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%...

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 characteristics of the 2010-2016 drought in the semiarid Northeast Brazil region Anais da ABC (AABC)
MARENGO,JOSÉ A.; ALVES,LINCOLN M.; ALVALA,REGINA C.S; CUNHA,ANA PAULA; BRITO,SHEILA; MORAES,OSVALDO L.L..
ABSTRACT This study discusses the climatological aspects of the most severe drought ever recorded in the semiarid region Northeast Brazil. Droughts are recurrent in the region and while El Nino has driven some of these events others are more dependent on the tropical North Atlantic sea surface temperature fields. The drought affecting this region during the last 5 years shows an intensity and impact not seen in several decades in the regional economy and society. The analysis of this event using drought indicators as well as meteorological fields shows that since the middle 1990s to 2016, 16 out of 25 years experienced rainfall below normal. This suggests that the recent drought may have in fact started in the middle-late 1990s, with the intense droughts...

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 R. Bras. Zootec.
Santos,Patrícia Menezes; Pezzopane,José Ricardo Macedo; Mendonça,Fernando Campos; Bettiol,Giovana Maranhão; Evangelista,Balbino Antônio; Silva,Fernando Antônio Macena 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...

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...

ECONOMIC AND ENVIRONMENTAL BENEFITS OF VARIABLE RATE APPLICATION OF NITROGEN TO CORN FIELDS: ROLE OF VARIABILITY AND WEATHER AgEcon
English, Burton C.; Mahajanashetti, S.B.; Roberts, Roland K..
The use of meta-response functions based on EPIC-generated data resulted in comparisons between variable (VRAT) and uniform rate application technologies for 36 simulated fields. VRAT was more profitable and less nitrogen was lost to the environment in most cases. When spatial variability was small, uniform rate application techniques were adopted. However, when nitrogen use is restricted, VRAT is used on all simulated fields.

Efficacy and limitations of triticale as nitrogen catch crop in a Mediterranean environment IPB - Escola Superior Agrária
Rodrigues, M.A.; Coutinho, João; Martins, F..
During 3 consecutive years (1996/97–1998/99) the efficacy was studied of Triticale as a nitrogen (N) catch crop sown after the harvest of the potato crop cultivated in the preceding summer season under several N fertilizer treatments. In October, shortly after the harvest of the potatoes, there were registered significative differences in the soil N–NO3− levels among N fertilizer treatments of the potato crop. The higher values were recorded on the plots corresponding to higher N doses. At the end of winter, the N status of plants and at the end of experiments (late in April), the N–NO3− in soil, the biomass yield and the N uptake by the catch crop did not reflect the differences registered before in the soil inorganic N. This comparison may suggest that...

Estimation of climatological water deficit in an experimental watershed in the brazilian cerrado REA
GOTARDO,JACKELINE T.; RODRIGUES,LINEU N.; GOMES,BENEDITO M..
ABSTRACT This study aimed to estimate the probability of climatological water deficit in an experimental watershed in the Cerrado biome, located in the central plateau of Brazil. For that, it was used a time series of 31 years (1982–2012). The probable climatological water deficit was calculated by the difference between rainfall and probable reference evapotranspiration, on a decennial scale. The reference evapotranspiration (ET0) was estimated by the standard FAO-56 Penman-Monteith method. To estimate water deficit, it was used gamma distribution, time series of rainfall and reference evapotranspiration. The adherence of the estimated probabilities to the observed data was verified by the Kolmogorov-Smirnov nonparametric test, with significance level...

Implications of climate change on the management of Rift Valley lakes in Kenya. The case of lake Baringo OceanDocs
Ngaira, Josephine K..
Climate patterns of the World became very variable during the last half of the twentieth century. Causes of this variability/change have been identified as: Sun Spot activity, ozone depletion, decline in the solar beam, with the more pronounced especially in Africa being Increased atmospheric carbondioxide, and albedo change due to anthropogenic factors. The most affected weather elements by the above mentioned factors particularly in the tropics are Rainfall and Temperature, and the climatic environments most affected by the named weather elements are the arid and semi-arid lands which are already moisture constrained. The rift valley in Kenya, where most of the lakes are located experience Arid and Semi-Arid climate. The lakes located in this region are...
