Meanings of species group in English

We revise the Afrotropical Agabus raffrayi species group, motivated by the discovery of new diversity in Kenya and South Africa.

This represents the most taxonomically comprehensive genomic treatment of the spruce budworm species group, which is further supported by the broad agreement among multiple methodologies.

Mixed- species groups are commonly found in mammals and birds.

Their relationship with other species groups within the subgenus is assessed and their divergence times are estimated.

Decreases were evident in all of the major contributing species groups, with the exception of skunks and bats.

Plants can regularly be manipulated to breed across traditional species groups and a variety of organisms can share genetic material without breeding at all.

However, a correct determination by morphology is challenging in many species groups due to high morphological variability and polymorphisms within, but low variability between species.
