Post-larval processes reduce the diversity of coral reef fish communities

Here we provide code and data for: Post-larval processes reduce the diversity of coral reef fish communities. The code and data provided can be used to generate the results included in both the main text and in the supplementary information. In our paper, we couple species-level community-wide abundance estimates for larval reef fishes with adult abundance data from intensive visual surveys and species-level traits to elucidate the factors that shape the diversity of adult coral reef fishes. We show that while larval supply is important in determining adult taxonomic and functional diversity, post-larval processes increase the numerical dominance of particular species, thus reducing overall diversity., Data collection:
Larvae: The sampling and identification procedures are described in detail in Kimmerling et al. 2018 and are reported here in brief. Larvae were collected between 2010-2011 either twice a month (July-November 2010) or monthly (December 2010-May 2011). Larvae were collected using a 1 m2 Multiple Opening and Closing Net and Environmental Sensing System (MOCNESS), mounted with 600 μm nets. The MOCNESS system was towed obliquely from a maximal depth of 180 m to the surface, at a speed of ~2 knots. Each net was opened for 5 minutes and then closed to sample larvae in the following depth strata: 180–140, 140–100, 100–75, 75–50, 50–25 and 25–0 m. These sampling transects ran parallel to the shoreline, over bottom depths of ~70, ~170, ~250 and ~500 m. Between 5-10 casts were made within each sampling day. Samples were instantly preserved on board in ethanol. In the laboratory, fish larvae were separated from the bulk zooplankton for subsequent morphological and molecular identi..., , # Post-larval processes reduce the diversity of coral reef fish communities

These data include species-level abundance estimates of larvae and adult coral reef fish, along with ecological and life-history traits. They are used to examine the relationship between larvae and adult diversity and how adult diversity is maintained.

## General description:

## Description of the data and files structure

The data is composed of several files as the data structure needed for analyses is different and several subsets are required.

The file `Data_table.xlsx` includes species abundances of larvae and adults of different data subsets and species traits, and should be considered as the 'Supporting Data' file associated with the publication. It includes a README tab. A CSV version is also available.

The files `Adult_community_matrix_-_multiplicative_non-corrected.csv` and `Adults_community_matrix_multiplicative_corrected.csv` are community matrix of adults, containing multiplicative, non-correct...
