Synthesis of Population Trends Reveals Seascape-Wide Reorganisation of Biodiversity From Microalgae to Birds. [PDF]

Glob Chang Biol
We present a systematic and quantitative analysis of population trends to capture the seascape‐wide reorganisation of biodiversity from microalgae to birds. First, we categorised population trends and found over one third of populations in the Wadden Sea to change, that is, increase or decrease.

Molecular evidence for high frequency of multiple paternity in a freshwater shrimp species Caridina ensifera. [PDF]

PLoS ONE, 2010
Molecular genetic analyses of parentage provide insights into mating systems. Although there are 22,000 members in Malacostraca, not much has been known about mating systems in Malacostraca.

Uropods of Eumalacostraca (Crustacea s.l.: Malacostraca) and their phylogenetic significance [PDF]

Arthropod Systematics & Phylogeny, 2012
The uropods are the specialised sixth pair of pleopods of eumalacostracan Crustacea. Their quite variable morphology is suggestive of a good potential as a phylogenetic signal. Because uropods have hitherto been neglected in analyses of malacostracan phylogeny, we examined them in 11 representative species of Eumalacostraca and the sixth pleopods of a ...

THE FAMILY OLIBRINIDAE IN ITALY (MALACOSTRACA ISOPODA ONISCIDEA)

Redia, 2022
Taiti S., Gardini P. – The family Olibrinidae in Italy (Malacostraca Isopoda Oniscidea). Among the Oniscidea, the family Olibrinidae is still poorly known and was not yet recorded from Italy. The genus Castellanethes Brian, 1952, previously included in the family Trichoniscidae, is transferred to the family Olibrinidae, representing the first record of

Naupliar and Metanaupliar Development of Thysanoessa raschii (Malacostraca, Euphausiacea) from Godthåbsfjord, Greenland, with a Reinstatement of the Ancestral Status of the Free-Living Nauplius in Malacostracan Evolution. [PDF]

PLoS ONE, 2015
The presence of a characteristic crustacean larval type, the nauplius, in many crustacean taxa has often been considered one of the few uniting characters of the Crustacea.

The largest ghost shrimps ever: evidence from the fossil record and implications for the maximum size estimate of callianassoid burrowing ghost shrimps [PDF]

Acta Palaeontologica Polonica
Callianassoid burrowing ghost shrimps are mostly small animals, with a total length (from the tip of the rostrum to the end of the tailfan) typically not exceeding a few centimetres.
