A three-year mark-recapture study in a remnant population of Crocodylus acutus Cuvier in Portete Bay (Guajira, Colombia) Gayana
Espinosa,Mara I; Bertin,Angéline; Gómez,John; Mejía,Florencio; Guerra,Martha; Baez,Lina; Gouin,Nicolas; Patiño,Edgar.
The American crocodile, Crocodylus acutus, has experienced important population declines worldwide due to human persecution, overexploitation and habitat loss. C. acutus remains critically endangered in some countries such as Colombia where the lack of detailed surveys on its ecology and distribution constitutes a major barrier to the development of effective conservation strategies. We conducted a three-year capture-recapture study to investigate the demographic status of C. acutus and to identify environmental variables likely to in uence its distribution in Portete Bay (Colombia). We estimated the crocodile population to be relatively small (< 140 animals), to include very few adults, and to demonstrate a very strong de cit in females in the juvenile...

Hostim-Silva,Maurício; Ribeiro,Gisela Costa; Clezar,Leandro; Ledo,Blanca Sierra de.
Attempting to contribute with the knowledge about the bioecological aspects concerning the youth forms of M. furnieri (Desmarest, 1823) and C. leiarchus (Cuvier, 1830) from Itacorubi mangrove, 15 samplings were taken from January 1988 to March 1989. Using casting and entangle nets, a total of 308 individuais from these species were captured. Their abundanee were: M. furnieri N = 197 (64,0%); C. leiarchus N = 111 (36,0%). The relative frequency and range of total weights and lengths were studied. Concerning spatial distribution of the species, it was observed that M. furnieri occurred in all areas and C. leiarchus was not captured only in "D" area (Sertão River). During the anual cycle the two species occurred jointly. The results emphasize other authors...

Aspectos da reprodução do caranguejo guaiamum, Cardisoma guanhumi Latreille (Crustácea, Decapoda, Gecarcinidae) da Baía de Sepetiba, Rio de Janeiro, Brasil Zoologia
Silva,Rejane da; Oshiro,Lídia Miyako Yoshii.
The objective of this work is to get knowledge about the "guaiamum" crabs reproduction. Two hundred and twenty four crabs were caught from August'96 to July'97. Their sex carapace color and morphometric data were obtained. The stages of gonadal development were macroscopically determined and the eggs diameter was measured. Three colors patters for the carapace for males, and four patters for females. Five stages of gonadal development were observed in female crabs, and two stages were observed for males. The first sexual maturity was estimated 53,0 mm carapace width for the females and 52,0 mm for the males. The ovigerous females occurred from March to May. The individual fecundity varied from 103.300 to 366.400 eggs. The eggs mean diameter was 0,39 mm.

Aspectos nutricionais na vegetação de manguezal do estuário do Rio Mucuri, Bahia, Brasil Rev. Bras. Bot.
CUZZUOL,GERALDO ROGÉRIO FAUSTINI; CAMPOS,ANDRÉA.
A existência de zonas monoespecíficas é característica no manguezal do rio Mucuri, BA, onde Laguncularia racemosa L. e Rhizophora mangle L. ocupam locais sob maior influência da maré e Avicennia germinans L. está restrita a locais de salinidade mais baixa. A vegetação neste manguezal é classificada em bosques ribeirinhos (margem do rio) e bosques de bacia (interior). Parâmetros físicos e químicos do sedimento e suas relações com a concentração dos nutrientes foliares foram associados à distribuição das espécies estudadas. Os resultados mostraram que A. germinans dominou sítios com menores valores de pH, de salinidade, de carga de troca catiônica e de silte e alto teor de argila, quando comparada às outras duas espécies estudadas. O substrato de R. mangle...

Biodiversité et dynamique des peuplements ichtyiques de la mangrove de Guaratuba, Brésil ArchiMer
Chaves, P; Bouchereau, Jl.
The Bay of Guaratuba, whose area is approximately 45 km(2), is a basin, situated to the south of Brazil (25 degrees 52' S; 48 degrees 39' W) and connected to the Atlantic ocean. In its northern part, a region of mangrove is found, under the influence of seasonal fluvial contributions, dominated by Laguncularia racemosa. The depth exceeds 6 m in some places. According to the period of the year, salinity varies between 3 and 37, and temperature between 15 and 28 degrees C. Several of the present fish species are exploited by commercial and recreational fisheries. This work describes characteristics of the fish populations occupying this mangrove, and temporal and spatial evolution of populations of the main species from available data on their biology....

