Last Saturday was the US premiere of Dynasties, which documents lots of the same hypnotic trajectories of animal lives, lifted to a pseudo-Shakespearean height by the narration of Attenborough, whose voice, even at 92, still has a cadence that sounds both mournful and astonished, as if he pulled open the refrigerator, and there it was, a growling lion cub, how did you get in here, my boy?
An increasingly popular approach to study the role of selection for camouflage for evolutionary trajectories of animal colour patterns is to present images of prey on paper or computer screens to human 'predators'predators
There are several obstacles along the way including, as in The Overlanders, the inconvenient existence of a cliff coupled with the inconvenient trajectory of animals headed straight for it.
Recent evidence suggests that thermal attraction is gated by the presence of CO2 [6], although this conclusion was based experiments in which the actual flight trajectories of the animals were unknown and visual cues were not studied.
I will also study trajectories and speed of animals in order to assess whether they use more cognitive processes.
However, the pre-diapause phase can reveal important insights into the regulation and physiological trajectory of diapausing animals [ 19- 21].
To test whether distance traversed along the mean trajectory is predictive of animals' perceptual report, we separated the distribution of pooled projections for each stimulus into 3 bins.
We recorded and analyzed one hour-long trajectories of these fasted animals on bacteria.
During the free exploration of spatial environments, individual hippocampal neurons fire at specific spatial locations of the animal and are activated sequentially along the trajectory of the animal (place cells) (O'Keefe and Dostrovsky, 1971; O'Keefe and Nadel, 1978; McNaughton et al., 1983; O'Keefe and Recce, 1993; Wilson and McNaughton, 1993; Lee and Wilson, 2002).
In this paper, we present a new class of object of the R software, the class "ltraj" included in the package adehabitat, allowing the analysis of animals' trajectories.
