Predicting time-at-depth weighted biodiversity patterns for sharks of the North Pacific

Depth is a fundamental and universal driver of ocean biogeography, but it is unclear how the biodiversity patterns of larger, more mobile organisms change as a function of depth. Here, we developed a predictive biogeography model to explore how information of mobile species’ depth preferences influence biodiversity patterns. We employed a literature review to collate shark biotelemetry studies and used open-access tools to extract 283 total records from 119 studies of 1,133 sharks from 35 species. We then matched field guide reported depth ranges and IUCN habitat associations for each shark species to use as covariates in a hurdle variant of Ensemble Random Forests. We successfully fit this model (R2 = 0.63) to the noisy time-at-depth observations and used it to predict the time budgets of the Northeast Pacific shark regional pool (n = 52). We then assessed how occurrence diversity patterns, informed by minimum and maximum depth of occurrence, compared to time-at-depth weighted diversit..., , , # Predicting Time-at-Depth Weighted Biodiversity Patterns for Sharks of the North Pacific

This dataset contains all the collected species-specific summarizations, processed .RData files, and R scripts to produce the manuscript results.

## Description of the data and file structure

The datasets are structured into two separate types: (1) raw data contained in the \"Data\" folder in the Datafiles.zip and (2) processed data that are generated as outputs of the R scripts in the \"RData\" folder in the Scripts&Rdata.zip.

#### Species-specific time-at-depth raw data

In the \"Data\" folder is a \"Species-specific\" folder containing subfolders for each sharks species with a summarization of their time at depth included in the manuscript. Each subfolder has an Excel workbook with separate summarizations in each sheet. The sheet naming convention indicates which summarization is presented. Each summarization has...
