Speciation is a fundamental evolutionary process, the knowledge of which is crucial for
understanding the origins of biodiversity. Genomic approaches are an increasingly important …

Background noise can interfere with the detection and discrimination of crucial signals
among members of a species. Here we investigate the vocal behaviour in the presence and …

The exploitation of non-invasive samples has been widely used in genetic monitoring of
terrestrial species. In aquatic ecosystems, non-invasive samples such as feces, shed hair or skin…

Killer whales (Orcinus orca) currently comprise a single, cosmopolitan species with a
diverse diet. However, studies over the last 30 yr have revealed populations of sympatric “ecotypes…

Organochlorine (OC) pesticides and the more persistent polychlorinated biphenyls (PCBs)
have well-established dose-dependent toxicities to birds, fish and mammals in experimental …

Marine mammals from different mammalian orders share several phenotypic traits adapted
to the aquatic environment and therefore represent a classic example of convergent evolution…

Analysing population genomic data from killer whale ecotypes, which we estimate have
globally radiated within less than 250,000 years, we show that genetic structuring including the …

Ecological divergence has a central role in speciation and is therefore an important source
of biodiversity. Studying the micro‐evolutionary processes of ecological diversification at its …

OBJECTIVE: To examine associations between serum macrophage migration inhibitory factor
(MIF) and disease-related variables and corticosteroid use in patients with systemic lupus …

Mitochondria produce up to 95 per cent of the eukaryotic cell's energy. The coding genes of
the mitochondrial DNA may therefore evolve under selection owing to metabolic …
