Parnaíba Basin

The Gurgueia River in southern Piauí state, Brazil, is the largest affluent on the right margin of the Parnaíba River basin. This study aimed to inventory the Gurgueia River ichthyofauna, and contribute to the knowledge of fish diversity in Northeastern Brazil. We sampled 71 locations throughout the Gurgueia sub-basin between 2006 and 2014, which resulted in 90 fish species representing 67 genera, 26 families and six orders, including two non-native species. Six species are newly recorded for the Parnaíba basin (Hasemania nana, Hemigrammus brevis, H. guyanensis, H. ora, Corydoras sp. and Cetopsorhamdia sp.), increasing its freshwater ichthyofauna to 152 species. The Gurgueia River contains 59.2% of the ichthyofauna known for the Parnaíba basin, and can be used as a reference point for the establishment of priority areas for the conservation of the freshwater fish fauna of the Brazilian Northeast.

Riverine Fish

Riverine fish in New South Wales were studied to examine longitudinal trends in species richness and to identify fish communities on a large spatial scale. Five replicate rivers of four types (montane, slopes, regulated lowland and unregulated lowland) were selected from North Coast, South Coast, Murray and Darling regions. Fishwere sampled during summer and winter in two consecutive years with standardized gear that maximized the range of species caught. The composition of fish communities varied among regions and river types, with little temporal variation. Distinct regional communities converged in montane reaches and diverged downstream. The fish fauna can be classified into North Coast, South Coast, Murray and Darling communities, with a distinct montane community at high elevations irrespective of the drainage division. Species richness increased downstream in both North Coast and South Coast regions by both replacement and the addition of new species. In contrast, species richness in the Darling and Murray regions reached a maximum in the slopes reaches and then declined, reflecting a loss of species in lowland reaches. The small number of species is typical of the freshwater fish faunas of similar climatic regions world-wide. Fish communities identified in this study form logical entities for fisheries management consistent with the ecosystem-focused, catchment-based approach to river management and water reform being adopted in Australia.

Abstract The South America ichthyofauna encompasses the highest diversity of the world, however is highly threatened by anthropogenic actions. The fish fauna of nine low-order streams, tributaries of the Piquiri River and impacted by aquaculture, agriculture and urbanization were sampled in the present study. Samplings were done quarterly from December 2017 to September 2018 at three sites in each stream, using a portable electric fishing device in 50-meter segments. A total of 14,507 individuals were collected, belonging to six orders, 20 families, 46 genera, and 70 species. The highest richness and abundance were found for the orders Characiformes and Siluriformes. In this study, nine species that had not been recorded were found, totaling 163 for the basin. In addition, 14 non-native species were captured. The presented list of species contributes to the existing database of ichthyofauna distribution in Neotropical streams, denoting that it is underestimated in the region, mainly in low-order tributaries. The present study reinforces the importance of inventories and monitoring in environments with high biodiversity and sensitive to anthropogenic actions.

Iguaçu River

Abstract The drainages of the Iguaçu River basin, as well as the main channel of the river, have peculiar characteristics resulting from geomorphological processes in this area, including the formation of the Iguaçu River Falls. This slope in the lower portion of the basin is a biogeographical barrier to many organisms. In this study was inventoried the fish fauna of streams of the lower Iguaçu River basin, evaluating possible differences in the species composition upstream and downstream of this biogeographical barrier. Sampling were conducted between 2004 and 2013, in five streams, three upstream and two downstream of the Iguaçu River Falls, using electrofishing. The nMDS analysis was run to investigate possible groupings of similar fauna between the streams sampled. The scores of this test were tested as to the significance of groupings with the Hotelling T2 test. The indicator value method (IndVal) was used to detect the distribution of species among the groups of the streams upstream and downstream of the Iguaçu River Falls. We collected 18,908 individuals of six orders, 11 families, and 40 species. Siluriformes and Characiformes had the highest species richness; Cyprinodontiformes presented the highest abundance. Considering the species recorded, 21 are considered natives to the Iguaçu River basin, including 15 endemic, wich were found only in streams upstream of the falls. Additional 18 species were verified only in the streams downstream of such barrier. Four species were common to both stretches. The axis 1 of the nMDS separated two groups: streams upstream (S1, S2 and S3) and streams downstream of the Iguaçu River Falls (S4 and S5). The indicator species analysis also indicated a distinction between the groups of streams, that were significantly different (Hotelling's T2 = 234.36, p ˂ 0.0001). The number of endemic species in the streams upstream of the Falls (15 spp.) evidences a significant effect of isolation promoted by the Iguaçu River Falls, and confirms the role of this barrier in the vicariant processes and endemism typical of this basin. These results emphasize the importance of conserving these ecosystems, once the extinction of species in this region means the irreversible loss of them.

