3. New Contours of the Native Vegetation Protection Law of 2012
ABSTRACT The conservation of natural resources within rural properties is a constitutional obligation. Among the social function criteria required for the exploitation of rural properties, besides the rational use and respect of working conditions, there is a need to ensure environmental protection. The current guidelines regarding the exploration and the en

4. Plant-canopy Effects on Natural Regeneration in Sites Under Restoration: Do Tree Species Matter?
ABSTRACT How does species choice influence ecological restoration outcomes? In order to answer this question, the goal of this study was to assess the community structure and species richness of natural regeneration beneath the canopy of four native species from the Atlantic Forest (Guarea guidonia (L.) Sleumer; Inga edulis Mart; Nectandra membranacea (SW) G

6. Spatial-temporal variation in litterfall in seasonally dry tropical forests in Northeastern Brazil
Resumo A produção de serapilheira é essencial para a ciclagem de nutrientes em ecossistemas terrestres. De Novembro de 2009 a Outubro de 2011, foi analisada a produção de serapilheira em duas áreas de Caatinga, um tipo de Floresta Tropical sazonalmente Seca localizada no Cariri Paraibano, na região do semiárido da Paraíba, Nordeste do Brasil. Uma da

7. Impacto da remoção de serapilheira sobre a comunidade de artrópodes edáficos em plantios abandonados de Corymbia citriodora
Resumo Experimentos de manipulação podem contribuir para a compreensão do papel ecológico da serapilheira em ecossistemas florestais. No entanto, há poucos estudos desta natureza. Os efeitos da remoção da camada de serapilheira (RS) foram avaliados sobre a comunidade de artrópodes do solo em dois plantios abandonados de Corymbia citriodora, em difere

8. Ecological aspects of natural populations of Hyalella pampeana (Crustacea, Amphipoda, Hyalellidae) from the Natural Reserve Island of Martín García (Río de La Plata, Argentina)
Abstract: Freshwater amphipods of the genus Hyalella have a great importance in aquatic ecosystems due to their role in matter and energy cycling and its utilization as bioindicators of environmental health. The aim of this work was to analyze relevant population parameters of Hyalellapampeana, such as population density and structure, individual body size,

9. Management priorities for exotic plants in an urban Atlantic Forest reserve
ABSTRACT Biological diversity is directly affected by alien species, even though the diagnosed impacts vary with scale. Early identification of the invasion of natural patches is essential for effective conservation actions. We aimed to determine the exotic plant species present inside Fontes do Ipiranga State Park (PEFI), an urban protected area located in

10. Peptidomic investigation of Neoponera villosa venom by high-resolution mass spectrometry: seasonal and nesting habitat variations
Abstract Background: Advancements in proteomics, including the technological improvement in instrumentation, have turned mass spectrometry into an indispensable tool in the study of venoms and toxins. In addition, the advance of nanoscale liquid chromatography coupled to nanoelectrospray mass spectrometry allows, due to its high sensitivity, the study of ve

12. Eficiencia de las unidades de conservación definidas en la Reserva Natural Iberá (Argentina) en la protección de la diversidad de reptiles
ABSTRACT Owing to accelerated biodiversity loss caused by human activities, the protected areas (PAs) are the main response to mitigate this crisis. The Iberá Natural Reserve (INR) includes 13000 km2 of private and state lands, which contain wetland and upland areas with high biodiversity, endemism and significant populations of threatened species. In order
