Dams can landlock populations of amphidromous fishes that formerly migrated between rivers and seas. However, the genetic consequences of these life‐cycle changes remain unclear. Rhinogobius is a speciose genus of freshwater gobies widely distributed in Asia, including non‐migratory R. duospilus and facultatively amphidromous R. similis . Using genome‐wide SNPs from Hong Kong, southern China, we compared the genetic diversity...

Anthropogenic habitat transformation has led to population declines and increasing isolation of populations of many species, particularly top predators, where small and fragmented populations often experience limited dispersal and reduced genetic diversity. Jaguars ( Panthera onca ), for example, have lost half of their historical range and most populations outside the Amazon biome are small, isolated and highly threatened. He...

This paper presents a comprehensive analysis of the lithic assemblage from Level G1 of El Cierro Cave (northern Spain), attributed to the Cantabrian Lower Magdalenian. The study comprises 2,829 items, including 2,800 knapped artefacts, six macrolithic tools and 23 unmodified pebbles. Lithic procurement is dominated by flint, followed by quartzite and minor amounts of quartz. Eleven flint types have been identified, with local...
