Ordered progression of nematogenesis from stem cells through differentiation stages in the tentacle bulb of Clytia hemisphaerica (Hydrozoa, Cnidaria).
TLDR
It is found that nematogenesis proceeds more rapidly in Clytia than in Hydra, and the tentacle bulb nematogenic ectoderm (TBE) was found to be polarized, with a clear progression of successive nematoblast stages from a proximal zone (comprising a majority of undifferentiated cells) to the distal end where the Tentacle starts.

Posterior patterning genes and the identification of a unique body region in the brine shrimp Artemia franciscana
TLDR
It is argued that the post-genital segments of Artemia constitute a unique body region that bears no obvious homology to previously characterised domains of Hox gene activity, and may play a role in the generation of body segments in insects. Expand
Revision of the Extant Genera of Limnadiidae (Branchiopoda: Spinicaudata)
TLDR
Both molecular and morphological data strongly support eight genera of the spinicaudatan clam shrimp family Limnadiidae, two of which are new to science and one (Paralimnadia) that is resurrected. Expand
Horizontal gene transfer and the evolution of cnidarian stinging cells
TLDR
Evidence is provided that a subunit of bacterial poly-γ-glutamate (PGA) synthase was transferred to an animal ancestor by HGT, suggesting that this gene acquisition had important consequences on the evolution of the stinging cells that cnidarians essentially use to capture prey. Expand
Knockdown of spalt function by RNAi causes de-repression of Hox genes and homeotic transformations in the crustacean Artemia franciscana.
TLDR
Using RNA interference (RNAi), it is shown that knocking down the expression of spalt has pleiotropic effects, which include thoracic to genital (T-->G), genital to thorACic (G-->T) and post-genital toThoracic (PG -->T) homeotic transformations. Expand
Revision of the egg morphology of Eulimnadia (Crustacea, Branchiopoda, Spinicaudata)
TLDR
Advice on museum collection management, a synthesis of the knowledge on egg morphology and an identification key of described Eulimnadia eggs is presented in order to prepare a general revision of this genus based on the egg morphology, which provides informative specific characters. Expand
Mitochondrial gene trees support persistence of cold tolerant fairy shrimp throughout the Pleistocene glaciations in both southern and more northerly refugia
TLDR
A phylogeography of the species Chirocephalus diaphanus Prévost, 1803 is reconstructed using partial sequences of the mitochondrial COI gene and the importance of different Pleistocene refugia to explain current diversity patterns is discussed. Expand
Molecular phylogeny of the Notostraca.
TLDR
The results confirm the monophyly of both extant notostracan genera Triops and Lepidurus with good support in model based and maximum parsimony analyses and form a biogeographic hypothesis that explains distributions of extant lineages predominantly by overland dispersal routes. Expand
The oldest notostracan (Upper Devonian Strud locality, Belgium)
A new notostracan crustacean, Strudops goldenbergi gen. et sp. nov., is described from the well-preserved terrestrial arthropod fauna of the Upper Devonian of Strud, Belgium. The fossil notostracanExpand
The neotropical genus Dendrocephalus (Crustacea: Anostraca: Thamnocephalidae) in Brazil (South America), with a description of two new species
TLDR
Two new species in the neotropical genus Dendrocephalus (Anostraca, Thamnocephalidae) are described from Brazil, with a detailed study of the frontal appendage, and of the endopodites of the first four thoracopods. Expand
