Toward a global phylogeny of the "living fossil" crustacean order of the Notostraca. [PDF]

open access: yesPLoS ONE, 2012
Tadpole shrimp (Crustacea, Notostraca) are iconic inhabitants of temporary aquatic habitats worldwide. Often cited as prime examples of evolutionary stasis, surviving representatives closely resemble fossils older than 200 mya, suggestive of an ancient ...

Fauna of Anostraca, Notostraca and Conchostraca of the Kharkiv region

open access: yesVìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Bìologìâ, Ekologìâ, 2012
The species composition of the fauna of Anostraca, Notostraca and Conchostraca was studied in the Kharkiv region. Streptocephalus torvicornis (Waga, 1842) was found in the Kharkiv Region for the first time and Chirocephalus shadini (Smirnov, 1928) was ...

High lability of sexual system over 250 million years of evolution in morphologically conservative tadpole shrimps [PDF]

open access: yesBMC Evolutionary Biology, 2013
Background Sexual system is a key factor affecting the genetic diversity, population structure, genome structure and the evolutionary potential of species.

First complete mitochondrial genome from family Moinidae, Moina macrocopa (Straus, 1820) (Cladocera; Moinidae) [PDF]

open access: yesMitochondrial DNA. Part B. Resources, 2022
We sequenced and annotated the complete mitochondrial genome for the freshwater water flea Moina macrocopa (Straus, 1820). This is the first mitogenome for the family Moinidae. The complete mitogenome of M.

Exploring mitogenome evolution in Branchiopoda (Crustacea) lineages reveals gene order rearrangements in Cladocera [PDF]

open access: yesScientific Reports, 2022
The class Branchiopoda, whose origin dates back to Cambrian, includes ~ 1200 species which mainly occupy freshwater habitats. The phylogeny and systematics of the class have been debated for long time, until recent phylogenomic analyses allowed to better

The complete mitogenome of Leptestheria brevirostris Barnard, 1924, a rock pool clam shrimp (Branchiopoda: Spinicaudata) from Central District, Botswana [PDF]

open access: yesMitochondrial DNA. Part B. Resources, 2021
Spinicaudatan clam shrimp are a widespread and diverse group of branchiopod crustaceans, yet few mitochondrial genomes have been published for this taxonomic group.

A new calmanostracan crustacean species from the Cretaceous Yixian Formation and a simple approach for differentiating fossil tadpole shrimps and their relatives [PDF]

open access: yesZoological Letters, 2019
Background Calmanostraca is a group of branchiopod eucrustaceans, with Triops cancriformis and Lepidurus apus as most prominent representatives. Both are regularly addressed with the inaccurate tag “living fossil”, suggesting that the morphology has ...

Climate-related drivers of nutrient inputs and food web structure in shallow Arctic lake ecosystems [PDF]

open access: yesScientific Reports, 2022
In order to predict the effects of climate change on polar ecosystems, disentangling mechanisms of nutrient transfer in food webs is crucial. We investigated sources of nutrients in tundra lakes, tracing their transfer through the food web and relating ...

Multiple global radiations in tadpole shrimps challenge the concept of ‘living fossils’ [PDF]

open access: yesPeerJ, 2013
‘Living fossils’, a phrase first coined by Darwin, are defined as species with limited recent diversification and high morphological stasis over long periods of evolutionary time.

EVOLUTION IN THE NOTOSTRACA [PDF]

open access: yesEvolution; International Journal of Organic Evolution, 1955
The Notostraca are phyllopod Crustacea in which the carapace is shield-shaped and covers the anterior part of the body; together with other phyllopods, they are considered to be relatively unevolved Crustacea-there is a high, but irregular, number of appendages (forty to sixty pairs are usual) and the segmentation of the body is anameristic.
