The signal crayfish Pacifastacus leniusculus Dana, 1852 is a successful invasive species in the Iberian Peninsula. This is of particular conservation concern, as fish fauna is highly endemic and also threatened within this ecoregion. The aim of this study was to analyze behavioral interactions and trophic overlap between signal crayfish and native...
Thesis
In this doctoral dissertation the main ecological relationships between the signal crayfish Pacifastacus leniusculus (Dana, 1852) and abiotic –physicochemical parameters of water and habitat features– and biotic factors –algae, branchiobdellidans, benthic invertebrates and fish– are dealt in the rivers of Navarra (northern Spain). First, a bibliogr...

Environmental conditions and host features that influence the abundance of an exotic branchiobdellidan were studied. One of the most widespread invasive crayfish species in Europe is the signal crayfish, Pacifastacus leniusculus (Dana, 1825). Along with this invasive crayfish, other alien species that live on the crayfish’s body surface, such as ba...
Article
The identification of habitat requirements of invasive species is essential to evaluate their spread and to assess the vulnerability of recipient ecosystems. We studied the distribution and abundance of the invasive signal crayfish (Pacifastacus leniusculus) in 43 sites in northern Spain and analysed the relationships with several abiotic and bioti...

Invasive alien species present a global threat to biodiversity, particularly where pathogens and symbionts are involved. Branchiobdellidans are clitellate annelids with an obligate ectosymbiotic association primarily on astacoidean crayfish. There are several examples of branchiobdellidan species adopting a geographically exotic host where endemic...

Review of the state of knowledge of crayfish species in the Iberian Peninsula This paper reviews information relevant to managing the four crayfish species present in the Iberian Peninsula. The red swamp crayfish, Procambarus clarkii, signal crayfish, Pacifastacus leniusculus, and Yabbie, Cherax destructor, are classified as invasive alien species...
