What explains the trot-gallop transition in small mammals?
The transition from trot to gallop in quadruped mammals has been widely hypothesized to be a strategy to minimize the energetic costs of running. This view, however, has been challenged by some experimental evidence suggesting instead that this transition might be triggered by mechanical cues, and would occur when musculoskeletal stresses reach a certain critical value. All previous experiments...
متن کاملBiomechanical determinants of transverse and rotary gallop in cursorial mammals.
Transverse and rotary gallop differ in the placement of the leading hindfeet and forefeet: ipsilateral in the former gait, contralateral in the latter. We analysed 351 filmed sequences to assess the gallop type of 89 investigated mammalian species belonging to Carnivora, Artiodactyla and Perissodactyla orders. Twenty-three biometrical, ecological and physiological parameters were collected for ...
متن کاملWhy don't male mammals lactate?
Why has male lactation never evolved? This question is discussed with attention to (a) the physiological and ontogenetic modifications that such an evolutionary development would require, and (b) the reproductive strategies of monogamous mammals and the costs and benefits of extant forms of parental investment. Functional male lactation would require changes in sexually differentiated ontogenet...
متن کاملWhy Elephants Gallop: Assessing and Predicting Organizational Performance in Federal Agencies
'In a recent article published in this journal, the authors argued that elephants and public organizations have something in common. Both are saddled with inaccurate stereotypes. Elephants are believed to be slow and insensitive creatures, when in fact they can run very fast and are very sensitive. Similarly, public organizations are believed to be low-performing and unresponsive, when in fact ...
متن کاملA narrow QRS gallop rhythm
The QRS complexes 1, 2, 4, 5 and 7 are not preceded by atrial activation. The QRS morphology is slightly different from an A-V conducted beat (QRS 3, 6). Therefore an origin in the bundle branch system is presumed for beats 1, 2, 4, 5 and 7. An escape beat (QRS 2, 5) is retrogradely conducted to the atrium with atrial activation followed by AV conduction and ventricular capture (#3, 6). This ph...
