An analysis of natural factors of traffic accidents involving Yezo deer (Cervus nippon yesoensis) OAK
Kawata, Yukichika.
In Hokkaido, Japan, the number of Yezo deer (Cervus nippon yesoensis) has recently increased drastically, causing a large number of deer-vehicle traffic accidents. This paper examines conditions related to deer-vehicle traffic accidents by analysing the following relationships: time of accident and lunar phase; time of accidents and time of sunrise/sunset; likelihood of accidents and rainfall patterns, temperature and season (particularly snow and hunting seasons). The results suggest that the potential for deer-vehicle traffic accidents increases during hunting and non-snow seasons when there is little or no rainfall, just before sunrise or just after sunset, or during a full, first quarter, or third quarter moon. A statistically significant relationship...

Application of a microbial source tracking based on bacterial and chemical markers in headwater and coastal catchments ArchiMer
Jarde, Emilie; Jeanneau, Laurent; Harrault, Loic; Quenot, Emmanuelle; Solecki, Olivia; Petitjean, Patrice; Lozach, Solen; Cheve, Julien; Gourmelon, Michele.
This study identified sources of fecal contamination in three different French headwater and coastal catchments (the Justiçou, Pen an Traon, and La Fresnaye) using a combination of microbial source tracking tools. The tools included bacterial markers (three host-associated Bacteroidales) and chemical markers (six fecal stanols), which were monitored monthly over one or two years in addition to fecal indicator bacteria. 168 of the 240 freshwater and marine water samples had Escherichia coli (E. coli) or enterococci concentrations higher than “excellent” European water quality threshold. In the three catchments, the results suggested that the fecal contamination appeared to be primarily from an animal origin and particularly from a bovine origin in 52%...

Apport des donnees TRMM 3B42 a l´etude des precipitations au Mato Grosso. Repositório Alice
ARVOR, D.; DUBREUIL, V.; RONCHAIL, J.; MEIRELLES, M. S. P..
In tropical regions where convective rainfall is predominant while raingauge networks are deficient, satellite estimates as proposed by the Tropical Rainfall Measuring Mission (TRMM) can represent an efficient alternative way of studying rainfall spatiotemporal variability. A Principal Component Analysis based on monthly data allows mapping the various rainy regimes encountered in the south Amazonian state of Mato Grosso (Brazil). The TRMM 3B42 products are then validated based on statistical indexes. It permits determining an optimal 5-days temporal scale, which is then used to calculate rainy season parameters such as date of onset and end and duration. Those parameters are established based on the ?Anomalous Accumulation? method proposed by Liebmann...

Are Brazil nut populations threatened by fruit harvest? Repositório Alice
BERTWELL, T. D.; KAINER, K. A.; CROPPER JUNIOR, W. P.; STAUDHAMMER, C. L.; WADT, L. H. de O..
Harvest of Brazil nuts from the large, iconic tree Bertholletia excelsa generates substantial income for smallholders, providing a strong incentive to conserve the mature forests where it grows. Although much previous work has focused on the impact of nut harvest on new seedling recruits into B. excelsa populations, the connection between harvest rates and long-term population stability is still unclear. Moreover, there is additional uncertainty for Brazil nut management in terms of population response to climate change and other anthropogenic influences. We drew on 14 years of research in two sites in Acre, Brazil with different B. excelsa nut harvest intensities (39% and 81%), to produce stochastic and deterministic matrix population models which...

D.; SUSEELA, V.; TIETEMA, A.; VAN GESTEL, N.; VAN STRAATEN, O.; WAN, S.; WEBER, U.; JANSSENS, I. A..
As a key component of the carbon cycle, soil CO2 efflux (SCE) is being increasingly studied to improve our mechanistic understanding of this important carbon flux. Predicting ecosystem responses to climate change often depends on extrapolation of current relationships between ecosystem processes and their climatic drivers to conditions not yet experienced by the ecosystem. This raises the question of to what extent these relationships remain unaltered beyond the current climatic window for which observations are available to constrain the relationships. Here, we evaluate whether current responses of SCE to fluctuations in soil temperature and soil water content can be used to predict SCE under altered rainfall patterns. Of the 58 experiments for which we...

