In the red list of threatened species of Pará State, in Brazil, the salamander Bolitoglossa paraensis was listed as vulnerable. Initially the species was considered a synonym with Bolitoglossa altamazonica, but was recently revalidated. This note discusses the validity of the specimens from the west of the Brazilian Amazon identified as B. paraensis. It is also discussed the categorization of the species as vulnerable, and the records of the species was mapped in the Endemism area Belém. In order to establish a Private Natural Reserve (RPPN), a herpetological survey was carried out in different landscape units of the Nova Amafrutas, in Benevides (Pará), and the records of B. paraensis were mapped in these landscape units. By comparing the abundances recorded by Crump (1971) and those results of the present study, suggested that this species is tolerant to antropic “capoeira” forest (old fallows) next to undisturbed forest. More molecular phylogeographic studies are needed in order to establish a stable the taxonomy status for B. paraensis, and also the definition of its real endemic status in the Center of Endemism of Belém.

The Anapa bay-bar is located in the northwestern part of the Black Sea. With the goal in mind to determine the short-term dynamics of the Anapa bay-bar we analyzed satellite images from 2003 to the present. Depending on the hydro-lithodynamical situation the shoreline configuration during storm can vary from a rectilinear to sinusoidal forms. There are regions of local erosion or accumulation whose formation is related to the alongshore motion of sediments and dynamics of underwater bars. Comparison of the data on 1965 and 1966 showed that in this period the amplitude of the shoreline position was more than 20 m but average displacement of the shoreline for 13 months was only 0.8 m. This study showed that for the analysis of changes in the shoreline position is necessary to consider the configuration of the coastline at the time of each observation and the local dynamics.

Sustainable development is among the foremost ideas that guide societal aspirations around the world. This book interrogates the concept through a critical lens, examining both its history and the trajectory of its manifestations in the Brazilian Amazon. The book argues that sustainable development is a concept that is better understood as involving embroilments and ongoing processes of contestation rather than a single end goal. The research offers historical analysis of Amazonian development from the colonial era into the discourse and praxis of sustainable development in contemporary times, and then illustrates the tensions of sustainable development plans that are experienced by people living in the areas geographically the closest to where those plans are being implemented. The history of the Brazilian Amazon is introduced to readers through focused discussions on the tensions between making grand plans for the region and the everyday practices and experiences of sustainable development, which involve considerably more muddling. Case studies explore agrarian reform initiatives that occur alongside road paving projects, the creation of extractive reserves and conservation areas that follow in the wake of assassinations, and the construction of a massive hydroelectric dam. While Amazonian sustainable development is a widely-accepted imperative, the research presented here shows how land use and infrastructure plans conducted in the name of sustainable development often perpetuate and reinforce economic and political inequalities.
