Cladocera are the ecologically most important group within the Branchiopoda. They are unquestionably branchiopods but their evolutionary origin remains unclear. One favored explanation of their origin is that they evolved from a reproductive larva of a clam shrimp‐like ancestor. To reveal a transformation and identify (potential) changes in chronology (heterochrony), we investigated and compared the development of representatives of two clam shrimp taxa, one of the Spinicaudata (Leptestheria… Expand
Unraveling the origin of Cladocera by identifying heterochrony in the developmental sequences of Branchiopoda
IntroductionOne of the most interesting riddles within crustaceans is the origin of Cladocera (water fleas). Cladocerans are morphologically diverse and in terms of size and body segmentation differExpand
The development of the nervous system in Laevicaudata (Crustacea, Branchiopoda): insights into the evolution and homologies of branchiopod limbs and ‘frontal organs’
TLDR
It is suggested that the larval uniramous mandibular palp, found in the larvae of all ‘large’ branchiopods, is largely exopodal of nature and that the endopodite of the trunk limbs consists of only one distal endite-like segment and not of three as proposed by others. Expand
Nervous system development in the fairy shrimp Branchinella sp. (Crustacea: Branchiopoda: Anostraca): Insights into the development and evolution of the branchiopod brain and its sensory organs
TLDR
Evidence of a fourth nauplius eye nerve and decussating projecting neuron tract found in Branchinella sp. Expand
From swimming towards sessility in two metamorphoses – the drastic changes in structure and function of the nervous system of the bay barnacle Amphibalanus improvisus (Crustacea, Thecostraca, Cirripedia) during development
TLDR
Through the larval development of Amphibalanus improvisus, a structural and thus also functional increase of complexity in favor of the peripheral nervous system and the ventral nerve cord is observed. Expand
The Origin of Cladocera (Crustacea, Branchiopoda): A New Understanding of an Old Hypothesis
TLDR
Comparative analysis of the ontogeny of representatives of two sister taxa showed that the paedomorphic morphology of cladocerans was caused by the cessation of development of the somatic structures at early larval stages ofOntogeny. Expand
Cyclestheria hislopi (Crustacea: Branchiopoda): a group of morphologically cryptic species with origins in the Cretaceous.
TLDR
Today's circumtropic distribution of Cyclestheria may be best explained by a combination of Gondwana vicariance and later dispersal across Asia and Australia when the tectonic plates of the two continents drew closer in the early Miocene. Expand
Development of the nervous system in Cephalocarida (Crustacea): early neuronal differentiation and successive patterning
TLDR
It appears that the neuroanatomical differences between the adult thorax and the abdomen result from this developmental sequence stopping earlier in the abdomen than in the thorax, compared with all other crustaceans studied so far. Expand
Developmental and Functional Morphology of Eulimnadia braueriana Ishikawa, 1895 (Branchiopoda: Spinicaudata) Feeding Structures: Combination of Filtering and Scraping Feeding Mechanisms.
TLDR
Comparisons of molar and thoracopod morphology between coexisting branchiopod species show some similarities and differences in filtering and scraping feeding structures, implying potential foraging resource differentiation among species. Expand
The brain and the corresponding sense organs in calanoid copepods - Evidence of vestiges of compound eyes.
TLDR
It is suggested, on the basis of its position and the innervation it provides, that Gicklhorn's organ is homologous to the compound eye in arthropods and is a further feature supporting the homology of the nauplius eye in crustaceans. Expand
Embryonic neurogenesis in Pseudopallene sp. (Arthropoda, Pycnogonida) includes two subsequent phases with similarities to different arthropod groups
BackgroundStudies on early neurogenesis have had considerable impact on the discussion of the phylogenetic relationships of arthropods, having revealed striking similarities and differences betweenExpand

The nervous system of Leptodora kindtii (Branchiopoda, Cladocera) surveyed with confocal scanning microscopy (CLSM), including general remarks on the branchiopod neuromorphological ground pattern.
TLDR
Evidence that the ganglia of the maxillula and maxilla segments have not been incorporated in other ganglia, as suggested earlier is found, and the innervation of the 'lateral lobes' of the "lower lip' indicates a correspondence between these lobes and themaxillules. Expand
On the ontogeny of Leptodora kindtii (Crustacea, Branchiopoda, Cladocera), with notes on the phylogeny of the Cladocera
TLDR
This study describes the ontogeny of L. kindtii (Haplopoda), including general body proportions, appendages, the carapace, and other external structures in an attempt to facilitate the comparison of its aberrant morphology to that of other branchiopods. Expand
The formation of the nervous system during larval development in Triops cancriformis (Bosc) (crustacea, Branchiopoda): An immunohistochemical survey
TLDR
A correlation between neurotransmitter expression and locomotion is suggested and the development of thenervous system during the first five larval stages of Triops cancriformis is provided. Expand
External morphology of the male of Cyclestheria hislopi (Baird, 1859) (Crustacea, Branchiopoda, Spinicaudata), with a comparison of male claspers among the Conchostraca and Cladocera and its bearing on phylogeny of the ‘bivalved’ Branchiopoda
The adult male of Cyclestheria hislopi, sole member of the spinicaudate conchostracan clam shrimp family Cyclestheriidae and a species of potential phylogenetic importance, is described for the firstExpand
On the larval development of Eubranchipus grubii (Crustacea, Branchiopoda, Anostraca), with notes on the basal phylogeny of the Branchiopoda
TLDR
It is shown that the large, proximal endite of the trunk limbs in the adult Anostraca is actually a fusion product of two smaller endites which make their appearance in the early larval development, and seems most plausible to consider L. rhyniensis a stem lineage anostracan. Expand
Study of the late embryogenesis of Daphnia (Anomopoda, ‘Cladocera’, Branchiopoda) and a comparison of development in Anomopoda and Ctenopoda
TLDR
The embryonic development of Daphnia galeata and D. hyalina has been investigated by observing living embryos removed from female brood pouches and the sequence of morphological changes was analysed, as was the time at which the activity of certain organs began. Expand
An immunohistochemical study of structure and development of the nervous system in the brine shrimp Artemia salina Linnaeus, 1758 (Branchiopoda, Anostraca) with remarks on the evolution of the arthropod brain.
TLDR
The results indicate that the shape of the developing larval brain in A. salina closely resembles that in malacostracan embryos and the organization of the central complex as well as the tritocerebral innervation pattern of the labrum is homologous in this species and in Malacstraca. Expand
Comparative investigation of the late embryogenesis of Leptodora kindtii (Focke, 1844) (Crustacea: Branchiopoda), with notes on types of embryonic development and larvae in Cladocera
TLDR
A new scheme for the periodization of the embryogenesis of L. kindtii is proposed, which includes four well‐separated stages, which is similar in all these groups but the timing of shedding of the embryonic membranes differs. Expand

  • 2005
TLDR
A study on the larval (naupliar) development and the metamorphosis of Lynceus brachyurus, a member of the bivalved branchiopod order the Laevicaudata, and some specific features shared with the larvae of other “conchostracans” are identified. Expand

TLDR
The larval development of Caenestheriella gifuensis (Ishikawa, 1895), a Japanese spinicaudatan 'conchostracan', is described by scanning electron microscopy, and it is suggested that this ontogeny reflects the evolution of antennae in the con chostracans. Expand
