Geographic destiny trumps taxonomy in the Roundtail Chub, Gila robusta species complex (Teleostei, Leuciscidae).

The Gila robusta species complex in the lower reaches of the Colorado River includes three nominal and contested species (G. robusta, G. intermedia, and G.

Experience with a Continuous Education Program for Clinical, Regulatory and Quality Affairs in Northwestern Switzerland.

The European Medical Device and In-Vitro Diagnostic Medical Device industry is currently facing a highly challenging situation, as applied regulations have changed significantly over the last year. To cope with this, a novel continuing education program for employees from these sectors provides knowledge and hands-on experience in clinical, regulatory and quality affairs. Since 2020 two classes have been successfully completed at the University of Applied Sciences and Arts Northwestern Switzerland: this paper describes the concept and content, the students, and the benefits both for participants and their employers.

Genome-wide analyses of the Bemisia tabaci species complex reveal contrasting patterns of admixture and complex demographic histories.

Once considered a single species, the whitefly, Bemisia tabaci, is a complex of numerous morphologically indistinguishable species. Within the last three decades, two of its members (MED and MEAM1) have become some of the world's most damaging agricultural pests invading countries across Europe, Africa, Asia and the Americas and affecting a vast range of agriculturally important food and fiber crops through both feeding-related damage and the transmission of numerous plant viruses. For some time now, researchers have relied on a single mitochondrial gene and/or a handful of nuclear markers to study this species complex.

A southern African origin and cryptic structure in the highly mobile plains zebra.

The plains zebra (Equus quagga) is an ecologically important species of the African savannah. It is also one of the most numerous and widely distributed ungulates, and six subspecies have been described based on morphological variation. However, the within-species evolutionary processes have been difficult to resolve due to its high mobility and a lack of consensus regarding the population structure.
