Raman spectroscopic analysis of the composition of the clam-shrimp carapace (Branchiopoda: Laevicaudata, Spinicaudata, Cyclestherida): a dual calcium phosphate-calcium carbonate composition

open access: yesJournal of Crustacean Biology, 2020
Clam shrimps constitute a paraphyletic group of bivalved branchiopod crustaceans that includes orders Laevicaudata, Spinicaudata, and Cyclestherida. The unique mineral content of the carapace, formed by molt retention in Spinicaudata and Cyclestherida,

Risk reduction strategies in Branchipus schaefferi (Crustacea: Anostraca: Branchiopoda) as adaptation to a variable environment [PDF]

open access: yes, 2017
Mud from a temporary pool in Morocco was sequentially inundated and dried at the laboratory to follow the life history of Branchipus schaefferi. Once adult, each female was coupled to a male in order to study their life history and reproduction.

SEM morphological analysis of fertilized cysts in the genus Branchipus (Branchiopoda, Anostraca): Can cyst morphology be used as a reliable taxonomic criterion? [PDF]

open access: yesArchives of Biological Sciences, 2009
In order to illuminate taxonomic significance of cyst variability (as a part of total morphological variability) in the genus Branchipus, cysts (fertilized eggs) originating from southern parts of the Pannonian Plain are described on the basis of ...

Rediscovery of Branchipus schaefferi (Branchiopoda: Anostraca) in Belgium - notes on habitat requirements and conservation management

open access: yesBelgian Journal of Zoology
Fairy shrimps (Crustacea, Anostraca) are specialized inhabitants of inland water bodies that periodically dry or freeze over. Here we report the first observation since 1997 of a member of this basal crustacean order in Belgium and the first sighting of

Molecular phylogenetic analyses support the monophyly of Hexapoda and suggest the paraphyly of Entognatha [PDF]

open access: yes, 2013
BackgroundMolecular phylogenetic analyses have revealed that Hexapoda and Crustacea form a common clade (the Pancrustacea), which is now widely accepted among zoologists; however, the origin of Hexapoda remains unresolved.
