Larix gmelinii (Rupr.) Kuzen. (Dahurian larch) is an important arctic tree-line species in the northern boreal forests of Eurasia. The region’s climate is predicted to change dramatically over the next century, yet little is known about how this species will respond to secular changes in temperature and precipitation. To this end, a ring-width chronology from 25 cores from a stand of seven Dahurian larch trees growing in the Secrest Arboretum, northeastern Ohio, was developed to test the climatic sensitivity of the species in a more temperate climate. The chronology extends from 1931 to 2005 and correlation analysis with monthly precipitation and temperature records shows growth was most strongly limited by summer precipitation until recent decades when sensitivity has shifted to late spring precipitation. The results from this study serve as a contemporary analog to the future growth response of Dahurian larch under warmer and wetter growing conditions in the boreal and arctic regions of Eurasia.

The aim of the study was to integrate economics, forage agronomy and livestock production data to determine the economic costs and benefits of management techniques that can extend the grazing season for beef production in Atlantic Canada. The results of the study show that extending the grazing season is financially and economically beneficial for both an Atlantic beef farmer and the whole Atlantic community. Extending the grazing season could be thus an alternative solution to enhance beef farm viability in Atlantic Canada. It can also contribute to the sustainable development of beef cattle production through its benefits for environmental protection. The results of this study reflect the necessity of supporting and promoting the adoption of extended grazing season practices in Atlantic beef production. This support and this promotion could involve increasing awareness, training on grazing management skills, diffusion at workshops and participatory research.

O tratamento biológico anaeróbio aparece como uma opção importante para remover a carga orgânica poluidora da vinhaça, e vem despertando interesse entre pesquisadores do mundo todo devido aos sucessos já alcançados, principalmente em trabalhos científicos. O interesse científico aponta para o aprimoramento do processo de degradação desse efluente em taxas elevadas, além de promover a produção de biogás, com potencial para produção de energia. A tecnologia de tratamento anaeróbio mais utilizada para o tratamento da vinhaça é o reator UASB, apresentando resultados satisfatórios inclusive em unidades em escala plena. A interrupção do funcionamento do reator em períodos de entressafra é, indubitavelmente, um problema a ser enfrentado na operação do reator UASB, cujo período de partida é lento. A repartida do sistema é agravada nos reatores de alta taxa, requerendo estratégias adequadas para reduzir o período necessário permitindo mitigar prontamente os efeitos do aporte de vinhaça ao ambiente e recuperar energia a partir dessa matriz. Diante disso, um reator anaeróbio de fluxo ascendente com manta de lodo (UASB) em escala piloto foi utilizado para o estudo da repartida do sistema e do tratamento da vinhaça e do melaço, sendo o último utilizado como fonte de carbono no período relativo à entressafra. O reator UASB foi operado durante 335 dias. Na Fase I utilizou-se a vinhaça como afluente, na Fase II o melaço de cana-de-açúcar e na Fase III novamente a vinhaça. Após período de interrupção de 30 dias, o período de repartida do sistema em estudo foi de 69 dias. Logo no início da repartida do reator, a eficiência de remoção de DQO foi superior a 80%, alcançando eficiência de 89,95 % em apenas oito dias de operação. O reator UASB apresentou valor médio de eficiência de remoção de DQO para as Fases I (vinhaça), II (melaço) e III (vinhaça) de 84 ± 3,35%; 82 ± 5,12% e 80 ± 9,22%, para cargas aplicadas de 5 a 34 kgDQO.m-3.d-1, 33 kgDQO.m-3.d-1 e 5 a 19 kgDQO.m-3.d-1, respectivamente. Em relação à produção de metano, de todo o período operacional, a Fase I referente à repartida do reator utilizando vinhaça como substrato após um mês sem alimentação foi a que apresentou a maior produção média no período, 7,93 LCH4. (L.d) -1, devido aos maiores valores de carga orgânica volumétrica (COV) aplicadas (5 a 34 kgDQO.m-3.d-1). A Fase II referente ao período de entressafra utilizando o melaço, foi de 7,28 LCH4. (L.d) -1 devido ao acúmulo de ácidos voláteis totais. A Fase III com retorno da safra utilizando a vinhaça, foi de 1,23 LCH4. (L.d) -1 devido aos menores valores de carga aplicada ao reator (5 a 8,5 kgDQO.m-3.d-1). As análises microbiológicas mostraram elevada diversidade microbiana e permitiu observar que com a utilização do melaço ocorreu alteração da população de microrganismos presente no reator, que apresentaram longo período de adaptação quando submetidos novamente à vinhaça, na última fase de operação. De forma geral, os resultados apontam que a tecnologia UASB é adequada no tratamento de vinhaça e melaço de alta carga orgânica e na geração de biogás. A substituição por melaço permitiu obter produção de biogás semelhante ao uso da vinhaça, entretanto dificultou a repartida, quando substituído pela vinhaça novamente (Fase III). / Biological anaerobic treatment systems are a promising approach for the removal of organic loading content of vinasse. Previous studies have demonstrated the optimization of the vinasse degradation process at high rates, promoting the biogas production with potential for energy use. Upflow anaerobic with sludge blanket (UASB) is the most applied anaerobic technology for the treatment of vinasse. Such reactor configuration presents satisfactory results even in full-scale units. The interruption of reactor operation during the off-season is undoubtedly an operational problem to be faced, whose restarting period is slow. The system restarting is intensified in high-rate reactors, requiring adequate strategies to reduce the time needed to mitigate the environmental effects of vinasse supply and to recover energy from that matrix. Therefore, a pilot-scale UASB was used to investigate the system restart and the treatment of vinasse and molasses. Sugarcane molasses was used as the carbon source during the off-season period. The system was operated during 335 days. The operational procedure consisted of three phases, in which different streams were used as carbon source: vinasse (Phases I), sugarcane molasses (Phases II) and vinasse (Phases III). After an interruption period of 30 days, the restarting period was 69 days. At the beginning of the restarting period, the average COD removal efficiency was higher than 80%, reaching COD removal efficiencies of 89.95% in only eight days of operation. The average COD removal efficiencies for Phases I (vinasse), II (molasses) and III (vinasse) were 84 ± 3.35%; 82 ± 5,12% and 80 ± 9,22%, respectively. Those removal efficiencies were achieved with organic loading rate 5 to 34 kgCOD.m-3.d-1 , 33 kgCOD.m-3.d-1 and 5 to 19 kgCOD.m-3.d-1, respectively. Regarding methane (CH4) production, Phase I (vinasse as substrate after one month without feeding) presented the highest average CH4 production (7.93 LCH4. (L.d) -1), due to the higher values of OLR (5 to 34 kgCOD.m-3.d-1). The CH4 production during Phase II (off-season using molasses as substrate) was 7.28 LCH4. (L.d) -1, due to the accumulation of volatile fatty acids (VFA). In Phase III, in which vinasse was applied again as substrate the CH4 production was 1.23 LCH4.(L.d)-1, due to the lower values of organic loading rate to the reactor (5 to 8.5 kgCOD.m-3.d-1). Microbiological analyses showed high microbial diversity in biomass developed at UASB reactor. Moreover, it was possible to observe that with molasses used as carbon source probably promotes changes in the microorganisms population, After period with molasses feeding, such microbiota presented a long adaptation period when resubmitted to vinasse, as the main carbon source in the feeding. In general, the results indicate that the UASB configuration was adequate for the vinasse and molasses treatment at high organic loading rate, resulting in high biogas production. In which the feeding with sugarcane molasses resulted in a biogas production similar to that obtained by vinasse feeding, but it made it difficult to divide when replaced by vinasse (Phase III).

