Behavioral assays provide powerful tools for understanding neuronal function. Here we present several protocols for quantifying predatory feeding behavior found in the model nematode Pristionchus pacificus and its relatives. Additionally, we provide methods for analyzing predatory feeding adaptations including mouth structures and teeth.

Cerebral perfusion is maintained across a range of pressures via cerebral autoregulation. However, characterizing autoregulation requires prominent pressure fluctuations at regulated frequencies. The described protocol will show how oscillatory lower body negative pressure can generate pressure fluctuations to provide data for projection pursuit regression for quantification of the autoregulatory curve.

Task Interruption and Resumption Paradigm for Testing the Activation and Pursuit of an Abstract Thinking Goal
0 Views •
2017
This protocol was designed to test the activation and pursuit of cognitive goals (e.g., an abstract thinking goal) using the task interruption and resumption paradigm. The protocol is suitable for cognitive goals that are automatically pursued once activated, as the distraction procedure prevents goal pursuit during the interruption period.

FAQs
The sensory cue available to a predator shapes how pursuit unfolds. Visual, chemical, and acoustic information can initiate tracking, while changes in the prey’s position provide feedback for altering speed and direction. This coupling of perception and movement allows the predator to respond dynamically rather than follow a fixed route.
Pursuit decisions reflect a balance among energy expenditure, risk, and expected reward. Continuing may increase the chance of capture, but it also commits resources while conditions change. Abandonment therefore represents an informative outcome, not simply failure: it can indicate that the anticipated benefit no longer justifies the costs or risks of continuing.
A prey’s escape maneuvers make pursuit a moving interaction rather than a one-sided approach. Changes in prey movement can require the predator to modify both direction and speed, linking locomotor performance with ongoing decisions. Examining these adjustments helps explain how animals respond to changing positions and why some encounters end before capture.
Capture, abandonment, and escape mark different endpoints with different behavioral implications. Capture indicates that the pursuit led to prey acquisition, whereas abandonment or escape shows that the interaction ended without capture. Comparing these outcomes helps investigators connect movement and sensory responses with the predator’s changing assessment of conditions.
Researchers can organize an encounter as a sequence beginning with cue detection, followed by tracking, movement adjustments, and an attempted capture. Analysis can then distinguish whether the interaction ended in capture, abandonment, or escape. This framework connects observable changes in speed and direction with decisions made under shifting environmental conditions.
Predatory pursuit provides a context for comparing locomotion, sensory systems, and hunting strategies across animals. Because the interaction links perception, movement, and decision-making, it also helps researchers examine predator-prey dynamics in changing environments. These comparisons place individual chase behavior within broader questions in behavioral ecology and animal behavior.
