| How temperate forests will respond to climate change is uncertain; projections range from severe decline to increased growth. We conducted field tests of sessile oak (Quercus petraea), a widespread keystone European forest tree species, including more than 150,000 trees sourced from 116 geographically diverse populations. The tests were planted on 23 field sites in six European countries, in order to expose them to a wide range of climates, including sites reflecting future warmer and drier climates. By assessing tree height and survival, our objectives were twofold: (1) to identify the source of differential population responses to climate (genetic differentiation due to past divergent climatic selection versus plastic responses to ongoing climate... |

| This paper examines the use of a neural network to analyse and predict the winter catch, in the Joban-Boso Seas off the Pacific coast of central Japan, of young Japanese sardine (Sardinops melanostictus) representing the index of recruits in the sardine stock. The supervised learning paradigm, a three-layer network and a back-propagation algorithm were employed in constructing the neural net. A number of biological, hydrographic and climatic factors constituted an input vector, the output being the catch of young sardine. The association of sardine abundance with environmental factors was quantified in the form of the trained neural network, which indicated important associations with the Southern Oscillation Index, with patterns of the Kuroshio and the... |

| The occurrence of El Nino causes tremendous havoc to economies. Recognizing this problem, the Philippine government has been introducing measures to mitigate the impact of the El Nino phenomenon. One of the measures to lessen the vulnerability of the farmers on El Nino related risk is the Small Water Impounding Projects (SWIPs). Furthermore, farmers have their own initiatives and coping mechanisms to mitigate the effects of El Nino. This research was undertaken to document the coping mechanisms, which would be useful in policy formulation. This study aims to: a) Determine the impacts of El Nino-related abnormal weather changes on agricultural production and farmers' income; b) Document the existing farming systems, resources, infrastructure, institutions,... |

| This second phase of the study is expected to produce actual and accurate information concerning socio-economic information and measures to cope with the El Nino effects at the farm level. Evidence of abnormal weather was apparent in Thailand in 2001 when the rain was less than the previous years' and the high temperatures were from January to March 2002. However, the rain came early in May 2002. Thus, the period of 2001 is suitable to represent an abnormal year for the study of the second phase of the project. The objectives of the second phase are to analyze and evaluate drought impacts at farm-household level, farmer's responses and government measures to overcome the problems. The research was conducted in two different provinces, namely Lop Buri in... |

| São duas as principais maneiras nas quais os efeitos do aquecimento global sobre o ciclo hidrológico nos trópicos pode afetar significativamente a demanda hídrica para culturas: O aumento da temperatura promovendo aumento da evapotranspiração, aumento da deficiência hídrica e o aumento dos períodos de estiagem. Há indicações de aumento da temperatura do ar e da duração dos veranicos sobre o Sertão de Pernambuco. Estudos recentes sobre o aquecimento global indicam que as mudanças climáticas poderão afetar a produção nacional e aumento das áreas de risco na Região Nordeste do Brasil (NEB). Nesse contexto, as análises das variações da duração e freqüência dos períodos de veranicos, bem como, a ocorrência de chuvas intensas, servirão como base para a detecção... |

| The objective of this study was to assess the effect of environmental variations on the abundance of Sardinella aurita and Sardinella maderensis in Senegalese waters in the upwelling system. Monthly data indicating the abundance of sardinella were first estimated from commercial statistics, using Generalized Linear Model from 1966 to 2011. Abundance indices (AIs) were then compared with environmental indices, at the local scale, a Coastal Upwelling Index (CUI) and a coastal Sea Surface Temperature (SST) index, and on a large scale, the North Atlantic Oscillation (NAO), the Atlantic Multidecadal Oscillation (AMO) and the Multivariate El Nino Southern Oscillation Index (MEI), using correlations and times series analyses. The results showed that the abundance... |

| E.A. Moya-Elizondo. 2013. Fusarium crown rot disease: biology, interactions, management and function as a possible sensor of global climate change. Cien. Inv. Agr. 40(2):235-252. Wheat crops are commonly affected by the dryland root rot complex (DLRRC) under dry and semiarid conditions. This complex is associated with seedling blight, and rotting of roots, crowns and stems of wheat plants. Several pathogens are associated with this complex, but Fusarium crown rot disease (FCR) is the most common and is of worldwide importance. Increased drought frequency and changes in rainfall regimes associated with global climate change may increase the prevalence of this complex of diseases, especially of FCR, in wheat crop areas. This review discusses the... |

| Coffee is one of the most heavily globally traded commodities and its production is based on Coffea arabica and Coffea canephora and Brazil being the world's largest coffee producer. It is believed that all this production will be affected due to climatic changes, with low flower viability, fruit development, yield and beverage quality. An alternative to assist in obtaining coffee plants more adapted to future climatic conditions would be genomic selection (GS). The implementation of these programs requires a lot of genetic markers, which are more readily discovered now after the reference genome of C. canephora became available. Another important factor is the high genetic variability of C. canephora, due to its level of allogamy, being of great... |

| Down-core samples of planktonic and benthic foraminifera were analyzed for oxygen and carbon isotopes in International Marine Past Global Changes Study (IMAGES) core MD99-2343 in order to study the interactions between climate change in the Northern Hemisphere and the western Mediterranean thermohaline circulation at times of Heinrich events (HE). Our results confirm the antiphase correlation between enhanced North Atlantic Deep Water formation and low ventilation in the Mediterranean. However, this study reveals that this antiphase relationship in deepwater formation between the North Atlantic and Mediterranean was interrupted during times of HE when the injection of large volumes of water from melting icebergs reached the entrance to the Mediterranean.... |
