Phylogenetic Analysis of the Stomatopoda (Malacostraca) [PDF]

Journal of Crustacean Biology, 1997
ABSTRACT The stomatopods or mantis shrimps are malacostracan crustaceans of the subclass Hoplocarida. All extant hoplocarids belong to the order Stomatopoda and suborder Unipeltata. The Unipeltata comprises the extinct, stem-lineage sculdids, and the crown-group which includes the 19 extant families with more than 400 species.

Myogenesis of Malacostraca – the “egg-nauplius” concept revisited [PDF]

Frontiers in Zoology, 2013
Malacostracan evolutionary history has seen multiple transformations of ontogenetic mode. For example direct development in connection with extensive brood care and development involving planktotrophic nauplius larvae, as well as intermediate forms are found throughout this taxon.

Is DNA metabarcoding an option for formaldehyde‐preserved zooplankton time series?

Limnology and Oceanography: Methods, EarlyView.
Abstract The recovery of amplifiable DNA from formaldehyde‐fixed (FF) zooplankton samples has long been considered problematic, but advances in degraded‐DNA retrieval have renewed interest in FF samples. To access the information stored in long‐term zooplankton time series, we evaluated methods for extracting amplifiable DNA from community samples ...

Discovery and Fine‐Scale Mapping of Hadal Xenophyophore Habitat in the Nova Canton Trough, Central Pacific Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.

Transcriptomics Unveil Dsx1 as a Critical Regulator in Sexual Dimorphism of Crustaceans

Integrative Zoology, EarlyView.
Sexually dimorphic traits are involved in reproductive competition and are shaped by sex‐biased gene expression. This study identifies Dsx1 as a key male‐biased gene in Morinoia aosen and demonstrates through RNA interference that its disruption feminizes male‐specific T3 leg structures.

Same Same, but Different: A Glossary of Carcino‐Entomology as a Basis for an Improved Communication and for a Modern View of Carcinology Encompassing Entomology

Acta Zoologica, EarlyView.
ABSTRACT One core aspect of science is communication, both among researchers as well as with the public. For successful communication, it is crucial that the terminology used is clear to avoid misunderstandings. Especially when researchers working on different groups of organisms communicate, they often use different terms for similar morphological ...

Taxonomy of the spring dwelling amphipod Synurella ambulans (Crustacea: Crangonyctidae) in West Russia: with notes on its distribution and ecology [PDF]

, 2012
This study deals with taxonomic problems of the semi-subterranean crangonyctid amphipod Synurella ambulans (F. Müller, 1846), well-known from various freshwater habitats in Europe. The taxonomy of the species S. ambulans and the generic diagnosis for the

The malacostracan fauna of two Arctic fjords (west Spitsbergen): the diversity and distribution patterns of its pelagic and benthic components

Oceanologia, 2017
This study examines the performance of pelagic and benthic Malacostraca in two glacial fjords of west Spitsbergen: Kongsfjorden, strongly influenced by warm Atlantic waters, and Hornsund which, because of the strong impact of the cold Sørkapp Current ...

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

Cladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

The nauplius eye and frontal organs in Malacostraca (Crustacea).

, 1965
The nauplius eye and frontal organs in the Malacostraca have been investigated. The present work is a direct continuation of the author's investigation of the same organs in decapod malacostracans (Elofsson, 1963).
