Resumo: Objetivou-se descrever o crescimento de ovinos Santa Inês no Vale do Gurgueia a partir da análise de modelos não lineares: Brody,Von Bertalanffy, Richards, Logístico e Gompertz. Após a definição do modelo de melhor ajuste, avaliou-se a influência de fatores ambientais (estação de nascimento, sexo, tipo de parto e idade da mãe ao parto) sobre os parâmetros da curva. Foram utilizados dados do desenvolvimento ponderal de 61 ovinos, do nascimento aos 350 dias de idade, no período de janeiro de 2009 a dezembro de 2010. Os parâmetros foram estimados por meio do NLIN do SAS. Os modelos de Von Bertalanffy, Richards, Logístico e Gompertz ajustaram bem os dados de crescimento, entretanto, os modelos de Brody e Richards apresentaram maior variação no Quadrado Médio dos Resíduos. Com base no gráfico de dispersão dos resíduos, constatou-se que o modelo de Gompertz apresentou ajuste ligeiramente superior ao modelo de Von Bertalanffy. A taxa de crescimento absoluto estimada demonstrou crescente até os 28 dias de idade. O efeito de sexo foi importante fonte de variação para o parâmetro A, bem como os efeitos de idade da mãe ao parto aos parâmetros B e K. As correlações estimadas entre os parâmetros A e K, B e K foram negativas. Efeitos ambientais mostraram-se importantes fatores que influenciam os parâmetros da curva de crescimento de ovinos Santa Inês no estado do Gurgueia.

The objective of this study was to analyze nonlinear models between Brody, Von Bertalanffy, Richards, Logistic and Gompertz, that best fit to describe the growth of Santa Ines sheep in Valley Gurguéia and, after setting the best model, it was to evaluated the influence of environmental factors (season of birth, sex, type of birth and mother's age at birth) on the parameters of the curve. Data were obtained from 61 sheep weight development from birth to 350 days of age from January 2009 to December 2010. The parameters were estimated using the SAS NLIN procedure. The models of Von Bertalanffy, Richards, Logistic and Gompertz fit the data well for growth, however, greater variation in Mean Square Waste was seen for Brody and Richards models. Based on the scatter plot of the waste, it was found that the Gompertz model presented set slightly higher than the model of von Bertalanffy. The estimated rate of absolute growth showed increased up to 28 days old. The effect of sex was an important source of variation for the parameter A, as well as the effects of age of mother at birth to the parameters B and K. The estimated correlations between the parameters A and K, B and K were negative. Environmental effects were important factors influencing the parameters of the growth curve of Santa Inês sheep in the state of Gurguéia.

Summary: Coffee crop has been predicted to become threatened by future climate changes and global warming conditions. Yet, the long-term effects of elevated [CO2] on this plant remain to be fully elucidated. In this context, this work aims at linking coffee biochemical responses to environmental changes of [CO2] and temperature on genotypes from the two major producing species, using the photosynthetic metabolism as probe to evaluate the plant acclimation ability. Potted plants from C. arabica cv. IPR 108 and of C. canephora cv. Conilon Clone 153 were grown under environmental controlled conditions, either at 380 or 700 ?L CO2 L-1 air, for 1 year, without water, nutrient or root development restrictions. After that the temperature was gradually increased from 25/20 ºC (day/night) up to 42/34 ºC. The effects of elevated [CO2] and enhanced temperature on the photosynthetic structures were assessed through the characterization of the lipid components of chloroplast membranes, whereas the leaf metabolic performance was evaluated through the thylakoid electron transport rates (involving both photosystem (PS) I and II), and the activities of enzymes (ribulose 1,5-biphosphate carboxylase/oxygenase and ribulose 5-phosphate kinase), as well as through stable isotopes of C and N. The activities of respiratory enzymes (NADH-dependent malate dehydrogenase and pyruvate kinase) were also analyzed. The results pointed for a higher functional status along the experiment in the plants grown under elevated [CO2], with special relevance at 37 and 42ºC in IPR108. These results could be related to the qualitative changes of the membrane lipid matrix that might have helped to preserve suitable membrane fluidity for the membrane bound events (e.g., thylakoid electron transport). The PSs and enzyme data reflect an enhancement of the energetic metabolism (both photosynthesis and respiration), mostly, until 31 ºC for IPR108 and 37 ºC for CL153 at normal [CO2]. Yet, under enhanced [CO2] it was found an increase in the temperature (to 37 ºC) at which maximal values of some parameters in IPR108 (MDH, PSs activities, RuBisCO) were observed, concomitantly with the maintenance of high performance in other parameters when compared to the 380 plants. Under the highest temperature (42 ºC) the enzymes were the most sensitive point, displaying the strongest reductions, irrespective of genotype and [CO2] treatments. The temperature promoted changes in leaf ?13C, irrespective of genotype and [CO2], reflecting a decrease in WUE with heat. The changes in ?15N values may indicate different limitation steps of N assimilation, requiring further investigation. It was concluded that the coffee plants grown under elevated [CO2] apparently showed a better endurance to high temperatures, what is quite relevant in a context of predicted climate changes and global warming scenarios.
