“…In this region, Spartina alterniflora marshes usually colonize mud flats or tidal creeks as narrow discontinuous belts in front of mangrove woodlands. Seasonal variation in standing crop and productivity of local saltmarshes have been studied in this area by Adaime (1978), Panitz (1987), Soriano-Sierra (1990) and Lana et al (1991).…”

Structure and temporal variability of macrobenthic associations at vegetated and unvegetated sites of a Spartina alterniflora marsh were analyzed over a 14 mo period in the euhaline, highenergy sector of Paranagua Bay (southeastern Brazil). The vegetated site was characterized by significantly higher numbers of species, mean densities and faunal dominance. T h e presence of plant cover affects epifaunal grazers, such as the gastropods Nentina virginea, Littorina flava and the isopod Sphaeromopsis mourei, besides a number of infaunal dominants associated with the root-rhizome mat, such as the polychaetes Isolda pulchella and N e r e~s ollgohalina Seasonal patterns of change were evident at both sites, with higher macrofaunal densities coinciding seasonally with higher availability of plant litter and lower predation pressure. Macrobenthic populations were generally more persistent at the vegetated site, despite short-term or seasonal vanations. At the unvegetated site, intense and unpredictable population shifts were exhibited by the numerical dominants Kalljapseudes schubarti and Corophium acherusicum. Differences in trophic organization were also evident, with a marked dominance of suspension-feeders at the unvegetated site. Our results suggest that (1) much of the spatial and temporal structure of macrobenthic associations in euhaline, high-energy flats of a subtropical estuary depends on the presence of plant cover, together with seasonal fluctuations in detrital input and predation pressure, and (2) knowledge of the interaction between plant cover and time is a prerequisite for useful data interpretation or hypotheses formulation In such environments.

BOOTH, T. 1983. Lignicolous marine fungi from Slo Paulo, Brazil. Can. J. Bot. 61: 488-506.Lignicolous substrates, i.e., wood and leaves, were collected from 10 Slo Paulo State locations and 2 Pernambuco State sites. These were subsequently surveyed and incubated and (or) washed, macerated, and plated on culture media. Six types of wood and mangrove leaves were placed in exposed and buried digestors, recovered, surveyed, incubated, and resurveyed for marine fungi. Of a total of 69 isolated taxa, 32 species, including 24 ascomycetes, seven fungi imperfecti, and one basidiomycete, are discussed. , and ecological considerations are presented for each species. A possible Scolecobasidium-Septoria-Mycosphaerella anamorphic-teleomorphic association is suggested. BOOTH, T. 1983. Lignicolous marine fungi from S5o Paulo, Brazil. Can. J.

“…Foram registradas variações na produção em relação à altura das 3 formas consideradas. Há, contudo, opiniões divergentes quanto a essas diferenças, sendo estas atribuídas a fatores genéticos ou a fatores ambientais (Adaime, 1978).…”

“…A densidade geralmente teve uma correlação negativa com a altura média de cada campo, ou seja, quando a densidade é menor, observa-se uma estatura maior das gramíneas. A produção anual de Spartina por metro quadrado está correlacionada com a altura que as plantas atingem na maturidade, sugerindo assim que a produção de Spartina possa ser realizada meramente pela determinação da distribuição de freqüência de sua altura no outono, porém Adaime (1978) encontrou, durante toda a época de coleta, grande número de plantas novas, provavelmente oriundas da reprodução vegetativa de seus rizomas. De certa forma, a medição de altura é válida como uma forma indireta de avaliar a produção da gramínea, visto que durante todo o ano (Adaime, op.…”

“…Dessa forma, no presente trabalho foi realizada a medição do comprimento dos indivíduos como forma indireta de avaliar a produção vegetal. Considerando que a S. alterniflora apresenta diversidade morfométrica, sendo conhecidas três formas: anã, média e alta, na área PA, Adaime (1978) encontrou apenas um tipo de S. alterniflora, cuja altura máxima foi de 130 cm.…”
