... was removed because of a skin injury during baseline tracking, including one female who was untagged for ∼3 weeks after an initial 3 weeks of tagging to recover from abrasions from the waistband, and was then retagged and tracked again. The location of each individual was recorded over at least 7 days...

... greater than 1, then the animals are rapidly returning to fixed tracks, if it is much less than 1, then they are following different but similarly orientated tracks as the move (as illustrated in Fig. 1 C). We note that this ratio is only capable of capturing the global strategy for isolated tracks...

... Arduino Behavior Bio-logging Physiological monitoring Tracking Animals continuously integrate their internal states and external environments to decide where, when and how to move through a landscape in search of food, shelter or a mate ( Nathan et al., 2008 ). Historically, researchers have...

...Sean Copley; Kalyanasundaram Parthasarathy; Mark A. Willis ABSTRACT While tracking odor plumes, male hawkmoths use optic flow cues to stabilize their flight movements with respect to their environment. We studied the responses of freely flying moths tracking odor plumes in a laboratory wind tunnel...

...Michael J. Moore; Alexandre N. Zerbini ABSTRACT Whale tracking tags often penetrate semi-rigid blubber, with intramuscular sharp tips and toggling barbs under the subdermal sheath to reduce premature shedding. Tag sites can show persistent regional swellings or depressions. Fibroelastic blubber...

... distortion, and the fact that camera gimbals do not typically contain encoders to give orientation relative to the platform. Care must be taken to avoid the UAS causing stress to the animals being tracked, which could affect behaviour ( Vas et al., 2015 ). One of the most exciting applications...

... discovered coming from laboratory studies or model systems. The miniaturisation of tracking technology in recent years now promises opportunities for studying navigation during migration itself (migratory navigation) on an unprecedented scale. Even if migration tracking studies are principally being designed...

... neurobiology is that measuring body kinematics during behavior is labor intensive and subjective. In order to quantify flight kinematics during different types of maneuvers, we have developed a visual tracking system that estimates the posture of the fly from multiple calibrated cameras. An accurate geometric...

... in swimming during all stages of development, we have developed a visual tracking system that estimates the posture of fish. Our current approach assumes planar motion of the fish, given image sequences taken from a top view. An accurate geometric fish model is automatically designed and fit to the images...

... of area-restricted searching (ARS) at various scales. Here, we present a new method, the fractal landscape method, which describes the peaks and valleys of fractal dimension along the animal path. We describe and test the method on simulated tracks, and quantify the effect of track inaccuracies. We show...

Lovespot photoreceptors respond more strongly than female photoreceptors to targets tracked during pursuit, with amplitudes...
