“…Definitions vary in breadth and are especially challenging for variable taxa and those which hybridise. The appropriate inclusion of ecology, though long debated, remains unresolved (Andersson 1990;Grant 1992;Pendry et al 2007). For most taxonomists, species "can be characterized as hypotheses" which may be falsified (Knapp 2008).…”

We reply to Webber et al. (2011). Our study, Sheil and Padmanaba (2011), was a preliminary assessment of the alien Neotropical tree Cecropia around Bogor, West Java, Indonesia. We highlighted the need for low-cost assessment approaches for addressing alien species and considered what might be achieved by local actors with limited resources. We successfully characterised the local distribution of Cecropia and identified, addressed and illustrated various concerns. Based on these results we asked how such studies might be useful and how they could be improved. Webber et al. criticise our study but fail to engage with its goals. Certainly, low-input local approaches lack the sophistication and rigour of larger international efforts, but such comparisons are unhelpful. Aside from a number of misunderstandings, we find Webber et al.'s principal arguments overstated, and unsupported by published information. The evidence that Cecropia causes harm is unconvincing; species-level identification is overemphasised; and the insistence on completing detailed research before considering management options is problematic. We offer some positive conclusions and repeat our plea for the development of effective low-input methods for evaluating and addressing naturalised organisms.

“…However, plants have many attributes that may be used for identifying functional groups (Pendry et al, 2007) and the choice of such attributes must be clearly related to the role played by the species within the ecosystem. In this study, we focus on attributes that may represent the impacts caused by the presence of a dam.…”

Dams are important to human wellbeing; however, they can cause various environmental changes. In the cerrado stricto sensu, waters from the reservoir modify water supply in the soil and can affect species establishment. It is argued that species adapted to high water availability can establish close to river banks and water reservoirs and their characteristics are different from those of species from the cerrado stricto sensu. These characteristics could be more similar to those of species from riparian forests, with higher values of height and basal area. Thus, we aim to analyze changes in an area of the cerrado stricto sensu, 35 years after the construction of a hydroelectric dam. We tested different parameters to determine these changes, including richness, diversity, individual height and basal area (using the square-point method), with individuals <1 m, individuals >1 m, and Bromeliaceae (using the plot method) in three sectors close to the artificial lakeshore (0 m -20 m, 40 m -60 m, and 80 m -100 m away from the water). Using species diversity, we also compared the species functional group within these sectors. Sectors closer to the dam acted as an edge, presenting lower basal area and individual's height, but species with different traits compared to those of a cerrado stricto sensu area.Keywords: biomass accumulation, cerrado stricto sensu, tree community, hydroelectric energy, phytosociology, functional groups, functional traits. resumoRepresas são importantes para o bem-estar humano, no entanto, podem causar diversas alterações nos ambientes. No cerrado stricto sensu, as águas represadas modificam o abastecimento de água no solo e podem alterar o estabelecimento das espécies. Argumenta-se que as espécies adaptadas à alta disponibilidade de água podem estabelecer-se próximo às margens de rios e reservatórios e possuem características distintas daquelas de espécies de cerrado stricto sensu. As características seriam mais semelhantes àquelas de espécies de matas ciliares, com elevada estatura e área basal. Assim, almejamos analisar as mudanças em uma área de cerrado stricto sensu após 35 anos sob a influência de uma usina hidrelétrica. Testamos parâmetros distintos para determinar essas mudanças, tais como a riqueza, a diversidade, altura dos indivíduos e área basal (utilizando o método do ponto quadrante), com indivíduos < 1 m, indivíduos > 1 m e Bromeliaceae (utilizando o método de parcelas) em três setores próximo à margem da represa (a 0 m -20 m, 40 m -60 m e 80 m -100 m da represa). Utilizando a diversidade de espécies, também comparamos os grupos funcionais de espécies nesses setores. Os setores mais próximos à represa possuíam baixa área basal e altura dos indivíduos atuando como uma borda, mas com espécies com diferentes características em relação ao cerrado stricto sensu.Palavras chave: acumulação de biomassa, cerrado stricto sensu, comunidade arbórea, energia hidroelétrica, fitossociologia, grupos funcionais, traços funcionais. 64Vale et al.

“…A good example is the way in which plant physiology, with its high dependence on sophisticated instrumentation, has been integrated into the study of rain forest dynamics and diversity (e.g. Meir et al 2007 and references therein). Evolutionary and genetic studies provide another area that has seen a major growth recently (e.g.…”

“…The opening paper is a tribute to John Proctor, made in the form of the description of a new Lobelia species, named in his honour (Argent et al 2007). A presentation follows on ways to increase the usefulness of taxonomic and ecological specimen collections by making information available in databases that are structured in line with the needs of the different user groups (Pendry et al 2007). A study by Lemes et al (2007) introduces the breeding system of mahogany (Swietenia macrophylla King) against the backdrop of forest fragmentation in Amazonia.…”
