Activity budgets and space use for two common Pacific parrotfish (Chlorurus Sp.) at Palmyra Atoll National Wildlife Refuge

Data was collected at Palmyra Atoll National Wildlife Refuge located
in the Central Pacific in 2014, and the work  focuses on two species
of Parrotfish, Chlorurus microrhinos and Chlorurus spilurus (formerly Cholrurus sordidus ). For C. microrhinos, the
project was designed to collect fine-scale spatial behavior data,
focusing on territory size, species interactions, and benthic impact
(i.e. feeding behavior). Focal follow data was collected by one or
two observer(s), either on snorkel or SCUBA, and recording focal
activity down to the second. Simultaneously, the observer would be
towing a GPS that was recording a location every 5 seconds and each
location was then associated with a particular behavior.  Throughout
this study individual fish were identifiable and successive follows
were possible on individuals. For C. spilurus the focus of the project was to collect behavioral time budget data
on feeding, territorial defense, and spawning behavior.  The ‘Chlorurus_Area_Palmyra_2014.csv’ data only covers C.
Microrhinos and gives the 95% KUD area estimation for GPS
towed tracks, as well as the 95% KUD area for locations where
feeding was occurring. We also report the step length between
successive points for the entire follow as well as where feeding was
occurring.   The ‘Chlorurus_Activity_Palmyra_2014.csv’ is for both C.
Microrhinos and C. spilurus and
reports the start and stop time of each focal follow as well as the
start and stop time of each activity.  Activity descriptions can be
found in the metadata and the total length and phase for each
individual in our study can be found in
‘Fish_Information_Chlorurus_Data_2014.csv.
