Description

This dataset describe the distribution of two hyporheic crustacean taxa (Bogidiellidae, Amphipoda and Anthuridae, Isopoda) in streams of New Caledonia. We sampled the two taxa at 228 sites. At each site, we quantified nine local predictors related to habitat area and stability, sediment metabolism and water origin, and eight catchment predictors related to geology, area, primary productivity, land use and specific discharge.

Notes

This dataset allows to reproduce the statistical analysis whose results are presented in the article:
"Unique and shared effects of local and catchment predictors over distribution of hyporheic organisms: does the valley rule the stream? ", Mouron et al. 2022, Ecography (https://doi.org/10.1111/ecog.06099)

- "Mouron_et_al_2022_Landcover.csv" : Landcover data from GIS analysis to perform correspondence analysis (see script).
Variables : "Bare soil","Herbaceous","Shrubs","Mature forest","Urban","Water" ; i.e. the land cover composition for the 228 catchments (see Supplementary material Appendix 1, Fig. A1).

- "Mouron_et_al_2022_data.csv" : main dataset that contain occurences of Bogidiellids and Anthurids, local predictors and catchment predictors for 228 sites.

The 228 freshwater hyporheic sites are identified by a code ("Site_Code") and coordinates in WGS 84 ("X_long","Y_lat").

Occurences ("Bogi","Anthu") are presence/absence data for subterranean crustaceans Bogidiellidae and Anthuridae sampled in November 2016, November 2017 and July 2018. The nine local predictors describe in-stream habitat conditions : river width ("River_width", m), specific conductance("Sp_conductance", µS/cm), dissolved oxygen ("DO", mg/L), redox potential ("Redox_potential", mV), pH ("pH"), temperature of hyporheic water ("Temperature", °C), mean annual air temperature ("Mean_annual_temp", °C), elevation ("Elevation", m) and stream slope ("Stream_slope", m/m).

The eight catchments predictors describe the entire upstream contributing catchment : catchment area ("Catchment_area", km2), areal proportion of peridotite ("Peridotite", %), three land cover predictors ("Landcover1","Landcover2","Landcover3"), normalized difference vegetation index ("NDVI"), mean annual precipitation ("Precipitation", mm/year) and low flow specific discharge ("Discharge", L/s/km2).
