Temporal trend data (2005-2020) in density and biomass of 13 herbivorous fishes in the Gulf of California.

This dataset comes from a multi-institution compilation of monitoring information for 13 marine herbivorous fishes belonging to six genera of five families: Acanthuridae, Girellidae, Kyphosidae, Pomacentridae and Scaridae, gathered from 2005 to 2020 in the Gulf of California. The database presents a total of 884 records of biomass and density got from 15,542 visual censuses performed using scuba diving in 34 localities comprising 268 rocky and coral reef sites. The censuses consisted of belt transects (250 m, 100 m, and 60 m) laid parallel to the coastline, where expert monitors recorded the abundance of all observed adult individuals of the 13 target herbivorous species, and visually estimated the total length (cm) of each fish.

An estimate of the number of white sharks Carcharodon carcharias interacting with ecotourism in Guadalupe Island.

The aim of the present study is to provide an estimate of the number of white sharks Carcharodon carcharias that seasonally interact with ecotourism boats in Guadalupe Island using Schnabel's mark-recapture method and 6316 records of white sharks during 2012-2014. The results of the estimation highlight an abundance of 78 white sharks 95% C.I.

Checklist and analysis of completeness of the reef fish fauna of the Revillagigedo Archipelago, Mexico.

This paper presents an updated checklist of cartilaginous and bony fishes from the Revillagigedo Archipelago reefs and nearby areas (Tropical Eastern Pacific). To compile this list, we gathered data from field surveys between 1994 and 2015, from an exhaustive literature review, and by consulting museum collections and databases. With these records we estimated the completeness of the local fish inventory using four non-parametric rarefaction methods.

Global human footprint on the linkage between biodiversity and ecosystem functioning in reef fishes.

Difficulties in scaling up theoretical and experimental results have raised controversy over the consequences of biodiversity loss for the functioning of natural ecosystems. Using a global survey of reef fish assemblages, we show that in contrast to previous theoretical and experimental studies, ecosystem functioning (as measured by standing biomass) scales in a non-saturating manner with biodiversity (as measured by species and functional richness) in this ecosystem. Our field study also shows a significant and negative interaction between human population density and biodiversity on ecosystem functioning (i.
