| Africanized honeybees from five colonies were marked with P-32 and taken to an apple grove for a flight behavior study. The method used to determine the flight range was to put out an array of tagged trees in a cross pattern with the colonies arranged in the center point of a 0.8 ha test area. The tagged trees were located 10 meters apart in the 4 rows of 50 meters each, arranged according to the North, South, East, and West directions. Bees were collected while visiting the tagged tree flowers twice a day, during a ten-day period. The number of honeybees marked decreased in relation to the distance from the hives. Analysis of variance showed that a linear regression was highly significant to describe the process. Geographic directions did not affect the... |

| The northern coast of Pernambuco State, Brazil, is an wintering area for shorebirds originally from north America, especially from the east. The first flocks arrive in September, staying till April, when they molts, change plumage, and acquire enough biomass to migrate back to the northern hemisfere. In order to calculate flight range mass and length of the wing of Charadrius semipalmatus Bonaparte, 1825, Calidris fuscicollis Vieillot, 1819, C. pusilla Linnaeus, 1766 and C. alba Pallas, 1764 was recorded. Traps were carried out in Coroa do Avião (7º40' S and 34º50'W) in the northern coast of the State of Pernambuco, between May 1992 and April 1995. The length of the wing was registered with the wing spread (from the insertion of the bone till the extremity... |
