Biological and management aspects of a Caribbean mangal: West Harbour, Jamaica

Autores: Chow, Barbara A.
CHOW, Barbara A., 1997. Biological and management aspects of a Caribbean mangal: West Harbour, Jamaica. Studies Nat. Hist. Caribbean Region 73, Amsterdam, 1997: 1-22. Observations are given for the first time of West Harbour, a pristine south-coast Jamaican mangal. West Harbour is shown to be a diverse and extensive mangal (22.5 km²) with a high degree of representativeness with respect to mangrove community types. The classical mangrove zonation is evident, a fringing seaward almost mono-specific Rhizophora fronting backswamp basin Avicennia. Mangrove community types are varied; overwash, fringe, basin and scrub Rhizophora, and basin and scrub Avicennia. A broad scale survey recorded a total of 45 plant and 183 macrofaunal components of the biota which...

Overlap of eastern and western mangroves in the South-western Pacific: hybridization of all three Rhizophora (Rhizophoraceae) combinations in New Caledonia
Provedor de dados: 16
Autores: Duke, N.C.
A recent survey of mangroves in New Caledonia located 7 taxa of the genus Rhizophora – with 6 coexisting in one estuary. This is arguably the greatest concentration of co-occurring Rhizophora taxa anywhere. Two are well-known mangrove species of the Indo West Pacific, R. stylosa and R. apiculata, and another, R. samoensis resembles the widespread Atlantic East Pacific species, R. mangle. The other four are hybrid intermediates, R. × lamarckii (= R. stylosa × R. apiculata), R. × selala (= R. stylosa × R. samoensis), and two previously undescribed combinations, R. × tomlinsonii (R. apiculata × R. samoensis) and R. samoensis var. neocaledonica (= R. samoensis × R. × selala). The new entities are unknown elsewhere. While R. × tomlinsonii is considered endemic...

RESUMO - (Teores de ligninas, nitrogênio e taninos em folhas de espécies típicas de mangue). Mediram-se os teores de ligninas, N total e taninos em folhas de Avicennia schaueriana, Laguncularia racemosa e Rhizophora mangle, coletadas em manguezais de Suape, Ilha Madre de Deus (um local muito poluído na Bahía), Cananéia e duas localidades de Bertioga, uma delas fortemente impactada por descargas poluentes, na qual não se observam indivíduos de Rhizophora, e outra situada à margem desta última área. Verificou-se que as folhas de Laguncularia e Rhizophora contêm altos teores de taninos, sendo as da primeira espécie três a quatro vezes mais ricas que as da última. As folhas de Avicennia apresentaram-se desprovidas de taninos e com os mais altos teores de N. Os...

The effects of salinity on growth and survival of mangrove seedlings changes with age
Provedor de dados: 39
Autores: Kodikara,Kodikara Arachchilage Sunanda; Jayatissa,Loku Pullukuttige; Huxham,Mark; Dahdouh-Guebas,Farid; Koedam,Nico.
ABSTRACT Six wide-ranging mangrove species, Rhizophora apiculata, R. mucronata, Avicennia marina, A. officinalis, Bruguiera gymnorrhiza, and B. sexangula, were selected to study the growth and survival of seedlings under three contrasting salinity treatments over a 30-week period: low (3-5psu), moderate (15-17psu) and high (33-36psu). Seedlings grown under high salinity exhibited significantly lower performance (p&lt;0.05) in survival rates, cumulative shoot height, mean growth rates, mean total leaf area, and mean dry weight, compared to those under low and moderate salinity regimes. The low salinity treatment provided the best conditions for initial establishment and growth of the seedlings of all species until 15-20 weeks of age. However, the same...

Distribuição das espécies e estrutura do manguezal do rio Benevente, Anchieta, ES
Provedor de dados: 49
Autores: Petri,Detony José Calenzani; Bernini,Elaine; Souza,Leandro Marelli de; Rezende,Carlos Eduardo.
A estrutura da floresta de mangue do estuário do rio Benevente, Anchieta, ES foi analisada pelo método de parcelas, com o propósito de avaliar a distribuição das espécies ao longo do rio. Os resultados indicaram uma tendência de distribuição das espécies, visto que Avicennia schaueriana Stapf &amp;amp; Leechm ex Moldenke e Rhizophora mangle L. exibiram maior dominância e densidade relativa nas áreas sob maior influência marinha, enquanto que Laguncularia racemosa (L.) Gaertn.f. e Avicennia germinans (L.) Stearn. apresentaram maior densidade nas áreas sob maior influência de água doce. A densidade variou de 700 a 7.866 troncos.ha-1, a área basal de 10,3 a 72,2 m².ha-1, a altura média de 2,0 a 16,4 m e o DAP médio de 4,7 a 27,3 cm. A maioria das florestas...

Diversity of leaf endophytic fungi in mangrove plants of Northeast Brazil
Provedor de dados: 58
Autores: Costa,Isabella P. M. Wanderley; Maia,Leonor Costa; Cavalcanti,Maria Auxiliadora.
With the aim of increasing the knowledge about endophytic fungi, a group of microorganisms with high biotechnological potential and a valuable source of useful metabolites, a survey in leaves of mangrove plants (Avicennia schaueriana, Laguncularia racemosa, and Rhizophora mangle) was performed at the Itamaracá Island, PE, Brazil. Leaves were collected, during two seasons, dry and rainy, superficially sterilized and fragments maintained in Petri dishes with Potato dextrose agar (PDA) at 28º ± 2º C until isolation of the fungi. Fourty taxa were isolated: 25 species representing 19 genera and 15 morphotypes determined as Mycelia sterilia. Leaves of L. racemosa hosted the highest number of colony forming units (CFU) and taxa. Guignardia sp. and Colletotrichum...
