To better understand the fish fauna of Amazonian streams, we assessed small streams in a landscape of forest fragments and savannah in the region of the lower Tapajós River, Brazil. We sampled the fish fauna using a well-tested active capture method during two dry seasons (October 2006 and 2018) and one rainy season (March to May 2018). Species richness was calculated using an abundance matrix and first-order jackknife estimator. Using qualitative and quantitative data, we present a cluster analysis in which each stream corresponds to a sampling unit. We collected 6,094 individuals of 43 species distributed in six orders. The sampling effort represents 73% of the estimated richness (58.69 ± 7.65). The most abundant species were Copella nattereri, Iguanodectes variatus and Laimosemion dibaphus that together represent almost half of the total sample (48.7%). The most frequent species were Aequidens epae, Helogenes marmoratus and Laimosemion dibaphus, which were collected in 11 of the 13 sampled streams. This is the first fish fauna list for small-order streams of savannah and forest fragments landscape in Amazonian Brazil. The richness of fish and the presence of many rare species underscore the contribution of small streams to the regional fish fauna composition, even in dynamic and spatially restricted landscapes.

Since the period of the military dictatorship in Brazil, Amazon has become the focus through public and credit policies to privilege the interests of capital over traditional people (riverine people, fishermen, quilombolas, indigenous people), secular settled population, and other subjects (landless workers, those settled in agrarian reform projects). They are forcibly deterritorialized in this logic of integration of national and international capital in the exploration and production of commodities in this space. This paper aims to portray the recent perspective of the last two decades of territorialization process of international interest, with the inflow of large capital resources, such as mining and hydroelectric energy production. The methodology used was the case study, with interviews, documentary, and bibliography research. These enterprises, of great magnitude of socio-territorial transformations, tend to provoke a new process of deterritorialization of hundreds of families of rural workers, as in the case of those settled in agrarian reform projects, riverine people, quilombolas and indigenous people.

Focusing the observation in the North region of Brazil, especially at the university campus of Bragança of Eastern Amazon, this article proposes to present an inventory of the institutional insertion of Ancient History, indicating the characteristics and the main challenges for the structuring of the field in the region, from my experience as a teacher and researcher in the area.

The article describes the new specie Alpaida (A.) guto from the State of Pará, Brazil. The species is said to be abundant in Caxiuanã National Forest, eastern Amazonia. The male A. guto has eyes that are ringed in black, a sternum that is yellowish with a median black longitudinal line and a yellow abdomen with two lateral pairs of black patches and posterior black mark. The female A. guto has the same color as the male except for the presence of white patches in the dorsum of the abdomen, between the two lateral pairs of black patches and posterior black mark.