Orientador: Luzia Helena Queiroz / Coorientador: Márcia Marinho / Banca: Cáris Maroni Nunes / Banca: Rafael Silva Cipriano / Resumo: A raiva é uma antropozoonose caracterizada por uma encefalomielite aguda, na grande maioria dos casos letal, com grandes impactos na saúde pública, economia e na medicina veterinária. No Brasil o número de casos de raiva transmitido por morcegos vem superando a transmissão por cães, representando um novo cenário epidemiológico desta zoonose. Objetivamos analisar o índice de positividade da raiva em morcegos, segundo as variáveis hábito alimentar, classificação taxonômica, sexo e estação do ano com o intuito de identificar possíveis fatores de risco para ocorrência da raiva em morcegos. Por meio da análise retrospectiva de registros de 10.362 amostras de mamíferos dos Laboratórios de Diagnóstico de Raiva e de Chiroptera da Unesp de Araçatuba, do período de 1998 a 2017, foram identificadas 6.389 amostras provenientes de quirópteros que foram submetidos ao diagnóstico de raiva e à identificação taxonômica. Obtivemos resultado positivo em 76 (1,1%) das amostras de quirópteros, provenientes de 10 espécies, dentre as 31 que foram enviadas, representando sete gêneros de três famílias. O perfil dos morcegos positivos para a raiva na região estudada foi caracterizado como insetívoros e frugívoros, pertencentes à família Vespertilionidae e gênero Myotis e Eptesicus. A época do ano com maior identificação do vírus da raiva em quirópteros foi a estação mais seca (entre os meses de maio a setembro). / Abstract: Rabies is an anthropozoonosis characterized by acute encephalomyelitis, which is lethal in the vast majority of the cases and has major impacts on public health, economy and veterinary medicine. In Brazil, the number of rabies cases transmitted by bats has been surpassing the transmission by dogs, representing a new epidemiological scenario for this zoonosis. The objective of this study was to analyze the positivity rate of rabies in bats, according to the variables alimentary habits, taxonomic classification, sex and season of the year, in order to identify possible risk factors for rabies occurrence in bats. A retrospective analysis of the records from Rabies and Chiroptera Diagnostic Laboratories of Araçatuba, from 1998 to 2017, identified 6,389 samples from Chiroptera that were submitted to rabies diagnosis and taxonomic identification. We observed positive result in 76 (1.1%) of the bats samples, from 10 species, out of the 31 that were sent, representing seven genera of three families. Thus, the profile of positive bats for rabies in the studied region was characterized as insectivorous and frugivorous, belonging to the family Vespertilionidae, and genus Myotis and Eptesicus. The time of year with the highest identification of the rabies virus in bats was during the dry seeson (between May and September). / Mestre

