heterophyllus on sloping terrain.…”

“…Our results do not agree with previous studies such as Pizo & Vieira (2004), who found predation rates of native Euterpe edulis palms by generalist rodents not to be dependent on plant density. However, we believe that because jackfruit trees occur in high density (Abreu & Rodrigues, 2010;Bergallo et al 2016), and because the fruit is one of the largest of all tree species (Elevitch & Manner, 2006) the number of fruits and consequently seed availability surpass mammal consumption capacity during more intense fruit production periods. This is corroborated by the fact that adult jackfruit density was high in the three grids and seed predation was low during more intense fruit production periods.…”

“…It has an invasive status in French Polynesia, Venezuela (Ojasti et al, 2001), and Brazil, where it was intentionally introduced in the early 19 th century (Zenni & Ziller, 2011). Nowadays, jackfruit is one of the most conspicuous invasive plants in Brazil even in protected areas (Abreu & Rodrigues 2010, Bergallo et al 2016. Jackfruit affects native plants by allelopathic action, and its intense use by humans and other animals may have facilitated its spread (Bergallo et al, 2016).…”

The alien species Artocarpus heterophyllus, originally from India, was introduced to Brazil in the colonial period and has become invasive in some areas in the Atlantic Forest. Its fruits can weigh 35 kg and produce up to 500 seeds each. In their native range they are dispersed by turtles, rodents, monkeys, wild pigs and elephants. This study aimed to investigate the influence of mammals in jackfruit predation and seed dispersal, as well as the influence of jackfruit in native plant species dispersal by mammals, in the Ilha Grande State Park, Southeastern Brazil. Seeds with and without mesocarp were tied to thread spools and checked for predation and dispersion on 37 sites. We recorded mesocarp or jackfruit seed feeding on video. Six species of mammals were recorded feeding on jackfruit, but Trinomys dimidiatus, Didelphis aurita and Cuniculus paca accounted for 92% of all records. Cuniculus paca and Trinomys dimidiatus preyed and dispersed seeds while Didelphis aurita consumed mesocarp only. Seeds with mesocarp were more preyed on than seeds without mesocarp and its consumption was lower during more intense fruit production. Hence, jackfruit production can exceed the capacity of mammals to consume its seeds in areas where jackfruit density is high. Faeces of small mammals were collected in areas with (10 grids) and without jackfruits (8 grids) and analysed for the presence of native seeds. Twelve small mammal species were captured in areas with and without jackfruits, but faeces of 11 species were collected. Didelphis aurita dispersed proportionally more native seeds in area without jackfruits. Our results showed that mammals are playing a negative role helping to disperse jackfruit trees, and this is occurring in different ways depending on mammal species.

Biological invasions have contributed to biodiversity loss, ecosystem degradation, and impairment of ecosystem services worldwide, requiring actions towards their prevention and control. Since human and monetary resources are both limited in most countries, priorities must be settled in the real world of biological invasion prevention and control. To support the decision making process regarding plant species already introduced, we propose a classification key, based upon biogeographical and ecological attributes of the target plant population. The key shall be applied to a particular biogeographical region, based on the premise that a species never invades two distinct ecosystems in the same way. The key categorizes the species according to the potential threats offered to the native biodiversity and ecosystem services in that region. Management strategies are recommended on the basis of both the species performance as invader and its economic importance in the region. We highlight the importance of ecological studies to categorize a species by the threats it offers to a specific ecological region, in order to avoid the waste of efforts and resources with non-risky species. Eradication experiments are equally important to find ecologically, technically and economically viable solutions for the problems derived from biological invasions.
