Description

During the summer of 2011, investigators examined the effects of lionfish predation on bridled goby populations through both a manipulative field experiment and a controlled lab experiment. This dataset includes results obtained from the controlled lab experiment. The lab experiments were conducted at the Lobster Lab at the Perry Institute for Marine Science on Lee Stocking Island, Bahamas.

Methods & Sampling

The investigators documented the gape refuge of bridled gobies accorss various sizes of lionfish. Bridled gobies, ranging in size from 1 to 6 cm total length, were offered to lionfish, ranging from 4 to 21 cm total length. The investigators recorded the time until detection by lionfish of goby, time to strike, strike sucess, and ingestion success. Each trial was 30 minutes, but some trials were allowed to go longer to see if the lionfish would ever eat the goby.

Data Processing Description

BCO-DMO Processing Notes:
- Modified parameter names to conform with BCO-DMO naming conventions.
- Added lat and lon for the site from the metadata provided.
- Replaced blanks with 'nd' ('no data').
- 09-Jan-2018: removed embargo on dataset.

Parameters

Date and time formats are described in python strftime() syntax.

Supplied Name	Supplied description	Supplied Units	Standard Name
ingestion_time_elapsed	The time point that the lionfish had the bridled goby completely in its mouth. If blank and success = 1, the goby was swallowed whole (the ingestion time = the time of strike).	H:MM:SS	time_elapsed
lat	Latitude of the site.	decimal degrees	lat
lon	Longitude of the site.	decimal degrees	lon
site	Name of the location where the experiments took place.	text	site
num_strikes	The number of strikes a lionfish took in each trial.	integer	no_bcodmo_term
strike_time_elapsed	The time point that the successful strike occured. If the time is 0:30:00, then the lionfish never attempted a strike. Each trial was 30 minutes, but some trials were allowed to go longer to see if the lionfish would ever eat the goby.	H:MM:SS	time_elapsed
detection_time_elapsed	The time point when a directed movement towards the bridled goby was observed. Each trial was 30 minutes total (0:30:00).	H:MM:SS	time_elapsed
goby_len_tot	The total length of the bridled goby in centimeters.	cm	fish_len
lionfish_len_tot	The total length of the lionfish in centimeters.	cm	fish_len
fish_id	Unique number for each lionfish in the experiment.	dimensionless	no_bcodmo_term
success	Whether or not the lionfish made a successful strike on the goby. 1 = succesful strike 0 = unsuccessful strike	1 or 0 (yes or no)	no_bcodmo_term
