The northern coast of Brazil has more than 30 estuaries distributed along 650 km of coastline. These conditions favor the presence of relatively large fish communities in estuarine environments, but published information on the fish fauna in tidal creeks in northern Brazil is only available for some mangrove systems, and comparative studies between fish estuarine communities in different tidal creeks are less common. The choice of the study area was based on the fact that it has been poorly investigated with regard to estuarine fish fauna in comparison in mangrove tidal creeks using the same fishing gear. The objective of the present study was to compare the composition of the relative biomass of taxonomic, functional and ecological guilds of fish assemblages occurring in estuarine systems along the northern coast of Brazil. The study area of the present comparative analysis extended from the southeastern edge of the Marajoara Gulf to the western edge of the Maranhense Gulf. A comparative analysis among different estuarine systems was performed using data from other studies. The abundance of juveniles was greater in the Caeté, Curuçá and Cururuca estuaries than other estuaries. Cluster analysis separated the estuaries into two distinct groups and significant differences between these groups only exist in relation to geographical proximity. The present investigation indicates that the coastal region between the states of Pará and Maranhão is characterized by high dynamics and environmental heterogeneity, particularly with regard to changes in river discharge and tidal fluctuations. The present results underscore the importance of ecological information on ichthyofauna in tropical estuaries in order to include appropriate descriptors in conservation or restoration processes of marine communities and habitats.

AbstractThis article analyzes the restoration of Jordan's UN Dana Biosphere Reserve cottages for ecotourism and home building in the neighboring village of Qadisiyya as competing land projects. Whereas a multimillion-dollar endowment from the United States Agency for International Development (USAID) restores Dana's houses as a “heritage” village for a tourist economy, families in Qadisiyya build houses with income from provisional labor to shore up a familial future. Each act of home building articulates a political claim to land. This article argues for attention to the architecture of the environment in the comparison of two, once-related villages. A comparative analysis of Dana and Qadisiyya reveals the competing socio-political objectives of home building for the future of Jordan and the implications of environment in that struggle.

The paper deals the complex research of the biota xylotrophic ascomycetous fungi of forest ecosystems of the the seven of natural reserve funds of Ukrainian Carpathians: NNP "Synevyr", Carpathian NNP, NNP " Hutsul’shchyna", Uzhansky NNP, NNP "Skolivski Beskydy" , and Carpathian Biosphere Reserve and Nature Reserve " Gorgany" is represented. A taxonomic composition and comparative analysis of ecological and biological features of the ascomycetous fungi is determined. In total 406 taxa 389 in the rank species were recordered for the investigated region. All found species representing 190 genera, 66 families, 26 orders, 10 subclasses, 6 classes, subphylum Pezizomycotina, that belong phylum Ascomycota, and also anamorphic fungi incertae sedis Pezizomycotina.

The United Nations Educational Scientific and Cultural Organization has designated the Man and Biosphere Program to foster a better relationship between the environment and people. The topic of this study is to elucidate the role of local communities in the regional development of Biosphere Reserves with a focus on management roles (top-down or participatory) and the motivational drivers of the people involved (ecocentric or anthropocentric). Based on qualitative interviews taken from the two case studies of the Mount Hakusan Biosphere Reserve in Japan and the Katunskiy Biosphere Reserve in Russia, a comparative analysis was conducted to explore the differences between the engagement of locals in the management of their biosphere reserves. This analysis examined relationships between the government and the local communities, the attitudes of the locals towards the biosphere reserves, and the historical perception on nature protection for each community. The findings showed that Russian biosphere reserves are mainly managed by local people who live inside the protected area while Japanese biosphere reserves are governed by local authorities and administration offices. This allows the Russian communities to have greater access to management processes, and therefore play a larger role in regional development.
