Predatory digging behavior by dinosaurs
Geology, 2010Minimal direct evidence exists in the rock record of dinosaurs and mammals behaving as predators and prey, respectively. A newly discovered Late Cretaceous trace fossil association of digging traces of maniraptoran theropod dinosaurs and mammalian den complexes indicates a predator-prey relationship. Three distinct associated trace fossils occur within

Antidepressants and the control of predatory behavior
Physiology & Behavior, 1980Abstract The problem is raised whether the concept of the pharmacological control of predatory behavior of the rat (muricide) does apply to a carnivorous species, the ferret. Antidepressant drugs with differential potencies on either noradrenaline and/or serotonin uptake were applied: Fluoxetine (6 and 12 mg/kg orally), chlorimipramine (15 mg/kg ...

Predatory behavior after hypothalamic lesions in cats
Physiology & Behavior, 1980Abstract Electrolytic lesions of the hypothalamus were performed in cats tested preoperatively as good mouse killers. It was found that mouse killing behavior was not impaired after hypothalamic damage, whereas mouse consumption was abolished for several weeks.

Detecting Predatory Behavior in Game Chats
IEEE Transactions on Computational Intelligence and AI in Games, 2015While games are a popular social media for children, there is a real risk that these children are exposed to potential sexual assault. A number of studies have already addressed this issue, however, the data used in previous research did not properly represent the real chats found in multiplayer online games.

Some aspects of predatory behavior
Aggressive Behavior, 1978Predatory behavior is conceived of as a loose chain of responses including searching for relevant stimuli, hunting or chasing potential prey, capturing or attacking prey, and killing and feeding on prey. These aspects, which may occur independently, are described and discussed separately with an emphasis on mammalian species of carnivores.

Speculation and Predatory Behavior
2017As the result of multiple wars and a high infant mortality rate for males, some women were driven to extremes in order to secure a place for themselves on the marriage market. The speculating minor women are often prettier and more vibrant than the heroines, but their intrinsic value is often tarnished.

The roots of primate predatory behavior
Journal of Human Evolution, 1978Evidence is examined that supports the view that in collecting-predatory primates many of the behaviours associated with the predatory component of the subsistence pattern are similar to those occurring during omnivorous collecting activities. General similarities are found between some elements of predatory behavior and some overall features of ...

Predatory Behavior of Argiope aurantia (Lucas)
American Midland Naturalist, 1974The impact of an insect in the orb web of Argiope aurantia elicits a complex sequence of predatory behavior which can be subdivided on a functional basis into four categories: prey location, prey immobilization, prey transportation and feeding. This paper de- scribes the more common predatory behavior patterns of a Central Texas population of this ...

Predatory versus alimentary behavior after amygdala lesions in cats
Physiology & Behavior, 1978Abstract In cats the effort of small amygdala lesions on mouse-killing behavior and food intake was studied. After ventromedial amygdala lesions predatory behavior was abolished for several weeks whereas food intake was only slightly diminished. Lesions of dorsolateral amygdala did not impair the effective predatory behavior, but produced a decrease ...

Behavioral Diversity of Predatory Arboreal Ants in Coffee Agroecosystems
Environmental Entomology, 2008Abstract Aspects of predator assemblages that alter predator effects on prey have received extensive recent attention. Among other mechanisms, differences in behavior or resource use within predator trophic levels may enhance predator effects on prey, especially if effects of each predator species differ with environmental conditions. We
