1. Deslocamento do abomaso em bovinos no Estado de Pernambuco: fatores de risco, aspectos clínicos, laboratoriais e avaliação terapêutica
The continuous genetic selection for high milk production in association with greater digestive capacity and corporal depth increases the susceptibility for abomasopathies including abomasal displacement. The present work aimed to accomplish a retrospective study on abomasal displacement in 36 cattle attended at Bovine Clinic, Garanhuns Campus, Federal Rural

4. Ecologia e comportamento de formigas tecelÃs (Camponotus) no cerrado brasileiro
The form of nests construction in eusocial insects reveals important steps of its evolutionary history. The weaver ants nests are built starting from the silk that is produced by their own larvas. This form of nests construction is one of the most remarkable instances of social cooperation in animals. The nests construction behavior in the weavers limited to

5. Mutually exclusive muscle designs: the power output of the locomotory and sonic muscles of the oyster toadfish (Opsanus tau).
Animals perform a vast array of motor activities. Although it has generally been accepted that muscles are well suited to the function that they must perform, specialization for performing one function may compromise their ability for carrying out another. We examined this principle in the toadfish muscular system: slow-twitch red and fast-twitch white myoto
