Population structure and connectivity among coastal and freshwater Kelp Gull (Larus dominicanus) populations from Patagonia

The genetic identification of significant evolutionary units and information on their connectivity can be used to design effective management and conservation plans. Despite having high dispersal capacity, several seabird species show population structure due to both abiotic and biotic barriers to gene flow. The Kelp Gull is the most abundant species of gull in the southern hemisphere. In Argentina it reproduces in both marine and freshwater environments, with more than 100,000 pairs following a metapopulation dynamic across 140 colonies in the Atlantic coast of Patagonia. However, little is known about the demography and connectivity of inland populations. We aim to provide information on the connectivity of the largest freshwater colonies (those from Nahuel Huapi Lake) with the closest Pacific and Atlantic populations to evaluate if these freshwater colonies are being subsidized by the larger coastal populations. We sampled three geographic regions (Nahuel Huapi Lake and the Atlantic ..., These are ddRAD data generated following this paper.

## There are a total of 133 files in the folder. These belong to a ddRAD assembly generated with the software Stacks version 2.3e. The files can be devided in the categories shown below.

## Aligned Sequences

There are 117 files derived from sequences from different individuals (one file per individual) aligned to the Herring Gull reference genome (`GCA_013400295.1_ASM1340029v1_genomic.fna`) as indicated in the paper. Each file is named with a number and a series of letters. The letters indicate both the species (starting wit GC for the common Spanish name of the study species, \"Gaviota Cocinera\") and the geographic origin of the sample. The geographic origin is indicated first with letters denoting the specific locality and subsequently with the general region as follows:

Pacific coast (CP)

* Maiquillahue (VA)
* Isla Conejo (IC)
* Puñihuil (PU)

Nahuel Huapi Lake (LNH)

* Islets Gaviotero 1 and Gaviotero 2 (G1, G2)
