In the last 15 years, 30 Hz has also become a feasible capture rate when a more "film like" look is desired, but ordinary video cameras are used.
At the receiving end, a digital display is free to independently present the image sequence at a multiple of its capture rate, thus reducing visible flicker.
For these displays, the 24-30 Hz material is usually displayed at 2x, 3x, or 4x the capture rate.
As with insectivores, frugivores showed significant declines in capture rates after isolation and four species showed effects of time since isolation.
In all analyses, the researchers controlled for the amphibian density by using capture rates as proxies for population density.
Merbach counted up to 22 individuals per minute falling into the pitchers and noted that the capture rate could easily exceed this for denser columns.
The new coastal charts helped the Union Navy increased its capture rate from one in ten blockade runners in 1861 to one in three by 1864.
Though the county shares the list with the police in other jurisdictions, the capture rate has not been overwhelming.
A high efficiency MERV 14 filter has a capture rate of at least 75% for particles between 0.3 to 1.0 micrometers.