Characterization of water availability in a hydrographic basin REA
Arai,Fabiane K.; Pereira,Silvio B.; Gonçalves,Geula G. G..
The quantitative knowledge of hydrological parameters (rainfall and flow) and their spatial and temporal variability on the regions or basins should be understood as essential to the efficient planning and management of water resources. Because the Ivinhema Basin, located in the state of Mato Grosso do Sul, Brazil, represents an important inductor on the region agricultural development, characterized as a major producer of grains and meat, it was used to characterize the hydrological study. Knowing the rainfall, flow and drainage area of each of the studied affluent, it was calculated the proportion of contribution of the affluent. To that end, it was proposed the concepts of potential and real contributions, aiming to identify the proportion of...

Climate risk in maize crop in the northeastern of Brazil based on climate change scenarios REA
Silva,Vicente de P. R. da; Campos,João H. B. da C.; Silva,Madson T..
This study evaluates the impacts of climate change on the agricultural zoning of climatic risk in maize crop cultivated in the Northeastern of Brazil, based on the Intergovernmental Panel on Climate Change (IPCC) reports. The water balance model, combined with geospatial technologies, was used to identify areas of the study region where the crops could suffer yield restrictions due to climate change. The data used in the study were the time series of rainfall with at least 30 years of daily data, crop coefficients, potential evapotranspiration and duration of the crop cycle. The scenarios of the increasing of air temperature used in the simulations were of 1.5ºC, 3ºC and 5ºC. The sowing date of maize crop from January to March appears to be less affected...

Climatic risk for potato late blight in the Andes region of Venezuela Scientia Agricola
Garcia,Beatriz Ibet Lozada; Sentelhas,Paulo Cesar; Tapia,Luciano Roberto; Sparovek,Gerd.
Potato is an important crop for Venezuelan agriculture. However, its production is highly affected by late blight (Phytophtora infestans), since weather is commonly favorable for this disease. The aim of this study was to determine the sowing dates of low climatic risk for potato late blight in the Andes region of Venezuela, with an agrometeorological disease model and geographical information system (GIS) tools. The disease model used in this study was developed by Hyre (1954) which requires daily rainfall and temperature data which were obtained from 106 weather stations, located at the States of Mérida, Táchira, and Trujillo, for a period of 31 years. Hyre's model was applied for all stations obtainig the following variables: number of disease favorable...

Climatic risk zoning for corn and palisade grass (Brachiaria brizantha cv. Marandu) cultivated in integrated crop-livestock systems in São Paulo state, Brazil. Repositório Alice
SANTOS, P. M.; PEZZOPANE, J. R. M.; MENDONÇA, F. C.; BETTIOL, G. M.; EVANGELISTA, B. A.; SILVA, F. A. M. da.
Climatic risk zoning allows the identification of areas of low risk of reduced crop productivity due to climatic events. In Brazil, losses to agriculture due to climate are mainly caused by drought. The objective of this research was to determine areas of low climatic risk for corn and palisade grass cultivated in integrated crop-livestock systems in Sao Paulo state. Corn varieties characterized by a 120-day growing cycle and soil with three different water holding capacities (sandy, medium and clayey soils) were considered. A daily water balance model was used to simulate planting dates between September and December. The water requirement satisfaction index (WRSI) was calculated for critical phenological phases of both cultures (germination, emergence...

