Two new species of the aorid Amphipoda are described from Chichijima Island, Ogasawara Islands in Japan. Aoroides macrops sp. nov. shallow water is characterized by heavily setose male gnathopod 1, coxa which bears several plumose setae anteriorly, and uropod 2 with a short inter-ramal process. This very similar to A. longimerus Ren Zheng, 1996; however, this can be distinguished larger eyes, s...

Remote in vivo scanning of physiological parameters is a major trend in the development of new tools for the fields of medicine and animal physiology. For this purpose, a variety of implantable optical micro- and nanosensors have been designed for potential medical applications. At the same time, the important area of environmental sciences has been neglected in the development of techniques fo...

The Ponto-Caspian amphipod Obesogammarus obesus (Sars, 1894) was first recorded in the Rhine River near Koblenz, Germany in October 2004. Additional records of small numbers of O. obesus from the same location in 2005 and 2006 indicate that this alien species may have become established in the central section of the Rhine River. Ship transport via the Main-Danube Canal, connecting the Danube ba...

Amphipods collected from the Yangtze estuary, Shanghai, China are described as a new species, Sinocorophium dongtanense. It is closely allied to Sinocorophium homoceratum Yu, 1938 but differs markedly in the inner lateral side of peduncular article 4 of male antenna 2 having two rows of teeth.

A new species belonging to a new genus of Maeridae, Papuadocus blodiwai gen. nov., sp. nov., is described from bathyal bottoms of the Bismarck Sea (Papua New Guinea). This genus/species can be distinguished from most other known maerids by right and left maxillas 1 with asymmetrical palps and by gnathopod 2 not sexually dimorphic. Its closest relative is the genus Bathyceradocus also characteri...

Predicting the host range for herbivores has been a major aim of research into plant-herbivore interactions and an important model system for understanding the evolution of feeding specialization. Among many terrestrial insects, host range is strongly affected by herbivore phylogeny and long historical associations between particular herbivore and plant taxa. For small herbivores in marine envi...
