ABSTRACT<\/strong><\/p>\n

The urbanization process causes rearrangements of the flora through disturbances, affecting composition, structure and biodiversity of the remnants. In Brazil, the Atlantic Forest is the biome that has suffered the most loss of area to urbanization and agriculture. In addition, even highly fragmented it still maintains a profuse biodiversity being one of the most important global biodiversity hotspots. In the Atlantic Forest observes that such rearrangements promote loss of biodiversity and biotic heterogeneity. It increasing susceptibility to homogenization (increasing similarity levels) through the proliferation of specific groups of native and non-native invasive species, making landscapes more homogeneous and less resilient to environmental changes. The present study aimed to characterize the composition and structure of the urban forest remnant in the Vila dos Rem\u00e9dios Municipal Park. It determines the floristic similarity of the fragment with others located in S\u00e3o Paulo metropolitan area and the similarity of reproductive characteristics in dispersion and pollination syndrome in order to determine the occurrence of biotic homogenization. The Park has a total area of 10.98 ha such 8.0 ha of remainder. In these 8.0 ha, 10 transects of 2 x 50 m were randomly arranged and without overlap. The sampling of individuals was differentiated into three size classes (CT): CT3 (dap \u2265 2.5 cm), CT2 (dap <2.5 cm) and CT1 (individuals between 30.0 and 1.30 cm in height in a subplot of 1 x 10 m randomly chosen within each of the 2 x 50 m transections). A total of 1059 individuals were sampled distributed in 99 species, 79 genera and 40 families. Fabaceae was the family with the highest species richness followed by Myrtaceae, Lauraceae, Rubiaceae and Piperaceae. Most species were classified as early secondary, zoochoric and zoophilic. The species with the highest dominance and importance value for CT3 were Guarea macrophylla<\/em>, Aiouea montana<\/em>, Coffea arabica<\/em>, Myrciaria floribunda <\/em>and Archontophoenix cunninghamiana<\/em>. The basal area in CT3 was 68.63 m\u00b2 ha\u02c9\u00b9 and the density was 3330 individuals ha\u02c9\u00b9. The great contribution of non-native invasive species C<\/em>. arabica <\/em>and A<\/em>. cunninghamiana <\/em>to the structure of the Park characterizes as disturbed due to biological invasion. The remnants compared with Vila dos Rem\u00e9dios Park were those municipal parks: Santo Dias, Trianon, Alfredo Volpi, Burle Marx and Previd\u00eancia; a section of Parque Estadual Fontes do Ipiranga (PEFI) and; three wood sections of Instituto Butantan (areas of Remanescente, Eucaliptal and Lago Drenado). Among the remnants compared, the highest values of diversity and richness were obtained in PEFI and Previd\u00eancia. In addition, the lowest values were obtained in Vila dos Rem\u00e9dios and in three sections of Instituto Butantan.\u00a0From the ordination by nonmetric multidimensional scaling, it was observed that all the remnants are dissimilar from each other. Except condition for the pair formed between Burle Marx and Previd\u00eancia, and the section of Butantan Remanescente and Vila dos Rem\u00e9dios. Comparing the remnants in S\u00e3o Paulo metropolitan area it is possible to affirm that the biotic homogenization process is not established yet, due to the floristic dissimilarity between them. Biotic heterogeneity in the metropolitan area is highlighted if the predominance of secondary species (early and late) and zoochoric species. However, Vila dos Rem\u00e9dios Park and Butantan Institute wood have low diversity that is associated with biological invasion; these make them the remnants more susceptible to homogenization.

