Taquara River is situated in an agriculturist region, on the northern portion of the Tibagi river basin, state of Paraná. Fish fauna was collected in five stretches of the Taquara River and in nine headwaters of its tributaries, in the period of May to December 2006. Six orders, 22 families, and 74 species were collected, in a sum of 2,389 individuals. The orders Characiformes and Siluriformes were dominant.

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.

We report the rediscovery of Pithecia vanzolinii in the upper Juruá River Basin, in the State of Acre, Brazil. An individual was collected after being hunted by a local inhabitant of an extractive community in the Riozinho da Liberdade Extractive Reserve. This is the first record of this species in the last 60 years and highlights the importance of intensifying studies of this almost unknown species.

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.

RESUMO The permanence of a plant species in a forest community depends on its number of specimens and its distribution in the various sizes of individuals, including seedlings. Seedlings and seeds from a forest remnant in Pirassununga were collected and analyzed for the degree of threat, possible height of the adult individual, occurrence in phytophysiognomies and region and morphological aspects. 116 seedlings available in 39 morphospecies were collected, and the germination of collected seeds provided 40 species. The present study brought news regarding the morphological aspects, the identification and the distribution of seedlings of tree species in a riparian forest area in the Mogi Guaçu River Basin and in the State of São Paulo.

The De Rossett Farm and Quate Place sites were among the earliest East Texas archaeological sites to be investigated by professional archaeologists at The University of Texas (UT), which began under the direction of Dr. J. E. Pearce between 1918-1920. According to Pearce, UT began work in this part of the state under the auspices of the Bureau of American Ethnology, and that work “had led me to suppose that I should find this part of the State rich in archeological material of a high order.” The two sites were investigated in August 1920. They are on Cobb Creek, a small and eastward-flowing tributary to the Neches River, nor far to the northeast of the town of Frankston, Texas; the sites are across the valley from each other. The De Rossett Farm site is on an upland slope on the north side of the valley, while the Quate Place site is on an upland slope on the south side of the Cobb Creek valley, about 2 km west of the Neches River, and slightly southeast from the De Rossett Farm. Both sites have domestic Caddo archaeological deposits, and there was an ancestral Caddo cemetery of an unknown extent and character at the De Rossett Farm.

AbstractThe Peregrine Falco peregrinus, is an Nearctic migrant to Brazil where its status in central Brazil is still poorly known. Herein we present a compilation of records of the species from the state of Tocantins and comment on its use of a wintering site in the state of Goiás. These records show that the Tocantins-Araguaia River Basin is a migration route for the species, and therefore a mid-continental migration route through the interior of South America.

This work intends to examine if there are associations between fish species and the state of conservation of the riparian forest in the Corumbataí River Basin. Four main rivers were chosen for this study with three sites on each. Collections were carried out from March to June and from September to December 2001. Multivariate techniques were applied to determine the correlation between species richness and the order of the rivers, preservation level of the riparian forest, shade level, presence or absence of Eucalyptus, sugar cane and pastures, and surrounding declivity stability of the sites. Species richness was highest at locations with greater vegetation cover and preserved riparian forest.

Abstract Most native Amazonian crops were domesticated in the periphery of the basin. The upper Madeira River basin is an important part of this periphery where several important crops were domesticated and others are suspected to have been domesticated or arrived early. Some of these crops have been reasonably well studied, such as manioc, peanut, peach palm, coca and tobacco, while others are not as well known, such as the hot peppers Capsicum baccatum and C. frutescens, and still others need confirmation, such as cocoyam and annatto. We review the information available for manioc, peach palm, Capsicum, peanut, annatto and cocoyam. The state-of-the-art for Capsicum frutescens, annatto and cocoyam is insufficient to conclude definitively that they were domesticated in the upper Madeira, while all the others have at least one of their origins or centers of diversity in the upper Madeira.
