Predatory behavior under monocular and binocular conditions in the semiterrestrial crab Neohelice granulata [PDF]
Frontiers in Behavioral Neuroscience, 2023 IntroductionNeohelice granulata crabs live in mudflats where they prey upon smaller crabs. Predatory behavior can be elicited in the laboratory by a dummy moving at ground level in an artificial arena.

Behavioral and Epileptic Determinants of Predatory Attack Behavior in the Cat [PDF]
Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 1975 SUMMARY:This report presents studies which relate limbic epileptic excitability to behavioral measures of defensive suppression of predatory attack in cats. Correlated with heightened defensiveness to environmental stimuli among non-killer cats is a heightened amygdaloid epileptic excitability, as well as a heightened conduction of amygdaloid epileptic

The predatory behavior of Pheidole megacephala/ [PDF]
Comptes Rendus. Biologies, 2007 We studied the foraging and predatory behaviors of the invasive African myrmicine ant, Pheidole megacephala (F.) in its native range. Workers can singly capture a wide range of insects, including relatively large prey items. For still larger prey, they recruit at short range those nestmates situated within reach of an alarm pheromone and together ...

Predatory behavior in two strains of laboratory mice [PDF]
Psychonomic Science, 1969 Eighteen C57BL/Crgl and 12 IS/Bi/Crgl male mice, not deprived of food, attacked and ate crickets on two occasions. In comparison with ISs, C57BL mice had longer attack latencies on both trials, spent their initial minutes in more approach-withdrawal behavior, and showed a significant decrease in attack latency on Trial 2.

Lateralization of eye use in cuttlefish: opposite direction for anti-predatory and predatory behaviors. [PDF]
Frontiers in Physiology, 2016 Vertebrates with laterally placed eyes typically exhibit preferential eye use for ecological activities such as scanning for predators or prey. Processing visual information predominately through the left or right visual field has been associated with ...

In situ predatory behavior ofMysis relicta in Lake Michigan [PDF]
Hydrobiologia, 1982 Selectivity coefficients (W′) and predation rates on Lake Michigan zooplankton were determined forMysis relicta during spring through fall using anin situ method. W′ values indicated the following ranked order of prey preference: Cladocera > copepod copepodites and copepod nauplii > adult diaptomids and cyclopoids.

Physical evidence of predatory behavior in Tyrannosaurus rex. [PDF]
Proc Natl Acad Sci U S A, 2013 Feeding strategies of the large theropod, Tyrannosaurus rex , either as a predator or a scavenger, have been a topic of debate previously compromised by lack of definitive physical evidence. Tooth drag and bone puncture marks have been documented on suggested prey items, but are often difficult to attribute to a ...

Behavioral Diversity of Predatory Arboreal Ants in Coffee Agroecosystems [PDF]
Environmental Entomology, 2008 Abstract 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

PLoS ONE, 2023 The reduction of predation is a potentially important factor for the evolution of the traits of an island animal species. By relaxed selection, insular animals tend to lose their antipredator behaviors.