Archeological Artifacts

Researchers associate the medieval archeological artifacts of the Middle Trans-Urals, whose pottery bears cord impressions, with the Chiyalik, Molchanvo and Yudina Cultures. Despite the large number of artifacts that have been studied, many questions remain open. These include the status, chronology, and interaction of the Molchanovo and Yudina antiquities, as well as the evolution and specifics of their pottery complexes. Publication and analysis of the ceramic collections from Vak-Kur, the largest burial ground of the Yudina Culture, contribute to addressing some problems related to «the Corded Ware cultures». The Vak-Kur burial ground is dated to the 10th–11th centuries based on the assemblage of the associated goods. It is located in the south-eastern part of the Yudina Culture areal, on the right shore of the Tobol River. For all the time of excavations in the area of the ne-cropolis, 220 burials have been studied. The dead were buried in shallow pits according to the ritual of inhuma-tion, on their backs. A specific feature of the funeral ritual is breaking of a part of the accompanying equipment and use of funerary masks. Decorative and morphological features of 143 Yudina vessels have been examined. The tableware has been categorized according to four topographic groups after excavations 3 to 6. It has been noted that, despite the similar shapes of pots, and ornamental proportions and patterns, the pottery from excava-tions 3 to 6 demonstrates a different frequency in use of such elements in the décor as the cord and figured stamps. The biggest differences were detected between the ceramic artifacts found in excavations 4 and 6. It was suggested that the differences in décor between pottery from different excavations are determined not by their asynchronous nature, but by the existence of several tribal sites in the area of the Yudina necropolis. The com-parison of ceramic collections from the Vak-Kur burial ground with those from the medieval burial and settlement sites of the Yudina Culture showed that the pottery from the necropolis is most closely related to collections from the Plamya Sibiri 6 and 7, and Antonovo 1 settlements located in the Tura River basin. These sites were dated by their investigator to the earlier period (6th to 9th centuries) and attributed to the Molchanovo Culture. Based on the significant similarity between the pottery of the named sites and the dishware of the 10th to 11th centuries from excavation 4 of the Vak-Kur burial ground, a revision of the chronology and cultural attribution of these sites has been proposed.

In the Pestan River Basin, the right tributary of the Kolubara River, a complex degradation of natural conditions has been expressed over the decades. The exploitation of lignite in the Kolubara Coal Basin, which is in large part located in the territory of this basin, as well as accompanying activities related to it, are the dominant activities that lead to the degradation of soil and hydrological conditions. If other land use types are added to this, it can be concluded that the land cover in the studied territory suffered significant negative changes. The above mentioned activities have led to land loss and deterioration of its quality, and the regulation works due to dislocation of the Kolubara watercourse into the Pestan riverbed have caused numerous degradation of landscapes, reduced the basin area and shortened its watercourse, led to morphological changes of the river network and deterioration of the surface water quality. The aim of this paper is to perform a geospatial analysis of all areas in which the degradation of soil and hydrological conditions is present, in order to prevent their further degradation and proper management of these areas.

During construction of the Furnas hydroelectric power dam in the upper rio Paraná basin in the early 1960s, the rio Piumhi drainage outflow was diverted into the headwaters of the São Francisco river basin. The rio Piumhi was a right bank tributary of the rio Grande, which unites with the rio Paranaíba to form the rio Paraná. The transposition allowed the entire fish fauna of the rio Piumhi and associated swamps, lakes, and tributaries to intermingle with the fish fauna of the São Francisco basin via the ribeirão Sujo, a right bank tributary of the São Francisco. The transposition of the watershed may have had a major impact on the current composition of the fish fauna of the upper rio São Francisco watershed.

A study on the fish assemblage of the Ipanema River, a small affluent of the Tietê River basin in southeastern Brazil, was performed aiming to look for structural patterns of species diversity in small lowland lotic environments. Fish samplings were performed every two months from June 2003 to April 2004 at four sample sites located on the lower stretch of the river. Local assemblage showed to be species rich, with fifty-two species belonging to Characiformes (25 spp.), Siluriformes (19 spp.), Cyprinodontiformes (3 spp.), Gymnotiformes (2 spp.), Perciformes (2 spp.), and Synbranchiformes (1 sp.). Fish fauna was composed of small-sized species (<200 mm SL) and by individuals of medium (up to 400 mm SL) to large (more than 400 mm SL) sized species. The Ipanema River, such as other small lotic transitional environments in the upper Paraná River drainage, is considered important for conservation of fish fauna because they cover available habitats for persistent populations of small-sized species and for non-persistent individuals or shoals of medium and large-sized fish species, which occupy other habitats along their life-history (e. g. floodplains, oxbow lakes, main channel of great rivers). The importance of the Ipanema River basin for fish fauna conservation is also reinforced by the fact that it is located in a highly impacted region of southeastern Brazil, near the São Paulo metropolitan area.
