<text><![CDATA[We measured
traits for every individual tree in nine 1-ha plots in tropical
lowland rainforest (N = 4709). Each plant was sampled for
10 functional traits related to wood and leaf morphology and
ecophysiology. Here, we contrast the trait means and variances
obtained with a full sampling strategy with those of
other sampling designs used in the recent literature, which we
obtain by simulation. We assess the differences in community-
level estimates of functional trait means and variances
among design types and sampling intensities. We then contrast
the relative costs of these designs and discuss the appropriateness
of different sampling designs and intensities for
different questions and systems.]]></text>

<text><![CDATA[With regard to estimating mean trait values, strategies
alternative to BRIDGE were consistently cost-effective. On
the other hand, strategies alternative to BRIDGE clearly
failed to accurately estimate the variance of trait values. This
indicates that in situations where accurate estimation of plotlevel
variance is desired, complete censuses are essential.]]></text>

<text><![CDATA[Here, we develop a new approach that links functional attributes
of tree species with studies of forest recovery and regional
land-use transitions (Chazdon et al. 2007). Grouping species according
to their functional attributes or demographic rates provides
insight into both applied and theoretical questions, such as selecting
species for reforestation programs, assessing ecosystem services, and
understanding community assembly processes in tropical forests
(Diaz et al. 2007, Kraft et al. 2008).]]></text>

<text><![CDATA[Falar no artigo que esse trabalho fala que é inadequada a divisão entre pioneira e não pioneira
devido a grande variação que há entre elas. Além de terem descoberto que durante a ontogenia a
resposta a luminosidade muda dentro de uma mesma espécie. Porém recomendar que essa classificação
continue sendo usada em curto prazo enquanto não há informações confiáveis suficiente para esta
simples classificação. Outras classificações como esta do artigo são bem vinda, contanto que tenham
dados confiáveis. Porém dados estáticos já são difíceis de se obter, dados temporais, como taxa de
crescimento em diâmetro ou altura, são mais difíceis ainda. Falar que vários tipos de classificações
podem ser utilizadas e quanto mais detalhe melhor, porém os dados é que são mais limitantes. Se
focarmos em dados de germinação e crescimento limitantes, como sugerem sainete e whitmore, da uma
idéia maismrápida e a curto prazo da classificação destas espécies. Depois com o tempo conseguiremos
construir classificações mais detalhadas e com mais dados confiáveis.

<text><![CDATA[Our approach avoided preconceived notions of successional
behavior or shade tolerance of tree species by developing an objective
and independent classification of functional types based on vegetation
monitoring data from permanent sample plots in mature and
secondary forests of northeastern Costa Rica (Finegan et al. 1999,
Chazdon et al. 2007).We apply an independent, prior classification
of 293 tree species from our study region into five functional types, based on two species attributes: canopy strata and diameter growth
rates for individuals Z10 cm dbh (Finegan et al. 1999, Salgado-
Negret 2007).]]></text>
