Phylogenetic systematics of the reptantian Decapoda (Crustacea, Malacostraca)
TLDR
It is shown that the Reptantia represent a monophyletic taxon, and alternative hypotheses of reptantian interrelationships, the systematic position of the Reptants within the decapods, and some conclusions concerning the habits and appearance of the reptilesantian stem species are discussed.
The evolution of arthropod heads: reconciling morphological, developmental and palaeontological evidence
TLDR
Current hypotheses about head segmentation and the nature of head structures from various perspectives are reviewed, and the concept of “primary” and “secondary antennae” in Recent and fossil arthropods are developed, it is proposed that Trilobita are stem lineage representatives of the Mandibulata.
The enigmatic Marmorkrebs (marbled crayfish) is the parthenogenetic form of Procambarus fallax (Hagen, 1870)
TLDR
It is suggested that the Marmorkrebs is the parthenogenetic form of P. fallax, a species found natively throughout peninsular Florida, USA, which has potential evolutionary and ecological implications at several levels.
The Articulata hypothesis – or what is a segment?
TLDR
Based on numerous similarities not shared with other bilaterian taxa it is suggested that segmentation of annelids and arthropods is homologous and apomorphic for a monophyletic Articulata.
Invertebrate neurophylogeny: suggested terms and definitions for a neuroanatomical glossary
TLDR
The use of revised neuroanatomical terminology in any new descriptions of the anatomy of invertebrate nervous systems will improve the comparability of this organ system and its substructures between the various taxa, and finally even lead to better and more robust homology hypotheses.
Evolution of the nauplius stage in malacostracan crustaceans
TLDR
From their distribution within the phylogenetic tree and from their larval characteristics, it is concluded that the free-living nauplius larvae of euphausiids and dendrobranchiate decapods are secondarily evolved from ontogenies without a free- living nAUplius.
Parthenogenesis in an outsider crayfish
TLDR
By virtue of its parthenogenetic reproduction, the marbled crayfish emerges not only as an interesting laboratory model but also as a potential ecological threat in that it could outcompete native forms should even a single specimen be released into European rivers.
Cell lineage studies in the crayfish Cherax destructor (Crustacea, Decapoda) : germ band formation, segmentation, and early neurogenesis

    Roux's archives of developmental biology
  • 1 December 1992
TLDR
The cell division pattern of the germ band of Cherax destructor is described from gastrulation to segmentation, limb bud formation, and early neurogenesis, compared with the early development of other crustaceans and insects.
