| Phylogeographic studies are currently used to infer historical demographic processes such as gene fow, determination of effective population sizes, colonisation dynamics, and population botlenecks, as well as for the determination of species boundaries and the identification of possible conservation units. We present a review of the main contributions of this approach, and its applications and implications for canid conservation. Studies performed in canids have shown that the number of named subspecies is often larger than that of phylogeographic units. In recent times, the fragmentation of habitats has increased and one of the major concerns of conservation biologists is the occurrence of inbreeding. Large-sized canids have demonstrated to have enough... |

| O presente estudo teve por objetivo analisar o comportamento da Fórmula de Monte Alegre (FMA) e quantificar os focos de calor detectados por satélites de referência, comparando os mesmos com os incêndios ocorridos no Parque Nacional da Chapada dos Guimarães de 2007 a 2015. O monitoramento dos focos de calor foi realizado através de imagens dos satélites AQUA, TERRA e NOAA, cujos dados diários de focos detectados foram usados para compor a série temporal ao longo dos anos, permitindo a análise de tendências dos números de focos para o parque. Os dados foram adquiridos na plataforma do Instituto Nacional de Pesquisas Espaciais, na base de dados históricos do Instituto Nacional de Meteorologia e junto à gerência do parque. Na maioria dos anos houve uma... |

| Abstract The state of Rio Grande do Norte is considered a data gap for bat species records in Brazil. The state is also currently target of large economic projects with potential impacts on bats, especially wind farms and mining enterprises. In addition, Rio Grande do Norte has few conservation units in which there is no systematic study on bat fauna. The Nísia Floresta National Forest (NFNF), a federally protected area of 174 hectares, is located in the eastern coast of Rio Grande do Norte and corresponds to one of the last remnants of Atlantic Forest in the state, in its northernmost limits. A bat inventory was conducted in NFNF using mist nets set at ground level, from sunset to sunrise, from December 2011 to December 2012, totaling 25 sampling nights.... |

| Over 70% of threatened birds in the state of Rio Grande do Sul, south Brazil, inhabit forest environments. The creation and maintenance of protected areas is one of the most important measures aiming to mitigate these problems. However, the knowledge of the local biodiversity is essential so that these areas can effectively preserve the natural resources. Between 2004 and 2009 we sampled the avifauna in two conservation units in Rio Grande do Sul: Floresta Nacional de Canela (FNC) and Parque Natural Municipal da Ronda (PMR), both representative of the Mixed Humid Forest (Araucaria Forest). A total of 224 species was recorded, 116 at FNC and 201 at PMR, ten of which threatened regionally: Pseudastur polionotus, Odontophorus capueira, Patagioenas... |

| Conservation Units (CU) aim to contribute to the balance between human and environmental demand, by protecting natural resources and biological communities. In this study we examined the differences in the attributes of the fish community in four stretches of an urban stream, two inside and two outside the CU, without vegetation cover, and tested the hypothesis that the presence of riparian vegetation is positively reflected in the attributes of fish fauna. Five species were caught, distributed into four orders and five families. Attributes like richness, abundance, dominance, Shannon-Wiener diversity, and evenness were estimated and significant differences were detected for continuous stretches considering stream flow direction. The first stretches (URBI... |

| Predation on an adult male black capuchin monkey, Cebus nigritus (Goldfuss, 1809) by two domestic dogs was observed in the Parque Estadual Serra do Brigadeiro, in the Atlantic Forest of southeastern Minas Gerais. Predation occurred in an area of well preserved native forest 800 m from the nearest forest edge. This is the first confirmed record of predation by domestic dogs in this reserve, yet data from a study in the same area indicates that the domestic dog is the most frequently recorded mammal species, which suggests that it is common in the area. The few published reports indicate that this problem occurs in other conservation units in Brazil and should, therefore, be treated with more rigor by the environmental agencies. |

| Although the rio Capivari basin is recognized as an area of great importance for the ichthyofauna, it lacks virtually every basic requirement for the definition of appropriate conservation strategies, since not even its species composition is known. The objective of this work is to determine the composition and distribution of fish species in the upper rio Capivari basin, relating them to the local physical features, and to evaluate the effectiveness of proposed conservations units, delimited based on areas of native vegetation remains, on the conservation of local ichthyofauna. During 2007, 50 different watercourses were sampled with gillnets, cast nets and kick nets. A total of 1308 individuals belonging to 41 species were captured. Degree of... |

| We herein report tick (Acari: Ixodidae) infestation of four domestic dogs wandering inside Serra de Caldas Novas State Park, Goiás. Twenty seven ticks were collected from these hosts along nine days in November 2008. Ticks were identified as adults of Amblyomma cajennense, Amblyomma ovale, Amblyomma tigrinum and Rhipicephalus sanguineus as well as Amblyomma spp. nymphs. One of the dogs displayed facial myoclonus, a symptom of canine distemper. Such disease is a serious viral and contagious disease of dogs and also of several wild animals. Overall tick species found on dogs clearly showed the transit of these hosts between the natural areas of the park and anthropic areas, urban or rural. Such situation illustrates the potential of dogs to transmit... |
