Abstract: RESUMO -(Variação temporal de características morfológicas de folhas em dez espécies do Parque Nacional da Restinga de Jurubatiba, Macaé, RJ, Brasil). Ordenar espécies em relação a um contínuo de variação de características foliares pode ser útil para inferir sobre a suscetibilidade de uma comunidade a alterações na disponibilidade de recursos e/ou condições ambientais ao longo do tempo. Dez espécies lenhosas de restinga foram acompanhadas quanto à variação temporal de atributos morfológicos foliares. Folhas d… Show more

“…In addition, some species have a lower amount of leaf area available for transpiration during the dry season (Rosado and de Mattos 2010). In terms of leaf morphological traits, Rosado and de Mattos (2007) also reported in the same restinga species, a trend of highest values of LMA, SUC, TH and DEN in dry months during three years of study suggesting convergent responses to deal with temporal heterogeneity of water availability. Additionally, in a broad scale, the study of Huxman et al (2004) also observed that despite differences across biomes in annual precipitation, physiognomy and climatic history, rain use efficiency (i.e., the ratio of aboveground net primary production to precipitation) converged during years when water was the most liming factor.…”

“…The Clusia scrub assemblage is characterized by areas of bare sand and vegetation thickets having woody shrubs with broad leaves and the C 3 photosynthetic pathway with the exception of Clusia hilariana (Clusiaceae). The most common species found in these thickets (Araujo et al 2004) We used the mean values from the dataset obtained by Rosado and de Mattos (2007) from nine measurements made from February of 2003 to August of 2005 (three per year) for the above species at this site. To measure the above parameters, ten leaves from separate individuals of each species were collected on the north side of their respective canopies.…”

“…Such environments display many geomorphological formations, invariably with low availability of resources, mainly due to the low capacity of retention of water and nutrients in sandy soils. (Rosado and De Mattos 2007). The estimative for the Brazilian restinga vegetation is more than 4,000 species, only to Rio de Janeiro state, 1,005 species have already been registered (Sá 2014, Araujo 1992.…”

“…2), são poucas as espécies que apresentam condições adaptativas para colonizar e formar densos agrupamentos sobre elas. Adaptações estruturais e fisiológicas são fundamentais para a manutenção dessas populações e várias são reportadas na literatura, como suculência, pubescência, hábito prostrado, metabolismo CAM, órgãos de reserva, polinização e dispersão pelo vento, entre outros (García-Mora et al 1999, Boeger & Gluzezak 2006, Rosado & Mattos 2007. Uma vez estabelecidas as populações fixadoras de dunas, o ambiente torna-se mais propício para a colonização de novas espécies, permitindo assim um aumento na riqueza específica (Almeida & Araújo, 1997).…”
