| sea-level changes and palaeo-ranges: reconstruction of ancient shorelines and river drainages and the phylogeography of the australian land crayfish engaeus sericatus clark (decapoda: parastacidae). | historical sea levels have been influential in shaping the phylogeography of freshwater-limited taxa via palaeodrainage and palaeoshoreline connections. in this study, we demonstrate an approach to phylogeographic analysis incorporating historical sea-level information in a nested clade phylogeographic analysis (ncpa) framework, using burrowing freshwater crayfish as the model organism. our study area focuses on the bass strait region of southeastern australia, which is marine region encompassin ... | 2008 | 19120999 |
| food utilisation and digestive ability of aquatic and semi-terrestrial crayfishes, cherax destructor and engaeus sericatus (astacidae, parastacidae). | both engaeus sericatus and cherax destructor are omnivorous crayfishes consuming a variety of food items. materials identified in the faeces of both e. sericatus and c. destructor consisted of mainly plant material with minor amounts of arthropod animals, algae and fungi. the morphology of the gastric mill of c. destructor suggests that it is mainly involved in crushing of food material while the gastric mill of e. sericatus appears to be better suited to cutting of food material. given this, th ... | 2009 | 19127367 |
