Genetic diversity and connectivity of southern right whales (Eubalaena australis) found in the Brazil and Chile–Peru wintering grounds and the South Georgia (Islas Georgias del Sur) feeding ground
<p></p><p>As species recover from exploitation, continued assessments of connectivity and population structure are warranted to provide information for conservation and management. This is particularly true in species with high dispersal capacity, such as migratory whales, where patterns of connectivity could change rapidly. Here we build on a previous long-term, large-scale collaboration on southern right whales (Eubalaena australis) to combine new (nnew) and published (npub) mitochondrial (mtDNA) and microsatellite genetic data from all major wintering grounds and, uniquely, the South Georgia (Islas Georgias del Sur: SG) feeding grounds. Specifically, we include data from Argentina (npub mtDNA/microsatellite = 208/46), Brazil (nnew mtDNA/microsatellite = 50/50), South Africa (nnew mtDNA/microsatellite = 66/77, npub mtDNA/microsatellite = 350/47), Chile–Peru (nnew mtDNA/microsatellite = 1/1), the Indo-Pacific (npub mtDNA/microsatellite = 769/126), and SG (npub mtDNA/microsatellite = 8/0, nnew mtDNA/microsatellite = 3/11) to investigate the position of previously unstudied habitats in the migratory network: Brazil, SG, and Chile–Peru. These new genetic data show connectivity between Brazil and Argentina, exemplified by weak genetic differentiation and the movement of 1 genetically identified individual between the South American grounds. The single sample from Chile–Peru had an mtDNA haplotype previously only observed in the Indo-Pacific and had a nuclear genotype that appeared admixed between the Indo-Pacific and South Atlantic, based on genetic clustering and assignment algorithms. The SG samples were clearly South Atlantic and were more similar to the South American than the South African wintering grounds. This study highlights how international collaborations are critical to provide context for emerging or recovering regions, like the SG feeding ground, as well as those that remain critically endangered, such as Chile–Peru.</p><p></p>

Galaxias maculatus occurrence data in marine and freshwater environments in rivers of southern Chile
<p>In the present study, we assessed ecological and historical factors (Gondwanan vicariance, marine dispersion) and potential dispersion (niche-tracking) that explain distribution of <em>Galaxias maculatus</em> in the Southern Hemisphere based on occurrences available in the Global Biodiversity Information Facility (GBIF; period 1980 to 2022) and ichthyological sampling in five river systems in southern Chile between March and November 2019. Ocurrence data extracted from GBIF are available at <a href="http://www.gbif.org">http://www.gbif.org</a> and additional ichthyological sampling data that were used are provided here. Data provided here are based on sampling of <em>Galaxias maculatus</em> at 12 sites in five river systems in southern Chile during March, May, August, and November 2019. Sampling sites were selected to cover a continuous river gradient, including (whenever possible) the lower, middle, and upper sections of each river system. Fish were captured using beach seines (5 m long, 1.5 m high, and 10 mm stretched mesh) in shoreline habitats of each evaluated river system.</p>
