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>

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

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

<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.

behavior or shade tolerance of tree species by developing an objective

monitoring data from permanent sample plots in mature and

secondary forests of northeastern Costa Rica (Finegan et al. 1999,

rates for individuals Z10 cm dbh (Finegan et al. 1999, Salgado-
