“…Furthermore, at that time, the species joined the list of trees used to recover part of the massif of Tijuca (RJ), exhausted by coffee and sugarcane monoculture (DEAN, 1996). This species has easily adapted to Brazil by several factors, such as a high annual production of fruit and absence of specific predators, besides serving as a food source for several species of native animals (PEREIRA; KAPLAN, 2013). In the early twentieth century, jack trees were used in gardens, farms, country houses, and orchards of this city, wherein its fruit is commonly found in small shops (grocery stores), local markets, street vendors and in free markets .…”

“…This species was introduced into Brazil by the Portuguese Royalty, in the seventeenth century, due to a mercantilist policy aiming to acclimatize plants and spices from Asia (PEREIRA; KAPLAN, 2013). The jack tree has become part of a list of alien species widely used in landscaping projects by Auguste Glaziou, who was hired by D. Pedro II, in the mid-nineteenth century, to serve as director of the Rio de Janeiro's division of parks and gardens, in Boa Vista and Campo de Santana (SANTOS et al, 2008).…”

Invasion impact of Artocarpus heterophyllus LAM. (Moraceae) at the edge of an atlantic forest fragment in the city of Rio de Janeiro, Brazil

ABSTRACT:The Atlantic Forest is reduced to less than 20 % of its original area, but it still protects an important biological heritage. Forest fragmentation makes the environment more susceptible to invasive species occupation. Jackfruit (Artocarpus heterophyllus) was introduced into Brazil in the seventeenth century; and in the second half of the twentieth century, its natural regeneration increased the density of individuals, compromising the recruitment of many native species. This study investigated the impact of A. heterophyllus invasion on the diversity and tree structure component at the edge of an Atlantic Forest fragment, in Rio de Janeiro (Brazil). Two transect-type plots were set up with 10 m x 100 m (1,000 m 2 ), being divided into 10 subplots of 10 m x 10 m, with a total sampling area of 2,000 m 2 . Trees with a diameter at breast height (DBH) equals to or greater than 5 cm were tagged and DBH and total height measured. The following phytosociological parameters were estimated: Frequency (F), Density (D), Dominance (Do), Importance (IV) and Coverage (CV) Values. In total, 191 tree individuals were sampled. Invasive species made up more than 35% of the entire vegetation structure in the studied environment, ending in first place in terms of Importance Value (IV = 35.62%). Low floristic wealth seems to have favored the A. heterophyllus invasion process in the community, showing the need for an effective control of the species for the native genetic heritage protection.

“…Com relação as classes climáticas, houve uma predominância das espécies nas regiões com climas do tipo As, Aw, Cfa, Af e Bsh. Esses climas são os mesmos das regiões de origem das espécies (Azzini & Salgado, 1981;Pereira & Kaplan, 2013;Sciamarelli et al, 2013). Portanto, possivelmente isso pode ter contribuído para tal resultado pois existem quatro fatores responsáveis pelo estabelecimento de espécies exóticas invasoras e, dentre eles, está a similaridade climática (Fatma, 2016).…”

As invasões biológicas contribuem de forma significativa para a perda de biodiversidade global. Apesar do crescente número de trabalhos sobre a temática, ainda são necessários estudos que abordem a distribuição dessas espécies. O objetivo deste estudo foi avaliar a dispersão de cinco espécies exóticas invasoras (Artocarpus heterophyllus, Crotalaria retusa, Leucaena leucocephala, Megathyrsus maximus e Prosopis juliflora) em razão do bioma, clima, Unidades de Conservação Federais e uso e ocupação dos solos. Para isso, foram obtidos pontos de ocorrência georreferenciados das espécies nas bases de dados specieslink e Gbif. Esses pontos foram plotados nos mapas temáticos confeccionados no software Qgis 3.18.3. A espécie M. maximus foi a que apresentou maior número de registros no Brasil (644), seguida por C. retusa (446), L. leucocephala (426), A. heterophyllus (315) e P. juliflora (150). O bioma com maior ocorrência das exóticas invasoras foi a Mata Atlântica (948), seguido pela Caatinga (423) e Cerrado (334). A maioria dos táxons apresentou ocorrência em quase todas as classes climáticas. Quanto a distribuição das espécies nas unidades de conservação federais, C. retusa esteve presente em 40 delas, M. maximus em 20, L. leucocephala em 10, A. heterophyllus em cinco e P. julifora em quatro. Todas as espécies apresentaram maior ocorrência em sítios com uso e ocupação dos solos antrópicos. Nossos resultados revelaram que as espécies avaliadas apresentam ampla distribuição pelo território brasileiro e ocorrem em boa parte das condições investigadas, portanto, é necessário que políticas públicas sejam criadas a fim de promover a erradicação dessas espécies.

“…Due to its food use, the jackfruit tree was introduced in Brazil in the 17th century, and was later used in reforestation projects in the state of Rio de Janeiro (Pereira & Kaplan, 2013). Today, the jackfruit tree is widely distributed throughout the Brazilian territory and is known as an aggressive invasive exotic species in the Atlantic Forest of the Northeast and Southeast of Brazil (Fabricante et al, 2012;Moura et al, 2020).…”

Artocarpus heterophyllus is an invasive exotic species known for its negative impacts on Brazilian ecosystems. The aim of this study was to evaluate the distribution and population structure of A. heterophyllus in the plant community of a forest fragment in the Amazon. Individuals of this species were subject to active search at Sumaúma State Park, in Manaus, and two plots were delimited, where these individuals were counted. In each plot, the jackfruit tree individual with the largest Diameter at Breast Height (DBH) was centralized, and from it, native species were inventoried. The parameters of relative density, relative dominance and the importance value index were estimated. Jackfruit tree individuals in the plots had grouped distribution and their number in plots 1 and 2 was 308 and 872 individuals, respectively. In quadrant 1, 254 jackfruit trees and 118 native individuals were recorded, and in quadrant 2, 629 jackfruit and 130 native individuals. The jackfruit tree reached indices higher than the sum of the phytosociological indices of all native species. Jackfruit tree distribution was considered similar to that occurring in other already invaded areas of Brazil, which may indicate that the same impacts may occur in Amazonian ecosystems.
