1. Spatial Clustering of Extreme Annual Precipitation in Uruguay
Resumo O objetivo principal deste trabalho é estudar a existência de padrões espaciais de precipitação máxima anual (através de observações diárias) no território do Uruguai e mostrar a aplicação de duas novas ferramentas estatísticas recentemente propostas. Na primeira etapa, serão estudadas as distribuições da precipitação máxima anual

2. CLIMATE ZONING FOR THE CULTIVATION OF AFRICAN MAHOGANY SPECIES IN BRAZIL
ABSTRACT African mahogany is the common name given to different species of the genus Khaya. They are tree species native to the African continent, which have a wood quality that allows their noble use in making fine furniture, and in the civil and naval industries. Currently, African mahogany cultivation has received notoriety in Brazil and given its climati

3. Geração de Curvas IDFs para Cenários Projetados na Cidade de Porto Alegre/RS
Resumo O aumento na frequência de eventos extremos associados às alterações climáticas podem modificar as curvas IDFs existentes. A metodologia para definição de curvas IDF considerando cenários futuros consistiu em calibrar o modelo estocástico para gerar séries sintéticas diárias de precipitação com base em dados observados do município de P

4. Time-space characterization of droughts in the São Francisco river catchment using the Standard Precipitation Index and continuous wavelet transform
RESUMO Este artigo enfatiza a caracterização espaço-temporal de secas na bacia do rio São Francisco, com base na análise de ondaletas de séries temporais do Índice Padronizado de Precipitação (SPI). Para melhorar a estimação do SPI, os procedimentos para análise regional por momentos-L foram empregados na delimitação de regiões estatisticament

5. Application of indices for water resource systems stress assessment
RESUMO O presente artigo teve como objetivo apresentar uma metodologia para avaliação do estresse hídrico de sistemas de recursos hídricos por meio de índices. Neste caso, aplicou-se a metodologia proposta ao Sistema Cantareira, um dos principais sistemas produtores de água da Região Metropolitana de São Paulo (RMSP). Foram utilizados para esta aval

6. Using climate change models to assess the probability of weather extremes events: a local scale study based on the generalized extreme value distribution
ABSTRACT Regional climate models (e.g. Eta) nested to global climate models (e.g. HadGEM2-ES and MIROC5) have been used to assess potential impacts of climate change at regional scales. This study used the generalized extreme value distribution (GEV) to evaluate the ability of two nested models (Eta-HadGEM2-ES and Eta-MIROC5) to assess the probability of dai

7. SPATIALIZATION OF THE ANNUAL MAXIMUM DAILY RAINFALL IN SOUTHEASTERN BRAZIL
ABSTRACT Extreme rainfall can lead to heavy damage and losses, such as landslides, floods and agricultural productivity as well as the loss of human and animal lives. To mitigate these losses, water resources management policies are needed, among other goals, to study and predict the frequency of such events in a given region to minimize their harmful effect

8. 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,

9. Effects of salinity on the physiology of the red macroalga, Acanthophora spicifera (Rhodophyta, Ceramiales)
ABSTRACT Salinity is an important abiotic factor since it is responsible for the local and/or regional distribution of algae. In coastal regions, salinity changes with prevailing winds, precipitation and tide, and particularly in extreme intertidal conditions. Acanthophora spicifera is a red seaweed that occurs in the supratidal region in which changes in ab

10. Inter- and intra-population variability in physical dormancy along a precipitation gradient
ABSTRACT Physical dormancy enables plants that occur in temporally stochastic and harsh environments to survive; thus, within the distribution area of a species, the percentage of seeds with physical dormancy is expected to increase towards more arid and unpredictable areas. There have been no previous studies evaluating both inter and intra-population varia

11. Purification and characterization of extracellular α-amylase from a thermophilic Anoxybacillus thermarum A4 strain
ABSTRACT α-Amylase from Anoxybacillus thermarum A4 was purified using ammonium sulphate precipitation and Sephadex G-100 gel filtration chromatography, with 29.8-fold purification and 74.6% yield. A4 amylase showed best performance for soluble potato starch hydrolysis at 70 °C and pH 5.5-10.5. A4 amylase was extremely stable at +4 °C, and the enzyme retai

12. Ocorrência de ventos fortes no estado do Paraná : gênese e impactos
The knowledge of climatic conditions is essential to socioeconomic activities, especially for agricultural and urban planning. Thus has the objective of this work to present a study of winds in the state of Paraná, which was established by calculating and analyzing daily, monthly and yearly mean wind speed, relative frequency, distribution of the accumulate
