| Jiggs bermudagrass has presented competitive production potential over other forages. However, there is a lack of information about the nutritional value of this forage with important relevance in ruminant nutrition. This study aimed to evaluate the protein and carbohydrate fractionation of Jiggs bermudagrass in different seasons of the year under intermittent grazing by Holstein cows. The experiment was conducted during one year in a completely randomized design with nine replications and treatments consisted of the effect of four seasons: fall, winter, spring and summer. The results showed that there were seasonal variations in the fractions of proteins and carbohydrate, with the exception of the protein fraction B3. The better climatic conditions in... |

| Flight activity of Melipona bicolor bicolor, coming from Cunha (23º05'S, 44º55'W), Atlantic Forest, was studied in ten colonies, and in two periods: from July to September 1993 and from August to September 1995. The colonies were grouped in weak, medium and strong, according to the diameter of the combs, which can provide a good idea of the number of cells built. 855 observations were accomplished for 5 minutes, every half-hour, from 8 to 18 hours. The total number of bees that entered and left the hive and the number of bees that arrived with mud, pollen and resin, besides the number that went out with debris in that period were counted. It was also registered the temperature and the relative humidity of the air. The total external activity, as well as... |

| Brazil is the second soybean (Glycine max L. Merrill) producer and exporter in the world. In 2005, soybean cultivated in the southeastern region of the country suffered drought stress imposed by adverse high temperatures and low humidity during its reproductive stage. Little information is available regarding the effect of drought stress on the quality of grains. In this study chemical and biochemical characteristics of five soybean samples belonging to three different cultivars grown under drought stress were evaluated. The samples did not meet standards for marketing and contained high amounts of green seeds. Grains were analyzed for appearance, 100 seed weight, humidity, water activity, proteins, lipids, lipoxygenase 1 activity, peroxides, and pigment... |

| ABSTRACT This study evaluated the influence of the environment and of two models of beehive (wooden box and ceramic pot) on the flight activity of the ground-nesting bee, Melipona quinquefasciata. The experiment took place in the Chapada do Araripe, in the State of Ceará, Brazil, between July 2014 and June 2015. The study followed colonies in three ceramic pots and four wooden boxes. Observations of the flight activity of the bees and of the climate were made on five days every month, each colony being monitored for 5 min, at intervals of one hour, from 0500 to 1700. The internal temperature and relative humidity of the hives were also recorded every hour throughout the year. The temperature correlated positively with the bees' entering and leaving the... |
