1. Factors influencing seed germination in Cerrado grasses
Few studies address the ecology of herbs of Cerrado grasslands, which are ecosystems where the long dry season, high temperatures, insolation, fire and invasive grasses greatly influencing germination and the establishment of plants. We assessed germination of 13 species of Poaceae from Cerrado grasslands under nursery conditions or in germination chambers,

2. An efficient system for in vitro propagation of Bouchea fluminensis (Vell.) Mold. (Verbenaceae)
This study aimed to establish and propagate in vitro plants of Bouchea fluminensis, a medicinal species known in Brazil as gervão-falso ("false verbena"), evaluating the influences of different growth regulators on in vitro multiplication and rooting stages, as well as examining ex vitro acclimatization of rooted plants. Explants were established on Murashi

3. Efeitos da arbórea introduzida Hovenia dulcis Thunb.(Rhamnaceae)sobre o componente árbóreo-arbustivo regenerante da floresta Atlântica no Sul do Brasil
Biological invasions by Hovenia dulcis Thunb., a tree from Asia, have been reported for Africa and South America. The present work aimed to evaluate the effects of the establishment of this exotic species on abundance, richness, species composition, growth, successional categories and beta diversity of natural regeneration in the Atlantic Rain Forest. Thus,

4. MAPEAMENTO DE ÁREAS ÚMIDAS E BANHADOS NA MICROBACIA DO RIO AMANDAÚ, REGIÃO NOROESTE DO RIO GRANDE DO SUL / MAPPING OF MOISTURE SOIL AND WETLANDS IN THE WATERSHED OF THE AMANDAU RIVER, NORTHWEST REGION OF RIO GRANDE DO SUL
The wetlands are one of the worlds most productive places, with high rates of biological diversity and also highly impacted. In this context, this project was aimed at mapping the Wetlands Ecosystems present in the soil moisture in the watershed of the Amandau River (Watershed U30), using orbital images and clinographic terrain maps. This research was struct

5. Development of the mosaic of dominant arboreal ants and its importance to the biological control of insects associated with cocoa (Theobroma cacao L.) / Desenvolvimento do mosaico de formigas arborícolas dominantes e sua importância no controle biológico natural dos insetos associados ao cacaueiro (Theobroma cacao L.)
Agroforests contribute to the survival of many native species. The cocoa plantations inserted in the Atlantic Forest biome in Southeast Bahia contribute to the conservation of a large amount of organisms, including ants. The evaluation of the ontogenetic succession of ants can help understanding the mosaic dynamics of the arboreal ants. Since this mosaic can

6. Etnoecologia e controle biológico conservativo em cafeeiros sob sistemas agroflorestais / Ethnoecology and conservation biological control in coffee cultures under agroforestry system
Esse estudo visou conciliar o conhecimento científico e popular para avaliar a possibilidade da utilização do ingá na composição de agroecossistemas cafeeiros, como uma estratégia de controle biológico conservativo. Os objetivos do primeiro capítulo foram: registrar como um grupo de agricultores familiares do município de Araponga, Zona da Mata Min

7. Hábito alimentar da rã invasora Lithobates catesbeianus (Shaw, 1802) e sua relação com anuros nativos na Zona da Mata de Minas Gerais, Brasil / Feeding habits of the invasive frog Lithobates catesbeianus (Shaw, 1802) and its relationship with native anurans in the Zona da Mata of Minas Gerais state, Brazil
The American Bullfrog (Lithobates catesbeianus) was introduced into several countries for commercial breeding, settling invasive populations during this process. In Brazil the beginning of its farming occurred on the 1930 s, and currently invasive populations can be found in the South, Southeast and Central-West regions. It has a generalist feeding habit, an

8. Mitochondrial control region haplotypes of the South American sea lion Otaria flavescens (Shaw, 1800)
The South American sea lion, Otaria flavescens, is widely distributed along the Pacific and Atlantic coasts of South America. However, along the Brazilian coast, there are only two nonbreeding sites for the species (Refúgio de Vida Silvestre da Ilha dos Lobos and Refúgio de Vida Silvestre do Molhe Leste da Barra do Rio Grande), both in Southern Brazil.

10. Biological control of Aphis gossypii Glover (Hemiptera: Aphididae) in protected crop of cucumber using Marigold (Tagetes erecta L.) / Controle BiolÃgico do pulgÃo Aphis gossypii Glover (Hemiptera: Aphidae) em cultivo protegido de pepino com cravo-de-defunto (Tageres erecta L.)
Protected crop is a used practice in Brazil and abroad. Some characteristics like stable climate, high temperature and availability of food, favor the occurrence of pests on these systems, among them the Aphis gossypii. These insects are usually controlled chemically, which when applied in closed systems have little dispersion, thereby increasing its concent

11. Bases ecológicas para o manejo de Bemisia tabaci (Genn.) biótipo B (Hemiptera: Aleyrodidae) em sistemas orgânicos de produção de tomate
The whitefly Bemisia tabaci biotype B stands out, among the diverse community of pest herbivores that colonize the tomato crop, due to the direct damages and transmission of several pathogenic viruses (Geminiviridae) causing productivity losses. The spraying of insecticides for its control selects resistant populations and promotes the dispersion of adults t

12. Development of a Multimetric Index of Ecological Integrity for streams in the urban area of Campo Grande (Mato Grosso do Sul), based on benthic macroinvertebrates / Desenvolvimento de um Índice Multimétrico de Integridade Ecológica para córregos na área urbana de Campo Grande (Mato Grosso do Sul), baseado em macroinvertebrados bentônicos
Water pollution is a growing problem, especially in the water courses that flow through urban centres, receiving residential, commercial and even industrial effluents. The small amount of control that exists is often done by means of physical, chemical and bacteriological analyses. The lack of a biological alternative may be due to the paucity of research in
