Local reflects global: Life-stage dependent changes in the phenology of coastal habitat use by North Sea herring

Climate warming is affecting the suitability and utilisation of coastal habitats by marine fishes around the world. Phenological changes are an important indicator of population responses to climate-induced changes but remain difficult to detect in marine fish populations. The design of large-scale monitoring surveys does not allow fine-grained temporal inference of population responses, while the responses of ecologically and economically important species groups such as small pelagic fish are particularly sensitive to temporal resolution. Here, we use the longest, highest-resolution time series of species composition and abundance of marine fishes in northern Europe to detect possible phenological shifts in the small pelagic North Sea herring. We detect a clear forward temporal shift in the phenology of nearshore habitat use by small juvenile North Sea herring. This forward shift can best be explained by changes in water temperatures in the North Sea. We find that reducing the tempora..., This data is part of the long-term NIOZ  kom-fyke monitoring program (https://www.nioz.nl/en/expertise/wadden-delta-research-centre/expertise-wadden/fish/kom-fyke-monitoring), , # Local reflects global: Life-stage dependent changes in the phenology of coastal habitat use by North Sea herring

This dataset contains the raw data and R-scripts used in the manuscript **Local reflects global: Life-stage dependent changes in the phenology of coastal habitat use by North Sea herring**.

## Description of the data and file structure

The dataset is composed of a raw **Data ** folder and an **R-code ** folder that can be used to run the analyses presented in the manuscript.

## Data folder

The **Data ** folder, contains four .csv files :

* *Daily_Jetty_Data.csv - containing the local Wadden Sea water temperature time series*
* *NS_temp_series.csv - containing the combined regional North Sea water temperature time series* 
* *The NS_temp folder contains .csv files with the separate years of the North Sea water temperature time series, and these*

*are brought together...
