1. Predatory behavior of three centipede species of the order Scolopendromorpha (Arthropoda: Myriapoda: Chilopoda)
ABSTRACT Studies related to centipede feeding and predatory behavior are rare in the literature, and are limited to observations made during fieldwork. Furthermore, they lack descriptions of prey capture. We conducted a laboratory experiment using South American specimens of Scolopendra viridicornis Newport, 1844 (n = 5), Otostigmus tibialis Brölemann, 1902

2. The predatory memory of the spider Argiope argentata: prey localization and size / Memória predatória da aranha Argiope argentata: localização e tamanho da presa
Orbweb spiders perform searching movements when a prey attached to the hub or hoarded at the periphery of the web is suppressed. We here examined the question of a possible memory representation of the attachment site and of prey size in three experiments with Argiope argentata (Fabricius, 1775). In Experiment 1, we looked for differences between search sequ

3. Comportamento predatório de serpentes Boidae de diferentes hábitos e biometria de Eunectes murinus Linnaeus, 1758 em laboratório / Predatory behavior of boas of different habits, and biometry of Eunectes murinus Linnaeus, 1758 in laboratory.
Diferentes formas, de adquirir alimento foram desenvolvidas dentro do grupo das serpentes. Estratégias de obtenção de alimento podem estar relacionadas aos microhabitats de cada espécie. Este estudo objetivou comparar o comportamento predatório de Eunectes murinus (semiaquática) (n=4), Corallus hortulanus (arborícola) (n=2) Boa constrictor (semiarbor�

4. Ecologia comportamental de Pachycondyla marginata (Roger) (Hymenoptera : Formicidae) : predação em grupo e habito migratorio
This study investigates the group-raiding behavior and migratory habit of the neotropical ant Pachycondyla marginata. Field work was carried out in the semideciduous forest of the Reserva Municipal de Santa Genebra, Campinas, SP. A total of 202 group-raid of termite nests was observed from February 1991 to September 1993. Pachycondyla marginata preyed exclus

5. Forrageamento de aranhas de teia orbicular : influencia do tamanho da presa e local de contato na teia
Tbe foraging behavior of tbe orb-weaving spiders Micrathena nigrichelis (Araneidae), with a vertical orb and Leucauge sp. (Tetragnathidae), with an inclined web -(458) was studíed. Stimulations witb a tunning fork were done, to test the hipothesis that the assimetry of tbe webs can be explained by temporal parameters of the predatory response of spiders (fu

6. Cost-benefit analysis potential in feeding behavior of a predatory snail by integration of hunger, taste, and pain
Hunger/satiation state interacts with appetitive and noxious stimuli to determine feeding and avoidance responses. In the predatory marine snail Pleurobranchaea californica, food chemostimuli induced proboscis extension and biting at concentration thresholds that varied directly with satiation state. However, food stimuli also tended to elicit avoidance beha

7. The evolution of reproductive restraint through social communication
The evolution of altruistic behavior through group selection is generally viewed as possible in theory but unlikely in reality, because individual selection favoring selfish strategies should act more rapidly than group selection favoring cooperation. Here we demonstrate the evolution of altruism, in the form of conditional reproductive restraint based on an
