Recent phylogenetic work (Ashelby et al., 2012) has demonstrated the need for a fresh appraisal of the systematic status of some Palaemoninae genera. In the present contribution the accumulated morphological as well as molecular evidence is reviewed. The genera Palaemonetes, Exopalaemon and Coutierella are demonstrated to be junior synonyms of Palaemon, which now contains 83 species. As a resul...

The current knowledge of Sicilian inland water decapod malacostracans is scarce and an updated synopsis on species distribution lacking. Therefore, we reviewed the checklist recent decapods based published unpublished records novel observations with aim providing exhaustive repository, also to be used as a sound baseline for future surveys. Overall, five native occur in study area, i.e., atyid ...

Classical biological control programs often target a pest's region of origin as a likely source for new biological control agents. Here, we use this approach to search for biological control agents of the sunflower stem weevil (Cylindrocopturus adspersus LeConte), an economically important pest of commercial sunflower. We conducted surveys of weevil natural enemy diversity and abundance across ...

In summer, high temperatures are combined w ~ t h severe nocturnal hypoxia In the shallow water of Danish fjords. Under these conditions, the prawns Palaemonetes varians (Leach) and Palaem o n adspersus (Rathke) are spatially separated, with the former occupying the areas of highest temperature and lowest oxygen tension. If kept together, P, adspersus shows aggressive behavlour towards P varian...

Transparency is an effective form of camouflage, but it must be present throughout the entire volume of an animal to succeed. Certain environmental stressors may cause physiological responses that increase internal light scattering, making tissue less transparent and more conspicuous to predators. We tested this in the transparent grass shrimp, Palaemonetes pugio, which is found in shallow estu...