RESUMO<\/strong><\/p>\n

O processo de urbaniza\u00e7\u00e3o causa rearranjos na flora atrav\u00e9s de perturba\u00e7\u00f5es, que afetam composi\u00e7\u00e3o, estrutura e biodiversidade dos remanescentes. No Brasil a Mata Atl\u00e2ntica \u00e9 o bioma que sofreu maior perda de \u00e1rea para a urbaniza\u00e7\u00e3o e agricultura e, mesmo que altamente fragmentada, ainda mant\u00eam uma profusa biodiversidade, sendo um dos importantes hotspots <\/em>globais de biodiversidade. Na Mata Atl\u00e2ntica observa-se que tais rearranjos promovem perdas da biodiversidade e na heterogeneidade bi\u00f3tica, aumentando a suscetibilidade \u00e0 homogeneiza\u00e7\u00e3o (aumento dos n\u00edveis de similaridade) atrav\u00e9s da prolifera\u00e7\u00e3o de grupos espec\u00edficos de esp\u00e9cies nativas e n\u00e3o-nativas invasoras, tornando as paisagens mais homog\u00eaneas e menos resilientes \u00e0s mudan\u00e7as ambientais. O presente estudo teve como objetivos caracterizar a composi\u00e7\u00e3o e estrutura de um remanescente florestal urbano do Parque Municipal Vila dos Rem\u00e9dios; determinar a similaridade flor\u00edstica e de s\u00edndromes de dispers\u00e3o e poliniza\u00e7\u00e3o, com outros remanescentes da regi\u00e3o metropolitana de S\u00e3o Paulo, a fim de se detectar a poss\u00edvel ocorr\u00eancia de homogeneiza\u00e7\u00e3o bi\u00f3tica. O Parque apresenta \u00e1rea total de 10,98 ha, <\/em>sendo 8,0 ha do remanescente. Nesses 8,0 ha foram estabelecidas 10 transec\u00e7\u00f5es de 2 x 50 m dispostas aleatoriamente e sem sobreposi\u00e7\u00e3o. A amostragem dos indiv\u00edduos foi diferenciada em tr\u00eas classes de tamanhos: CT3 (dap \u2265 2,5 cm), CT2 (dap < 2,5 cm) e CT1 (indiv\u00edduos de altura entre 30,0 e 130,0 cm em uma subparcela de 1 x 10 m escolhida aleatoriamente dentro de cada uma das transec\u00e7\u00f5es de 2 x 50 m). No total foram amostrados 1059 indiv\u00edduos distribu\u00eddos em 99 esp\u00e9cies, 79 g\u00eaneros e 40 fam\u00edlias. Fabaceae foi a fam\u00edlia com maior riqueza de esp\u00e9cies seguida por Myrtaceae, Lauraceae, Rubiaceae e Piperaceae. A maioria das esp\u00e9cies s\u00e3o secund\u00e1rias iniciais, zooc\u00f3ricas e zoof\u00edlicas. As esp\u00e9cies com maior domin\u00e2ncia e valor de import\u00e2ncia para CT3 foram Guarea macrophylla<\/em>, Aiouea montana<\/em>, Coffea arabica<\/em>, Myrciaria floribunda <\/em>e Archontophoenix cunninghamiana<\/em>. A \u00e1rea basal na CT3 foi de 68,63 m\u00b2 ha\u02c9\u00b9 e a densidade de 3330 indiv\u00edduos ha\u02c9\u00b9. A grande preval\u00eancia estrutural das esp\u00e9cies n\u00e3o-nativas invasoras C<\/em>. arabica <\/em>e A<\/em>. caracterizam o Parque Vila dos Rem\u00e9dios como perturbado devido \u00e0 invas\u00e3o biol\u00f3gica. Os remanescentes comparados com o Parque Vila dos Rem\u00e9dios foram os Parques Municipais Santo Dias, Trianon, Alfredo Volpi, Burle Marx e Previd\u00eancia, um trecho do Parque Estadual Fontes do Ipiranga (PEFI) e tr\u00eas trechos da mata do Instituto Butantan (trecho de Remanescente, Eucaliptal e Capoeira sobre Lago Drenado). Entre os remanescentes comparados, os maiores valores de diversidade e riqueza foram encontrados no PEFI e Parque Previd\u00eancia e os menores nos tr\u00eas trechos do Instituto Butantan e Parque Vila dos Rem\u00e9dios.\u00a0Pela ordena\u00e7\u00e3o por escalonamento multidimensional n\u00e3o m\u00e9trico, todos os remanescentes analisados s\u00e3o dissimilares entre si, com exce\u00e7\u00e3o do par formado pelos Parques Burle Marx e Previd\u00eancia e o trecho de Remanescente do Butantan e o Parque Vila dos Rem\u00e9dios. Comparando os remanescentes da regi\u00e3o metropolitana de S\u00e3o Paulo \u00e9 poss\u00edvel afirmar que o processo de homogeneiza\u00e7\u00e3o bi\u00f3tica ainda n\u00e3o est\u00e1 estabelecido devido \u00e0 dissimilaridade flor\u00edstica entre eles. A heterogeneidade bi\u00f3tica na regi\u00e3o metropolitana \u00e9 evidenciada pela predomin\u00e2ncia de esp\u00e9cies secund\u00e1rias (iniciais e tardias) e zooc\u00f3ricas. Entretanto, o Parque Vila dos Rem\u00e9dios e a mata do Instituto Butantan por apresentarem baixa diversidade, associada a intensa invas\u00e3o biol\u00f3gica, s\u00e3o os remanescentes mais suscet\u00edveis \u00e0 homogeneiza\u00e7\u00e3o.
