Phylogeny within the Chondracanthidae (Poecilostomatoida, Copepoda) [PDF]

Zoologica Scripta, 2003
The existing systematics of the Chondracanthidae is based predominantly on female characters and divides them into two subfamilies: Chondracanthinae and Lernentominae. Phylogenetic analyses using maximum parsimony were performed using 186 male and female characters. Different trees were generated when male and female characters were analysed separately.

Testing the usefulness of optical data for zooplankton long‐term monitoring: Taxonomic composition, abundance, biomass, and size spectra from ZooScan image analysis

Limnology and Oceanography: Methods, Volume 20, Issue 7, Page 428-450, July 2022., 2022
Abstract The pelagic ecosystem of the Arctic Ocean is threatened by severe changes such as the reduction in sea‐ice coverage and increased inflow of warmer Atlantic water. The latter is already altering the zooplankton community, highlighting the need for monitoring studies.

Dwarfs or giants? Sexual size dimorphism in Chondracanthidae (Copepoda, Poecilostomatoida) [PDF]

Crustaceana, 2005
Abstract in English: Sexual size dimorphism in the Chondracanthidae is very marked: whether it is a consequence of males being dwarfs or females becoming giants is investigated. Chondracanthid females are between two and 30 times larger than their conspecific males.

A molecular‐based identification resource for the arthropods of Finland

Molecular Ecology Resources, Volume 22, Issue 2, Page 803-822, February 2022., 2022
Abstract To associate specimens identified by molecular characters to other biological knowledge, we need reference sequences annotated by Linnaean taxonomy. In this study, we (1) report the creation of a comprehensive reference library of DNA barcodes for the arthropods of an entire country (Finland), (2) publish this library, and (3) deliver a new ...
