Osteopilus marianae
Catadupa Calling Vigor Index (CVI)
Patterns of North, Central & South Distributions
Passive acoustic "frog logger" nocturnal surveys:
North = 20 survey points
Central = 13 survey points
South = 6 survey points
Analyses of recordings commenced 15 minutes after sunset.
The first 180 minutes were divided into discrete 5-minute intervals.
"Presence detected" was scored for each interval as a binomial "yes" or "no",
for a maximum CVI score of 36.
Mapped points show the average CVI of each geographic region,
for recordings collected in July 2014.
