Some aspects of predatory behavior

Aggressive Behavior, 1978
Predatory 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.

Predatory behavior in the genusLeptogenys: A comparative study

Journal of Insect Behavior, 1997
We studied the predatory behavior of seven species of the genusLeptogenys from Mexico and Cameroon. The ants of this genus are armed with long, thin, curved mandibles articulated at the extreme corners of the anterior margin of the head, permitting them easily to seize oniscoid isopods, the obligate or the principal prey of mostLeptogenys species ...

Speculation and Predatory Behavior

2017
As 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, 1978
Evidence 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 ...

Defensive behavior in rats towards predatory odors: a review

Neuroscience & Biobehavioral Reviews, 2001
Studies of the response of rodents to predatory odors (mainly cat) have provided useful insights into the nature of defensive behavior. This article reviews work in this area with a focus on a behavioral paradigm recently developed in our laboratory in which we present rats with a piece of fabric collar that has been previously worn by a cat.

Form and function: the phylogenesis of predatory behavior.

Australian Mammalogy, 1985
The act of predation is defined here to include the behavior of insectivores. By examining the behavior of a set of morphologically conservative mammals, a common pattern of prey capture can be identified. Mammals with a conservative morphology and that are active predators may have similar bite efficiencies. Acts of predation in nature are only rarely

Predatory Behaviors in Bacteria — Diversity and Transitions

Microbe Magazine, 2007
Nutrient and energy flows among organisms can be depicted as webs within which predatory interactions are extremely important. Predatory behaviors often dominate top-to-bottom relationships, while productivity tends to control bottom-to-top flows.

Predatory Behavior of Argiope aurantia (Lucas)

American Midland Naturalist, 1974
The 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 ...

Multimodal Integration in the Feeding Behaviors of Predatory Teleost Fishes

Brain, Behavior and Evolution, 2002
The search for useful model systems to study sensory processing in vertebrate nervous systems has resulted in many neuroethological studies investigating the roles played by a single sensory modality in a given behavior. However, animals behaving in a complex, three-dimensional environment receive a large amount of information from external and ...

Optimal diet theory: behavior of a starved predatory snail

Oecologia, 1987
The tenets of optimal foraging theory are used to contrast the behavior of the predatory snail Acantina spirata when feeding on the barnacles Balanus glandula and Chthamalus fissus under conditions of satiation and starvation. As predicted in optimal diet models, A.
