Functional morphology of the copulatory system of box crabs with long second gonopods (Calappidae, Eubrachyura, Decapoda, Crustacea)
This work investigates male and female copulatory organs in Calappula saussurei and Calappa pelii, two species of box crabs with second gonopods which are longer than the first pair, and proposes that long second Gonopods deliver male mating products directly into the dorsal chamber.
Morphology and function of the female reproductive system of Ebalia tumefacta (Decapoda, Brachyura, Leucosiidae)
The morphology and function of the female reproductive organs of Ebalia tumefacta were investigated using histological methods and revealed a new orientation of seminal receptacle compartments in Eubrachyuran crabs.
Ever more complex: a new type of organization of reproductive organs in female Dorippe sinica Chen, 1980 (Decapoda: Brachyura: Dorippidae).

Based on the genetic diversity shared between native and introduced range, Feiyunjiang, a tributary of the Yangtze River, emerges as a plausible source population for the original introduction of Chinese mitten crabs to Europe.
Coming and going – Historical distributions of the European oyster Ostrea edulis Linnaeus, 1758 and the introduced slipper limpet Crepidula fornicata Linnaeus, 1758 in the North Sea
This work combines the temporal and spatial information recorded with the collected specimens contained in several European natural history collections to recover the decline of O. edulis in the North Sea from the 19th century to the present and the process of invasion of C. fornicata.
A new type of brachyuran seminal receptacle in the masked crab Ethusa mascarone (Brachyura, Ethusidae)
The reproductive system of the female Ethusa mascarone was studied with a combination of histological and MRI‐techniques to reveal a completely new type of eubrachyuran seminal receptacle, which appears to be an apomorphic character of at least E. mascar one.
Comparative study of the morphology of the female seminal receptacles of Ilia nucleus and Persephona mediterranea (Decapoda, Brachyura, Leucosiidae).

The present study tested the value of natural history collections for reconstructing changes in the abundance and presence of species over time and concluded that they are an unmatched resource for recovering early species introductions and declines.
Phylogeography in an “oyster” shell provides first insights into the genetic structure of an extinct Ostrea edulis population

The historical phylogeography of Ostrea edulis was successfully depicted in its native range for the first time using ancient DNA methods on dry shells from museum collections and revealed a temporally stable population genetic pattern over the past 150 years despite large-scale translocations.
