Tube-building Amphipoda

Leucothoe vaderotti, a new Atlantic Leucothoe (Crustacea, Amphipoda) belonging to the “spinicarpa-clade” (Crustacea, Amphipoda)

Within the international IceAGE project (Icelandic marine Animals: Genetics and Ecology) some leucothoid amphipods (Crustacea) were collected, among them a rather small new species, belonging to the "Leucothoe spinicarpa-clade."

Ampithoidae (Crustacea, Amphipoda) from New Zealand

Ampithoidae is a family of marine Amphipoda with approximately 230 species, belonging to 16 genera. The family has a worldwide distribution as algal dwellers. So far only five species are known from New Zealand. Recent collections and examination of historic collection material added two new species, which are described herein. An overview of and a key to the New Zealand Ampithoidae is provided.

Ampeliscidae (Crustacea, Amphipoda) from the IceAGE expeditions

Ampeliscidae has been recorded extensively from Icelandic waters by many detailed reports. Material collected from the IceAGE (Icelandic marine animals: Genetics and Ecology) 1 and 2 expeditions has resulted in a reasonably expected collection of ampeliscid amphipod species and distributions. However, as seems to be the trend in amphipod systematics, there are ever-present species complexes. Re...

Selecting Optimal Dimensions of Internal Tube in Tube-in-Tube Structural Systems Based on Structural Parameters

Tubular structural systems are one of the most common types of systems in high-rise structures. In the early days of this system, there were imperfections in its design which were overcome over time. The most important modification to rectify these defects is the use of a series of internal frames in addition to the peripheral frames and new systems in the center of the plan to eliminate design...