Biomonitoring of Heavy Metals (Fe, Zn, Cu, Mn, Cd and Cr) in Oysters: Crassostrea rhizophorae of Mangrove Areas of Alagoas (Brazil) BABT
Azevedo,Joaquim Alexandre Moreira; Barros,Alexandre Bomfim; Miranda,Paulo Rogério Barbosa de; Costa,João Gomes da; Nascimento,Velber Xavier.
Abstract Mangroves are tropical and subtropical flooded forests that generally develop in estuarine areas over unstable sediments protected from the action of waves in the intertidal zone with an environment characterized by a great diversity of fauna and flora. Thus, the present study aimed to evaluate the levels of heavy metals that are absorbed by mangrove oysters, in estuarine systems in the Alagoas coast by determining the concentrations of Fe, Cu, Mn, Zn, Cd and Cr. Two areas, which consisted of both a collection during the rainy season and the dry season, were selected for sampling of mangrove oysters. In each collection, seven samples were collected, at seven different points, where each sample contained four oysters. In the laboratory the oysters...

Bruguiera (Rhizophoraceae) in the Indo-West Pacific: a morphometric assessment of hybridization within single-flowered taxa Naturalis
Duke, N.C.; Ge, X.-J..
The first putative hybrid tree species of the genus Bruguiera (Rhizophoraceae), B. × rhynchopetala, is reported from mangrove forests of China and Australia. It was described from China previously as a variety of B. sexangula. The hybrid is acknowledged as B. gymnorhiza × B. sexangula with parent species restricted to different parts of the Indo-West Pacific. The hybrid is recognised at north-eastern and south-eastern parts of the overlap area between parent distributions, but it appears absent in western parts. Further local assessments are needed across the range. Hybrid status is supported by: 1) intermediate and shared morphological characters; 2) distribution limited to areas of co-occurrence of B. gymnorhiza and B. sexangula; and 3) molecular...

Capture techniques' use of Caranguejo-uçá crabs (Ucides cordatus) in Paraíba state (northeastern Brazil) and its socio-environmental implications Anais da ABC (AABC)
Nascimento,Douglas M.; Ferreira,Emmanoela N.; Bezerra,Dandara M.M.S.Q.; Rocha,Pollyana D.; Alves,Rômulo R.N.; Mourão,José S..
The present study was undertaken in two traditional communities that are located on the margins of the estuary and mangrove complex of the Mamanguape River, Paraíba state (PB), Brazil. This work describes the crabs capture techniques tapamento and redinha, and identifies the negative socio-environmental impacts of redinha, using qualitative methods (open and semi-structured interviews, guided tours, direct observation and the administration of questionnaires). Results indicate that currently only two principle techniques are used to capture Ucides cordatus: redinha and tapamento. Tapamento has a low impact in relation to redinha. Redinha was pointed out by interviewees as a system that has social impact (social conflicts, breaking of traditions,...

Cartographie des biocénoses marines de Guadeloupe à partir de données SPOT (récifs coralliens, phanérogames marines, mangroves) ArchiMer
Chauvaud, S; Bouchon, C; Maniere, R.
In the framework of a comprehensive study of the coastal marine ecosystems of Guadeloupe Island (French West Indies), a remote sensing survey of marine communities was conducted in the Bay of the Grand Cul-de-Sac Marin. Pictures of SPOT satellite were used. At first sight, XS data from SPOT did not seem to be well adapted to extract information from deepest underwater areas. In the present study, a method for analysis of XS data was developed, which increases tenuous spectral differences associated to very low intensity signals. This technique led to a better distinction of objects, even the deepest ones. Reference surfaces were then identified in the field and a reliable supervised classification was conducted, which reflected the high diversity of...

