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 specialized function of the left and right brain.

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 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 ...

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.

Predatory Luring Behavior of Odonates [PDF]
Journal of Insect Science, 2014 Organisms in the order Odonata are highly predatory insects that have a wide distribution globally. To date, there has been zero evidence that odonates employ luring as a means of prey acquisition. However, in this study, we show that Aeshna palmata larvae use abdominal movements to lure larval Argia vivida, subsequently consuming the lured organism ...

Rippling Is a Predatory Behavior in Myxococcus xanthus [PDF]
Journal of Bacteriology, 2006 ABSTRACT Cells of Myxococcus xanthus will, at times, organize their movement such that macroscopic traveling waves, termed ripples, are formed as groups of cells glide together on a solid surface. The reason for this behavior has long been a mystery, but we demonstrate here that rippling is a feeding ...

Predatory Behavior of Yellow Baboons [PDF]
Behaviour, 1976 Abstract1. A group of 32 yellow baboons (Papio cynocephalus) in the Masai-Amboseli National Park, Kenya, caught and ate 45 vertebrate prey items during 2519.19 hours of observation. 2. Eighty percent of the prey items were mammals and the most frequently eaten species were African hares (Lepus capensis), vervet monkeys (Cercopithecus aethiops) and ...

The predatory behavior of the Neotropical social wasp Polybia rejecta [PDF]
Behavioural Processes, 2017 We experimentally studied the predatory behavior of Polybia rejecta (Vespidae, Polistinae, Epiponini) towards 2-88 mm-long insects attracted to a UV light trap. Foragers, which began to hunt at 6:30, selected 4-14 mm-long prey insects. Prey detection by sight by hovering wasps was confirmed using decoys.

The identification of predatory behavior in the presence of uncertainty
International Journal of Industrial Organization, 1985 Abstract Out of the ongoing debate on what constitutes predatory behavior has surfaced the idea that it must entail a sacrifice of profits. The notion is that behavior which sacrifices profits must have an ulterior motive, namely an attempt to induce exit by rivals.
