On many websites, there is a channel to report inappropriate content.

Vegetal fibers, also called lignocellulosic fibers, are basically composed by lignin, hemicellulose and cellulose, and the amount, morphology and how these constituents are found in the fibers depend on many factors.

Thus the study of lignocellulosic fiber reinforced polymer composite focus on understanding the properties of composites according to fiber properties, taking into account parameters such as, the type of fiber reinforcement and matrix content, fiber surface treatments and processing conditions. Depending on the type of polymer matrix, thermoplastic or thermoset, a single fiber may also have a different effect on the final properties of the composites. This study showed therefore a summary of the main results obtained in recent studies using natural composite.

However, some species reported exclusively in the Imboassica Lagoon are typical inhabitants of continental coastal environments, and they might also occur in the comparatively less studied lagoons of the Restinga de Jurubatiba National Park. That is possibly the case of the ophichthids Myrophis punctatus and Ophichthus cylindroideus.

Three species, in particular, are also relatively common in environments similar to the lagoons of the Restinga de Jurubatiba National Park, and therefore their occurrence in the Park is highly probable: Eighty-one species of fishes were recorded in the lagoons and pools of the Restinga de Jurubatiba National Park.

Those species belong to 18 orders and 34 families of the Teleostei.

When only the fishes recorded in the Jurubatiba National Park are considered, families with the largest number of species are the Carangidae nine speciesEngraulidae eight speciesGobiidae seven speciesCharacidae six speciesGerreidae five speciesand the Clupeidae, Poeciliidae, and Cichlidae each with three species. All other families are represented by only one or two species. Fifty-seven of all fishes recorded in the lagoons of the Restinga de Jurubatiba National Park were regarded as Residents.

When only Resident species are considered, families with the largest number of species are the Gobiidae seven speciesCharacidae six speciesGerreidae five speciesand the Poeciliidae and Cichlidae each with three species. The other 19 families with Resident species recorded in the lagoons of the Restinga de Jurubatiba National Park are represented by one or two species. Seventy species of fishes, including Resident and Occasional, were recorded in the Carapebus Lagoon.

As an anecdotal comparison that illustrates the relatively high fish diversity found in the Restinga de Jurubatiba National Park, the number of species found in the Carapebus Lagoon alone is equivalent to about one-third of all known freshwater fishes of Australia e. The Carapebus Lagoon also has the largest number of species that were exclusively recorded in a single lagoon of the Park. With the exception of one species, all the eight species exclusively recorded in the Carapebus Lagoon are marine and relatively common in the region, and were regarded as Occasional.

These species are the anchovies Anchoa januaria, A. Two other resident species of the Carapebus Lagoon are the non-native pacu-peva Metynnis maculatus and the African tilapia, Tilapia rendalli.

The other lagoons of the Park included in this study have less than ten recorded species. As the sampling effort was unequal among lagoons, those numbers are merely descriptive and might underestimate the presumed diversity of at least some lagoons. Three species, for instance, were exclusively recorded in freshwater pools Pools in Table 1adjacent to the Piripiri and Catingosa lagoons.

One of them is the Near Threatened Atlantirivulus jurubatibensis, which up to this day is the only known endemic species of fish recorded in the Restinga de Jurubatiba National Park.

Species richness and possible correlations with area and salinity The local richness of species is typically higher in Orthogonal lagoons among the lagoons studied Table 2. An analysis of the specific composition of the Resident species excluding those found exclusively in the pools revealed a strong pattern of segregation of the lagoons.

Vegetal fibers in polymeric composites: a review

Two larger clusters are recognizable in the space between the two axes of the CA: A small group of fishes composed by Phalloptychus januarius, Jenynsia multidentata, Brachyhypopomus janeiroensis, Poecilia vivipara, Atherinella brasiliensis and Tilapia rendalli influenced the ordination of the Parallel lagoons and the Preta Lagoon, which are more similar among themselves in terms of fish composition when compared to the Orthogonal lagoons.

Orthogonal lagoons also share a higher number of Resident species, with values ranging between 8 and However, the co-occurrence of species is not pronounced among Orthogonal lagoons, a condition which determined a higher dispersion of those lagoons along the first two axes of the CA.

This result is mostly influenced by the species exclusively recorded in the Imboassica Lagoon, such as Ctenogobius shufeldti, C. Marine species and species of the Secondary Division were more frequent in Orthogonal and Parallel lagoons, respectively. Summing up, Parallel and Orthogonal lagoons are significantly different in terms of the composition of Resident species according to the CA Figure 2C.

Typically in moderately sized lagoons, with less than 2 km2, fishes of the Secondary Division account for at least half of their total species richness. A correlation between the area of the lagoons and the ratio of species of the Primary or Secondary Divisions, or marine fishes, was also not found Figure 3. However, a positive correlation between the ratio of species of the Secondary Division and the salinity was found in the analysis. This result highlights the relevance of those species to the composition of the fish community in lagoons with a low richness.

Fishes of the Primary Division were only marginally correlated with the salinity, in a negative correlation. Interestingly, the proportion of marine species was not correlated with the salinity of the lagoons Figure 2.

Discussion The total richness of fish species of the Restinga de Jurubatiba National Park is approximately two times higher than indicated in previous studies e. A more refined knowledge of the diversity of these lagoons clearly reflects the intensity with which they have been studied in the last decade, particularly after the onset of the "PELD, Site 5".

