Description

Behavioral observations of lionfish, with a focus on hunting activity throughout the day, at native Pacific (Guam and the Philippines) vs. invasive Atlantic locations (Bahamas and Caymans) to assess possible differences between ranges. Particular emphasis was placed on species hunted, time spent hunting and total numbers of kills and strikes. The investigators hypothesized that lionfish at invaded locations would have higher success at killing prey and spend less time hunting.

Methods & Sampling

Dataset acquisition description

This sub-project aimed to compare native vs. invasive populations of lionfish, in order to assess some of the potential factors responsible for the invasive success of lionfish in the Atlantic. Assessment in the native range included analysis of behaviour and juvenile growth patterns, at two general locations: Guam and the Philippines. Behaviour was assessed via 10-minute observations on inividual lionfish, aiming to assess different individuals and their hunting behaviour as well as interactions with other species at different times of the day. Observations were done wherever lionfish were found, and included artificial habitats, coral reefs, sandy areas and reef channels with rock/boulder habitat. Observations in the native range were then compared to those at invaded locations (Bahamas and Caymans) undertaken with identical methods by other members of the team. Data were QA/QCd by spot checking against original field data sheets.

Loc_Note_11 = At boulder;non-coral;next to Prus cleaning colony;another PTVO under it in silt

-----------------------
Notes in body_orientation column:
Body_Note_1 = Upright and exposed but upon approach kept running away and tucking itself more and more until ended up in cave with only pectorals and tail seen
Body_Note_2 = Area w sm colonies of Pocillopora & recruit Chromis;vertcl position;under boat canopy;recently fallen;couldnt find lttle guy;kept envrnmnt dark & kept opening&closing space
Body_Note_3 = On top of massive boulder w somewhat live coral;horizntl position;next to darker phase volitans almost touching each other
Body_Note_4 = Under sm ledge near bottm facing wall vertically;diff place than othr times;but same head
Body_Note_5 = Upright on sandy bottom; under boulder; could be seen through a hole; right next to previous one

Data Processing Description

Dataset Processing Description

BCO-DMO Processing Notes:
- Changed parameter names to conform with BCO-DMO naming conventions.
- Removed apostrophes in the 'site' column. Replaced commas with semi-colons in the columns containing text.
- Added lat and lon for each site from the metadata sheet.
- Replaced blanks with 'nd' to indicate 'no data'.
- Replaced 'ICON' with 'ICON_reef' for consistency throughout dataset.
- Extracted very long notes/comments to improve visual display of the data in the browser.
- Edited notes/comments slightly to shorten length of fields.
- 27-Dec-2017: Removed embargo on dataset.
