O conteúdo estomacal de 137 exemplares de Potamotrygon motoro provenientes de 3 localidades (Muaná, Afuá e Lago Arari) na ilha de Marajó foi analisado. Os valores do Índice Relativo de Importância (IRI) e respectiva porcentagem (%IRI) foram calculados. O nível de repleção 1 (¼ cheio) foi o mais representativo para ambos os sexos, assim como para exemplares imaturos e maduros. A maioria dos itens alimentares analisados encontrava-se bastante digerido. A identificação dos itens alimentares indicou a presença de 15 ordens, incluindo insetos, moluscos, crustáceos, anelídeos e peixes. Diferenças na dieta entre os locais amostrados foram observadas ao se comparar as %IRI, sendo crustáceos o item preferencial em Afuá, peixes no Lago Arari e moluscos em Muaná.

No presente trabalho foram avaliados os elementos ambientais: temperatura do solo, temperatura e umidade relativa do ar, nas condições de ambiente protegido (coberto com polietileno) e de campo, num período sem cultura (solo sem cobertura vegetal) e num outro com a cultura do pimentão, em anos diferentes, nas condições climáticas de Botucatu, SP. O híbrido de pimentão utilizado foi o Margarita, que apresenta frutos vermelhos quando maduros. A temperatura do solo foi monitorada por dois sensores eletrônicos instalados a 0,1m de profundidade, sendo um na condição de ambiente protegido e outro na condição de campo, e a temperatura e umidade do ar foram monitoradas por dois sensores eletrônicos instalados a 2m de altura (ambiente protegido e campo). O efeito do pimentão alterando o microclima de cultivo foi observado na temperatura do solo, que apresentou menores valores do índice no período com a cultura, uma vez que o dossel funcionou como uma barreira física que impediu que a radiação solar chegasse ao solo. Os valores encontrados para o índice da temperatura e umidade relativa do ar no período sem a cultura foram muito próximos aos encontrados no período com a cultura, não caracterizando o efeito do pimentão sobre essas variáveis.

Physiological responses like the thermal requirements for germination may be influenced during seed formation by environmental conditions such as water availability and temperature. Here we analyzed germination of embryos of Ingavera subsp. affinis from different sources in response to various temperature regimes, including calculation of degree days and accumulated rainfall during development and maturation. Embryos were taken from ripe fruits collected on trees located in São Paulo and Minas Gerais, and were analyzed as to germination, water content and dry matter content. The results showed that the origin of the embryos was related to variation in response under sub-optimal temperatures. Depending on the origin, I.vera subsp. affinis embryos were able to germinate even at low temperatures (10 to 15 ºC), with better performance attained from 20 to 25 ºC. This variation may be associated, among other factors, to environmental conditions during maturation and to the maturation stage at seed dispersal.

OBJECTIVE: The purpose of the study was to evaluate the influence of the skeletal maturation in the mandibular and dentoalveolar growth and development during the Class II, division 1, malocclusion correction with Balters bionator. METHODS: Three groups of children with Class II, division 1, malocclusion were evaluated. Two of them were treated for one year with the bionator of Balters appliance in different skeletal ages (Group 1: 6 children, 7 to 8 years old and Group 2: 10 children, 9 to 10 years old) and the other one was followed without treatment (Control Group: 7 children, 8 to 9 years old). Lateral 45 degree cephalometric radiographs were used for the evaluation of the mandibular growth and dentoalveolar development. Tantalum metallic implants were used as fixed and stable references for radiograph superimposition and data acquisition. Student's t test was used in the statistical analysis of the displacement of the points in the condyle, ramus, mandibular base and dental points. Analysis of variance one-fixed criteria was used to evaluate group differences (95% of level of significance). RESULTS: The intragroup evaluation showed that all groups present significant skeletal growth for all points analyzed (1.2 to 3.7 mm), but in an intergroup comparison, the increment of the mandibular growth in the condyle, ramus and mandibular base were not statically different. For the dentoalveolar modifications, the less mature children showed greater labial inclination of the lower incisors (1.86 mm) and the most mature children showed greater first permanent molar extrusion (4.8 mm).

It was evaluated the influence of rootstocks 'IAC 766', 'IAC 572', 'IAC 313', 'IAC 571-6' and 'Ripária do Traviú' and the pruning periods in the duration of phenological stages and in the accumulation of degree-days on grape 'Niagara Rosada' .The experiment was conducted in Louveira, SP. The treatments consisted of five rootstocks and three times of pruning, the experimental design being used in a completely randomized split plot with five replications, and plots represented by rootstocks and the subplots were pruning. After pruning the grapevine, were realized evaluations for phenological stages, using the criterion of Eichhon e Lorenz (1984). ). In three seasons of pruning, based on phenological stages, it was calculated the length of the periods: pruning to budding, pruning to the beginning of the flowering, pruning to the beginning of fruiting, pruning to beginning of ripening of the bunches, pruning the beginning of the harvest. Taking as a basis the cycle length of the vine and the average daytime temperatures, it was calculated the accumulation of degree-days. Data were submitted to ANOVA and Tukey test at 5% significance level. It was obtained in the summer pruning the reduction in duration of the phenological stages of 'Niagara Rosada' grafted on the rootstock 'Ripária Traviú'. The longer duration of the cycle and accumulation of degree-day of 'Niagara Rosada' cultivar were obtained with the rootstocks 'IAC 572' and 'IAC 313' pruning in the winter.
