Low interbasin connectivity in a facultatively diadromous fish

Analysis of multielemental signatures in the otolith cores of diadromous fish revealed strong discrimination between river basins, suggesting that diadromeous fish spend their early lives within chemically distinct estuaries rather than the more homogenous marine environment, thus avoiding dispersal and maintaining genetic structure.

Format

The data frame 8,834 × 4 contains the following columns:

fish_code	integer	fish identifier
distance	numeric	distance from otolith core (um)
oto_sr8786	numeric	otolith strontium isotope (Sr87/Sr86) values
river	character	river of captured

Details

The datasets contains Strontium isotope ratio data for each individual fish. The authors use otolith chemistry to distinguish between diadromous and nondiadromous life histories and population genetics to examine interbasin connectivity resulting from diadromy. Otolith strontium isotope (87Sr/86Sr) transects identified three main life history patterns: amphidromy, freshwater residency and estuarine/marine residency.

Instrument: LA-ICP-MS (laser ablation-inductively coupled plasma mass spectrometry)
