26. Variabilidade dos casos de malária e sua relação com a precipitação e nível d’água dos rios no Estado do Amazonas, Brasil
O entendimento das relações entre as variáveis de precipitação e nível d’água dos rios com os casos de malária podem fornecer indícios importantes da modulação da doença no contexto da variabilidade climática local. No intuito de demonstrar como essas relações variam no mesmo espaço endêmico, realizou-se a análise de coerência e fase de

27. Edaphic-Climatic Zoning of Eucalyptus Species in the Rio de Janeiro State, Brazil
ABSTRACT The aim of this study was to perform the edaphic-climatic zoning of six eucalyptus species (E. camaldulensis, C. citriodora, E. cloeziana , E. grandis, E. saligna, and E. urophylla) in the state of Rio de Janeiro (RJ). The edaphic-climatic zoning was determined by overlayer of thermal and water (water deficit [DEF] and rainfall), type of soils (ped

28. Ecological capability evaluation for afforestation and forest expansion using Geographic Information System (GIS) in management area of Caspian Sea
Abstract Ecological capability evaluation is referred to as evaluation of potential capability of land and determination of its natural land use. In this paper, ecological capability of Lille Basin in Lahijan was evaluated for afforestation and forest expansion using Geographical Information Systems (GIS). For this purpose, information layers (slope, elevati

29. Corn grain yield and 15N-fertilizer recovery as a function of urea sidedress timing
Abstract Best fertilizer management practices such as adopting the right N sidedress timing can reduce N losses by volatilization, thus, raising N-fertilizer recovery and grain yield. To evaluate ammonia (N-NH3 ) losses, N-fertilizer recovery and grain yield as a function of urea sidedress timing in corn, a field study was conducted during the 2011-2012 and

30. ANALYSIS OF THE PHENOLOGY DYNAMICS OF BRAZILIAN CAATINGA SPECIES WITH NDVI TIME SERIES
ABSTRACT In Brazil there are six well-defined biomes and the Caatinga represents 9.92% of the total area. This biome is exclusively Brazilian and very rich in biodiversity. Because it has low resistance to human interference is necessary to know the important factors in monitoring the biome. Vegetation coverage and climate are two of these factors, as they i

31. Ecological drivers of plant genetic diversity at the southern edge of geographical distributions: Forestal vines in a temperate region
Abstract The Tropical Niche Conservatism hypothesis is one of the most relevant theories to explain why tropical diversity is high, although the mechanisms underlying this hypothesis require further clarification. A possible research avenue to address the underlying mechanisms includes determining population-level processes associated with such a hypothesis,

32. Factors that influence in Jatropha curcas L. latex production
ABSTRACT Latex from Jatropha curcas L. exhibits biotechnological potential for the development of biodiesel and drugs. Little is known about the collection methods and latex productivity of this species. In order to garner information on the use of J. curcas latex, factors that influence production by this species were assessed. As a result, no significant d

33. Performance of two honey bee subspecies during harsh weather and Acacia gerrardii nectar-rich flow
ABSTRACT Both climatic factors and bee forage characteristics affect the population size and productivity of honey bee colonies. To our knowledge, no scientific investigation has as yet considered the potential effect of nectar-rich bee forage exposed to drastic subtropical weather conditions on the performance of honey bee colonies. This study investigated

34. Relationship between climatic factors and air quality with tuberculosis in the Federal District, Brazil, 2003-2012
Abstract Introduction: Despite the high rate of tuberculosis indicators in Brazil, the Federal District shows a low prevalence of the disease. Objective: To analyze the relationship between climatic factors and air quality with tuberculosis in the Brazilian Federal District. Methodology: This was an ecological and descriptive study comparing 3927 new case

35. Length/weight relationship and condition factor of Macrobrachium jelskii (Miers, 1877) and M. brasiliense (Heller, 1862) (Decapoda, Palaemonidae) in two locations in the state of São Paulo
Abstract This study describes the weight vs. carapace length relationship and provides the total and monthly condition factor values for populations of Macrobrachium jelskii (Miers, 1977) and M. brasiliense (Heller, 1868) occurring in southeastern Brazil. The biological characteristics were compared and related to the climatic environmental factors between t

36. Global patterns of aboveground carbon stock and sequestration in mangroves
ABSTRACT In order to contribute to understand the factors that control the provisioning of the ecosystem service of carbon storage by mangroves, data on carbon stock and sequestration in the aboveground biomass (AGB) from 73 articles were averaged and tested for the dependence on latitude, climatic parameters, physiographic types and age. Global means of car
