1. Maintenance of wetland plant communities: the role of the seed bank in regeneration of native plants
ABSTRACT Exotic grasses have been introduced into wetlands and can compete with native plants due to their high tolerance of flood and dry periods. Flooding can facilitate seed dispersal of exotic species and reduce the diversity of native species. We compared two grasslands to assess whether seed banks can maintain the diversity of native plants in wetlands

2. Incorporação de biomassa de fabáceas ao substrato de plantio para controle da podridão-de-escleródio (Sclerotium rolfsii) em cubiu (Solanum sessiliflorum)
RESUMO O cultivo do cubiu (Solanum sessiliflorum Dunal), no Amazonas, é limitado pela alta incidência da doença podridão-de-escleródio (Sclerotium rolfsii Sacc.) e a incorporação de material vegetal ao substrato de cultivo altera a microflora presente. O trabalho objetivou avaliar o potencial de controle da podridão-de-escleródio em cubiu por meio d

3. PLANT RICHNESS AND LIFE FORM DIVERSITY ALONG VEGETATION AND FOREST USE GRADIENTS IN NORTHWESTERN PATAGONIA OF ARGENTINA
ABSTRACT The imbalace between the increase in the demand and the decrease in the supply of products from natural forests, partly explains the on-going development of exotic tree plantations. In northwestern Patagonia of Argentina, Pinus ponderosa (Pinaceae) afforestation plays a key role in ameliorate degraded soils, but may also reduce biodiversity. The eco

4. Native and ornamental exotic resources in pollen loads and garbage pellets of four stingless bees (Apidae, Meliponini) in an urban environment with riparian native forest
Abstract: An entomopalynological study to assess pollen use by wild bees was performed in an urban environment with riparian native forest in the Chaco region of Argentina. A combined method for sampling pollen loads and garbage pellets at nest entrances in four stingless bees with different entrance size and forager traffic was here successfully used. Samp

5. 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

6. Exóticas, exóticas, exóticas: reflexões sobre a monótona arborização de uma cidade brasileira
Resumo A despeito da grande diversidade de espécies nativas do país, é comum que a arborização das cidades brasileiras seja constituída majoritariamente por espécies exóticas, algumas das quais invasoras. Isso tem resultado na pouca valorização que as espécies nativas têm recebido no paisagismo do país. Neste trabalho buscou-se caracterizar a ar

7. As plantas comestíveis no Brasil dos séculos XVI e XVII segundo relatos de época
Resumo Este trabalho objetivou estudar a flora comestível do Brasil nos séculos XVI e XVII a partir dos textos de 18 autores que estiveram no país durante este período. As plantas citadas foram identificadas por similaridade a partir das descrições textuais e imagens disponíveis nas obras estudadas, considerando a origem, área de ocorrência e nome p

8. Avaliação qualiquantitativa da arborização da sede dos municípios de Beberibe e Cascavel, Ceará, Brasil
Resumo A presente pesquisa objetivou realizar um inventário fitossociológico qualiquantitativo, do tipo censo, das ruas e avenidas da zona urbana dos municípios de Beberibe e Cascavel, Ceará. A análise foi realizada no período de ago/2014 à jul/2016. Foram inventariados 636 indivíduos, sendo 512 de Cascavel e 124 de Beberibe, distribuídos em 18 esp�

9. Compositional Similarity of Urban Green Areas in Southeastern Brazil
ABSTRACT Urban afforestation greatly contributes to the ex situ conservation of native species in urban centers of Brazil. In this way, the aim of the present work was to analyze the similarity of the arboreal-shrub flora among urban afforestation in southeastern Brazil. For this analysis, a binary matrix with data of 283 species present in 20 municipalities

10. 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

11. Physiological response of Cucurbita pepo var. pepo mycorrhized by Sonoran desert native arbuscular fungi to drought and salinity stresses
ABSTRACT Plants response to symbiosis with arbuscular mycorrhizal fungi (AMF) under water stress is important to agriculture. Under abiotic stress conditions native fungi are more effective than exotics in improving plant growth and water status. Mycorrhization efficiency is related to soil fungi development and energy cost-benefit ratio. In this study, we a

12. Insect Galls of the Parque Nacional do Itatiaia (Southeast Region, Brazil)
ABSTRACT The Parque Nacional do Itatiaia (PNI) (Brazilian Southeast Region) was surveyed monthly for insect galls from February/2014 to December/ 2015. A total of 432 gall morphotypes were found. This number places the PNI as the richest Atlantic forest area in number of gall morphotypes. The galls were found on 47 plant families. Among them, Asteraceae were
