Predatory Pricing in a Oligopolistic Framework [PDF]
, 1999 In this paper we study the nature of predatory behavior in an oligopolistic framework. We use the long-purse story of financial vulnerability to demonstrate that predatory behavior is less likely to occur in an oligopoly than in a monopoly.

Who was the real sabertooth predator: Thylacosmilus or Thylacoleo?
The Anatomical Record, EarlyView.Abstract Sabertoothed mammalian predators, all now extinct, were almost exclusively feloid carnivorans (Eutheria, Placentalia): here a couple of extinct metatherian predators are considered in comparison with the placental sabertooths. Thylacosmilus (the “marsupial sabertooth”) and Thylacoleo (the “marsupial lion”) were both relatively large (puma ...

Carnivory in Adult Female Eumenid Wasps (Hymenoptera: Vespidae: Eumeninae) and Its Effect on Egg Production [PDF]
, 2017 Seventy captive adult female wasps of the eumenid genera Ancistrocerus and Euodynerus were observed to feed on multiple prey items. It was shown experimentally that E.

The Anatomical Record, EarlyView.Abstract The canine of saber‐toothed predators represents one of the most specialized dental structures known. Hypotheses about the function of hypertrophied canines range from display and conspecific interaction, soft food processing, to active prey acquisition.

The mechanistic basis of Myxococcus xanthus rippling behavior and its physiological role during predation. [PDF]
PLoS Computational Biology, 2012 Myxococcus xanthus cells self-organize into periodic bands of traveling waves, termed ripples, during multicellular fruiting body development and predation on other bacteria. To investigate the mechanistic basis of rippling behavior and its physiological

The Anatomical Record, EarlyView.Abstract Saber‐tooths, extinct apex predators with long and blade‐like upper canines, have appeared iteratively at least five times in the evolutionary history of vertebrates. Although saber‐tooths exhibit a relatively diverse range of morphologies, it is widely accepted that all killed their prey using the same predatory behavior. In this study, we CT‐

Scavenging by Jumping Spiders (Araneae: Salticidae) [PDF]
, 2017 Jumping spiders are usually considered obligate predators where ingestion is preceded by visual or tactile stimuli which elicit hunting behavior.