CLIMATOLOGICAL WATER BALANCE WITH DATA ESTIMATED BY TROPICAL RAINFALL MEASURING MISSION FOR THE DOCE RIVER BASIN REA
Louzada,Franciane L. R. de O.; Xavier,Alexandre C.; Pezzopane,José E. M..
ABSTRACT The Climatic Water Balance (CLIMWB) is very used in the climatic characterization and can also offer important contribution in the identification of the water demand for irrigation of a region. For this, reliable precipitation data with good spatial coverage is required. The Tropical Rainfall Measuring Mission satellite -TRMM-3B43-v7 is a partnership between NASA (National Aeronautics and Space Administration) and Japan's Aerospace Exploration Agency (JAXA), which estimates rainfall data for the tropics region. The aim of this study is to evaluate the CLIMWB obtained by the Thornthwaite & Mather method (1955), with estimated rainfall data with the 3B43 product versus those generated with rainfall data and to map pixel-by-pixel water...

MASCHIO, L. M. A.; ANDRADE, F. M.; AUER, C. G..
Um estudo foi desenvolvido para verificar o efeito de fatores climáticos sobre a ocorrência da seca de ponteiros do eucalipto da região de Arapoti, PR, Brasil (SPEA), em Eucalyptus grandis. A temperatura e a precipitação pluviométrica dos anos com incidência da SPEA foram registradas para estabelecer uma relação entre as condições climáticas e a doença. A SPEA foi severa em períodos com temperaturas elevadas e chuvas pouco intensas e bem distribuídas. A doença ocorreu, também, em períodos de chuvas intensas, com menor intensidade de sintomas. Foi observado que períodos de baixa temperatura podem reduzir ou minimizar a incidência da SPEA

Daily rainfall variability at a local scale (1,000 ha), in Piracicaba, SP, Brazil, and its implications on soil water recharge Scientia Agricola
Reichardt,K.; Angelocci,L.R.; Bacchi,O.O.S.; Pilotto,J.E..
Daily rainfall variability at a local scale (1,000 ha) was studied at Piracicaba, SP, Brazil, for the period of one year (1993-1994), in order to better understand the process of soil water recharge. Coefficients of variation of daily data for ten observation points varied from 2.2 to 169.3% and the variability was independent of rain type, i.e. whether convective, frontal or of other origin. Data were not related to separation distances between observation points and it is concluded that one observation point does not represent areas as far as 1,000 to 2,500 m apart, for daily, monthly or even quarterly averages. Yearly totals for the ten observation points presented a coefficient of variation as low as 3.06%, indicating that all points can replace each...

Diurnal variability of rainfall in southwest Amazonia during the LBA-TRMM field campaign of the austral summer of 1999 Acta Amazonica
Marengo,José A.; Fisch,Gilberto; Morales,Carlos; Vendrame,Iria; Dias,Paulo C..
The TRMM-LBA field campaign was held during the austral summer of 1999 in southwestern Amazonia. Among the major objectives, was the identification and description of the diurnal variability of rainfall in the region, associated with the different rain producing weather systems that occurred during the January-February season. By using a network of 40 digital rain gauges implemented in the state of Rondônia, and together with observations and analyses of circulation and convection, it was possible to identify details of the diurnal cycle of rainfall and the associated rainfall mechanisms. Rainfall episodes were characterized by regimes of "low-level easterly" and "westerly" winds in the context of the large-scale circulation. The westerly regime is related...

Do precipitation and food affect the reproduction of brown brocket deer Mazama gouazoubira (G. Fischer 1814) in conditions of semi-captivity? Anais da ABC (AABC)
Juliá,Juan P.; Peris,Salvador J..
The births of brown brocket deer ( Mazama gouazoubira) in a secondary lower montane forest called "yunga" in northwestern Argentina were compared with rainfall. Analyses were performed with rainfall and flower-fruit fall in an attempt to determine the possible importance of these seasonal variables in birthing. The births were not directly correlated with rainfall, but rather with the flower and fruit fall of exotic plant species. This may be related to favor the development of fawns, which eat the new and more digestible plant parts, accessible one month after their births.The non-seasonal births observed around the year could be related to the selection by the deer of some plant species that have been introduced into the region ( Prunus, Morus and...
