“…This leads to micro-and macro-climate change, which, combined with previous environmental changes, exacerbates the proliferation of infectious parasitic diseases for humans (Alves and Souza 2011;Cunha 2008;Guerra and Carvalho 1995;Sanches and Fisch 2005). In addition, silting and sedimentation in the soil due to the construction of the dams have affected the water quality of the region of the enterprise, increasing the eutrophication phenomenon, damaging the fauna and the aquatic flora of the reservoir and, with this, the quality of the water of this region, which may constitute not only an environmental and economic problem but also a public health one (Carneiro and Rubin, 2007).…”

-(Lycophytes and monilophytes from Unidades de Conservação da Usina Hidroelétrica -UHE Tucuruí, Pará, Brazil). This work presents a survey of lycophytes and monilophytes in the Conservation Unit named Zonas de Preservação da Vida Silvestre da Usina Hidrelétrica de Tucuruí, Pará State, Brazil. This Conservation Unit is located at southeastern Pará and comprises about 29,700 ha, composed mainly of tropical rainforest. Our results recorded 18 families, 37 genera and 82 species. The richest family is Pteridaceae, with 21 species, and Adiantum is the richest genus, with 14 species. Three species are new records for Pará State: Didymoglossum ovale, Danaea nodosa, and Pecluma hygrometrica. Furthermore, two new species were identified. One has already been described, Thyelypteris amazonica. The other new species belongs to the genus Adiantum and shall be published soon. The floristic richness of the area, associated with the taxonomic novelties, attests for its biological importance and for the necessity of increasing the efforts on research and conservation of the study area.

O presente estudo refere-se às espécies de licófitas e monilófitas ocorrentes nas Zonas de Preservação da Vida Silvestre da Usina Hidroelétrica de Tucuruí, Estado do Pará, Brasil. A área de estudo localiza-se na região sudeste do Pará, com cerca de 29.700 hectares, composta, predominantemente, por floresta ombrófila aberta. Os dados obtidos demonstraram a ocorrência de 18 famílias, 37 gêneros e 82 espécies. A família com maior riqueza de espécies é Pteridaceae (21 spp.) e o gênero mais representativo é Adiantum com 14 espécies. Três espécies são novas referências para o Pará: Didymoglossum ovale, Danaea nodosa e Pecluma hygrometrica. Além disso, duas espécies novas foram identificados, uma delas já descrita, Thyelypteris amazonica. A outra espécie pertence a Adiantum e será publicada em breve. A riqueza florística da área, associada com as novidades taxonômicas, atesta a sua importância biológica e aponta para a necessidade de aumentar os esforços em pesquisa e conservação da área estudada.

One of the most common types of polyspecific association observed in Neotropical primate communities is that between squirrel monkeys (Saimiri) and capuchins (Cebus). The present study focused on association patterns in two Saimiri sciureus groups in eastern Brazilian Amazonia, between March and October, 2009. The associations were analyzed in terms of the species involved, the degree of association, and niche breadth and overlap. The study involved two S. sciureus groups (B4 and GI) on the right and left bank of the Tocantins River, respectively, within the area of the Tucuruí reservoir in southeastern Pará. Relations between species were classified as associations (individuals within 50 m and moving in the same direction), and encounters (individuals within 50 m and no coordinated movement). Group B4 was in association with Cebus apella during 100% of monitoring, and with Chiropotes satanas in 20.2%. By contrast, Group GI associated with Cebus 54.8% of the time, and with Chiropotes utahickae 2.5%. Encounters with Alouatta belzebul and Saguinus niger were recorded at both sites, with Aotus azarae and Dasyprocta prymnolopha at B4, and with Callicebus moloch, Dasyproct aleporina, Mazama gouazoubira, and Nasua nasua at GI. Overall, Saimiri had a broader niche than Cebus in terms of vertical spacing and diet, but not for substrate use. This pattern did not appear to be affected by association. While group GI spent significantly (P < 0.05) more time in association with Cebus during the wet season, group B4 associated with Chiropotes more during the dry season. Despite the higher association rates, niche overlap was greater for all variables at B4. This may reflect differences in the ranging and foraging patterns at the two sites, and the varying potential benefits of association for Saimiri.
