“…El proceso de colonización del sotobosque implica la llegada de propágulos y la existencia de condiciones aptas para la regeneración y desarrollo de las diferentes especies (Lugo 1997). Otros mecanismos de persistencia como el rebrote de raíz o el banco de semillas permitirían la presencia de especies en el sotobosque (Gachet et al 2007). Sin embargo, estos mecanismos son fuertemente influenciados por el uso previo del suelo al eliminar el banco de propágulos y generar barreras que limitan la instalación de las especies (Holz et al 2009).…”

Efecto de variables de paisaje y de rodal sobre la diversidad de especies arbóreas en el sotobosque de plantaciones de Pinus taeda en la provincia de Misiones, Argentina A total of 91 native tree species were found in the forest understory, and the most abundant were animal-dispersed tree species. The native tree composition of plantations understory was different from that of native forest. The similarity analysis revealed that old plantations were more similar to native forest than to young plantations. The canonical correspondence analysis (CCA) showed that previous land use was the variable with more influence on the understory composition, followed by the basal area and the distance to the native forest at the time of planting. Wind-dispersed and pioneer species were more associated with short distances to the native forest and lower basal area; whereas animal-dispersed and shade tolerant species were related to high basal area and previous land use.Results support the idea that forest plantations may represent a suitable environment for the development of native plants.

“…Except for studies dealing with vegetation competition, very few studies have been conducted on understory development in North American plantations. Most studies on North American understory flora in plantations have been conducted in boreal forests and only account for conifer plantations (Swindel and Grosenbaugh, 1988;Ramovs and Roberts, 2005;Newmaster et al, 2006;Gachet et al, 2007). These studies observed a generally low abundance and diversity of native forest herbs in plantations.…”

Plant functional types Understory floraVertical structure A B S T R A C TWith an increasing proportion of natural forests being replaced by plantations, there is a need to determine their potential to fulfill ecological purposes other than wood production.This study evaluated the extent to which deciduous and coniferous plantations develop understory attributes comparable to those of naturally regenerated stands. A functional group approach was used to synthesise species responses in terms of their ecological traits.Multivariate analyses of ecological traits revealed 16 emergent groups that shared common traits associated with a similar life history strategy. Responses of these groups, understory structure, and understory environmental conditions to plantation types and stand stages were analyzed and compared to naturally regenerated stands. Clear associations of trait responses to stand developmental stages and plantation types emerged. Light-demanding and wind-dispersed species groups were associated with early-successional stages, while woody groups, ferns and ant-dispersed spring-flowering herbs were associated with latesuccessional stages. Analyses also revealed an indicator group associated with old naturally regenerated forest. The understory functional groups and environmental conditions of deciduous plantations converged toward those of old naturally regenerated forests. However, understory structure in deciduous plantations remained poorly developed and richness of the indicator group was low compared to unplanted stands. Conifer plantations, currently the most common plantation type in the northern hardwood biome, showed a completely different pathway of understory development. Modifications to current plantation management practices are proposed to help recreate or maintain natural understory biological and physical attributes.

“…Algumas métricas da paisagem foram utilizadas com sucesso para prever fatores socioeconômicos e indicar impactos das atividades humanas no padrão da cobertura do solo (GHAFOURI et al, 2016). Outros estudos também tratam de como o uso da terra e as mudanças na paisagem afetam a biodiversidade (GACHET et al, 2007;MENDENHALL et al, 2016).…”

ResumoEste trabalho teve como objetivo caracterizar a bacia hidrográfica do rio Iraí por meio de indicadores métricos da paisagem. A bacia do rio Iraí está localizada na região metropolitana de Curitiba (PR) e compreende uma área de 11.178 hectares nos municípios de Pinhais, Piraquara, Quatro Barras, Campina Grande do Sul e Colombo. O mapeamento da cobertura do solo da bacia, realizado no ano 2000, com escala de 1:20.000, foi utilizado para calcular indicadores de borda, área, forma, área central e agregação. A cobertura com campo, juntamente com as outras duas classes de vegetação natural, arbórea e arbustiva, representam 68,9 % da cobertura do solo, enquanto as classes associadas principalmente às transformações antrópicas da cobertura do solo somam 31,1%. Os campos se apresentaram como a matriz da paisagem, pela dominância de área e maior conectividade. A cobertura arbórea natural foi bastante expressiva com uma área de 1.886 ha em fragmentos maiores de 100 ha, o que mostra dados favoráveis para a conservação de espécies raras e ameaçadas de extinção que requerem maiores extensões de área. Com a descrição dos indicadores da paisagem foi possível comparar os padrões das classes de cobertura do solo e disponibilizar uma fonte de informação para tomadores de decisão e para monitoramento ambiental da bacia, bem como para auxiliar na definição de pesquisas mais específicas.

Abstract Landscape indexes in Iraí river basin in metropolitan region of Curitiba (PR).This study aimed to characterize the landscape of Iraí River hydrographic basin through metric landscape indicators. The Iraí River hydrographic basin is located in metropolitan region of Curitiba (capital of Paraná State) and covers an area of 11,178 hectares in the municipalities of Pinhais, Piraquara, Quatro Barras, Campina Grande do Sul and Colombo. The land cover mapping of the basin, made in the year 2000, with the scale of 1:20,000, was used to calculate edge metrics, area, shape, central area and clumpiness. The coverage with grassland, together with the other two classes of natural vegetation, arboreal and shrub, represent 68,9% of the soil coverage, while the classes associated mainly to the anthropic transformations of the soil coverage amount to 31,1%. The grassland presented as a matrix, due the dominance of area and greater connectivity. The natural tree cover was significant and appeared well maintained, with an area of 1,886 hectares in remaining forest over 100 ha, showing favorable for the conservation of rare and endangered species that require larger areas. With the description of landscape metric indicators, it was possible to compare the patterns of land cover classes and provide a source of information for decision makers and for environmental monitoring of the hydrographic basin, and for defining more specific researches.
