| Two islands on the continental shelf of the Colombian Caribbean. Bird observations were made during five days between 2004 and 2006 on Isla Fuerte and Isla Tortuguilla, two continental shelf islands of the Colombian Caribbean coast. On both sites 83 species were recorded. Isla Fuerte is larger and has a more complex array of habitats, supporting a larger and more complete bird community. Noteworthy species and aspects on the conservation of these insular environments are discussed. |

| Fish passages are considered the oldest management tool used to minimize the impact of blocking fish migratory routes by hydroelectric power plants. However, fish passages are being installed without specific criteria in Brazil, with severe consequences to the conservation of the local fish fauna. Therefore, basic data gathered for fish passages already constructed could contribute to define operational rules, in addition to offer subsidies to decision-making and design of future facilities. Thus, the fish ladder of Baguari Dam was evaluated regarding temporal distribution, attraction, and ascension of the local fish fauna. A total of 20 fish samples were conducted immediately downstream of the dam and inside the fish ladder, from January 2010 to June... |

| Monitoring of species and their ecosystem attributes is a fundamental requirement in applied ecology and conservation. However, landscape scale monitoring requires an immense effort and commitment, especially when species have a wide distribution or are migratory in nature. Participatory monitoring, whereby local communities are engaged, is increasingly being proposed to address landscape scale monitoring. Its implementation is met with many challenges related to finances, motivation of the local people, lack of trained manpower, and nondirect legal use of the species in question. It is of interest to determine what makes a participatory monitoring program interesting for locals to ensure their long term engagement. Using the unique 26-year program of... |

| ABSTRACT The Paraíba do Sul River is affected by extensive water collection for supply, organic and industrial pollution, and dams. Nonetheless, the ichthyofauna maintains biodiversity and sustains artisanal fisheries. This study analyzes the composition, abundance and distribution of fish larvae, an important approach to determine the reproductive period and spawning sites. The sampling occurred from August 2011 through February 2013 in five sites at a transect between the banks on the lower reach of the Paraíba do Sul River. A total of 5,412 larvae belonging to 20 taxa was captured. The predominant order was Characiformes. Larvae of Prochilodus spp. and Leporinus spp. were the most abundant; larvae of Brycon insignis, an endangered species, were present.... |
