“…In tropical forests, areas adjacent to linear gaps are characterized by low species richness, high proportion of pioneers and anemochorous plants and presence of exotic species, as reported in this study and others (Ribeiro et al 2009a;Reznik et al 2012;Prieto et al 2014). We also found that pathway width influences the nearby vegetation as much as its presence.…”

“…January- March 2017 Several studies addressed the changes in vegetation structure and composition at the edges of linear forest gaps (Demir 2007;Enoki et al 2012;Otto et al 2013;Li et al 2014) and just a few conducted in tropical forests focused on linear gaps caused by roads, gas pipelines and power lines (Reznik et al 2012;Prieto et al 2014;CoutoSantos et al 2015), or pastures (Ribeiro et al 2009a). In those studies, linear gaps aff ected the phenodynamics of animal dispersed plants (Reznik et al 2012), tree species structure and richness (Ribeiro et al 2009a;Couto-Santos et al 2015), and proportion of pioneer species (Prieto et al 2014). However, the extent to which the pathway width aff ects those forest attributes has never been properly assessed and understood.…”

Although impacts generated by gaps can aff ect vegetation, few studies have addressed these impacts in the Atlantic Forest. Our aim was to investigate the eff ects of pathways of varying widths on vegetation structure and composition, considering dispersal syndromes, diversity, life forms, successional categories and threatened and exotic species occurrence in the Atlantic Forest. We studied three pathways with widths of 2, 10 and 20 m, intersecting a protected area in southeastern Brazil. To assess edge eff ects, plots were established adjacent to paths (edge) and 35 m from the edge (neighborhood), and in a control area without pathways. Wider pathways (10 and 20 m) exhibited reduced tree height and diameter, high liana density, exotic species, and a high proportion of pioneer and anemochorous species. In conclusion, our results indicate that the vegetation structure of narrow pathways (2 m) is similar to the control area, and that wide linear gaps cause negative eff ects on vegetation and extend to a distance of at least 35 m into the forest interior. Considering that linear gaps generate permanent eff ects to vegetation and may aff ect other organisms, we suggest that these eff ects must be considered for successful management of protected areas, including planning and impact mitigation.

“…Esta diminuição pode ser, provavelmente, explicada pelo elevado incremento populacional que a Região Metropolitana do Recife vem apresentando nas ultimas décadas, o que influencia, consideravelmente, na urbanização através da construção de casas ou grandes residenciais em áreas com solo natural, como observado por Souza et al (2006a) (Zeng et al, 2009), redução na quantidade de habitat para espécies florestais que dependem de grandes fragmentos (Teixeira et al, 2009) e alterações nas condições microclimáticas locais (Bierregaard e Dale, 1996;Ribeiro et al, 2009). Souza et al (2006b) afirmam "que a arborização urbana traz muitos benefícios para a cidade e estes devem ser preservados para minimizar os transtornos causados pela falta de arborização.…”

Este ensaio trata do ambiente urbano numa perspectiva interdisciplinar, com base na discussão de conceitos que procuraram explicar as inter-relações entre sociedade e natureza a partir da geografia do Recife. Primeiro, reapresentamos a importância das inter-relações sociedade-natureza no conceito de ambiente urbano. Segundo, discutimos, mais especificamente, os conceitos de sítio e situação geográficos. Terceiro, consideramos os conceitos de higienismo, ecologia urbana e desenvolvimento sustentável. Por último, tecemos algumas considerações finais sobre o tema ora abordado.Palavras-chave: Ambiente Urbano, Inter-Relações Sociedade-Natureza, Sítio Urbano, Situação Geográfica, Ecologia Urbana, Desenvolvimento Sustentável, Recife. The Urban Environment an Interdisciplinary Perspective: Discussion of Concepts that Treat the Inter-Nature Relations, in the Geography of Recife A B S T R A C TThis essay reflects upon the urban environment under an interdisciplinarity vision, based on the discussion about concepts created in order to explain inter-relationships between society and nature, from a geography of Recife. Firstly, we introduce again the importance of relationships between society and nature under the concept in urban environment. Secondly, we discuss specially concepts of urban site and geography situation. Third, we consider concepts in hygienism, urban ecology and sustainable development. To conclude we consider some final points about the subject of this text.

“…In 2003, minimum and maximum monthly temperatures ranged from 12.6°C to 19.0°C and 23.8°C to 34.2°C respectively (Ramos & Santos 2006). The vegetation in the study area is evergreen forest, with 39 families and 132 morphospecies sampled in a 0.75 ha area (Ribeiro et al 2009).…”

We evaluated the ontogeny of the understory shrub Psychotria tenuinervis Müll.Arg., considering morphological and morphometric characters. Four ontogenetic stages were identified: seedling, juvenile, immature and adult (vegetative and reproductive phases). Size measurements and allometric relationships of the stem and crown were compared between the immature and adult stages. Diameter and total height of the stem, as well as crown depth and width, increased throughout the ontogenetic stages and differed among immature, vegetative adult and reproductive adult individuals. The number of branches was lower in immature individuals than in vegetative and reproductive adult individuals but did not differ between the last two. The bifurcation ratio did not vary during ontogenetic development. In general, allometric relationships between the stem and the crown were similar among the ontogenetic stages. Although there was a progressive increase in size during ontogenetic development, there was no change in the allometric relationships between the size variables and architecture of P. tenuinervis, indicating that the form of individuals does not change over the course of ontogeny.