Chemical and microbiological characterization of mangrove sediments after a large oil-spill in Guanabara Bay - RJ - Brazil BJM
Maciel-Souza,Maria do Carmo; Macrae,Andrew; Volpon,Antonia Garcia Torres; Ferreira,Patrícia Silva; Mendonça-Hagler,Leda Cristina.
Seventeen months after a 1,3 million L oil spill into Guanabara Bay, analyses of mangrove sediments showed that the three sites closest to the spill remain highly polluted (>10 µg-g-1 polyaromatic hydrocarbons). A fourth site was less polluted, from which most hydrocarbon degrading bacteria were isolated.

Composição ictiofaunística da área de manguezal da Baía de Guaratuba, Paraná, Brasil Zoologia
Chaves,Paulo de Tarso da Cunha; Corrêa,Marco Fábio Maia.
The Guaratuba Bay (25o52'S, 48o39'W) is the second largest estuarine system of the State of Parana, Brazil. It extended inside of the continent for about 15 km and is surrounded by mangroves. Water depth can reach up to six meters. The fish faunal composition of this area was evaluated with a bottom trawl and, occasionally, casting and gill nets. One species of Chondrichthyes and 59 of the Actinopterygii (50 genera and 28 families) were reported from the Bay. The results were not significantly different from those of the Paranagua Bay, except by the lower number of species. These differences appear related to distinct collection efforts and the extension of surveyed areas. No species can be considered endemic to the region. Tipically freshwater species...

Concentrations and fractionation of carbon, iron, sulfur, nitrogen and phosphorus in mangrove sediments along an intertidal gradient (semi-arid climate, New Caledonia) ArchiMer
Deborde, Jonathan; Marchand, Cyril; Molnar, Nathalie; Della Patrona, Luc; Meziane, Tarik.
In mangrove ecosystems, strong reciprocal interactions exist between plant and substrate. Under semi-arid climate, Rhizophora spp. are usually predominant, colonizing the seashore, and Avicennia marina develops at the edge of salt-flats, which is the highest zone in the intertidal range. Along this zonation, distribution and speciation of C, Fe, S, N, and P in sediments and pore-waters were investigated. From the land-side to the sea-side of the mangrove, sediments were characterized by I/ increase in: (i) water content; (ii) TOC; (iii) mangrove-derived OM; II/ and decrease in: (i) salinity; (ii) redox; (iii) pH; (iv) solid Fe and solid P. Beneath Avicennia and Rhizophora, TS accumulated at depth, probably as a result of reduction of iron oxides and...

PINHEIRO,MARCELO A.A.; SOUZA,MARCELO R.; SANTOS,LUCIANA C.M.; FONTES,ROBERTO F.C..
ABSTRACT Ucides cordatus is a relevant fishery resource of Brazilian mangroves and requires legal normative to sustainable use based on stock assessment and management. This study evaluated some population parameters (structure, density, abundance, fishery potential and stock) of this crab species in Brazil Southeast (São Paulo, State), discussing the use of the results to delineate fishery management strategies. Density was monthly evaluated (September 1998 to August 1999), using five sample quadrats of 2x2 m. Density (ind.m-2) was indirectly estimated by counting the opened (with biogenic activity) and closed galleries, and contrasted with flooding level by tides using the vertical distribution of macroalgae in the base of trees. Density of U. cordatus...

Martins,Salise Brandt; Marochi,Murilo Zanetti; Masunari,Setuko.
ABSTRACT The first stage of the fiddler crab Minuca mordax is described here. Zoea larvae obtained from four ovigerous female were reared in the laboratory until the development of the first crab stage. The development from zoea I to the first juvenile instar lasted 35 days after hatching. The first crab stage of Minuca mordax can be morphologically distinguished from those of Minuca burgersi and Leptuca cumulanta by a 2-segmented antennule endopod (3-segmented in M. burgersi, unsegmented in L. cumulanta), an unsegmented maxillule endopod (2-segmented in M. burgersi and L. cumulanta), and a 4-segmented first and second maxilliped endopod (respectively unsegmented and 5-segmented in M. burgersi and L. cumulanta). The three species have the following...
