1. Arbuscular mycorrhizal fungi and Urochloa brizantha: symbiosis and spore multiplication
RESUMO Fungos micorrízicos arbusculares (FMA) podem apresentar comportamentos distintos, quando associados à mesma espécie de planta hospedeira, sendo necessário compreender sua ecologia, visando a otimizar o seu manejo e manutenção em banco de germoplama. Objetivou-se avaliar diferentes FMA associados a Urochloa brizantha (A. Rich.) Stapf, analisando-

2. Perception and use of non-native and invasive flora from Sierras de Córdoba in central Argentina
ABSTRACT The perception, knowledge and use of non-native and invasive flora by social actors associated with protected areas in central Argentina were analyzed. Contemporary ethnoecology methods were followed. A total of 108 non-native species of botanical interest was documented. An organization of species is proposed according to their Relative Importance,

5. Institutional change and accountability: procedural ecology and defiance of the Brazilian case
Resumo Este artigo analisa o processo de mudança institucional nas instituições de accountability no Brasil, com foco em processos endógenos, exógenos e sistêmicos. Os estudiosos geralmente analisam a mudança institucional considerando fatores explicativos endógenos e exógenos para falar sobre a direção e os resultados das mudanças. Além desses

6. Biological control of fruit flies in Brazil
Resumo: As moscas-das-frutas são as principais pragas da fruticultura no Brasil. O seu manejo tem sido realizado predominantemente com uso de inseticidas aplicados por cobertura e/ou na forma de isca-tóxica. Atualmente, a tendência das estratégias de manejo está direcionada à adoção de métodos de controle que causem menor impacto ambiental em grande

7. Factors associated with the presence of triatomines in rural areas of south Argentine Chaco
Abstract INTRODUCTION: The domestic and peridomestic presence of Triatoma infestans depends on several factors, such as human behavior, vector behavior, ecology, and the environment. METHODS: This work was conducted in 139 domiciliary units, where triatomines were captured and risk factors in domiciles and peridomicilies were recorded. Household dwellers

8. A Bayesian analysis of the parasitic ecology in Jenynsia multidentata(Pisces: Anablepidae)
ABSTRACT Jenynsia multidentata Jenyns, 1842 (one-sided livebearers) are euryhaline viviparous fish of small size, used in the laboratory experiment, important as resource for biological control of mosquito’s larva and a key species to recover eutrophic lakes. Works have been published dealing with parasite biodiversity of this host, but little has been stu

9. Anopheles fauna of coastal Cayenne, French Guiana: modelling and mapping of species presence using remotely sensed land cover data
Little is known about the Anopheles species of the coastal areas of French Guiana, or their spatiotemporal distribution or environmental determinants. The present study aimed to (1) document the distribution of Anopheles fauna in the coastal area around Cayenne, and (2) investigate the use of remotely sensed land cover data as proxies of Anopheles presence.

10. 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,

11. Lutzomyia longipalpis urbanisation and control
Since the description of Lutzomyia longipalpis by Lutz and Neiva more than 100 years ago, much has been written in the scientific literature about this phlebotomine species. Soares and Turco (2003) and Lainson and Rangel (2005) have written extensive reviews focused on vector-host-parasite interactions and American visceral leishmaniasis ecology. However, du

12. A historical perspective on malaria control in Brazil
Malaria has always been an important public health problem in Brazil. The early history of Brazilian malaria and its control was powered by colonisation by Europeans and the forced relocation of Africans as slaves. Internal migration brought malaria to many regions in Brazil where, given suitableAnopheles mosquito vectors, it thrived. Almost from the start,
