Abstract With almost 2,600 species, Rodentia is the most diverse order of mammals. Here,
we provide an overview of changes in our understanding of the systematics of living rodents …

Species are the fundamental unit of analysis in biodiversity. They are often divided into
subspecies, or into 'evolutionarily significant units'(ESUs). The imprecise demarcation …

Mesoamerica is considered a biodiversity hot spot with levels of endemism and species
diversity likely underestimated. Unfortunately, the region continues to experience some of …

Many subspecies were described to capture phenotypic variation in wide-ranging taxa, with
some later being found to correspond to divergent genetic lineages. We investigate whether …

Assessing the true lineage diversity in elusive nocturnal organisms is particularly
challenging due to their subtle phenotypic variation in diagnostic traits. The cryptic small …

Conservation efforts rely on robust taxonomic assessments that should be based on critical
assessment of interspecific boundaries, infraspecific variation, and potentially distinctive …

Martes martes, commonly called the European pine marten, is a small predator widespread
in western Eurasia. In almost all its geographic distribution, it is autochthonous. It is as a …

The subspecies concept is one of the most controversial in Linnean taxonomy. In the past,
subspecies were described without a clear conceptual framework, triggering confusion and …

Although the mitochondrial diversity of Abrothrix olivacea has been widely studied, the
phylogeographic structure and the historical demography of this species are still not fully …

The seminal studies of Feth et al.(1964) and Garrels and Mackenzie (1967) describe the
chemical weathering processes controlling the geochemistry of spring waters in the Sierra …
