13. ASSOCIATIONS BETWEEN DENGUE AND SOCIO-ENVIRONMENTAL VARIABLES IN CAPITALS OF THE BRAZILIAN NORTHEAST BY CLUSTER ANALYSIS
Resumo Este artigo busca identificar, nas capitais do Nordeste brasileiro, o nível de similaridade entre dengue e variáveis climáticas, sociodemográficas e de saneamento, entre 2001-2012, através da análise de agrupamentos, uma técnica explanatória usada sobre dados multivariados para verificar o inter-relacionamento entre grupos formados pelas dist�

14. Breeding biology of Tyrannus melancholicus (Aves: Tyrannidae) in a restinga reserve of southeastern Brazil
ABSTRACT Existing knowledge of the breeding success and life history characteristics of most Neotropical bird species is scarce. Here, we help fill this gap by analyzing aspects of the breeding biology of the Tropical Kingbird Tyrannus melancholicus (Vieillot, 1819), which is a good model for this kind of study as it is a common species occurring in various

15. Urban malaria transmission in a non-endemic area in the Andean region of Colombia
BACKGROUND Rapid urbanisation in difficult socio-economic conditions such as inadequate housing infrastructure, lack of public services, improper sanitation, and poor water drainage systems in vegetation-rich areas lead to ecological conditions that are conducive to the breeding of mosquitoes and transmission of malaria, in semi-urban and urban settings. O

16. Detection of differentially methylated regions of irradiated fig tree selections
ABSTRACT Fig tree (Ficus carica L.) breeding programs using conventional methods, such as directed crosses, to obtain new cultivars, are unworkable in many countries, including Brazil. Consequently, genetic breeding through mutagenesis has emerged as an important line of research that can improve this crop, and be a significant source of information about th

17. Software Selegen-REML/BLUP: a useful tool for plant breeding
Abstract The software Selegen-REML/BLUP uses mixed models, and was developed to optimize the routine of plant breeding programs. It addresses the following plants categories: allogamous, automagous, of mixed mating system, and of clonal propagation. It considers several experimental designs, mating designs, genotype x environment interaction, experiments rep

18. New opportunities for developing tomato varieties with enhanced carotenoid content
ABSTRACT The development of varieties with a high content of antioxidant compounds, such as carotenoids, has become a major focus in the marketing of tomato. Several mutants have been used in the development of high pigment varieties, but the significant influence of the environment on carotenoid content and the presence of negative side effects in vegetativ

19. Identification of nurseries areas of juvenile Prochilodus lineatus (Valenciennes, 1836) (Characiformes: Prochilodontidae) by scale and otolith morphometry and microchemistry
ABSTRACT The streaked prochilod Prochilodus lineatus (Valenciennes) is a commercially freshwater species from South America, distributed in the Plata basin. In the present work the morphometry (circularity, rectangularity, form factor, OL/OW and ellipticity indices) and chemistry (Sr:Ca, Ba:Ca, Zn:Ca) of lapilli otolith, and geometric morphometry of scales o

20. Changes in infestation sites of female Aedes aegypti in Northeast Brazil
Abstract: INTRODUCTION: We report the behavioral changes in use of oviposition sites in Aedes aegypti in Fortaleza, Brazil. METHODS: We evaluated the relationship between different types of breeding sites and changes in use from 2001 to 2012. RESULTS: More than 40% of the infested breeding sites were used to store water. We observed a three-fold reducti

21. Diversity of yellow fever mosquito vectors in the Atlantic Forest of Rio de Janeiro, Brazil
Abstract: INTRODUCTION: Environmental modifications caused by human activities have led to changes in mosquito vector populations, and sylvatic species have adapted to breeding in urban areas. METHODS: Mosquitoes were collected using ovitraps in three sampling sites in the Atlantic Forest in the State of Rio de Janeiro, Brazil. RESULTS: We collected 2,162

22. Spatial and temporal country-wide survey of temephos resistance in Brazilian populations of Aedes aegypti
The organophosphate temephos has been the main insecticide used against larvae of the dengue and yellow fever mosquito (Aedes aegypti) in Brazil since the mid-1980s. Reports of resistance date back to 1995; however, no systematic reports of widespread temephos resistance have occurred to date. As resistance investigation is paramount for strategic decision-m

23. Cytological aspects of incompatible and compatible interactions between rice, wheat and the blast pathogen Pyricularia oryzae
ABSTRACT Blast, caused by the fungus Pyricularia oryzae, is an important disease affecting rice and wheat yield worldwide. This study investigated the cytological aspects of incompatible (non-host resistance) and compatible (host resistance) rice- (R_Po) and wheat- (W_Po) Pyricularia oryzae isolate interactions. Inoculations of rice and wheat with the R_Po a

24. Malaria in gold-mining areas in Colombia
Gold-mining may play an important role in the maintenance of malaria worldwide. Gold-mining, mostly illegal, has significantly expanded in Colombia during the last decade in areas with limited health care and disease prevention. We report a descriptive study that was carried out to determine the malaria prevalence in gold-mining areas of Colombia, using data
