Initiation and spread of escape waves within animal groups [PDF]
, 2015 The exceptional reactivity of animal collectives to predatory attacks is thought to be due to rapid, but local, transfer of information between group members. These groups turn together in unison and produce escape waves.

Variability of jaw muscles in Tunisian street dogs and adaptation to skull shape
The Anatomical Record, EarlyView.Abstract The impact of artificial selection on the masticatory apparatus of dogs has been poorly studied, and comparative data with dogs subjected to more natural constraints are lacking. This study explores the jaw musculature of Tunisian street dogs, which are largely free from the influence of breed‐specific selection.

Predatory behavior of Pseudodorus clavatus (Diptera, Syrphidae) on aphids tended by ants
, 2013 Predatory behavior of Pseudodorus clavatus (Diptera, Syrphidae) on aphids tended by ants. In this study, we examined the interactions between myrmecophilous aphids, their ant-guards and a predatory syrphid species, Pseudodorus clavatus (F.).

The Anatomical Record, EarlyView.Dental microwear texture analysis of Smilodon samples from Florida's Pleistocene reveals moderate carcass utilization (like modern African lions) across space and time, with more subtle dietary shifts in response to fluctuating climates. Abstract Smilodon, the iconic saber‐toothed cat, was a Pleistocene apex predator comprised of three morphologically ...

Holmes and the Bald Man: Why Rule of Reason Should Be the Standard in Sherman Act Section 2 Cases [PDF]
, 2006 [Excerpt] It has been argued that the antitrust laws’ legislative history supports the notion that the laws were meant to prohibit anticompetitive price cuts – regardless of whether they are below cost. Thus, predatory pricing claims used to turn simply

Sharpening our understanding of saber‐tooth biomechanics
The Anatomical Record, EarlyView.Abstract Saber‐teeth are a striking example of convergent evolution in vertebrate predators, having evolved multiple times in mammals and their early ancestors. While there is broad consensus that saber‐toothed taxa employed a distinct biting strategy compared to conical‐toothed carnivores, like the lion, the precise mechanics and variability of this ...

Commentary: What's so interesting about sabertooths?
The Anatomical Record, EarlyView.Abstract Sabertooth creatures are fascinating to the public and to scientists. This Special Issue on The Anatomy of Sabertooths starts with a discussion of what exactly a sabertooth is, continues with a couple of papers about other animals with extraordinarily long teeth, and then delves into analyses of fossil sabertoothed taxa—some of which are not ...
