Determination of the Form of Regenerating Limbs in Asellus aquaticus [PDF]
ABSTRACT The nerve-supply to the regenerating anterior pleopods of Asellus aquaticus influences the rate of regeneration but not the character of the regenerate. The tissues of the locality of the blastema determine the character of the regenerate and also influence the rate and extent of regeneration.

Phenotypic plasticity in response to the social environment: effects of density and sex ratio on mating behaviour following ecotype divergence. [PDF]
The ability to express phenotypically plastic responses to environmental cues might be adaptive in changing environments. We studied phenotypic plasticity in mating behaviour as a response to population density and adult sex ratio in a freshwater isopod (

Island and Rensch’s rules do not apply to cave vs. surface populations of Asellus aquaticus
Body size is a trait of fundamental ecological and evolutionary importance that is often different between males and females (sexual size dimorphism; SSD).

Two out of the three common Asellidae species in Northern Europe are increasing their ranges, aided by human activities. Here we report the discovery of Proasellus coxalis (Dollfuss 1892) in new areas in Norway and the discovery of Proasellus meridianus (

A new species of the genus Niphargus Schiödte, 1849 (Crustacea: Amphipoda), co-occurring with water louse Asellus cf. aquaticus (Linnaeus, 1758) (Crustacea: Isopoda) in deep wells, is described from the Tarkhankut Upland, located in the northwestern part

Locally differentiated cryptic pigmentation in the freshwater isopod Asellus aquaticus
A repeated pattern of background colour matching in animals is an indication that pigmentation may be cryptic. Here, we examine the relationship between pigmentation of the freshwater isopod Asellus aquaticus and background darkness in 29 lakes, wetlands

Caves and other subterranean habitats fulfill the requirements of experimental model systems to address general questions in ecology and evolution. Yet, the harsh working conditions of these environments and the uniqueness of the subterranean organisms ...
