Medium, minimum population doubling time 1. In the United States, more than obsolete dams have been removed and rivers reconnected over the last 40 years O’Connor et al.

Articles with ‘species’ microformats. Retrieved from ” https: Proc Natl Acad Sci Studies have investigated the composition of the parasite fauna of this fish in Brazilian rivers Feltran et al.

These events may dramatically alter the way the ecosystem behaves and are mirrored by changes in the diversity of wildlife communities and their parasite populations.

This characteristic has also been noted for several other teleost species Narahara et al. An analysis of similarity ANOSIM using the Jaccard index qualitative and the Bray-Curtis index quantitative was performed with 10, permutations to test the null hypothesis of no difference in the composition and abundance of the parasite community of L.

The reproductive success of a species is a limiting condition for its maintenance and exploitation in the new environment.

In dry season, they are confined to the deepest parts of the river where they are captured with fishing rods. Services on Demand Journal. Maximum Standard Length — mm.

Females spawn aroundtoeggs Ref. Anostomidaefrom the Orinoco Basin, Venezuela. This might be explained by three suppositions: This condition has been commonly observed for other fish species Santos et al.

Paleontological Leporijus software package for education and data analysis. Nevertheless, the same pattern could not be demonstrated in Itaipu, that is the variations in the physical condition of the species could not be attributed to changes in the breeding season, but coincided only with the spawning sites, possibly reflecting the availability of food in the environment.

In Itaipu, following a gradual reduction leporinuss size, an increase and stabilization in mean length at first gonadal maturation were observed in the last three years studied years 6, 7, and Mechanisms of species coexistence: Among these, Monogenea was the most ffiderici and prevalent taxonomic group from all the sampled areas. The relationship between the duration of the breeding season and the reproductive intensity values of mean GSR was also notable: Information from such studies may also be useful in evaluating the evolutionary pattern and the ecological relationships which make it possible for a species to survive in these environments.

Leporinuss were made monthly in both the pre-closure Frderici and the post-closure September August phases. While the Jurumirim Dam area of influence has monthly variations in rainfall and water levels, the hydroelectric power station is responsible for major spatial and temporal unpredictability Garcia-Mellado et al.

Estimators of species richness provided roughly similar results with the observed values exhibiting a satisfactory level of sampling effort Figure 4. The fish fauna in the fish passage at the Ourinhos Dam, Paranapanema River. Reproduction takes place from November to June, with a peak from December to March but mature individuals can be found year round.

The degradation and homogenization of natural habitats is considered a major cause of biotic homogenization. Considering the biotic homogenization effect of dams, the present study hypothesizes that the Jurumirim Dam homogenizes the parasitic fauna of L. Ecology leporiuns the parasites of freshwater fishes.
