Bats3 | R Documentation |
The dataset describes the vocal activity of Noctule bats in autumn time in Eastern Ukraine. Not long ago, bats were migrating to the south to get food before hibernation, but now they stay where they were born for hibernation and become sedentary. The goal is to understand which environmental variables predict their level of activity (the column "calls" which contain a number of recorded calls which bats emit in flight at the site) and the probability of feeding (the column "buzz" represent 0 and 1 of presence/absence of specific feeding calls, which confirm feeding activity at the site). However, the data could be zero-inflated and yet the probability of buzz usually will be related to the presence of vocal activity first.
Bats3
A data frame with 70 rows and 21 variables:
the ID of recording site
the latitude
the longitude
the date of recording
the temperature in C
cloudiness in parts (max 1)
0 or 1 of rain (usually 0 as we won't expect bat activity during the rain)
categorical variable 0,1,2,3 where 0 absolute absence of artificial light and 3 full illumination
the time of recording
the number of recorded calls of Noctule bat
0 and 1 of feeding buzzes
the number of calls of another bat species Serotine bat
the number of calls of another bat species Kuhl's pipistrelle
the area of farmland
the area of vegetation coverage
the area of roads
the area of urban coverage
the area of water
the NDVI index mean for the plot
the standard deviation of NDVI index for plot
the number of hours since the first collection
Land type use categories are given in square meters within plots of 1 km radius around recording points.
