          Abstract

          Abstract Home gardens have considerable biodiversity conservation potential. However, these spaces are unplanned, and there is little information about the flora diversity in the backyards of different social classes. The current study has quantified and compared plant diversity in the backyards of two neighborhoods located in the metropolitan region of Maringá - RMM (Paraná, Brazil), namely, Conjunto Triangulo and Zona 02. The diversity patterns were markedly different when the neighborhoods were compared. Therefore the present study has set some planning guidelines aiming at increasing the presence of woody vegetation, as well as at contributing to biodiversity conservation, including the conservation of endangered plant species, in the backyards of the RMM.

          Resumen Patios tienen un potencial considerable para la conservación de la biodiversidad. Sin embargo, estos espacios no son planificados, y existe poca información sobre la diversidad de la flora presente en los patios de las diferentes clases sociales. Hemos cuantificado y comparado la diversidad vegetal de los patios de dos barrios de la región metropolitana de Maringá (Paraná, Brasil), a saber, el Conjunto Triangulo y la Zona 02 mediante la identificación de las especies y a través del cálculo de índices de diversidad, correlaciones bivariadas y del potencial de plantíos. Los estándares de diversidad son acentuadamente diferentes, cuando comparados los barrios, y por ello hemos trazado algunas directrices de planificación, con el objetivo de aumentar la presencia de la vegetación arbórea, y contribuir a la conservación de la diversidad biológica, incluyéndose la conservación de las especies de plantas en peligro de extinción, en los patios de la RMM.

          Resumo Quintais urbanos possuem um considerável potencial para a conservação da biodiversidade. Não obstante, esses espaços são pouco planificados, e há pouca informação sobre a diversidade da flora presente nos quintais de distintas classes sociais. Quantificamos e comparamos a diversidade vegetal dos quintais de dois bairros da Região Metropolitana de Maringá, (Paraná, Brasil), a saber, Conjunto Triangulo e Zona 02. Os padrões de diversidade são distintos, pelo que esboçamos algumas diretrizes de planejamento, com o objetivo de incrementar a presença de vegetação arbórea, reforçar a segurança alimentar e contribuir para a conservação da diversidade biológica, incluindo-se a preservação de espécies vegetais ameaçadas de extinção.

              Socioeconomics drive urban plant diversity.

              Spatial variation in plant diversity has been attributed to heterogeneity in resource availability for many ecosystems. However, urbanization has resulted in entire landscapes that are now occupied by plant communities wholly created by humans, in which diversity may reflect social, economic, and cultural influences in addition to those recognized by traditional ecological theory. Here we use data from a probability-based survey to explore the variation in plant diversity across a large metropolitan area using spatial statistical analyses that incorporate biotic, abiotic, and human variables. Our prediction for the city was that land use, along with distance from urban center, would replace the dominantly geomorphic controls on spatial variation in plant diversity in the surrounding undeveloped Sonoran desert. However, in addition to elevation and current and former land use, family income and housing age best explained the observed variation in plant diversity across the city. We conclude that a functional relationship, which we term the "luxury effect," may link human resource abundance (wealth) and plant diversity in urban ecosystems. This connection may be influenced by education, institutional control, and culture, and merits further study.
