Lakshadweep Archipelago coral fish community reassembly

Share:

Description

A list with three datasets containing presence-absence data for the reassembly proccess of coral fish communities in three atolls (Agatti, Kadmat and Kavaratti) of the Lakshadweep Archipelago (India).

Format

A list with 3 dataframes, each corresponding to the survey of a different atoll. Dataframes have in columns:

Species

Name of the species found

Trophic.Level

A number indicating the trophic level of the surveyed species

Presence-absence data

Several columns with letters (indicating the atoll surveyed) and the year in which the surveys were done

Guild

Guild of the surveyed species

Details

Surveys were conducted from 2000 to 2011 in order to follow community reassembly after a coral mass mortality event in the relatively unfished Lakshadweep Archipelago. Results indicated that higher trophic groups suffer an increased extinction rate even without fishing targeting them.

Note

Kavaratti atoll was not surveyed in 2000 and 2010.
