An estimated two billion people live in areas presently affected by fragility, armed conflict, and violence. In many of these locations armed non-state actors (e.g. rebel groups) rather than the state are the primary governors (Word Bank 2024). An estimated 66 million live under the direct rule of armed non-state actors (Breslawski in J Glob Secur Stud 7(1):ogab017 2022). With the growing severity of climate impacts, armed non...

To assess the correlation between four visual morphological types based on body colour and shape (fario trout, FT ; shiny fario, SFT ; presmolt trout, PST; typical smolt ST) of juvenile brown trout Salmo trutta during downstream spring migration and the biological form at the adult stage (river or sea), mark–recapture experiments were carried out over a period of 23 years. Evidence is provided that the visual SFT type is not a...

Using Pectinaria koreni as a biological model of larval dispersal, we coupled the analysis of differently evolving genetic markers (mitochondrial cytochrome oxidase I and four microsatellite loci) to hydrodynamic modeling of larval transport in the English Channel. To determine the influence of historical and contemporary processes on the genetic structure of our study populations, genetic relationships between English Channel...

The brittle‐star Acrocnida brachiata (Montagu) lives in sandy‐bottom habitat of both intertidal and subtidal zones along the coasts of the northwestern Europe. An allozyme frequency‐based survey (five enzyme loci) was combined with a mitochondrial (mt) COI haplotype analysis (598‐bp sequences) on 17 populations to trace back past colonization pathways from the actual population structure of the species. Both genetic markers di...

The historic processes which have led to the present‐day patterns of genetic structure in the marine coastal fauna of the Northeast Atlantic are still poorly understood. While tectonic uplifts and changes in sea level may have caused large‐scale vicariance, warmer conditions during glacial maxima may have allowed pockets of diversity to persist to a much wider extent than in the Northwestern Atlantic. The large‐scale geographi...
