Crustacea Iii Malacostraca Eucarida

1990
Abstract The Decapoda is the largest natural grouping within the Mala¬ costraca. In all decapods the thoracic segments are fused dorsally to a carapace, a fold of which extends ventrally on each side of the animal, enclosing the gills and constituting a branchial chamber.

Morphology and evolution of Malacostraca

2014
In this dissertation project comparative morphological studies on the nervous system, mandible structure and sensory equipment of Decapoda and Peracarida are presented and interpreted with regard to the evolution of the taxa. This is a cumulative dissertation and the results were obtained in several separate publications.

Ocular reflecting pigments of some malacostraca

Journal of Experimental Marine Biology and Ecology, 1971
Abstract Eyes of nineteen malacostracan crustaceans (sixteen from coastal, three from deep water) have been examined for purines and pteridines, with a view to determining their role as reflecting pigments. White shrimp, Penaeus setiferus , received most attention; other animals examined were one isopod, one stomatopod, eight penaeids, six ...

Survey and Distribution of Crustacea Malacostraca in Poland

Crustaceana, 1993
AbstractThe paper presents a survey of Polish malacostracan fauna. In two tables the distribution of freshwater and Baltic species is presented according to the regionalization of the country used in "Catalogus Faunae Poloniae". Figures present some interesting distributions of freshwater malacostracan taxa.

Freshwater origin of Bathynellacea (Malacostraca)

Crustaceana, 2014
There are two opposing hypotheses on the origin of Bathynellacea, a marine and a freshwater one. According to the marine hypothesis, Bathynellacea invaded continental groundwater from the sea via the interstitial of marine beaches (“two-step model”), whereas according to the freshwater hypothesis the groundwater was reached from the sea via fresh ...

Origin of Antarctic Isopoda (Crustacea, Malacostraca)

Marine Biology, 1992
An analysis of the horizontal and the vertical zonation of the Antarctic Isopoda, combined with knowledge of the geological history of Antarctica and isopod phylogeny, revealed that the isopod family Serolidae and subfamily Arcturinae are likely to have evolved from ancestors that inhabited a cold-temperate Gondwanian province.

Evolution of Optical Design in the Malacostraca (Crustacea)

2002
How much can compound eye structure and optical design tell us about the phylogenetic relationships and evolution of the carriers of the compound eyes, in our case the crustaceans? To answer this question, it is necessary to distinguish between compound eye morphology and the cellular composition of the ommatidia on the one hand, and eye physiology and
