Abstract: in "restingas", because favorable microhábitats have patchy distribution, and due to the high vegetative reproduction rate in bromeliads, we tested the hypothesis that the pattern of spatial distribution of bromeliads in a "restinga" habitat would be aggregated. we used the "restinga" of the parque nacional da restinga de jurubatiba as our hypothesis test area. we analyzed the spatial distribution pattern of each studied species using morisita dispersion index (id). we found 10 bromeliad species, with 10179 individuals in the 0,98 ha sampled. in the study area, nine species had an aggregated distribution pattern (id > 1). we suggest that the aggregated distribution pattern of bromeliads may be explained by the rate of vegetative reproduction, distribution of the favorable abiotic conditions and availability substrates in clumps, which occur in patches in the study area, favoring the bromeliads occurrence.

Abstract: this work aimed to investigate the composition, abundance and some behavioral aspects of phytophagous species associated with "murici da praia", byrsonima sericea (malpighiaceae), in the national park of restinga de jurubatiba, rio de janeiro state, brazil. during 14 months, from april 2003 to may 2004, bimonthly surveys were conducted on 120 plants, while observations on b. sericea insects were made since november 2000. an overall of 45 associated insect species were found, being 20 exophytic lepidopteran caterpillars, 17 exophytic coleoptera, four leaf miners and four galling species. lius sp. (buprestidae), a leaf miner beetle, was the most abundant and frequent species, followed by the caterpillar gonioterma indecora (elachistidae). a comparison between lepidopteran caterpillars on b. sericea in the restinga and other byrsonima species of the cerrado vegetation showed low insect similarities between these and b. sericea, which also had the lowest species richness. both caterpillars and leaf miners abundance peaked between june and august, prior to the leaf flush, while the abundance of exophytic coleoptera immatures increased simultaneously with leaf production. possible explanations for the temporal distribution patterns of insects on b. sericea are discussed and a brief description of the ecological aspects is given for the main identified phytophagous insect species.

Abstract: long term ecological research (lter) site no.5 in the restinga de jurubatiba national park, northern rio de janeiro state protects a region rich in habitats and flora. we describe the variation in flora and structure of the herbaceous layer of the open clusia scrub formation at three different sites near two coastal lagoons. all herb layer plants were sampled at each site in 200 1x1m quadrats (total: 600m2); number of plants and percent cover were recorded in each quadrat. these sites were compared as to similarity (s?rensen), diversity (shannon: h') and evenness (j'). a total of 3,021 plants were sampled in 39 species, allagoptera arenaria (gomes) kuntze, vriesea neoglutinosa mez, aechmea nudicaulis (l.) griseb., stigmaphyllon paralias a. juss., neoregelia cruenta (graham) l.b. sm., anthurium maricense nadruz & mayo, pilosocereus arrabidae (lem.) byles & g.d. rowl. and ipomoea imperati (vahl) griseb. had the highest importance values. the diversity index was h' = 1.89 nats/m2 (j' = 0.52) based on plant cover in order to avoid having to determine what constituted an individual and because this parameter represented the oligarchic structure more precisely. site a is significantly different from sites b and c in number of individuals and herbaceous cover, but not in number of species and diversity indices. our results differ in part from those observed previously for the shrub layer, thus indicating a need for studies on spatial distribution and species associations in order to clarify the relationship between these two strata.

Abstract: the aim of this study was to perform a list of bat species captured in six lagoons in the parque nacional da restinga de jurubatiba, rio de janeiro state, brazil. the park is located about 180 km eastward of rio de janeiro city and covers the municipalities of macaé, carapebus and quissam?. the region is dominated by sand dunes and sand ridges formed in the quaternary. we captured 149 bats belonging to three families and 14 species. most species caught in restinga de jurubatiba were frugivores, partly due to technique employed, mist-net, that favors the capture of individuals of the phyllostomidae family. five species are uncommonly captured in bats inventories (uroderma magnirostrum, lasiurus cinereus, lophostoma brasiliense, chiroderma villosum and diaemus youngi). species caught varied among lagoons, showing the importance of these habitats for maintaining the diversity of bats.

Abstract: we investigated the diet and foraging of the endemic teiid lizard cnemidophorus littoralis in a restinga habitat in jurubatiba, macaé - rj. the stomach contents were removed, analyzed and identified to the order level. there was no relationship between c. littoralis morphological variables and number, length or volume of preys. termites (48.7%) and larvae (35.5%) were the most important prey items which occurred in the examined lizards′ stomachs. the diet did not differ between males and females. cnemidophorus littoralis is an active forager and predominantly consumes relatively sedentary prey or prey that is aggregated in the environment. we also found an intact and undigested hatchling of the crepuscular/nocturnal gekkonid lizard hemidactylus mabouia in the stomach of an adult male of c. littoralis, which indicates that c. littoralis is a potential source of mortality for individuals of h. mabouia in the restinga de jurubatiba.

Abstract: Bromeliaceae is one of the most representative plant families in restinga habitats. We analyzed the speciesrichness and composition of Bromeliaceae in 13 restinga habitats along the Brazilian coast. We found a total of 41species distributed along the restinga habitats studied. The restinga of Praia do Sul, in the state of Rio de Janeiro, hadthe highest number of species (15), whereas the restinga of Abaeté, in the state of Bahia, had the lowest (4). Our dataare suggestive that the Doce River may represent the limit of distribution for some bromeliad species, with some speciesoccurring only south of that river and others occurring only to the north of it. The differences in Bromeliaceae speciescomposition among restinga habitats probably are not only due to differences in local environmental conditions, butalso due to the geographic distribution pattern of each species and to the present degree of disturbance at each restinga.

Abstract: studies on anurans in restinga habitats are few and, as a result, there is little information on which methods are more efficient for sampling them in this environment. ten methods are usually used for sampling anuran communities in tropical and sub-tropical areas. in this study we evaluate which methods are more appropriate for this purpose in the restinga environment of parque nacional da restinga de jurubatiba. we analyzed six methods among those usually used for anuran samplings. for each method, we recorded the total amount of time spent (in min.), the number of researchers involved, and the number of species captured. we calculated a capture efficiency index (time necessary for a researcher to capture an individual frog) in order to make comparable the data obtained. of the methods analyzed, the species inventory (9.7 min/searcher /ind.- msi; richness = 6; abundance = 23) and the breeding site survey (9.5 msi; richness = 4; abundance = 22) were the most efficient. the visual encounter inventory (45.0 msi) and patch sampling (65.0 msi) methods were of comparatively lower efficiency restinga, whereas the plot sampling and the pit-fall traps with drift-fence methods resulted in no frog capture. we conclude that there is a considerable difference in efficiency of methods used in the restinga environment and that the complete species inventory method is highly efficient for sampling frogs in the restinga studied and may be so in other restinga environments. methods that are usually efficient in forested areas seem to be of little value in open restinga habitats.

Abstract: we present a synthesis of the bryophyte flora in restinga de jurubatiba national park, based on field work, herbaria material and bibliography. sixty one taxa were recorded, in 15 families and 33 genera. for each taxa, we analyze geographic distribution, substrata and life form. the most species-rich family was lejeuneaceae (25 species), followed by jubulaceae (seven), calymperaceae (four) and sphagnaceae (four). most taxa have a neotropical (35%) distribution, and most taxa prefer the corticicolous substrate. mat was the most common life form. the bryoflora of this national park is an important reservoir of bryophyte diversity in the restingas, with 45% of the taxa known from the sandy coastal plains of brazil and 82% known from the this habitat in rio de janeiro state. a key to identification of the species is given.
