“…Keywords: Urban trees; Diversity; Urban Forestry, Invasive trees,Resilience, Urban Planning, Tree selection Introduced tree species represent s substantial component of urban forests in cities all over the world (e.g. Cowett and Bassuk, 2014;Sjöman et al, 2012;Yang et al, 2012;Freire Moro et al, 2014). Yet there is controversy about the further use of introduced tree species.…”

“…Additional studies have shown how trees can help reduce energy use in buildings and increase thermal comfort during hot summer days (Akbari et al, 2001; Nikoofard et al, 2011; Shashua‐Bar et al, 2011; Sawka et al, 2013). In temperate climates, where the use of broadleaved trees in the urban landscape dominates (Sjöman et al, 2012; Cowett and Bassuk, 2014), the design for shade in summer and adequate solar transmission for passive heating regulation in winter is essential (Sawka et al, 2013). Although some species have a very dense make‐up of branches in winter, others present a more sparse composition in their branch architecture.…”

Branch Area Index of Solitary Trees: Understanding Its Significance in Regulating Ecosystem Services

The chief aim of this study was to investigate how different species of solitary trees in temperate urban areas vary in their branch structure during winter by assessing branch area indices (BAIs). The BAI data showed significant differences ( < 0.0001) between species and genotypes. The lowest mean BAI in the dataset was for L., which had a BAI of 0.27. L. 'Fastigiata' represented the largest mean BAI of 2.09. The results from the BAI analysis further indicate that within the same species group differences occur between genotypes. For example, the five genotypes of L. range from a mean BAI of 1.77 for 'Globosum' to a mean BAI of 0.50 for 'Fassen Black'. A further aim was to apply the compiled BAI data in the computational modeling program of ENVI-met 3.1, which simulates the surface-air interaction and microclimates in complex urban settings. The simulations focused on mean radiant temperature and wind speed. Results illustrate how wind speed on the leeward side of the trees gradually decrease with an increasing BAI. With an increasing BAI, the Tmrt decreases to the leeward of the row of trees. The results are further discussed in the perspective of sustainable urban development (i.e., where, why, and how the species studied could be integrated in the urban fabric). This is of particular interest for the design of urban green space in densely built-up urban environments where space may be restricted.

“…Para Magurran (2011), o índice de Shannon-Wiener é influenciado mais pela riqueza de espécies, entretanto um aumento no valor do índice pode ser decorrente de um aumento na riqueza de espécies, na uniformidade de composição ou de ambas as características. Cowett & Bassuk (2014) observaram acentuada correlação entre os valores de Shannon-Wiener e a riqueza de espécies e pequena correlação com a equidade de distribuição das espécies. Na Figura 2 se demonstra que o índice de ShannonWiener apresenta redução no seu valor à medida em que diminui a riqueza específica (quantidade de espécies nas amostras), sendo a sua composição influenciada de forma mais proeminente por essa componente para os dados do inventário da arborização de ruas.…”

“…Com relação às experiências de cidades brasileiras e de outros países, alguns inventários conduzidos utilizaram índices de diversidade para caracterizar a sua sensibilidade à arborização de ruas e para descrever o comportamento da composição e diversidade de espécies (Thompson et Sreetheran et al, 2011;Subburayalu & Sydnor, 2012;Cowett & Bassuk, 2014). Nas justificativas de uso ou descrições metodológicas desses índices é comum não ser informado qual o objetivo de mensuração do índice utilizado: se riqueza específica, se abundância ou se equidade, conforme as definições apresentadas por Moreno (2001) e Magurran (2011.…”

RESUMONesta pesquisa analisou-se o comportamento de índices de diversidade frente a diferentes cenários de composição com riqueza de espécies e uniformidade distintas, a influência do espaçamento de plantio na determinação dos valores desses índices e o comportamento dos dados de diversidade de um inventário da arborização em relação a dois cenários de composição aproximados aos dados reais. Constatou-se que há influência significativa do aumento do espaçamento de plantio somente para os índices de riqueza específica. Houve diferença significativa entre os valores de todos os índices para os cenários de diversidade elaborados. Nos cenários analisados, os índices de riqueza específica apresentaram valores menores e mais estáveis que os do inventário, e os índices de equidade apresentaram valores maiores.Palavras-chave: floresta urbana, silvicultura urbana, ecologia urbana, paisagismo. Diversity Indexes Performance in the Tree-lined Street Composition ABSTRACTIn this research was analyzed the performance of diversity indexes facing different scenarios of composition with distinct species richness and uniformity, the influence of planting spacing in the determination of values of these indexes and the behavior of diversity data of a street tree inventory in relation to two scenarios of composition approximated to real data. It was noted that there is significant influence of increased planting spacing only for species richness indexes. There was significant differences between values of all indexes for the diversity scenarios elaborated. In the scenarios analyzed, the species richness indexes showed lower and more stable values than inventory ones and the evenness indexes showed higher values.
