In the European lobster Homarus gammarus, rhythmic masticatory movements of the three foregut gastric mill teeth are generated by antagonistic sets of striated muscles that are driven by a neural network in the stomatogastric ganglion. In vitro, this circuit can spontaneously generate a single (type I) motor program, unlike in vivo in which gastric mill patterns with different phase relationshi...

The present study focused on redescription of Gammarus pseudosyriacus (Karaman & Pinkster, 1977) based on new materials from Zagros Mountains and describes a new subspecies of freshwater amphipod, Gammarus pseudosyriacus issatisi subsp. n., from the southern Zagros Mountains. The work is based on morphological and morphometric comparisons. This new subspecies has features similar to Gammarus ps...

Proposed offshore windfarm sites could overlap with the brooding and spawning habitats of commercially important crustacea, including European lobster, Homarus gammarus Edible crab, Cancer pagurus. Concerns have been raised on biological effects Electromagnetic Fields (EMFs) emitted from subsea power cables early life history these species. In this study, ovigerous female H. C. pagurus were exp...

Abstract There is ever-greater need for information about changing marine biodiversity, but such sparse at large spatial or temporal scales. Records distributions of species collected by volunteers can fill gaps in knowledge that cannot yet be addressed more structured sampling. Bayesian occupancy models show great promise estimating trends occurrence through time. This study uses the Sparta mo...
