| The Pantanal is an extensive sedimentary plain, with seasonal flooding and where extensive livestock farming is the main economic activity. Flood seasonality is a natural process in wetlands, it naturally fertilizes native pastures that occur in large areas in the Pantanal, being the basis of cattle feed. In regions that flood by overflowing rivers or those that flood directly because of rain, large areas of native pasture are submerged from time to time with critical depths and durations, and in extreme events, there may be a drastic reduction in the supply of food and even an increase of cattle mortality due to starvation or drowning. Over more than 200 years of coexisting with floods, management strategies such as the removal of cattle from low,... |

| Para la generación de mapas digitales de inundación es necesario tener presente los conceptos de cartografía y modelación numérica de tsunamis, usando como nexo a los Sistemas de Información Geográfica (SIG). La utilización SIG no es nuevo en el modelamiento de tsunamis, sin embargo el uso general de esta técnica en países como el Ecuador es reciente. Por esta razón, como contribución a la determinación del riesgo por tsunamis, se presenta esta metodología para elaborar cartas digitales de inundación basada en la unión de las técnicas SIG y el Proyecto TIME (Intercambio de mapas de inundación por Tsunamis). Los aspectos cartográficos considerados en la preparación de estos mapas son: la línea de costa de alta resolución y el uso de un mismo sistema de... |

| The southern part of Mozambique suffered, at the beginning of the present year, the worst floods in the last 50 years, which caused several fatalities and high material losses. The objective of this study was to investigate the influence of this phenomenon on the coral communities of the Xai-Xai lagoon reef. Benthic category percentage cover was assessed in January 2000 (before the floods) and September 2000 (after the floods) using the line intercept transect (LIT). A decrease of hard coral percentage cover was observed, in the order of 58.5 %. The soft coral community was also affected, with a high decrease of percentage cover, about 90.4%. Other benthic category that showed an elevated decrease was coralline algae (85.1%). All other categories increased... |

| The Brazilian Pantanal comprises a mosaic of forest and field environments harbouring a rich community of large and midsized mammals that are adapted to the annual hydrological cycle. Here we evaluated richness and composition of large and midsized mammals inhabiting forested and open habitats affected by yearly floods in the Pantanal in Cáceres from October 2009 to September 2010. We compared these communities in marshes, dry forests and riparian forests based on 640 camera-traps.nights, sights, tracks, faecal samples and interviews. We also compared results in a private land (Descalvados Farm) and in a protected area (Taiamã Ecological Station). In total, we sampled 26 large and midsized mammals, including five threatened and two near threatened species.... |

| The environment is impacted by natural and anthropogenic disturbances that occur at different spatial and temporal scales, and that lead to major changes and even disequilibria when exceeding the resiliency capacities of the ecosystem. With an annual mean flow of 1700 m(3) s(-1), the Rhone River is the largest of the western Mediterranean basin. Its annual solid discharges vary between 2 and 20 Mt, with flood events responsible for more than 70% of these amounts. In the marine coastal area, close to the mouth, both flocculation and aggregation lead to the formation of fine-grained deposits, i.e. the prodelta. This area is characterized by sediment accumulation rates up to 20-50 cm yr(-1) and high accumulations of particle reactive contaminants such as... |

| Offshore archives retrieved from marine/lacustrine environments receiving sediment from large river systems are valuable Quaternary continental records. In the present study, we reconstruct the Danube River activity at the end of the last glacial period based on sedimentological, mineralogical and geochemical analyses performed on long-piston cores from the north-west Black Sea margin. Our data suggest that the Danube River produced hyperpycnal floods throughout the ca. 33-17 ka period. Four main periods of enhanced Danube flood frequency, each of 1.5-3 kyr duration, are recorded at ca. 32.5 30.5 ka (equivalent to the first part of Heinrich Stadial HS 3), at ca. 29-27.5 ka (equivalent to Greenland Stadial 4), at ca. 25.3-23.8 ka (equivalent to HS 2) and at... |

| O Pantanal é conhecido pela sua riqueza ictiofaunística e constitui região de pesca visitada por muitos pescadores esportivos. Mas o que faz com que esse tipo de ambiente inundável seja tão rico em peixes? Esse artigo se propõe a responder a essa questão, mostrando que o pulso de inundação, o encher e secar a cada ano, típico de ambientes inundáveis, é o processo ecológico que regula sua fauna e flora, particularmente os peixes. Para tanto foi escolhido um braço abandonado do Rio Paraguai, denominado localmente como Baía do Tuiuiú, onde se estudou o ambiente, em termos de vegetação circundante, as características limnológicas de suas águas e suas relações com os peixes ocorrentes em termos de composição, riqueza, diversidade e suas estratégias de vida. |

| Segundo o Painel Intergovernamental sobre Mudança do Clima, os eventos extremos que vem sendo observados nas últimas décadas e aqueles previstos para o futuro, são uma consequência das mudanças climáticas em função das atividades humanas. Independente da causa, mudanças climáticas ou variabilidade climática natural, eventos extremos ocorrem eventualmente e causam preocupação na sociedade, devido ao risco de perdas de vidas humanas, de propriedades e econômicas. Medidas de adaptação às mudanças climáticas são fundamentais para minimizar os riscos. |