A large portion of the continental species of fishes whose occurrences in the region are expected according to their currently known geographic distributions have been actually recorded in this study. We suspect, therefore, that future sampling efforts will mostly result in the documentation of Occasional marine species in the lagoons of the Restinga de Jurubatiba National Park. However, additional, yet unrecorded, Resident fishes might inhabit the relatively less explored lagoons of the Park, such as the Preta, Piripiri, Visgueiro and Catingosa.

That is possibly the case of the fat sleeper Dormitator maculatus Eleotridaewhich has been collected in other lagoons of the northern Rio de Janeiro State e. The idea that the Jurubatiba National Park might still harbor some rare species of fishes is evidenced by two small pools identified as Pools in Table 1 associated to the Piripiri and Catingosa lagoons, which only recently were sampled.

The eventual addition of this "hidden diversity" to the list of species of the Park would not substantially modify the total number of recorded species, but would certainly be relevant in terms of conservation in view of their rarity and possible endemism. Two introduced species have been recorded in the lagoons of the Restinga de Jurubatiba National Park. One of them is the pacu-peva Metynnis maculatus, whose occurrence in the Park is herein reported for the first time.

We suppose instead that M. The occurrence of pacu-pevas in other lagoons of the Park and the possible effects of their introduction into these ecosystems should be monitored in future studies.

Another introduced species recorded in several lagoons of the Restinga de Jurubatiba National Park and the Imboassica Lagoon is the African tilapia, Tilapia rendalli. That species is frequently caught in moderate to high quantities, and seems to be well established in the Park. The guppy Poecilia reticulata, recorded in the Imboassica Lagoon only among the lagoons studied, is widely regarded as an easily adaptable exotic species. Their occurrence in the Imboassica Lagoon indicates that the species is likely to succeed in the lagoons of the Park in the case of one or more events of introduction.

It is also possible that guppies are already inhabiting the less explored lagoons or pools inside the Park, especially those with moderate to higher levels of salinity. That species is extremely resilient, occurring in several different habitats, especially in lentic environments similar to those of the Jurubatiba National Park. Clarias gariepinnus is a generalist predator that can reach up to cm TL Teugels, The species is also able to naturally disperse through land between closely located water bodies or during flood events.

The introduction of C. The relatively high number of typically marine species recorded in the lagoons of the Restinga de Jurubatiba National Park and the Imboassica Lagoon clearly indicates that their fish fauna communities are largely influenced by the sea. Some Resident species of marine fishes, such as Atherinella brasiliensis and the species of Centropomus, Diapterus, Eucinostomus, and Mugil, are apparently spending their whole life cycles in lagoons where salinity levels are relatively high.

However, other marine species regarded as Residents and Occasional enter the lagoons probably through a combination of two different processes, whose relative influences to the fish composition probably vary according to the orientation of the lagoons. In Orthogonal lagoons, we suspect that the intrusion of marine species is mostly related to events of sandbar breaching. Those events naturally occur in several lagoons of the region, and are artificially induced in the Imboassica Lagoon and, less frequently, in the Carapebus and Paulista lagoons.

In Parallel lagoons, sandbar breaching is less frequent or practically inexistent in the recent geological history. However, marine species might be able to penetrate those lagoons during events of extremely high and strong tides, when sea waves are known to overcome the sandbars, carrying larvae and juveniles into the lagoons.

The high frequency of occurrence of those events in the lagoons of the region probably explain why a correlation between levels of salinity and presence of marine fishes or of fishes of the Primary Division of Myers was not found. A combination of those events, sandbar breaching and intrusion of larvae and juveniles during extreme high and strong tides, is also probably correlated with the higher number of Occasional species found in Orthogonal lagoons.

Those factors together might also contribute to the higher number of species recorded in them, even though a correlation between the area alone and species richness was not supported according to our results.

A higher similarity in terms of species composition among Parallel lagoons, when compared to Orthogonal ones, was also observed. This result might reflects the lower number of species recorded in the Parallel lagoons in comparison to the Orthogonal ones, which are more influenced by the sea in terms of species composition. However, other minor channels that connect the distal opposite to the sea portion of the Parallel lagoons might also help to explain why their fish communities seem to be more similar when compared to Orthogonal lagoons.

Floods in strong rainy season, which are relatively common in the region, might also sporadically connect the Parallel lagoons, promoting a higher similarity among their fish communities. Identification key of Resident species recorded in the Imboassica Lagoon and in the Restinga de Jurubatiba National Park The identification key below includes 57 Resident species of fishes recorded in the Imboassica Lagoon and the Restinga de Jurubatiba National Park.

As in all regional keys, we strongly recommend that this key be used with caution. Table 1 lists all species of fishes that have been so far recorded in the Imboassica Lagoon and the Restinga de Jurubatiba National Park, including 43 that were regarded as Occasional and, consequently, are not included in the key. The species composition of those lagoons is largely influenced by the sea, with the consequence that some yet unrecorded stenotopic or euryhaline marine species might be occasionally collected.

A single species of silverside, Atherinella brasiliensis Atheriniformes: Atherinopsidae was recorded in our study, but a morphologically similar species, A.

Another species of silverside, Odontesthes argentinensis, was recorded only recently in the region Di Dario et al. Those species have not yet been collected in the lagoons of the Restinga de Jurubatiba National Park or in the Imboassica Lagoon, but their occurrence in those water bodies should not be disregarded.
