Organization and micromorphology of the ovo-spermathecal apparatus in earthworm Eudrilus eugeniae (Crassiclitellata, Eudrilidae) with a particular emphasis on the ovary and ovisac

The European Zoological Journal
The family Eudrilidae is remarkable among other earthworms for the occurrence of internal fertilization. Also, the female reproductive system in this family is unique due to the evolutionary tendency to unify individual elements into a complex system ...

Groundwater environmental DNA metabarcoding reveals hidden diversity and reflects land‐use and geology

Molecular Ecology, Volume 32, Issue 13, Page 3497-3512, July 2023., 2023
Abstract Despite being the most important source of liquid freshwater on the planet, groundwater is severely threatened by climate change, agriculture, or industrial mining. It is thus extensively monitored for pollutants and declines in quantity. The organisms living in groundwater, however, are rarely the target of surveillance programmes and little ...

Aliens in caves: the global dimension of biological invasions in subterranean ecosystems

Biological Reviews, Volume 98, Issue 3, Page 849-867, June 2023., 2023
ABSTRACT Alien species are a significant threat to natural ecosystems and human economies. Despite global efforts to address this challenge, the documented number of alien species is rapidly increasing worldwide. However, the magnitude of the impact of alien species may vary significantly across habitats.

Parallel duplication and loss of aquaporin‐coding genes during the “out of the sea” transition as potential key drivers of animal terrestrialization

Molecular Ecology, Volume 32, Issue 8, Page 2022-2040, April 2023., 2023
Abstract One of the most important physiological challenges animals had to overcome during terrestrialization (i.e., the transition from sea to land) was water loss, which alters their osmotic and hydric homeostasis. Aquaporins are a superfamily of membrane water transporters heavily involved in osmoregulatory processes.

Ovary organization and ultrastructure in six species of Amynthas and Metaphire earthworms (Annelida, Crassiclitellata, Megascolecidae)

Zoology, 2023
Ovaries in earthworms belonging to the family Megascolecidae are paired structures attached to the septum in the anterior part of the XIII segment. They are fan to rosette shaped with numerous rows of growing oocytes, known as egg strings, radiating from the ovary center towards the segmental cavity.

Catch‐All No More: Integrative Systematic Revision of the Genus Allolobophora Eisen, 1874 (Crassiclitellata, Lumbricidae) with the Description of Two New Relict Earthworm Genera

Journal of Zoological Systematics and Evolutionary Research, Volume 2023, Issue 1, 2023., 2023
The taxonomy of earthworms has been riddled by instability, lack of systematically useful characters, and lax diagnoses of some genera. This has led to the use of some genera such as Allolobophora Eisen, 1874 as taxonomic wastebaskets, blurring their evolution and biogeographical history.

An updated checklist and a DNA barcode library for the earthworms (Crassiclitellata, Oligochaeta) of Corsica, France

Zoosystema, 2022
Available studies of the earthworm fauna of Corsica reported a total of 36 species, but this regional diversity is probably underestimated considering the relatively modest sampling efforts achieved so far. We conducted a sampling campaign in the context of the program “Our Planet Reviewed”, with the aim to increase sampling coverage and to analyze ...

Phylogenomic analyses reveal a Palaeozoic radiation and support a freshwater origin for clitellate annelids

Zoologica Scripta, Volume 49, Issue 5, Page 614-640, September 2020., 2020
Abstract Clitellata is a major clade of Annelida comprising nearly all freshwater and terrestrial annelids as well as several marine species. We investigated clitellate phylogenetic relationships using transcriptomes sampled from 74 taxa (64 clitellates and 10 polychaetes), including multiple representatives of nearly all major clitellate higher taxa ...
