Predators and resources influence phosphorus transfer along an invertebrate food web through changes in prey behaviour. [PDF]
PLoS ONE, 2013 Predators play a fundamental role in prey trophic behaviour, with indirect consequences for species coexistence and ecosystem functioning. Resource quality and availability also influence prey trophic behaviour, with potential effects on predator-prey ...

Intersexuality in Asellus aquaticus L. parasitized by a Larval Acanthocephalan [PDF]
Nature, 1953 INTERSEXES in Asellus aquaticus L., in which the anterior abdominal appendages are intermediate in form between the male and female condition, have been recorded from time to time and their occurrence has been reviewed by Maercks1. They were always females, 5–8 mm. in length.

Population Genomics Reveals Small-Scale Metapopulation Structure of Two Strictly Aquatic Keystone Species in a Recently Restored Urban River System (Emscher, Germany). [PDF]
Ecol EvolThe study used high‐resolution genetic markers to analyze the metapopulation structure of two aquatic amphipod species, Gammarus pulex and Gammarus fossarum, in an urban river catchment (Emscher, Germany). Strong metapopulation structure was identified, primarily influenced by catchment affiliation, wastewater, in‐stream barriers, and recolonization ...

Adverse effects of bisphenol A on water louse (Asellus aquaticus)
Ecotoxicology and Environmental Safety, 2015 Experiments were performed to study the effects of short and long-term exposure to bisphenol A (BPA) on a freshwater crustacean isopod Asellus aquaticus (L.). Two life stages of isopods were exposed to a range of BPA concentrations, from aqueous and two dietary sources, in the form of with BPA spiked conditioned alder leaf (Alnus glutinosa) discs, or ...

N-banding and nucleolus organisers in Asellus aquaticus (crust. isop.) [PDF]
Heredity, 1977 The N-banding technique was used to stain the nucleolus organiser of the karyotype of Asellus aquaticus (crust. Isop.). Observations were made on the morphological expression of nucleolus organisers as secondary constrictions and the presence of nucleoli in mitotic prophase.

The role of isolation on contrasting phylogeographic patterns in two cave crustaceans
BMC Evolutionary Biology, 2017 Background The underlying mechanisms and processes that prompt the colonisation of extreme environments, such as caves, constitute major research themes of evolutionary biology and biospeleology.

SIMPLE DNA REPEATS AND SEX-CHROMOSOME DIFFERENTIATION IN ASELLUS-AQUATICUS (CRUSTACEA, ISOPODA)
, 1995 The crustacean isopod species Asellus aquaticus does not usually have recognizable sex chromosomes. We previously identified a Y chromosome marked by two heterochromatic bands in some males of a population from the Sarno river near Naples. In this work

Contemporary parallel diversification, antipredator adaptations and phenotypic integration in an aquatic isopod. [PDF]
PLoS ONE, 2009 It is increasingly being recognized that predation can be a strong diversifying agent promoting ecological divergence. Adaptations against different predatory regimes can emerge over short periods of time and include many different traits.