Lactation curves of dairy cows have been studied by dairy scientists for many years. The effects of various hereditary end non-hereditary influences on the lactation curve have been observed. Factors have been developed to standardize production to a common basis, correcting for differences in age, length of lactation, milking per day, gestation and environment.

For many years sportsmen have speculated that hunting limits pheasant populations. With the abolition of the Pheasant Game Farm program in Utah in 1953, this popular concept gained much impetus with the result that, because of public disfavor to a longer season, a 3 to 5 day season on pheasants is the maximum that bas been called in northern Utah and this only in areas classed as "better" pheasant habitat. In contrast to the short seasons in Utah, pheasant seasons in southern Idaho have been from 8½ to 15½ days long for the past 10 years, and will be even longer in 1956 (table 1). Since the topography and land-use patterns of southeast Idaho and northeast Utah are similar, the question has been asked by Cache County sportsmen, "how can Idaho maintain a 15½ day season in Franklin County, while just across the line here in Cache County, we have only a 3 to 5 day season?" Thus the purpose of this study was to investigate some of the factors affecting pheasant populations of northeast Utah and south-east Idaho under differing season lengths. Objectives of the study were to determine (1) the response of contiguous pheasant populations to long (15½ day) and short (5 day) seasons, (2) the hunting pressure under the 2 season lengths, (3) harvest of the pheasant crop under the 2 season lengths, and (4) reaction of hunters, farmers, and land-owners to long and short seasons.

Background: Several neuropsychiatrie disorders have shown season of birth associations. Low cerebrospinal fluid (CSF) levels of the serotonin metabolite 5-HIAA and the dopamine metabolite HVA have been associated with suicidal behaviour, impulsivity, and aggression. This thesis investigated associations between the season of birth, the CSF levels of three monoamine metabolites (including MHPG of norepinephrine), the scales of the diagnostic interview for borderline patients (DIB), and psychiatric diagnoses. Also, the methods of suicide were investigated in relation to the season of birth. Methods: We studied a clinical sample of 241 patients in Stockholm with mood, anxiety and adjustment disorders with respect to the CSF levels of monoamine metabolites in relation to the season of birth, and in relation to the DIB in an overlapping sample. We also analysed all completed suicides during the 42 years 1952- 1993inVästerbottenin northern Sweden (1466 cases) by multiple logistic regressions to relate suicide methods with season of birth, gender, age, urban-rural residence, marital status, year of suicide, and season of suicide. For the 20 years 1961- 1980 (693cases), psychiatric in-patient and out-patient records were also examined for any history of psychiatric contacts and psychiatric diagnoses. In two mutually independent samples, we investigated the DIB in relation to the season of birth. Results: In the Stockholm sample, those born during February to April had significantly lower CSF levels of 5-HIAA, and those born during October to January had significantly higher CSF levels of HVA, HVA/5-HIAA, and HVA/MHPG, as well as (non-significantly) higher levels of 5-HIAA. Those with an intermediate score of section II (impulse action patterns) of the DIB had significantly higher CSF levels of 5-HIAA and HVA, and they were significantly more likely to have been born during October to January. In the Västerbotten register, those born during February to April were significantly more likely to have preferred hanging rather than poisoning or petrol gases, and conversely for those born during October to January. These associations with suicide methods were found for the total sample and for those without any history of psychiatric contacts, but not for those with psychiatric contacts. Conclusions: Suicidal behaviour shows statistically significant variation according to the season of birth, most probably mediated by a variation in an independent trait of vulnerability to suicide based on neurodevelopmental parameters, particularly the serotonergic system. The suicidal process differs between those who seek psychiatric care compared to those who do not, reflecting differences in the diagnostic spectra and in the extent of mental illness. / <p>Härtill 6 delarbeten.</p>
