1. The invasive tropical tanner grass decreases diversity of the native aquatic macrophyte community at two scales in a subtropical tidal river
ABSTRACT The tropical tanner grass, Urochloa arrecta, is one of the worst aquatic plant invaders in Brazilian freshwater ecosystems. This study aimed to compare beds of macrophytes dominated and without U. arrecta in the Guaraguaçu River, a subtropical tidal river in South Brazil, to analyze effects that this invasive grass has on the biodiversity of native

2. Seed germination and dormancy break in Eragrostis polytricha, a native Brazilian grass species with potential for recovery of degraded lands
ABSTRACT Ferruginous Rocky Outcrops have high levels of species richness and endemism, but have been threatened by several anthropic actions, especially mining. Eragrostis polytricha, a common grass species in the vegetation of these outcrops, has shown promising features for use in the recovery of mining areas. However, in order to fully understand the spec

3. Urochloa decumbens Has Higher Mycorrhizal Colonization in Degraded than in Pristine Areas in the Brazilian Cerrado
ABSTRACT Brazil has extensive degraded areas, where vegetation fails to establish due to harsh soil conditions. However, some invasive species such as Urochloa decumbens are successful pioneers in such areas, but the reasons deserve investigation. Mycorrhizal fungi are abundant in Cerrado soils, and their association with plants are beneficial for their esta

4. EXOTIC ARBUSCULAR MYCORRHIZAL FUNGI AND NATIVE DARK SEPTATE ENDOPHYTES ON THE INITIAL GROWTH OF Paspalum millegrana GRASS
RESUMO Os fungos micorrízicos arbusculares (FMA) e os endofíticos “dark septate” (DSE) podem promover o incremento da biomassa vegetal, a depender das condições edafoclimáticas e da interação com a planta hospedeira. O objetivo deste trabalho foi avaliar a interação de fungos micorrízicos arbusculares exóticos e fungos endofíticos DSE nativos

5. FORAGE PRODUCTION AND PRESERVATION OF SPECIES BY ENRICHING CAATINGA WITH GRASSES AND THINNING AREAS INTO STRIPS
RESUMO O objetivo deste estudo foi avaliar o raleamento em faixas e o enriquecimento com gramíneas exóticas em uma área de Caatinga, de modo que fosse possível manter e ou aumentar a biodiversidade de espécies vegetais nativas, e intensificar a produção de biomassa de forragem. Dois estudos foram conduzidos em uma área de Caatinga raleada em faixas e

6. Impact of agro-farming activities on microbial diversity of acidic red soils in a Camellia Oleifera Forest
ABSTRACT The production of Camellia oleifera (oil tea), typically planted in acidic red soils in southern China, is limited by low soil fertility. Agro-farming is one way to promote soil fertility by increasing organic matter and microbial communities. To understand the impact of agro-farming activity on soil fertility, three types of agro-farming, namely, r

7. Uso de mantas geotêxteis na revegetação de um fragmento de mata de galeria no Jardim Botânico de Brasília - DF: sobrevivência e desenvolvimento de mudas
Resumo Atividades antrópicas têm causado danos ao Cerrado, segundo maior bioma do Brasil. Entre as formações vegetais mais ameaçadas do bioma Cerrado, destaca-se a Mata de Galeria. Programas de recuperação tentam restaurar essa fitofisionomia, mas ervas invasoras dificultam o estabelecimento e o desenvolvimento de espécies nativas lenhosas. Nesse cen

8. NATIVE MICROBIOTA AND ARBUSCULAR MYCORRHIZAL FUNGI ON GROWTH OF Paspalum millegrana SCHRAD
RESUMO Paspalum millegrana é uma poácea nativa das Américas, cuja interação com fungos simbiontes nativos ainda não pode ser encontrada na literatura. O objetivo deste trabalho foi avaliar a interação entre microrganismos nativos e fungos micorrízicos arbusculares no crescimento de P. millegrana Schrad. O delineamento experimental utilizado foi inte

9. Survey of dental diseases in Crioulo breed horses reared in an extensive farming system
RESUMO O presente estudo teve por objetivo identificar e quantificar as afecções odontológicas de equinos da raça Crioula criados exclusivamente em regime extensivo. No total, foram avaliados 254 cavalos Crioulos, criados em pastagens nativas com predominância de Eragrostis plana (capim-annoni). Os animais foram divididos em três grupos, de acordo com

10. Intraspecific tetraploid hybrids of Paspalum notatum: agronomic evaluation of segregating progeny
ABSTRACT: For many decades, animal production in southern Brazil has been based on native forage grasses. Paspalum notatum Flügge (bahiagrass) is one of the most frequently used native grass in southern Brazil. The native germplasm of P. notatum is tetraploid and displays apomictic reproduction; hence, chromosome doubling of sexual diploid accessions is req

11. Management techniques for the control of Melinis minutiflora P. Beauv. (molasses grass): ten years of research on an invasive grass species in the Brazilian Cerrado
ABSTRACT The invasion of exotic species is considered to be a major threat to the preservation of biodiversity. In the Parque Nacional de Brasília (National Park of Brasília), the invasive Melinis minutiflora (molasses grass) occupies more than 10 % of the area of the park. The present, long-term, study compared two treatments of exposure to molasses grass

12. Land Use and Environmental Zoning of Mixed Ombrophilous Forests for Sustainable Use (Irati National Forest, Brazil Southern Region)
ABSTRACT An environmental zoning proposal due to the demand to develop strategies to ensure biodiversity scenarios for the remaining mixed ombrophilous forests was carried out for the Irati National Forest, a legally protected area for sustainable use located in southern Brazil. To identify land use and cover, Ikonos PSM images dated from December 2004, base
