1. ENDOPHYTIC FUNGI COMMUNITY IN Eremanthus erythropappus TREE FROM ANTHROPOGENIC AND NATURAL AREAS OF MINAS GERAIS
ABSTRACT It is know that many plants live in symbiosis with microorganisms that can be found on their interior, the endophytes. Environment and tissue type are modulating factors of this community, in which most of these microorganisms produce important antimicrobial molecules and they may be powerful biocontrol agents in agriculture. Thus, the aim of this s

2. Risk of genetic vulnerability and aspects of the reproductive biology of Psychotria ipecacuanha (Rubiaceae), a threatened medicinal plant species of Brazilian forests
ABSTRACT Psychotria ipecacuanha, commonly known as Ipeca, is a medicinal plant of pharmacological and economic value. The species is distylous; it has populations with two floral morphs, one with long and one with short styles. Apart from the presence of two floral morphs in a balanced ratio (1:1), reciprocal herkogamy of the reproductive organs between alte

3. Relationship of Neotropical otter vestiges with environmental and anthropogenic factors
RESUMO A lontra neotropical, Lontra longicaudis é um mustelídeo semiaquático que usa seu habitat de diferentes formas. Para entender a influência relativa de fatores antrópicos e ambientais sobre a distribuição de lontras neotropicais, nós conduzimos monitoramentos sistemáticos de vestígios de lontras na região do médio Rio Guamá, Pará, Amazôn

4. Metrics of benthic communities and habitat quality associated to different types of land use
RESUMO Os ecossistemas aquáticos estão sob fortes modificações antrópicas. Assim, comunidades biológicas dependentes desses ambientes também são alteradas. O objetivo deste estudo foi investigar os efeitos do desenvolvimento urbano em um ecossistema impactado. Foram selecionadas 15 seções de amostragem ao longo do Ribeirão Vermelho e em cada uma f

5. Anuran diversity in urban and rural zones of the Itacoatiara municipality, central Amazonia, Brazil
RESUMO Poucos estudos avaliaram a diversidade de anuros em fragmentos florestais urbanos ou em áreas com diferentes graus de impacto antrópico na Amazônia. Neste estudo foi determinada a composição e abundância de anuros em áreas urbanas e rurais no município de Itacoatiara, na Amazônia central, Brasil. Anuros foram amostrados entre janeiro de 2012

6. Anuran species in a remnant of the Atlantic rainforest in an urban area
Abstract Forest fragments in urban areas have many habitat resources that frogs use for refuge, reproduction and growth. Knowledge of an anuran assembly is the first step towards understanding the importance of these forest fragments in areas highly threatened by anthropogenic actions. We sampled anurans during the day and night from November 2012 to August

7. Rapid Assessment of Habitat Diversity Along the Araras Stream, Brazil
ABSTRACT Agriculture, urbanization, and industrialization are some of the anthropogenic activities that constantly generate negative impacts on natural environments. Part of this degradation directly affects aquatic systems. This study aimed to evaluate the visual characteristics of the Araras Stream, located in the municipality of Araras, São Paulo state,

8. Genetic diversity of Morato's Digger Toad, Proceratophrys moratoi: spatial structure, gene flow, effective size and the need for differential management strategies of populations
Abstract The Morato's Digger Toad, Proceratophrys moratoi, is a critically endangered toad species with a marked population decline in southern Brazilian Cerrado. Despite this, new populations are being discovered, primarily in the northern part of the distribution range, which raises a number of questions with regard to the conservation status of the specie

9. Invading the natural marine substrates: a case study with invertebrates in South Brazil
ABSTRACT The number of biological invasions has grown dramatically in recent decades, as well as the world's human population and coastal development. Anthropogenic habitats, such as pier pilings and break waters, have been constantly added to marine environment, usually concentrated in estuarine areas. These habitats are focal points for marine invasions, b

10. The structural heterogeneity of an urbanised mangrove forest area in southeastern Brazil: Influence of environmental factors and anthropogenic stressors
Resumo O objetivo deste estudo foi avaliar as características das florestas de um manguezal urbanizado, usando estrutura da vegetação e fatores abióticos para distinguir a heterogeneidade/qualidade do habitat. Foram selecionadas 16 áreas na Baía de Vitória, nas florestas de franja e de bacia. Os dados avaliados foram altura, DAP, área basal, densidad

11. Structure and floristic diversity of remnant semideciduous forest under varying levels of disturbance
The perturbation of Neotropical forests generates large disturbances in biological communities. The species that suffer least from the resulting habitat fragmentation are the pioneers, because they possess greater ability to inhabit disturbed environments. Therefore, it is expected that species diversity will be greater in areas subjected to intermediate dis

12. Threats to and viability of the giant anteater, Myrmecophaga tridactyla (Pilosa: Myrmecophagidae), in a protected Cerrado remnant encroached by urban expansion in central Brazil
Urbanization poses a serious threat to wildlife populations inhabiting native vegetation remnants surrounded by the expanding urban and suburban sprawl. The close contact with human activities causes not only direct impacts, such as habitat loss, but also indirect negative effects, such as population isolation, roadkills and anthropogenic fires.
